Abstract
Provided is a wireless coal pile temperature measurement instrument which not only can measure the inner temperature of a coal pile, but also can allow measurement personnel not to go to the site to measure temperatures of all measurement points one by one, and thus temperature data of all measurement points can be obtained at a remote place. Data transmission between a primary instrument inserted into the coal pile for measuring temperature and a secondary instrument for displaying and outputting temperature data adopts wireless radio frequency electromagnetic wave communication mode.
Description
Art
The present invention relates to a kind of instrument measuring dump internal temperature, the data transmission of especially inserting between the primary instrument of dump thermometric and the secondary instrument of display or output temperature data adopts the electromagnetic communication mode of less radio-frequency.
Background technology
At present, known dump temperature measurer all adopts primary instrument (i.e. temperature probe) and secondary instrument (i.e. display device) wired connection, survey crew needs at the scene of primary instrument, reads dump internal temperature data by that be fixedly connected with or the interim secondary instrument connected.But, a lot of coal yard is in order to prevent self-ignition of coal pile, need the temperature data of the multiple measuring point of repetitive measurement dump every day, existing dump temperature measurer requires that survey crew must patrol and examine measurement to all measuring points at the scene one by one, manual labor amount is too heavy to such an extent as to be difficult to guarantee both quality and quantity, cause self-ignition of coal pile phenomenon to take place frequently, not only lose economic benefit also contaminated environment.
Summary of the invention
The deficiency of measurement must be patrolled and examined at the scene one by one to all measuring points in order to overcome existing dump temperature measurer requirement survey crew, the invention provides a kind of wireless dump temperature measurer, this is wireless, and dump temperature measurer can not only measure dump internal temperature, and survey crew can be made need not to arrive the on-the-spot temperature measuring all measuring points one by one, the temperature data of all measuring points just can be obtained at remote site (such as in office).
The technical solution adopted for the present invention to solve the technical problems is: in primary instrument part, temperature element is arranged in probe jacket, probe jacket connects terminal box, in terminal box, single-chip microcomputer and radio circuit are installed, temperature element is connected to the input port of single-chip microcomputer by connecting line, the output port of single-chip microcomputer connects radio circuit, radio circuit is connected with antenna, single-chip microcomputer and radio circuit and other accessory circuit are all welded on one piece of circuit board, single-chip microcomputer is by the powered battery of junction box, single-chip microcomputer is powered to above-mentioned other parts all again, single-chip microcomputer root pick software instruction drives above-mentioned other parts all to complete following operation: according to the model of temperature element, correlation method is adopted to read or accounting temperature numerical value, single-chip microcomputer sends by radio circuit and antenna Temperature numerical with the form of radio frequency electromagnetic.In secondary instrument part, antenna, radio circuit, single-chip microcomputer, output interface are connected with display screen, antenna and radio circuit receive radio frequency electromagnetic that primary instrument sends and after being decoded into digital signal, send single-chip microcomputer to, exported by standard interfaces such as RS232, RS485 after treatment, can be shown by the computer connected, also can be shown by other display screen connected.Survey crew can insert in the dump measuring point of specifying branched primary instrument respectively, then scene is left, check the measurement data of all primary instruments at remote site by secondary instrument, solve survey crew must patrol and examine measurement at the scene one by one deficiency to all measuring points.
The invention has the beneficial effects as follows, survey crew can be made need not to arrive the on-the-spot temperature measuring all measuring points one by one of dump, just can obtain the temperature data of all measuring points at remote site.Reduce manual labor amount, effectively monitoring dump heating auto-ignition, reduces economic loss and environmental pollution.

Embodiment
In FIG, temperature element (1) is arranged on the top of probe jacket (8), circuit board (9) is arranged in terminal box (7), antenna (6) is arranged on terminal box (7) outward, temperature element (1) is connected on the input port of the single-chip microcomputer (3) on circuit board (9) by connecting line (2), single-chip microcomputer (3) adopts corresponding software instruction to calculate temperature data according to the temperature element (1) of different model, single-chip microcomputer (3) connects (4) by circuit and temperature data is launched by radio circuit (5) and antenna (6).Radio frequency band generally uses the frequency range that opens for free of 433MHZ and 2.4GHZ.Because only have to measure and could effectively monitor self-ignition of coal pile situation more than the temperature of 1 meter of degree of depth inwards from dump surface, so the depth sounding of probe is generally all more than 1 meter, point for measuring temperature is arranged on probe tip.Conveniently probe is inserted dump, so probe tip is often made into taper shape.When the material of terminal box is metal material, antenna must be arranged on outside terminal box, is shielded by terminal box to avoid radio magnetic wave.
In fig. 2, circuit board (14) is arranged in terminal box, antenna (12) is arranged on outside terminal box, computer or other display screen (15) are arranged on outside terminal box, antenna (12), radio circuit (11), single-chip microcomputer (10), output interface (13) and computer or other display screen (15) are linked in sequence, antenna (12) senses electromagnetic wave, radio circuit (11) is decoded, single-chip microcomputer (10) processes decoded data, and according to certain agreement by output interface (13) output signal, computer or other display screen (15) show data.
Claims (1)
1. a wireless dump temperature measurer, primary instrument inserts dump internal measurement temperature, secondary instrument is exported measuring tempeature or is shown by display screen by interface, it is characterized in that: the data transmission of inserting between the primary instrument of dump thermometric and the secondary instrument of display or output temperature data adopts the electromagnetic communication mode of less radio-frequency.
