In recent years, ultra limited the overload vehicles to the road, the bridge and its the attached facility serious destruction gradually was known by the society that, governed ultra along with each place limits the overload work the comprehensive implementation, various areas purchased have been massive ultra limit the overload check-out facility, ultra limited the overload vehicles to this road section to carry on the monitoring. But because the early time ultra limits the overload government work implementation quite to be dispersible, various local equipment technology condition level one, the information level is not high, only can achieve take the stand as unit's partial government effect, is unable to realize ultra limits the overload examination data effective sharing and the use, has created massive precious data draining.

As the intelligent transportation profession important constituent, ultra will limit the overload to occupy from the near future concentrates renovates to the long-term effective management transition stage, ultra will limit the overload information the network monitoring and manages imperative. Through the network monitoring and the management implementation can achieve the unification management, the reasonable cloth control, the government order unification, ceases corrupts practices, data sharing, attenion evidence goal; Meanwhile provides the basis for the center long-term road network investment construction, provides the data for the correlation department policy making laws and regulations, for the road network construction quality, the operation maintenance provides the appraisal reference.

Principle of work:

Ultra limits the overload information the network monitoring and the management system management system establishment in the user locality already in the network environment which has, uses the modular design, fuses C/S, the B/S two kind of systems structures, carries on the system disposition according to the user demand, may satisfy the province, the city, the county three levels multistage network monitor and control nmac management. The city level and county level may through appropriation local area network realization data gathering and sharing, the provincial level and the national level may use the B/S pattern realization data through the Internet network sharing and the effective use.

The system structure drawing has demonstrated the province, the city, the county three levels multistage networks information layout and examination data flowing to. In various levels system module can independently work, may carry on the function tailor according to user's demand. The system has provided the network monitoring function, joined the GIS system, the user saw not merely will be the pure examination data, but also had the entire province (city, county) respectively examines the stand the examination video frequency picture, even was allowed to depend on to the detailed law enforcement record, more vivid was direct-viewing, is advantageous for the management.

The system may through the Internet foreign issue information, the vehicle owner and each correlation department may through obtain the vehicles visit to correlation homepage the detailed information and various provinces and cities governs the ultra situation, the system network structure drawing as follows shows:

May see from on chart, on network constructing, this system can fully using the user already any network environment which has, regardless of is the special line, the wide band, the digit dialing, or the wireless network all may for the user realization network overhead construction. Moreover, already was having the check-out facility the place, we also will provide the different network according to user's network situation to turn on the connection plan. The special line accesses the net, the digit dialing accesses the net or wireless accesses the net (GPRS which China moves wireless to access the net technology, or China Unicom's CDMA wireless accesses the net technology).
