Description
Technical field
The present invention relates to underground coal mine liquid level sensor field, be specifically related to a kind of coal Mine-used I. S ultrasonic liquid level sensor.
Background technology
At present, the water bunker level height major part of domestic underground coal mine uses the detection method of throw-in type liquid level sensor, detection inductive head is placed on the bottom of sump, becomes actual water level by the conversion pressure experienced.But the water of underground coal mine is very muddy, the aperture of inductive head surrounding is easy to be blocked by the impurity of sewage, causes water level monitoring fault.
Summary of the invention
For overcoming described deficiency, the purpose of this utility model is to provide a kind of coal Mine-used I. S ultrasonic liquid level sensor in underground coal mine work.
The utility model solves the technical scheme that its technical matters adopts: a kind of coal Mine-used I. S ultrasonic liquid level sensor, comprise processor for ultrasonic wave, loudspeaker nozzle, form, shell, transducing head, wiring board, described processor for ultrasonic wave inside is provided with transducing head, described processor for ultrasonic wave upper end is provided with shell, described shell side is provided with loudspeaker nozzle, described shell is provided with form, described enclosure is provided with wiring board, described wiring board is provided with single-chip microcomputer, transformer T1 in described processor for ultrasonic wave, resistance, the electrical equipments such as electric capacity epoxy resin encapsulation, to reach the object of essential safety, outwards lead to the signal wire of single-chip microcomputer, processor for ultrasonic wave takes into full account load energy, reduce the capacitance of components and parts, inductance value.
Further, described single-chip microcomputer adopts ATMEGA1284 single-chip microcomputer.
Further, the LED display be connected with single-chip microcomputer is provided with inside described form.
The utility model has following beneficial effect: the present invention thoroughly solves the drawback that coal mine survey water level uses submerged sensor blocked, makes ultrasonic liquid level sensor reach essential safety in the application in colliery.Be widely used in the measuring system of coal mine underground sump water level, temporary drainage point water level.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.
According to Fig. 1, Fig. 2, Fig. 3, a kind of coal Mine-used I. S ultrasonic liquid level sensor shown in Fig. 4, comprise processor for ultrasonic wave 1, loudspeaker nozzle 2, form 3, shell 4, transducing head 5, wiring board 6, described processor for ultrasonic wave 1 inside is provided with transducing head 5, described processor for ultrasonic wave 1 upper end is provided with shell 4, described shell 4 side is provided with loudspeaker nozzle 2, described shell 4 is provided with form 3, described shell 4 inside is provided with wiring board 6, described wiring board 6 is provided with single-chip microcomputer, transformer T1 in described processor for ultrasonic wave 1, resistance, the electrical equipments such as electric capacity epoxy resin encapsulation, to reach the object of essential safety, outwards lead to the signal wire of single-chip microcomputer, processor for ultrasonic wave 1 takes into full account load energy, reduce the capacitance of components and parts, inductance value.
Further, described single-chip microcomputer adopts ATMEGA1284 single-chip microcomputer.
Further, the LED display be connected with single-chip microcomputer is provided with inside described form 3.
During work, first single-chip microcomputer controls transducing head 5 output ultrasonic wave signal, the time that record sends, then wait-receiving mode ultrasonic signal, if receive, record time of reception, calculate ultrasound wave according to the transfer rate of sound wave and touch the mistiming after tested plane, calculate air distance, total range-air distance transform is gone out actual liquid level value.If do not receive ultrasonic signal, then enter the transmission of next round.If the gap data calculated several times adjacent is comparatively large, then need to carry out filtering process.
For taking into full account the change of the sound wave that the change of temperature causes and the velocity of sound, coal Mine-used I. S ultrasonic liquid level sensor built-in temperature sensor AD592 carries out temperature detection, hyperacoustic velocity of propagation is by the impact of atmospheric density, density is larger, velocity of propagation is faster, and atmospheric density and temperature have substantial connection, so during temperature variation, the velocity of sound also changes.According to the dynamic relationship of temperature and the velocity of sound, guarantee that the liquid level calculated is by the impact of measured object environment temperature.
The liquid level data calculated, through the display of Q3, Q4, Q5, Q6 driving LED, shows by single-chip microcomputer.For considering the essential safety externally exported, externally selecting the way of output of 4-20mA, being convenient to the collection substation of linking automation system.
The utility model is not limited to described embodiment, and anyone should learn the structure change made under enlightenment of the present utility model, and every have identical or close technical scheme with the utility model, all falls within protection domain of the present utility model.
Technology, shape, structure part that the utility model is not described in detail are known technology.
