51 Single Electronic Truck Scale Design

Electronic truck scale can be divided into analog and digital two, electronic truck scale early analog, common now is the digital. Digital electronic truck scale weighing sensor measurement to electrical signals, after amplifier, converted into digital signals by ADC, then processed by other digital devices. This is conducive to the load transmission and processing of the data, also easy to let into the information management system of enterprises, therefore, the mainstream digital electronic truck scale technology is today’s auto balance technology development.Truck scale weighing sensor is used in the design of AD converter and the high precision, with STC89C52RC as control core, using non-contact IC card technology, can automatically identify the customer, and the friendly man-machine interface, so as to improve the accuracy of weighing weighing, simplify procedures and reduce the load time. The car balance control system is connected to the computer using the RS232interface, powerful data processing ability of the computer, realizing the weighing data recording, statistics, settlement, weighing and convenient management of enterprises. Therefore, can significantly improve enterprise weighing efficiency and the level of information management, saving production resources, reduce production cost.The design of the content can be divided into two parts of hardware and software. The hardware part can be divided into the weighing module, IC card reader module, display module and control module four parts. The software part is the main control program system initialization program, weighing the event handler and each module.
