Query function: after the completion of sample rate and channel gain are configured, upper computer software can pass through inquiry life at any time
It enables and obtains seismic detector current configuration information and version number information.
Self-checking function: Earthquake occurrence control instrument carries out self-test, and can recycle self-inspection data.Single channel seismic detector is deployed to field
Afterwards, the operations such as parameter setting and system reset, reparation are carried out to problematic seismic detector to solve the problems, such as according to self-detection result, saved
Human-saving material resources improve single station single channel seismic detector high intelligent control degree.
Seismic waveform real-time display function:
Field graphic operation person usually will carry out Quality Identification to earthquake data information, and being shown according to waveform can be promptly and accurately
The quality for understanding collection in worksite data is judged rapidly one between whether abnormal and system the road of the system work of data acquisition
The performance informations such as cause property are realized and carry out effective quality control to earthquake collecting data.Upper computer software is received according to command adapted thereto
By real-time display seismic waveform figure after to data.
Single station seismographic wireless module of single channel has used two kinds of networking models: Ad-Hoc networking model and AP networking mould
Formula.Under AdHoc networking model, upper computer software is as client, and single channel seismic detector is as server.In AP networking model
Under, upper computer software is as server, and seismic detector single channel seismic detector is as client.Login interface upper computer software can select
It selects as client or server log, then transmission of seismic data is by then upper computer software complete independently, i.e. client and clothes
Data interaction between business device.
When being monitored to single single channel seismic detector:
It is mutually communicated using single station single channel host computer and single channel seismic detector 3, the seismographic Wi-Fi module IP of single channel
Address fixed setting is 192.168.1.100, and port 9000 also can according to need and other numerical value are arranged, with specific reference to need
Depending on wanting.Single channel seismic detector connects seismographic wireless signal, IP address as client as server, handheld device
The DHCP function of having wireless device is voluntarily distributed, operation schematic diagram is as shown in Figure 6.
When uniformly being monitored to more seismic detectors,
Using the staff of 1 upper computer software of central server, high-power AP2 is set, what high-power AP here referred to
High-power, long range wireless access point, schematic diagram as shown in figure 5, here high-power AP as a terminal because its
Wireless signal transmission distance is greater than the transmission range of WiFi module, and distance is not too close when actual area exploration, therefore is needed
Want high-power AP as transfer.
The IP address of high-power AP is to be set as 192.168.1.1, port be set as 9000 by server by wired or
The high-power AP of wireless access inquires the single channel seismic detector 3 being currently accessed in AP at this time, the WiFi module in single channel seismic detector
It is connected into high-power AP, the seismic detector not accessed is individually arranged or is corrected, it is made to be connected into high-power AP, seismic detector IP address
And port is voluntarily distributed by the DHCP function of high-power AP, operation schematic diagram is as shown in Figure 5.
Before construction, host computer is the equipment for running upper computer software, sends self-checking command to single channel seismic detector, one by one school
Failure whether there is to seismic detector, the seismic detector of tape jam is corrected or rejected.Host computer is to each seismographic sampling simultaneously
Rate, gain etc. carry out unified inquiry, modification and setting.
When focus operation, host computer is the equipment for running upper computer software, wakes up single channel seismic detector and is acquired work
Industry；Host computer monitors each seismographic state at this time, by sending order for the acquisition data of current seismic instrument to seismic detector
In host computer, whether observation acquisition system work exception and handles accordingly real-time display.
When focus stops working, host computer, which sends instruction, makes single channel seismic detector enter suspend mode, this working method
The seismographic power consumption of single channel is greatly reduced, and without the time of sky acquisition, follow-up data processing workload also drops significantly
It is low.
Two kinds of networking models of the driver of hardware device, when carrying out wireless monitor to single seismic detector, using Ad-
Hoc network carries out networking, when to non-single seismic detector unified monitoring, prison while carrying out more seismic detectors using AP network
Control.Its driver flow chart is as shown in Figure 3.
After module initialization, host computer and single channel seismic detector automatically begin to connect, if so, IP return is waited to refer to
It enables, sends and receive data after opening the port Socket, close Socket port command, terminate, if connectionless, scanning is wireless
Network, after wireless network is added, configuration of IP instruction sends and receives data after opening the port Socket, closes the port Socket
Order terminates.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
