Electronic lock, it is also the 51 series single chip machine (AT89051) as the core, with the corresponding hardware circuit, complete the password setting, storage, identification and display, can be input up to three times; if three times are incorrect, the single chip machine through the communication line to the intelligent monitor alarm. The microcontroller sends each unlocking operation and the drive current value of the current electromagnetic actuator to the intelligent monitor as the condition information, and also sends the alarm information received from the sensor interface to the intelligent monitor together, as the basis of the intelligent analysis.
Radio lock. Non-door lock electronic lock, which can be mainly applied to logistics transportation, storage, fresh milk transportation truck, cash transportation truck, refrigerated truck, drug transportation, tobacco transportation and other transportation categories. If used for the cash truck door, special vehicle man hole cover and warehouse door, to ensure the safety of the goods transported or guarded, to avoid theft. The electronic lock uses the mechanical lock body to contact the Internet of Things related skills. The wireless transceiver module is placed in the lock body. When the lock body is on and off, the wireless transceiver module will transmit the on and off the lock signal to the monitoring host for a long distance. If the unlocking signal accepted by the monitoring host appears in the abnormal time period, the signal will be identified as stolen and pried signal, and the monitoring host immediately produces the alarm information, so that the relevant personnel can make timely disposal and avoid financial loss.
Principle of electronic lock
Electronic lock, it is also the 51 series single-chip machine as the core, equipped with the corresponding hardware circuit, complete the password setting, storage, identification and display, drive the electromagnetic actuator and detect its drive current value, receive the alarm signals from the sensor, send data and other functions. If the password is incorrect, the operator is allowed to reenter the password up to three times; if all three times are incorrect, the SCM alarms to the intelligent monitor through the communication line. The microcontroller sends the unlocking operation and the drive current value of the electromagnetic actuator to the intelligent monitor as the status information, and sends the same alarm information received from the sensor interface to the intelligent monitor as the basis for intelligent analysis.
Electronic locks are not only an important protection measure to protect your own property, but also to be careful of special treatment in extreme situations, such as electronic system failure or damage to the car, which all need to be considered by yourself.
