Description of drawings

Fig. 1 is a structured flowchart of the present utility model.

Fig. 2 is the utility model working state schematic representation.

Embodiment

The output terminal of pressure transducer is connected with signal conditioning circuit, the output terminal of this signal conditioning circuit is connected with the A/D signal acquisition circuit, the output terminal of this A/D signal acquisition circuit is connected with single-chip microcomputer, this single-chip microcomputer is connected respectively with wireless communication module, RS232 interface circuit, and power module is connected with this single-chip microcomputer.

Described A/D signal acquisition circuit is used for converting the sensor signal of signal conditioning circuit output to digital signal, sends single-chip microcomputer to.

Described single-chip microcomputer is that the pressure that collects is analyzed comparison, judges the position of line clogging, will judge with monitoring result by wireless communication module simultaneously to be sent to distance host.

Described wireless communication module is used to launch the result that single-chip microcomputer is judged and detected, and adopts the analog transmissions module of 500mW, and carrier frequency is in the industrial frequency range of 450MHz.

Described power module is used to provide single-chip microcomputer employed D.C. regulated power supply.

Described RS232 interface circuit is used for the on-scene communication of single-chip microcomputer and PC.

Detection basic principle of the present utility model: at a segment pipe along a plurality of pressure transducers of pipe line arrangement, when taking place to stop up between adjacent two pressure transducer pressure positions, because supply side continues to give and pressure, and can diminish at the pipeline pressure that stops up the rear portion, therefore two pressure transducers can produce certain pressure reduction, judge between the two sensors whether stop up thus, and can accurately judge whether to report by mistake by adjacent a plurality of sensing datas.
