Abstract

The invention provides a radio wave tunnel scenograph which comprises a radio wave receiver and a radio wave transmitter, wherein a plurality of receiving coils with antenna modules are arranged between the receiver and the transmitter; the antenna modules comprise singlechips, A/D (analog to digital) conversion modules and 2.4G radio communication modules; the A/D conversion modules and the 2.4G radio communication modules are connected with pins of the singlechips; the receiver comprises a singlechip, a data storage module and a 2.4G radio communication module; and the data storage module and the 2.4G radio communication module are connected with pins of the singlechip. According to the radio wave tunnel scenograph, the data collection quantity of an identical receiving point is increased greatly; the accidental error of single data is reduced; the interpretation accuracy is improved; the background interference can be eliminated effectively due to the fact that the data is measured before the transmitter transmits; the working strength of an operator of the receiver is reduced greatly; and the radio wave tunnel scenograph is high in interference resistance and is applicable to popularization and application.

Description

The radiowave underground electromagnetic wave perradiator

Technical field

The present invention relates to a kind of radiowave underground electromagnetic wave perradiator, belong to the detecting devices technical field.

Background technology

As everyone knows, in the coal production process, verify in advance the tectonic structure of coal-face to guarantee coal mining, particularly combine carrying out smoothly of adopting, it is the vital task of mine shaft geology work, along with improving constantly of mining mechanization degree, clear tectonic structure and geological phenomenon are visited in requirement before exploitation degree is also more and more higher; The radiowave underground electromagnetic wave perradiator has carrying portable, simple to operate, required staff less (only needing 4-5 people), resolution characteristic is strong and the characteristics such as work efficiency height, be subject to insider's attention all the time, be widely used in the fields such as coal and engineering exploration.

The radiowave underground electromagnetic wave perradiator of present domestic use mainly uses the medium frequency electric magnetic wave of single-frequency as excitation signal, during work, radio wave transmission machine and receiver are split both sides with workplace, common observed pattern is: transmitter is pressed fixed step size pointwise emission along the tunnel, receiver over there tunnel receives with pointwise in the certain limit, amplitude A and phase value θ that the electromagnetic wave field strong component in coal seam is passed in measurement infer the geological condition in the workplace with this.

The working method of radiowave tunnel scenography generally is divided into: fixed point emission, fixed point receive, synchronous scanning.

So-called fixed point emission working method is exactly that transmitter is fixed in certain position, and the receiver in another tunnel moves forward and backward and detects the signal that transmitter transmits; Then with above-mentioned opposite, transmitter moved emission, the receiver fixed test during fixed point received; The synchronous scanning working method is that transmitter and receiver is kept synchronizing moving in two tunnels.

Existing radiowave underground electromagnetic wave perradiator adopts between receiving antenna and the receiver and is connected by cable, and the field intensity value that records is sent to receiver by wired mode, the recipient bear receiver in the acceptance point position image data one by one.The weak point of the method is: 1, operating personnel's workload is large; 2, each emission, each acceptance point only gathers a secondary data; Environmental background value when 3, not having detection not launch can't be rejected interfering data.

Summary of the invention

For above-mentioned weak point of the prior art, the invention provides the radiowave underground electromagnetic wave perradiator that a kind of operating personnel's workload is little, acceptance point image data amount increases greatly, can effectively reject background interference simultaneously.

To achieve these goals, the technical solution used in the present invention is: a kind of radiowave underground electromagnetic wave perradiator, comprise radio wave receiver and transmitter, a plurality of receiving coils with Anneta module are set between receiver and transmitter, described Anneta module comprises single-chip microcomputer, A/D conversion and 2.4G wireless communication module, described A/D conversion, 2.4G wireless communication module all is connected on the single-chip microcomputer pin, described receiver comprises single-chip microcomputer, data memory module and 2.4G wireless communication module, data memory module, 2.4G wireless communication module all is connected on the single-chip microcomputer pin.

As preferably, described 2.4G wireless communication module is 2.4G spread spectrum communication module.

Can find out that by above technical scheme the present invention increases greatly for the image data amount of same acceptance point, reduce the accidental error of individual data, improve Explanation Accuracy; The data that record when not launching can effectively be rejected background interference; Greatly reduce receiver operation personnel's working strength, antijamming capability is strong simultaneously, suitable applying.

Description of drawings

In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Fig. 1 is structured flowchart of the present invention.

Embodiment

Further describe the present invention below in conjunction with specific embodiment and accompanying drawing.

As shown in Figure 1, as a kind of embodiment of the present invention, this radiowave underground electromagnetic wave perradiator comprises radio wave receiver and transmitter, a plurality of receiving coils with Anneta module are set between receiver and transmitter, described Anneta module comprises single-chip microcomputer, A/D conversion and 2.4G wireless communication module, the A/D conversion, 2.4G the spread spectrum communication module is all by being connected on the single-chip microcomputer pin at pcd plate upward wiring, described receiver comprises single-chip microcomputer, data memory module and 2.4G spread spectrum communication module, data memory module, 2.4G the spread spectrum communication module is all by being connected on the single-chip microcomputer pin at pcd plate upward wiring.

In actual production process, a plurality of receiving coils are hung on receiving position, owing to carry out data transmission by 2.4G spread spectrum communication module between receiving coil and the receiver, therefore the staff who bears receiver need not again pointwise and carries out data acquisition, only need receiver is fixed in suitable position, just can receive the image data of each receiving coil, not only reduced operation of receiver personnel's working strength, also so that this radiowave underground electromagnetic wave perradiator can be at transmitter during emitting electromagnetic wave, receiving coil still detects environmental background value, the simultaneously setting of a plurality of coils has increased the data volume that gathers greatly, reduce the accidental error of individual data, improve Explanation Accuracy, then, process through the single-chip microcomputer of receiver inside and can effectively reject background interference, the tectonic structure of coal-face has been had more accurate understanding, and simple to operate, easy to use, very suitable spread.

More than technical scheme that the embodiment of the invention is provided be described in detail, used specific case herein principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, all will change on embodiment and range of application, in sum, this description should not be construed as limitation of the present invention.
