Description
Technical field
The utility model relates to a kind of Level Detection framework, particularly a kind of distributed intelligence liquid level radio detection framework.
Background technology
Level Detection is very general in commercial production, and application is also very wide, as the detection of water level from the beginning, the measurement of the oil level of petroleum pipe line and storage tank etc.Existing detection mode is that instrument detection liquid level is installed in measured point such as pipeline, storage tank at the scene, the data presentation that sensor records is adjusted liquid level on the instrument display screen or be printed on the recording chart when the operative employee requires to close or open valve according to liquid level when the scene is patrolled and examined.Other have some large-scale companies by DCS with the detected data transmission of field instrument to the computer screen of Master Control Room, the operative employee still must arrive the Field adjustment valve makes liquid level meet the requirements of data.Though this detection mode has certain operability, but it is very inconvenient, untimely, and because of each conventional instrument Level Detection is subjected to influence and operating personnel's manual operation at the scene of different medium performance and environment temperature, climate change, not accurate enough to the detection of liquid level.
The utility model content
The utility model overcomes the defective of prior art, distributed intelligence liquid level radio detection framework is provided, utilizes the one-chip machine port control function, realized that the liquid level real-time radio detects, have easy to operate, reliable advantage, reach the effect that accurately, in time detects liquid level.
The technical scheme that realizes above-mentioned purpose is: a kind of distributed intelligence liquid level radio detection framework, comprise first wireless transceiver and second wireless transceiver that are used for radio communication, second wireless transceiver has numeric keypad and the 2nd PIC single-chip microcomputer, this liquid level detection system also comprises a PIC single-chip microcomputer, infrared sensor module, digital display module, the discharge water submersible pump and the submersible pump that draws water, wherein:
The one PIC single-chip microcomputer respectively with described first wireless transceiver, infrared sensor module, digital display module.The submersible pump that discharges water links to each other with the submersible pump that draws water, and the embedded AD converter of a described PIC single-chip microcomputer.
The beneficial effects of the utility model are: the utility model has realized that the radio detection Distributed Liquid Level detects, be that distributed wireless detects liquid level and can adjust liquid level according to actual needs at any time, realize various hardware controls functions by making full use of one-chip machine port, it has easy to operate, reliable advantage, reaches the effect that accurately, in time detects liquid level.
Description of drawings
Fig. 1 is the theory diagram of distributed intelligence liquid level radio detection framework.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, the utility model distributed intelligence liquid level radio detection framework comprises first wireless transceiver 2 and second wireless transceiver 3 that are used for radio communication, and wherein second wireless transceiver 3 has numeric keypad and the 2nd PIC single-chip microcomputer.The utility model liquid level detection system also comprise a PIC single-chip microcomputer 1 (adopt model: PIC16F877), infrared sensor module 5, three figure place sign indicating number display modules 4, the discharge water submersible pump 6 and the submersible pump 7 that draws water, wherein:
The one PIC single-chip microcomputer 1 links to each other with the submersible pump 7 that draws water with first wireless transceiver 2, infrared sensor module 5, three figure place sign indicating number display modules 4, the submersible pump 6 that discharges water respectively, and a PIC single-chip microcomputer 1 embedded 12 bit A/D converters.
Pour into an amount of water in the present embodiment pallet 8, the high about 100mm of benchmark carries out regulating water level control, variation range 90～120mm with a PIC single-chip microcomputer 1.
Present embodiment adopts infrared sensing module 5 to carry out water level detecting, and this project is used the infrared distance sensor GP2D12 of Sharp, detects distance range 10～80mm.(1.4～2.4V), resolution is also just high more when the aanalogvoltage rate of change maximum that detects distance output when 10～20mm changes for this infrared sensor module 5.The present embodiment range of stage is 80～130mm, in order to reach best measurement effect, infrared sensor module 5 can be set up from tray bottom 180mm, and infrared sensor module 5 sensing ranges can be dropped among 10～20mm variation.When water level during in 80～130mm range, the water surface in the pallet 8 and the variation range between the infrared sensor module 5 are exactly 100～150mm like this.
The principle of work of theory diagram is: according to pallet 8 water level practical requirements, numeric keypad input by second wireless transceiver 3, second wireless transceiver 3 that utilization has the 2nd PIC single-chip microcomputer sends, and is presented in the three figure place sign indicating number display modules 4 after being received by first wireless transceiver 2.Infrared sensor module 5 detects current water level in the pallet 8 in real time, the one PIC single-chip microcomputer 1 utilizes its 12 embedded bit A/D converters to detect the simulating signal of infrared sensor module 5 outputs, and go control the discharge water submersible pump 6 or submersible pump 7 work of drawing water in view of the above, reach preposition up to water level, submersible pump quits work.
Of particular note: above embodiment in conjunction with the accompanying drawings has been described in detail the utility model, and those of ordinary skill in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute the qualification to utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
