Shanghai Renwei Electronic Technology Co., Ltd. is constantly researching and developing new products and solutions. Recently, it has released a new public transportation system solution. The specific contents of the solution are as follows:
1. System significance
Regarding bus station management, Shanghai Renweixian launched a set of management system, which mainly realizes real-time statistics of bus arrival numbers, arrival time, and real-time statistics of stations passing by on the way, and further real-time supervision of subordinate vehicles and reducing management workload. So as to achieve cost reduction and real-time vehicle management system.
1) The system provides functions such as real-time display of vehicle information, counting, timing, historical trajectory playback, etc. of the patrol inspection situation of the bus station provided by the system, so that the manager can understand the inspection situation at a glance. After the accident, whether the inspectors performed their job duties, the system also responded, indirectly protecting the inspectors’ legitimate interests.
2) Detect the arrival information of public transport vehicles. Including the arrival time of buses and the number of vehicles. Each electronic tag has a unique code, and the tag uses “active” to send information and is in a state of always sending. The electronic label information read by the handheld is stored in the buffer, and the information is uploaded to the PC or controller through “active” or “passive”. It can be used in conjunction with GPRS to perform real-time positioning of public transport vehicles, facilitating the monitoring and dispatching of public transport vehicles.
3) Different graphics, colors, labels, etc. can be used on the electronic map to make the distribution of routes, facilities and other resources clear on the map, and the functions such as loading pictures and historical repair reports can be used to make the data of each point more complete , Comprehensive, and can be searched on the map and fast positioning inquiries.
4) Real-time statistics of the time each car enters the station, so as to calculate the time it takes for each car to enter each station.
5) Through the daily maintenance work plan management module, intuitively understand the completion of the inspection plan.
6) Different colors are used to distinguish the status of hidden faults on the electronic map (untreated hidden dangers, hidden dangers being processed, hidden dangers eliminated), so that the distribution of hidden dangers can be clearly seen on the map.
2. System architecture and program description
2.1 System architecture
System network architecture
2.2 Program description
When applying this system, first install a 2.45G active electronic tag on each bus. The electronic tag is the patrol point. The staff at each station wear a handheld device. When the bus with the installed electronic tag enters the station When the time, the handheld terminal uploads the 2.45G tag information that it reads to the host computer through GPRS, which can realize the attendance record, basic information and real-time positioning of patrol personnel and vehicles.
