All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a capacity expansion device and method for a well cannon remote explosion system and the well cannon remote explosion system, which can overcome the defects of the existing technology and method of an explosive machine, adopts a new capacity expansion method for the well cannon remote explosion system, and achieves the purpose of improving the production efficiency of a well cannon construction mode in the geophysical exploration industry by designing a simple and convenient installation, stable performance and reliable quality, additionally arranging a small adapter device in a wired remote-measurement seismic instrument bin on the premise of not changing any software and hardware structure of the existing explosive machine and only using a single encoder to support more explosive machines.
In order to facilitate understanding of the embodiment, first, a detailed description is given to the capacity expansion device of the well-cannon remote detonation system disclosed in the embodiment of the present invention.

The first connection end is used for receiving the data of the explosive machine sent by the encoder and sending the data of the explosive machine to the capacity expansion end; the capacity expansion end is used for receiving the data of the explosive machine, generating capacity expansion data according to the data of the explosive machine and transmitting the capacity expansion data to the seismic instrument host by utilizing the second connecting end; the seismic instrument host is used for receiving the capacity expansion data, generating an ignition instruction and sending the ignition instruction to the capacity expansion end through the second connecting end; generating an ignition instruction according to the capacity expansion data; the expansion end is further used for receiving an ignition instruction, generating an explosion instruction according to the ignition instruction, and sending the explosion instruction to the encoder through the first connecting end so that the encoder controls the target explosive machine to explode according to the explosion instruction.
In an embodiment of the present invention, the detonator data includes appointment parameters for the detonator, geographic information, and remaining data relating to the detonator. The appointed parameters can be preset, and are mainly a starting code, a queue number and an ID number, wherein the ID number is used for distinguishing different explosive machines.
And the capacity expansion end generates capacity expansion data according to the data of the explosive machine, wherein the capacity expansion data is obtained by dynamically changing the appointed parameters in the data of the explosive machine. For example, the agreed parameters in the original data of the explosive machine comprise a starting code 1, a queue number 1 and ID numbers 1-10 corresponding to the queue number 1; starting code 1, queue number 2 and ID numbers 1-10 corresponding to queue number 2; the starting code 1, the queue number 3 and the ID numbers 1-10 corresponding to the queue number 3 are modified by the capacity expansion end, and the obtained capacity expansion data are the starting code 1, the queue number 1 and the 10 ID numbers corresponding to the queue number 1; starting code 1, queue number 1 and ID number 11-20 corresponding to queue number 1; starting code 1, queue number 1 and ID number 21-30 corresponding to queue number 1; that is, the expansion end may modify the ID in the queue number other than queue number 1 to the ID number of the sequence number following the existing ID number of queue number 1.

For example, if the default parameters preset in the encoder are the start code 1 and the queue number 2, the explosive machine with the default parameters of the start code 1 and the queue number 1 cannot be detonated. The detonation of the detonator is only enabled if the encoder is in agreement with the agreed parameters of the detonator. The explosive machine transmits the three parameters into the encoder in a real-time wireless transmission mode, the encoder transmits the three parameters into the expansion end through the first connecting end, the expansion end transmits the reconstructed data into the seismic instrument through the second connecting end according to the system requirements of the line remote sensing seismic instrument through analysis and reconstruction in real time, and therefore the number of the explosive machines supported by the existing seismic instrument is met, and the purpose of improving the production efficiency of the well-cannon construction mode in the geophysical exploration industry is achieved.

Referring to the schematic structural diagram of the well cannon remote detonation system shown in fig. 4, the implementation process of the device is described below by combining specific implementation steps.
The explosive device 001, the explosive device 002, … … and the explosive device 100 can be located at any position near the well head of the explosive device to be detonated by each explosive device, on the premise of ensuring a certain safety distance from the well head of the explosive device. The encoder, the expansion end and the seismic instrument host box body are all arranged in a seismic instrument host instrument cabin, and the instrument cabin can be additionally arranged on a special vehicle for seismic instruments or can be a computer room. The data transmission is carried out between the explosive machine and the encoder in a wireless communication mode, and the distance between the encoder and the explosive machine can reach more than ten kilometers, so that the wireless communication mode required by the communication distance is a radio station transmission mode. The encoder is connected with the capacity expansion end through the first connecting end, and the capacity expansion end receives communication data sent by the encoder in real time and sends the data to the encoder in real time. The capacity expansion end is connected with the seismic instrument host box body through the second connecting end, and the capacity expansion end sends communication data to the seismic instrument host box body in real time and receives data from the seismic instrument host box body in real time.
The remote explosion system needs to work normally and must meet the requirement that all three parameters appointed by the remote explosion system are matched. The first 001, second 002 to hundredth 100 exploders contain three parameters a, B and C, since these three parameters are not exactly the same, all following each parameter a, B and C with the same reference numerals as the associated exploder on the figure, see for example fig. 4, for the first 001, the parameters include a parameter a001, a parameter B001 and a parameter C001, for the second 002, the parameters include a parameter a002, a parameter B002 and a parameter C002, and for the first 100, the parameters include a parameter a100, a parameter B100 and a parameter 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 the explosive operators are ready, the geographic information of the current well and cannon position is acquired by using the own GPS module of the explosive, and the geographic information is sent to the encoder in real time in a wireless communication mode. The encoder performs real-time compression encoding on the A, B and C parameters, the geographic information, the rest data related to the explosive machine and some data parameters of the encoder, which are received from the explosive machine, to form a new data stream, and the new data stream is transmitted to the expansion end through the first connection end in a wired communication mode. And the capacity expansion end analyzes the data stream, removes useless information, stores the geographic information transmitted by the encoder in real time, reconstructs the geographic information into a new data stream, and transmits the new data stream to the seismic instrument host box body through the second connecting end.
And the seismic instrument host box body analyzes the new data stream and displays the reconstructed new explosive number on a seismic instrument host software display interface. And clicking the software of the seismic instrument host to operate and send an ignition instruction after the checking parameters are confirmed to be correct by the seismic instrument operator. And the data stream formed by the ignition instruction is transmitted to the expansion end through the second connecting end. And the capacity expansion end waits for the whole second according to the GPS clock, forwards the data flow to the encoder through the second connecting end, stores the whole second of GPS time at the same time, and forwards the time to the seismic instrument host box. The encoder is sent to an explosive machine needing to be detonated in a wireless communication mode, the detonator and the explosive are detonated, and meanwhile the seismic instrument starts to record. The display screen of the expansion end can display some real-time parameters and information.
Referring to the schematic diagram of the external interface connection 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 first data interface is connected with the encoder through a first connecting end, is responsible for receiving data from the encoder and sending data of the capacity expansion end, and is also responsible for providing power supply for the encoder. The second data interface is connected with the seismic instrument main machine box body through the second connecting end and is responsible for sending communication data to the seismic instrument main machine box body and receiving the communication data sent by the seismic instrument main machine box body. The input and output interface is responsible for burning the internal program of the capacity expansion end and sending the internal storage data of the capacity expansion end and some expansion functions to the external equipment. When the input/output interface is not used, a waterproof and dustproof protective cover is additionally arranged.
