Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to an elevator control device, and in particular improves private power generation control when controlling the operation of an elevator using private power generation equipment in a building. The present invention relates to an elevator control device that achieves the following.

(Prior technology) Elevators are operated by power supplied from power generation facilities outside the building such as commercial power sources (hereinafter referred to as purchased power), but in the event of a power outage of this purchased power source, an emergency power source is installed inside the building. The installed private power generation equipment will be operated to generate electricity and supply it to the building.

In general, in-house power generation equipment is an emergency power source and does not have enough power generation capacity to operate the minimum amount of indoor equipment that does not cause chaos in the building, so elevator equipment only has enough power to operate the elevators. The power capacity is only allocated.

Therefore, in elevator control, when the power source is switched from the purchased power source to the privately generated power source, the elevators are sequentially operated one by one to a predetermined evacuation floor. This operation method is hereinafter referred to as private generation control.

After rescuing the passengers in all the elevator cars that were in operation, the next step is to start operating the elevators under the limited power supply capacity, and continue to serve the passengers inside the building. This is hereinafter referred to as continuous private power generation operation.

In such private power generation control operation control, there is a private power generation control automatic operation method that automatically returns the elevator to the evacuation floor in a predetermined order when switching from purchased power to private power generation.

FIG. 3 shows a block diagram of an elevator control device that implements a conventional private generation control automatic operation system, using an example of three elevators. In the figure, reference numeral 1 denotes a private generation control device that controls a plurality of elevators in the same private power generation system as a group, and 28 to 2c are elevator single control devices that respectively control the operation of individual elevators. These elevator single control devices 28 to 2c are controlled by the private power generation control device 1 upon receiving a command when switching to private power generation.

3-a is a contact A of a power purchase detection relay (not shown) that detects and operates while the purchased power is being supplied from the building to the elevator equipment; When the current power source switches to a privately generated power source,
This is the a contact point of a self-generated detection relay (not shown) that detects this and operates. It is assumed that the power purchase detection relay and the private power generation detection relay are interlocked so that they do not operate at the same time.

Reference numeral 5 indicates a private generation traffic control signal given from the private generation traffic control device 1 to each elevator single control device 28 to 2c of cars A to C. Reference numeral 6 denotes a completion signal outputted from each of the individual elevator control devices j2a to 2c to the private generation control operation device 1 at the time of returning to the evacuation floor.

FIG. 4 is a diagram illustrating details of the transmission and reception signals shown in FIG. 3, and the elevator single control devices 28 to 2c are designated by the reference numeral 2 as a representative. In the figure, 5-1 to 5-4 are private power generation control signals 5, and among these, 5-1 is a power purchase supply mode signal which is an amplified contact signal of the power purchase detection relay that is turned on when power is purchased. , 5-2 is a private power generation supply mode signal obtained by amplifying the a contact signal of the private power generation detection relay that is turned on during private power generation. Further, 5-3 is a return command signal for returning to an evacuation floor, which is given to each elevator single control device 12a to 2c in a predetermined order from the private generation control control device 1 during the private generation control automatic operation. First, it is output to Unit A, and when Unit A returns to the evacuation floor, it is then output to Unit B, and when Unit B returns to the evacuation floor, it is then output to Unit C. are output in order. 5
-4 is a continuous operation command for private engine control, which is given to only one predetermined unit after all units have returned.
Here, for example, it is given to the elevator single control device 2a of car A.

6-1, 6-4 is the completion signal 6, and among these,
6-1 indicates a return completion signal that is output from the single control device of the elevator when the elevator returns to the evacuation floor by the return command signal 5-1, and 6-2 indicates the main power supply of the single elevator control device 2. 6-3 is an inspection signal that is output when the inspection switch provided in the elevator single control device 2 is turned on, and this inspection switch is operated by maintenance personnel during inspection. This is a signal for notifying the private air traffic control device 1 that the aircraft is not subject to private air traffic control control. Reference numeral 6-4 indicates a failure signal output when the elevator operates when a failure occurs.

A conventional device having such a configuration will be explained with reference to the time chart shown in FIG. When the power purchase power supply is normally supplied, the power purchase detection relay operates and its a contact 3-a is closed, and normal elevator control is performed. When the electricity purchase power source experiences a power outage, the electricity purchase detection relay becomes inoperable and its a contact 3-a opens.

After a while, the private power generation equipment will start operating and supply the private power source. Therefore, the private power generation detection relay operates, and its a contact 3-a closes to notify that private power generation has started. As a result, private power generation control device 1
enters self-start control operation (Fig. 5 f), and this operation mode is each elevator's individual control system! Automatically enters by detecting the private power supply mode signal 5-2 on the 28-2c side,
Each elevator control device 28 to 2c controls the car to stop at the position at the time of power outage until it receives a private generation control signal.

When entering the private air traffic control, the private air traffic control control device 1 first gives a private air traffic control signal only to aircraft A. Then, the single elevator control device 2a of this car A controls the operation of the car so that it returns to the evacuation floor, and when the car returns to the evacuation floor and opens the door,
The elevator single control device 2a of the unit outputs a return completion signal 6-1 to the private generation control control device 1 and stops the operation (
C) in Figure 5.

Upon receiving the return completion signal 6-1, the private departure control device 1 then gives a private departure control signal only to the B car.6 Then, the elevator single control device 2b of the B car returns the car to the evacuation floor. When the vehicle returns and opens the door, the vehicle stops operating and outputs a return completion signal 6-1 to the private departure control bag w1 (d in FIG. 5). Upon receiving this, the private air traffic control device 1 then gives a private air traffic control signal only to aircraft C. Then, the single elevator control device 2c of this car No. C controls the operation of the car so that it returns to the evacuation floor, stops the operation when the car returns and opens the door, and sends a return completion signal 6-1 to the private departure control control device 1. (e in Figure 5).

Each elevator control device 28 to 2c outputs various completion signals according to their respective states.1 For example, when the main power source of the elevator control device is cut off, a power off signal 6-2 is output. If the elevator is under inspection, an inspection signal 6-3 is output, and if the elevator is out of order, a failure signal 6-4 is output, so that the status of each elevator can be grasped. Therefore, when such a signal is output and the aircraft is not subject to the private generation control control, the above-mentioned return command is given to the aircraft other than the non-target aircraft to cause the aircraft to return home.

When all units subject to private emission control control have returned home, the command for private generation control operation is completed (f in Figure 5), and then a private generation continuation operation command is issued to the predetermined elevator single control device of a specific unit. (g in Figure 5) to enable operation of only that machine and provide it for service.

In this way, the private-source controlled operation and the private-source continuous operation are carried out, and this is shown in a flowchart as shown in FIG. 6(a). That is, it is checked whether power purchase detection is on (sl), and if no, it is checked whether private generation detection is on (S2), and if this is also no, or if power purchase detection is on. S3 turns off the private engine control operation command.
), the private engine continuous operation command is turned off (S4). Also,
When the private engine detection is on, it is determined whether all the machines have returned home (S5), and if all the machines have returned, a private engine continuation operation command is issued (S6). If all units have not returned, a private start control operation command is issued (S7). Then move on to symbol 1.

The routine of symbol 1 is as shown in FIG. 6(b),
First, a private start control operation command is output to Unit A, so it is determined whether Unit A has returned to the evacuation floor (S
71), if it has not yet returned, the completion signal is turned on when the A-car returns to the evacuation floor (S72).

Then, check that the Unit A evacuation floor return completion signal is on (573), and if the Unit A evacuation floor return completion signal is indeed on, set the Unit A completion determination flag 574).
), turn off the completion judgment for all units and return to symbol 2 (
S75). If the answer is NO in S73, the completion determination for all machines is turned off and the process returns to symbol 2 (S75).

In S71, if the completion determination flag for Unit A is set, the process proceeds to S76, where a private start control operation command is output to Unit B, so it is determined that Unit B has returned to the evacuation floor, and any unfinished operations are performed. When returning, turn on the completion signal when Unit B returns to the evacuation floor (S77), and confirm that the Unit B evacuation return completion signal is on (s7g).
If the car number evacuation floor return completion signal is indeed on, set the car B completion determination flag (579), turn off the completion determination for all cars, and return to symbol 2 (S75). S78
If the answer is NO, the completion determination for all machines is turned off and the process returns to symbol 2 (S75).

In S76, if the completion determination flag for Unit B is set, the process goes to S80, where a private start control operation command is issued to Unit C, so it is determined whether Unit C has returned to the evacuation floor. If the vehicle has not yet returned, the completion signal is turned on when the C vehicle returns to the evacuation floor (s81). And this C
Please confirm that the unit evacuation floor return completion signal is on.582),C
If the car number evacuation floor return completion signal is indeed on, set the car C completion determination flag (583), turn off the completion judgment for all cars, and return to symbol 2 (s75). s82
If the answer is NO, the completion determination for all machines is turned off and the process returns to symbol 2 (s75). Also, in s80, C
If the return to the evacuation floor of the unit is complete, return to symbol 2.

FIG. 7 shows a flowchart of the operation of the elevator single control device under private power generation control. That is, it is checked whether the power purchase detection relay is on (all), and if it is on, there is no abnormality in the power purchase power source, and this routine is exited.

In sll, if it is off, it is checked whether the self-generated detection relay is on (s12), and if it is not on, there is no power, so this routine is exited. If it is on in s12, it means that the power source has been switched to the privately generated power source, so it is checked whether the power source for the own elevator is off (s13). If the power is off, the output of the power off signal is turned on (s14), and this routine exits.

If it is off in s13, check whether the inspection switch for the own elevator is on (s15) - Then, if the switch is on, it means that inspection is in progress, so output the inspection signal to on (516), and exit from this routine. .

If it is off in s15, it means that the elevator is not being inspected, and then it is checked whether the own elevator is out of order (s17).

This can be obtained, for example, from the status information of a watchdog timer that monitors the functions of a computer constituting the single elevator control device. If there is a failure, the failure signal is outputted and turned on (518), and this routine exits. If there is no failure in s17, it is checked whether the return command signal has been turned on (s19). That is, it is checked whether a return command has been given to the own aircraft. Then, if the return command signal is not turned on, this routine is exited. If the return command signal is turned on in s19, it means that the return command has been given to the own aircraft, so the return operation in the private departure control operation is started (sho). Next, it is checked whether the evacuation floor has arrived or not (s21), and if the evacuation floor has not arrived, this routine exits. If the evacuation floor has been reached, the return completion signal is turned on at the end of the return operation (sll, 523), and this routine is exited.

By executing the above steps, the return drive will be performed.

(Problems to be Solved by the Invention) As described above, in the private start control operation of the elevator system, a return command is given to a plurality of elevators in a predetermined order, and the evacuation and return operation is performed one by one. At this time, if the elevator is out of order, under inspection, or out of service, a signal is sent to notify the elevator, so the next elevator in the order receives the command for return operation.

In this way, a plurality of elevators are operated one by one to return to the evacuation floor, except for those that are out of order, undergoing inspection, or out of service. Once everything has been completed, continuous operation using private power will begin.

However, the original purpose of private power generation control operation is to switch the elevators that were in operation at the time of power purchase to limit the number of elevators from power purchase to private power generation (controlled capacity).

For this reason, for example, in this example of conventional privately operated air traffic control, for passengers who were on board C, which was the last to return to the evacuation floor, if Unit C became a continuously operated privately operated unit, it would be five destinations ahead. The floor is at the top of the building, and just as Habo arrives, the private engine control system will take him to the evacuation floor, whereupon he will be able to continue operating the private engine to reach his destination floor. Furthermore, passengers from elevators A and B, which had arrived earlier, were unloaded and waiting on the evacuation floor, and they boarded elevator C, which continued to operate. As mentioned above, the passengers who were riding in the elevator when switching from purchased power to private power generation were immediately taken to the evacuation floor and had to board the elevator again in crowded conditions, causing mental distress. Become. In addition, it is good for passengers who are brought to the evacuation floor and are able to immediately board the continuous operation aircraft (in this example, aircraft C) and go to their destination floor, but there are many passengers who are in a hurry. Passengers who missed boarding were forced to gather on the evacuation floor, causing even more mental pain.

The present invention prioritizes rescuing passengers trapped in cars until the number of elevators reaches its capacity (one car in this example) when switching from purchased power to private power generation. Therefore, the elevator is returned to the evacuation floor according to the private evacuation control control, and when the number of remaining elevators reaches 4N elevators on the remaining m evacuation floors within the self-emission capacity of the elevator, one elevator will return to the evacuation floor. Immediately, the private engine continuation operation number was designated and the private engine continued operation was started, thereby alleviating the mental suffering of the passengers in the elevator car and moving the passengers to the evacuation floor. When switching from purchasing power in the building to in-house power generation, it is possible to avoid crowding on the evacuation floor due to the collection of electricity, and at least as early as the time required for the final nilevator to return to the evacuation floor. The purpose of the present invention is to provide an elevator control device that eliminates confusion.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. In other words, the elevator control is equipped with a private departure control function that allows a group of elevators in operation to return to the evacuation floor in sequence by giving a return command to each elevator one by one when the elevators are in operation using a privately generated power source. In the apparatus, a determining means for determining return completion for the response elevator, a counting means that operates and counts when the return completion determining means makes a return determination, and a count value and a preset self-generation capacity of the elevator. means for comparing the switch value set to the number of elevators commensurate with the number of elevators and the number of elevators under the same private generation control, and according to the count value, when the number of unreturning completed elevators falls within the private generation capacity, the private generation control control is carried out. It is provided with a means for indicating completion, and a means for outputting a privately generated continuous operation command to subsequent unreturning elevators (excluding elevators that are out of order or under inspection).

(Function) In such a configuration, in the event of a power outage of the purchased power source, the in-house power generation equipment is operated, and power is supplied from this, and
A return command is given to a plurality of elevators in operation one by one as a group, and the elevators responding to the command are sequentially returned to the evacuation floor. At this time, the return completion determining means determines whether the response elevator has completed the return. When the return completion determination means makes a return determination, the counting means operates to sequentially count the number of return completion elevators. It depends on the difference between this count value and the number of elevators under the same private generation control.

When the number of unreturning elevators becomes equal to or less than a preset value based on the elevator's private generation capacity, the private generation control completion means operates, and issues a private generation continuation operation command to the remaining elevators that have not returned to the evacuation floor. The remaining elevators will continue to operate without resulting in a single evacuation, which will not only prevent congestion by concentrating passengers on the evacuation floor, but also allow the passengers who were on the remaining elevators to Not only does the mental pain caused when switching from buy to own be alleviated, but also the start of continued operation is faster, so the confusion at the time of the switch quickly subsides.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2.

In the conventional Fig. 3, 5-1 to 5-4 are private power generation control signals 5, and among these, 5-1 is a power purchase detection relay that amplifies the a contact signal of the power purchase detection relay that is turned on when power is purchased. The electric power supply mode signal 5-2 is a private power generation supply mode signal obtained by amplifying the a contact signal of the private power generation detection relay that is turned on during private power generation. Further, 5-3 indicates each elevator single control device 2 in the order determined by the private generation control control device 1 during private generation control automatic operation.
This is a return command signal given to aircraft No. 8 to 2C for returning to the evacuation floor.1For example, it is first output to aircraft A,
When the A car returns to the evacuation floor, the output will be sent to the B car in the same order as above. 5-4 is a continuous operation command for private generation control, and when the number of remaining elevators that do not return reaches the private generation capacity, the command is issued to only one predetermined number of elevators.Here, for example, This is given to the single elevator control device of Unit C.

6-1. 6-4 is a completion signal 6, and 6-1 is a return completion signal output from the single control device of the elevator when the elevator returns to the evacuation floor by the return command signal 5-1. . Further, 6-2 is a power off signal that is output when the main power of the elevator single control device 2 is cut off;
-3 is an inspection signal that is output by turning on the inspection switch provided in the elevator single control device 2, and by operating this inspection switch at the time of inspection, a maintenance worker can indicate that the unit is not subject to private generation control control. This is a signal to notify the private air traffic control device 1 of this fact. Reference numeral 6-4 indicates a failure signal output when the elevator operates when a failure occurs.

This apparatus having such a configuration will be explained with reference to the time charts shown in FIGS. 1 and 2. When the power purchase power supply is normally supplied, the power purchase detection relay operates and its a contact is closed, and normal elevator control is performed. When the electricity purchase power source experiences a power outage, the electricity purchase detection relay becomes inoperable and its a contact opens. Then, after a while, the private power generation equipment will start operating and supply power for private generation, so the private power generation detection relay will operate and its a contact will close, indicating that private power generation has started. As a result, the private generation control device 1 enters private generation control operation. This operation mode is automatically entered by detecting the private generation supply mode signal 5-2 on the side of each elevator single control device 2, and each elevator single control bag [12 has a power outage of the car until the private generation supply control signal 5-2 is received. control to stop at the current position.

When entering the private air traffic control, the private air traffic control control device 1 first gives a private air traffic control signal only to aircraft A. Then, the single elevator control device of this unit A controls the operation of the car so that it returns to the evacuation floor, and when the car returns and the door is opened, the single elevator control device of the unit A sends a return completion signal to the private departure control control device 1. 6-1 is output and operation is stopped. Upon receiving the return completion signal 6-1, the private air traffic control device 1 then gives a private air traffic control signal only to aircraft B. Then, the single elevator control device of this No. B elevator controls the operation so that the car returns to the evacuation floor, and when the car returns and the door is opened, the operation is stopped, and the return completion signal 6 is sent to the private departure control control device 1. −
Outputs 1. I gave the commands as I said and controlled the operation to return to the evacuation floor.

Each elevator control device 2 outputs various completion signals depending on its status. For example, when the main power of the elevator control device is cut off, the power off signal 6-2 is output for inspection. If the elevator is in the middle, an inspection signal 6-3 is output, and if the elevator is out of order, a failure signal 6-4 is output, so that the status of each elevator can be grasped. Therefore, when such a signal is output and the aircraft is not subject to private generation control control, the above-mentioned return command is given to the aircraft other than the non-target aircraft to cause them to return home.

Among the elevators subject to private generation control, the number of elevators that exceed the private generation capacity will be sequentially returned to the assigned evacuation floor and stopped, but when the number of elevators that have not returned is within the number of private generation capacity, the private generation control will be activated. Once completed, a command to continue operating the private generator will be given to the designated unit to make it operational and ready for service.

In this way, private power generation control operation and private generation continuous operation are carried out.
It is as shown in the figure.

In other words, in FIG. 1, similar to FIG.
F clears the count B of the number of return completed elevators to 0 at the time of private departure control by 88 in the flow.

Next, when private power generation detection is turned ON, private power generation control operation begins.

It is determined whether all the machines have returned home (s5 in Figure 1).If all the machines have returned, a command to continue operating the private engine is issued (s6 in Figure 1). If all units have not returned, issue a private start control operation command (s7 in Figure 1). Then move on to symbol 1.

In the case of this embodiment, the routine of symbol 1 is as shown in Fig. 2.The number of remaining elevators (A-B) and the number of elevators C corresponding to the private generation capacity are compared at s70, and first, the number of elevators in car A is On the other hand, since a private generation control command is output,
Determine whether the return to the floor has been completed to avoid Unit A (s73),
Turn on the completion signal when Unit A returns to the evacuation floor (
s74), and.

The count of the number of returned vehicles is set to B=1.0 The same procedure is performed for the B-th vehicle, and when the B-th vehicle completes its return, the number of returned vehicles is set to B=2.

Next, in s70, the number of remaining elevators (A, -B=3-
2=1) is the number of elevators corresponding to the private power generation capacity C=
1, and the completion determination for all machines is turned ON in s84.

In Fig. 2, when the completion judgment for all units is turned ON, Fig. 155
It is assumed that all units have returned home, and s6 is turned on.
Then, when the private power generation control is completed, a continuous operation command is output to the pre-designated elevator C, and Unit C starts continuous operation on the spot without returning to the evacuation floor.

In this way, this device operates the private power generation equipment during a power outage at the power source, thereby receiving power supply and giving a return command to a group of multiple elevators in actual operation one by one. As a result, the elevators that respond to the command are returned to the evacuation floor one by one.At this time, the number of elevators that have returned (including elevators that are undergoing inspection for failures) is counted, and the remaining elevators are calculated based on this count value and the number of elevators in actual operation. By calculating this value and comparing it with the number of elevators commensurate with the private generation capacity, when the number of remaining elevators becomes less than the private generation capacity, private generation control is considered complete and the remaining elevators are immediately switched to continuous operation. .

〔Effect of the invention〕

As a result of the above, the remaining passengers in the elevator are:

- Not only can you go to the destination floor without being taken to the evacuation floor by your carrier, which reduces the mental pain when switching from buying to owning, but it also allows you to start continuous operation earlier than before, so you can It is possible to provide an elevator control device in which confusion quickly subsides.
