In the personnel retention alarm circuit 200, because the human body induction switch KHOften an infrared sensitive switch. Human body induction switch KHThe principle of (1) is as follows: when a person enters the sensing range, the infrared sensor detects the change of the infrared spectrum of the human body, and the human body sensing switch KHAutomatic connection; human body induction switch K for preventing human body from leaving induction rangeHWill be continuously on; after the person leaves, the human body inducts the switch KHAnd automatically disconnecting.
In the personnel entrapment warning circuit 200, the second coil K2aAnd a second normally open contact K2cA normally open relay is formed. When the second coil K2aWhen electrified, magnetic force is generated, so that the second normally open contact K2cClosing; when the second coil K2aWhen no electricity is available, the second normally open contact K2cThe reset is off. Second timer KT2aAnd a first normally open contact KT1bAlso forming a time relay when the second timer KT2aAfter the timing according to the first preset time is finished, the first normally open contact KT1 is enabledbIs closed when the second timer KT2aOut of operation, or when the second timer KT2aWhen the out-of-service timer exceeds the first preset time, the first normally open contact KT1bIs always in a normally open state.
According to the embodiment of the disclosure, when no person is in the key area, the human body induction switch KHOpen, the second control branch 210 is short-circuited,second coil K2aOut of operation, second normally open contact K2bOpen, causing the second timing branch 220 and the second alarm branch 230 to open.
According to the embodiment of the disclosure, when a person is in a key area, the human body induction switch KHClosed, second coil K2aOperating, second normally open contact K2bClosed, the second timing branch 220 is conducted, and the second timer KT2aAnd starting timing.
According to the embodiment of the disclosure, when the timing exceeds the second preset time, the second timer KT2aControl the third normally open contact KT2bAnd when the alarm is closed, the second alarm branch 230 is conducted, and the second alarm module 240 works.
In the embodiment of the present disclosure, the open-door alarm circuit 100 further includes a human light L5 and an unmanned light L6. Wherein the manned lamp L5 and the second coil K1aThe unmanned lamp L6 is connected in parallel with the second control branch 210, and the unmanned lamp L4 is also connected in series with a third normally closed contact K2c. When no person is in the key area, the human body induction switch KHWhen turned on, the people light L5 goes off, the second coil K2aThe operation is stopped, so that the third normally closed contact K2cThe reset is closed and the drone lamp L6 lights up. When people are in the key area, the human body induction switch K is usedHWhen closed, the LED lamp L5 is on, and the second coil K2 is onaOperate so that the third normally closed contact K2cOff, the no light L6 goes out.
The second alarm module 240 includes a retention alarm lamp L7, a retention buzzer LS2, and a remote retention alarm lamp L8. The door alarm lamp L7, the retention buzzer LS2, and the remote retention alarm lamp L8 are connected in parallel. The second alarm module 240 is located in the second alarm branch, and when people are in the key area and the residence time of the people exceeds a second preset time, the second normally closed contact K1cAnd a first normally open contact KT1bAll closed, the first alarm module is working, the retention alarm lamp L7 is on, the retention buzzer LS2 is on, and the remote retention alarm lamp L8 is on.
In the embodiment of the present disclosure, the lamp and the buzzer are reminding devices for reminding the staff of the staying time state. The manned lamp L5, the unmanned lamp L6, the detention alarm lamp L7, the detention buzzer LS2 and the remote detention alarm lamp L8 are all arranged in the key area and are used for reminding field personnel working and patrolling in the key area, and the detention time of the personnel is too long; the remote detention alarm lamp L8 can be arranged in a security studio for reminding security personnel, and the detention time of people in an important area is too long, so that important potential safety hazards exist.
It should be noted that the structure of the second alarm module 240 in fig. 5 is only schematic, and the second alarm module 240 may include not only the retention alarm lamp L7, the retention buzzer LS2 and the remote retention alarm lamp L8, but also an information transmitter to transmit information that the person is not leaving the site in time to the enterprise security system for keeping a file; the voice prompt device also can comprise a loudspeaker for playing reminding voices of 'personnel stay too long and please leave in time' and the like, and is helpful for field personnel to realize the problem of too long stay time and leave the site of a key area in time. In the second alarm module 240, the remote detention alarm lamp L8 can also be connected in series with a time delay device, and is used for the remote detention alarm lamp L8 to be turned on after the detention time of the detention personnel exceeds the second preset time and the detention personnel still last for a period of time. The purpose of using the time delay unit is to prevent that the security personnel from leaving the key area range on the way to the scene after obtaining the warning of long-range delay alarm lamp L8 for the field personnel, make the manpower extravagant.
It should be understood that the number and position of the lamps and buzzers are merely illustrative and can be set according to actual needs. For example, the retention alarm lamp L7 and the retention buzzer LS2 may be disposed on a unified panel as shown in fig. 2, or two retention alarm lamps may be disposed inside the key area, so that the worker may be reminded that the door is not closed after entering the key area.
Fig. 6 schematically shows a circuit diagram of the gate inhibition circuit 300. The door access circuit 300 is used to prevent unauthorized persons from entering a key area, and is connected in parallel to the non-closed door alarm circuit 100 and the person staying alarm circuit 200.
The access control circuit 300 includes an identification device 310 and an electrically controlled lock 320. Because only authorized personnel can enter the key area, the setting of the authorized personnel can be set according to the actual requirement. For example, in the case of a bank vault, authorized personnel are limited to relevant administrative or security personnel; the authorized person may be anyone with the bank's ATM cell.
And the identity recognizer 310 is used for recognizing the identity of the person who enters the key area and confirming whether the person is authorized. The identification method of the identity recognizer 310 may be fingerprint recognition or face recognition. The electronic control lock 320 is arranged on the key area gate, is connected with the identity recognizer 310 in series, and is used for controlling the key area gate to be opened after the identity recognizer 310 confirms that the personnel to enter the key area are authorized.
Fig. 7 schematically shows a circuit diagram of the power input circuit 400. The power input circuit 400 is used for transforming 220V alternating current into low-voltage alternating current and supplying power to the unclosed alarm circuit 100, the personnel retention alarm circuit 200 and the entrance guard circuit 300. The power input circuit 400 is connected in series with a power switch KDFuse FU and transformer B1.
Power switch KDAnd the power switch is used for controlling the monitoring device. The fuse FU is used to prevent the entire monitoring device circuit from being overloaded. The transformer B1 is used to convert the 220V mains supply into the voltage required by the monitoring device.
It should be noted that the power input circuit 400 may include more than the power switch KDFuse FU and transformer B1. The monitoring device can also comprise a power supply reminding lamp for reminding workers that the monitoring device is running. A rectifier may also be included for converting alternating current to direct current.
