Description

Node instrument monitoring method and system and electronic equipment Technical Field The invention belongs to the technical field of resource exploration, and particularly relates to a method and a system for a node type seismic exploration instrument and corresponding electronic equipment. Background Currently, as the onshore oil and gas exploration of China expands to the fields of complex structures, deep ultra-deep layers and unconventional fields, higher requirements are put on the precision and efficiency of the exploration technology. The seismic exploration method is an important petroleum and natural gas exploration means, and the seismic instrument is key equipment for implementing the seismic exploration method. Types of seismic instruments commonly used in the industry include wired seismic instruments (hereinafter referred to as wired instruments) and nodal seismic instruments (hereinafter referred to as nodal instruments). The wired instrument is limited by the problems of complex terrain adaptability, high power consumption, failure detection efficiency and the like, so that the requirements of modern high-density and high-efficiency seismic exploration are difficult to meet. The current node type seismic prospecting instrument gradually replaces a wired instrument to become the main stream of oil and gas resource exploration, and the adaptability and the operating efficiency of complex terrains such as mountain areas, deserts and the like are obviously improved by virtue of the constraint advantages of wireless cables. The node instrument has many advantages, but a plurality of technical short plates still exist in field exploration operation, namely firstly, the working state of the node (including key parameters such as electric quantity, storage capacity and clock synchronization) cannot be monitored in real time, so that faults are difficult to discover in time, secondly, the seismic data acquisition quality lacks a field evaluation means, the quality control can be carried out only after the node is recovered, if the abnormal signal is discovered, the reworking and the recovery are often needed, and in addition, the node faults are difficult to locate and the construction efficiency is seriously influenced in complex terrain or large-scale operation. These disadvantages not only increase the operational risk and management difficulty, but are more likely to potentially impact the integrity and reliability of the survey data. In order to solve the problems, in the prior art, manufacturers in the industry push out node instruments based on real-time transmission of commercial 4G/5G communication networks, and real-time check of node states and seismic data is realized. Because of the limitation of the prior art, the node instrument monitoring also has the main problems that the real-time scheme relying on the 4G/5G public network is limited by field signal coverage, meanwhile, the node power consumption is increased rapidly under the real-time transmission mode to cause short endurance, the deployment cost is high, the existing autonomous networking technology is easy to generate the problems of unstable links and coverage faults when large-scale nodes are deployed due to the lack of topological design adapting to the exploration scene, the states of node electric quantity, clock synchronization, position change and the like cannot be mastered in real time, the quality control can be realized after the seismic data is recovered, the abnormal situation needs to be reworked and recovered, and the fault positioning efficiency is extremely low. It can be known that the prior art has the difficulty that high power consumption, high cost and application convenience cannot be avoided, and the requirement of large-scale efficient exploration operation cannot be well met. Therefore, development of a method, a system and corresponding electronic equipment for monitoring a node instrument is needed, the problem of 'single point inefficiency' of the existing node instrument monitoring is broken through, and a low-cost and high-reliability solution is provided for ultra-large-scale seismic exploration under complex surface conditions, so that deep application of a resource exploration technology is promoted. Disclosure of Invention The invention provides a node instrument monitoring method, which is designed to monitor network grouping architecture in real time, and provides oil and gas exploration acquisition equipment with stable and reliable work for ultra-large scale seismic exploration operation of complex surface areas such as deserts, mountain areas and the like, so that real-time feedback monitoring of node working state data and acquisition seismic data is realized, and exploration data quality is ensured. The node instrument monitoring system provided by the invention is used for being matched with the node instrument monitoring method provided by the invention, and overcomes the specific t
