basic functions
The SuperRFID system sticks to the front windshield of the vehicle to prevent disassemblyRFIDLabel. Install active RFID readers 20-30 meters in front of the traffic lights in the four directions of the intersection. The readers are diagonal to the road (to expand the receiving range). When the bus approaches the intersection and encounters a green light, the current green light phase time is appropriately extended to ensure Vehicles have ample time to pass through the intersection.
When a bus approaching an intersection encounters a red light, shorten the red light signal cycle, reduce the waiting time of bus vehicles, minimize the delay time of bus vehicles at the intersection, and ensure the rapid and timely operation of urban bus vehicles to maximize their performance. The role of the carrier.
Due to the complicated road conditions, it is easy to reflect and diffract the microwave signal of the tag card. In order to prevent the same RFID card number from being read by multiple readers, which may lead to misjudgment of the request signal, it can be read through the software setting. When the RFID tag card signal is reached, the subsequent card reader will block the RFID card number within the specified time (such as 30 seconds), which can prevent the same ID number from being read by two readers on the same road, causing information errors. Sentenced.
The recognition of multiple signals is processed based on the principle of first recognition and first processing.
Electronic stop sign arrival notice function
After the intersection card reader recognizes the passing bus tag information, it can transmit the data to the background data center in real time. If an electronic stop sign is installed at the bus stop, and the information display of the electronic stop sign can be controlled in the remote background, then the data center can directly display the estimated time or distance of the bus closest to the station on the LED of the electronic stop sign. To inform the waiting person.
reliability
Due to the fast speed of the vehicle, this requires the RFID system to have extremely high card reading reliability and cannot miss the card. Shanghai Xiupai adopts leading technology to ensure that vehicles can read cards reliably in the case of fast passing, so as to give full play to the value of the system platform.
Advancement and maturity
The system design adopts advanced concepts, technologies and methods, while paying attention to the relative maturity of structure, equipment, and tools, so that the system has a greater potential for development.
Openness and standardization
In order to meet the cooperative operation ability of the technology and equipment selected by the system, the system uses standardized communication methods as much as possible, and makes the software interface and protocol public, allowing access and calling of other application software, so as to make the system open.
Scalability and easy maintenance
In order to adapt to the constant changes of the on-site environment, the system can easily expand the number of equipment; the installation and use of the equipment is also as simple as possible for easy maintenance.
