Embodiment
In order to illustrate more clearly of technical scheme, embodiment will be used simply to be situated between the present invention below
Continue, it should be apparent that, in describing below is only one embodiment of the present of invention, is come for those of ordinary skill in the art
Say, without having to pay creative labor, other technical schemes can also be obtained according to these embodiments, fallen within
Disclosure of the invention scope.
The transformer substation foundation monitoring system of the present invention, as shown in figure 1, including multiple monitoring points, wireless network and data
Monitoring server.Wherein, each multiple monitoring points set sensing device respectively, for monitoring the underlying parameter of each monitoring point.
Sensing device includes settlement sensor, soil pressure sensor, support column load-bearing monitor sensor and temperature sensor.Wherein,
Settlement sensor is used for the settling data for monitoring monitoring point, and observation stake can be set in monitoring point, is monitored using displacement transducer
The observation stake, so as to obtain the settling data of the datum mark.Soil pressure sensor, support column load-bearing monitor sensor and temperature
Sensor can use pressure sensor well known in the prior art and temperature sensor.
Wireless communication interface is provided with sensing device, the underlying parameter of each monitoring point can be passed by wireless network
Data monitoring service device is sent to, by the operational order that data monitoring service device can be also received by wireless network.It can make
Carried out data transmission with wireless networks such as known cordless communication network such as Zigbee, GPRS or CDMA.
Data monitoring service device carries out data analysis according to the underlying parameter of each monitoring point of reception, according to analysis result
It is controlled for the monitoring parameters of each sensing device.In Basic monitoring, settling data is to influence substation equipment most
Whole factor, and remaining monitoring parameters is to be used for auxiliary monitoring.Therefore, in the monitoring system of the present invention, sensed using sedimentation
Condition of the abnormal data of device as triggering other sensors monitoring.Data monitoring service device controls the sedimentation of each monitoring point to pass
Sensor is monitored using the first monitoring cycle, and the settlement values monitored are sent into data monitoring by wireless network in real time
Server.
Data monitoring service device carries out data analysis to the underlying parameter of each monitoring point of reception, when monitoring single prison
During the settling data exception of measuring point, used for the settlement sensor of the abnormal specific monitoring point of settlement values different from first week
The second round of phase is monitored, and the second round is less than the period 1.Meanwhile data monitoring service device also triggers the monitoring point
Soil pressure sensor, support column load-bearing monitor sensor and temperature sensor make the soil pressure sensor, support column by
Power monitors sensor and temperature sensor is monitored with the respective cycle respectively.Due to soil pressure and support column stress
Amplitude of variation is relatively small, can be by the temperature sensor of the abnormal specific monitoring point of settlement values and second round identical week
Phase is monitored, and soil pressure sensor and support column load-bearing monitor sensor is monitored with the period 3, the period 3
For N times of the second round, N is the integer more than 1.
The settlement of foundation of transformer station is divided into uniform settlement and differential settlement.In general, ground produces uniform settlement, right
Electrical equipment will not cause additional internal stress in itself, will not cause big harm, but should then cause foot to uneven settlement of foundation
It is enough to pay attention to.When differential settlement, which exceedes, bears limit, the cracking of electrical equipment will be produced, tilts or even collapses, jeopardizes peace
Entirely.Therefore, the settlement sensor of the application is not provided with datum mark, when installing settlement sensor, will be set to base by measured value first
Quasi- value, is set to zero；The numerical value of later single measurement is with the difference of a reference value as settlement values；It is each by analyzing
The bulk settling data of monitoring point are analyzed, and determine the abnormal ground of differential settlement.
After data monitoring service device receives the settlement values of all monitoring points, the settlement values of all monitoring points are calculated
Arithmetic mean of instantaneous value and mean square deviation, each monitoring point settlement values and the arithmetic mean of instantaneous value are gone out according to the algorithm mean value calculation
Shift value, when the absolute value of the monitoring point shift value is more than M times of the mean square deviation, M is the integer more than 2,
Judge that the settlement values of the monitoring point are abnormal.
Sedimentation value it is excessive can to react monitoring point sedimentation, it is possible to create risk when more than threshold value.But monitoring
When exceeding threshold value to sedimentation value, harm has been produced.Preferably, data monitoring service device receives the settlement number of all monitoring points
After value, this settlement values of all monitoring points and the difference S of last settlement values are calculated, and calculate the calculation of the difference
Art average value S1 and mean square deviation △ S, so as to calculate the difference of each monitoring point skew S-S1, when S-S1 absolute value is more than
At M times of △ S, judge that the settlement values of the monitoring point are abnormal.It is further preferred that the data monitoring service device receives institute
After having the settlement values of monitoring point, this settlement values for calculating all monitoring points sink with what kth before this monitoring monitored
The difference S of numerical value drops, and the K is the integer more than 2, and calculates the arithmetic mean of instantaneous value S1 and mean square deviation △ S of the difference, from
And the difference skew S-S1 of each monitoring point is calculated, when S-S1 absolute value is more than M times of △ S, judge the monitoring point
Settlement values it is abnormal.
Embodiment described above only expresses the embodiment of the present invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.
