For the present, China colliery coal spontaneous combustion under pressure and pressure conditions of real-time detection , management and other aspects of the many problems , we have designed a set of information processing and computer communication technology in one of the mine ventilation system automatic alarm system. In this system, we chose the Dutch Philips company developed a kind of automatic address recognition feature , low power, low cost, highly integrated 8-bit microprocessor -P89LPC932, through it by a variety of smart sensor underground scene collected and stored data and time , and then through the M-BUS bus makes various intelligent sensors and downhole monitoring station communication by computer to send commands on the ground , the use of a modem via telephone line a monitoring station on the underground communication , making the ground on your computer in real time and accurate understanding of the various measuring points downhole information , and finally the computer will transmit information to the underground mine ventilation system automatic alarm system database management software system by the Chinese automatic processing of the database , information inquiry, automatic alarm, report display and printing capabilities. This article focuses on developed by Philips P89LPC932, a variety of smart sensors , M-BUS bus A/D7714 and other devices are used, and the hardware circuit design ideas, working principle and method , and details of intelligent sensors and monitoring setter communication flow stations and various intelligent sensor software operation .
