DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A gate opening / closing management system according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a gate opening / closing management system according to the present invention. 1
Is a call unit for talking with the control room, etc., 2 is a camera unit for photographing a visitor and outputting a video signal, and 3 is a timer for measuring a preset gate opening time. 10 is a key input unit for inputting a telephone number and a personal identification number, 12 is a display unit for displaying input numbers, and 11 is a pre-stored personal identification number and a parking place number in use. Is a storage unit, 13 is a determination unit that determines whether or not the input number string and the stored personal identification number are the same, and 4 is a control unit that controls each unit. As described above, the gate unit is configured by the respective units of the call unit 1 to the control unit 4. Reference numeral 6 is a gate that opens and closes based on a gate control signal 16 output from the gate machine. Reference numeral 7 is a private branch exchange for connecting and connecting a telephone line. Reference numeral 8 is a PB telephone installed in the control room. 9 is installed in the control room,
It is a display monitor that displays an image of a visitor sent and an unused parking lot number on-screen.

The operation will be described. FIG. 2 is a first flowchart showing the operation of the gate opening / closing management system according to the present invention. For example, the resident inputs the personal identification number from the key input section of the gate machine (STP1). It is determined whether or not the stored personal identification number and the inputted number sequence match (STP2). If they match (YES), the gate control signal 16 is output to open the gate (STP3). The timer unit 3 measures the gate opening time, and when the predetermined time has elapsed, outputs the gate control signal 16 and closes the gate (STP4). If they do not match (NO), the number of times the personal identification number has been entered from the key input section is counted (STP5). As for the number of times of inputting the above-mentioned personal identification number, for example, an erroneous input of up to 2 times is recognized
If it is a mischief or a crime, it judges whether or not it is the third time (STP6), and if the number of times is 1 or 2 (NO), waits for the next input (to STP1). If the number of times of disagreement is 3 (YES), a notification is sent to the management room to prevent mischief or crime (STP7).

FIG. 3 is a second flowchart showing the operation of the gate opening / closing management system according to the present invention. For example, when the visitor dials the telephone number of the management room, which can be known from the display of the gate machine, from the key input unit 10 of the gate machine, the private branch exchange 7 connects the line to the PB telephone 8 in the management room, and Call the PB telephone 8 (STP1
0). After the PB telephone 8 in the control room is off-hook, the camera section 2 is activated (STP11). The visitor calls the manager to open gate 6 (STP12).
The manager listens to the visitor's name, purpose of visit, etc., and looks at the visitor's face, figure, etc. on the display monitor 9 to confirm that he or she is not a suspicious person, and displays an on-screen unused parking place. Check the number (STP13). During the call, the number of the parking place to be used is instructed to the visitor by the PB telephone 8, and for opening the gate, for example, by pressing the # key and pressing the PB signal, the gate is opened. An instruction is given, and then the number of the parking place instructed to the visitor is input (STP14). The gate machine receives the PB signal, outputs the gate control signal 16 of "open" to the gate, stores the number of the parking place in use, and starts the measurement of the predetermined time by the timer unit 3 (STP15). .. When the predetermined time has elapsed, the gate control signal 16 of "close" is output to the gate to close the gate (STP16). Stop the operation of the camera unit 2 (STP17
). In addition, when the visitor leaves the parking lot, the procedure similar to the above case is executed, and after the visitor confirms the visitor,
Open the gate and enter the vacant parking place number P
Input from telephone B, and the gate machine stores the number of the vacant parking place.

[0009]
