室者がいるときはステップ６１に戻る。The operation of the apparatus shown in FIGS. 1 and 2 having the above structure will be described with reference to the flowchart shown in FIG. The first person enters the card 24 in which the identification code is recorded.
When it is inserted into the entrance card reader 10 as a card reader, the process proceeds from step 50 to step 51, and the central control circuit 1
Reference numeral 5 determines whether or not the card 24 has been inserted into the entry card reader 10. The central control circuit 15 judges whether or not the code code read by the entrance card reader 10 is the permissible code given to a regular employee (step 52), and the permissible code.
If not, the process returns to step 50. In the case of the permissible code, the process proceeds from step 52 to step 53, and the person name corresponding to the code code and the time of operation are recorded. Next, in step 54, a timer which is built in the central control circuit 15 and is program-controlled is activated, and in step 55, an unlock signal is generated from the central control circuit 15 to the lock control circuit 11 for a certain time. Therefore, a person who enters the room can open the door 18. In step 56, the central control circuit 15
Determines whether the timer has counted a certain period of time. If the fixed time has not passed, the central control circuit 1
Reference numeral 5 determines whether or not the door 18 is opened by a signal from the door switch 20 which is operated when the door 18 is opened. If the door 18 is not opened, the process returns to step 56. When the door 18 is opened in step 57, the entry / exit sensor 21, such as an infrared sensor for detecting the passage of a person, is used in step 58 to determine whether or not the person has entered the room. When the occupants pass, the central control circuit 15 adds or subtracts the number of occupants. When the door 18 is not opened in step 57, and when the room occupant does not pass in step 57, the process returns to step 56. If no occupants pass in step 58, the process jumps to step 60. Step 60
It is determined whether or not the door 18 has been opened in step S1, and if it is opened, the process returns to step 58, and if it is not opened, the process proceeds to step 61 and a lock signal is generated. Also, step 5
After a lapse of 6 hours, the process proceeds to step 62. When there is no input signal to the entry card reader 10 in step 51, it is determined in step 70 whether the time card reader 14 has an input signal. Time Car
If there is an input to the reading device 14, it is determined in step 71 whether or not the data is work attendance data. In the case of coming to the office in step 71, the number of people coming to work is added in step 72, and then the process proceeds to step 61. If there is no input signal to the time card reader 14 in step 70, it is judged in step 75 whether or not the person is an exit. This can be detected when the door switch 20 is in the off state and there is no signal from the entry card reader 10 and the entry / exit sensor 21 allows the exiting person to pass by. When there is no leaving person in step 75, the process proceeds to step 76, the number of persons entering and leaving the room is subtracted, and then the process proceeds to step 76. When the data is not the work leaving data to the time card reading device 14 in step 71, it is determined whether or not the work leaving data. here,
When it is determined that the employee has left the company, the number of employees who have left the company is subtracted in step 74. When it is determined that the employee has not left the employee in step 73, the process proceeds to step 62. Then, in step 62, the central control circuit 15 determines whether or not there is a person in the room. When there is a person in the room, it is determined in step 65 whether or not the equipment operation is suppressed. If the equipment operation is suppressed, after releasing the equipment control signal in step 66,
Returning to step 50, if the equipment operation is not suppressed in step 65, the procedure returns to step 50. Step 62
If the central control circuit 15 determines that there is no occupant, the central control circuit 15 determines in step 63a that there is a re-entry person based on the data from the time card reader 14 and the actual number of occupants. Judge whether to do or not. When there is no re-entry person, an equipment control signal is generated in step 63 and an unlocking signal for the door 18 is generated (step 6).
After 4), the process returns to step 50. When there is a person who has re-entered the room in step 62, the timer is activated (step 67) in step 67, and it is determined in step 68 whether there is a person who has entered the room. When there is no person in the room, it is determined in step 69 whether or not a predetermined time has elapsed. When the predetermined time has not elapsed, the process returns to step 68, and when the predetermined time elapses, the process proceeds to step 63. If there is a person in the room in step 68, the process returns to step 61.
