Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0028] figure 1 A method for distributed storage of monitoring video on a bus according to an embodiment of the present invention is schematically shown. Such as figure 1 As shown, the method includes:
[0029] Step S101: configure wireless AP (Access Point, access point) nodes and storage nodes in the coverage area of the bus network, and configure a wireless access controller on the bus.
[0030] Divide the coverage area of the bus network into grids, calculate the density of the bus network in each grid, and thus determine the number S of wireless AP nodes in each grid i . Preferably, the geographical area is divided into length and width are 1km, area is 1km 2 There are many grids, and the bus network density δ of each grid is calculated i . Among them, δ=L / F, L is the total length of the road centerline with bus lines (unit is km), F is the ur...

The invention discloses a bus monitoring video distributed storage method, which is characterized by comprising the steps of: arranging wireless Access Point (AP) nodes and storage nodes in a public transportation network coverage area, and arranging a wireless access controller on a bus; establishing a wireless network with the corresponding wireless AP nodes through the wireless access controller; obtaining original video files through a video monitoring all-in-one machine terminal on the bus, performing video sampling and splitting on the original video files, and generating small video files; and sending the small video files to the corresponding storage nodes for storage through the established wireless network. The invention also discloses a bus monitoring video distributed storage system. Through the method and the system of the invention, the distributed storage of bus monitoring videos based on the wireless transmission can be realized, and the valuable videos can be stored in time before terminal physical damages happen.
Description
technical field [0001] The invention relates to a wireless mobile distributed real-time storage technology, in particular to a method and system for distributed storage of monitoring video on a bus. Background technique [0002] Since June 2013, bus accidents in Xiamen, Guiyang, Yibin, Changsha, Hangzhou, Guangzhou and other places have occurred continuously, and various arson and explosion cases have occurred frequently. And because the vehicle-mounted video recorder is basically not equipped with fireproof and heat insulation devices, the hard disk recording the video is damaged under high temperature, so the truth of the incident is often difficult to investigate. At present, there is no fire-resistant vehicle-mounted equipment on the market. To save surveillance video at high temperatures, each vehicle-mounted video recorder can only be transformed into a black box similar to an airplane. However, the cost is quite expensive, and the feasibility is not high, so it is dif...
