Embodiment
In order to be illustrated more clearly in technical scheme of the present invention, below use embodiment is introduced simply to the present invention, apparently, in the following describes is only one embodiment of the present of invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other technical scheme can also be obtained according to these embodiments, also belong to open scope of the present invention.
Transformer substation foundation monitoring system of the present invention, as shown in Figure 1, comprises multiple monitoring point, movable sensor, wireless network, data monitoring service device and data storage server.Wherein, each multiple monitoring point arranges fixing sensing device respectively, for monitoring the underlying parameter of each monitoring point.Fixing sensing device comprises settlement sensor, soil pressure sensor, support column load-bearing monitor sensor and temperature sensor.Wherein, settlement sensor, for monitoring the settling data of monitoring point, can arrange observation stake in monitoring point, uses displacement transducer to monitor this observation stake, thus obtains the settling data of this reference point.Soil pressure sensor, support column load-bearing monitor sensor and temperature sensor can use pressure transducer well known in the prior art and temperature sensor.
Movable sensor is the sensor that each monitoring point shares, and it can move between each monitoring point according to instruction, thus reduces the cost arranging sensor in each monitoring point.The measurement parameter of this movable sensor is measurable parameter for not needing setting to be arranged on below basis, such as, measure the horizontal angle sensor etc. that level angle uses.
Be provided with wireless communication interface in fixing sensing device and movable sensor, the underlying parameter of each monitoring point can be sent to data monitoring service device by wireless network, by also can be received the operational order of data monitoring service device by wireless network.Known cordless communication network such as the wireless networks such as Zigbee, GPRS or CDMA can be used to carry out data transmission.
Data monitoring service device carries out data analysis according to the underlying parameter of each monitoring point received, and controls according to the monitoring parameter of analysis result for each sensing device.In Basic monitoring, settling data is the final factor affecting substation equipment, and remaining monitoring parameter is for auxiliary monitoring.Therefore, in monitoring system of the present invention eventually, use the abnormal data of settlement sensor as the condition triggering other Sensor monitorings.The settlement sensor that data monitoring service device controls each monitoring point uses the first monitoring periods monitoring, and in real time the settlement values monitored is sent to data monitoring service device by wireless network.
The underlying parameter of data monitoring service device to each monitoring point received carries out data analysis, when the settling data monitoring single monitoring point is abnormal, settlement sensor for the specific monitoring point of settlement values exception uses to be different from monitors the second round of period 1, and this second round is less than the period 1.Meanwhile, data monitoring service device triggers described movable sensor and moves to this specific monitoring point and monitor for this specific monitoring point.
Preferably, transformer substation foundation monitoring system of the present invention also comprises data-storage system, it stores the positional information of each monitoring point, when the Monitoring Data of multiple monitoring point is abnormal, data monitoring server reads the positional information of the plurality of monitoring point in data-storage system, according to the mobile route of this positional information setting movable sensor, this mobile route is made to be the shortest in all possible paths.
The settlement of foundation of transformer station is divided into uniform settling and non-uniform settling.In general, ground produces uniform settling, can not cause additional internal stress, can not cause large harm, but then should cause enough attention to uneven settlement of foundation to electrical equipment itself.When non-uniform settling exceed bear limit time, just can produce the cracking of electrical equipment, tilt even collapse, jeopardize safety.Therefore, the settlement sensor of the application does not arrange reference point, when installing settlement sensor, will be decided to be reference value by measured value first, and being set to zero; The numerical value of later single measurement and the difference of this reference value are as settlement values; By analyzing the bulk settling data analysis of each monitoring point, determine the ground of non-uniform settling exception.
After data monitoring service device receives the settlement values of all monitoring points, calculate arithmetic mean and the mean square deviation of the settlement values of all monitoring points, the shift value of each monitoring point settlement values and described arithmetic mean is gone out according to this algorithm mean value calculation, when the absolute value of described monitoring point shift value is greater than the M times of described mean square deviation, M be greater than 2 integer, judge that the settlement values of this monitoring point is abnormal.
Sedimentation value, when exceeding threshold value, can react this monitoring point sedimentation excessively, may produce risk.But, when monitoring sedimentation value and exceeding threshold value, harm can be produced.Preferably, after data monitoring service device receives the settlement values of all monitoring points, calculate this settlement values of all monitoring points and the difference S of last settlement values, and calculate arithmetic mean S1 and the mean square deviation △ S of this difference, thus calculate the difference skew S-S1 of each monitoring point, when the absolute value of S-S1 is greater than the M times of △ S, judge that the settlement values of this monitoring point is abnormal.Preferred further, after described data monitoring service device data monitoring service device receives the settlement values of all monitoring points, calculate this settlement values of all monitoring points and this monitor before the difference S of settlement values that monitors for the K time, described K be greater than 2 integer, and calculate arithmetic mean S1 and the mean square deviation △ S of this difference, thus calculate the difference skew S-S1 of each monitoring point, when the absolute value of S-S1 is greater than the M times of △ S, judge that the settlement values of this monitoring point is abnormal.
The above embodiment only have expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
