Description

Technical Field

[0001] The invention relates to the technical field of substation inspection, and in particular to a simple machine nest micro-weather station for unmanned aerial vehicles in a substation. Background Art

[0002] The power grid promotes the use of substation drones for patrol operations. Due to economic constraints, some substations choose to use simple machine nests with lower prices. Since simple machine nests do not have the function of collecting meteorological data, drone patrol operators rely on security guards in the substation to confirm the on-site meteorological conditions. This operation method has problems such as security guards' inaccurate estimation of wind force levels, some security guards misreporting excessive precipitation to remote operators, and some drones needing additional lighting to take off during night flights, which has a great impact on the efficiency of substation drone patrols. When substations use drones for patrol, how to connect external equipment to the simple machine nest to obtain accurate meteorological information has become an urgent problem to be solved in substation inspections.

[0021] Example 1

[0022] A substation UAV simple machine nest micro weather station, the UAV simple machine nest micro weather station comprising:

[0023] A meteorological collection module, wherein the meteorological collection module comprises a temperature and humidity sensor, a piezoelectric rain gauge and an anemometer.

[0024] A data storage module is connected to the simple machine nest, and the data storage module is connected to the machine patrol platform.

[0025] A serial port module, one end of which is connected to the temperature and humidity sensor, the piezoelectric rain gauge and the anemometer, and the other end of which is connected to the data storage module.

[0026] An illumination module is connected to the simple machine nest.

[0027] The temperature and humidity sensor in the embodiment of the present invention adopts an industrial universal standard interface, which is convenient for connecting to various instruments or systems such as PLC and DCS, and is used to monitor the temperature and humidity state of the simple machine nest. The temperature and humidity sensor uses a high-precision sensor core and related devices to ensure that the product has high reliability and excellent long-term stability.

[0028] In Embodiment 1 of the present invention, the sensor principle in the piezoelectric rain gauge adopts the impact measurement principle, firstly the weight of a single raindrop is measured, and then the continuous rainfall is calculated. The raindrop is affected by the weight of the raindrop and the air resistance during the falling process. When it falls to the ground, the speed is a constant speed V, and the momentum of the raindrop is P=MV=M(Vr+Vw). In the formula, M is the mass of the raindrop, Vr is the vertical raindrop terminal velocity, and Vw is the vertical wind speed. According to the impulse theorem, the momentum of the raindrop will be replaced by the impact force of the sensor element. Under the action of the impact force, the shell of the piezoelectric rain gauge produces mechanical vibration, and the ceramic piezoelectric piece converts the vibration signal into an electrical signal output. Therefore, the corresponding raindrop size and volume are calculated by collecting the peak voltage of the piezoelectric piece output signal. The piezoelectric rain gauge eliminates the influence of debris such as leaves, dust, and insects on the accuracy of the data. It has high sensitivity, high signal-to-noise ratio, simple structure, reliable operation and light weight. It does not require manual on-site cleaning for long-term use, making the rainfall data collection of the simple machine nest more accurate.

[0029] In Example 1 of the present invention, the wind speed sensor in the anemometer is designed with multiple output modes such as RS485, 4-20mA, DC0-5V, etc., which can continuously monitor the wind speed and convert the wind speed into RS485, 4-20mA or DC0-5V signals for transmission to related equipment. The wind speed sensor is made of aluminum alloy material and uses a special mold precision die-casting process. The dimensional tolerance is very small and the surface accuracy is very high. The internal circuits are all protected. The entire sensor has high strength, weather resistance, corrosion resistance and waterproofness. The cable connector has good anti-corrosion and anti-erosion properties, which can ensure the long-term use of the instrument. It can be widely used in greenhouse environmental protection, meteorological stations, ships, docks, heavy machinery, cranes, ports, docks, cable cars, and any place where wind speed needs to be measured.

[0030] In this embodiment 1, the illumination module uses an automatic nighttime illumination lamp, using a pyroelectric infrared sensor and an illumination sensor. The pyroelectric infrared sensor detects a moving human body within a few meters and sends a control signal to turn on the illumination lamp. The illumination sensor detects external light so that the illumination lamp is turned on only in the dark or at night and not during the day. A timer is used to control the illumination time of the bulb within a timing range.

[0031] Example 2

[0032] The UAV simple machine nest micro weather station also includes an electric energy detection module, an electric energy distribution module and a current limiting module. The electric energy detection module is connected to the electric energy module of the simple machine nest, the electric energy distribution module is connected to the electric energy detection module and the UAV respectively, and the current limiting module is connected to the electric energy distribution module.

[0033] Among them, the power detection module detects the power of the simple machine nest and transmits the detection information to the power distribution module and the machine patrol platform. The power distribution module distributes the power of the simple machine nest according to the power consumption of the meteorological collection module and the lighting module. The current limiting module detects the rated power consumption of the meteorological collection module and the lighting module.

[0034] In this embodiment, the power module on the simple machine nest can provide power for the UAV as well as the temperature and humidity sensor, piezoelectric rain gauge, anemometer and lighting module. The temperature and humidity sensor and piezoelectric rain gauge are low power consumption, while the anemometer and lighting module are high power consumption. At the same time, the UAV also has high power consumption compared to the power module on the simple machine nest.

[0035] The power detection module can detect the real-time power of the power module on the simple machine nest. The power distribution module distributes current to the temperature and humidity sensor, piezoelectric rain gauge, anemometer and illumination module according to the power consumption of the temperature and humidity sensor, piezoelectric rain gauge, anemometer and illumination module based on the current distribution circuit.

[0036] Among them, according to the focus of the meteorological observation task and the importance of the sensor, the power supply priority is set for different sensors. For example, in a specific embodiment, when the UAV's demand for wind speed and direction data is more critical, the remote patrol platform can control the power distribution module to prioritize the power on the simple machine nest to the wind speed sensor in the anemometer. When the power supply is tight, it will give priority to meeting its basic working power needs, while automatically reducing the power supply voltage of some other secondary sensors (within the allowable working voltage range) or extending the time to enter sleep mode, to ensure that high-priority, critical meteorological sensors can continue to work stably until the UAV completes the task or returns safely. Among them, when setting the power supply priority of the sensor, the patrol platform dynamically adjusts the power supply strategy for each sensor through the built-in control algorithm, and distributes the power through the power distribution module.

[0037] A current limiting module is provided, which has a precise current control function and can limit the current flowing into the temperature and humidity sensor, piezoelectric rain gauge, anemometer and illumination module according to their respective rated working currents.

[0039] The current limiting module includes a current limiting resistor, and the current limiting resistor is connected to the temperature and humidity sensor, the piezoelectric rain gauge, the anemometer and the illumination module.

[0041] The UAV simple nest micro weather station also includes a solar module, which is connected to the simple nest and provides power for the simple nest. The solar module is combined with the power module of the simple nest micro to provide power for the simple nest micro.

[0042] Example 5

[0043] The data storage module and the drone patrol platform use the MQTT communication protocol for wireless data transmission.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
