行业动态

5月朝阳区东大桥路、朝外南街等10条大街的972个路侧占道停车位开始试行自动计时、电子收费，时间为期两个月。为了配合这一措施，试点路段的路侧停车位下方全部加装地磁传感器，一些已经尝鲜的市民便将其称为“地磁停车位”。由于它的计时标准精确到秒，可以杜绝停车管理员随意计时。

车位检测系统主要用于检测车位上是否有车，并将数据发送到后台，那么在停车场入口处的显示屏上，即会显示出当前车库里面空车位的数量。

车位检测系统是通过读取安装在车位地面下的车位探测器所采集的信号来判断停车位状态，并将各停车位的实时状态信息通过网络上传到数据中心，以实现物联管理对象(车位)、物联感知设备终端采集管理，提供车位状态信息的采集与传输功能，实现车位状态远程监控的一种系统。该系统能够大幅提高寻找车位的效率，减轻停车管理员的工作强度，有利于加强停车场的科学化管理。

车位检测系统依据车位探测器通信方式的不同，可分为有线车位检测系统和无线车位检测系统。

有线车位探测器主要由磁传感器模块组成。磁传感器主要利用车辆经过时会引起磁传感器周围的磁场变化来进行车辆检测，不受光线和天气的影响。

有线车位探测器是专门为停车场诱导、开放式停车场车位探测而设计的车位探测装置。该装置识读快速，灵敏度高，并具有极好的防串扰特性和故障检测恢复功能，可实现100％的准确识别。环境适应能力强，可满足高温、低温、雨雪等恶劣天气条件下的信息采集和处理，使用寿命达到8年以上。

有线车位探测器以CAN总线连接网关来进行通信。理论上每条CAN总线上可接100个有线车位探测器，实际连接数量可依据现场情况而定。它采取有线供电方式，供电电缆可与CAN总线同槽铺设。

随着更多重点区域的停车位加装这种地磁传感器，北京的交通部门也将逐步在网络上公布数据，方便市民出行前查询目的地周边停车位的空置率，甚至用手机便可找到某条街道空车位位置，合理安排出行。

随着经济的飞速发展，基础设施的投资力度越来越大，表现之一就是道路建设。但是由于道路建设周期一般较长，其增长远远跟不上车辆的急剧增长，使得交通状况日益恶化，这几乎成为所有城市的通病。改变这种交通现状的有效解决办法就是在城市交通管理部门建立完善的交通监控系统。交通监控系统的主要目标是适应动态交通状况的变化。

即通过采集交通数据并将其传输到交通管理中心，在中心进行分析，根据分析结果，中心通过控制车辆出入和信号灯，从而更好地管制交通；中心还可以利用这些数据在发生交通事故时迅速采取措施。同时管理中心可把采集的交通数据传给司机，这有助于减缓交通拥挤，优化行车路线。运用交通监控系统可以提高现有道路的通行能力，协调处理突发性交通事件，缓和交通阻塞，从而改善交通状况。

In May, 972 roadside parking spaces on 10 streets, such as Dongdaqiao Road and Chaowai South Street in Chaoyang District, began to try out automatic timing and electronic charging for two months. In order to cooperate with this measure, all the roadside parking spaces in the pilot section are equipped with geomagnetic sensors, which are called "geomagnetic parking spaces" by some people who have tasted fresh. Because its timing standard is accurate to seconds, parking administrators can be prevented from timing at will.

Parking space detection system is mainly used to detect whether there is a car on the parking space and send the data to the background. Then the number of empty parking spaces in the current garage will be displayed on the display screen at the entrance of the parking lot.

The parking space detection system judges the parking status by reading the signals collected by the parking detector installed under the parking space ground, and transfers the real-time status information of each parking space to the data center through the network, so as to realize the collection and management of the object (parking space) and the terminal of the perception equipment of the material link, provide the collection and transmission function of the parking status information, and realize the remote parking status. A monitoring system. The system can greatly improve the efficiency of finding parking spaces, reduce the work intensity of parking administrators, and help to strengthen the scientific management of parking lots.

Parking detection system can be divided into wired parking detection system and wireless parking detection system according to the different communication modes of parking detector.

Cable parking detector is mainly composed of magnetic sensor module. The magnetic sensor mainly uses the magnetic field around the magnetic sensor to detect the vehicle when the vehicle passes by, which is not affected by the light and weather.

Cable parking detector is a parking detection device specially designed for parking lot guidance and open parking lot detection. The device has fast reading speed, high sensitivity, excellent anti-crosstalk characteristics and fault detection and recovery function, and can achieve 100% accurate identification. It has strong adaptability to the environment and can meet the requirements of information acquisition and processing under high temperature, low temperature, rain and snow. Its service life is over 8 years.

Cable parking detector communicates with gateway through CAN bus. In theory, 100 wired parking detectors can be connected to each CAN bus, and the actual number of connections can be determined according to the site conditions. It adopts wire power supply mode, and the power supply cable can be laid in the same slot as CAN bus.

As more parking spaces in key areas are equipped with such geomagnetic sensors, Beijing's transportation departments will gradually publish data on the network to facilitate citizens to inquire about the vacancy rate of parking spaces around the destination before traveling, and even use mobile phones to find the vacancy location of a street and arrange travel rationally.

With the rapid development of economy, the investment in infrastructure is increasing, one of the manifestations is road construction. However, because the road construction cycle is generally longer, its growth is far behind the rapid growth of vehicles, making the traffic situation worse and worse, which has become a common problem in almost all cities. The effective solution to change this traffic situation is to establish a perfect traffic monitoring system in the urban traffic management department. The main goal of traffic monitoring system is to adapt to the changes of dynamic traffic conditions.

That is, by collecting traffic data and transmitting them to the traffic management center for analysis, according to the analysis results, the center can better control traffic by controlling vehicle access and signal lights; the center can also use these data to take prompt measures in the event of traffic accidents. At the same time, the management center can transmit the collected traffic data to drivers, which helps to alleviate traffic congestion and optimize driving routes. Traffic monitoring system can improve the capacity of existing roads, coordinate the handling of unexpected traffic incidents, ease traffic congestion and improve traffic conditions.
