Abstract

The invention provides a water quality monitoring instrument based on a controller area network (CAN) bus. The water quality monitoring instrument consists of a master control module and multiple submodules, wherein the master control module is in communication connection with the submodules through the CAN bus; the communication between the master control module and the submodules is completed according to three types of instructions, namely a task instruction, a status instruction and a characteristic parameter setting and querying instruction. According to the water quality monitoring instrument, a framed design architecture of a conventional water quality monitoring instrument system is changed, instruction communication between the master control module and each independent submodule is realized by adopting the CAN bus, and each module is in communication design by adopting a unified bus protocol. Therefore, a unified and open platform is provided for design of the water quality monitoring instrument, so that the flexibility of instrument design is improved, the instrument is conveniently maintained and upgraded, and the requirement of the market on the water quality monitoring instrument tends to a customized and flexible tendency.

Description

technical field

[0001] The invention relates to the technical field of water quality monitoring, in particular to a CAN bus-based water quality monitoring instrument. Background technique

[0002] Since my country's reform and opening up, the economy has grown rapidly, steadily and continuously, and has achieved world-renowned achievements. Accompanied by this, the pressure of environmental protection has also increased year by year, and the overall pollution is still at a relatively high level. Take the water environment as an example. At present, China's water resources are facing the threat of serious pollution. Industrial wastewater and urban and rural domestic sewage are discharged into rivers, lakes, seas, and soil in large quantities, which makes the quality of surface water and groundwater worsening, and further aggravates the pollution of water resources. The tense situation seriously restricts economic development and endangers human health. Therefore, a series o...
