Abstract

The utility model discloses an automatic river level and chlorosity detector. The conventional chlorosity detection is mainly carried out by manual sampling and chemical titrimetric analysis and is easily influenced by human factors. The automatic river level and chlorosity detector comprises a data acquisition unit, a chlorine ion electrode, an ion transmitter, an ion adapter, a water level sensor, a water sampling pump, a measuring barrel, a water pump controller and general packet radio service (GPRS) communication equipment, wherein the water pump controller controls the water sampling pump to pump river water to the measuring barrel; the chlorine ion electrode is arranged inside the measuring barrel; the output end of the chlorine ion electrode is in signal connection with the input end of the ion transmitter; the output end of the ion transmitter is in signal connection with the ion adapter; the water pump controller, the ion adapter and the water level sensor are in signal connection with the data acquisition unit; and the data acquisition unit is further connected with the GPRS communication equipment. The human factors are avoided, and the automatic river level and chlorosity detector has the advantages of high contrast and high systematic property.

Description

River level and chlorosity automatic tester

Technical field

The utility model belongs to the detection technique field, relates to a kind of river level and chlorosity automatic tester.

Background technology

At present, it mainly is to adopt artificial sample and chemical titration analysis that chlorosity detects, because design is simple and crude and the working method of artificial experience type, the data that is obtained receives artificial factor to a certain extent, and comparative, systematicness are not strong.In addition, owing to be to be interrupted sampling, data is discontinuous; Integrality is not enough, is difficult to guarantee the representativeness of sample, and objective reflection chlorosity that can not be complete is with the tidal level situation of change; Make the application of data receive certain restriction, more do not reach the high reliability of hydrologic data, comparability; Therefore, need develop to high-precision automatic by manual work.

Summary of the invention

The purpose of the utility model is the deficiency of prior art, and a kind of river level and chlorosity automatic tester are provided.

The utility model solves the technical scheme that its technical matters adopted:

River level and chlorosity automatic tester comprise data gather computer, chlorine ion electrode, ion transmitter, ion adapter, level sensor, water body sampling water pump, measure bucket, water pump controller and GPRS communication facilities.

Water pump controller control water body sampling water pump is evacuated to rivers water measures bucket, in measuring bucket, is provided with chlorine ion electrode, and the output terminal of chlorine ion electrode is connected with ion transmitter input end signal, and ion transmitter output terminal is connected with ion adapter signal.

Described water pump controller, ion adapter and level sensor all are connected with the data gather computer signal, and data gather computer also is connected with the GPRS communication facilities.

The beneficial effect that the utlity model has:

The utility model has been avoided human factor, comparative, and systematicness is stronger, and can reflect objectively that chlorosity is with the tidal level situation of change.Can round-the-clock automatic on-line measurement chlorine ion concentration and current water level value, overcome the sampling that is interrupted of manual detection, data is discontinuous, the restriction that integrality is not enough.

Fig. 2 is the float type level meter fundamental diagram.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

As shown in Figure 1, the utility model comprises water body sampling, chlorine ion concentration measurement, level measuring, GPRS data transmission four parts, and this four part is supplied power by power-supply device.

The water body sampling is to start water body sampling water pump by data gather computer through the control water pump controller, fluviatic water is extracted into measures in the bucket.

The chlorine ion concentration measurement is to connect the ion transmitter by chlorine ion electrode; The chlorion transmitter is compared the small voltage signal that electrode produces through inner signal amplification, sampling and concentration relationship; The current signal of 4～20MA that output concentration is corresponding; The ion adapter converts the current signal of ion transmitter output into digital signal then, by the data gather computer signaling interface carry out data acquisition and store, demonstration and data transmission.

Level measuring is made up of data gather computer and level sensor; What wherein level sensor adopted is float type level meter, and principle of work is as shown in Figure 2.

The GPRS data transmission is made up of data gather computer and GPRS communication facilities, has wherein adopted timed sending mechanism; The time of timed sending is to be provided with through the push-button unit of service data harvester.

Through the utility model, can round-the-clock automatic on-line measurement chlorine ion concentration and current water level value, realize the chlorion on-line monitoring of rivers water.
