Electronic lock, it is also based on 51 series single-chip microcomputer (AT89051), with corresponding hardware circuit, complete password setting, storage, identification and display, drive electromagnetic actuator and detect its drive current value, receive sensor sent alarm Signal, send data and other functions.
The MCU receives the entered code and compares it with the password stored in the EEPROM. If the password is correct, the electromagnetic actuator is unlocked; if the password is incorrect, the operator is allowed to re-enter the password, up to three times; if three times If it is not correct, the MCU will alarm the intelligent monitor through the communication line. The single-chip microcomputer sends the unlocking operation and the driving current value of the electromagnetic actuator as the status information to the intelligent monitor at this time, and also sends the alarm information received from the sensor interface to the intelligent monitor as the basis of the intelligent analysis.
Wireless electronic locks. Non-door lock electronic locks can be mainly used in transportation and transportation, warehousing, fresh milk transport vehicles, cash transport vehicles, refrigerated trucks, pharmaceutical transportation, tobacco transportation and other transportation fields. It is mainly used for transportation vehicle doors, special vehicle manhole covers and warehouse doors to ensure the safety of goods transported or guarded and to prevent theft. The electronic lock adopts a mechanical lock body combined with the Internet of Things related technology, and the lock body has a built-in wireless transceiver module. When the lock body is opened and closed, the wireless transceiver module transmits the open and close lock signals to the monitoring host remotely. If the unlock signal received by the monitoring host appears in the abnormal time period, the signal is judged as the stolen and beaconed signal, and the monitoring host immediately generates an alarm message, so that the relevant personnel can timely deal with it to prevent financial loss.
