1. The concept of automobile inspection
Automobile inspection refers to the inspection and measurement to determine whether the technical condition of the automobile meets the standard or whether the working ability is normal. Automobile inspection technology refers to the development and use of all relevant inspection hardware and software in the process of automobile inspection.
2. The classification of automobile detection technology
2. 1 Safety and environmental protection inspection
Safety and environmental protection testing is mainly aimed at the safe operation and environmental protection of automobiles, and it is divided into regular testing and irregular testing. The purpose of this test is to determine whether the vehicle has the required appearance and good safety performance, and to effectively control the environmental pollution of the vehicle. Under the condition that the car does not disintegrate, a safety monitoring system is established for the car to ensure the efficient, safe and low-pollution operation of the car.
2.2 Comprehensive performance test
Comprehensive performance testing refers to the regular or irregular testing of the comprehensive performance of automobiles. The purpose of this test is to determine whether the car has good power, reliability, safety, noise pollution and exhaust purification. This inspection mainly focuses on the quality supervision and inspection of automobile faults and their causes or hidden dangers, so as to establish an automobile quality monitoring system and achieve the purpose of this inspection technology.
3. Development of domestic automobile inspection technology
3. 1 Development course of domestic automobile inspection technology
(1) In the 1960s, China's automobile inspection technology was in its infancy. China began to study automobile inspection technology in 1960s. In order to meet the needs of automobile maintenance at that time, China's transportation department researched and developed some basic detection instruments such as engine cylinder leakage detector and ignition timing lamp.
(2) In 1970s, China's automobile inspection technology entered a development stage. With the rapid growth of China's automobile production technology and people's automobile utilization rate, China's transportation departments began to vigorously develop automobile detection technology. The number of automobile testing instruments and equipment has increased, testing items have increased, testing standards and rules have been further improved, and a comprehensive testing platform for automobile performance has been established.
(3) In 1980s, China's automobile inspection technology entered a stage of rapid development. With the rapid development of science and technology and national economy, China's automobile manufacturing industry and transportation industry have also developed rapidly. Therefore, the demand for automobile inspection technology and equipment is increasing. Therefore, China's automobile inspection technology has entered a period of vigorous development.
(4) Since 1990s, China's automobile inspection technology has been relatively mature. After entering the 1990s, China's automobile inspection technology has its own operating system from equipment research and development to production. The 1990s is the climax of the development of automobile inspection technology in China. Although there is still a certain gap between China's automobile inspection technology and foreign countries, there are also some problems and deficiencies in the development process, but China's automobile inspection technology is constantly absorbing and perfecting itself to ensure its good development trend and strive to create broad development prospects for it.
3.2 At present, the representative advanced automobile detection technology in China.
(1) virtual instrument detection technology
Virtual instrument testing technology refers to the technology of freely increasing or decreasing the configuration of the testing system, using the system to configure the unit equipment, and obtaining the monitoring results intuitively and effectively according to the requirements and standards of each project test, thus improving the testing efficiency.
(2) Combining GPS technology with vehicle detection.
This technology mainly uses the GPS system which can receive satellite positioning signals, and combines it with the automobile detection technology system, so as to realize the fast and effective detection process.
(3) Using automobile four-wheel positioning to detect.
The four-wheel alignment instrument mainly obtains the detection data according to the wheel alignment. It uses images to display and record the running situation of the four wheels of the automobile, and combines with the analysis of the results of automobile testing data to achieve the purpose of testing.
4. Problems existing in the development of domestic automobile inspection technology.
4. 1 There are problems of administrative intervention in the operation and management of domestic automobile inspection stations.
In China, security inspection is established and managed by public security departments. Therefore, the comprehensive performance testing stations in China are all directly established and managed by the transportation department or established by local enterprises but still managed by the transportation department. This form of administrative management often leads to untrue test results, nonstandard test process or imperfect test items, and even forged some monitoring data.
4.2 There is a problem of repeated testing in China's automobile testing.
At present, there are at least three organizations that have the right to inspect automobiles in China, namely, security inspection station, automobile exhaust emission inspection station and automobile comprehensive performance inspection station. These three institutions belong to public security, environmental protection and traffic control departments respectively. These departments carry out necessary inspection and monitoring of vehicles according to their respective functional requirements, which is easy to cause repeated inspection of vehicles, increase the workload of vehicle inspection and bring inconvenience to vehicle owners.
4.3 The detection technology needs to be further improved.
At present, China's imported automobile inspection standard system mainly depends on foreign inspection standards, so according to the specific development of China's automobiles, China's automobile inspection technology needs to be further improved and improved. For example, China's current technology can detect frontal, side and rear-end collisions of vehicles, but there is a lack of relevant detection standards for side collisions and rear-end collisions. This also urgently needs the improvement and perfection of automobile detection technology in China.
4.4 The overall professional ability and quality of automobile inspection personnel in China need to be improved.
On the one hand, the professional testing ability of automobile inspectors in China needs to be improved. Some inspectors themselves lack basic knowledge of automobiles, the inspection operation is not standardized, and the ability to analyze the inspection results is not enough, so they can't judge whether the automobile meets the inspection standards well. On the other hand, the quality of automobile inspectors in China is not enough. Some inspectors deliberately raise the cost of testing, disregard the collective interests for personal interests, and even cheat some substandard vehicles. These are personal factors that cause potential safety hazards, which are not conducive to the development and promotion of detection technology in China.
5. Effective measures to solve the development problems of domestic automobile inspection technology.
5. 1 Standardization of Automobile Testing Technology Basis
In the development of automobile inspection technology in China, the hardware technology of automobile inspection has been paid more attention than the software technology of automobile inspection technology. This kind of thinking often leads to the neglect of some basic technology research. Therefore, the development direction of automobile inspection technology in China should pay attention to the perfection and improvement of software inspection technology supporting hardware. There are three main points in this respect: first, formulate and improve the limit standards and testing methods of automobile testing items; Second, improve the evaluation rules of automobile technical condition testing, unify and standardize the national testing requirements and gymnastics techniques; The third is to strictly implement the certification rules for large-scale testing equipment of comprehensive performance testing stations to ensure that comprehensive performance testing stations are competent and perform testing duties.
5.2 Intelligent Vehicle Testing Equipment
Although there is a certain gap between China's automobile testing technology and the intelligence of testing equipment abroad, China's automobile testing equipment is actively learning and introducing some advanced testing equipment from abroad to improve and enhance the intelligence of China's automobile testing equipment. The intelligence of detection equipment makes the detection equipment have expert detection and diagnosis system and intelligent function, which can quickly and accurately detect the condition of the automobile in a short time, diagnose the location and cause of the automobile fault, and facilitate the maintenance personnel to quickly eliminate the fault. Save the labor cost and improve the labor efficiency.
5.3 Vehicle detection management networking
With the rapid development of computer and network technology, all walks of life in China are gradually realizing the networking of management, and the automobile inspection industry is no exception. At present, although some automobile comprehensive performance testing stations in China have realized computer management system testing, the computer monitoring system is not perfect, and the computer testing methods adopted by each testing station are also inconsistent. In order to gradually realize the consistency and effectiveness of China automobile inspection management, China automobile inspection should actively promote its management networking.
summary
With China's economic and social progress and the development of automobile industry, China's automobile inspection technology must be continuously improved and improved. In order to make the work of automobile maintenance personnel easier and improve the accuracy of automobile inspection results, the development of automobile inspection technology in China tends to automation, networking and intelligence. The perfection and improvement of automobile detection technology is conducive to the development of transportation and environmental protection in China, thus providing a good external environment for China's economic and social development.
