In one embodiment, as shown in fig. 1, a tower status monitoring device is provided, which includes a main control module 100, a data acquisition module 200, a satellite navigation precision single-point positioning module 300, and a power supply module 400. The main control module 100 is connected to the data acquisition module 200, the satellite navigation precise single-point positioning module 300 and the power supply module 400. The data acquisition module 200 monitors state data of the monitored tower, obtains a sampling signal and sends the sampling signal to the main control module 100; the satellite navigation precise point positioning module 300 provides navigation parameters to the main control module 100. The main control module 100 acquires the sampling signal and the navigation parameter, and outputs a tower state monitoring result.
The main control module 100 may be a circuit module including various controllers, control chips and peripheral circuits thereof, and having a logic operation function. The control chip may be a single chip, a DSP (Digital Signal processing) chip, or an FPGA (Field Programmable Gate Array) chip. In one embodiment, the master control module 100 is an Italian semiconductor corporation low power processor. The processor has the advantages of short development period, strong performance, good cost performance, convenience in hardware cutting and the like, and is beneficial to improving the working performance of the tower state monitoring device. The data acquisition module 200 is a hardware module that includes various sensors and can sample status data of the monitored tower. The sensing device can be one or more of a camera, a stress sensor and a tilt sensor. The satellite navigation Precision Point Positioning (PPP) module 300 is a hardware module that includes a satellite receiver and can obtain and provide navigation parameters. For example, the satellite navigation PPP module 300 may be a beidou PPP module. The power module 400 is a device that can output electric energy to the outside, and the power module 400 may include an electromagnetic induction unit that obtains electric energy from the power transmission line based on the electromagnetic induction principle; an electrical energy storage module may also be included. Further, the electric energy storage module can be an energy storage battery pack or a super capacitor.
Specifically, on the one hand, the data acquisition module 200 monitors the state data of the monitored tower to obtain a sampling signal, and sends the sampling signal to the main control module 100, and then the main control module 100 obtains the state information of the monitored tower according to the sampling signal. Further, the state information of the monitored tower includes, but is not limited to, an inclination angle, an icing state, a phoenix dance state, a deformation state and the like. For example, when the data acquisition module 200 includes a camera, the camera sends the acquired picture information to the main control module 100, and the main control module 100 can analyze the inclination angle, the phoenix dance state and the icing state of the monitored tower based on the picture information to obtain the corresponding state information of the monitored tower.
On the other hand, the satellite navigation precision single-point positioning module 300 provides the navigation parameters to the main control module 100, and then the main control module 100 determines the position information of the monitored tower according to the navigation parameters based on the PPP positioning technology. Further, the navigation parameters include satellite orbit and clock error, and non-differential carrier phase observations of the satellite receiver. The main control module 100 may calculate the position information of the tower to be monitored based on the PPP positioning technology according to the satellite orbit and the clock error and the non-differential carrier phase observation data of the satellite receiver. As shown in fig. 2 and 3, after the satellite navigation PPP module 300 is configured, a centimeter-pole positioning accuracy can be obtained.
Finally, the main control module 100 combines the state information and the position information to obtain and output a tower state monitoring result. For example, the main control module 100 may obtain and output a tower state monitoring result including the state information and the position information by combining the state information and the position information; the state information of the monitored tower can be rechecked according to the change condition of the position information to obtain the final state information of the monitored tower, and the tower state monitoring result containing the final state information and the position information is output, so that the reliability of the tower state monitoring result is further improved.

For example, the main control module 100 may output the tower status monitoring result to a terminal or a cloud platform. The terminal includes, but is not limited to, various computers, laptops, smart phones, tablet computers and portable wearable devices. The output mode of the tower state monitoring result can be characters, pictures or curves.

Further, the main control module 100 may compare the corresponding monitoring result with a preset threshold based on the tower state monitoring result, determine whether the state of the monitored tower is normal, and output the warning information when the state of the monitored tower is abnormal.
In addition, a tower applied to a power transmission line is connected with a high-voltage or even ultra-high-voltage transmission power line, a complex electromagnetic environment exists around the power transmission line, and the master control module 100 and each module can generate various different divergent electromagnetic interferences during working, so that consideration such as electromagnetic compatibility design needs to be performed on a tower state monitoring device.

The inclination detection unit is a hardware unit which can convert the physical quantity of the sensor sensitive device to the attitude angle of the earth, namely the included angle (inclination angle) between the sensor sensitive device and the earth gravity into an analog signal or a pulse signal by utilizing the action of the earth gravity. The tilt detection unit may be a solid pendulum, liquid pendulum or gas pendulum tilt detection unit. As shown in Table 1, the test data are different inclination angles of the inclination angle sensor, wherein the standard inclination angle value is the measured value of the standard equipment of the measurement institute. As can be seen from table 1, the tilt sensor can achieve a measurement accuracy of 0.01 ° within a certain range. As shown in table 2, the data is measured for a plurality of times at the same tilt angle. As can be seen from table 2, the angle set in the test was 5 °, the average of the actual multiple measurements was 4.99857 °, and the standard deviation was 0.003 °.
