Double MCU Closed-loop Control Method for Industrial Remote Control Receiver

Abstract

The invention discloses a double single-chip microcomputer (SCM) closed-loop control method for an industrial remote control receiver. The industrial remote control receiver includes a power supply, a main SCM, a sub SCM, an output amplifier board, a relay and an RF transceiver. The closed-loop control method includes the steps of main chip initialization, receive interruption of the main SCM, determination of the status of sub single-chip microcomputer by the main SCM, detection of the output by the sub SCM and detection of the main SCM status by the sub SCM and so forth. According to the invention, accidents due to malfunctions are avoided from the standpoint of safety and reliability and it is possible to effectively ensure the safety of personnel and equipment. The closed-loop control method is mainly used for controlling an electromagnetic proportional valve of the current type, and the cylinder movement is controlled by the electromagnetic proportional valve to control the operation of the large-scale equipment. When a transmitter is not operating, a major accident may be caused if a signal controlling the electromagnetic valve is output, and the closed-loop design of the invention can effectively prevent the occurrence of such incidents, thereby greatly improving the safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of industrial remote controllers, and in particular relates to a dual-single-chip closed-loop control method for an industrial remote controller receiver. Background technique [0002] Due to the continuous rise of industrial development and personnel investment costs, more and more automation equipment is needed in the industry to reduce the personnel costs of factories. Therefore, according to market demand, it is necessary to develop an industrial remote control and a control method for industrial remote control. , Industrial remote controls are mainly used in construction machinery, lifting equipment, agricultural machinery and other industries. The control method of the industrial remote control in the prior art generally adopts an open-loop design, and the disadvantage of the open-loop design is that the safety index cannot be effectively controlled, so that the safety of the operating equipment cannot...
