Smart car detection line solution based on Internet of Things technology

The smart car detection line solution comprehensively uses radio frequency, microwave communication and other technologies to accurately and effectively monitor the information of the vehicle under test and the information generated by the vehicle detection line in real time, improve the detection efficiency of the detection line, and increase the transparency of the owner's knowledge of the detection information. The vehicle inspection management department can grasp the detection status of vehicles in Wuhan in a macroscopic way.

With the acceleration of urbanization and the increasing popularity of automobiles in China, the technical means of daily vehicle inspection and management are relatively lagging behind, and the contradiction between vehicle safety hazards caused by the rapid increase in the number of motor vehicles has gradually emerged. At the same time, the vehicle inspection function is The opening of the society has brought many problems such as non-uniform vehicle inspection process standards, lax supervision, and low efficiency. The program aims to apply intelligence testing methods such as the Internet of Things to standardize the testing process, report and publish mobile phone detection information and other value-added services.

China's automobile inspection status

At present, most vehicle management offices in China use annual semi-automatic operation modes for the annual inspection and routine inspection of motor vehicles in their respective regions: semi-automatic inspection lines + manual entry of vehicle-related data. In addition, due to the continuous increase in the number of vehicles inspected each year, the annual inspection of motor vehicles is gradually open to social enterprises. It is precisely because the annual inspection business after opening up may be affected by various objective situations such as employees or geographical location, it is impossible for the competent business department to verify the actual test results of each vehicle in real time, so there will be some private vehicle inspection line processes. The objective situation is that the standards are not uniform. On the one hand, the supervision of the vehicle inspection business is confusing due to the lack of supervision, resulting in damage to the image of the competent authorities. What is more serious is that once these unqualified vehicles flow into the society, they will bring great hidden dangers to consumers' lives and property.

The owner of the vehicle waits for a long time in the inspection process and cannot transparently understand the detection result in the process of the vehicle detection line. This is also a problem commonly encountered by the owner in the vehicle detection.

The particularity of Wuhan vehicle inspection

As far as Wuhan City is concerned, the current vehicle detection outlets are relatively independent, and there is a lack of timely data transmission between them. The supervision department cannot understand the detection status of each outlet. The vehicle detection outlets are scattered, the utilization rate of the outlets is not high, some outlets are overcrowded, and some outlets are left out, which directly affects the owner's ability to question the management ability of the regulatory authorities and increase the number of complaints. If the owner can know the vehicle detection status of the outlet at the first time, it can well avoid this problem.

The after-sales service system of most test line manufacturers is not yet complete, and the technicians at the test line site can only solve some simple fault diagnosis problems. When a system failure occurs, experts can only be asked to go to the site for diagnosis. Such maintenance of the vehicle safety performance test line is a typical on-site maintenance mode, and the other party calls - travel maintenance - maintenance returns. This traditional on-site maintenance mode is dull in practical applications, making the detection line inefficient, and also a waste of human resources and capital. It is imperative to improve the efficiency and standardization of motor vehicle inspection work.

Smart car inspection solution

Through the on-site investigation and analysis of the vehicle testing line in Wuhan, a comprehensive performance testing line system supervision solution is proposed for the above problems. The system is divided into four major units:

Automatic identification detection unit

At the beginning of the detection pipeline, an RF reader (which can be considered in conjunction with the existing ETC) and an electronic display are provided. Once the vehicle to be inspected is approached, the reader will read the vehicle ETC data and transmit the relevant information to the core supervision platform. The supervision platform writes the information into the car E detection APP, and the owner scans the two-dimensional code through the mobile phone terminal to enter the car E to detect the vehicle detection information. In each detection step, it is equipped with an electronic display and a wireless network system, and the owner can know the vehicle detection situation in real time through the electronic display.

Big data supervision unit

The information of each detection network is collected in the supervision platform in time, and the data is processed by the background data processing center, and returned to the supervision platform. The monitoring platform then carries the data on the inspection line with the external mobile phone owner terminal, the supervision unit and other value-added services. Interconnection, so that mobile phone owners can understand their vehicle detection process in a timely manner, enabling the supervisory unit to better manage the vehicle inspection work, and more convenient for other service units to improve the vehicle in all aspects. In addition, the mobile phone owner can also know the information of each inspection network through the supervision platform, and play a good guiding role in selecting which outlet to check the vehicle, so as to avoid delaying the owner's time and allowing the owner to enjoy the quality of the vehicle inspection more conveniently. service. In addition to allowing the owner to choose the outlets, the big data supervision can also enable the supervisory unit to bring strong tools to the better management of the customers. The supervisory unit can timely understand the operation status of each outlet through the platform, and timely dispatch personnel and vehicles to each outlet. Coordination makes an accurate judgment.

Public service unit

The mobile terminal owner can understand the information required by the vehicle through the core supervision platform. Before the pipeline detection starts, the owner obtains the vehicle inspection information. The mobile phone information includes the owner's license plate number, the owner's name, the owner's purchase stamp, and other information. Waiting for information. The readers set up at the outflow line will also read the completion of the vehicle detection, and the relevant information will be sent to the core supervision platform. The owner's mobile phone can read the vehicle inspection information through the vehicle E detection APP, and can prompt the detection result, including the pass or fail. If there is any problem and the amount of payment, the owner will receive the test result and pay the fee after seeing the information. In this way, the owner can know the detection situation in real time during the detection process. If there is any unqualified situation, he can contact the relevant department in time to obtain relevant information and then select the treatment method.

The system integrates radio frequency technology (RFID), microwave communication technology, computer network technology, Internet of Things information management technology, and mobile terminal development technology, which can effectively utilize the data analysis of the efficiency of on-site detection of vehicle detection lines and optimize the detection process; It enables the regulatory authorities to accurately and effectively supervise the information generated by the vehicle inspection line in real time, and to develop a standardized and automated inspection process, so that each vehicle can pass the inspection safely and effectively, so that every car can safely drive on the road; The owner understands the car test results in full real-time. The overall solution can save and share various performance parameters of the vehicle diagnosis generated by each part of the indoor inspection in real time, and at the same time, through the cloud computing, the fault condition of the different terminals and the corresponding technical services are provided, which is the vehicle management department and the owner. Provide a reliable basis for comprehensive and accurate evaluation of the vehicle's performance and technical conditions.
