Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
In order to realize real-time monitoring of the operating environment and the operating state of the high-voltage transmission line, a sensor is arranged on the transmission line so as to achieve the detection purpose. And a plurality of types of sensors can be arranged on the transmission line to collect different types of data so as to comprehensively judge whether the transmission line is in a normal state. Optionally, in the embodiment of the present application, each sensor node is disposed at a central portion of the power transmission line wire, and is powered by an independent sensor power supply system, where each sensor node includes a plurality of sensors, and parameters collected by these sensors typically include wire temperature, inclination, current intensity, icing thickness, wind swing, and distance to ground.
Referring to fig. 1, the sensor power supply system includes: the device comprises a spacer, at least one energy taking device, a boosting energy taking device, an energy storage device and a management device. The energy-taking device can be a high-voltage energy-taking device or a solar energy-taking device, and the energy storage device can be an energy storage battery.
Specifically, the high-voltage energy-taking device takes energy through a high-voltage coil, and obtains energy from a wire in a power transmission line through electromagnetic induction. Generally, the high-voltage energy-taking device outputs alternating current, and the alternating current is processed by the power module to become direct current with constant voltage. The energy-taking power of the high-voltage energy-taking device is related to the number of turns of the energy-taking coil, the sectional area of the energy-taking magnetic ring and the coil current, and generally, the energy-taking power is directly related to the current under the condition that the number of turns and the sectional area are determined. When the current is too small, the power output by taking energy is too small, and the voltage output by the management device after processing the power is still not up to the required voltage value; when the current is too large, the energy taking output is saturated, the current is continuously increased, and the output power is not increased any more. The solar energy taking device can obtain electric energy through solar energy, the output of the solar energy taking device is direct-current voltage, and the solar energy taking device can be selectively configured in a sensor energy supply system, so that the solar energy taking device is unnecessary to configure.
As a possible implementation manner, the voltage value obtained based on the energy taking device may be lower than the voltage preset value, so that the boosting energy taking device is set to boost the energy taking device, so that the energy storage device is in a charging state.
The energy storage device is an energy storage battery, the battery is a main energy storage space, and when the energy taking power is high or the sensor does not work, the energy taking surplus power is used for charging the energy storage battery; when the energy is not enough and the sensor still needs to work, the energy storage device can be used for providing the energy for the sensor.
The management device combines the working states of the energy taking device and the energy storage device, monitors the working states, and finally transmits electric energy to the main control and each sub-sensing module of the sensor through the energy taking device, and meanwhile, the main control and each sub-sensing module are connected with the sensor through energy supply signal output to jointly control the action state of the sensor.
Optionally, the sensor energy supply system may further include a super capacitor, and the short-time peak power consumption exists in the working process of the sensor, and the power consumption may be greater than the maximum power that can be supplied by the energy taking module and the battery, and the rapid charging and discharging characteristic of the super capacitor may provide short-time maximum power consumption for the sensor.
The spacer is mainly used for limiting the relative movement between sub-wires and keeping the geometry of split wires under normal operation conditions, thereby meeting the electrical performance, reducing the surface potential gradient, and avoiding the generation of electromagnetic force between wire bundles to cause mutual attraction collision under short circuit conditions. The spacer can be connected with a plurality of wires at intervals, and the energy taking device is connected with different wires to take energy by voltage, so that the energy taking device is connected with the spacer.

The first power is determined according to the specific number of the sensors and the specific working power, and the first power may be the maximum working power corresponding to the plurality of sensors or may be the sum of rated working powers of the plurality of sensors.
S13: the working mode of the sensor is influenced by the energy supply output signal, the corresponding working mode of the sensor is judged according to the type of the energy supply output signal, and the sensor operates in the corresponding working mode according to the judging result.
Specifically, judging the working mode corresponding to the sensor according to the type of the energy supply output signal comprises the following steps: judging whether the output power of the energy taking device is higher than the first power or not according to the energy supply output signal; if not, judging the corresponding preset grade based on the current third voltage data of the energy storage device, and operating the sensor in a corresponding working mode according to the judging result; if yes, the sensor collects and transmits collected data in real time.
As one possible implementation manner, the method for judging the corresponding preset level based on the current second voltage data of the energy storage device and operating the sensor in the corresponding working mode according to the judging result includes: determining the type of the energy supply output signal in the three types of the first energy supply output signal, the second energy supply output signal or the third energy supply output signal according to the current third voltage data of the energy storage device; if the type of the energy supply output signal is a first energy supply output signal, the corresponding preset level is a first preset level, the sensor is in a dormant working mode, and the sensor does not work; if the type of the energy supply output signal is a second energy supply output signal, the corresponding preset level is a second preset level, the sensor is in a heartbeat working mode, and the sensor periodically transmits a heartbeat signal; if the type of the energy supply output signal is a third energy supply output signal, the corresponding preset level is a third preset level, the sensor is in a full-function working mode, and the sensor completes collection of all data.
