Tracking smart car circuit board solution development

With the further development of my country's artificial intelligence technology, self-driving cars have attracted more and more attention. With the development of computer technology and automation science and technology, the application of smart cars in fire protection, transportation and other fields has become more and more extensive. new direction.

1. Structural design of the tracking car system

1.1 The overall structure of the tracking car

The tracking smart car system mainly includes five parts: power supply, regulated power supply module, motor drive module, single chip microcomputer minimum system, tracking sensor module, etc., with modularization as its design leading idea. When the intelligent tracking car is working, the tracking sensor module uses the corresponding equipment to detect the relevant information of the car's running road surface, and inputs such information into the minimum system of the single-chip microcomputer. The minimum system of the single-chip microcomputer analyzes and processes the received data information, and then uses The advanced control algorithm issues corresponding instructions to the drive system, and drives the trolley to move toward the established trajectory or change the corresponding trajectory according to the feedback road surface information.

1.2 Tracking car hardware design

The hardware design of the tracking intelligent car system mainly includes the following three parts: the main circuit and the speed regulation and display circuit design, the motor drive circuit design and the optical disk encoder circuit design. When designing the main circuit, speed regulation and display circuit, STC12C5A60S2 can be selected as the main control chip of the minimum system of the single-chip microcomputer. Excellent features, it has greatly improved the traditional 8051 single-chip microcomputer, so that it has many new functions on the basis of being compatible with the traditional single-chip microcomputer, which greatly improves the operating efficiency of the single-chip microcomputer system. The main circuit system mainly includes the crystal oscillator circuit and the reset circuit, among which the button circuit can be used to adjust the system speed, and the display circuit can be used to display the driving speed and distance of the smart car in real time. When designing the motor drive circuit, it often happens that the current of the single-chip computer cannot directly drive the DC motor. Therefore, in order to solve the problems of insufficient driving force and changing direction of the intelligent tracking car, the following two solutions can be adopted mostly. One is to choose a dedicated The driver chip, the second is to choose a driver circuit composed of discrete components. In addition, when designing the photoelectric encoder circuit, in order to further optimize the speed and distance display of the current smart car, the design of the speed acquisition circuit should be further strengthened. On the basis of the principle of photoelectric speed measurement, the staff can obtain the level generated in the single-chip microcomputer system through mechanical equipment such as discs, motor shafts, and light-emitting diodes, so as to calculate the input pulse of the single-chip microcomputer port, and then convert the real-time speed of the motor and distance.

1.3 Tracking car software design

The software design of the tracking smart car system mainly includes the following three parts: the overall program flow diagram, the motor speed and distance acquisition algorithm, and the smart car tracking algorithm. When designing the program flow diagram, the designer needs to put the four actions of the car, front, back, left, and right into four functions for easy calling, and at the same time fix different modes in the corresponding timers. For example, turning on the switch of timer 1 indicates that the current intelligent tracking car system is in counting mode, and turning on the switch of timer 2 indicates that the current intelligent tracking car system is in timing mode, so as to effectively collect various information during the driving process of the car . Among the sensors used in the system, designers often need to design the black and white line information processing center to make the car run in a predetermined direction. When designing the motor speed and distance acquisition algorithm, the optical disc code disc is often selected to measure the speed of the car, and the specific speed of the motor is calculated through the corresponding programming formula, so as to convert the actual speed and travel distance of the intelligent tracking car. When designing the tracking algorithm of the smart car, designers often use infrared detection method to analyze the specific information of the car's driving road, so as to determine the specific position of the black line and the driving route of the car.

2. Tracking car system test and function realization

In order to further test the relevant performance of the intelligent tracking car, the staff conducted a tracking track test and a tracking test of the host computer monitoring system. The test results show that the intelligent tracking car can track to the designated location according to the pre-set relevant route, and ensure stability, reliability and safety in the process. The host computer monitoring system can effectively transmit the route commands set in advance by the staff to the smart tracking car through corresponding equipment, so that the car can effectively receive the corresponding route information in real time and complete the goal of automatic tracking of the smart car.

Summarize

In short, with the development and further maturity of autonomous driving technology, the IT industry and the automobile industry have gradually increased their attention to smart tracking cars. Smart tracking cars with strong safety, stability and high degree of automation have received more and more attention. Much attention. Therefore, relevant designers should, on the basis of mastering the theoretical knowledge of tracking smart car design, design smart tracking cars that meet the actual situation according to the operating characteristics of different industries, so as to further improve the work efficiency and operational efficiency of enterprises, and also contribute to my country's Make certain contributions to the further development of tracking smart cars.
