The invention provides a source drive control device and a source drive control method for an explosive source. The device comprises a source drive controller and a protocol converter, wherein the source drive controller is connected with a decoder of a to-be-excited shot point; the protocol converter is connected with a main machine of a seismic apparatus, and data exchange and time synchronization are performed between the protocol converter and the source drive controller; the source drive controller comprises a GPS (global positioning system) module, a first information input module, a first CDMA (code division multiple access) communication module and a microcontroller module; the protocol converter comprises a second CDMA communication module, a serial communication module and a second microcontroller module. According to the technical scheme, the construction efficiency of seismic exploration of the explosive source is increased, the seismic data quality is improved, the labor strength of working personnel is obviously reduced, and the source drive technology for the explosive source is applied by conveniently utilizing the existing equipment.

Description

technical field [0001] The invention relates to the technical field of exploration and development of petroleum, natural gas and coal resources, in particular to an explosive seismic source drive control device and control method. Background technique [0002] In conventional seismic exploration, after arriving at the position of the shot point to be excited, the staff generally manually finds the stake number of the shot point to be excited and reports it to the seismic instrument. The operator of the seismic instrument finds the corresponding acquisition arrangement from the excitation point list according to the stake number, then activates the arrangement and starts the seismic source to start acquisition. [0003] Source-driven control technology refers to a control method in which the excitation source control device transmits the shot point coordinates to the seismic instrument and enables the seismic instrument to automatically select the shot point in seismic explor...

Problems solved by technology

In addition, the existing conventional explosive source control devices do not have the source driving function. Even the excitation source controller with the source driving function is not universal due to the technical limitations of the manufacturer. At the same time, the coordinate information transmitted by the radio station is also easily interfered.

[0005] Therefore, the technical problem to be solved by the present invention is that the conventional explosive seismic source control device has no source-driven function, and the source-driven construction technology cannot be applied in seismic exploration construction. The existing excitation source controller uses wireless stations for data exchange and synchronization and is easily disturbed
