The simulated parking lot record test system is an experimental platform test system that Wuxi Internet of Things Industry Research Institute and Hunan Yongyi Technology Co., Ltd. conduct a full inspection of parking lot probes. The design, control and inspection of the space magnetic field and related software (simulating car parking actions) are completed by Yongyi Technology Co., Ltd.; the test probe and its management software are designed and completed by Wuxi Industrial Network Research Institute, forming a complete simulation parking automatic management system , To meet the full inspection of the probe equipped in the parking lot, to ensure the qualification rate of the embedded probe in the construction.
Product introduction With the rapid development of the economy, investment in infrastructure has increased. However, the rapid growth of vehicles in recent years has made the traffic situation worsening, which has become a common problem in almost all cities. The effective solution to change this traffic situation is to establish a complete traffic monitoring system in the urban traffic management department. The main goal of a traffic monitoring system is to adapt to changes in dynamic traffic conditions. That is, by collecting traffic data and transmitting it to the traffic management center for analysis in the center, according to the analysis results, the center can better control traffic by controlling vehicle entry and exit and signal lights; the center can also use these data quickly in the event of a traffic accident Take measures. At the same time, the management center can transmit the collected traffic data to the driver, which helps to alleviate traffic congestion and optimize driving routes. The use of traffic monitoring systems can improve the capacity of existing roads, coordinate the handling of unexpected traffic incidents, alleviate traffic congestion, and improve traffic conditions.Geomagnetic sensors can be used to detect the presence of vehicles and vehicle type recognition. The data acquisition system plays a very important role in the traffic monitoring system. The geomagnetic sensor is a key part of the data acquisition system. The performance of the sensor plays a decisive role in the accuracy of the data acquisition system. When a vehicle enters a berth, cutting the magnetic line of induction will cause a change in the magnetic field, and the geomagnetic sensor will then determine that the vehicle enters the berth. The geomagnetic sensor can also realize the parking guidance function. Through the comprehensive statistical analysis of the back-end system and the use of digital platforms such as WeChat, the citizens can be provided with information about the available parking spaces nearby, which can better guide the citizens to choose a reasonable parking place.The simulated parking lot recording test system is an experimental platform test system for the full inspection of parking lot probes by Wuxi Internet of Things Industry Research Institute and Hunan Yongyi Technology Co., Ltd. The design, control and inspection of the space magnetic field and related software (simulating car parking motion) are completed by Hunan Forever Elegance Technology Co.,Ltd the test probe and its management software are designed and completed by Wuxi Industrial Network Research Institute A complete set of simulated parking automatic management system meets the full inspection of the probes configured in the parking lot and ensures the qualification rate of the embedded probes in the construction.Key words:- parking
