Abstract

The invention discloses a mining anti-interference communication module and a communication control method thereof. The mining anti-interference communication module comprises a master control single-chip microcomputer unit, an RS485 communication unit and a lightning protection anti-surge circuit. The master control single-chip microcomputer unit is in communication connection with the RS485 communication unit. The lightning protection anti-surge circuit comprises a transient diode V1, a transient diode V2, a transient diode V3, a resistor R18, a resistor R19, a capacitor CF1 and a capacitorCF2.A synchronous clock is adopted for information transmission, and the functions of high anti-interference and error code prevention are achieved. The transmitted data packet is verified by adoptingCRC-16, so that the data verification capability is improved, wrong data is prevented from being adopted, and misjudgment in the communication process is avoided. The invention accords with the actual mine environment, is high in anti-interference capability, is low in data error rate, and guarantees the bus data transmission safety of a monitoring system.

Description

technical field

[0001] The invention relates to a mining anti-jamming communication module and a communication control method, belonging to the technical field of communication control. Background technique

[0002] Mine safety monitoring system is an emerging technology following the current needs of mine safety production and the maturity of automation technology. The rational use of safety monitoring system can bring great help to mine safety production. With the help of the mine safety monitoring system, the staff can detect the data of each position sensor of the monitoring system without having to conduct underground inspections, and grasp the environmental parameters of each position of the entire mine. When there is an environmental parameter exceeding the limit, the system can automatically issue an alarm and control command to remind the staff to pay attention and control the power failure of the equipment in the dangerous area. At present, national regulations ha...
