Description

Elevator system

Technical Field

The present invention relates to a control system for an elevator. In particular to a door opening extension control technology.

Background

In an elevator for goods, etc., a door opening extension button for extending the door opening time of an elevator door is provided in a car. Further, there is a technique of setting the door opening time without providing a special button. For example, patent document 1 discloses a door open time control device in which "an up button for reserving an ascending floor and a down button for reserving a descending floor provided on a hall call operation panel are operated," the door open time of an elevator door is set by a door open time setting control unit based on the pressing time and the number of times of the up button or the down button, and the door open/close control unit performs control to extend or shorten the door open time of the elevator based on the set time. The up button or the down button (abstract extract) "can be replaced with the door open button and the door close button.

If the door-open extension indication button is provided only in the car, it is inconvenient for the user (passenger) to perform an operation once entering the car before the elevator arrives to load the load when the load is carried. Further, according to the door opening extension control technique described in patent document 1, the door opening extension can be instructed in the elevator hall. However, in order to instruct the extension of the door opening, it is necessary to simultaneously press two buttons, i.e., an up button and a down button, and therefore, it is impossible to register a directional call of a destination floor while performing the extension instruction of the door opening. Further, the door opening extension instruction cannot be given to the floor of the lowermost floor and the uppermost floor on which the two buttons of the up button and the down button are not provided.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification, portions having the same functions are denoted by the same reference numerals unless otherwise specified, and redundant descriptions are omitted. The present invention is not limited to the embodiment. The components of the following embodiments include components that can be easily replaced by those skilled in the art or substantially the same components.

In the present embodiment, a special pressing mode (special pressing) of a directional hall call button (hall button) is received, and call registration including an instruction of a destination direction (direction instruction) and an instruction of extension of door opening are received. The special press is accepted by pressing any one of an up button accepting the ascending reservation and a down button accepting the descending reservation among the landing buttons. When the door open extension instruction is received, group management (idle priority determination processing) for giving priority to the idle state is performed to allocate the elevator.

The overall configuration of the elevator system 100 according to the present embodiment for realizing the above-described control will be described below with reference to fig. 1(a), 1(b), and 1 (c).

The elevator system 100 of the present embodiment includes 1 or more elevators 110, 1 or more hall call devices 120, and a group management device 130. Each elevator 110 includes a control device 140 that controls various operations of the elevator 110. The hall call device 120 includes a display unit 124 and at least one of an up button 122 for accepting an ascending reservation and a down button 123 for accepting a descending reservation. In addition, the up button 122 and the down button 123 are referred to as a landing button 121 when there is no need to distinguish them from each other.

Here, the case where 4 elevators 110 (first, second, third, and fourth) and 3 hall call devices 120 are provided is illustrated as an example, but the number of them is not limited to this.

First, the overall structure of the elevator 110 will be described with reference to fig. 2. The elevator 110 of the present embodiment includes a car 111, a counterweight 112, a hoist 113, the control device 140, a main rope 115, a door 117, a load detection device 118, a tail rope 119, an in-car button 127, and a door switch button 128.

In the elevator 110, a car 111 on which passengers are mounted is connected to a counterweight 112 via a main rope 115. The car 111 and the counterweight 112 are raised and lowered in a bucket manner in the hoistway 116 by driving the main rope 115 by the hoist 113. The hoist 113 is driven according to a control signal of the control device 140.

The in-car button 127 is provided in the car 111 and receives registration of the destination floor of the elevator 110. When receiving the registration to the destination floor, the in-car button 127 generates a destination signal corresponding thereto and outputs the destination signal to the control device 140.

The door switch button 128 is provided in the car 110 and receives an instruction to open or close the door 117 of the elevator 110. When door switch button 128 receives a door switch instruction, it outputs a switch signal to control device 140.

The control device 140 performs overall control of various operations of the elevator 110. For example, various display controls such as an elevation control called a control of the hoist 113, a door opening and closing control for instructing opening and closing of the door 117, and the like are performed. The control device 140 will be described in detail later.

Next, the hall call device 120, the group management device 130, and the control device 140 will be described. As described above, in the present embodiment, the direction instruction and the door opening extension instruction are received by pressing the landing button 121. When the door open extension instruction is received, the idle priority determination process is performed. Only the functions related to these processes will be described here.

Fig. 3A is a functional block diagram of the hall call device 120, the group management device 130, and the control device 140 of each elevator 110 according to the present embodiment. The elevator system 100 is provided with a plurality of hall call devices 120 and a control device 140. However, one is representatively shown here.

As shown in fig. 3B, the hall call device 120 according to the present embodiment includes an input/output Interface (IF) unit 125 in addition to the hall button 121 and the display unit 124. The group management device 130 includes an elevator determination unit 134, a special pressing detection unit 135, and a flag storage unit 136. The control device 140 further includes an elevation control unit 141, a door opening/closing control unit 142, a display control unit 143, and a car load detection unit 144.

The hall call device 120 receives call registration of the elevator 110 from the elevator hall via the hall button 121. Then, a call signal corresponding to the accepted call registration is output to the group management apparatus 130.

The landing button 121 is provided in a landing (elevator hall), and a user presses the landing button 121 to receive call registration of the elevator 110 to the landing floor.

The input/output IF unit 125 generates a call signal corresponding to the call registration received via the landing button 121, and outputs the call signal to the special press detection unit 135 of the group management device 130. The call signal is continuously generated and output while the landing button 121 is pressed.

As shown in fig. 3B, the call signal 310 includes floor information 311 indicating the floor of the elevator hall and direction information 312 indicating the direction of the destination. When the call registration by pressing the up button 122 is accepted, information indicating the rise is registered as the direction information 312. When the call registration by pressing down button 123 is accepted, information indicating descent is registered as direction information 312.

When a plurality of hall call devices 120 (or hall buttons 121) are disposed at a hall on the same floor, the call signal 310 may include information that can specify each hall call device 120.

The input/output IF unit 125 is configured by, for example, an AD converter.

The group management apparatus 130 of the present embodiment determines an elevator (referred to as a service elevator) 110 to be allocated to a floor of the hall based on call registration. Then, a call signal 310 is output to the determined service elevator 110, and the elevator travels to the floor of the hall.

When detecting the special push, the group management device 130 outputs a control signal for controlling opening and closing of the door corresponding to the special push to the service elevator 110. The special press is a press type different from the press type of the landing button 121 used for the normal call, and is, for example, a long press, a continuous press, or the like.

The long press is a press mode in which the landing button 121 is continuously pressed for a predetermined threshold time or longer. The threshold time is set to be longer than the normal pressing time. For example around 2 seconds. The continuous pressing is a pressing method of pressing the landing button 121 a plurality of times continuously for a predetermined time.

Upon receiving the call signal 310 from the hall call device 120, the special pressing detection unit 135 determines whether or not there is a special pressing, and outputs the determination result and the call signal 310 to the elevator decision unit 134 and the service elevator 110 determined by the elevator decision unit 134. For example, the output is output to the door switch control unit 142 and the display control unit 143 of the service elevator 110.

In the present embodiment, the user performs the door open extension instruction by the special pressing of the landing button 121. Further, by performing the same special press again using the landing button 121 on the same floor, the previous door open extension instruction can be cancelled.

For example, the special pressing detection unit 135 outputs a door opening extension signal for instructing to extend the opening time of the door 117 when detecting the special pressing. Then, when the special press is detected again during a period from the time when the call registration is accepted to the time when the opening and closing control of the door 117 by the door opening and closing control section 142 is ended, a cancel signal for canceling the instruction by the open door extension signal is outputted.

The special push detection unit 135 determines whether or not a special push has been performed based on the output mode of the call signal 310 received from the input/output IF unit 125. For example, in the case of a long press, whether or not the long press is performed is determined based on the duration of the call signal 310. A threshold value is determined in advance, and when the call signal 310 from the same floor continues for a period of time equal to or longer than the threshold value, the special pressing detection unit 135 determines that there is a special pressing. Otherwise, it is determined that no special press is made. For example, if the registration time of the normal call is set to 0.1 second, the threshold value is set to be longer than the registration time. For example, 2 seconds or the like is set.

When the special press is a multiple press, whether or not the multiple press is performed is determined based on the number of times the call signal 310 is received within a predetermined time. That is, when the call signal 310 is received more than a predetermined number of times within a predetermined time, it is determined that there is a special press.

When the special pressing is determined, the special pressing detection unit 135 refers to the flag storage unit 136. Then, either the door open extension signal or the cancel signal is output as a result of the determination based on the storage state of the flag storage section 136. The output destination is the elevator determination unit 134 and the control device 140 of the service elevator 110 determined by the elevator determination unit 134. When outputting the open extension signal to the elevator determination unit 134, the special push detection unit 135 outputs the open extension signal to the elevator determination unit 134 together with the call signal 310.

On the other hand, when it is determined that there is no special pressing, the special pressing detection unit 135 outputs the call signal 310 to the elevator determination unit 134.

When the special press detection unit 135 of the present embodiment determines that there is a special press, it generates information (referred to as floor information) 321 for identifying the floor on which the call registration is performed as a flag 320, and stores the flag 320 in the flag storage unit 136, as shown in fig. 3C. Then, if the elevator determination unit 134 determines the service elevator 110, information (referred to as an elevator ID)321 for identifying the service elevator 110 is added to the flag 320.

The elevator determination unit 134 determines the service elevator 110 assigned to the call registration based on the signal received from the special press detection unit 135. The call signal 310 is then output to the control device 140 that services the elevator 110 that was determined. The call signal 310 is output to the elevation control unit 141 of the control device 140. In the present embodiment, the elevator ID of the determined service elevator 110 is output to the special push detection unit 135.

The elevator determination unit 134 of the present embodiment performs different determination processes depending on whether or not the door open extension signal is received together with the call signal 310 from the special push detection unit 135. When the door open extension signal is received from the special push detection unit 135, the idle priority determination process is performed.

On the other hand, when the door open extension signal is not received, the service elevator 110 is determined by the normal determination processing, that is, the group management control performed at the time of the normal call. That is, the floor information 311 and the direction information 312 included in the call signal 310 are used to select, for example, a car 111 that is traveling in the same direction as the direction specified by the direction information 312.

In the idle priority determination process, for example, the service elevator 110 is determined from the elevators 110 whose car load is equal to or less than a predetermined threshold (load threshold). When there are a plurality of elevators 110 having a load threshold value or less, for example, the ordinary determination process is performed in these elevators 110. The idle priority determination process will be described in detail later.

When receiving the cancel signal from the special push detection unit 135 while the idle priority determination process is being performed, the elevator determination unit 134 returns to the normal determination process.

As described above, the flag storage unit 136 holds the flag 320 in accordance with the instruction from the special press detection unit 135.

When the special press detection unit 135 generates the cancel signal, the flag 320 is cleared. In addition, the flag 320 is also cleared when the service elevator 110 reaches the destination floor and the door opening and closing control unit 142 performs the door opening extension control.

As described above, the control device 140 of each elevator 110 receives the call signal 310 via the group management device 130, and causes the elevator 110 to travel to the floor specified by the floor information 311 of the call signal 310.

In the control device 140, the elevator control unit 141 receives the call signal 310 and gives a travel command to the hoist 113 so that the car 111 travels to the destination floor in accordance with the call signal 310. The elevator control unit 141 outputs a leveling signal to the door switch control unit 142 when the car 111 reaches the destination floor. Further, the leveling signal may be output to the display control unit 143.

The door opening/closing control unit 142 controls opening and closing of the door 117 of the car 111. The leveling signal is received from the elevation control unit 141, and switching control is performed. For example, if the leveling signal is received, the door 117 is opened, and then if a predetermined time elapses, the door 117 is closed.

In the present embodiment, the door open extension control is performed when the door open extension signal is received from the special push detection unit 135 before the floor leveling signal is received or during the switch control. On the other hand, if the cancel signal is received in the open-door extension control, the open-door extension control is ended.

In the open-door extension control, for example, the door 117 is extended to be opened for a predetermined time period in addition to the normal open time period. The set time is, for example, 30 seconds.

The display control unit 143 controls various displays of the elevator 110. In the present embodiment, in addition to the various display controls that are normally performed, when the door opening is extended, a display (door opening extension display) that notifies the user of the extension is performed. In the door open extension display, for example, "door open extension" or the like is displayed on the display unit 124 as shown in fig. 1 (c). In the open door extension display, for example, either the pressed up button 122 or the pressed down button 123 of the hall call device 120 may be lit in a color different from normal to be flashed in a predetermined pattern. Specifically, if the color is generally orange, the color is lit by green.

The car load detection unit 144 outputs the load of the car 111 detected by the load detection device 118 to the elevator determination unit 134. The load may be detected and output at predetermined time intervals, or may be detected and output in accordance with an instruction from the elevator determination unit 134.

The group management device 130 and the control device 140 according to the present embodiment each include a CPU, a memory, and a storage device. The functions of the respective units are realized by loading and executing a program stored in advance in the storage device into the memory by the CPU.

In addition, all or part of the functions may be realized by hardware such as an ASIC (Application Specific Integrated Circuit), an FPGA (field-programmable gate array), or a Circuit.

In addition, various data used for processing of each function and various data generated in the processing are stored in a memory or a storage device. For example, the flag storage unit 136 is constructed in a memory.

[ Special Press detection treatment ]

Next, an example of the flow of the special pressing force detection process performed by the special pressing force detection unit 135 will be described. Fig. 4 is a process flow of the special press detection process according to the present embodiment. Here, the following case will be described as an example: the special press is a long press, and when the long press is not detected, no signal is output.

The special push detection unit 135 monitors the call signal 310 from the input/output IF unit 125. Then, if the call signal 310 is detected (step S1101), the duration thereof is monitored.

When the call signal 310 is detected for a predetermined time or more, that is, when the long press is detected (step S1102), the special press detection unit 135 refers to the flag storage unit 136.

If the flag 320 of the floor identical to the call signal 310 is not stored in the flag storage unit 136 (yes in step S1103), the call signal 310 and the door open extension signal are output to the elevator determination unit 134 (step S1104). Then, the floor information 321 is registered in the flag 320 (step S1105).

Next, the special push detection unit 135 waits for a notification from the elevator determination unit 134 regarding the determination of the service elevator 110 (step S1106), and if the notification is received, outputs a door open extension signal to the service elevator 110 (step S1107). Here, the elevator ID of the service elevator 110 is acquired as a notification of the decision of the service elevator 110.

Then, the special pressure detection unit 135 stores the elevator ID322 in the flag 320 (step S1108), and ends the processing.

On the other hand, in step S1103, when the flag 320 of the same floor as the call signal 310 is stored in the flag storage unit 136 (no), the special push detection unit 135 outputs a cancel signal (step S1109). This is because it is determined that the second long press is performed on the landing button 121 on the same floor.

The cancel signal is output to the elevator decision section 134 or the service elevator 110. In the present embodiment, for example, the elevator decision unit 134 is output at a timing when the service elevator 110 is not decided. On the other hand, after the service elevator 110 is determined, the service elevator 110 is output. The status is determined by the information stored in the flag 320, that is, when only the floor information 321 is stored, a cancel signal is output to the elevator determination unit 134, and when the elevator ID322 is also stored, the cancel signal is output to the service elevator 110 specified by the ID.

After the cancel signal is output, the special push detection unit 135 clears the flag 320 (step S1110), and the process ends.

In step S1102, when the long press is not detected, the special press detection unit 135 directly ends the process.

When the special push is a multiple push, if the call signal 310 is detected multiple times within a predetermined time in step S1102, the process is performed as a case where the special push is detected. Similarly, when the call signal 310 of the predetermined output pattern is detected by another method, the processing is developed as the case where the special press is detected.

[ Elevator decision processing ]

Next, an example of an elevator determination process flow performed by the elevator determination unit 134 will be described. Fig. 5 is a process flow of the elevator determination process according to the present embodiment.

In the present embodiment, when the special pressing detection unit 135 detects a special pressing, the service elevator 110 is determined with priority given to the idle state. In other cases, the determination is made by a general group management method. This processing is started when the call signal 310 is received from the special push detection unit 135.

When receiving the door open extension information together with the call information 310, the elevator determination unit 134 performs the idle priority determination process (step S1203). The present process is described in detail later.

When the service elevator 110 is determined by the idle priority determination processing (yes in step S1204), the elevator determination unit 134 notifies the special pressure detection unit 135 of the elevator ID of the elevator 110 (step S1205). Then, the call signal 310 is output to the service elevator 110 (step S1206), and the process ends.

On the other hand, when the door open extension signal is not received in step S1202 (no) and when the service elevator is not determined in step S1204 (no), the elevator determination unit 134 performs a normal determination process (step S1209) to determine the service elevator, and the process proceeds to step S1206. In step S1204, it is not determined that the service elevator has received the cancel signal in the idle priority determination process.

[ Idle priority determination processing ]

Next, an example of the idle priority determination processing flow in step S1203 will be described. Fig. 6 is a process flow of the idle priority determination process of the elevator determination unit 134 according to the present embodiment.

The elevator determination unit 134 first determines the presence or absence of an elevator 110 equal to or less than the load threshold (step S1301). For example, the load threshold is determined in advance to be 30% or less of the rated load.

If it is determined in step S1301 that the elevator 110 having the load threshold value or less is present (yes), the elevator 110 is determined as the service elevator 110 (step S1302), and the process is terminated. Here, when there are a plurality of elevators 110 having a load threshold value or less, these elevators can be determined by performing normal determination processing.

If there is no elevator 110 having a load threshold value or less (no at step S1301), it is first determined whether or not a cancel signal has been received from the special press detection unit 135 until that point in time (step S1303). When the cancel signal is received (yes at step S1303), the process ends in a state where the service elevator is not determined (step S1304).

On the other hand, if the cancel signal is not received in step S1303 (no), the process returns to step S1301 to continue monitoring the elevator 110 having a load threshold or less until a predetermined time elapses from the start of the idle priority processing (step S1305).

If the elevator 110 having the load threshold value or less is not found even after the lapse of the predetermined time (yes at S1305), the elevator to be serviced is determined by the normal determination processing (step S1306), and the processing is terminated.

The elevator determination unit 134 determines the service elevator 110 as described above.

In the above-described idle priority processing, the service elevator 110 is determined from the elevators 110 having a load threshold value or less, but the present invention is not limited thereto.

For example, the configuration may be such that the most vacant elevator 110 is selected among the elevators 110 in operation. That is, the elevator 110 with the smallest load is determined as the service elevator 110. At this time, when the cancel signal is received in the decision process, the idle priority decision process is ended in a state where the service elevator is not determined.

In the above embodiment, the elevator system 100 including the plurality of elevators 110 has been described as an example. However, the number of elevators 110 may be 1. At this time, the group management device 130 may not be present. The control device 140 included in the elevator 110 includes a special pressing detection unit 135.

When the elevator 110 is 1, a call signal 310 generated by pressing the landing button 121 is output to the special press detection section 135 and the lifting control section 141. The lift control unit 141 moves the car 111 in accordance with the call signal 310. On the other hand, the special push detector 135 outputs a door open extension signal to the door open/close controller 142 and the display controller 143 when detecting the special push, and outputs a cancel signal to the door open/close controller 142 and the display controller 143 when determining that the cancel instruction is issued.

In the above embodiment, the special push detection unit 135 is configured to output the door open extension signal and the cancel signal to the control device 140 of the service elevator 110, but the present invention is not limited to this. For example, all of the outputs may be configured to be output to the control device 140 serving the elevator 110 via the elevator determination unit 134. Further, the elevator determination unit 134 may output a door open extension signal to the control device 140 of the service elevator 110, and the special push detection unit 135 may output only a cancel signal.

As described above, the elevator system 100 of the present embodiment includes: an input/output IF unit 125 that receives a call registration generated by pressing a directional landing button (landing button 121) provided at a landing and outputs a call signal 310 in response to the pressing; a special press detection unit 135 for outputting door open extension information when the output mode of the call signal 310 is a predetermined mode; an elevator control section 141 that causes the car 111 to travel to a floor of the hall in accordance with the call signal 310; and a door opening and closing control unit 142 that controls opening and closing of the door 117 of the car 111 on which the floor at the landing is leveled, wherein the door opening and closing control unit 142 extends the opening time of the door 117 when the door opening extension signal is output from the special pressing detection unit 135.

According to the present embodiment, the presence or absence of the door open extension instruction is determined based on the output mode of the call signal 310 output by pressing the landing button 121. The call signal 310 is also used for an instruction to raise or lower the elevator car 111, as in the case of a normal call signal. Therefore, according to the present embodiment, the elevator 110 traveling in the same direction as the pressed landing button 121 can be caused to travel to the landing where the call registration is performed, and the extension by opening the door can be performed.

That is, the passenger can simultaneously perform call registration and door open extension instruction of the elevator 110 traveling in the direction coincident with the destination floor. Therefore, convenience is improved.

The above-described effect can be obtained by pressing the landing button 121 provided in the related art. That is, convenience can be improved without adding a new hardware configuration, and cost is excellent. Further, since no new hardware is added, the burden of operation on the passenger is small. In particular, when a long press is used as the special press, the door opening extension instruction can be intuitively operated.

Generally, the door opening extension instruction is a case where a plurality of cargos are to be transported, a case where a wheelchair is used, or the like. According to the present embodiment, when it is determined that there is an extension instruction for opening the door, the service elevator 110 is selected from the plurality of elevators 110 with priority given to the idle state. Therefore, the convenience of the user can be further improved.

The present invention is not limited to the above embodiment, and includes various modifications. The above-described embodiments are for easy understanding of the present invention, and are not limited to having all the configurations described.
