Abstract

The invention relates to a working state wireless monitoring method for a cableless digital storage seismograph, and the method comprises the following steps: introducing a Wi-Fi (wireless fidelity) wireless communication module based on a cableless seismograph acquisition station; connecting the seismograph acquisition station with a seismograph host, notebook computer or PDA (Personal Digital Assistant) for state monitoring through a wireless networking technology; and establishing a special communication protocol for carrying out working state wireless monitoring on the cableless seismograph. In the method, a three-stage network structure composed of a central station, a wireless routing station and the acquisition station is used, wherein the seismograph host is connected with the central station, the central station is connected with the wireless routing station through a wireless link, and the wireless routing station widens the coverage area of the link; and a master-slave mode is used by the communication protocol, so that the cableless seismograph covering a long distance and a wide range can be conveniently and reliably subjected to networking. Thus, the method can be used for solving the defect that the working state of the existing cableless seismograph can not be monitored in real time, realizing the wireless real-time monitoring of the cableless storage seismograph, greatly improving the field construction efficiency and saving the exploration cost.

Description

Technical field: [0001] The invention relates to a wireless monitoring method for the working state of a seismograph, in particular to a wireless monitoring method for the working state of a cableless digital storage seismograph. Background technique: [0002] Seismic prospecting is an important means of surveying oil and natural gas resources before drilling, and has been widely used in coal field and engineering geological exploration, regional geological research and crustal research. Conventional seismic exploration uses cables to connect all systems and realize information acquisition operations. This method has disadvantages such as bulky system, difficult handling, low construction efficiency, high labor costs, and limited acquisition functions and accuracy. When the number of traces reaches a certain number, this This disadvantage is particularly prominent. [0003] For this reason, non-cable digital storage seismographs have been launched one after another at home ...
