On the other hand, the invention also provides a vibration anti-overturn monitoring method for the vehicle-mounted precision optical equipment, and the vibration anti-overturn monitoring system is particularly adopted.
As shown in fig. 4, the vibration anti-rollover monitoring method provided in one embodiment of the present invention includes the steps of:
s1, preparing to carry out transition transportation on the precision optical equipment;
s2, starting to detect the precision optical equipment in the transportation process;
s3, judging whether the vibration sensor exceeds the limit, if so, stopping the vehicle for checking, and if not, executing a step S4;
if the real-time acceleration value detected by the vibration sensor exceeds a set acceleration threshold value, judging that the vibration sensor is out of limit;
s4, judging whether the tension values of the tension sensors are consistent, if so, carrying normally, and if not, stopping and checking;
and if the difference between the real-time tension mean value and the initial tension mean value of the tension sensor is within a set range, judging that the tension values of the tension sensors are consistent.
In a specific implementation mode, taking a transportation vehicle-mounted optical theodolite as an example, before transportation, an acceleration threshold is set according to the equipment condition of the vehicle-mounted optical theodolite, and the vibration sensor 2 is mainly used for reading the acceleration value of the vehicle-mounted optical theodolite in real time in the transportation process; the set alarm threshold may be specifically classified into different alarm thresholds according to grades, specifically, the acceleration threshold may include an acceleration threshold corresponding to a general alarm state, that is, a general alarm threshold, and an acceleration threshold corresponding to a serious alarm state, that is, a serious alarm threshold, where the general alarm threshold is lower than the serious alarm threshold; for example, setting a general alarm threshold value to be that the instantaneous state can not exceed 10m/s2(ii) a Setting a severe alarm threshold value of 20m/s2(ii) a When the vibration sensor 2 detects the acceleration reading of 11m/s in real time2When the alarm is triggered, a general alarm state is considered to be triggered, and the general alarm state can be prompted through an alarm indicator lamp or a monitoring host computer and a current log is recorded; when the vibration sensor 2 detects the acceleration reading of 22m/s in real time2When the alarm is in a serious alarm state, the alarm or the like or the monitoring host prompts the serious alarm state and records the current log; in this embodiment, a triggering of a severe alarm condition, in which the auxiliary fastening parts of the optical theodolite may be loose and a parking check should be performed, is regarded as a vibration sensor overrun.
The acceleration threshold value, namely the initial threshold value, which is correspondingly set by the vibration sensor 2 can be obtained by a comprehensive pre-road test; for example: the same type of equipment host computer, if 20m/s appears in the road surface test2The peak value is subjected to precision verification after transportation to cause precision loss, and then the precision loss is considered to be 20m/s2A serious alarm state; when transporting other different precision optical equipment, different general alarm thresholds and serious alarm thresholds can be set correspondingly. In a preferred embodiment of the invention, the acceleration threshold corresponding to the general alarm state is one half of the input power corresponding to the acceleration threshold corresponding to the serious alarm state; on one hand, the general alarm state and easy triggering caused by the over-low threshold value can be avoided, and the function is further disabled; on the other hand, the precision loss of the equipment caused by long-time small-amplitude vibration due to vibration accumulation caused by overhigh threshold value can be prevented.
In the specific embodiment, taking the optical theodolite on board a transport vehicle as an example, the output unit of the tension sensor 3 is newton (N); because the center of gravity of the optical theodolite equipment is higher, four anti-overturning cables 4 are generally required to be used for fixing in a transportation state; the tension sensor 3 is arranged in the middle of each anti-turnover cable 4 and used for detecting the real-time stress state of the anti-turnover cable 4.
Judging whether the tension values of the tension sensors are consistent, wherein the inconsistent tension values mainly mean inconsistent with the difference values of the initial states, namely the difference between the real-time tension mean value and the initial tension mean value of the tension sensor 3 is within a set range, judging that the tension values of the tension sensors are consistent, and normally transporting; if the difference between the real-time tension mean value and the initial tension mean value of the tension sensor 3 is out of the set range, the tension value of the tension sensor is judged to be inconsistent, and the parking inspection is required. For example: before the vehicle-mounted optical theodolite is transported, the initial readings of the four tension sensors 3 are respectively 200N, 205N, 198N and 211N, the average value is 203.5N, the 20% variation range is set to be normal, when the average value reading output by the tension sensor 3 changes within [203.5 +/-40.7 ] N, the normal transportation state is judged, when the instantaneous reading of any one tension sensor 3 of the four tension sensors exceeds the area, for example, the reading is 100N or 400N, the tension values are judged to be inconsistent, the state can be caused by the looseness of one anti-turning cable 4, an alarm is triggered, and the parking inspection state is required.
In a preferred embodiment, the speed sensor is used for recording log use, the output of the speed sensor is the current vehicle speed, and when the alarm is triggered when the vibration sensor exceeds the limit or the tension value of the tension sensor is inconsistent, the current vehicle speed, the vibration recording value and the video monitoring signal are recorded together; specifically, each sensor in the sensor module and the monitoring host carry out signal communication through an IEEE802.15.4/ZigBee scheme.
In a specific implementation mode, in the whole transportation process, according to a general alarm threshold and a serious alarm threshold which are correspondingly set by the vibration sensor 2, the vehicle-mounted precision optical equipment vibration anti-overturn monitoring system can correspondingly set two alarm modes, namely slight vibration early warning and serious vibration alarming; when the acceleration value detected by the vibration sensor 2 in real time reaches a general alarm threshold value, the system does not record corresponding to slight vibration early warning; when the acceleration value detected by the vibration sensor 2 in real time reaches a serious alarm threshold value, corresponding to a serious vibration alarm, the system needs to record relevant data. Preferably, under the condition that a serious vibration alarm is not achieved, the vibration anti-overturn monitoring system can record data in a sampling mode at the frequency of 1Hz, and the vibration sensor 2 always collects data at the frequency of 200 Hz. When a serious vibration alarm condition is reached and/or an alarm condition of the tension sensor is reached, the vibration anti-overturn monitoring system can record recording data of all aspects corresponding to 5 seconds before and after an alarm point, specifically comprises the recording of the vibration sensor 2, the recording of the tension sensor 3, the recording of the speed sensor to the current vehicle speed, the recording of a video signal acquisition device to a real-time state picture of the whole precision optical equipment 1 and the like, current time node information is given through a file name, and the vibration and stress condition in the transportation process of the transition verification equipment can be used by analyzing a state log corresponding to the recording data subsequently.
According to the vibration anti-overturn monitoring system for the vehicle-mounted precision optical equipment, the vibration, the pulling force and the video monitoring are integrated, so that the function of monitoring the health of the precision optical equipment in a transportation state is realized. Detecting the rigidity condition of the current equipment transportation tool through a vibration sensor, and reminding a driver through a monitoring host if equipment looseness and anti-turnover function failure caused by road surface conditions occur; detecting the tension state of the anti-overturning cable in the current equipment transportation process through a tension sensor, and determining whether the equipment is in a balanced and stable state; meanwhile, the video monitoring is further adopted, so that the condition that transport personnel can know the equipment state in the transport process in real time in a non-stop state is guaranteed, the transition transportation of the precision optical equipment is realized conveniently and quickly, and the links of manual getting-off operation in the transport process are obviously reduced.
