Design Ideas

The single chip microcomputer with digital clock has been designed based on AT89C52, through the design ideas of multi-function digital clock, we have described the system hardware, software and the realization process.The display design and implementation of a year, month, day, time and second is achieved using C language. And the simulation is used by Proteus software. By comparing the actual clock, we have found out the source of the error and have determined the method of adjusting error, and we reduce the error as much as possible, so we can achieve the allowable error range for a practical digital clock in this system.

Information Interaction

A robot based on STC12C5A60S2 single-chip-microcomputer is designed for improving the production efficiency and reducing repetitive work. The system could identify path by detecting metal using eddy current sensor. By ways of the single-chip-microcomputer controlling stepper motor, the robot can run according to the predetermined route, judge independently cargo range and deliver the goods to the designated location. The implementation methods of the important links, such as mechanical structure design, path recognition and steering engine driving and so on are introduced, the system of which make the information interaction with computer through ISP-module (In-system-programming).by testing the model, it shows that the system can meet the design goals of handling goods automatically, and it has higher application value of reducing the accident rate of worker in repeated works and improving labor productivity.

This paper elaborates the control of environmental factors in the modern industry and agriculture, and according to the problem that the temperature and the humidity is hard to control automatically, this paper puts forward the design of the greenhouse automatic control system based on MSP430 single chip microcomputer. This design mainly introduces the overall design scheme of the automatic control system, and the use of the properties of various hardware based on MPS430, which mainly include temperature transmission sensor DS18B20 and the humidity transmission sensor CHR01. And then use the environmental control factor algorithm and numerical conversion fuzzy algorithm, so as to realize the temperature and humidity control system.

Mine Hoist

Known as the mine's throat, the mine hoist is the key equipment to the underground work lifting materials and personnel. But due to the negative downhole conditions, mine dot signals tend to appear wrong and be perceived inaccurately. In order to avoid the mine accident and ensure the safety of mine transportation operations, this design chooses the single chip microcomputer U101 with an high anti-jamming ability and develops a mine dot signal equipment applied in mine hoist system to test and transmit signals.

Using the equipment, YL-236 single chip microcomputer (SCM) control device installation and debugging training platform, used in the SCM event of the National Vocational Students Skills Competition (NVSSC) as hardware carrier, this paper researched the application method of real-time operating system (RTOS) in the implementation of the SCM Skills Competition task, and apply the real-time multitasking operating system (RTMOS), RTX51, in the 8-bit 51 SCM. That allows switch of circulation tasks, supports the signal transmission, utilizes the interrupt function in parallel, and has very small demand for RAM. That makes whole SCM task to develop much easier and more convenient, and enhances the real-time performance and reliability of the SCM Skills Competition task at the same time.

This paper focuses on the design and implementation of a Smart Trolley Shopping in supermarkets to solve difficulties of customers whilst waiting in queues for billing.  The trolley is designed to develop market services and make them modern, healthy and easy to use. The remote controls the movement of the trolley automatically and reduces the load on the client during pulling the trolley. In addition, it helps in saving money by not buying unwanted products, with the help of the Liquid Crystal Display  in the trolley, which shows on the update of purchase limit. In this work the client writes the amount they have via the keypad, where the amount appears on the liquid crystal screen. The product used is then checked for price and RFID details. This information is sent to RFID in the product via radio to RFID reader which determines the radio waves. It has an antenna bar for receiving and transmitting data. It also contains a small memory for detailed information of up to 256 bytes. The total cost is summarized by the scanner for materials stored in memory, sent to Arduino. The cart moves according to the client's movements when shopping and then moves to the left, right, forward, backward, or even stops through the buttons. If the customer purchases the products more than the amount recorded on the keyboard, an alarm will serve as a reminder to the customer that he/she has exceeded the purchase limit. The smart trolley is characterized by the speed of accounting compared to conventional accounting and provides a quality  service. It reduces congestion  at the cashier counter and shortens the time and waste of effort during the accounting process.
