Along with the development of science and technology, demands of the modern industrial production for the automation degree of control and the modern management are ever increasing. Radio technology, computer technology and technique of sensor measuring has been widely used in weighing technology field.
Electronic crane scale, as a kind of electronic scale classification, its development and progress is also associated with the development and progress of the electron weighing apparatus. The introduction of wireless electronic balance is to bring great convenience and improve production efficiency. Wireless electronic balance makes the use of intelligent characteristics of the microcontroller and the wireless communication, accomplishing the wireless transmission of the weigh results and the scale parameter setting.
This article introduces the hardware and software design of weighing display equipment based on wireless communication. The weighing display equipment is used for supporting the use of wireless electronic hook scales. It adopts LCD screen and can directly show the weighing results of the weighing scale crane. The low power design makes the battery life longer. Weighing records can be saved in the serial EEPROM. Weighing records can be transmitted through UART to a PC or special micro-printer. Also, the weighing results can be queried.
