Abstract

A wireless control system for controlling linear actuators comprises at least: a plurality of linear actuators, a plurality of control equipments, and at least one wireless controller. The respective linear actuators are assembled on an automatic machine after being connected to a control equipment. The wireless controller and the respective control equipments are provided with a two-way sequence transmitting and receiving assembly which complies with IEEE 802. The wireless control system avoids the use of control boxes and wires while increasing the additional value. Further, the two-way sequence transmitting and receiving assembly ensures the operation status of between the wireless controller and the respective linear actuators, and prevents the direction problem of the wireless control.

Claims
