1. Product Introduction

The PXC75 series hydrological patrol vehicle is modified from a Great Wall pickup small passenger-cargo vehicle; it uses a power unit to drive the hydraulic oil pump output as the driving force for the hydrological winch; the signal processing adopts a flow measurement system. The entire patrol vehicle features stable performance, flexible and convenient operation, high automation, good mobility, and other characteristics. It is suitable for collecting hydrological data such as flood control in various rivers.

This patrol vehicle has good disassembly and assembly convenience. After the flood season, it can be freely disassembled, facilitating multi-purpose use of a single vehicle.

It is equipped with the self-developed BR.LJX-1 digital flow measurement system. The information collection and processing system integrates display, calculation, storage, processing, and printing; it features Chinese character display, good human-computer interaction function, and is equipped with a computer communication interface; the design is compact and finely made; the signal transmission depth can reach 20m, effectively solving the problem of significant signal attenuation in water. The supporting software can directly generate standard flow record forms and has data compilation functions.

The digital flow measurement system mainly includes five subsystems: (1) flow measurement subsystem; (2) flow verification subsystem; (3) flow analysis subsystem; (4) flow compilation subsystem; (5) help service subsystem.

It can measure, calculate, and display flow on-site to meet real-time flood control needs, while also having storage, analysis, query, and other functions. After measurement, analysis, compilation, and printing can be performed.
