Abstract

PURPOSE:To enable operational control with high efficiency and safety to equipments to be controlled by providing a counting means to count the number of persons in a room based on difference between the number of incoming persons and the number of outgoing persons. CONSTITUTION:A passage operating means 1 executes operation necessary for the passage of entrance and exit gates, which are respectively grounded, and outputs signals corresponding to entrance and exit to a counting means 4. The counting means 4 receives signals from the arbitrary passage operating means 1. Then, one unit is added to a counted result at the time of entrance and subtracted from the counted result at the time of exit. When the counted result of the counting means 4 is increased or made 0, a control means 2 is operated so as to control the operation of an equipment 3 to be controlled. Then, the operation of the equipment 3 to be controlled is controlled when the person enters the room through the arbitrary entrance and exit gate, where the passage operating means 1 is set up, and the outgoing person is the final outgoing person. Thus, to terminal equipments, the operational control can be executed with the high efficiency and safety.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an entrance/exit control device installed at an entrance/exit gate, which operates the entrance/exit gate and also controls the operation of the @Saku IIJri. 2. Description of the Related Art A conventional device of this type includes an entrance/exit operating means 1 for operating an entrance/exit as shown in FIG.
For example, when an entrance operation is performed at the time of entrance, the control means 3 operates the controlled equipment 2 via the control means 3, and when exiting the gate, the control means 3 controls the operation of the controlled equipment 2. When this is done, operations such as stopping the controlled device 2 are performed via the control means 3.

Problems to be Solved by the Invention However, in the above structure, when multiple people try to enter and exit from multiple entrances, the person exiting the gate must follow other entrances if he or she is not the last person exiting the gate. If you are the last person to exit the gate, do not use the designated entrance/exit gate where the entrance/exit control device is installed. This was not only an inconvenience, but also an important issue from a safety perspective. Means for Solving the Problems In order to solve the above problems, the entrance/exit management device of the present invention has the following features:
a plurality of entry/exit operating means; and a counting means for counting the difference between those entering and exiting in accordance with signals from the input/output operating means;
It consists of a control means that controls the operation of the controlled equipment according to the counting results of the counting means. Operation The present invention is installed in a space having a plurality of entrances and exits with the above-described configuration, and functions as follows. The entrance/exit operating means performs the operations necessary for entering/exiting each of the installed entrance/exit gates, and outputs signals corresponding to entry/exit to the counting means. The counting means receives a signal from the arbitrary entrance/exit operating means, adds one unit to the counting result when entering the gate, and subtracts one unit from the counting result when exiting the gate. The control means acts to control the operation of the controlled equipment when the counting result of the counting means increases and when it becomes 0, and when entering at any entrance/exit where the entrance/exit operating means is installed,
The operation of the controlled equipment is then IQIed when the person leaving the gate is the last person leaving the gate. Examples Examples of the present invention will be described below with reference to the drawings. FIG. 3 is an explanatory diagram for controlling indoor lights in a room with n entrances and exits, where la to 1n are the entrance/exit operating means, 2 is the control means, and 3 is the controlled equipment. A certain room light, 4, is a counting means, and when a person entering the room operates the entrance/exit gate operating means l from outside at any entrance/exit J'' when entering the room, the said entrance/exit gate operating means l unlocks the electric lock and , sends an entry signal to the counting means 4.The counting means 4 adds 1 to the difference between the number of people in the room and the number of people leaving the room,
Send the result to control means 2. When the control means 2 detects an increase in the number of people in the room based on the signal from the counting means 4, it turns on the room light. When the person leaving the room operates the entrance/exit operating means 1 from within the room at any entrance/exit, the entrance/exit operating means 1 unlocks the electric lock and sends an exit signal to the counting means 4. The counting means 4 subtracts 1 from the difference between the number of entrants indicating the number of people in the room and the number of exiting students, and transmits the result to the control means 2. When the control means 2 detects that the signal from the counting means 4 means that the number of people in the room has become zero, it turns off the interior light 3. In the above embodiment, an electric lock operated by a human being was used as the entrance/exit operating means l, but the invention is not limited to this, and it goes without saying that a device that automatically counts the number of people entering and exiting may also be used. Effects of the Invention As described above, the entrance/exit management device of the present invention has a plurality of entrance/exit operating means, the counting means counts the entry/exit by operating any of the entrance/exit operating means, and the control 1D means controls the operation of the controlled equipment according to the counting results, and therefore controls the operation of the controlled equipment only for all entrances and final exits for multiple entrances and exits from multiple entrances and exits. Therefore, it is possible to control the operation of controlled equipment efficiently and with high safety.
