Description

The soil data acquisition unit that is used for earth exploration

Technical field

The utility model relates to a kind of data collector that is used for earth exploration.

Background technology

Be that the scientific research personnel carries out the equipment that geological research often can be used on the seismic prospecting car.Often be equipped with the soil data acquisition unit onboard, but existing soil data acquisition unit is simple in structure, but need uses very inconvenient from just carrying out the DATA REASONING of soil after car is moved ground to.And this data acquisition unit can only video data, but can not store data, needs the timely record of scientific research personnel, can not be transferred to the researchist to data in real time simultaneously.

Summary of the invention

The technical matters of mentioning in order to solve in the background technology; The utility model provides a kind of soil data acquisition unit that is used for earth exploration; After this kind data acquisition unit is applied on the seismic prospecting car, can under general geologic condition, directly measure, not only can show the data of surveying simultaneously; And can realize mass memory, can also be with real time data through the wireless server that is uploaded to of the GPRS communication module of inside.

The technical scheme of the utility model is: this kind is used for the soil data acquisition unit of earth exploration; Comprise the Instrument shell that has power lead and display screen; And power module; Its unique distinction is: said Instrument shell is outer to be fixed with the several expansion pipe through hinge, is fixed for the sensor of measured soil data on the top of draw-tube, is used for the signal cable of output transducer information to be positioned at draw-tube; The internal storage interface module that said soil data acquisition unit also comprises the major and minor control module that constitutes by STC12C5A60S2 type single-chip microcomputer, be made up of the CH375 chip, internal memory module, the external memory interface module and the GPRS communication module that constitute by the CH375 chip; Wherein, all be integrated with in the said major and minor control module A/D converter to sensor acquisition to data-signal carry out analog to digital conversion; Said main control module is passed through the internal storage interface module stores to the data after handling in internal memory module, and communicates with said GPRS communication module; Said sub-control module and said main control module are carried out exchanges data, export the data that said main control resume module is crossed through the external memory interface module; Said GPRS communication module transmits data on flows through mobile communications network in real time.

The utlity model has following beneficial effect: this kind is used for the soil data acquisition unit of earth exploration, and the sensor that is used for the measured soil data is fixed on the top of draw-tube, and draw-tube is to fix on the Instrument shell through hinges fixing; So; When needs measured soil data, only need draw-tube be screwed out the back and elongate, just can sensors such as the temperature that is disposed, humidity, resistivity directly be inserted and measure in the soil; Therefore, need not to move instrument from car again.In addition, in instrument, have some, therefore, not only can show the various soil data that tested out, and exterior capacity all reaches the memory module of 8G in can driving respectively, thereby realized mass memory measurement data because have memory module interface.In addition; This kind data acquisition unit can also be with the measurement data that obtains in real time through the wireless server that is uploaded to of the GPRS communication module of inside; Make that being positioned at the indoor researchist of Long-distance Control can monitor the various parameter situation of soil in real time, thus the data that acquisition can supply be analyzed.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

By shown in Figure 1; This kind is used for the soil data acquisition unit of earth exploration; Comprise the Instrument shell 4 that has power lead 8 and display screen 2, and power module, its unique distinction is: be fixed with several expansion pipe 6 through hinge 7 outside the said Instrument shell 4; Be fixed for the sensor 5 of measured soil data on the top of draw-tube, be used for the signal cable of output transducer information and be positioned at draw-tube 6.The internal storage interface module U4 that as shown in Figure 2, said soil data acquisition unit also comprises the main control module U1 that constitutes by STC12C5A60S2 type single-chip microcomputer, sub-control module U2, be made up of the CH375 chip, internal memory module U18, the external memory interface module U3 and the GPRS communication module U5 that constitute by the CH375 chip; Wherein, all be integrated with A/D converter in the said major and minor control module data-signal that sensor 5 collects is carried out analog to digital conversion; Said main control module U1 is stored in the data after handling among the internal memory module U18 through internal storage interface module U4, and communicates with said GPRS communication module U5; Said sub-control module U2 and said main control module U1 carry out exchanges data, export said main control module U1 data processed through external memory interface module U3; Said GPRS communication module U5 transmits data on flows through mobile communications network in real time, and is as shown in Figure 1, antenna 1 is set so that cooperate the work of GPRS communication module on the housing.

During practical application, can dispose multiple parameter sensors, for example promptly dispose 4 in this example, thereby make it have 4 circuit-switched data input channels, can gather 4 circuit-switched data simultaneously.No. 4 sensors of this example are provided with, and are divided into temperature, humidity, resistivity and pH measurement sensor, certainly are provided with separately as required.

In addition, for guaranteeing the reliability of power supply, existing power supply module is transformed, made its tool use the dual power supply input end, wherein the input end of primary power draws from vehicle power, and the input end of standby power supply comes from the lithium battery that is installed in the housing.

During application, various sensors will be passed to the A/D converter in the main control module U1 to the current signal that the simulating signal that collects is transformed into 4-20mA, afterwards, are sent in the main control module U1 and carry out data processing through becoming digital quantity after mould/number conversion.After accomplishing data processing, be stored among the internal memory module U18 through internal storage interface module U4 again.When the user wants to check the data of internal memory module U18, can realize that the module of main control simultaneously U1 give sub-control module U2 through serial communication with data transfer through operation keyboard, the U2 of sub-control module then shows data on display screen.In like manner, when with external memory storage U19 with after external memory interface module U3 is connected, also can the data among the internal memory module U18 be copied among the external memory storage U19 through keyboard operation.Also can under the effect of main control module U1, send the data among the internal memory module U18 to managerial personnel through GPRS communication module U5, carry out remote monitoring and control.
