Water regimen monitoring signal processing system suitable for horizontal ADCP equipment

Abstract

The invention relates to a water regimen monitoring signal processing system suitable for horizontal ADCP equipment. The water regimen monitoring signal processing system includes a horizontal ADCP equipment body, a telemetry data collector with the function of improving remote communication, a protocol data converter capable of converting a detection digital signal into an extensible transmissiondistance and enhancing an RS-232 protocol signal with the communication function, an industrial computer with the display and alarm functions, and a data storage converter and an external storage with the function of continuously storing detection data at high capacity. The remote communication function of the water regimen monitoring signal processing system is improved, and the requirements ofoperators for lowering the on-site monitoring workload and pressure are met; and U disks can be further regularly replaced to store and accumulate water regimen historical working condition data, thethree difficulties of real-time screen display and over-limit alarm of the detection data, high capacity continuous storage and remote monitoring communication are solved, the structure is scientificand reasonable, the working mode is novel, performance is excellent, multi-aspect use requirements can be met, practicability is high, and great innovation of a water regimen information processing system is achieved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a water regime monitoring signal processing system suitable for horizontal ADCP equipment. Background technique [0002] At present, in the real-time detection of flow velocity and flow of river hydrological stations or hydrological stations, open channels, irrigation canals, etc., and the detection of hydrological information data of rivers and estuary flow fields, the ChannelMaster horizontal acoustic Doppler produced by the American RDI company is used. The water regime monitoring signal processing system based on Le current profiler (horizontal ADCP equipment for short), such as figure 1 As shown, it mainly includes a horizontal ADCP device 1, a telemetry data collector 2 with its own internal memory, and a serial port lightning protection device 3 arranged between the horizontal ADCP device 1 and the telemetry data collector 2, which has a simple structure and...

Problems solved by technology

[0002] At present, in the real-time detection of flow velocity and flow of river hydrological stations or hydrological stations, open channels, irrigation canals, etc., and the detection of hydrological information data of rivers and estuary flow fields, the ChannelMaster horizontal acoustic Doppler produced by the American RDI company is used. The water regime monitoring signal processing system based on Le current profiler (horizontal ADCP equipment for short), such as figure 1 As shown, it mainly includes a horizontal ADCP device 1, a telemetry data collector 2 with its own internal memory, and a serial port lightning protection device 3 arranged between the horizontal ADCP device 1 and the telemetry data collector 2, which has a simple structure and a small volume. It has the characteristics of small size, complete standard configuration, reliable detection data and wide application range, but it has three major shortcomings in practice: First, the random memory capacity is too small, only 4M. Due to the high rate of data update evaluation, only It meets the requirements of data storage in a short period of time, but cannot meet the storage requirements of continuous monitoring information in a long period of time; secondly, each system is independently set up at each monitoring site, except for the transmission of telemetry and collection in the standard communication protocol signal format In addition to the function of data, there is no exchange communication function for remote data receiving and sending, so it cannot meet the requirements of real-time comprehensive monitoring of the water regime monitoring department in the current environment with developed communication; the third is that the convenience of use is poor, due to the various levels of ADCP The equipment only has the function of providing real-time detection data records to the recorder through the telemetry data collector, without the function of visually displaying the working condition status and exceeding the standard alarm on the screen, which will easily affect the timeliness of finding problems, thereby affecting the overall monitoring quality

Therefore, the existing water regime monitoring signal processing system of horizontal ADCP equipment generally has disadvantages such as unreasonable structure, backward working mode, poor use convenience and insufficient time to find problems, so it is not ideal from the perspective of practicality and economy.
