By the way, in recent years, there is an increasing need to make an automatic door function as an evacuation route when a fire breaks out in a building. However, in the above-mentioned conventional automatic door, as described above, when the door is manually opened and moved, the door becomes heavy. Therefore, the door should be opened and moved to the extent that the user can pass through to evacuate. Therefore, for example, it is necessary to separately provide an opening mechanism (for example, a panic opening mechanism) on the door, which may increase the installation cost of the door.

An object of the present invention is to solve the above-mentioned problems in the prior art, and to provide a control system capable of reducing the installation cost of a door.

The control system according to claim 1 is a control system that controls the opening and closing of a door that opens and closes an opening of a building in order to solve the above-mentioned problems and achieve the object. Whether or not the object has entered the first region located in the vicinity of the prospective direction with respect to the door, or the second region which is a region different from the first region and in which the object may be pinched by the door. A control mode is set according to the presence / absence of the input of the fire signal by the first determination means, the input means for receiving the input of the fire signal for notifying the fire, and the input means, and the set control mode is set. An opening / closing control means for controlling the opening / closing of the door based on the door is provided, and the opening / closing control means sets the control mode to the fire mode when the input of the fire signal is received by the input means. When the fire mode is set and the door is manually moved by a predetermined distance in the opening direction, the open / closed state of the door is a pass target regardless of at least the determination result of the first determination means. The door is electrically opened and moved until it becomes a passable state, and after a predetermined time elapses, the door is electrically operated until the opening is fully closed by the door. Close and move.

The control system according to claim 2 is the control system according to claim 1, wherein the passable state is a fully open state in which the opening is fully opened by the door.

The control system according to claim 3 is provided in the control system according to claim 1 or 2 by providing the predetermined distance to a door frame provided on the peripheral edge of the opening or another door adjacent to the door. The swallowing portion is smaller than the swallowing depth of the swallowing portion for accommodating the end portion of the door on the door end side.

The control system according to claim 4 is the control system according to any one of claims 1 to 3, wherein the open / close control means does not accept the input of the fire signal by the input means. , The moving speed at the time of opening / closing movement of the door when the control mode is set to the normal mode and the fire mode is set, and the moving speed at the time of opening / closing movement of the door when the normal mode is set. It was slower than.

The control system according to claim 5 supplies electric power to each part of the control system in the control system according to any one of claims 1 to 4 in a power failure state in which the building is out of power. It is equipped with a power supply means.

The control system according to claim 6 is the control system according to claim 5, wherein when the open / close control means is set to the fire mode and the door is openly moved, the building is moved. In a non-power failure state where there is no power failure, the door is electrically opened and moved until the passable state is reached, and after a predetermined time elapses, the door is electrically closed and moved and stopped until the fully closed state is reached. In the power failure state, the door is electrically closed and moved to stop until the fully closed state is reached.

The control system according to claim 7 determines whether or not the driving means for electrically opening and closing the door is in an overloaded state in the control system according to any one of claims 1 to 6. The opening / closing control means controls the opening / closing of the door based on the determination result of the second determination means regardless of whether or not the control mode is set to the fire mode. ..

According to the control system according to claim 1, the control mode is set according to the presence or absence of input of a fire signal by the input means, and the door opening / closing control means is provided based on the set control mode. Compared with the conventional technology (system using a mechanical automatic closing device), the opening / closing control of the door can be performed by the opening / closing control means regardless of the control mode, and for example, it is not necessary to separately provide the door opening mechanism on the door or the like. , It is possible to reduce the installation cost of the door. Further, when the opening / closing control means is set to the fire mode and the door is manually moved by a predetermined distance in the opening direction, the door opening / closing state is at least regardless of the determination result of the first determination means. The door is electrically opened and moved until it becomes passable, and after a predetermined time, the door is electrically closed and moved until it is fully closed. It is not necessary, and when a fire is occurring in the building, the door can be easily and quickly opened and moved, and the door can function as an evacuation route. Further, as compared with the case where the door is opened and closed based on the determination result of the first determination means, it is possible to prevent the first determination means from erroneously detecting smoke as a passing target and moving the door open, and the door is a fire door. Can function as.

According to the control system according to claim 2, since the passable state is fully open, the door is fully opened when the door is manually moved by a predetermined distance in the opening direction when a fire is occurring in the building. The door can be electrically opened and moved until it is in a state, and it is possible to reliably pass the passage target.

According to the control system according to claim 3, the predetermined distance is made smaller than the swallowing depth of the door frame provided on the peripheral edge of the opening or the swallowing portion provided on the other door adjacent to the door. Compared to the case where the distance is larger than the swallowing depth, it is possible to avoid leaving the door in the half-open state by manually operating the door less than the predetermined distance in the fully closed state, and between the door and the door frame. Alternatively, it is possible to prevent the flame of a fire or the like from flowing out through the gap formed between the doors.

According to the control system according to claim 4, the opening / closing control means sets the moving speed at the time of opening / closing movement of the door when the fire mode is set, and at the time of opening / closing movement of the door when the normal mode is set. Since it is slower than the moving speed, it is less likely that the passing object will collide with the door, or the passing target will be smaller than when the moving speed is the same as when opening and closing the door when the normal mode is set. The impact force when colliding with the door can be reduced, and when a fire is occurring in the building, the safety of the passing object can be improved even when the door opening / closing control is performed without using the judgment result of the first judgment means. It will be easier to secure.

According to the control system according to claim 5, since the power supply means for supplying electric power to each part of the control system in the power failure state is provided, power is supplied to each part of the control system in the power failure state. It is possible to operate the control system reliably even in a power failure state.

According to the control system according to claim 6, when the open / close control means is set to the fire mode and the door is open and moving, the door is electrically operated until the door becomes passable in the non-power failure state. After that, the door is electrically closed and moved to stop until it is fully closed, and when a power failure occurs, the door is electrically closed and moved to stop until it is fully closed. The door can be reliably fully closed in the non-power failure state and the power failure state, and the door can function as a fire door.

According to the control system according to claim 7, the opening / closing control means controls the opening / closing of the door based on the determination result of the second determination means regardless of whether the control mode is set to the fire mode. , Regardless of whether the control mode is set to the fire mode, the opening / closing control of the door can be performed based on the determination result of the second determination means, and it becomes easy to secure the safety of the passing object.

(Opening and closing process)
Next, the opening / closing process executed by the control system 60 configured in this way will be described. In the following description, in the description of each process shown in FIGS. 7 to 9, the step is abbreviated as “S”.

The opening / closing process is a process for controlling the opening / closing of the door 40. In this opening / closing process, a process of electrically driving the drive unit 50 is performed in order to open / close the door 40 based on the control mode. The timing of executing this opening / closing process is arbitrary, but in the embodiment, the power of the drive unit 50 and the control system 60 is turned on via the power switch of the operation unit, and then started after the preparatory process is completed. It will be explained as a thing. Here, the "preparation process" is a process executed before the process of opening / closing process. For example, by moving the door 40 to open / close at a relatively slow speed, the control unit 74 is moved to the fully closed position (starting point of control). It is a concept that includes learning processing and the like so that the position) and the fully open position can be correctly determined. Further, as a premise of the opening / closing process, specifically, it is assumed that the opening / closing state of the door 40 is a fully closed state and the power supply source is a commercial power source.

When the opening / closing process is activated, as shown in FIG. 7, the opening / closing control unit 74e in SA1 determines whether or not the input of the fire signal is accepted by the input unit 71.

The method for determining whether or not the input of the fire signal is accepted is arbitrary, but in the embodiment, whether or not the input of the fire signal is continuously accepted (or the input of the fire signal is accepted). Judgment is made based on whether or not the recovery signal has been received after the fire has been received. Here, when the input of the fire signal is continuously accepted (or when the recovery signal is not accepted after the input of the fire signal is accepted), the input of the fire signal is accepted. Judgment, if the input of the fire signal is not continuously accepted (or if the recovery signal is accepted after the input of the fire signal is accepted), it is determined that the input of the fire signal is not accepted. To do. The "recovery signal" is a signal for restoring the control mode from the fire mode to the normal mode.

Then, when it is determined that the input of the fire signal is not accepted (SA1, No), the open / close control unit 74e sets the control mode to the normal mode and activates the normal mode processing (SA2), and normally After the mode processing (SA2) is completed, the process shifts to SA1. If it is determined that the input of the fire signal is accepted (SA1, Yes), the control mode is set to the fire mode and the fire mode processing (SA3) is started to perform the fire mode processing (SA3). After the completion, the process shifts to SA1, and the processes from SA1 to SA3 are repeated thereafter. Here, the "normal mode" means a mode among the control modes when the input of the fire signal is not accepted. Further, the "fire mode" means a mode among the control modes when the input of the fire signal is accepted.

(Open / close processing-normal mode processing)
Next, the normal mode processing of SA2 in FIG. 7 will be described. The normal mode process is a process for controlling the opening / closing of the door 40 when the control mode is set to the normal mode.

When the normal mode processing is activated, as shown in FIG. 8, first, in SB1, the control unit 74 determines whether or not it is in a non-power failure state.

The method for determining whether or not this is a non-power failure state is arbitrary, but in the embodiment, the determination is made based on whether or not the input of a signal including the non-power failure state information is accepted by the input unit 71. If the input of the signal is accepted, it is determined that the power is not in a non-power failure state, and if the input of the signal is not accepted, it is determined that the power is in a power failure state (note that the processing of SC4 described later is also performed). The same applies).

Then, the control unit 74 shifts to SB2 when it is determined that it is in a non-power failure state (SB1, Yes), and shifts to SB6 when it is determined that it is not in a non-power failure state (SB1, No).

In SB2, the open / close state determination unit 74d receives the input of the signal including the open / close state detection information via the input unit 71, and determines the open / close state of the door 40 based on the open / close state detection information included in the received signal. The determined state is specified as the current open / closed state of the door 40.

The method of specifying the open / closed state of the door 40 is arbitrary, but in the embodiment, the count value included in the received open / closed state detection information is a set value stored in advance in the data recording unit 75. It is determined whether or not it matches any of the set values corresponding to the open / closed state of the door 40, and the open / closed state of the door 40 is specified based on this determination result (the same applies to the processing of SC1 described later). .. Specifically, when the count value is counted so as to be "0" in the fully closed state, "100" in the fully open state, and "0" in the fully closed state again, the count value becomes When it is determined that the value matches the set value corresponding to the fully closed state (hereinafter, referred to as "first set value". For example, the first set value = 0), the open / closed state of the door 40 is set to the fully closed state. Identify. Further, when it is determined that the count value matches the set value corresponding to the fully opened state (hereinafter, referred to as "second set value". For example, the second set value = 100), the door 40 is opened and closed. Specify the state as a fully open state. Further, the count value is a value between the first set value and the second set value (for example, a value from 1 to 99), and is a predetermined time before the count value (for example, 0.5 seconds before). Etc.) When it is determined that the value matches the same value as the count value, the open / closed state of the door 40 is specified as the half-open state. Further, it is determined that the count value is a value between the first set value and the second set value, and matches a value that is larger than the count value before a predetermined time. In this case, the open / closed state of the door 40 is specified as the open movement state. Further, it is determined that this count value is a value between the first set value and the second set value, and matches a value that is smaller than the count value before a predetermined time. In this case, the open / closed state of the door 40 is specified as the closed moving state.

In SB3, the first determination unit 74a, the second determination unit 74b, and the third determination unit 74c transmit the signal including the first detection information, the signal including the second detection information, and the third detection information via the input unit 71. The input of the including signal is received, and based on the first detection information and the second detection information included in the received signal, it is determined whether or not the object has entered the first region E1 or the second region E2, and the reception is performed. It is determined whether or not the drive unit 50 is in an overload state based on the third detection information included in the signal, and the first detection unit 61, the second detection unit 62, and the third detection are based on these determination results. Identify the detection status of the part.

Here, the method of specifying the detection state of the first detection unit 61, the second detection unit 62, and the third detection unit is arbitrary, but for example, the detection state of the first detection unit 61 is the first determination unit. The 74a determines whether or not the received first detection information is information indicating that the object has entered the first region E1, and is determined to be information indicating that the object has entered. Is the state in which the first detection unit 61 is detecting, and when it is determined that the information indicates that the object has not entered, the first detection unit 61 has not detected the information. Identify as being. Further, regarding the detection state of the second detection unit 62, the second determination unit 74b specifies the detection state of the first detection unit 61 in substantially the same manner. Further, regarding the detection state of the third detection unit, the third determination unit 74c determines whether or not the received third detection information is information indicating that the overload state is present, and in the overload state. When it is determined that the information indicates that there is, it is specified that the third detection unit is in the detected state, and when it is determined that the information indicates that the overload state is not present, the third detection unit is in the detected state. It is specified that the detection unit is not detecting (the same applies to the processing of SC2 described later).

In SB4, the open / close control unit 74e is based on the open / closed state of the door 40 specified in SB2 and the detection states of the first detection unit 61, the second detection unit 62, and the third detection unit specified in SB3. , The first open / close control information is specified. Specifically, from the first open / close control information stored in the first control information table 75a, the open / closed state of the door 40 specified by SB2, and the first detection unit 61 specified by SB3, The first open / close control information corresponding to the detection state of the second detection unit 62 and the third detection unit is extracted, and the extracted information is specified as the first open / close control information used for the SB5 process described later.

In SB5, the open / close control unit 74e performs open / close control (hereinafter referred to as “first open / close control”) of the door 40 based on the first open / close control information specified in SB4, and then ends the normal mode processing. The process returns to the opening / closing process of FIG.

The specific control content of the first open / close control is as shown below in the embodiment. In the following opening / closing control of the door 40, when the opening / closing state of the door 40 is the fully closed state, the opening / closing control unit 74e sets the state of the locking device to the locked state, and the timing of opening or closing the door 40. The state of the locking device shall be unlocked.

For example, when the door 40 is fully closed and the passage target passes through the opening 3, the passage target enters the first region E1, and another passage target enters the second region E2. When the door 40 is not entered, the door 40 opening / closing control (hereinafter, referred to as “normal opening / closing control”) shown below is performed. That is, first, the open / closed state of the door 40 = fully closed state is specified by SB2, the detection state of the first detection unit 61 = ○ (detection state), and the detection state of the second detection unit 62 = by SB3. When x (not detected state) is specified and the first open / close control information = first open control (control number = first open / close control information corresponding to A13) is specified in SB4, The door 40 is opened and moved at SB5. Next, during the open movement of the door 40, the open / closed state of the door 40 = the open movement state is specified by SB3, the detection state of the first detection unit 61 = ○, the detection state of the second detection unit 62, and the second detection state of the SB3. 3 When the detection state = × of the detection unit is specified and the first open / close control information = state continuation control (control number = first open / close control information corresponding to D14) is specified in SB4, SB5 Continue the open movement of the door 40 at. Next, by exiting from the first region E1 after the open / closed state of the door 40 is fully opened, the open / closed state of the door 40 = fully opened state is specified by SB2, and the detection of the first detection unit 61 is performed by SB3. By specifying the state and the detection state = × of the second detection unit 62, the first opening / closing control information = closing control (control number = first opening / closing control information corresponding to B11) is specified in SB4 after a predetermined time has elapsed. If this is the case, the door 40 is closed and moved at SB5 after a predetermined time has elapsed. Then, when the open / closed state of the door 40 becomes the fully closed state, the open / closed state of the door 40 = the fully closed state is specified by SB2, and the detection state of the first detection unit 61 and the detection state of the second detection unit 62 are specified by SB3. When the detection state = × is specified and the first open / close control information = state continuation control (control number = first open / close control information corresponding to A11) is specified in SB4, the door 40 is specified in SB5. Continue to stop the opening / closing movement of. By such first opening / closing control, the passage target can pass through the opening 3.

When entering the area E2, the opening / closing control of the door 40 shown below is performed. That is, first, the open / closed state of the door 40 = fully closed state is specified by SB2, and the detection state of the first detection unit 61 and the detection state of the second detection unit 62 = ○ are specified by SB3, so that SB4 When the first opening / closing control information = the first opening / closing control (the first opening / closing control information corresponding to the control number = A14) is specified in the above, the door 40 is opened and moved by the SB5. Next, when the open / closed state of the door 40 is the open movement state, another passage target is sandwiched by the door 40, so that the open / closed state of the door 40 = the open movement state is specified by SB2, and the first detection unit is specified by SB3. By specifying 61, the detection state of the second detection unit 62, and the detection state of the third detection unit = ○, the first open / close control information = stop control (control number = C18 corresponding to the first open / close control) in SB4. When the control information) is specified, the opening movement of the door 40 is stopped at SB5. Next, when the open / closed state of the door 40 is in the half-open state, the passage target exits from the first region E1 and the other passage target exits from the state of being sandwiched by the door 40, so that the open / closed state of the door 40 in SB2 = The half-open state is specified, and the detection state of the first detection unit 61 and the detection state of the second detection unit 62 = × are specified by SB3, so that the first open / close control information = closure control after a predetermined time elapses in SB4. When (the first open / close control information corresponding to the control number = C11) is specified, the door 40 is closed and moved by SB5 after a predetermined time has elapsed. Then, when the open / closed state of the door 40 becomes the fully closed state, the open / closed state of the door 40 = the fully closed state is specified by SB2, and the detection state of the first detection unit 61 and the detection state of the second detection unit 62 are specified by SB3.

Continue to stop the opening / closing movement of. By such first opening / closing control, it is possible to reduce the impact force when the door 40 collides with another passing object when the opening / closing state of the door 40 is the open movement state.

Further, for example, when the door 40 is in the half-opened state and the passage target passes through the opening 3, the passage target enters the first region E1, and the other passage target is in the second region. When not entering E2, the opening / closing control of the door 40 shown below is performed. That is, first, the open / closed state of the door 40 = the half-open state is specified by SB2, the detection state of the first detection unit 61 = ○, and the detection state of the second detection unit 62 = × are specified by SB3. When the first open / close control information = state continuation control (control number = first open / close control information corresponding to C13) is specified in SB4, the SB5 continues to stop the open / close movement of the door 40. Next, when the door 40 is half-opened and the passage target exits the first region E1, the detection state of the first detection unit 61 and the detection state of the second detection unit 62 = × are specified by SB3. When the first open / close control information = the closing control (the first open / close control information corresponding to the control number = C11) is specified in the SB4 after the elapse of the predetermined time, the door is opened in the SB5 after the elapse of the predetermined time. 40 is closed and moved. Next, when the open / closed state of the door 40 is the closed movement state, the passage target re-enters the first region E1, the open / closed state of the door 40 = the closed movement state is specified by SB2, and the first detection unit is specified by SB3. By specifying the detection state of 61 = ○, the detection state of the second detection unit 62, and the detection state of the third detection unit = ×, the first open / close control information = stop control and then the first open control (control) in SB4. When the number = first open / close control information corresponding to E14) is specified, the door 40 is opened and moved after the closing movement of the door 40 is stopped by SB5. Next, after the open / closed state of the door 40 is fully opened, the passage target exits the first region E1, so that the open / closed state of the door 40 = fully open state is specified by SB2, and the first detection is performed by SB3. By specifying the detection state of the unit 61 and the detection state of the second detection unit 62 = ×, the SB4 determines the first open / close control information = the closing control after a predetermined time elapses (control number = first open / close control corresponding to B11). Information) is specified, the door 40 is closed and moved by SB5. Next, when the open / closed state of the door 40 is the closed moving state, the passage target is sandwiched by the door 40, so that the open / closed state of the door 40 = the closed moving state is specified by SB2, and the detection of the first detection unit 61 by SB3. By specifying the state and the detection state of the third detection unit = 〇 and the detection state of the second detection unit 62 = ×, the first open / close control information = stop control is performed by SB4, and then the first open control (control number =). When the first open / close control information corresponding to E16) is specified, the door 40 is opened and moved after the closing movement of the door 40 is stopped by SB5. Subsequently, the open / closed state of the door 40 becomes the fully open state after the passage target comes out of the state of being sandwiched by the door 40, so that the open / closed state of the door 40 = the fully opened state is specified in SB2, and the first in SB3. By specifying the detection state of the detection unit 61 and the detection state of the second detection unit 62 = ×, the SB4 identifies the first opening / closing control information = closing control after a predetermined time elapses (control number = first opening / closing corresponding to B11). When the control information) is specified, the door 40 is closed and moved by SB5. After that, when the open / closed state of the door 40 becomes the fully closed state, the open / closed state of the door 40 = the fully closed state is specified by SB2, and the detection state of the first detection unit 61 and the detection state of the second detection unit 62 are specified by SB3. When the detection state = × is specified and the first open / close control information = state continuation control (control number = first open / close control information corresponding to A11) is specified in SB4, the door 40 is specified in SB5. Continue to stop the opening / closing movement of. With such a first opening / closing control, when the passage target is sandwiched by the door 40 in the closed movement state, the opening / closing movement of the door 40 can be stopped, and it becomes easy to ensure the safety of the passage target.

Further, as described above, when it is determined by SA1 that the power failure is not in a non-power failure state, the open / close control unit 74e executes the power failure process in SB6, then ends the normal mode process, and performs the open / close process in FIG. go back. Here, the "power failure process" means a process when the control mode is set to the normal mode in the power failure state.

The specific processing content of this power failure processing is arbitrary, but in the embodiment, the power supply source is switched to the power supply unit 51 (as described above, this switching is automatically performed by the switching unit). Will be). In addition, the state of the locking device is set to the unlocked state. Further, the door 40 is manually opened and closed without controlling the opening and closing of the door 40 based on the determination result of the first determination unit 74a, the determination result of the second determination unit 74b, and the determination result of the third determination unit 74c. To be in a possible state (so-called free door 40). By such processing, when the control mode is set to the normal mode in the power failure state, the door 40 can be reliably opened and closed by manual operation while suppressing the power consumption of the power supply unit 51. However, the present invention is not limited to this, and for example, when the amount of electricity stored in the power supply unit 51 is relatively large, the determination result of the first determination unit 74a, the determination result of the second determination unit 74b, and the determination of the third determination unit 74c. The opening / closing control of the door 40 may be performed based on the result.

By the above-mentioned normal mode processing, the door 40 can be electrically opened and closed in a non-power failure state, and the door 40 can be manually opened and closed in a power failure state. It is possible to pass reliably. Further, the opening / closing control of the door 40 can be performed based on the determination result of the third determination unit 74c, and the safety of the passing object can be ensured.

(Open / close processing-fire mode processing)
Next, the fire mode processing of SA3 in FIG. 7 will be described. The fire mode process is a process for controlling the opening / closing of the door 40 when the control mode is set to the fire mode.

When the fire mode processing is activated, as shown in FIG. 9, first, the open / close state determination unit 74d in SC1 receives the input of the signal including the open / close state detection information via the input unit 71, and the received signal is used. The open / closed state of the door 40 is determined based on the included open / closed state detection information, and the determined state is specified as the current open / closed state of the door 40.

In SC2, the third determination unit 74c receives the input of the signal including the third detection information via the input unit 71, and the drive unit 50 is in the overloaded state based on the third detection information included in the received signal. Whether or not it is determined, and the detection state of the third detection unit is specified based on these determination results.

In the SC3, the open / close control unit 74e receives an input of a signal including the open / close state detection information via the input unit 71, and opens the door 40 in the opening direction (in FIG. 1) based on the open / close state detection information included in the received signal. , Left) Specify whether or not a manual operation to move a predetermined distance has been performed. Here, the method of setting the "predetermined distance" is arbitrary, but in the embodiment, it is the swallowing portion 15 of FIG. 2 provided in the door frame 10 (specifically, the right vertical frame 12). It is set smaller than the swallowing depth D of the swallowing portion 15 for accommodating the end portion of the door 40 on the door end side. As a result, compared to the case where the predetermined distance is made larger than the swallowing depth D, it is possible to prevent the door 40 from being left in the half-open state due to the manual operation of the door 40 less than the predetermined distance in the fully closed state. It is possible to prevent the flame of a fire or the like from flowing out through the gap formed between the 40 and the door frame 10.

Further, the method of specifying whether or not the manual operation has been performed is arbitrary, but in the embodiment, the count value of the open / closed state detection information received by the SC3 within a predetermined time after the SC1 is processed. Is specified based on whether or not is greater than or equal to a predetermined value (specifically, a value corresponding to the above-mentioned predetermined distance) than the count value of the open / closed state detection information received by SC1, and the value is greater than or equal to the above-mentioned predetermined value. If there is, it is specified that the manual operation has been performed, and if it is not more than the predetermined value, it is specified that the manual operation has not been performed.

Returning to FIG. 9, in SC4, the control unit 74 determines whether or not there is a non-power failure state. Then, the control unit 74 shifts to SC5 when it is determined that it is in a non-power failure state (SC4, Yes), and shifts to SC7 when it is determined that it is not in a non-power failure state (SC4, No).

In SC5, the open / close control unit 74e is based on the open / closed state of the door 40 specified in SC1, the detection state of the third detection unit specified in SC2, and the presence / absence of the manual operation specified in SC3. 2 Specify the open / close control information. Specifically, from the second open / close control information stored in the second control information table 75b, the open / closed state of the door 40 specified by SC1 and the detection state of the third detection unit specified by SC2. , And the second opening / closing control information corresponding to the presence / absence of the manual operation specified in SC3 is extracted, and the extracted information is specified as the second opening / closing control information used in the processing of SC6 described later.

Here, in SC5, regardless of the detection state of the first detection unit 61 and the detection state of the second detection unit 62 (that is, the detection state of the first detection unit 61 and the detection state of the second detection unit 62 are not considered. The reason for specifying the second open / close control information as described above is as shown below. That is, when a fire is occurring in a building in the fully open state, when the first detection unit 61 or the second detection unit 62 erroneously detects smoke as a passage target and moves the door 40 open, the opening 3 is opened. This is to avoid such a problem because the heat or flame of the fire may flow in and out through the fire (the same applies to the specification of the third open / close control information in the SC7).

Further, in SC5, the reason for specifying the second opening / closing control information based on the presence / absence of the manual operation specified in SC3 is as shown below. That is, as described above, in the fire mode processing, the second open / close control is performed without considering the detection state of the first detection unit 61 and the detection state of the second detection unit 62, so that the detection state of the first detection unit 61 Alternatively, since the second open / close control cannot be performed by using the detection state of the second detection unit 62 as a trigger, the second open / close control is performed by using the presence / absence of manual operation as a trigger as an alternative (particularly, in the embodiment). As shown in the second control information table 75b of FIG. 5 described above, it is a trigger for performing the second opening control when the opening / closing state of the door 40 is the fully closed state. The third opening / closing control in the SC7. The same applies to the identification of information).

In SC6, the opening / closing control unit 74e performs opening / closing control of the door 40 (hereinafter referred to as “second opening / closing control”) based on the second opening / closing control information specified in SC5, and then ends the fire mode processing. The process returns to the opening / closing process of FIG.

The specific control content of the second open / close control is as shown below in the embodiment. In the second opening / closing control described below, the opening / closing control unit 74e sets the state of the locking device to the unlocked state. Further, the method of setting the moving speed at the time of opening / closing movement of the door 40 when the second opening / closing control is performed is arbitrary, but in the embodiment, the moving speed at the time of opening / closing movement of the door 40 in the normal mode processing. It is set slower than. As a result, the collision of the passage target with the door 40 is reduced, or the passage target is the door 40, as compared with the case where the movement speed at the time of opening / closing movement of the door 40 is the same when the normal mode is set. The impact force at the time of collision can be reduced, and when a fire is occurring in the building, the second opening / closing control is performed without using the judgment result of the first judgment unit 74a and the judgment result of the second judgment unit 74b. Even in such a case, it becomes easier to ensure the safety of the traffic object.

For example, when the door 40 is fully closed and the passage target has entered the first region E1, the second opening / closing control shown below is performed. That is, first, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = × is specified by SC3, so that the second open / close control information = state continuation control (control number =) is specified in SC5. When the second opening / closing control information) corresponding to A21 is specified, the SC6 continues to stop the opening / closing movement of the door 40. Next, when the door 40 is manually operated depending on the passage target, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = 〇 is specified by SC3, so that the SC5 is used. When the second opening / closing control information = the second opening / closing control (control number = the second opening / closing control information corresponding to A22) is specified, the door 40 is opened and moved by the SC6. Next, after the open / closed state of the door 40 is fully opened, the passage target passes through the opening 3, and the open / closed state of the door 40 = the fully opened state is specified by SC1, so that the second is performed by SC5. When the opening / closing control information = closing control (second opening / closing control information corresponding to the control number = B21) is specified after the lapse of a predetermined time, the SC6 closes and moves the door 40 after the lapse of a predetermined time. Then, when the open / closed state of the door 40 is fully closed, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = × is specified by SC3. 2 When the opening / closing control information = state continuation control (control number = second opening / closing control information corresponding to A21) is specified, the SC6 continues to stop the opening / closing movement of the door 40. When the fire mode is set by such a second opening / closing control and the door 40 is manually moved by a predetermined distance in the opening direction, the determination result of the first determination unit 74a and the second determination unit Regardless of 74b, the door 40 can be electrically opened and moved until it becomes passable, and after a predetermined time elapses, the door 40 can be electrically closed and moved until it is fully closed. Therefore, when a fire is occurring in a building in a non-power failure state, the door 40 can be easily and quickly opened and moved, and the door 40 can function as an evacuation route. In particular, since the passable state is in the fully open state, when the door 40 is manually moved by a predetermined distance in the opening direction when a fire is occurring in the building, the door 40 is electrically operated until it is in the fully open state. It can be moved openly, and it is possible to reliably pass the passage target.

Further, for example, when the open / closed state of the door 40 is the open movement state due to the fire mode processing of SA3 being activated during the open movement of the door 40 by the normal mode processing of SA2, the passage target enters the first region E1. If so, the second opening / closing control shown below is performed. That is, first, the open / closed state = open movement state of the door 40 is specified by SC1, and the detection state = × of the third detection unit is specified by SC2, so that the second open / close control information = state continuation is specified by SC5. When the control (second open / close control information corresponding to the control number = D21) is specified, the opening movement of the door 40 is continued by the SC6 (specifically, as described above, during the normal mode processing). (Continue the open movement of the door 40 at a speed slower than the moving speed of the open movement of the door 40). Next, when the open / closed state of the door 40 becomes the fully open state, the open / closed state of the door 40 = the fully opened state is specified by SC1, and the second open / close control information = the closing control after a lapse of a predetermined time (SC5). When the control number = second open / close control information corresponding to B21) is specified, the door 40 is closed and moved by SC6 after a predetermined time has elapsed. Next, when the open / closed state of the door 40 is the closed moving state and the passage target is sandwiched by the door 40, the open / closed state of the door 40 = the closed moving state is specified by SC1, and the detection state of the third detection unit is specified by SC2. When = 〇 is specified, the second open / close control information = second open / close control (control number = second open / close control information corresponding to E22) is specified in SC5 after stop control, in SC6. After stopping the closing movement of the door 40, the door 40 is opened and moved. After that, the open / closed state of the door 40 becomes the fully open state, and the passage target escapes from the state of being sandwiched by the door 40, so that the open / closed state of the door 40 = the fully opened state is specified by the SC1 and the SC5. When the second opening / closing control information = closing control (second opening / closing control information corresponding to the control number = B21) is specified after the lapse of a predetermined time, the SC6 closes and moves the door 40 again after the lapse of a predetermined time. Then, when the open / closed state of the door 40 is fully closed, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = × is specified by SC3. 2 When the opening / closing control information = state continuation control (control number = second opening / closing control information corresponding to A21) is specified, the SC6 continues to stop the opening / closing movement of the door 40. By such a second opening / closing control, the door 40 can be surely fully closed in a non-power failure state, and the door 40 can function as a fire door. Further, when the passage target is sandwiched by the door 40 in the closed movement state, the closing movement of the door 40 can be stopped and the door 40 can be opened and moved, so that the safety of the passage target can be easily ensured.

In SC7, the open / close control unit 74e is based on the open / closed state of the door 40 specified in SC1, the detection state of the third detection unit specified in SC2, and the presence / absence of the manual operation specified in SC3. 3 Specify the open / close control information. Specifically, from the third open / close control information stored in the third control information table 75c, the open / closed state of the door 40 specified by SC1 and the detection state of the third detection unit specified by SC2. , And the third opening / closing control information corresponding to the presence / absence of the manual operation specified in SC3 is extracted, and the extracted information is specified as the third opening / closing control information used in the processing of SC7 described later.

In SC8, the opening / closing control unit 74e performs opening / closing control of the door 40 (hereinafter, referred to as “third opening / closing control”) based on the third opening / closing control information specified in SC7, and then ends the fire mode processing. The process returns to the opening / closing process of FIG.

The specific control content of the third open / close control is as shown below in the embodiment. In the following third opening / closing control, the opening / closing control unit 74e sets the state of the locking device to the unlocked state. Further, the method of setting the moving speed at the time of opening / closing movement of the door 40 when the third opening / closing control is performed is arbitrary, but in the embodiment, the moving speed at the time of opening / closing movement of the door 40 in the normal mode processing. It is set to be slower than, and slower than the moving speed at the time of opening / closing movement of the door 40 of SC6. For example, when the third opening / closing control is executed as the learning process, the opening / closing movement of the door 40 in the learning process is performed. It may be set to be substantially the same as the moving speed at the time (however, not limited to this, for example, when the third opening / closing control is not executed as the learning process, the moving speed at the time of opening / closing movement of the door 40 of the SC6 is used. It may be set to be the same).

For example, when the fire mode processing in the power failure state is continuously executed, the door 40 is in the fully closed state, and the passage target has entered the first region E1, the following item is shown. 3 Opening and closing control is performed. That is, first, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = × is specified by SC3, so that the third open / close control information = state continuation control (control number =) is specified in SC7. When the third opening / closing control information) corresponding to A31 is specified, the SC8 continues to stop the opening / closing movement of the door 40. Next, when the door 40 is manually operated depending on the passage target, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = 〇 is specified by SC3, so that the SC7 is used. When the third open / close control information = second open control (control number = third open / close control information corresponding to A32) is specified, the door 40 is opened and moved by the SC8 (here, as described above, as described above). Since the fire mode processing in the power failure state is continuously executed, the open / closed state of the door 40 = the open movement state is specified by SC1, and the detection state of the third detection unit = × is specified by SC2. , SC7 specifies the third open / close control information = state continuation control (control number = third open / close control information corresponding to D31), so that the open movement of the door 40 is continued at SC8). Next, after the open / closed state of the door 40 is fully opened, the passage target passes through the opening 3, and the open / closed state of the door 40 = the fully opened state is specified by SC1, so that the third is performed by SC7. When the opening / closing control information = closing control (third opening / closing control information corresponding to the control number = B31) is specified after the lapse of a predetermined time, the SC8 closes and moves the door 40 after the lapse of a predetermined time. Then, when the open / closed state of the door 40 is fully closed, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = × is specified by SC3. 3 When the opening / closing control information = state continuation control (control number = third opening / closing control information corresponding to A31) is specified, the SC8 continues to stop the opening / closing movement of the door 40. When the fire mode is set by such a third opening / closing control and the door 40 is manually moved by a predetermined distance in the opening direction, the determination result of the first determination unit 74a and the second determination unit Regardless of 74b, the door 40 can be electrically opened and moved until it becomes passable, and after a predetermined time elapses, the door 40 can be electrically closed and moved until it is fully closed. Therefore, when a fire breaks out in a building in a power failure state, the door 40 can be easily and quickly opened and moved, and the door 40 can function as an evacuation route (however, the power supply unit 51 can be used). Only when power is stored).

Further, for example, when the fire mode processing of SA3 is activated while the door 40 is being opened and moved in the normal mode processing of SA2 in a non-power failure state and the power failure state occurs, the passage target is the first. When entering the 1st region E1, the following third opening / closing control is performed. That is, first, the open / closed state = open movement state of the door 40 is specified by SC1, and the detection state = × of the third detection unit is specified by SC2, so that the third open / close control information = stop control is specified by SC7. When (the third open / close control information corresponding to the control number = D31) is specified (here, as described above, the normal mode processing in the non-power failure state is switched to the fire mode processing in the power failure state, so the SC7 is used. The third open / close control information = stop control is specified), the open movement of the door 40 is stopped by the SC7. Next, the open / closed state of the door 40 becomes the half-open state while the passage target enters the first region E1, and the open / closed state of the door 40 = the half-open state is specified by the SC1. 3 When the opening / closing control information = closing control (third opening / closing control information corresponding to the control number = C31) is specified after the elapse of the predetermined time, the door 40 is closed and moved by the SC8 after the elapse of the predetermined time. Next, after the open / closed state of the door 40 is fully closed, the door 40 is manually operated depending on the passage target, so that the open / closed state of the door 40 = fully closed state is specified by SC1 and manually operated by SC3. When the operation = 〇 is specified and the third open / close control information = second open control (control number = third open / close control information corresponding to A32) is specified in SC7, the door 40 is specified in SC8. (Here, since the fire mode processing in the power failure state is continuously executed, the open / closed state of the door 40 = the open movement state is specified by SC1, and the detection state of the third detection unit is specified by SC2. By specifying = ×, the third open / close control information = state continuation control (third open / close control information corresponding to the control number = D31) is specified in SC7, so that the door 40 can be opened and moved in SC8. Will continue). Next, after the open / closed state of the door 40 is fully opened, the passage target passes through the opening 3, and the open / closed state of the door 40 = the fully opened state is specified by SC1, so that the third is performed by SC7. When the opening / closing control information = closing control (third opening / closing control information corresponding to the control number = B31) is specified after the lapse of a predetermined time, the SC8 closes and moves the door 40 after the lapse of a predetermined time. Next, when the door 40 is closed and moving, the passage target is sandwiched by the door 40, so that the open / closed state of the door 40 = the closed moving state is specified by SC1, and the detection state of the third detection unit is specified by SC2. When = 〇 is specified, the third open / close control information = stop control and then the second open control (control number = third open / close control information corresponding to E32) is specified in SC7, in SC8. After stopping the closing movement of the door 40, the door 40 is opened and moved again (again, since the fire mode processing in the power failure state is continuously executed, the opening movement of the door 40 is continued as described above. Door). After that, the open / closed state of the door 40 becomes the fully open state, and the passage target escapes from the state of being sandwiched by the door 40, so that the open / closed state of the door 40 = the fully opened state is specified by the SC1 and the SC7. When the third opening / closing control information = closing control (third opening / closing control information corresponding to the control number = B31) is specified after the lapse of a predetermined time, the SC8 closes and moves the door 40 again after the lapse of a predetermined time. Then, when the open / closed state of the door 40 is fully closed, the open / closed state of the door 40 = fully closed state is specified by SC1, and the manual operation = × is specified by SC3. 3 When the opening / closing control information = state continuation control (control number = third opening / closing control information corresponding to A31) is specified, the SC8 continues to stop the opening / closing movement of the door 40. By such a third opening / closing control, the door 40 can be surely fully closed in a power failure state, and the door 40 can function as a fire door. Further, when the passage target is sandwiched by the door 40 in the closed movement state, the door 40 can be opened and moved after the closing movement of the door 40 is stopped, and it becomes easy to ensure the safety of the passage target.

By the fire mode processing as described above, the opening / closing control unit 74e can control the opening / closing of the door 40 regardless of the control mode as compared with the conventional technique (system using the mechanical automatic closing device). Since it is not necessary to separately provide the door opening mechanism, it is possible to reduce the installation cost of the door 40. Further, as compared with the case where the door 40 is opened and closed based on the determination result of the first determination unit 74a and the determination result of the second determination unit 74b, the first determination unit 74a and the second determination unit 74b make the smoke pass through. It is possible to prevent the door 40 from being opened and moved due to an erroneous detection, and the door 40 can function as a fire door. Further, as described above, in the fire mode processing, the opening / closing control of the door 40 is performed ignoring the detection state of the first detection unit 61 and the detection state of the second detection unit 62, but the door 40 is opened. As a trigger for movement, the door 40 is manually operated instead of the operation of the dedicated release switch provided separately. Therefore, the door 40 can be easily and quickly opened and moved while reducing the installation cost of the automatic door 1. It becomes possible to do.

(effect)
As described above, according to the embodiment, the opening / closing control unit 74e is provided which sets the control mode according to the presence / absence of the input of the fire signal by the input unit 71 and controls the opening / closing of the door 40 based on the set control mode. Therefore, as compared with the prior art (a system using a mechanical automatic closing device), the opening / closing control unit 74e can control the opening / closing of the door 40 regardless of the control mode. For example, the door 40 or the like is provided with a separate door opening mechanism. Since it is not necessary, the installation cost of the door 40 can be reduced. Further, when the opening / closing control unit 74e is set to the fire mode and the door 40 is manually moved by a predetermined distance in the opening direction, the door 40 is at least regardless of the determination result of the first determination means. The door 40 is electrically opened and moved until the open / closed state of the door 40 is in a passable state, and then the door 40 is electrically closed and moved until it is fully closed after a predetermined time has passed. It is not necessary to separately provide an opening switch for the door 40, and the door 40 can be easily and quickly opened and moved when a fire is occurring in the building, and the door 40 can function as an evacuation route. Further, as compared with the case where the door 40 is opened and closed based on the determination result of the first determination unit 74a and the determination result of the second determination unit 74b, the first determination unit 74a and the second determination unit 74b make the smoke pass through. It is possible to prevent the door 40 from being opened and moved due to an erroneous detection, and the door 40 can function as a fire door.

Further, since the passable state is fully open, if the door 40 is manually moved by a predetermined distance in the opening direction when a fire is occurring in the building, the door 40 is electrically operated until it is fully opened. It can be moved openly, and it is possible to reliably pass the passage target.

Further, since the predetermined distance was made smaller than the swallowing depth D of the swallowing portion 15 provided in the door frame 10 provided on the peripheral edge of the opening 3, the predetermined distance was made larger than the swallowing depth D as compared with the case where the predetermined distance was made larger than the swallowing depth D. Therefore, by manually operating the door 40 that is less than a predetermined distance in the fully closed state, it is possible to avoid being left in the half-open state, and a fire occurs through the gap formed between the door 40 and the door frame 10. It is possible to prevent the inflow and outflow of flames and the like.

Further, since the opening / closing control unit 74e slows the moving speed of the door 40 when the door 40 is opened / closed when the fire mode is set, the moving speed when the door 40 is opened / closed is slower than the moving speed when the door 40 is opened / closed when the normal mode is set. Compared with the case where the moving speed at the time of opening / closing movement of the door 40 is the same when the normal mode is set, the collision of the passing object with the door 40 is reduced, or the passing target collides with the door 40. It is possible to reduce the impact force at the time, and it is easy to ensure the safety of the passing object even when the opening and closing control of the door 40 is performed without using the judgment result of the first judgment means when a fire is occurring in the building. Become.

Further, since the power supply unit 51 that supplies power to each part of the control system 60 in the power failure state is provided, power can be supplied to each part of the control system 60 in the power failure state, and control is performed even in the power failure state. It is possible to operate the system 60 reliably.

Further, when the open / close control unit 74e is set to the fire mode and the door 40 is openly moved, in the non-power failure state, the door 40 is electrically opened and moved until it becomes passable, and then a predetermined value is provided. After a lapse of time, the door 40 is electrically closed and moved to stop until it is fully closed, and when a power failure occurs, the door 40 is electrically closed and moved to be stopped until it is fully closed. The door 40 can be reliably fully closed in a power failure state, and the door 40 can function as a fire door.

Further, since the open / close control unit 74e controls the opening / closing of the door 40 based on the determination result of the second determination means regardless of whether the control mode is set to the fire mode, the control mode is set to the fire mode.

It may be set smaller than D, and as an example, since both the doors 41 and 42 can be opened and closed, it is desirable to set it to half or less of the swallowing depth D.

(About the 1st detection unit, the 2nd detection unit, and the 3rd detection unit)
In the above embodiment, it has been described that the automatic door 1 is provided with the first detection unit 61, the second detection unit 62, and the third detection unit, but the present invention is not limited to this. For example, either one of the first detection unit 61 or the second detection unit 62, or the third detection unit may be omitted. In this case, only the determination unit corresponding to the detection unit provided may be provided. As an example, when only the first detection unit 61 is provided, only the first determination unit 74a may be provided. ..

(About the 1st control information table, the 2nd control information table, and the 3rd control information table)
In the above embodiment, it has been explained that the second open / close control information of the second control information table 75b does not completely match the third open / close control information of the third control information table 75c, but the present invention is not limited to this, for example. , The third open / close control information of the third control information table 75c may be completely the same (that is, the second open / close control of the SC6 and the third open / close control of the SC8 are the same).

Further, in the above embodiment, in the second control information table 75b, when the open / close state information = the information indicating the half-open state, the second open / close control information = after a predetermined time has elapsed, regardless of the content of the manual operation information. It was explained that only the information indicating the closure control is stored, but the present invention is not limited to this. For example, in the open / closed state information = information indicating the half-opened state, when the manual operation information = indicating that the manual operation of the door 40 is not performed, the second open / closed control information = the information indicating the closing control after a predetermined time has elapsed. When the manual operation information = the information indicating that the manual operation of the door 40 is being performed is stored in association with each other, the information indicating the second opening / closing control information = the second opening control may be stored in association with each other (note that the information indicating the second opening / closing control) may be stored in association with each other. The same applies to the third control information table 75c).

Further, in the above embodiment, the method of setting the predetermined time shown in various open / close control information stored in the first control information table 75a, the second control information table 75b, and the third control information table 75c is arbitrary. However, for example, it may be set as shown below.

That is, regarding the method of setting the predetermined time shown in the first open / close control information, after the first open / close control information corresponding to the control number = D12 is specified in SB4 of the normal mode processing, the normal mode of the next cycle is executed. When the first open / close control information corresponding to the control number = C11 is specified in the SB4 of the process, the predetermined time indicated in the first open / close control information corresponding to the control number = C11 corresponds to the control number = B11. The predetermined time may be set to be substantially the same as or different from the predetermined time shown in the first open / close control information (as an example, the predetermined time shown in the first open / close control information corresponding to the control number = B11). May be set longer than the time).

Regarding the method of setting the predetermined time shown in the second open / close control information, after the second open / close control information corresponding to the control number = D22 is specified in the SC5 of the fire mode processing, the fire mode of the next cycle is used. When the second open / close control information corresponding to the control number = C21 is specified in the SC5 of the process, the predetermined time indicated in the second open / close control information corresponding to the control number = C21 corresponds to the control number = B21. It may be set to be substantially the same as or different from the predetermined time shown in the second open / close control information (as an example, the predetermined time shown in the second open / close control information corresponding to the control number = B21). May be set longer than the time).

Regarding the method of setting the predetermined time shown in the third opening / closing control information, after the third opening / closing control information corresponding to the control number = D32 is specified in the SC7 of the fire mode processing, the fire mode of the next cycle is used. When the third opening / closing control information corresponding to the control number = C31 is specified in the processing SC7, the predetermined time indicated in the third opening / closing control information corresponding to the control number = C31 corresponds to the control number = B31. The predetermined time may be set to be substantially the same as or different from the predetermined time shown in the third open / close control information (as an example, the predetermined time shown in the third open / close control information corresponding to the control number = B31). May be set longer than the time).

Further, the predetermined time indicated in the first open / close control information corresponding to the control number = B11, the predetermined time indicated in the second open / close control information corresponding to the control number = B21, and the third open / close control corresponding to the control number = B31. Regarding the method of setting the predetermined time shown in the information, for example, these predetermined times may be set to be the same, or at least a part of these predetermined times may be set to be different (as an example, control). The predetermined time shown in the second open / close control information corresponding to the number = B21 and the predetermined time shown in the third open / close control information corresponding to the control number = B31 are shown in the first open / close control information corresponding to the control number = B11. It may be set longer than the specified time).

(About opening and closing process)
In the above embodiment, it has been described that it is determined whether or not the input of the fire signal is accepted only in SA1, but the present invention is not limited to this. For example, it may be determined whether or not the input of the fire signal is accepted during the execution of the normal mode processing (SA2), and if the input of the fire signal is accepted, the fire mode processing (SA3) may be started. .. Further, even if it is determined whether or not the input of the fire signal is accepted during the execution of the fire mode processing (SA3) and the input of the fire signal is not accepted, the normal mode processing (SA2) is started. Good.

Further, in the above embodiment, it has been described that the predetermined distance to be manually moved by the door 40 in SC3 is set to be smaller than the swallowing depth D of the swallowing portion 15, but the present invention is not limited to this, for example. It may be set to be the same as or larger than the swallowing depth D.

Further, in the above embodiment, the moving speed of the door 40 when the door 40 is opened and closed when the fire mode is set is slower than the moving speed when the door 40 is opened and closed when the normal mode is set. Although it has been described that it is set, the speed is not limited to this, and for example, it may be set to be substantially the same as the moving speed when the door 40 is opened and closed when the normal mode is set.

Further, in the above embodiment, it is described that the open / close control unit 74e controls the opening / closing of the door 40 based on the determination result of the third determination unit 74c regardless of whether the control mode is set to the fire mode. However, it is not limited to this. For example, when the control mode is set to the fire mode, the opening / closing control of the door 40 may not be performed based on the determination result of the third determination unit 74c.

Further, in the above embodiment, the open / close control unit 74e is set to the detection state of the third detection unit when the door 40 is in the open / closed state = fully open state, half open state, or fully closed state when the control mode is the normal mode and the fire mode. It has been explained that the opening / closing control of the door 40 is performed regardless of this, but the present invention is not limited to this. For example, regardless of the open / closed state of the door 40, the open / close control of the door 40 may be performed based on the detection state of the third detection unit (that is, is the open / closed state of the door 40 and the control mode set to the fire mode? Regardless of whether or not, the opening / closing control of the door 40 may be performed based on the determination result of the second determination means).

(About the passable state)
In the above embodiment, it has been described that the passable state is a fully open state, but the present invention is not limited to this, and for example, a half open state may be used. In this case, the opening width of the opening 3 in the half-opened state may be set to a length that allows the passage target to pass (for example, 500 mm or more). Further, in the SC6 and SC8 of the fire mode processing, the door 40 is opened and moved until the door 40 becomes passable by manually operating the door 40 depending on the passage target in the fully closed state or the half open state, and then the door 40 is further manually operated. In that case, the door 40 may be moved open to the fully open state.

(Additional note)
The control system of Appendix 1 is a control system that controls the opening and closing of a door that opens and closes an opening of a building, and is a first region located in the vicinity of the opening or the prospective direction with respect to the opening, or the first region. The first determination means for determining whether or not the object has entered the second region, which is a region different from the above and the region where the object may be pinched by the door, and the fire signal for notifying the fire. An input means for receiving an input and an opening / closing control means for setting a control mode according to the presence / absence of input of the fire signal by the input means and performing opening / closing control of the door based on the set control mode are provided. The opening / closing control means sets the control mode to the fire mode when the input of the fire signal is received by the input means, and when the fire mode is set, the door is manually operated. When the door is moved by a predetermined distance in the opening direction, the door is opened and closed until the door is open and closed so that the door can pass through, regardless of the determination result of the first determination means. The door is electrically opened and moved, and after a predetermined time has elapsed, the door is electrically closed and moved until the opening is fully closed by the door.

In the control system of Appendix 1, the passable state is a fully open state in which the opening is fully opened by the door.

In the control system according to Appendix 1 or 2, the control system of Appendix 3 is a swallowing portion provided in a door frame provided on the periphery of the opening or another door adjacent to the door for the predetermined distance. Therefore, it was made smaller than the swallowing depth of the swallowing portion for accommodating the end portion of the door on the door end side.

The control system of Supplementary note 4 is the control system according to any one of Supplementary note 1 to 3, wherein the open / close control means is the control mode when the input of the fire signal is not received by the input means. Was set to the normal mode, and the moving speed at the time of opening / closing movement of the door when the fire mode was set was slower than the moving speed at the time of opening / closing movement of the door when the normal mode was set. ..

In the control system according to any one of the items 1 to 4, the control system of the appendix 5 is a power supply means for supplying electric power to each part of the control system in a power failure state in which the building is out of power. Be prepared.

In the control system according to the appendix 6, the opening / closing control means does not have a power failure when the fire mode is set and the door is openly moved in the control system according to the appendix 5. In the non-power failure state, the door is electrically opened and moved until the passable state is reached, and after a predetermined time elapses, the door is electrically closed and moved and stopped until the fully closed state is reached, resulting in the power failure state. Then, the door is electrically closed and moved to stop until the door is fully closed.

The control system of Appendix 7 is a second determination for determining whether or not the driving means for electrically opening and closing the door is in an overloaded state in the control system according to any one of Appendix 1 to 6. The opening / closing control means controls the opening / closing of the door based on the determination result of the second determination means regardless of whether or not the control mode is set to the fire mode.

(Effect of appendix)
According to the control system described in Appendix 1, a control mode is set according to the presence or absence of input of a fire signal by the input means, and the door opening / closing control means is provided based on the set control mode. Compared with the conventional technology (system using a mechanical automatic closing device), the opening / closing control of the door can be performed by the opening / closing control means regardless of the control mode, and for example, it is not necessary to separately provide the door opening mechanism on the door or the like. It is possible to reduce the installation cost of the door. Further, when the opening / closing control means is set to the fire mode and the door is manually moved by a predetermined distance in the opening direction, the door opening / closing state is at least regardless of the determination result of the first determination means. The door is electrically opened and moved until it becomes passable, and after a predetermined time, the door is electrically closed and moved until it is fully closed. It is not necessary, and when a fire is occurring in the building, the door can be easily and quickly opened and moved, and the door can function as an evacuation route. Further, as compared with the case where the door is opened and closed based on the determination result of the first determination means, it is possible to prevent the first determination means from erroneously detecting smoke as a passing target and moving the door open, and the door is a fire door. Can function as.

According to the control system described in Appendix 2, the passable state is in the fully open state. Therefore, when a fire is occurring in the building and the door is manually moved by a predetermined distance in the opening direction, the fully open state is obtained. The door can be electrically opened and moved until it becomes, and it is possible to surely pass the passage target.

According to the control system described in Appendix 3, the predetermined distance is smaller than the swallowing depth of the door frame provided on the peripheral edge of the opening or the swallowing portion provided on the other door adjacent to the door. Compared to the case where the depth is larger than the swallowing depth, it is possible to avoid leaving the door in the half-open state by manually operating the door less than a predetermined distance in the fully closed state, and it is possible to avoid leaving the door in the half-open state. It is possible to prevent the flame of a fire or the like from flowing in through the gap formed between the doors.

According to the control system described in Appendix 4, the opening / closing control means moves the moving speed at the time of opening / closing movement of the door when the fire mode is set, and the movement at the time of opening / closing movement of the door when the normal mode is set. Since it is slower than the speed, it is less likely that the target will collide with the door, or the target will be the door, compared to the case where the speed is the same as when opening and closing the door when the normal mode is set. It is possible to reduce the impact force when colliding with the door, and when a fire is occurring in the building, the safety of the passing object is ensured even when the door opening and closing control is performed without using the judgment result of the first judgment means. It will be easier to do.

According to the control system described in Appendix 5, since the power supply means for supplying power to each part of the control system in the power failure state is provided, it is possible to supply power to each part of the control system in the power failure state. It is possible to operate the control system reliably even in a power failure state.

According to the control system described in Appendix 6, when the open / close control means is set to the fire mode and the door is open and moving, in the non-power failure state, the door is electrically operated until it becomes passable. After the door is opened and moved, after a predetermined time elapses, the door is electrically closed and moved to stop until it is fully closed, and when a power failure occurs, the door is electrically closed and moved to be stopped until it is fully closed. The door can be reliably fully closed in the non-power failure state and the power failure state, and the door can function as a fire door.

According to the control system described in Appendix 7, the opening / closing control means controls the opening / closing of the door based on the determination result of the second determination means regardless of whether the control mode is set to the fire mode. Regardless of whether or not the control mode is set to the fire mode, the opening / closing control of the door can be performed based on the determination result of the second determination means, and it becomes easy to secure the safety of the passing object.
