Description
Technical Field
The invention belongs to the technical field of structural radio equipment, and particularly relates to a router based on a field broadband seismograph observation station and a data transmission method.
Background
In the twenty-first century, the seismology research based on the dense seismic array observation has made a series of significant progress under the drive of the observation technology and the theoretical progress. The broadband flowing seismic array consists of a plurality of seismic stations with certain observation execution periods (generally 1-2 years); the wide-band fixed earthquake table net consists of a plurality of fixed tables which are permanently arranged at fixed positions for a long time. The field wide-band seismograph observation station is generally composed of a seismometer, a data acquisition unit (including a GPS time service system), a power supply system and a possible data transmission system.
At present, the domestic wide-band earthquake observation basically adopts the mainstream advanced seismograph observation equipment in the world, and all the equipment has the internet communication capability. The prior art scheme of the field earthquake observation station for remote data transmission is that a 3G/4G industrial wireless router which is universal in the market is loaded at a seismograph data acquisition end, and a mobile wireless network signal is obtained by inserting a mobile phone communication card into the router or a wired network is connected for data transmission. However, the field conditions for earthquake observation are complicated and changeable, and the observation needs to avoid the influence of human activities as much as possible, so the distribution position of the earthquake station is generally remote. Flowing seismic stations typically do not have a wired network for field observation, and mobile network signals are often not continuous enough or even free of signals (fixed seismic stations are typically more well established for decades of observation). The commercial router belongs to general equipment, and when a network signal is unstable and the interruption is abnormal and serious, the commercial router is automatically restarted after being dialed for many times (for example, 5 times) unsuccessfully, so that a data packet currently being transmitted is lost. After the router is restarted, a new packet is sent that was received from the seismograph. In addition, the memory card on which the seismometer records data may lose the data. In field observation, precious raw data may be lost due to seismograph identification data memory card failure caused by external observation condition change, seismograph internal failure, etc., data card failure identified by data reading equipment (computer), etc. In addition, the data storage card of the seismometer has limited capacity, for example, the data storage card of a Reftek130 type earthquake collector is a CF card, and the size is usually 4G/8G. The length of time that the data memory card can record data is also related to the data sampling rate, etc. When the seismograph station is not patrolled in the field and the data card is replaced in time after a certain period of time, the data card can be circularly written in the data according to default setting, and the data recorded before is overwritten. In this way, a complete data record is not obtained. These problems are not solved in the existing offline observation mode (periodic station patrol inspection), and even if a commercial router is used for real-time data transmission, the problems are influenced by the fact that many stations do not have mobile signals or abnormal data transmission is caused by signal strength problems. There is still much room for solution and improvement of these problems.

As shown in fig. 9, in an optional embodiment, the router 100 may further include: a data transmission module 130 connected to the processor 150 for transmitting the data stored in the data storage module 120.

Acquiring a state: when the seismometer 500 is operating to normally acquire and record data, the acquisition state should be indicated as acquiring (e.g., "start on"). However, due to human error or instrumentation, the seismometer 500 may be in a state of stopping acquisition. When the router monitors the situation, the router generates a first regulating instruction and sends the first regulating instruction to the seismograph 500, and the first regulating instruction enables the seismograph 500 to start collecting.
Clock state: the time precision is very important for the seismic data belonging to the time series signals, the time of the seismograph data is based on a GPS time service system, and the GPS signals are easily influenced by factors such as weather. When the clock state is good, such as the GPS state indicates "Status OK", the data clock difference is generally less than ± 10us (e.g., ± 1 us). When the router monitors that the GPS locking is abnormal, the clock difference is larger than a set threshold (for example, the clock difference is larger than 1ms), the router generates a first regulating and controlling instruction and sends the first regulating and controlling instruction to the seismometer 500, and the first regulating and controlling instruction sets a GPS searching mode of the seismometer 500 from a periodic mode (once every 1 hour, in a power saving mode) to a continuous mode so as to realize real-time quick locking; and when the monitoring is normal, regulating and controlling the GPS searching mode of the seismograph back to the periodic mode.
Seismometer centroid position: the three-component centroid position of the seismometer is reflected on the three-component voltage of the seismometer. During the working process of the seismometer, the position of the mass center can drift. The seismometer voltage is abnormal, and the seismic data acquisition is influenced. For example, when the seismometer centroid on a component is completely unregulated for "fluttering", the data recorded for that component is a straight line. When it is monitored that the voltage of a component of the seismometer exceeds a threshold value (for example, 1v for CMG 3ESP/3T seismometer in england), the router generates a first control instruction and sends the first control instruction to the seismometer 500, and the first control instruction enables the seismometer 500 to adjust the center of mass to be centered.
The working voltage is that the field seismological observation station is provided with a power supply system part, is usually connected with a storage battery, and charges the storage battery through a charger by mains supply (alternating current) or a solar panel. The working voltage of the seismograph is generally stabilized above 12.5 v. When the router monitors that the voltage is abnormal, corresponding intelligent power management can be carried out on the seismograph according to the preset condition, so that the seismograph can record data for a longer time. For example, when it is found that the working voltage of the seismograph continuously increases/increases at night (the charger is in a charging state) and continuously decreases in the daytime (the seismograph station is continuously in a power consumption only state), the router generates a first regulation and control instruction and sends the first regulation and control instruction to the seismograph 500, the first regulation and control instruction enables the router to close power consumption of real-time data transmission and the like in the daytime but does not affect the normal data acquisition function of the seismograph 500, and the corresponding function is restarted at regular time.
