Referring to the schematic structural diagram of the remote explosion system of the gun shown in fig. 4, the implementation process of the device will be described below with reference to specific implementation steps.
The explosion machines 001, 002, … … and 100 can be located at any position near the explosive wellhead where each explosion machine needs to detonate on the premise of ensuring a certain safety distance from the explosive wellhead. The encoder, the capacity expansion end and the main machine box of the earthquake instrument are all placed in the main machine box of the earthquake instrument, and the main machine box of the earthquake instrument can be additionally arranged on a special vehicle of the earthquake instrument or a computer room. The explosion machine and the encoder carry out data transmission in a wireless communication mode, and the distance between the encoder and the explosion machine can reach more than ten kilometers, so that the wireless communication mode meeting the communication distance requirement is a radio station transmission mode. The coder is connected with the capacity expansion end through the first connecting end, and the capacity expansion end receives communication data sent by the coder in real time and sends the data to the coder in real time. The capacity expansion end is connected with the seismic instrument main box body through the second connecting end, and the capacity expansion end sends communication data to the seismic instrument main box body in real time and receives data from the seismic instrument main box body in real time.
The remote explosion system needs to work normally and all three parameters which must meet the contract of the remote explosion system are matched. The first explosive machine 001, the second explosive machine 002 to the first explosive machine 100 all contain three parameters a, B and C, and since the above three parameters are not identical, all of the parameters a, B and C are given the same identification numbers as the associated explosive machine on the drawing, for example, see fig. 4, for the explosive machine 001, the parameters thereof include the parameters a001, B001 and C001, for the explosive machine 002, the parameters thereof include the parameters a002, B002 and C002, and for the explosive machine 100, the parameters thereof include the parameters a100, B100 and C100. Because the device supports the explosive motor-pumped well gun source driving mode to carry out well gun construction, the following construction mode takes the well gun source driving mode as an example.
After all preparations are completed, the explosion machine operators complete the geographical information acquisition of the current well gun position by utilizing the self GPS module of the held explosion machine and send the geographical information acquisition to the encoder in a wireless communication mode in real time. The encoder carries out real-time compression encoding on the parameters A, B and C, the geographic information, the rest data related to the explosion machine and some data parameters of the encoder, which are received from the explosion machine, so as to form a new data stream, and the new data stream is transmitted to the capacity expansion end through the first connecting end in a wired communication mode. The capacity expansion end analyzes the data stream, removes useless information, stores the geographic information transmitted by the encoder in real time, reconstructs a new data stream and transmits the new data stream to the main box body of the earthquake instrument through the second connecting end.
And the seismic instrument host box body analyzes the new data flow and displays a reconstructed new explosion number on a seismic instrument host software display interface. After checking the parameters, the operator clicks the host software of the earthquake instrument to operate and send out an ignition command. And transmitting the data stream formed by the ignition instruction to the capacity expansion end through the second connecting end. And the capacity expansion end transmits the data stream to the encoder through the second connection end when waiting for a whole second according to the GPS clock, stores the whole second GPS time at the capacity expansion end and transmits the time to the main box body of the earthquake instrument. The encoder is sent to an explosion machine to be detonated in a wireless communication mode, the detonator and the explosive are detonated, and meanwhile, the earthquake instrument starts recording. The display screen of the expansion end can display some real-time parameters and information.
Referring to the external interface connection schematic diagram of the expansion end shown in fig. 2, the expansion end is connected to the first data interface 201, the second data interface 202, the power interface 203, and the input/output interface 204.
The power interface provides a 10-15V direct current power supply for the expansion end through an external power transformer, and a waterproof and dustproof protective sleeve is covered outside the power interface. The first data interface is connected with the encoder through a first connecting end and is responsible for receiving data from the encoder and transmitting data of the capacity expansion end, and the first data interface is also responsible for providing power supply for the encoder. The second data interface is connected with the seismic instrument main box body through a second connecting end and is responsible for sending communication data to the seismic instrument main box body and receiving the communication data sent by the seismic instrument main box body. The input/output interface is responsible for firing the internal program of the expansion end, and sends the internal storage data of the expansion end and some expansion functions to the external equipment. The input/output interface is additionally provided with a waterproof and dustproof protective cover when not in use.
