Coal gasification reactors are widely used in many industries, such as synthetic ammonia, nitrogenous fertilizer, soda ash, explosive, city gas, mechanical workshop, glass, porcelain and so on. In our country, interim coal gasification reactors are mostly used in the medium-sized and pint-sized making-gas technics, how to optimize the control of the interim coal gasification reactors directly affects the yield and quality of coal gas, it also affects the consumption of the material, so it is highly regarded by the industry. Those monitoring software of the host computer which can be managed and operated easily will extremely abstract fertilizer factories. In order to satisfy the enterprises’ demand and replace the old monitoring software, this article designs a suit of monitoring software of the host computer, this software can improve the enterprises’ automatic level and competitive ability.Aimed at the technical process of coal gasification reactors production, a suit of monitoring software of the host computer is designed. This software communicates real-timely with the slave computers of the coal gasification reactors using user-defined corresponding protocol, while its main interface simulates running environment of the scene, displays various parameters gathered from the coal gasification reactors, and real-timely shows some parameters to the users in proper forms, such as sound, graph, picture, curve and so on, so that the users can oversee the situation of the coal gasification reactors more intuitionally; at the same time the software stores data to exterior SQL database, so as to realize the long keep of the real-time data and the historical data, and convenience the workers to inquire about the data; in addition, there is OPC server interface embedded in this software, so this software can send its running data to the configuration software of the client computer quickly and effectively, it also successfully solves the difficult problem of different systems’ communication, and enhances the transmission rate of the data. What’s more, using the GSM communication technology, this software can send the alert message of the coal gasification reactors in the form of SMS to the administrators’ mobile phone, so that the administrators can take effective measures to solve the problem in time.This software has been applied in Wulashan chemical fertilizer Ltd.’s process control of coal gasification reactors production, and the running effect is very well. It is approved by the whole company.
