The invention relates to a high-density mobile monitoring system. The high-density mobile monitoring system comprises a navigation controller, and a protocol conversion circuit module, an electronic speed controller, a shipborne data transmission module and a receiver which are connected with the navigation controller. The protocol conversion circuit module is connected with more than one navigation sensor, the shipborne data transmission module is connected with a water quality monitoring probe and is wirelessly connected with a ground data transmission module, and the ground data transmission module is connected with a tablet personal computer controller; the tablet personal computer controller is connected with a remote controller, the tablet personal computer is connected with the shipborne digital image transmission module, the shipborne digital image transmission module is connected with more than one image acquisition device, and the receiver is wirelessly connected with the remote controller through a wireless network. According to the present invention, the protocol conversion circuit module and a conversion module for converting multiple protocols into an NMEA0183 international general positioning protocol are adopted, so that the standard protocol fusion of different navigation sensors is achieved, and the types of the navigation sensors can be infinitely expanded without changing and upgrading a control system CPU and a control program.

Description

technical field [0001] The invention belongs to the field of environmental protection, and relates to environmental protection water quality monitoring in inland river basins, lakes, and reservoir water environment, continuous acquisition and analysis technology of multi-parameter water quality big data, especially a high-density mobile monitoring system. Background technique [0002] The environmentally friendly unmanned ships currently on the market are mainly remote-controlled or semi-automatic route-controlled unmanned ships. The GPS positioning system, sonar detection device, and high-frequency radar on board all use their own protocols, requiring the development of a large number of redundant systems for the unmanned ship navigation control system. The integration of the rest of the protocol channels and algorithms leads to a large review of the navigation control system and the ground station system, and the difficulty of communication perception fusion. Every time a n...

Problems solved by technology

Most of the environmentally friendly unmanned ships only collect water samples, and a small part of them are equipped with simple multi-parameter probes, which cannot meet the needs of current water environmental protection work. In addition, in terms of data transmission, they basically use SIM cards to rely on The RTU of the communication operator network sends the data to the cloud platform server through the 2G or 4G network

When working in large areas of water, data cannot be collected and transmitted due to the absence of operator network signals

Moreover, the current sensor data collection frequency is low and the fastest value reaches 1 collection per minute, and at the high speed of the unmanned ship, the sampling interval of 1 minute is at least 120 meters, resulting in too sparse data sampling

If the speed is reduced, the sampling efficiency will be low and the operation time will be too long

At present, unmanned ships do not yet have the function of collecting and analyzing hyperspectral and ultraviolet-visible light data. The environmental data that can be collected is incomplete and cannot fully cover the needs of water environment management. They lack infrared equipment at night and cannot patrol at night to collect evidence.

Manual remote tracking is required in the evidence collection operation for large-scale transport ships with excessive emissions, and it is impossible to lock suspected illegal ships for automatic tracking and evidence collection
