Application of Helixon Wireless Module in Parking Meter Guidance System
chrispeng [ad_1]
Shanxi Pingyang Heavy Industry Machinery Co., Ltd. (Shanxi Pingyang Machinery Factory) successfully launched a parking meter guidance system using Helixon IP-Link series wireless modules, which has been widely used in the main streets of many cities across the country.
The core unit in the system:
The feature of this system is that it adopts the wireless communication core technology and related products of Helixun Technology (Beijing) Co., Ltd. The Helixon IP-Link1000 short-range wireless module is embedded in each parking meter, so that each parking meter has the capability of wireless data transmission and two-way wireless communication.
System operation flow chart:
1. All meters 1 on the roadside transmit the parking and pickup information to the central node 2 wirelessly;
2. The central node transmits the data to the interface box located at each traffic intersection through long-distance wireless transmission 3;
3. The data of each meter is transmitted to the traffic command center by the optical cable 4 through the special interface device;
4. After processing 5, 6, and 7, the command center transmits it to the induction system equipment located at each intersection through the optical cable 8;
5. Display 9 information about the parking space status of the road section in the appropriate position.
The large display screen of the parking meter guidance system is installed at the main intersections in the periphery of the parking area, which can predict the number and location of free parking spaces in real time, thereby greatly reducing the blindness of drivers looking for parking spaces and the occupied time of vehicles, and improving the efficiency of parking spaces. Use efficiency.
Main features of the system:
The real-time nature of information provision – can greatly improve the intelligent level of parking meters and the scientific management of on-street parking; the bidirectional nature of data transmission – makes it possible to upgrade and expand the entire system in the future.
The main advantages of the system:
In the whole system, because the front end adopts a very mature short-range wireless module and wireless network technology, it has the following advantages:
1. The wireless communication of the meter adopts the special frequency band for wireless data transmission stipulated by the state, and there is no need to apply for the wireless frequency band during installation and use;
2. Set up a short-range wireless network between parking meters, which does not depend on the support of other wireless service providers;
3. It can be directly connected with the existing backbone network and equipment of traffic or public security, thus greatly reducing the overall investment in laying the system;
4. Since all parking meters use wireless data transmission and solar power supply, installation and movement are very convenient;
5. Real-time display of the usage status of the parking space, greatly reducing the idle time of the parking space, and the economic benefits are very obvious;
6. The parking meter with built-in Helixon wireless network module has a very powerful networking function. Users can freely install equipment at any location and increase or decrease the number of equipment according to the site environment and needs.
Helixson’s Wireless Technology Brief
