dc.description.abstractThis paper designs an intelligent electronic metering device for the post office. Programs realize the non-linear relationship between the price and the weight of letters. The whole system is mainly composed of hardware and software. The hardware design uses STC89C52 MCU as the core control device of the system. MPX4115 pressure sensor collects the weight data and sends the output analog data to ADC0832. The converted digital data will be sent to the single chip microcomputer for data processing and the digital tube will display the data. The system is equipped with a matrix keyboard and four independent keys, which are used to select the delivery location (local port or foreign port), express delivery or letter type (ordinary or registered letter) and screen clearing function. The matrix keyboard is used to input the unit price. The prominent feature of this design is that it can not only realize the weighing of the weight and price of general merchandise in a linear relationship, but also realize the weighing of the weight and price in a non-linear relationship such as express delivery or letter. The design of the device can improve the deficiency of the electronic weighing system in application and has certain practical significance.uk_UA
