Abstract

PURPOSE:To prevent an operation neglect and to simplify equipment by providing the destination register checking circuit stopping the service of an elevator into the unit guard area based on a guard starting signal, in the elevator provided with a guard start command device in the unit guard area of each floor. CONSTITUTION:When a guard start command is placed with a guard start command device 2 being actuated, the signal from a sensor 1 is transmitted to a centralized monitoring panel 3a and a guard state becomes. Simultaneously a guard start signal is transmitted to a destination register checking circuit 4. So an elevator control circuit 6 is actuated so as to stop the service of elevator to the story floor of the unit guard area. Consequently the invasion of a questionable person can surely be prevented without any special large sized equipment.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator control system, and more particularly to an elevator control system that prevents elevators from intruding into a guarded area.

[Prior Art] Generally, when a hall call is registered, an elevator responds to the call and moves to a desired floor by operating a destination floor registration button provided inside the car.

By the way, in recent buildings, especially in tenant-based buildings, security guards are not stationed on the floor corresponding to the entrance floor.
Instead, a system is adopted in which security devices are provided for each tenant and these security devices are centrally monitored in a predetermined management room. Therefore, a suspicious person can use the elevator to enter the destination floor without being criticized by anyone.

Therefore, a non-stop switch is installed on the elevator car operation panel or in the landing area to prevent the elevator from operating to that specific floor, and the elevator operation device disclosed in Japanese Patent Application Laid-open No. 62-46881 is used to prevent suspicious traffic from occurring. Measures were taken to prevent people from entering.

[Problem to be solved by the invention] However, the former prior art has troublesome operation]
It is difficult to completely prevent intrusion by suspicious persons, as users sometimes forget to operate the system due to lack of security. In addition, the latter requires large-scale equipment, making the configuration complicated and expensive.

The present invention solves the above-mentioned problems, and its purpose is to provide an elevator control method that can reliably stop service to a specific floor when desired and can be constructed at low cost. It is in.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides, based on a signal of the security status of the unit security area, an elevator service to the floor of the unit security area from which this signal was issued. It is characterized by being made to stop.

[Function] Since the elevator control system according to the present invention has the above-described configuration, if the security device is activated when the users of each floor leave and the elevator is in an unmanned state, the elevator is activated by the security state signal. , a command is issued to stop service to the floor in question, and the service is moved to the unmanned floor, which prevents forgetting operations due to the hassle of conventional operations, and does not require large-scale equipment. An inexpensive elevator control method that reliably prevents the intrusion of suspicious persons can be obtained.

[Example code] Embodiments of the present invention will be described below with reference to the drawings.

In the illustrated building, a unit security area is formed on each floor, and each unit security area is provided with a crime prevention and disaster prevention sensor 1 that senses various signals, and a security start command device 2. This security start command device 2 issues a security start command for the unit security area by operating a key provided near the entrance of each floor or by inserting an ID card, or by locking the entrance door. At the time of day, for example during dispatch time, a release command is issued.

The security start command from the security start command device 2 is given to the destination registration prevention circuit 4 provided in the machine room 8 and the central monitoring panel 3a provided in the control room 3 via signal lines 5 and 7, and the security start command is sent to the destination registration prevention circuit 4 provided in the machine room 8 and the central monitoring panel 3a provided in the control room 3. The cancellation command from the command device 2 is similarly given to the destination registration blocking circuit 4 and the central monitoring board 3a.

Now, when a guard start command is issued by the operation of the guard start command device 2, the signal from the sensor 1 is sent to the central monitor 13a to enter the guard state, and at the same time, the guard start signal is given to the destination registration blocking circuit 4. Then, the elevator control circuit 6 is activated to stop the elevator service to the floor of the unit security area. For example, if the last person to leave the sixth floor locks the entrance/exit door, the security start command device 2 is activated, sends the signal from the sensor 1 to the central monitoring panel 3a, enters the security state, and the destination registration prevention circuit 4 prevents registration to the 6th floor using the destination floor registration button. Therefore, after the last person leaves, the elevator cannot be used to go to the 6th floor, thereby preventing intrusion by suspicious persons.

However, when it comes to the established time, such as the dispatch time,
A cancellation command is given to the destination registration blocking circuit 4 by the security start command device 2, etc., and the registration of the 6th floor using the destination floor registration button becomes possible, and the elevator service is resumed as usual.

[Effects of the Invention] As explained above, the present invention includes a destination 'i18 blocking circuit that stops elevator service to a predetermined floor based on a signal for placing a security state on that floor. An elevator control method that prevents forgetting to operate due to bothersomeness and does not require large-scale equipment as in the past, reliably and inexpensively prevents intrusion by suspicious persons.
