Novel automobile detection control system scheduling algorithm

Abstract

The invention discloses a novel automobile detection control system scheduling algorithm. In order to improve the efficiency and quality of vehicle scheduling of an automobile detection control system, an existing scheduling algorithm based on a shared file and winsocket is analyzed and compared, and a novel vehicle detection scheduling algorithm combining the winsocket and a network database is provided. A dispatch table is designed and used for dispatching and state monitoring of the station machines by the main control machine. And a detailed scheduling realization process is provided, andthe detection process information of the station machine is transmitted to the main control computer through the wingsocket. Practical application shows that the algorithm improves the stability of system operation and the real-time performance and reliability of detection data transmission.

Description

technical field [0001] The invention belongs to the technical field of scheduling algorithms, and relates to a new type of scheduling algorithm for vehicle detection and control systems, specifically, a new type of vehicle detection and scheduling algorithm combined with winsockets and network databases. Background technique [0002] With the continuous and rapid development of my country's economy and society, the number of motor vehicles has shown a rapid growth trend. According to the statistics of the Traffic Management Bureau of the Ministry of Public Security, by the end of 2017, the number of motor vehicles in the country reached 310 million, of which 217 million were cars, which was comparable to that in 2016. Compared with the annual increase of 23.04 million, an increase of 11.85%. Automobile safety performance testing is one of the important measures to ensure road traffic safety. Relevant state departments attach great importance to it, and successively formulated...

Problems solved by technology

There are many problems in this method: 1. In the actual use process, it often occurs that the shared folder cannot be accessed due to virus or security policy settings, and the entire system cannot be scheduled or even paralyzed; 2. The workstation or the main control machine wheel Querying inspection information or result information consumes a lot of CPU resources, especially the main control program, which needs to process more tasks, which reduces the real-time performance of system scheduling. The more stations, the worse the real-time performance, which is not conducive to system expansion.

3. The reliability of the system is poor. Once the inspection information file of the station computer is damaged or misoperated, the system cannot operate normally

The scheduling algorithm uses the TCP handshake mechanism to ensure the reliability of data transmission, which is better than the file sharing method as a whole, but it also has the following shortcomings: (1). Both the command frame and the data frame are realized by the master computer and the workstation through winsocket In the exchange between machin
