Figure 4 shows an embodiment of the FM transmission and reception circuit of Figures 2 and 3, which is possible with a well-known FM transmission and reception circuit. Therefore, a detailed description of the circuit configuration and its operation relationship is omitted.

5 is a view for explaining an embodiment of the enable means 230 of the present invention, the detection area ADI of the first outer human body detection sensor 231 and the detection of the second outer human body detection sensor 232. The area AD2 is set as shown in the figure, and the detection area AI1 of the first inner human body detection sensor 233 and the detection area AI2 of the second inner human body detection sensor 234 are shown. Therefore, when approaching the external sensor door is first detected by the first outer human body detection sensor 231 and then the second outer human body detection sensor 232 it can be seen that a person is approaching. The first and second inner human body detection sensors 233 and 234 detect the approach of the human body inside the door.

The operation of the present invention configured as described above will be described.

First, the secret code of the legitimate user is given to the remote response master key 100 and the self-responsive electronic switch 20, respectively. The legitimate user will be given a user secret code for each person who is allowed access to the door installed in the self-responsive electronic switchgear 200, and the user of the person who owns the remote response master key 100 to the remote response master key 100. Only the secret code is recorded, the self-responsive electronic switch 200 is all the secret code of all the users allowed to enter. On the other hand, the remote response master key 100 stores each unique code of a plurality of self-responsive electronic switch 200. When a user inputs a user secret code through the input means 110, the control means 120 compares and determines whether the input secret code matches the stored secret code and sets the system to the enabled state. In this way, the remote response system in the enabled state is enabled. As described above, the remote response master key 100 in the enabled state is switched on so that power is supplied to the transmission and reception means 140 and 150 so that transmission and reception of signals is possible. When the user approaches the door after enabling the remote response master key 100, the self-responsive electronic switch 200 by the human body detection sensor 231 detects and enables the system. That is, the microcomputer 220 turns on the switch 221 to supply power to the transmission and reception means 250 and 260. Subsequently, the serial data read out from the unique code recorded in the storage means 240 is FM-modulated by the transmitting means 250 via the serial-to-parallel conversion unit 250a to transmit the call signal to the public. Send it out. The remote response master key 100 demodulates the call signal received through the receiving means 140, converts the demodulated serial data into parallel data through the serial-to-parallel conversion unit 140a, and converts the converted parallel data into the microcomputer 120. Is entered. If the inputted unique code is one of a plurality of unique codes stored in the storage means 130, the microcomputer 120 reads the user secret code and the door open command code to read the serial-parallel conversion unit 150a and the transmission means 150. Send a command signal to the air.

The self-responsive electronic switch 200 compares the user password code inputted through the receiving means 260 and the serial-to-parallel conversion unit 260a with a plurality of stored user password codes, and recognizes that one of them is a legitimate user. Then, the driving device 270 is driven by driving the driving circuit 270b through the interface circuit 270a in response to the signal of the second outer body detection sensor 232. For example, when the command signal is a door open command, the solenoid is operated to automatically open the door. The door open time and the user secret code are stored in the storage means 240 by the internal clock of the microcomputer 200. When the user passes through the open door and leaves the area of the second inner detection sensor 234, the door is closed and the door is closed through the motion detecting means 280 to detect whether the door is completely closed. An alarm sound is generated through the neck portion 290. Therefore, when the door is not locked due to a malfunction, the user may recognize through the alarm sound and manually operate or check a malfunction state.

Here, the user secret code may be set to 4 digits, for example, and the command may be set to a combination of a special key and a numeric key. If the input secret code matches the previously input secret code (step 403), the system becomes enabled and can transmit and receive (step 404). The command is decoded to determine a given mode (step 405), and if it is an update mode, update processing of the user secret code is performed (step 406). In confirmation mode, the user secret code and command code are read (step 407). The command signal is sent (step 408), and the call signal is input (step 409). It is determined whether the unique codes of the call signal match (step 410), and if it matches, the received data is stored (step 411), the reception completion of the reception data is checked (step 412), and the reception data is displayed when the reception is completed. Display through means 160 (step 413). In operation mode, input a call signal (step 414) and determine whether the received unique code matches a previously stored unique code (step 415), and if it matches, read the user secret code and door open command code (step 416). Send a command signal (417) and terminate the system.

8B is a flowchart showing a control program of a preferred embodiment of the self-responsive electronic switchgear. In FIG. 8B, the program initializes the system when the initial power is turned on (step 501), checks the enable by the human body detection sensor (step 502), and turns the system on when the human body access is enabled. It is possible to transmit and receive a signal (step 503). Subsequently, a call signal carrying a unique code is transmitted (step 504), and a check is made (step 505). If no signal is received, the number of transmissions of the call signal is counted (step 506). If the number of transmissions is 5 or more times without the received signal, a warning is issued (step 507) and the program ends. If the predetermined number is five or more times, a warning is issued (step 507) and the program ends. If the reception of the signal in response to the call signal is checked within a predetermined number of times, the command signal is input (step 507), and the user password code determined in the command signal is determined (step 509). Detox. The mode according to the decrypted command is determined (step 511), and in the update mode, the recorded user secret code is updated with a new secret code (512) and ends. In the confirmation mode, the access status check data is read out (step 513), and then the data is sent out (step 514), and data transmission is checked for completion (step 517). In other words, if the door is not completely closed, an alarm is issued (step 512). If the operation is normal, the current time and the input user secret code are recorded (step 522) and the program is terminated.

As described above, the door opening and closing device of the present invention is automatically connected by a mutual response between the portable remote response master key and the self-responsive electronic switch when the user walks and accesses multiple doors without any operation or manipulation with a single user secret code input. It is very convenient because it is opened and passed through, so it is locked again. In particular, the user is in a state in which both hands are inconvenient, that is, it is more convenient for people with disabilities or handicapped.

In addition, the remote response master key can check the operation status of each electronic switch, so it is possible to check the current status of the person passing through the door where the electronic switch is installed, so that the access control can be more effectively controlled.
