Fig. 1 is the structural representation that the present invention is based on vehicle-running recording system first embodiment of ZigBee;
Fig. 2 is the structural representation that the present invention is based on vehicle-running recording system second embodiment of ZigBee;
Fig. 3 is the structural representation that the present invention is based on vehicle-running recording system the 3rd embodiment of ZigBee;
Fig. 4 is the process flow diagram that the vehicle-running recording system that the present invention is based on ZigBee is uploaded data.
Embodiment
During each was used at driving recording, the drive recorder historical data of will driving a vehicle was uploaded to the data download center.And in the ZigBee network, each node can serve as three kinds of roles: coordinator, relay station and terminal device.In addition, ZigBee has defined two types equipment: full-function device FFD (Full Function Device) and simplify function device RFD (Reduced Function Device).The data download center is the coordinator, so it is full-function device FFD.Because RFD can not provide the function at network trunk station, therefore, needing drive recorder to serve as in role's the application of relay station, drive recorder should be the FFD device type.Other situation promptly can be the RFD device type, to save cost.For example, in the vehicle tracking management of carrier was used, every drive recorder should be the FFD device type, and FFD equipment can prolong the coverage of this network.And vehicle is carried out in the application of safety inspection in traffic department, every drive recorder only need possess the function of RFD equipment, i.e. and the role of terminal device can reduce the cost and the power of node like this.
In addition, the network topology structure of ZigBee is divided into three kinds: star, bunch shape and netted.Like this, the present invention can be according to the different embodiments of dissimilar formations of network topology structure and equipment.For example, in the vehicle historical data down load application for carrier, each drive recorder can adopt FFD and RFD type; Network structure can adopt star, bunch shape and netted, and coordinator's role is served as in the data download center.And in the application for traffic department's inspection road transporting safety, network structure can adopt the star structure than power saving, and each highway inspection station all is a coordinator's role.
As shown in Figure 1, in the first embodiment of the present invention, be that certain carrier carries out the network topological diagram that historical data is gathered to each vehicle.In this embodiment, adopt the ZigBee network topology structure of bunch shape.Among Fig. 1, grid diagrammatic representation host node in first embodiment, is meant data download center 101.Scattergram is represented drive recorder 103, every drive recorder be one from node.In addition, several fixed equipments are installed as relay station 102, are represented with horizontal line figure in the drawings in the parking lot.Drive recorder on each vehicle in use adopts RFD equipment cheaply, and a plurality of drive recorders belong to a relay station, forms bunch shape.Relay station is connected to the data download center.Like this, the drive recorder on each vehicle in use is sent to the data download center by near its affiliated relay station with historical data.
As shown in Figure 2, in the second embodiment of the present invention, adopt netted ZigBee network topology structure.Data download center 201 (graticule) is a host node, and the drive recorder 203 (scattergram) on each vehicle in use all adopts the higher FFD equipment of cost.Like this, each vehicle in use all is a relay station.As long as satisfy interior other node that exists of the communication context of any node, satisfy one of them node simultaneously in the communication context of host node, just can form a WLAN.Arbitraryly can historical data be uploaded to the data download center by the mode of relay from node.Equipment installation and the networking of second embodiment are comparatively simple, but cost is higher.
As shown in Figure 3, in the third embodiment of the present invention, be the scheme of Department of Communications's inspection vehicle in use.In the 3rd embodiment, adopt the ZigBee network topology structure of star.Inspection station 301 (graticules) are exactly a coordinator, and the drive recorder 303 (scattergram) on each car is a RFD equipment.This example structure is simple, and cost is lower.
Among the present invention, when utilization realizes uploading of driving historical data based on the vehicle-running recording system of ZigBee, at first can set up the ZigBee network between data download center and the drive recorder, topology of networks can be chosen as star, bunch shape or netted as required.Data download center and drive recorder can directly be formed star ZigBee network.Certainly, also relay station can be set as required, perhaps allow part or all of drive recorder serve as relay station, and then form bunch shape or netted ZigBee network.After the networking, drive recorder can be sent to the data download center by the ZigBee network historical data of will driving a vehicle.After uploading, the data download center receives the driving historical data, and can analyze inspection to these data.
As shown in Figure 4, be middle rolling car registering instrument of the present invention is uploaded process flow diagram from the driving historical data to the data download center.In step 401, drive into the communication context of host node when vehicle after, will feed back to host node to the signal power size that receives from node.In the feedback procedure, if can in the communication context of data download center, can directly signal power be fed back to the data download center as drive recorder from node.If in the communication context of certain relay station, signal power can be fed back to this relay station, this relay station is received after its signal power, according to the distance of the range data of relay station download center own, select directly this signal power to be fed back to the data download center or feed back to the data download center in the relay mode by other one or more relay stations.Relay station described here can be the drive recorder of full-function device type, also can be predefined some fixed equipment.In step 402, host node carries out analysis and judgement to these power informations because watt level information can reflect the distance of vehicle from host node, can obtain thus current distance nearest from node.In step 403, host node at first activate current distance nearest from node, allow it upload historical data.In step 404, upload the driving historical data to host node from node.In step 405, judge from node whether the driving historical data transmits and finish, if then finish upload procedure, stop to send the signal power size to host node.Otherwise turn back to step 402, continue to send the signal power size to obtain to upload the chance of historical data next time to host node.
Vehicle-running recording system and method based on ZigBee of the present invention by the ZigBee WLAN (wireless local area network), can be uploaded the driving historical data to the data download center according to wireless mode, and be easy to operate and rapidly efficient.In addition, it is big that the ZigBee network is formed the node number, and the speed of access network is very fast, can satisfy uploading of the bigger vehicle driving record data of data.
