Embedded type software system of intelligent temperature and humidity controller for distribution system and the software design method

Abstract

The present invention relates to an embedded software system and the method of an intelligent temperature and humidity controller used for electrical supply and distribution system ; combined with the hardware circuits of WHD series, the system can realize the controlling and measuring of the temperature and humidity to loops from the first to the third, and has key-programmable as well as RS485 communications functions; the system comprises modules such as system initializing, key-programmable processing, temperature and humidity measuring and controlling, temperature and humidity illustrating, communications processing; the running of the software starts from the power-on or software reset, and then comes to the main program; firstly, various operating environment and the working parameters are initialized; and the following part is software loop body which is namely that the system constantly repeats the program of the part to realize the controlling and measuring of the temperature and humidity form 1 to 3 loops; measuring, illustrating, controlling and communications are realized in interrupting way according to a curtain priority; the present invention can close the temperature and humidity measuring and controlling of 1 or 2 loops, so as to realize the temperature and humidity measuring and controlling to first and second or third loops, thereby greatly reducing the types of software during the serialization process of products.

Description

technical field [0001] The present invention relates to a software system and a design method of the software. More specifically, it relates to a method for measuring the temperature and humidity of the power distribution environment used in high-voltage switch cabinets, box-type substations, terminal boxes and other equipment in power supply and distribution systems. , control, and an embedded software system of an intelligent temperature and humidity controller with programmable parameter setting and communication functions and a design method of the software. Background technique [0002] The temperature and humidity of the power supply and distribution equipment environment are important factors affecting the operation of the equipment. Excessively high temperature will accelerate the aging of equipment components, shorten their service life, and even directly cause equipment damage; low temperature, humidity, and condensation on the surface of the equipment may cause ac...
