Distributed vehicle safety performance detection system can be extended to have remote networking capabilities

The characteristics of the electric vehicle safety automatic detection line:

(l) Integrate vehicle inspection, vehicle management and financial management into one.

(2) Adopting the station setting to make the system more stable and reliable.

(3) Integrate IC card into people's system, that is, create IC card intelligent recording system and IC card instant inquiry system. The former uses IC card instead of manual registration on the inspection line, which greatly improves the speed and accuracy of inspection, and the latter only Need to insert the IC card into the read-write machine, the detection data of the car can be quickly presented, which overcomes the shortcomings of manual query misoperation and slow query speed.

(4) Add advanced electronic voice technology to provide an automatic guidance system for on-site inspections, so that the interaction ability is stronger and more vivid

The distributed vehicle safety performance detection system can be extended to have remote networking capabilities. For example, on the basis of the current network, only one multi-protocol router can be installed. Through the dial-up telephone network, it is possible to achieve access to relevant data over a wide area, and achieve information exchange and resource sharing. The system has passed the acceptance of the Ministry of Public Security and the State Bureau of Technical Supervision. It is currently operating in good condition.

Duplex Filters


 Duplex filters, also called double-barrel return pipeline filters, are composed of two single-barrel filters and two six-way reversing valves, which have simple structure, easy to use, and with by-pass valve and filter core pollution clogging transmitter, in order to ensure the safety of the system.


The double-barrel filter is mainly installed on the return pipeline of the hydraulic system. Various kinds of dirt such as abrasive particles produced by various hydraulic components in the working process can be intercepted by setting the Oil Filter of the return pipeline to avoid returning to the fuel tank again. Inhaled again by a hydraulic pump. The allowable pressure difference of the oil filter in the return pipeline is 0.3 ~ 0.5mpa. according to the different pressure level. The accuracy is determined according to the oil contamination requirement. In the working process, when the filter core is clogged to a certain extent and the filter core needs to be cleaned or replaced, it is necessary to stop the mainframe operation to replace the filter element, which is not only a waste of time but also can not meet the needs of continuous operation of the main engine. The double-barrel filter can effectively solve the defect of single-barrel filter and can clean or replace the filter core without stopping to ensure the mainframe work normally and continuously. When one filter core is blocked and needs to be replaced, it is not necessary to stop the mainframe operation. Just open the pressure balance valve and turn on the reversing valve. The other filter can take part in the operation and then replace the blocked filter element
