Problems solved by technology

[0004] The above invention is still unable to realize timely and efficient backup for the driving data of the bus, but only for the routing discovery stage of the ad hoc network, so as to ensure that the routing request can be safely forwarded to the destination node; therefore, it is necessary to provide a bus-based Method, system and client for information backup of vehicle self-organizing network, so as to solve the above-mentioned problems

Embodiment 2

[0128] On the basis of the foregoing scheme, embodiment two of the present invention is:

[0129] Assume that at 8:00 on a certain day, bus A is attacked by terrorists at latitude and longitude (X, Y), and the attack causes unrecoverable damage to the disks of the bus that store information such as cameras and bus operating conditions. Query all buses that have overlapping routes with bus A; at 8:00 on the same day, take the latitude and longitude (X, Y) as the center of the circle, and take 100m as the radius (100m is the maximum distance of the ad hoc network, this example is set to 100m, you can Adjust according to the specific situation) whether there is a bus within the range; if so, query the current location of the bus, the relevant personnel go to the current location of the bus, export the backup data, and according to the attacked bus A Retrieve the license plate and obtain the backup information for a period of time before 8:00. If the amount of information is insu...

Embodiment 3

[0130] see Image 6 , on the basis of the above scheme, the third embodiment of the present invention is:

[0131] An information backup system based on the bus ad hoc network, including:

[0132] The collection module 1 is used for the first bus node to sequentially collect two or more driving data packets named after the bus number and the collection start and end time according to the preset collection period;

[0133] A storage module 2, configured to store the driving data packet to the sending buffer unit of the first bus node;

[0134] The first obtaining module 3 is used for the first bus node to obtain a line of data packets from the sending buffer unit;

[0135] The second obtaining module 4 is used for the first bus node to obtain the signal strength of other bus nodes in the ad hoc network constructed by it;

[0136] Determining module 5, for determining the second bus node with the highest signal strength;

[0137] Establishment module 6, is used for establish...

Embodiment 4

[0156] see Figure 9 , the fourth embodiment of the present invention is:

[0157] A client for information backup based on the bus ad hoc network, including:

[0158] The preset unit 22 is used to preset the collection period;

[0159] The second collection unit 23 is used to sequentially collect two or more driving data packets named after the bus number corresponding to the client and the collection start and end time according to the preset collection period;

[0160] a storage unit 24, configured to store the driving data packet to the sending buffer unit;

[0161] The first acquiring unit 25 is configured to acquire a row of data packets from the sending buffer unit;

[0162] The second obtaining unit 26 is used to obtain the signal strength of other client nodes in the ad hoc network constructed by it;

[0163] Determining unit 27, configured to determine the client node with the highest signal strength;

[0164] An establishment unit 28, configured to establish a ...

Abstract

The present invention provides an information backup method, a system and a client based on a bus ad hoc network. The method comprises the steps of: sequentially acquiring more than two driving data packets by a first bus node according to a preset acquisition cycle; acquiring the signal strength of other bus nodes in the ad hoc network constructed by the data packets; determining a second bus node with the highest signal strength; establishing a wireless transmission channel; transmitting a driving data packet to the second bus node; transmitting a confirmation message to the first bus node by the second bus node after successfully receiving the driving data packet; and continuously acquiring the next driving data packet until all the driving data packets are successfully transmitted. The information backup method, the system and the client realize the backup of driving data, and when local driving data are lost, the required driving data can be acquired accurately in time according to driving tracks of a bus, thereby realizing accurate restoration of the scene of an accident.

Description

technical field [0001] The invention relates to a method, system and client for information backup based on the bus ad hoc network. Background technique [0002] With the application and promotion of intelligent and information technology in the automotive industry, intelligent vehicle operation management vehicle equipment and vehicle video monitoring equipment have been widely used in various vehicles. For the public transportation industry, based on the on-board equipment, a large amount of driving information can be obtained during the operation of the bus, and the operation of the vehicle can be recorded in real time. In the existing technology, the important driving information collected by the bus through the on-board equipment needs to be sent to the background of the system for storage after entering the bus terminal; however, vehicle accidents, vandalism, terrorists, etc. Vehicle deflagration, incineration and other damage caused by attacks and other reasons, and ...
