Abstract
The utility model discloses a wireless transmission control system for down-the-hole rock drilling. The wireless transmission control system for the down-the-hole rock drilling comprises a hole bottom sensor, a signal converter, a ground upper computer and a bluetooth transceiver, wherein the bluetooth transceiver is installed on a drill stem which is connected with a drill bit; the hole bottom sensor is connected with the signal converter which is connected with the bluetooth transceiver, the bluetooth transceiver sends wireless signals through an internal signal projector and achieves wireless communication with the ground upper computer; drilling tool working condition information is sent to the signal converter through the hole bottom sensor, the signal converter conducts signal conversion on the information and then sends the information to the bluetooth transceiver, and then the bluetooth transceiver sends the information to the ground upper computer in a wireless communication mode. The bluetooth transceiver is used for conducting wireless communication on a hole bottom signal, a bluetooth conversion base station is reasonably arranged according to the effective distance of bluetooth transmission, difficulties of wire arrangement of the wireless transmission are avoided, reliability of signal transmission is greatly improved, and the wireless transmission control system is suitable for the special working environment of the down-the-hole rock drilling.
Description
Technical field
The utility model relates to a kind of radio transmission control system, particularly a kind of radio transmission control system for down-the-hole drilling.
Background technology
At present when down-the-hole drilling, in time understand the work information of hole subdrilling tool for convenience, usually adopt near drilling tool placement sensor that the rock drilling parameter is gathered, then the signal that collects is reached the ground host computer in the mode of wire transmission and carry out analyzing and processing.Wire transmission is mainly transmitted signal step by step by the mode of arranging holding wire in drilling rod, and than higher, the drilling rod contact position is easy to wear to the Structural Design Requirement of drilling rod for this transmission means, and the signal transmission reliability is low.
The utility model content
The purpose of this utility model provides a kind of stabilizing effective radio transmission control system for down-the-hole drilling.
This radio transmission control system for down-the-hole drilling that the utility model provides, comprise sensor at the bottom of the hole, signal adapter, ground host computer and be installed in drilling rod that drill bit is connected on bluetooth transceiver therein; Sensor is connected with signal adapter at the bottom of the hole, and signal adapter is connected with bluetooth transceiver therein, and bluetooth transceiver therein sends wireless signal by the internal signal transmitter, carries out radio communication with the ground host computer; Sensor reaches signal adapter with the drilling tool work information at the bottom of the hole, and signal adapter carries out this information to reach bluetooth transceiver therein after the signal conversion, and bluetooth transceiver therein reaches the ground host computer with it with communication again.
Described bluetooth transceiver therein comprises signal receiver, baseband controller and signal projector.
Some described drilling rod and some common drilling rods that bluetooth transceiver therein has been installed join end to end, connect a described drilling rod that bluetooth transceiver therein is installed every two common drilling rods, form some bluetooth transceiver thereins ordered arrangement from bottom to top, carry out wireless transmission of signal each other between adjacent two bluetooth transceiver thereins, finally reach the ground host computer, realize the radio relay communication transmission to rock drilling work information at the bottom of the hole.
Signal carried out wireless transmission at the bottom of the utility model utilized bluetooth transceiver therein to the hole, coverage reasonable Arrangement bluetooth conversion base station according to Bluetooth transmission, avoid the difficulty of wire transmission wiring, significantly improved the reliability of signal transmission, be applicable to particular job environment of down-the-hole drilling.In addition, bluetooth belongs to the communication frequency band that share in the whole world, and anti-interference strong, versatility is good, and is cheap, system maintenance easy.
Description of drawings
Fig. 1 is a kind of specific embodiment of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprise sensor at the bottom of the hole, signal adapter, ground host computer and be installed in drilling rod that drill bit is connected on bluetooth transceiver therein.Bluetooth transceiver therein comprises signal receiver, baseband controller and signal projector.
The coverage of Bluetooth signal transmission at present is usually between 10cm ~ 10m, the length of rock drilling drilling rod is generally between 1m ~ 1.5m, consider the particular surroundings that Bluetooth signal transmits in drilling rod, in order to guarantee intensity and the continuity of signal transmission, every bluetooth transceiver therein of 3 ~ 5m location arrangements, namely connect a drilling rod that bluetooth transceiver therein is installed every two common drilling rods, some drilling rod and some common drilling rods that bluetooth transceiver therein has been installed join end to end, form some bluetooth transceiver thereins ordered arrangement from bottom to top, thus sensor signal is received and transmits with the relay transmission manner, finally arrive the signal analysis and processing system on ground.
Sensor carries out the A/D conversion with the drilling tool real-time working condition information that monitors by signal adapter at the bottom of being installed in the hole of subdrilling head position, hole, and be sent to the signal receiver of bluetooth transceiver therein 1, this signal receiver reaches it its baseband controller again, signal after this controller will be handled again reaches its signal projector, this transmitter is sent to next adjacent bluetooth transceiver therein 2 with signal in the mode of radio communication again, bluetooth transceiver therein 2 reaches next adjacent bluetooth transceiver therein 3 more in the same way, until the bluetooth transceiver therein n that transfers near the ground host computer, relay transmission successively finally transfers to the ground host computer thus.
In each bluetooth transceiver therein, when receiving wireless signal, signal receiver is sent to baseband controller with the wireless signal that receives after processing such as synthesizer filtering, amplification, demodulation; When sending wireless signal, by baseband controller data to be sent are reached synthesizer, carried out sending it to by signal projector after the carrier modulation treatment signal receiver of next bluetooth transceiver therein again by synthesizer.
