Abstract
The utility model relates to important depot gate inhibition management in special industry and safeguard self protection device of vital department, which comprises a main controller and an electronic lock internal controller. The CPU controller is connected with a relay J2 and a wireless transmitting modular. The wireless receiving modular is connected with a relay J1 and electronic lock coil. One end of the electronic lock coil is connected with the wireless receiving modular, and the other end is connected with the junction J1-1 and junction J1-2 of the relay J1. The junction J1-1 of the relay J1 is connected with the ground terminal. The junction J1-2 is connected with a power of 12V. The utility model has the advantages of achieving dual control of the electronic door lock which is safe and reliable.
Description
Technical field
The utility model relates to the important storehouse chamber entrance guard management of special industry, key departments' safety precaution self-protecting device.
Background technology
Because chamber, the important storehouse access control system (two-door twin-lock) of special industry; be mainly used in national important unit and key departments; so safety, reliable, maintain secrecy and self-protection requires very highly, a kind of safe precaution measure that proposes at the self-protection of electronic lock is quite necessary.At present the method during the artificial destruction gate control system is a lot, and for example: the control door lock lead that will expose is cut off, and inserts 12V dc source (generally electronic lock voltage is 12 DC voltages) electronic lock is opened.Perhaps, when gate control system implement is destroyed, situation such as also easily electronic lock is opened.
Summary of the invention
At the situation of prior art, the utility model provides a kind of key departments' safety precaution self-protecting device with double protection functions.
Key departments' safety precaution self-protecting device is characterized in that: this device is made up of master controller and electronic lock internal controller, and master controller is made up of cpu controller, wireless transmitter module, relay J 2; The electronic lock internal controller is made up of wireless receiving module, relay J 1, electronic lock coil;
Described cpu controller connects relay J 2 and wireless transmitter module, is used for the adhesive of control relay J2, to supply with device 12V power supply; Also be used for controlling 1 work of wireless transmitter module emission control relay J, receive operational data by wireless receiving module; Whether also be used for each sensor states of inspection panel access control system normal;
Described wireless receiving module connects relay J 1 and electronic lock coil, and wireless receiving module is used for receiving the operational data of being sent by wireless transmitter module, and control relay J1 work;
Described electronic lock coil one end is connected with wireless receiving module, and the other end is connected with contact J1-1, the contact J1-2 of relay J 1; The J1-1 contact of relay J 1 is connected with earth terminal, and the J1-2 contact connects the 12V power supply.
The utility model has the advantages that electronic lock has been realized dual control, safety, reliable.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
The specific embodiment
See Fig. 1, this device is made up of master controller and electronic lock internal controller, and master controller is made up of cpu controller, wireless transmitter module, relay J 2; The electronic lock internal controller is made up of wireless receiving module, relay J 1, electronic lock coil.Its operating principle is described below:
Do not receive control " cpu controller " not output when opening the door lock signal in control system, " relay J 2 " not adhesive J2 contact does not have 12V output, this moment, the electronic lock internal control circuit did not have power supply not work, the normally closed ground connection of J1-1, " electronic lock coil " short circuit.During if any destruction, go into 12V voltage in the electronic lock termination, " wireless receiving module " do not receive control " J1 relay " operational data, and " J1 relay " do not work, and door lock can not be opened.For another example: when gate control system is implemented to destroy, undesired back " relay J 2 " the not adhesive of each sensor states of " cpu controller " check system, " wireless transmitter module " do not export control " J1 relay " operational data simultaneously, and it is system's automatic blocking that electronic lock can not be opened.
When control system receives control " cpu controller " output when opening the door lock signal, " relay J 2 " adhesive, the J2 contact has 12V output, electronic lock internal control circuit " wireless receiving module " energising work this moment, but do not receive control " J1 relay " operational data this moment " wireless receiving module ", and " J1 relay " do not work.When " cpu controller " once more each sensor states of check system normal after, by " wireless transmitter module " output control " J1 relay " operational data.After " wireless receiving module " receives control " J1 relay " operational data, " J1 relay " work.The J1-2 contact is connected " electronic lock coil " power supply, door-lock opening.The adding of this circuit has promptly reached the purpose of dual control and has protected oneself again.
