The Well Ventilated System Of The Mineral Well Reports To The Police The System Automatically

According to the problems of real time examing and managing the wind pressure and the air pressure ,we design a set of automatical system well ventilated system which includes information processing and computer communication technology. We choose the 8-bit minal processor which has the automatic function of identity address,low powerwastes,low price and high gather degree—P89LPC932. Many kinds of intelligence sensor on-site collect and store the data and the time at the well bottom, and communicate with the cent of monitor stand through the M-BUS public total lines. The computer on the ground sends out instructions to make use of the modem through the telephone line to communicate with each cent of monitor stand,which makes the computer on the ground gets the information of every tested point real-time and exactly. At last,the computer transmits the information in the well bottom to the data bank of system of well ventilated system of automatically alarm in the well bottom. Chinese management software system automatically manages the data bank,accomplishes the functions of enquiry,alarm,report display and printing.The article emphasizes on the usage of P89LPC932 developed by the Philips Company, many kinds of intelligence sensor, M-BUS public total line and A/D7714, and the design thought, working principle and implementation method of hardware circuit, and detailedly introduces communication flowchart between the intelligence sensor and the cent of monitor stand and the establishment and the software operation of each kinds of intelligence sensor.
