Method and system for vehicle dispatching and based on wireless communication network

Abstract

The invention discloses a method and a system for vehicle dispatching and relates to the field of wireless monitoring and information technology. To overcome limitations that a traditional vehicle dispatching method is small in covering range, low in positioning system cost performance, single in interactive mode, high in construction cost and high in using cost, network location technology or terminal location technology is adopted in a compatible mode, accurate maintenance is performed according to road attributes, a vehicle dispatching request is launched through a wireless communication terminal or the internet, through ringing trigger of a phone call of a vehicle mounted terminal from a dispatching side, corresponding set voice notification is played by the vehicle mounted terminal according to a distinguished trigger calling number to notice personnel in vehicles and then according to the trigger calling number, a compulsory communication method or a selective communication method is selected so that establishment of unstructured supplementary service data (USSD) communication connection between the vehicle and the dispatching side is launched automatically by the vehicle mounted terminal. According to the interactive communication connection, multi-side communication among the personnel in the vehicle and the dispatching side is achieved so that vehicle dispatching is achieved.

Description

technical field [0001] The invention relates to remote wireless monitoring technology, LBS network positioning technology, wireless communication technology, network communication technology, software technology, and specifically refers to a vehicle scheduling method and system. It belongs to the field of information technology. Background technique [0002] At present, the known vehicle dispatching methods and systems refer to the vehicle dispatching methods and systems in which vehicle users or network operators use GPS (Global Satellite Positioning System) technology to provide location-based services or intercom services to users of the business. For example, the taxi GPS call (telephone call) system that has just begun to be piloted in China. Vehicle dispatching system functionally includes positioning system and command system. [0003] For the positioning system: First, there are two ways for the GPS positioning system of the vehicle dispatching unit: one is to buil...

Problems solved by technology

This will in turn create a problem with the scope of work: the location information (latitude and longitude / altitude) generated by the positioning terminal of the dispatched vehicle through the satellite receiver must be transmitted to the positioning center (dispatching center) to complete map comparison and analysis

[0007] However, the above methods have many limitations: one, if the public wireless communication network is used for intercom calls, the cost of the calls is high, and it is seriously affected by the noise in the car; two, if the self-built wireless communication network is used for intercom calls, the signal The range is limited, there are many blind spots, the investment in network construction is large, and it is also disturbed by the noise in the car; 3. If the dispatch center directly dials the mobile phones of the personnel in the car for dispatching and commanding, it cannot use broadcast-style calls, but can only use The point-to-point communication method results in high communication costs, poor timeliness, waste of manpower, and affects driving safety at the same time; 4. If you directly send text messages to the personnel in the car for scheduling, in addition to the above disadvantages, because ordinary text messages do not guarantee QoS (Quality of Service), especially the delay characteristics of SMS has brought many adverse effects to the vehicle dispatching application
