Description

[Detailed Description of the Invention] [Industrial field of application] This invention is designed to prevent elevators from being stopped on unmanned floors in facilities where high security needs such as intelligent buildings are required.
The present invention relates to an elevator non-stop control device that prevents a suspicious person from entering an unmanned floor.

[Conventional technology]

Conventionally, in a security system such as a building, for example, a security area is configured in units of rooms and tenants, and when working hours are over, individual security keys, numeric keypads, card readers, etc. are used to set security status, I was canceling it.

In particular, facilities such as intelligent buildings equipped with advanced information and communication functions have stricter security needs and seeds. That is, to exemplify a security method that is generally implemented, when all departments and tenants existing on a certain floor leave, the main device of the security system indicates that all the security areas of the floor are in the security state. Detect
A method of controlling the elevator control panel so as not to stop even when the destination button on the floor is pressed in the elevator cage is adopted. This elevator non-stop measure is released when the security status is released in any one of the departments and tenants on the floor, and the elevator can be stopped on the floor. On the other hand, while the floor is set to security status, if an abnormality detection sensor installed in each security area of the floor issues an alarm, this alarm signal is sent to the security center of the security company via the communication part of the security system. According to the report, security guards rushed to the building to investigate the cause of the alarm signal.

[Problems to be solved by the device]

However, in the above-mentioned conventional security system, the security staff who rushed in response to the alarm signal must go to the security area on the floor where the alarm was issued, but the elevator does not stop on the floor, so use the stairs. It is necessary to reach the floor or release the security status of the security area using a master key or the like. In either case, it takes some time, and especially in the case of a high-rise building, it is practically difficult to use the stairs, and there is a risk that failure to prevent the spread of an abnormal situation such as a fire or an intruder may occur. .

This invention was made in order to solve the above problems, and in a facility having multiple floors, when all the security areas on a floor are in a guarded state and the elevator is not stopped on that floor, An object of the present invention is to obtain an elevator non-stop control device capable of promptly responding when an abnormal state occurs in a security area on the floor.

[Means for solving the problem]

Elevator non-stop control device according to the present invention, each security storage unit that stores the security state of each security area, each alarm storage unit that stores an alarm signal from each abnormality detection sensor provided in each security area, A floor security storage unit is provided to output a floor security signal when all security areas on the same floor are in a normal state and when the security status is activated, and to prevent the elevator from stopping on the floor due to this floor security signal. is there.

[Action]

In this invention, all the security areas on the same floor are in the security status and the elevators are not stopped on the floor, and the security status of any security area is released or When the abnormality detection sensor detects an abnormal state, the non-stop state of the elevator to the floor is released.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of an elevator non-stop control device, and FIG. 2 shows the configuration of a security system including this elevator non-stop control device. First, in FIG. 2, 1a and 1b are abnormality detection sensors installed in security areas a and b existing on the same floor, and 2a and 2b are security areas that switch security areas a and b to a security state or a security release state, respectively. The switch 3 is a remote device installed on the floor where the security areas a and b are present, 4,5
Is a remote device installed on another floor, 6 is an elevator non-stop control device installed in a disaster prevention center of the facility,
Reference numeral 7 denotes an elevator control panel, which monitors signals from the elevator cage 8 and controls its operation.

Further, in FIG. 1, 60 is a processing unit, 61 is an input unit, 62a,
62b is a security storage unit that stores the security status of each of the security areas a and b, 63a and 63b are alarm storage units that store the alarms from the security areas a and b, 64 is an AND gate, 65 is a NOR gate, 66 is the same A floor security storage unit 67 stores the security status of all security areas belonging to the floor, and an output unit 67.

Next, the operation of the above configuration will be described. The remote device 3 is installed on the floor where the security areas a and b are located. For example, it is assumed that the security area a has already finished working hours and all the staff have left, and the security switch 2a has set the security status. . In this case, this security setting signal is transmitted from the remote device 3 to
The elevator non-stop control device 6 is reached via 5 and the input unit
It is input to the security storage unit 62a via 61, and the security storage unit 62a stores the security state. Here, when the staff member in the security area b finishes his / her work and operates the security switch 2b to set the security area b in the security state when leaving the building, the security setting signal indicates that the remote devices 3 to 5 and the input unit 61 are set. It is input to the security storage unit 62b via the security storage unit 62b, and the security storage unit 62b stores the security state.
On the other hand, since the alarm storage units 63a and 63b have not received an alarm, the normal state is stored and no signal is output to the NOR gate 65. Therefore, the output of the NOR gate 65 is ON, and the signal is also output from the security storage units 62a and 62b, so the output of the AND gate 64 is also ON,
The floor security storage unit 66 stores that all security areas a and b belonging to the floor are in a security state. As a result, a floor guard signal is output from the floor guard storage unit 66 to the elevator control panel 7 via the output unit 67, and the elevator basket 8 does not stop on the floor.

When an abnormal situation such as a fire occurs in the security area a in such a state, the abnormality detection sensor 1a detects this and transmits a detection signal to the elevator non-stop control device 6 via the remote devices 3-5. This detection signal is input to the alarm storage unit 63a of the processing unit 60 via the input unit 61, and the alarm state is stored. An alarm signal is output from the alarm storage unit 63a to the NOR gate 65 and a display unit, a sound unit, a communication unit, and the like (not shown). Therefore, the output of the NOR gate 65 is turned off and the output of the AND gate 64 is also turned off, so that the floor guard signal from the floor guard storage unit 66 is not output and the elevator cage 8 stops on the floor via the elevator control panel 7. Come to do. For this reason, the guard who rushed in response to the alarm signal can use the elevator to rush to the floor and quickly deal with the abnormal situation. When the processing is completed and the alarm status is reset, the alarm storage unit
63a means that the normal state is stored, and the security storage unit 62
If the security status is stored in a and 62b, the elevator cage 8
Will not stop on the floor again. The term "not stop" means that even if the destination button on the floor in the elevator basket 8 is pressed, it is ignored and does not stop. Therefore, the elevator call button on the floor is valid, and the guard who has completed the above processing can press the elevator call button on the floor to call the elevator and normally exit the building.

By the way, when a person on a certain floor enters the building and the security status of any of the security areas a and b of that floor is released, the floor security signal of that floor is no longer output, so the elevator cage 8 stops at that floor. Like

In the above embodiment, when the elevator non-stop state is released, the elevator non-stop control device 6 does not output the floor guard signal.
You may make it the alarm signal from 63a, 63b input into an external device, and suppress the operation | movement by a floor guard signal by this external device. Further, in the above-mentioned embodiment, when the abnormal state is detected, the output of the floor security signal is stopped and the non-stop of the elevator to the floor is released. When the guide lights are turned off, they can be turned on by stopping the output of the floor security signal so that the security staff can assist the alarm site confirmation work.

[Effect of device]

As described above, according to the present invention, in a device that controls not to stop the elevator on the floor when all the guard areas on the same floor are in a guarded state, the abnormality detection sensor in any of the guarded areas on the floor. When an anomaly is detected, the non-stop operation of the elevator to the floor is released, and the guards who rushed to the anomaly detection signal can use the elevator to rush to the floor, and the suspicious person It is possible to swiftly cope with the intrusion of a car and the occurrence of a fire.
