Abstract
This article to the coal mine shaft transformer substation high-voltage power supply present situation and in the domestic and foreign related product survey analysis's foundation, developed set of mine shafts to supply the power distribution safe supervisory system. In order to realize computer's long-distance range monitoring, designed the correspondence connection to complete the signal transformation, monolithic integrated circuit AT89C52 uses to control the baudrate the choice, strengthened the correspondence connection versatility. The intelligent gathering independence in the original synthesis protective device, the electric current sensor, the data processing software and so on, the real-time gathering high pressure power distribution switch brings the load voltage, the electric current, the ambient temperature, the vacuum switch to open and close parameters and so on condition, simultaneously carries out the ground-based computer to send in “switches on ', “minute floodgate”, “replacement” and so on control operations. In order to reduce the ground-based computer to patrol in turn measured that all intelligent gathering time, has designed the double monolithic integrated circuit structure transformer substation substation, the transformer substation substation in the computer and between intelligent gathering, carries on the data interim and the cushion with piece of pair of mouth RAM, may realize the two-way communication, is playing the role which in the overall system structure links the preceding with the following, The paper while carries on the above hardware design, but has designed set of computer multi-purpose softwares, mainly includes the serial communication procedure and the database.
