1. The principle of magnetic lock and electric bolt lock
The working principle of the magnetic lock (or electromagnetic lock) is the same as that of the electromagnet. It uses electricity to generate magnetism, and then the opposite poles attract each other. When the current passes through the silicon steel sheet, the electromagnetic lock will produce a strong suction force to attract tightly. The iron plate achieves the effect of locking the door. As long as a small current electromagnetic lock will produce a huge magnetic force, the access door control system that controls the power supply of the electromagnetic lock will cut off the power after identifying the correct personnel, and the electromagnetic lock can open the door after it loses its suction.
Because the electromagnetic lock has no complicated mechanical structure and the structure of the bolt, it is suitable for the passage control of the escape door or the fire door. The lock body is protected by pouring epoxy resin inside. At present, the suction strength of electromagnetic locks is expressed in LB (pounds), and the test method is static pressure. The so-called static pressure means that the electromagnetic lock gradually increases the pulling force on the adsorption iron plate after the electromagnetic lock is energized. When the suction force of the electromagnetic lock is exceeded, the adsorption iron plate is pulled open instantly. The data of this tensile force is the tensile force value of the electromagnetic lock. Moreover, the force of the electromagnetic lock and the adsorption iron plate must be face to face and a collinear load test, so that the holding force of the electromagnetic lock is the largest. The adsorption iron plate may be temporarily magnetized due to the magnetic induction of the electromagnet for a long time.
The electric mortise lock is a kind of electronically controlled lock, which drives the extension or retraction of the "bolt" through the on and off of the current to achieve the function of locking or opening the door. Of course, the realization of the function of closing the door and opening the door needs to cooperate with the "magnet" to realize it. Generally, an electric bolt lock is composed of two main parts: a lock body and a keyhole. The key component in the lock body is the "lock tongue", which can be combined with the "lock hole" to realize the two states of "closed" and "opened". That is, the lock tongue is inserted into the lock hole to close the door, and the lock tongue leaves the lock hole to open the door. Because of the retractable function of the bolt, it was given the name "electric bolt lock". It is precisely because of this feature that electric mortise locks are often used on various swing doors (two-way opening). At the same time, its "hidden" installation feature is more suitable for places with higher requirements on the confidentiality of the lock body.
2. The difference between a magnetic lock and an electric mortise lock
In modern building wiring. Access control card, magnetic lock, electric bolt lock. The transfer of signal output between. Usually the signal transmission method between them is through RS422, RS485, RS232 several commonly used data transmission methods, among which RS422 is a duplex data transmission method. Transmitted to the outside. The transmitted data is generally in odd numbers. Three-wire and five-wire signal wires are used for wiring more. In the placket system, it is used for signal induction of magnetic locks or electric bolt lock.
RS485 communication converter. It is the double and half odd data transmission signal. His characteristic is that there is less wiring. The transmission distance is long and the magnetic lock or electric mortise lock connected to it should not be too many. If there are too many, it must be divided into multiple interfaces without management. But relatively speaking, the agreement will be more complicated. They are generally used in the doorway of the intercom between the building and the building. Magnetic locks or electric mortise locks transmit signals. RS323 communication converter is used in smart devices. It is characterized by short transmission distance. Nowadays, the application of smart devices in the community is relatively common. So its application is also the most extensive.
With the continuous progress and development of the security industry. Signal technology is also being widely promoted, and community intelligent systems are also being used on a large scale, signal control technology. Signal control technology has been continuously applied to magnetic locks and electric bolt locks for entrances and exits of residential quarters. The same is used in other security products.
