The utility model not only realizes the timely and accurate collection of every pressure parameter of coal miner stope, but also performs timely overall treatment on the collected parameters in order to supply reliable data as reference for safe coal miner production.
Description
Technical field
The utility model relates to a kind of stope working surface of coal mines pressure tester.
Background technology
At present, in coal production and management, need monitor timely and gather the variation of the pillar of stope working surface of coal mines or poppet pressure, axis force of anchor, surrouding rock stress etc., to determine the pillar or the duty of support, the stress state of country rock, the situations such as motion state of overlying rock, for the safety in production in colliery provides corresponding data, carry out smoothly with the safety that guarantees Coal Production.But existing stress collection mostly is to realize that by single mechanical pressure harvester its action need is manually finished, and data acquisition also needs the manual read to get pressure meter to obtain.Mainly there is following defective in said apparatus: 1, needs are manually more, waste time and energy, and acquisition speed is slower, and manual read's error of fetching data is bigger; 2, the artificial back data of gathering need be imported apparatus such as computer again and carry out integrated treatment, and efficient is lower, and the down-hole situation is ever-changing, and this mode is difficult to adapt to present extensive high efficiency downhole production needs; 3, above-mentioned data acquisition unit functional reliability and accuracy are relatively poor.
Summary of the invention
The purpose of this utility model is to provide a kind of stope working surface of coal mines pressure tester at the defective of above-mentioned prior art, this device not only can be realized the every pressure parameter of stope working surface of coal mines is carried out promptly and accurately collection, also can carry out integrated treatment timely, for the safety in production in colliery in time provides reliable data reference to the parameters that collects.
The utility model is achieved through the following technical solutions: a kind of stope working surface of coal mines pressure tester, and it comprises surveys measuring cell and upper PC, connects by wired or wireless data transmission device between measuring cell and upper PC; Above-mentioned measuring cell includes resistance strain type pressure sensor, single-chip microcomputer I, memory I.
Adopt the utility model of this structure, its measuring cell can be provided with a plurality of according to data acquisition position and project, and each measuring cell also can be furnished with a plurality of resistance strain type pressure sensors.The utility model in use, above-mentioned each pressure sensor can be placed on the data acquisition position in the mine, then the pressure sensor pressure data that it can be collected is sent to single-chip microcomputer I, can deposit memory I in after single-chip microcomputer I handles above-mentioned data and also can be transferred to upper PC by wired or wireless data transmission device, upper PC can carry out integrated treatment to the pressure data that each measuring cell transmission comes by special-purpose software, for Coal Production provides reference.Data acquisition of the present utility model and transmission course all realize that by electronic equipment automaticity greatly improves, and has promoted the efficient and the accuracy of data acquisition greatly, and data are in time reliable, the adverse effect of having avoided human error to bring.
The wireless data transmission device of above-mentioned measuring cell and upper PC is an infrared collector, and infrared collector includes single-chip microcomputer II and memory I I, is equipped with the infrared transceiver module that adapts in measuring cell and the infrared collector.The data that the pressure sensor of each measuring cell collects are after measuring cell is handled and stored memory into, can utilize this infrared collector to carry out the infrared data transmission with each measuring cell by above-mentioned infrared transceiver module successively gathers, and storing memory I I into, the transfer of data that infrared then collector collects it is again given upper PC.Upper PC of the present utility model generally can be located at aboveground for ease of working, measuring cell and pressure sensor thereof must be located at the down-hole and need to disperse and be provided with, and the down-hole situation is complicated and changeable, adopt wired mode to carry out comparatively difficulty of transfer of data, above-mentioned infrared collector can be realized the wireless data transmission of measuring cell and upper PC, can further improve the reliability that the utility model uses, be convenient to the setting of measuring cell in the down-hole.
The utility model is described in further detail below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is the structural principle schematic diagram of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model measuring cell;
Fig. 3 is the structural representation of the infrared collector of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model includes the measuring cell 2 of upper PC 1 and suitable number, each measuring cell 2 is by realizing telecommunication with upper PC 1, and each measuring cell 2 all is furnished with a plurality of resistance strain type pressure sensors 3, adopts 2 in the present embodiment; Be provided with single-chip microcomputer I4, memory I 5, programmable clock chip 6, power management chip 8 in the measuring cell 2.
During use, select the pressure sensor 3 and measuring cell 2 of corresponding construction for use according to the difference of measurand, the measuring cell 2 that will be connected with pressure sensor 3 then disperses to be arranged on the relevant position of mine stope, and adopts the mode of RS-485 bus 7 wire communications to be connected by RS-485 bus 7 and upper PC.Programmable clock chip 6 can regularly produce interruption by the time interval of setting, the every interval of single-chip microcomputer I4 certain hour is started, carry out data acquisition program, pressure sensor 3 gather analog signals and after the A/D conversion to the single-chip microcomputer I4 of measuring cell 2, single-chip microcomputer I4 can deposit data in memory I 5 after handling, also can deliver to light-emitting diode display directly shows, after data acquisition is finished, single-chip microcomputer I4 power down, have only programmable clock chip 6 in running order, when programmable clock chip 6 next interrupt cycles (i.e. the data acquisition of setting is at interval) arrival, measuring cell 2 meetings repeating data capture program under the control of single-chip microcomputer I4.
The difference of embodiment 2 and embodiment 1 is that mainly the measuring cell 2 among the embodiment 2 is realized by infrared collector 9 and the wireless data transmission of upper PC, infrared collector 2 includes single-chip microcomputer II10, memory I I11, be respectively equipped with the infrared transceiver module 12 that is used for transfer of data in infrared in addition collector 9 and the measuring cell 2, infrared collector 9 also is furnished with keyboard 13, LCD 14 and carries out the data-interface 15 of transfer of data with upper PC 1, keyboard 13 can be imported various instructions to single-chip microcomputer II10, as parameter setting, data acquisition and data upload etc.Can be provided with the running parameter of measuring cell 2 (as the interval of the machine number of measuring cell, data acquisition time, memory zero clearing etc.) by infrared collector 9.Each measuring cell 2 can carry out transfer of data by infrared transceiver module 12 and infrared collector 9 respectively, and be stored among the memory I I11 after finishing data acquisition, by data-interface 15 transfer of data that infrared collector 9 collects is arrived upper PC 1 then.
The transfer of data that measuring cell 2 of the present utility model and upper PC are 1 both can also can realize by wireless mode by wired mode, and use also can combine wired mode and wireless mode.
