Remote self-diagnosis system and self-diagnosis method of complex dynamic weighing sensor network

Abstract

The invention discloses a remote self-diagnosis system of a complex dynamic weighing sensing network, and relates to the field of a vehicle dynamic weighing technology. The system comprises dynamic weighing devices respectively disposed at multiple weighing areas and a server at a remote end. The dynamic weighing devices are used for dynamically weighing and recording work state information of the dynamic weighing devices and uploading the work state information of the devices to the server, and the server is used for receiving and processing the work state information of the devices and determining whether faults occur in the dynamic weighing devices. The advantages are as follows: an existing weighing area is fully utilized so that construction resources are effectively saved. The server collects the work state information of each dynamic weighing device, performs comparison analyzing on the work state information, finds out abnormal data, and determines a weighing area where a fault device is located and a fault device source according to the abnormal data, such that the time cost and the fund cost are effectively decreased.

Description

technical field [0001] The invention relates to the technical field of vehicle dynamic weighing, in particular to a remote self-diagnosis system and method of a complex dynamic weighing sensor network. Background technique [0002] The development of the transportation industry has played a positive role in promoting the construction of the national economy. At the same time, it has become an inevitable requirement to intensify efforts to rectify the phenomenon of over-limit and overloading of road transport vehicles. At present, the dynamic weighing system (Weigh in Motion, referred to as WIM) widely used on expressways can effectively control the phenomenon of vehicle overloading and overloading, and also bring reliable data support for toll collection work. It has certain defects, among which the typical situation is: in all the dynamic weighing areas that the vehicle passes, once one or more devices in one or more dynamic weighing areas fail, it will lead to serious chan...

Problems solved by technology

At present, the dynamic weighing system (Weigh in Motion, referred to as WIM) widely used on expressways can effectively control the phenomenon of vehicle overloading and overloading, and also bring reliable data support for toll collection work. It has certain defects, among which the typical situation is: in all the dynamic weighing areas that the vehicle passes, once one or more devices in one or more dynamic weighing areas fail, it will lead to serious changes in the final weighing data. Errors will directly affect the effect of overcrowding and charging results, and even cause major traffic accidents and reduce the traffic rate

The self-inspection system of the dynamic weighing system is thus developed. There will be multiple weighing areas on the entire road section, and a trading area will be set at the end of the road section. The existing self-inspection system is equipped with a server pair of detection devices in each weighing area. For detection, it is necessary to configure multiple servers, resulting in waste of resources

At the same time, when the existing self-inspection system detects devices, it needs to check each device one by one, which takes a lot of time
