Abstract
The invention discloses a mud-rock flow monitoring method. A main machine is arranged in a safe place near a mud-rock flow hazardous body, and smart sensors are arranged at various monitored sites of the mud-rock flow hazardous body. When earthquake sound vibration signals received by the smart sensors exceed the preset upper trigger threshold value, the earthquake sound vibration signals are collected, displayed and stored. The invention also discloses a mud-rock flow monitoring, analyzing and early-warning device. The mud-rock flow monitoring, analyzing and early-warning device can record data generated by a mud-rock flow so as to conveniently analyze the mechanism of the mud-rock flow. Because the collected signals are digitalized at a front end, the main machine receives digital signals, and the problem that analog signals are easy to be mixed with noises in a long-distance collection and transmission process is effectively solved. Moreover, through triggering by a preset upper trigger threshold value and ending by a preset lower trigger threshold value, a certain quantity of data is collected and stored, and invalid data is prevented from occupying a limited space.

2, when adjusting the parameter of sensor, be not connected if will adjust the sensor of parameter with the rubble flow monitoring analyzer, open the power switch of rubble flow monitoring analyzer earlier, receive the cable end of sensor on the rubble flow monitoring analyzer this moment again; Be connected on the rubble flow monitoring analyzer if will adjust the sensor of parameter, earlier the cable end of sensor to be pulled up from the rubble flow monitoring analyzer, as above operated again.
3, when the inside enlargement factor of adjusting sensor or trigger gate limit value, if send order failure ([] Input command error) or the communication error code is arranged, operation more preferably starts anew behind the power-off restarting.
Step s602 lays main frame and intellectualized sensor.Main frame is laid near the safe part mud-stone flow disaster body, intellectualized sensor is laid in mud-stone flow disaster body measured point everywhere, described intellectualized sensor is embedded in the described measured point soil body below 10 centimetres.The scene has the 220V alternating current then can be connected in the supply socket, does not have alternating current then to be connected on storage battery so that electric power to be provided, if the on-the-spot storage battery inconvenience of changing then can connect solar panels so that charging on storage battery by the 12V interface.
Step s603 receives the earthquake sounds vibration signal of described measured point by described intellectualized sensor.
Step s604 judges whether described earthquake sounds vibration signal surpasses the described trigger gate limit value of going up, if then change step s605, otherwise change step s603;
Step s605 sends alerting signal, gathers, shows and store described earthquake sounds vibration signal, and described earthquake sounds vibration signal comprises amplitude and frequency.
The display interface of earthquake sounds vibration signal as shown in figure 10.Under the display interface of earthquake sounds vibration signal, can reduce the triggering waveform display screen number of respective sensor by " 1 " key; Can increase the triggering waveform display screen number of respective sensor by " 2 " key; Can reduce the outside enlargement factor of respective sensor by " 4 " key; Can increase the outside enlargement factor of respective sensor by " 5 " key.
In the display interface of earthquake sounds vibration signal, m is a seeker, AAAA is last trigger gate limit value, BBBB is following trigger gate limit value, and EE is for triggering waveform display screen number, and FF is the outside enlargement factor of probe, TX is respectively and represented the 1st passage, the 2nd passage, the 3rd passage at 1,2,3 o'clock respectively, when CC DD is No SD, represent not insert the SD card, represent that when CC DD is SD ok the SD card initialization is correct, when CC DD is SD XX, represent the incorrect or not format of SD card format.
Storage format during storage earthquake sounds vibration signal is as shown in table 2.

Step s606 judges whether the earthquake sounds vibration signal that receives is lower than described trigger gate limit value down, if then finish collection, demonstration and the storage of described earthquake sounds vibration signal.
Center signal value in the present embodiment under the side head static state is 0x7FF, and the scope of signal is 0～0x0FFF, when signal greater than last trigger gate in limited time, instrument just begins acquired signal, gather 512 data points after, display waveform on lcd screen.After the triggering, acquiescence shows 5 screen waveforms (5*48 data point), and the screen number of demonstration is adjustable.Under the waveform display screen, reduce to show length by 1 key, increase demonstration length by 2 keys, scope is 1～11 screen.
The present invention can write down the data of rubble flow generation so that the mechanism of rubble flow is analyzed, because the signal of gathering has been carried out digitized processing at front end, what main frame received is digital signal, efficiently solves simulating signal is easily infiltrated noise in the remote capture transmission course problem; And the present invention triggers by default last trigger gate limit value and following trigger gate limit value finishes, and to the collection and the storage of some data, has avoided invalid data to take limited space.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
