What is the working principle of remote lock? Remote control door lock system operating principle introduction. Remote door locks, as the name implies, users only need to remotely unlock the controller. This is a relatively common unlocking method in smart locks, which greatly facilitates modern home life. So, what is the working principle of remote-controlled door locks? How does the remote control door lock system work? Smart Lock China Network Xiaobian specifically through the data to the science of remote control lock works.
To understand the working principle of the remote lock, first of all know the system composition of the remote lock. The remote control door lock is composed of a transmitter, a receiver, a remote door lock control component (ie, an ECU door lock control component) and an actuator.
Detailed explanation of the working principle of remote control lockThe basic principle of the remote control is to send a weak wave from the owner of the vehicle, receive the signal from the car antenna, recognize the signal code by the electronic controller ECU, and then perform the action of opening/closing the actuator of the system. The system is mainly composed of two parts: a transmitter and a receiver.
The infrared signal or electromagnetic wave signal from the transmitter is received and sent to the door lock remote control unit.
The door lock remote control module compares and discriminates the signals received by the receiver, and if it is a correct code, the door opening or lock signal is alternately input into the automatic door lock control module through its internal output circuit, through the door lock motor or the electromagnet. To complete the door opening or locking action, if the continuous input through the door lock remote control component is judged to be incorrect code, the door lock remote control component will stop input within a certain period of time through its internal time lock circuit.
The remote control key is actually a small radio transmitter. When you press the button on the remote control key, the transmitter is turned on and it sends a code to the door lock receiver. There is a radio receiver in the door lock. The frequency of this receiver has been adjusted to the frequency used by the transmitter (usually 300 or 400 MHz is used in modern systems). The transmitter is similar to the transmitter in a radio remote control toy.
The above is the introduction of the working principle of the remote-controlled door locks organized by the smart lock China Network Xiaobian.
Kitchen knives come in all shapes and sizes to pair with each prep task. A quality chef`s knife is a multipurpose must-have for chopping, slicing, and dicing meat, veggies and fruit. Choose it`s shorter cousin, a utility knife, for smaller foods and in-hand prep work. Serrated knives and bread knives slice through foods that have a hard exterior and a soft interior.
