With the continuous development of China's highway construction, the traffic flow is getting larger and larger, and with it, the number of traffic accidents is also increasing. Accidents not only cause casualties, but also cause high-speed traffic jams, how to quickly and effectively detect and handle these events, is an urgent problem, but also requires the traditional highway video surveillance to intelligent development.
As we all know, the traditional information collection mode in terms of road condition collection terminal equipment, there is generally an interface for transmission, the interface through the serial port forwarding equipment through the highway communication system and network equipment into the communication centre (monitoring centre), to achieve the collection of road condition information. This transmission mode needs to be attached to the main pipeline to provide power and transmission cable for the equipment, for special road sections such as far away from the toll station, it is not possible to provide power and transmission cable for the collection equipment, or the implementation cost is too high.
The system uses photovoltaic solar panels and small wind turbines as the main source of power supply, and converts the unstable solar and wind energy into stable electrical energy through the conversion of the wind and scenery complementary controller, which can be supplied to the monitoring equipment at the load end (ball machine, gun machine) for power supply or stored in the battery. The monitoring information obtained by the monitoring equipment is uploaded to the system's cloud for interpretation and aggregation, thus realising the collection of traffic road information.
And at this stage, through the scenery common storage monitoring power supply system on the highway, can realize the traffic road condition information collection, completely change the traditional transmission and power supply mode, really realize where need, where can realize the traffic road condition information collection. What's more, the equipment is powered by photovoltaic solar panels and small wind turbines, and transmits information to the management centre through the GPRS network, transferring the collected air visibility, weather (e.g. temperature, wind direction, wind, etc.) and other information data to the management centre for data reception, processing and storage.
Compared to the traditional utility power supply to the monitoring system, the wind and solar complementary monitoring power supply system often has greater advantages.
1. Energy saving
The system is powered by renewable wind and solar energy, resulting in a high energy consumption rate.
2. Stable and reliable
The wind-solar complementary monitoring and power supply system can be operated under different meteorological resources, wind power generation and photovoltaic power generation complement each other, greatly improving the continuity, stability and reliability of the system power supply.
3. Simple installation, economic and practical traditional utility supply monitoring system requires the construction of transmission lines, in remote areas, the construction costs are very high, with the extension of the road, but also need to set up voltage boosting system, further increasing the economic costs of loss. The wind and complementary monitoring power supply system can be self-powered, no need to lay transmission lines, convenient transportation, simple installation, with the installation, greatly reducing the economic costs of installing monitoring systems.
4. High system security
The wind and solar complementary monitoring and power supply system is an independent power supply system, the cable is completely built-in, no need to lay external cables, no need to worry about the power supply stop caused by malicious cutting and stealing of the cable. The system is also equipped with an alarm system, which will alert the controller via the IoT cloud platform once someone approaches and transmits the alarm information to the platform controller's mobile phone.
5. Easy maintenance and labour saving
The wind and solar complementary monitoring power supply system is an independent power supply system, when the system failure problems, the IOT platform will be the system failure phenomenon (such as high voltage, temperature, etc.) feedback to the platform staff, the platform staff can inform the information to the maintenance personnel for the first time to determine the problem, more targeted to carry tools to deal with. And because it is a stand-alone system, disassembly and installation are much easier, greatly reducing the work of maintenance staff and reducing labour costs.
Driven by continuous social progress, the number of motorways in China is increasing and so is the traffic flow, and with this, the number of traffic accidents is growing year on year. The increasing number of traffic accidents has not only caused a lot of economic losses, but also caused many casualties. In the face of this situation, the traditional highway video surveillance is gradually difficult to cope with: therefore the traditional highway video surveillance system to the direction of intelligent development, the establishment of highway monitoring operations management system, the implementation of monitoring operations digital, intelligent management has become the development trend and requirements.
