Intelligent public traffic system

Abstract

The system comprises wireless communication dedicated network and computer software management system. The dedicated network is composed of dedicated frequency channel, base station equipment, link transmission equipment and bus carried terminals. Computer software management system consists of subsystem of electric arranging buses and subsystem of dynamic monitoring. The system provides advantages of very low running expenses, large user capacity at single frequency point, fast information response speed, powerful linking ability of base station including individual call, group call and cluster call, automatic statistics for passenger flow of getting on and getting off as well as updating and down loading bus carried data wirelessly. Running condition of wireless network and fault analysis are monitored remotely. Computer software management system includes multifunctional subsystems assemble by user. The invention is suitable to areas of materials circulation, special vehicle etc.

Problems solved by technology

[0002] At present, the wireless communication technology used in the intelligent public transportation system is mainly divided into three categories on the market. One is the short message data transmission system of the public network (GSM) or the GPRS data transmission system. The disadvantages are: the network delay of data transmission is uncertain, When the network is congested, the delay will be very long, up to several hours; the system is designed for public applications and cannot be used for the special application of public transport users. If the system is installed on all public transport vehicles in a certain city, it will be There is network congestion and it is difficult to apply in a large area; the system cannot realize the one-to-many scheduling call function, because the system is designed for personal private calls; users need to bear a certain usage fee, and the user's later operation burden is heavy It also has the disadvantage of uncertain network delay

[0003] The second is the trunking system. The original design of the system is for voice scheduling. It is characterized by a strong scheduling function. Its disadvantages are: the network connection time is long, and it is not suitable for bus applications where a large number of users frequently send short data data. Transmission; the construction cost is high, and the equipment of the trunking system is mostly foreign products, which are expensive and not suitable for China's national conditions; the user capacity of a single frequency point is small, generally about 100 users

[0004] The third is the combination of the short message data transmission system of the public network (GSM) and the paging system. The system uses the short message data transmission system of the public network (GSM) when the vehicle terminal uploads data, and uses the paging system ( Mainly to save the usage fee of the public network), this scheme not only has the disadvantages of the first scheme, but also increases the construction cost of the user, increases the complexity and cost of the vehicle terminal equipment, and increases the inconvenience of the whole system. reliability

[0005] The vehicle-mounted terminal generally only has the functions of dispatching short message reception and feedback, automatic reporting of vehicle position and voice communication. The station reporting is manually operated by the driver, which increases the workload of the driver and also easily distracts the driver. The specific operating status of the vehicle, passenger flow Such problems cannot be reported, the network determines that the command response time is long, and the general command response time of the public network needs to be delayed, and it must be at least 3 seconds if there is no delay

[0006] Computer software management system At present, there is no integrated management software system that combines wireless communication technology and comprehensively manages various functional departments of the bus yard at home and abroad. Only a single management system is developed, such as operation management, production management, dispatch management, etc.

[0007] In addition, the electronic stop sign is generally received by the control center after receiving the GPS information and GSM text message of the vehicle, determining the position according to the algorithm, and sending the information to the electronic stop sign in the form of POCSAG and FLEX paging signals or short messages. The information of the electronic stop sign must come from the control center. Center, increased system data flow
