Description

Technical Field

[0001] This invention relates to the field of data acquisition technology, specifically a photovoltaic intelligent data acquisition and monitoring method. Background Technology

[0002] When large-area photovoltaic equipment is in operation, it is necessary to monitor its data to facilitate daily management and maintenance. In addition to collecting and detecting electrical data, the data detection items of photovoltaic equipment also include the detection of surface temperature, light intensity, cleanliness, etc. Usually, a photovoltaic panel requires at least one set of detection sensors. However, if the sensor fails, it will lead to inaccurate data collection. If it is not detected in time, it will affect the long-term monitoring data. Setting up two sets of sensors for simultaneous detection is more expensive. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a photovoltaic intelligent data acquisition and monitoring method, which solves the problems that sensor failure can lead to inaccurate data acquisition, and failure to detect it in time can affect long-term monitoring data, while setting up two sets of sensors for synchronous detection is costly.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic intelligent data acquisition and monitoring method, specifically comprising the following steps:

[0005] S1. Install the data acquisition module: First, install the data acquisition module above the photovoltaic module using the moving mechanism, ensuring that there are no obstructions between the data acquisition module and the photovoltaic panel;

[0006] S2. Connecting the equipment: Connect the power cord of the acquisition module and the moving mechanism to the monitoring equipment, power it through the monitoring equipment, and connect the monitoring equipment to the output line of the photovoltaic panel to monitor the current, voltage and power values ​​output by the photovoltaic panel; you can choose to use a solar panel as a power source to reduce dependence on external power.

[0007] S3. Set monitoring parameters: Set the running time of the acquisition module, determine that it is nighttime when the light intensity is lower than the set value, stop running, and set the running time pattern of the moving mechanism;

[0008] S4. Start Monitoring: Start the monitoring equipment and acquisition module. The monitoring equipment starts collecting and monitoring the current, voltage and power data of the photovoltaic module output current. The acquisition module collects the light intensity, photovoltaic panel surface temperature and cleanliness data and summarizes them to the monitoring equipment for recording. At the same time, when the running time of the moving mechanism is reached, the moving mechanism drives the two acquisition modules in the same group to switch positions and exchange acquisition objects to continue collecting data.

[0009] S5. Anomaly Analysis: Analyzes the error in data collected by the two acquisition modules corresponding to the same photovoltaic panel before and after the acquisition module position is switched. When the error exceeds the set value, an early warning is issued to prompt staff to come for maintenance.

[0010] Preferably, the data acquisition components of the acquisition module include a light intensity sensor, a vision sensor, and an infrared temperature sensor.

[0011] Preferably, the moving mechanism includes a track plate mounted above two adjacent photovoltaic panels. Two sets of mounting bases slide relative to each other on the track plate, and the acquisition module is mounted on the mounting bases. The track plate has two symmetrically arranged guide grooves in the front and rear rows to guide the sliding trajectory of the two sets of mounting bases respectively. The middle part of the two rows of guide grooves forms an ellipse, so that when the two sets of mounting bases come together, they gradually shift their positions forward and backward. The bottom of the track plate is provided with a drive component to drive the two sets of mounting bases to move relative to each other.

[0012] Preferably, the mounting base includes a base plate and a bent sliding rod fixedly connected to one side of its bottom. The bent sliding rod passes through the guide groove and bends to hook onto the track plate. U-shaped rods are fixedly connected to both the left and right sides of the bottom of the base plate, and a sleeve is provided in the middle of the U-shaped rod to reduce the resistance of the mounting base sliding.

[0013] Preferably, the drive assembly includes an annular pull rope, the front and rear sections of which are connected to bent slide rods of different mounting bases via elastic bands.

[0014] Preferably, both ends of the annular pull rope are fitted with drive wheels, and one drive wheel is driven by a servo motor. The inner side of the drive wheel is provided with a rubber sleeve to increase the friction with the annular pull rope. Guide wheels for guiding the annular pull rope are provided on one side of the drive wheel and on both the front and rear sides of the annular pull rope.

[0015] Preferably, the top two ends of the track slab are provided with baffles, and buffer strips are attached to the opposite side of the baffles on both sides.

[0016] Preferably, the track plate, drive wheel, servo motor and guide wheel are all mounted on the base plate and then mounted on the bottom surface or photovoltaic module via the base plate.

[0017] Beneficial effects

[0018] This invention provides a photovoltaic intelligent data acquisition and monitoring method. Compared with the prior art, it has the following advantages:

[0019] 1. This photovoltaic intelligent data acquisition and monitoring method uses acquisition modules arranged in pairs on adjacent photovoltaic panels to collect surface data from each panel. By using a moving mechanism to install the acquisition modules, the two acquisition modules in a pair can be periodically switched, allowing for switching of the data collection target. This means that different acquisition modules can be used to detect the same photovoltaic panel sequentially, enabling cross-referencing. If one acquisition module malfunctions, it can be identified promptly, thus avoiding the problem of inaccurate data collection due to undetected equipment failures and effectively improving data accuracy.

[0020] 2. In this photovoltaic intelligent data acquisition and monitoring method, the mounting base slides through the substrate. By using the reverse movement of the front and rear sections when the annular pull rope of the drive component rotates, the two sets of mounting bases can be moved relative to each other. Moreover, one annular pull rope can connect multiple pairs of mounting bases on all photovoltaic panels to move together. That is, multiple sets of moving mechanisms can share one drive component, which has better synchronization and is easier to control. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention discloses a photovoltaic intelligent data acquisition and monitoring method, which specifically includes the following steps:

[0030] S1. Install the data acquisition module 1: First, install the data acquisition module 1 above the photovoltaic module using the moving mechanism, ensuring that there are no obstructions between the data acquisition module 1 and the photovoltaic panel;

[0031] S2. Connecting the equipment: Connect the power cord of the acquisition module 1 and the moving mechanism to the monitoring equipment, power the equipment, and connect the monitoring equipment to the output line of the photovoltaic panel to monitor the current, voltage, and power values ​​output by the photovoltaic panel; you can choose to use a solar panel as the power source to reduce dependence on external power.

[0032] S3. Set monitoring parameters: Set the running time of the acquisition module 1, determine that it is nighttime when the light intensity is lower than the set value, stop running, and set the running time pattern of the moving mechanism;

[0033] S4. Start monitoring: Start the monitoring equipment and acquisition module 1. The monitoring equipment starts to collect and monitor the current, voltage and power data of the photovoltaic module output current. The acquisition module 1 collects the light intensity, photovoltaic panel surface temperature and cleanliness data and summarizes them to the monitoring equipment record. At the same time, when the running time of the moving mechanism is reached, the moving mechanism drives the two acquisition modules 1 in the same group to switch positions and exchange the acquisition objects to continue collecting data.

[0034] S5. Anomaly Analysis: Analyze the error in data collected by the two acquisition modules 1 corresponding to the same photovoltaic panel before and after the position of acquisition module 1 is switched. When the error exceeds the set value, an early warning will be issued to prompt the staff to come for maintenance.

[0035] The data acquisition components of acquisition module 1 include a light intensity sensor, a vision sensor, and an infrared temperature sensor.

[0036] This invention also discloses a moving mechanism and provides the following two technical solutions:

[0037] Figure 1-4 The first embodiment is shown: the moving mechanism includes a track plate 2 mounted above two adjacent photovoltaic panels. Two sets of mounting bases 3 slide relative to each other on the track plate 2, and the acquisition module 1 is mounted on the mounting base 3. The track plate 2 has two rows of guide grooves 4 symmetrically arranged to guide the sliding trajectory of the two sets of mounting bases 3 respectively. The middle part of the two rows of guide grooves 4 forms an ellipse, so that the two sets of mounting bases 3 gradually shift their positions forward and backward when they come together. The bottom of the track plate 2 is provided with a drive assembly 5 for driving the two sets of mounting bases 3 to move relative to each other. Both ends of the top of the track plate 2 are provided with baffles 6, and the opposite side of the baffles 6 is attached with a buffer strip 7. The buffer strip 7 is used to reduce the collision when the mounting bases 3 move to the two ends.

[0038] The acquisition modules 1 are set up in pairs on two adjacent photovoltaic panels, and can collect surface data of the two photovoltaic panels respectively. By setting up a moving mechanism to install the acquisition modules 1, the two acquisition modules 1 in a pair can be periodically driven to switch positions, thereby switching the object of data collection. That is, a photovoltaic panel can be tested by different acquisition modules 1 in succession, and then they can be compared with each other. If one of the acquisition modules 1 fails, it can be identified in time, thus avoiding the problem of inaccurate data collection due to the failure to detect equipment failure in time, and effectively improving data accuracy.

[0039] Figure 2 and 5 -6 illustrates the second embodiment, the main difference from the first embodiment being that: the mounting base 3 includes a base plate 31 and a bent slide rod 32 fixedly connected to one side of its bottom. The bent slide rod 32 passes through the guide groove 4 and bends to hook onto the track plate 2. U-shaped rods 33 are fixedly connected to both the left and right sides of the bottom of the base plate 31, and a sleeve 34 is sleeved in the middle of the U-shaped rod 33 to reduce the resistance to sliding of the mounting base 3.

[0040] The drive assembly 5 includes an annular pull rope 51. The front and rear ends of the annular pull rope 51 are connected to the bent slide rods 32 of different mounting bases 3 via elastic bands 52. Both ends of the annular pull rope 51 are fitted with drive wheels 53, and one drive wheel 53 is driven by a servo motor. The inner side of the drive wheel 53 is provided with a rubber sleeve 54 to increase the friction with the annular pull rope 51. Guide wheels 55 are provided on one side of the drive wheel 53 and on both the front and rear sides of the annular pull rope 51 to guide the annular pull rope 51.

[0041] The track plate 2, drive wheel 53, servo motor and guide wheel 55 are all mounted on the base plate 8 and are mounted on the bottom surface or photovoltaic module through the base plate 8.

[0042] The mounting base 3 slides through the substrate 31. By rotating the annular pull rope 51 of the drive component 5, the front and rear sections move in opposite directions, which can drive the two sets of mounting bases 3 to move relative to each other. Moreover, one annular pull rope 51 can connect multiple pairs of mounting bases 3 on all photovoltaic panels to move together. That is, multiple moving mechanisms can share one drive component 5, which has better synchronization and is easier to control.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] When the moving mechanism is running, the servo motor is started to drive the drive wheel 53 to rotate, which in turn drives the ring pull rope 51 to rotate. The elastic belt 52 pulls the bent slide bar 32, which indirectly pulls the entire mounting base 3 and the acquisition module 1 on it to move along the guide groove 4, so that the two acquisition modules 1 switch positions with each other.
