Problems solved by technology
[0002] my country's coal mines are mainly underground mines and open-pit coal mines. In terms of safety, underground mines have relatively high implementation standards. At present, my country uses dust-proof technology: basically adopting wet rock drilling on the working face, flushing the rock sides, installing rocks and sprinkling water , Spraying before and after blasting and personal protective measures; coal seam water injection in coal mining face, spraying water inside and outside coal mining units, water curtain purification in main transport roadways, water spraying at loading points and other measures, but these comprehensive dust prevention and control measures are often only palliative, and A lot of manpower is wasted, the interval between dust prevention cycles is short, the root cause cannot be cured, and the accumulation of dust cannot be effectively prevented; therefore, the research on the intelligent spray control system based on wireless sensors in the fully mechanized mining face has effectively improved the coal mine operating environment and ensured the health of employees

Embodiment Construction
[0014] The present invention will be further described below in conjunction with drawings and embodiments.
[0015] Such as figure 1 , The composition of the control system is divided into four parts from the physical structure: wireless sensor end, wireless collector end (substation), host computer and computer end. The four parts are closely connected; the combination of the four provides a powerful spray scheduling function, which can be set up for on-site needs to achieve the optimal spray dust reduction mode.
[0016] The spray master station uses dual single-chip microcomputers to work. The first single-chip microcomputer with dual serial ports STCI2CSA60S2 is responsible for collecting the data of the downlink spray sub-station, displaying the running status and settings, and storing the downlink data in the dual-port RAM. The second single-chip microcomputer STC11L16 The downlink data collection in RAM is transmitted to the computer. The system adopts 64K dual-port R...

An intelligent spray control system for fully mechanized mining working faces based on wireless sensors. On the basis of the safety monitoring system, it is interconnected with the ground dispatching center system. Through the conversion of the 485 to Ethernet module, the ground monitoring center realizes remote browsing of fully mechanized mining working faces. The real-time distribution map of the spray status is provided for the production scheduling center and relevant leaders to command and make decisions, and further improve the fine management level of the coal mine underground spray system. The control system solves the constraints caused by connecting cables in some applications and makes long-distance transmission possible. The hardware defines a unified sensor interface, and the software introduces a logical mechanism consistent with on-site applications, which is convenient for the actual application of mines.
