目前,混凝土搅拌站的称量控制,基本采用三种模式:机械杠杆秤,表头式电子秤或数字式电子秤,微电脑电子秤或微电脑控制系统。微电脑在称量装置中的应用,对提高混凝土搅拌的产质量和加强企业管理提高经济效益等方面都具有重要意义,近年来,在搅拌站中逐步推广.有些搅拌站采用一台微电脑集中控制。这种方案,微电脑部分简练集中,但某一部件出故障,易使整个系统受影响,为此,就得备用多台常规电子秤,这样就使系统费用增加。随着电子器件的大幅度降价,采用微电 At present, the weighing control of a concrete mixing plant basically uses three modes: a mechanical lever scale, a head-type electronic scale or a digital scale, a microcomputer scale or a microcomputer control system. The application of microcomputers in weighing devices is of great significance in improving the production and quality of concrete mixing and strengthening enterprise management and improving economic efficiency. In recent years, it has been gradually promoted in mixing stations. Some mixing stations use a microcomputer for centralized control. In this scheme, the microcomputer is concisely concentrating, but if one component fails, the whole system is easily affected. For this reason, multiple conventional electronic scales are needed to be spared, which increases the system cost. With the drastic price reduction of electronic devices, microelectronics
