JP-A-8-184274

  Since the number of electric blinds controlled by a conventional control device is small and the amount of control and response signals is small, the communication method can be handled with a simple one. However, as the number of electric blinds to be controlled increases, the scale of the control device increases, and the amount of transmission increases, demands for higher transmission speed and improved transmission quality have been desired.

-If there is an error in the transmission signal due to noise in the transmission path, or if the signal disappears due to a signal collision or the like, there is no recovery means, so correct control or response transmission / reception cannot be performed.
-Since the transmission rate between the central control unit and the floor control unit is the same as the transmission rate between the floor control unit and the blind controller, the response time of the system is slow.
-When a floor control device fails, communication transmission / reception processing is delayed unless the failed floor control device is physically removed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an example of the overall configuration of an electric switchgear control system according to the present invention.
The central control device 1 and a plurality of floor control devices 2 are connected by a main bus 5, and the floor control device 2 and a plurality of blind control devices (opening / closing device control devices) 3 are connected by a floor bus 6. The floor control device 2 is equivalent to one on each floor of the building, and N (for example, a maximum of 127) is installed in total, and the blind control device 3 is installed on each floor (for example, a maximum of 255). Therefore, for example, the blind control device 3 is a large-scale system capable of installing a maximum of N × M units (for example, 32,385 units). The blind control device 3 corresponds to each electric blind 4 or a blind group that performs the same operation. A signal representing the open / closed state of the electric blind (for example, elevation height, rotation angle) is received from the encoding. Between the central control device 1 and the floor control device 2, the central control device 1 is an upper device and the floor control device 2 is a lower device, and between the floor control device 2 and the blind control device 3, the floor control device 2 is The host device and the blind control device 3 are the lower devices. The electric blind 4 can be any electric opening / closing device such as a horizontal blind, a low screen, a curtain, and a shutter. Each electric blind 4 can also be controlled individually by the hand controller 7, and in that case, signals can be transmitted and received between the hand controller 7 and the blind control device 3 through a wireless or wired communication line. It has become.

FIG. 2 is a block diagram of the control system of FIG.
The central control device 1 includes a CPU 101, a memory 102, an I / O 103 that inputs / outputs signals to / from the floor control device 2 via the main bus 5, and automatic control execution means 200 that performs automatic control according to a predetermined sequence. And comprising.

  Further, the floor control device 2 has a CPU 121, a memory 122, an I / O 123 that inputs and outputs signals from the central control device 1 through the main bus 5, and a signal from the blind control device 3 through the floor bus 6. And an automatic control execution means 220 for performing processing in accordance with a signal from the central control device 1 and / or a predetermined sequence.

  Further, the blind control device 3 is a CPU 131, a memory 132, an I / O 133 that inputs / outputs signals to / from the floor control device 2 via the floor bus 6, and an automatic control that performs processing in accordance with a signal from the floor control device 2. Execution means 240.

  The means constituting the automatic control execution means 200 of the central controller 1 includes a monitoring sequence 201, a return sequence 202, first to n-th scheduling sequences 203-1 to 203-k, a response collection sequence 204, a clock control sequence 207, etc. There is a means to perform. Means constituting the automatic control execution means 220 of the floor control device 2 include means for executing a notification sequence 208, a monitoring sequence 221, a return sequence 222, a scheduling sequence 223, a clock control sequence 227, etc. As means for configuring the third automatic control execution means 240, there is means for executing a notification sequence 228 and the like.

  In the present invention, as described above, the functions necessary for automatic control are classified for each function, the sequence for executing the functions is modularized, and the means for configuring the module is the unit of the start timing and the overall For example, each module is executed in accordance with the schedule shown in FIG. All the functions shown in FIG. 5 are sequences for automatically controlling the electric blind, but the sequence is not necessarily limited to this, and there are necessary functions and unnecessary functions depending on the system. There are also cases where new functions are added. It is not only very time consuming to change various functions for each system, or to change the sequence each time a change request is made, but it may cause problems due to the change. In the present invention, as shown in the example of FIG. 5, the sequence of each function is modularized for each function, and the time between sequences is determined in advance. Thereby, it is possible to provide a high-quality control system by unifying control processing.

  The basic configuration of each sequence will be described below. Except for the monitoring sequence 201 and the return sequence 202, the other sequences are roughly composed of a sequence consisting of data link establishment, information transfer, and data link termination, as shown in FIGS. 3A and 3B. As shown in 3C, it is composed of a sequence consisting of data link establishment and data link termination.

  Establishing a data link from the central control unit 1 to the floor control unit 2 is a command for confirming whether or not the destination floor control unit 2 can currently respond correctly because the request command 20 is transmitted from the central control unit 1. Yes, and consists of SA (which can be the address of the floor control device 2), UA (which can be the address of the blind control device 3), and ENQ. On the other hand, when the floor control device 2 has received the request command 20 correctly, an affirmative response 21 is issued. The affirmative response 21 is a signal that makes a response indicating that reception has been correctly performed, and includes a UA (Unit Address) and an ACK. Thereby, a data link is established.

  Next, when the data link is established, the central control device 1 transmits a command signal 10 that is one of a control signal, a setting signal, and a status call signal. The distinction between a control signal, a setting signal, and a status call signal is determined by the contents of DATA.

  FIG. 3A shows a case where a control signal or a setting signal is transmitted from the central controller 1 as the command signal 10. When the floor control device 2 correctly receives the control signal or the setting signal, an affirmative response 21 is issued. FIG. 3B shows a case where a state calling signal is transmitted from the central control device 1 as the command signal 10, and a state response signal 11 is output from the floor control device 2.

  The command signal (control, setting, status call signal) 10 uses a telegram with the same character structure as before, and each of these characters is JIS X 5002 “Basic data transmission control procedure”, JIS X 0201 “7 bits and 8 bits”. And a character configuration based on JIS X 5001 “Character configuration on transmission line and usage of horizontal parity”.

  When the positive response 21 or the status response signal 11 from the floor control device 2 is correctly received by the central control device 1 and the information transfer is completed, the data link is terminated. Specifically, a termination command 22 is issued from the central controller 1. The termination command 22 is a message for instructing the floor control device 2 to end this sequence. The request command 20, the acknowledgment 21 and the termination command 22 can be based on JIS X 5002.

  On the other hand, FIG. 4 shows a sequence when the data link cannot be established (when the data link is not established), that is, when transmission between the central control device 1 and the floor control device 2 is not possible. The difference from FIG. 3 is an example in which the response signal is no response 23 or negative response 24 and the request command 20 does not reach the other party correctly.

  That is, the floor control apparatus 2 returns a negative response 24 because the request command 20 cannot be correctly received due to a transmission situation or an apparatus abnormality. Alternatively, no response 23 means that the floor control device 2 does not return any message, and the central control device 1 has transmitted a message but no response message. Therefore, the no-response 23 does not have a message on actual transmission.

  As described above, when the request command 20 does not reach the other party, it is repeatedly transmitted twice, three times, and n times. This sequence is called a retry sequence. This is remedy processing when an error temporarily occurs during transmission or the like.

  As a result of the specified number of retries, it is determined that a data link cannot be established (data link is not established) when transmission / reception with the other party is impossible, and the central controller 1 transmits a termination command 22. As will be described later, the central control device 1 performs processing (separation) for separating the partner floor control device 2 in which the data link has not been established from the target of the system. The departure will be described again in the following monitoring sequence.

  FIG. 4 illustrates the case where the floor control device 2 to be communicated has not correctly received the request command 20, but in the present invention, the messages of the acknowledgment 21, the negative response 24, the command signal 10 and the response signal 11 are transmitted. The retry sequence is executed in all cases including cases where the mutual reception is not possible.

  FIG. 3C represents the monitoring sequence 201. As described above, the monitoring sequence 201 is a sequence in which only the data link is established and the data link is terminated. During the idle time during which the blind 4 is not controlled, the state of the main bus 5 and the floor control device 2 is always checked. This is a sequence for confirming whether or not signals can be transmitted and received correctly. As shown in FIG. 5, the monitoring sequence 201 is always started and monitored at regular intervals when other sequences are not processed.

  As shown in FIG. 6, the monitoring sequence 201 sequentially establishes a data link and terminates the data link for all the floor control devices 2. When processing is performed on all floor control devices 2, the same processing is repeated n1 times. This number of times n1 can be arbitrarily set.

  Here, for example, when an affirmative response 21 is not transmitted from a certain floor control device 2, retry is performed a predetermined number of times n, and if the data link cannot be established even after n times, the floor control is performed. The device 2 is detached. Here, the disconnection is to remove from the control target of the system when a situation in which transmission / reception with the host device cannot be normally performed despite being connected to the system occurs.

  The sequence shown in FIG. 6 shows a state in which the floor control device 2 (floor control device FCU2 in “abnormal” in FIG. 6) repeats a negative response 24 or no response 23 in response to the request command 20. When the response of the request command 20 n times is not possible, it is determined that the floor control device 2 has failed or the bus 5 has failed, and the floor control device 2 (FCU 2) At the same time as the termination command 22 is issued, it is made to leave. Specifically, the central control device 1 stores the floor control device 2 detached in the memory 102 and removes the floor control device 2 from the control target in the subsequent sequences.

  If an abnormal floor control device 2 is always set as a system control target, a wasteful retry sequence is repeated to slow down the system control time. Thus, the abnormal floor control device 2 is set as a system control target. This wasteful time can be eliminated by disengaging from the system. Therefore, the detached floor control device 2 remains out of control until it is returned by the return sequence 202 described below.

  In the above description, in FIG. 6, when the data link is unsuccessfully established, it is disconnected, but the command signal (control or setting signal) 10 and the response signal 11 cannot be received correctly. In the same way, the withdrawal process is performed.

  Since the floor control device 2 that has left the system is abnormal as a device, it is restored by exchanging the device or investigating an abnormality in the bus 5 that is a communication line to be connected. The return sequence 202 performs this return processing.

  As shown in FIG. 3D, in the return sequence 202, the central control device 1 transmits a request command 20 to the detached floor control device 2, and when an affirmative response 21 is returned, the test data is set to DATA. The test data signal 12 to be transmitted is transmitted. When the test data signal 12 is returned, a termination command 22 is returned from the central controller 1. The transmitted data and the returned data are collated, and if they are correct, the floor control device 2 determines that it is in a normal state and returns to the control of the system.

  FIG. 7 shows an example in which a return sequence is performed on the floor control device 2 (FCU 2) detached in FIG.

  In this way, the floor control device 2 to which the establishment of the data link has been restored is returned to the control target. That is, a process of returning the floor control device 2 to be returned from the memory 102 storing the detached floor control device 2 is performed.

  In the present invention, the return sequence 202 is incorporated in the automatic control sequence, and what kind of check is performed at which timing during the automatic control and the return is determined in the automatic control. In the example shown in FIG. 5, the return sequence 202 is directed to the floor control device 2 that is disconnected immediately before the first scheduling sequence 203-1 and the second scheduling sequence 203-2, which are sequences for executing the opening / closing control of the electric blind 4. It is supposed to run. As a result, immediately before the scheduling sequence 203 for performing the opening / closing control of the electric blind 4 which is the main purpose of the present control system, all the restored floor control devices 2 can be returned to be controlled.

  Next, the scheduling sequence 203 is a sequence that is executed at a fixed time, and is executed by the opening / closing control means so as to perform the opening / closing control of each electric blind 4 from the central controller 1. As the scheduling sequence, a plurality of sequences can be set for each type of control content transmitted from the central controller 1, and an arbitrary number of sequences can be created according to the number of control types. Specifically, for example, the first scheduling sequence 203-1 designates all or part of the blinds of the entire building according to the illuminance sent from the illuminance sensor (not shown) to the central control device 1 and the time. Thus, it is possible to set the blinds to rise simultaneously or to apply solar shading control that changes the angle of the slats, and the second scheduling sequence 203-2 can be a control to illuminate the entire blind surface as a pictograph.

  That is, the two types or k types of schedule sequences are classified as sequences having completely different types, orders, etc., and are executed in automatic control at different timings (time).

  FIG. 8 shows a procedure of sequentially transmitting a command signal, that is, a control signal to the plurality of floor control devices 2. The control signal includes floor address and group number data, and also includes a signal indicating the degree of opening / closing thereof. The group number is a minimum unit for performing the same opening / closing operation by the electric blinds 4 belonging to the same floor.

  Next, the response collection sequence 204 is a sequence to be executed after the schedule sequence 203 is executed. When the schedule sequence 203 is executed, the blind control device 3 starts operation based on the control signal from the central control device 1 via the floor control device 2. The blind control device 3 sends the execution state or result to the central control device 1, and the central control device 1 collects the execution state or result. That is, the response collection sequence 204 is a sequence for collecting control responses.

  The response collection sequence 204 is preferably divided and executed when the number of blind control devices 3 is large. In the example of FIG. 5, the response is collected by continuing the sequence of n2 times.

  The clock control sequence 207 is a control sequence of a function for synchronizing the clocks of the central control device 1 and the floor control device 2, that is, a time adjustment control sequence, and may be executed about once a day.

  The above sequences 201 to 204 and 207 are sequences that operate in response to a command signal from the central control device 1, while the notification sequence 208 is a sequence in which a command signal is transmitted from the floor control device 2 to the central control device 1. As shown in FIG. 9, when the floor control device 2 is in an abnormal state and cannot receive a command from the central control device 1, the main function of this sequence is the notification of the state or the blind control device 3 In response to a response that is not a command from the central controller 1, specifically, when an opening / closing operation or setting operation is performed by the hand controller 7, the information is transmitted to the central controller 1. In this case, a data link is established from the floor control device 2 to the central control device 1, and after the information is transferred, the data link is terminated.

  This notification sequence 208 needs to be processed as an important and quick response in terms of system control. Therefore, the sequence is executed with a waiting time Tsq1 shorter than the sequence waiting time Tsq2 of the sequences 201 to 204 and 207.

  FIG. 5A is an explanatory diagram illustrating the relationship of the waiting time Tsq of each sequence. In this example, there are four types of waiting times Tsq1 to Tsq4 as the waiting time of the sequence, and the respective time relationships are Tsq1 <Tsq4 <Tsq2 <Tsq3. In this way, the priority order is determined by giving a time difference, and the notification sequence 208 is made the highest priority execution sequence by shortening the waiting time Tsq1 of the notification sequence 208.

  The above description is a sequence performed between the central control device 1 and the floor control device 2, but the same can be performed between the floor control device 2 and the blind control device 3.

  That is, the monitoring sequence 221 of the automatic control execution unit 220 of the floor control device 2 is the same sequence as the monitoring sequence 201. The monitoring sequence 201 is performed asynchronously with the monitoring sequence 221, and as shown in FIG. 10, the blind control device 3 is monitored by being always activated at regular intervals in the time zone when the floor control device 2 is vacant. . When the blind control device 3 that cannot establish the data link is found by this monitoring sequence 221, the blind address of the blind control device 3 is notified to the central control device 1 by the notification sequence 208 and recorded in the memory 102 of the central control device 1. Is done.

  The return sequence 222 is also executed in the same manner as the return sequence 202. As shown in FIG. 11, for example, the floor control device 2 performs a return sequence for the blind control device 3 that has been detached before the schedule sequence is started. Since the schedule sequence is a sequence that is executed at a fixed time as described above, the floor control device 2 determines immediately before the schedule sequence is started, and the schedule sequence is started by the determination. Is determined, the return sequence 222 can be started.

  The blind control device 3 whose data link establishment has been recovered by the return sequence 222 is notified to the central control device 1 by the notification sequence 208.

  Alternatively, instead of causing the blind control device 3 to return in the return sequence 222, a request signal is sent to the blind control device 3 via the floor control device 2 by the return sequence 202 of the central control device 1, as shown in FIG. And an affirmative response can be obtained from the blind control device 3.

  In the scheduling sequence 223, the control signal sent from the central control device 1 according to the scheduling sequence 203 is sequentially sent to the corresponding blind control device 3. In the transmission to the blind control device 3, the data link establishment and data link termination are the same (not shown in FIG. 8).

  The clock control sequence 227 can be omitted, but when the hand controller 7 is provided and the hand controller 7 is provided with a time display function, between the floor control device 2 and the blind control device 3. A clock control sequence 227 for synchronizing the clocks may be performed, and the clocks may be synchronized between the blind control device 3 and the local controller 7.

  The automatic control execution means 240 of the blind control device 3 has a notification sequence 228. As described above, the notification sequence 228 transmits information to the floor control device 2 when an opening / closing operation or a setting operation is performed by the hand controller 7. Even in this case, the data link is established from the blind control device 3 to the floor control device 2 and the data link is terminated after the command signal is transmitted.

  Next, FIG. 13 is a block diagram illustrating examples of different bus arrangements between the central control device 1 and the floor control device 2 and between the floor control device 2 and the blind control device 3. In the example shown in FIG. 1, the central control device 1 is connected to only one channel communication line as the main bus 5. On the other hand, in FIG. 13, two lines of the main bus 5 are prepared, two channels are prepared, and two channels can be communicated simultaneously. As a result, the transmission time can be transmitted about twice as long in the two channels. The floor control device 2 may be 127 floor control devices at the maximum of the system, and the transmission time is halved by 2 channels, the response time of the system (time until the response is returned by control) is greatly increased. It can be shortened.

  The central control device 1 can be realized by a personal computer, but in recent years, the processing capacity of the personal computer has become faster, and at the same time several communication channels can be connected to increase the transmission efficiency. The configuration can be easily realized.

  Similarly, in FIG. 1, the floor control device 2 is connected to only one channel communication line as the floor bus 6, but in FIG. 13, a plurality of floor buses 6 can be prepared and communicated by a plurality of channels. I am doing so. Since the maximum number of blind control devices 3 (for example, 255) that can be connected to the floor bus 6 is larger than that of the normal floor control device 2, it is necessary to increase the response time of the system. In order to increase the response time of the system, it is general that it can be realized simply by increasing the communication speed. However, in the electric blind system, since the number of connected devices is large and the transmission distance is long, it is technically and costly to increase the transmission speed. . For this reason, multi-channel buses are an effective solution.

  Also, in FIG. 1 or FIG. 13, the transmission speed of the bus 5 may be higher than the transmission speed of the bus 6, thereby transferring information between each floor control device 2 and the blind control device 3 having a low transmission speed. Can be performed in parallel, the system response time can be shortened by increasing the transmission speed between the central control device 1 and the plurality of floor control devices 2.

  In the above example, each sequence for establishing a data link or the like is mainly described between the central control device 1 and the floor control device 2, and between the floor control device 2 and the blind control device 3. However, it goes without saying that the control may be performed directly between the central control device 1 and the blind control device 3 via the floor control device 2.

1 is an example of the overall configuration of a control system for an electric switchgear according to an embodiment of the present invention. It is a block diagram of the control system of FIG.
