Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The remote monitoring system and the remote monitoring method for the substation base settlement according to the embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a block diagram of a remote monitoring system of substation base settlement according to one embodiment of the present invention.
As shown in fig. 1, the system includes a plurality of monitoring stations 110, a reference station 120, a server 130, and a remote monitoring terminal 140. The server 130 is in wireless communication with the reference station 120 and each monitoring station 110, respectively, and the server 130 is in communication with the remote monitoring terminal 140.
The reference station 120 and each monitoring station 110 respectively obtain respective positioning data and send the respective positioning data to the server 130; the server 130 determines the three-dimensional coordinate value of each monitoring station 110 according to the positioning data of the reference station 120 and the positioning data of each monitoring station 110, and sends the three-dimensional coordinate value of each monitoring station 110 to the remote monitoring terminal 140; the remote monitoring terminal 140 determines the centroid coordinate value of the base according to the three-dimensional coordinate value of each monitoring station 110, and determines whether the base is settled according to the centroid coordinate value.
Thus, by providing multiple monitoring stations 110 on the base; the reference station 120 and the monitoring station 110 acquire positioning data and send the positioning data to the server 130; the server 130 obtains the three-dimensional coordinate value of each monitoring station 110 according to the positioning data of the reference station 120 and the monitoring stations 110, and the server 130 sends the three-dimensional coordinate value of each monitoring station 110 to the remote monitoring terminal 140; the remote monitoring terminal 140 determines the centroid coordinate value of the base according to the three-dimensional coordinate value of each monitoring station 110, and determines whether the base is settled according to the centroid coordinate value, so that the remote monitoring terminal 140 can monitor whether the base is settled through the change of the centroid coordinate value, and the base of the transformer substation is more accurately remotely monitored.
Reference station 120, monitoring station 110, server 130, and remote monitoring terminal 140 are described in detail below.
In the embodiment of the present invention, the reference station 120 may use a GNSS (Global Navigation Satellite System) receiver, and an antenna of the GNSS receiver may use a 3D choke coil. The reference station 120 can receive satellite positioning data transmitted by a satellite in real time through an antenna, where the satellite positioning data at least includes carrier phase data, pseudo-range observation values, coordinate data, and the like. The reference station 120 may increase the data accuracy of the obtained satellite positioning data from a centimeter level to a millimeter level, and may further increase the accuracy of the three-dimensional coordinate values obtained by subsequent calculation.
Since the reference station 120 needs to be located at a position where coordinates are known and the position is stable, the reference station 120 can be located at a position where the position in the substation is stable and the signal can cover the whole monitoring area (i.e. the whole substation base).
The monitoring station 110 in the embodiment of the present invention may also use a GNSS receiver, and similarly, the antenna of the GNSS receiver may use a 3D choke coil. Each monitoring station 110 is capable of observing satellite navigation signals for satellite positioning data. The satellite positioning data at least includes carrier phase data, pseudorange observations, and coordinate data of the monitoring station 110.
At least 3 monitoring stations 110 need to be arranged on the substation base, so that a geometric plane can be formed, and mass center coordinate values of the base can be determined subsequently. In some embodiments, 4 monitoring stations 110 may be disposed on the base, and disposed corresponding to four corners of the base. Specifically, if the base is rectangular, the monitoring stations 110 may be respectively disposed at four corners of the base, and after the monitoring stations 110 are connected together as much as possible, the centroid of the formed geometric plane can coincide with the centroid of the base plane. Therefore, the position change conditions of the 4 positions of the base can be monitored.
After the reference station 120 and each monitoring station 110 obtain respective positioning data (i.e., carrier phase data, pseudo-range observation values, coordinate data of the reference station 120, and coordinate data of the monitoring stations 110), the reference station 120 and each monitoring station 110 transmit the respective positioning data to the server 130, and the server 130 processes the positioning data to obtain a three-dimensional coordinate value of each monitoring station 110.
In some embodiments, the server 130 wirelessly communicates with the reference station 120 and each monitoring station 110 through a respective wireless gateway 150 to obtain the positioning data of the reference station 120 and the positioning data of each monitoring station 110, respectively. Specifically, the reference station 120 and each monitoring station 110 are respectively provided with a wireless gateway 150; after the reference station 120 and each monitoring station 110 obtain respective positioning data, the reference station 120 and each monitoring station 110 send the obtained positioning data to the wireless gateway 150; wireless gateway 150 retransmits the location data to server 130 via internet 160. Thereby, communication between the reference station 120, the monitoring station 110 and the server 130 is achieved. In addition, it should be noted that the Internet 160 may be an Internet network.
In some embodiments, the reference station 120 and the monitoring station 110 may further adopt a GNSS receiver integrating the receiver and the wireless gateway 150, and implement a function of internet of things by inserting a Subscriber Identity Module (SIM) card into the GNSS receiver. Thereby facilitating communication between the reference station 120 and the monitoring station 110 and the server 130.
The server 130 is any server 130 capable of running a position solution algorithm and an error correction algorithm. The server 130 operates the position calculation algorithm and the error correction algorithm, and obtains the three-dimensional coordinate value of each monitoring station 110 by using the positioning data sent by the reference station 120 and each monitoring station 110 as the operation parameters of the position calculation algorithm and the error correction algorithm.
In some embodiments, the server 130 performs Real-Time solution of the spatial coordinates of the positioning data of the reference station 120 and the positioning data of each monitoring station 110 by using an RTK (Real Time Kinematic) position solution algorithm, so as to obtain the three-dimensional coordinate value of each monitoring station 110.
The RTK position resolving algorithm eliminates the pseudo-range deviation of 110 carrier waves of the monitoring station, 110 clock error of the monitoring station and satellite clock error by constructing dual-difference observed values between stations and satellites, greatly weakens the influence of satellite orbit error, atmospheric error and the like on the whole-cycle ambiguity search, enables the whole-cycle ambiguity to be rapidly fixed, and obtains real-time high-precision three-dimensional coordinate values of each monitoring station 110. The specific solution process of the RTK position solution algorithm may refer to an existing RTK position solution process, and will not be described herein.
In addition, in the process of resolving the three-dimensional coordinate values, the resolving result may be affected by various types of deviations that are not eliminated in the observed values, the geometric configuration of the satellite, and the fixation error of the whole-cycle ambiguity, so that the positioning accuracy may not reach the preset standard. In some embodiments, a coarse difference elimination method may be used to eliminate the deviation, so as to improve the precision of the obtained three-dimensional coordinate values.
Therefore, the server 130 can realize real-time calculation and correction of the three-dimensional coordinate values of each monitoring station 110 by running the RTK position calculation algorithm, thereby obtaining high-precision three-dimensional coordinate values.
After the server 130 obtains the three-dimensional coordinate value of each monitoring station 110, the remote monitoring terminal 140 obtains the three-dimensional coordinate value of each monitoring station 110 from the server 130, determines the centroid coordinate value of the base according to the three-dimensional coordinate value of each monitoring station 110, and then judges whether the base is settled according to the centroid coordinate value.
In some embodiments, the server 130 provides an access interface for the remote monitoring terminal 140 to retrieve the three-dimensional coordinate values of each monitoring station 110 by running the B/S architecture base settlement monitoring software.
First, it should be noted that the remote monitoring terminal 140 includes but is not limited to: mobile terminals such as mobile phones, notebook computers, PDAs (personal digital assistants), PADs (tablet computers), in-vehicle terminals (e.g., in-vehicle navigation terminals), and the like, and fixed terminals such as digital TVs, desktop computers, and the like. The remote monitoring terminal 140 is only an example, and should not bring any limitation to the function and the scope of the application of the embodiment of the present invention.
Specifically, the remote monitoring terminal 140 can run B/S architecture base settlement monitoring software, and the B/S architecture base settlement monitoring software can access an interface of the server 130 through the internet 160, retrieve the three-dimensional coordinate value of each monitoring station 110 from the server 130, calculate the centroid coordinate value according to the three-dimensional coordinate value of each monitoring station 110, and realize operations such as dynamic monitoring of the substation base through monitoring the centroid coordinate value.
In addition, the remote monitoring terminal 140 may call the current three-dimensional coordinate value of each monitoring station 110 from the server 130 at a preset interval, and calculate the centroid coordinate value of the primary base to determine whether the substation base is settled. It should be noted that the preset period may be set according to an actually required monitoring frequency, and is not limited herein.
In some embodiments, the remote monitoring terminal 140 determines the centroid coordinate value by:
wherein, X P 、Y P And Z P Is the centroid coordinate value, n is the number of the monitoring stations 110, i is the identification information of the monitoring stations 110, X i 、Y i And Z i Is the three-dimensional coordinate value of the monitoring station 110.
It should be noted that each monitoring station 110 may be provided with identification information, so that the monitoring station 110 can be identified by the identification information. The identification information may be a numbered index of the monitoring station 110, such as, "monitoring station 1#", "monitoring station 2#", and the like.
The remote monitoring terminal 140 calls the current three-dimensional coordinate value of each monitoring station 110 from the server 130 every time a period passes, and calculates the centroid coordinate value of the current base plane once through the above centroid coordinate value calculation formula; the remote monitoring terminal 140 may determine whether the base is settled by comparing the centroid coordinate value of the current base with a preset initial value. It should be noted that the initial centroid coordinate value of the substation base may be stored, and the initial centroid coordinate value is used as a preset initial value.
As an example, after the substation base is built, by obtaining the three-dimensional coordinate values of each monitoring station 110, the initial centroid coordinate value of the base is (32.5, 15.3, 18.7), and the initial centroid coordinate value is stored. After the transformer substation is used for a long time, the three-dimensional coordinate value of each current monitoring station 110 is obtained, the centroid coordinate value of the current base is (32.6, 15.1 and 13.7), and the base can be known to be settled by comparing the centroid coordinate value of the current base with the initial centroid coordinate value.
In addition, after the remote monitoring terminal 140 obtains the centroid coordinate value of the current base, the centroid coordinate value may be stored in the memory of the remote monitoring terminal 140, and the centroid coordinate value is used as historical data, so as to analyze the base settlement condition in the following step.
To improve the accuracy of substation base settlement monitoring, in some embodiments, the remote monitoring terminal 140 is specifically configured to: and calculating a centroid coordinate estimation value of the base according to the centroid coordinate value, and judging whether the base is settled according to the centroid coordinate estimation value and a preset initial value.
Specifically, after the remote monitoring terminal 140 obtains the current centroid coordinate value of the base, the centroid coordinate estimated value can be obtained according to the centroid coordinate value of the current period of the base and the centroid coordinate value of the previous period of the base, so as to reduce the deviation caused by the operation error of the remote monitoring terminal 140.
In some embodiments, the remote monitoring terminal 140 calculates the centroid coordinate estimate by:
wherein, the first and the second end of the pipe are connected with each other,
and
is the estimated value of the centroid coordinate of the base at the time t, P is a filter adjustment factor, X P 、Y P And Z P Are the centroid coordinate values.
It should be noted that the filtering adjustment factor may be preset in the remote monitoring terminal 140 by an operator, and the operator may set or adjust the filtering adjustment factor according to actual requirements, where the value interval of P is [0,1], and the value of the filtering adjustment factor is not specifically limited here.
Therefore, the remote monitoring terminal 140 can obtain the current centroid coordinate estimated value of the base through the calculation formula of the centroid coordinate estimated value, and judge whether the substation base is settled according to the centroid coordinate estimated value.
In some embodiments, the remote monitoring terminal 140 is further specifically configured to: and determining a coordinate difference value of the centroid coordinate estimation value and a preset initial value, judging whether the coordinate difference value exceeds a preset threshold value, and determining that the base is settled when the coordinate difference value exceeds the preset threshold value.
Specifically, after the centroid coordinate estimation value of the base in the current period is obtained through calculation, the remote monitoring terminal 140 may determine a coordinate difference value according to a pre-stored preset initial value and the centroid coordinate estimation value of the current period, and then determine whether the base is settled according to the coordinate difference value. In some embodiments, the remote monitoring terminal 140 may determine the coordinate difference by:
wherein the content of the first and second substances,
and
is an estimate of the centroid coordinate of the t-period pedestal, X P (0)、Y P (0) And Z P (0) Is a preset initial value, T X 、T Y And T Z Is a preset threshold. Note that T is X 、T Y And T Z Can be manually set according to the monitoring requirement, and T X 、T Y And T Z The setting may be the same preset threshold value or different preset threshold values.
As an example, T X 、T Y And T Z Are set to 0.2m, preset initial values of (20.36, 12.54, 33.23), and the accuracy of the coordinates is in millimeters. If the estimated value of the centroid coordinate of the base in the current period is (20.21, 12.43, 33.06), obtaining the coordinate difference value through the calculation formula of the coordinate difference value
Thereby enabling a determination that the substation foundation has settled.
In some embodiments, the remote monitoring terminal 140 is provided with a display, and the display displays a staff interface, which can display the centroid coordinate estimation value of the base, the three-dimensional coordinate value of each monitoring station 110, and the coordinate difference value between the centroid coordinate estimation value and the preset initial value, and the staff can view the data through the remote monitoring terminal 140.
In some embodiments, the remote monitoring terminal 140 is further provided with an alarm module, and when the remote monitoring terminal 140 monitors that a coordinate difference between the centroid coordinate estimation value of the base in the current period and the preset initial value exceeds a preset threshold (i.e., the base is settled), the controller of the remote monitoring terminal 140 may control the alarm module to alarm to prompt a worker that the base is settled.
In addition, the alarm module can be a speaker, and when the base subsides, the controller of the remote monitoring terminal 140 can control the speaker to give an alarm to prompt the staff that the base subsides. The alarm module may also be the display of the remote monitoring terminal 140, when the base is settled, the controller of the remote monitoring terminal 140 may control the display to display an alarm prompt box, and alarm prompt information is displayed in the alarm prompt box, where the alarm prompt information may be in the form of "base settlement", "base settlement alarm", and the like.
Thus, the respective positioning data is transmitted to the server 130 via the reference station 120 and each monitoring station 110 via the internet 160; obtaining a three-dimensional coordinate value of each monitoring station 110 by the server 130 according to the positioning data; the three-dimensional coordinate value of each monitoring station 110 in the current period is called from the server 130 through the remote monitoring terminal 140, the centroid coordinate value of the base is obtained through calculation according to the three-dimensional coordinate value of each monitoring station 110, the centroid coordinate estimation value of the current base is obtained according to the centroid coordinate value, and whether the base is settled or not is judged according to the centroid coordinate estimation value. Because the barycenter coordinate estimated value can represent the situation of change of the whole position of the base, whether the transformer substation base sinks or not can be monitored more accurately. Secondly, the staff can obtain the change situation of the whole position of the base by checking the data of the remote monitoring terminal 140, so that the remote dynamic monitoring of the base is realized, and the operation of the staff for dynamically monitoring the base is simplified.
