Recently, the company has gained three new patents.

01 Control method and system of wire saw

The invention relates to a control method of a wire saw, which is used to realize the safety control of the wire saw cutting stone.

A control system of wire saw machine can realize the synchronous adjustment of the frequency of wire saw motor and walking motor, improve the accuracy, and at the same time, there is no need to install another PLC system, so as to reduce the cost and improve the anti-interference performance.

02 Elevator control method and system

The invention relates to an elevator control method. The address identification codes corresponding to the elevator main control system and the door machine control system are matched and compared. If they are consistent, the matching is successful for communication.

No user intervention is needed, which makes the maintenance or installation of the elevator easier. In addition, an elevator control system is also provided. Judgment method, control method and system of elevator arriving flat area

The invention relates to a judgment method for an elevator to reach a leveling area, an elevator control method and an elevator control system applying the elevator control method.

It can effectively prevent the elevator control system from mistakenly issuing the door opening command when the leveling sensor fails or the leveling sensor fails, and the output signal can not truly reflect when reaching the leveling area, resulting in elevator safety accidents.

03 Elevator control method and system

The invention relates to an elevator control method. The address identification codes corresponding to the elevator main control system and the door machine control system are matched and compared. If they are consistent, the matching is successful for communication.

No user intervention is needed, which makes the maintenance or installation of the elevator easier. In addition, an elevator control system is also provided.
