Description

Technical Field

[0001] This invention relates to the field of photovoltaic tracker operation status processing technology, specifically a method for classifying and indicating the operation status of a photovoltaic tracker. Background Technology

[0002] Photovoltaic trackers are mostly deployed outdoors, and the types of abnormal triggers during operation are complex. Common abnormal situations include RTC clock synchronization failures, sensor acquisition failures, communication link timeouts, and electrical faults such as overcurrent and overvoltage. Photovoltaic trackers can also trigger environmental protection logic such as wind, rain, snow, hail protection, and flood protection, and have multiple operating modes including manual control, automatic tracking, and maintenance. Existing photovoltaic tracker operating status indication schemes generally rely on indicator lights to distinguish various operating states of the photovoltaic tracker, without setting up a status priority arbitration mechanism. However, if multiple operating states are triggered simultaneously, it will cause confusion in the indicator light output information, making it impossible for operators to accurately identify the true operating condition of the photovoltaic tracker. Summary of the Invention

[0003] To address the aforementioned shortcomings, this invention proposes a hierarchical indication method for the operating status of photovoltaic trackers. The aim is to solve the problem that existing photovoltaic tracker operating status indication schemes rely heavily on indicator lights to distinguish various operating statuses, without setting a status priority arbitration mechanism. If multiple operating statuses are triggered simultaneously, it will lead to confusion in the indicator light output prompts.

[0004] To achieve this objective, the present invention adopts the following technical solution: A method for indicating the hierarchical operation status of a photovoltaic tracker, the photovoltaic tracker including a photovoltaic tracker body and status indicator lights, the method comprising the following steps: Step S1: Obtain the multi-source operating status of the photovoltaic tracker body, including RTC status, communication status, sensor acquisition status, electrical status, environmental protection status, and working mode status. Step S2: Generate a candidate status code set based on the multi-source operating status and the preset status code generation rules; Step S3: According to the preset status priority sorting rules, select the target candidate status code with the highest priority from the candidate status code set, and determine the current running status level based on the target candidate status code; Step S4: Generate the corresponding indicator light code instruction based on the current operating status level; Step S5: Send the current indicator light code instruction to the status indicator light to complete the status indicator light prompt.

[0005] Preferably, in step S2, the preset status code generation rule is as follows: determine whether the RTC status, communication status, sensor acquisition status, electrical status, environmental protection status, and working mode status meet the corresponding preset trigger conditions. If yes, generate the corresponding candidate status code; if no, do not perform the generation operation. The preset trigger conditions include threshold determination, timeout count determination, consecutive abnormal number determination, verification result determination, and working mode setting determination.

[0006] Preferably, in step S3, the preset state priority sorting rule is specifically: safety protection shutdown state. Fault status Safety protection action status Manual or remote control status Communication error or RTC error status Automatic tracking status Warning or maintenance status Normal state.

[0007] Preferably, step S4 specifically includes the following sub-steps: If the current operating status level is normal, the generated indicator light code will be a solid green light or a regular flashing light. If the current operating status level is the warning level, the generated indicator light signal code will be a yellow light that flashes once per second. If the current operating status level is protection level, the generated indicator light code instruction is that the yellow light flashes once every 0.25 seconds, or flashes three times in a row and then pauses intermittently. If the current operating status level is fault level, the generated indicator light code instruction is for the red light to flash once every 0.25 seconds; If the current operating status level is maintenance level, the generated indicator light code instruction is that the red, yellow and green lights flash alternately, or the three-color lights are constantly on and then complete the flashing action within 1 second; If the current operating status level is offline or invalid, the generated indicator light code will be either light off or red light on.

[0008] Preferably, the method further includes the following step: storing the target candidate status code in the controller's built-in communication register of the photovoltaic tracker body.

[0009] Preferably, the method further includes the following steps: when a change in the current operating status level is detected, the status code corresponding to the changed operating status level and the status change timestamp are both written into the built-in log recording module of the controller of the photovoltaic tracker.

[0010] Preferably, the method further includes the following steps: when the current operating status level exits the fault level or protection level, the status priority arbitration is re-performed, and the system switches to a new operating status level.

[0011] The technical solution provided by this invention may include the following beneficial effects: This solution first acquires the multi-source operating status of the photovoltaic tracker; then, based on this multi-source operating status and preset status code generation rules, a candidate status code set is generated; next, according to preset status priority sorting rules, the highest priority target candidate status code is selected from the candidate status code set, and the current operating status level is determined accordingly; finally, a corresponding indicator light signal code instruction is generated based on the current operating status level and sent to the corresponding status indicator light for execution, realizing hierarchical and visual indication of the photovoltaic tracker's operating status. By setting status priority sorting rules, this solution arbitrates the priority of candidate status codes in multi-state concurrent scenarios, effectively avoiding confusion in light prompts when multiple operating states are triggered simultaneously, thereby improving the accuracy of staff in identifying the true operating condition of the photovoltaic tracker.

[0013] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0014] A method for indicating the hierarchical operation status of a photovoltaic tracker, the photovoltaic tracker including a photovoltaic tracker body and status indicator lights, the method comprising the following steps: Step S1: Obtain the multi-source operating status of the photovoltaic tracker body, including RTC status, communication status, sensor acquisition status, electrical status, environmental protection status, and working mode status. Step S2: Generate a candidate status code set based on the multi-source operating status and the preset status code generation rules; Step S3: According to the preset status priority sorting rules, select the target candidate status code with the highest priority from the candidate status code set, and determine the current running status level based on the target candidate status code; Step S4: Generate the corresponding indicator light code instruction based on the current operating status level; Step S5: Send the current indicator light code instruction to the status indicator light to complete the status indicator light prompt.

[0015] This solution provides a method for hierarchical indication of the operating status of a photovoltaic tracker, such as... Figure 1As shown, the first step is to acquire the multi-source operating status of the photovoltaic tracker itself. This multi-source operating status includes RTC clock status, communication status, sensor acquisition status, electrical status, environmental protection status, and operating mode status. In this embodiment, acquiring the multi-source operating status of the photovoltaic tracker provides a comprehensive and reliable data foundation for subsequent status classification indications. Further explanation: RTC status includes normal RTC timing, RTC timing failure, RTC uninitialized, RTC clock loss, RTC clock jump, and time drift. Communication status includes communication link timeout between the photovoltaic tracker and external devices or maintenance terminals, LoRa module malfunction, Zigbee module malfunction, and communication module initialization failure. Sensor acquisition status includes malfunctions of the tilt sensor, wind speed sensor, rain and snow sensor, and temperature and humidity sensor, and data from each sensor not being updated for a long time. Electrical status includes low battery power, undervoltage or overvoltage of the bus, motor overcurrent, and motor drive failure. Environmental protection status includes wind, rain, snow, hail protection triggering, and flood protection triggering. The operating modes include automatic tracking mode, remote control mode, leveling mode, manual control mode, and maintenance mode. The second step is to generate a candidate status code set based on the multi-source operating status and preset status code generation rules. In this embodiment, the operating status of each dimension is encoded and converted according to the preset status code generation rules to uniformly output standardized status codes, providing standardized and comparable data support for subsequent multi-state priority screening. The third step is to select the highest priority target candidate status code from the candidate status code set according to the preset status priority sorting rules, and determine the current operating status level based on this target candidate status code. In this embodiment, by selecting the highest priority target candidate status code from the candidate status code set according to the preset status priority sorting rules, the most urgent operating condition of the photovoltaic tracker can be accurately located, prioritizing the display of critical faults, high-risk anomalies, and important operating modes. The candidate status code includes fields such as status level, status source, specific status item, action suggestion, hold flag, and timestamp. By determining the current operating status level based on the target candidate status code, it is possible to quickly distinguish between different levels of equipment operating conditions, such as normal, warning, protection, fault, and maintenance, providing a hierarchical basis for subsequently generating differentiated indicator light code instructions. The fourth step is to generate corresponding indicator light code instructions based on the current operating status level. In this embodiment, by matching and generating corresponding indicator light code instructions based on the current operating status level, different types of photovoltaic tracker operating conditions correspond to differentiated light instructions, facilitating subsequent intuitive and clear differentiation of various photovoltaic tracker operating conditions.The fifth step is to send the current indicator light code instruction to the status indicator light to complete the light prompt of the status indicator light. In this embodiment, by sending the indicator light code instruction to the status indicator light and completing the light prompt output, the complex operating status of the photovoltaic tracker can be visualized and displayed intuitively, allowing maintenance personnel to quickly grasp the current core operating status of the photovoltaic tracker.

[0016] This solution first acquires the multi-source operating status of the photovoltaic tracker; then, based on this multi-source operating status and preset status code generation rules, a candidate status code set is generated; next, according to preset status priority sorting rules, the highest priority target candidate status code is selected from the candidate status code set, and the current operating status level is determined accordingly; finally, a corresponding indicator light signal code instruction is generated based on the current operating status level and sent to the corresponding status indicator light for execution, realizing hierarchical and visual indication of the photovoltaic tracker's operating status. By setting status priority sorting rules, this solution arbitrates the priority of candidate status codes in multi-state concurrent scenarios, effectively avoiding confusion in light prompts when multiple operating states are triggered simultaneously, thereby improving the accuracy of staff in identifying the true operating condition of the photovoltaic tracker.

[0017] Preferably, in step S2, the preset status code generation rule is as follows: determine whether the RTC status, communication status, sensor acquisition status, electrical status, environmental protection status, and working mode status meet the corresponding preset trigger conditions. If yes, generate the corresponding candidate status code; if no, do not perform the generation operation. The preset trigger conditions include threshold determination, timeout count determination, consecutive abnormal number determination, verification result determination, and working mode setting determination.

[0018] In this embodiment, trigger condition verification is carried out for six types of operating conditions: RTC status, communication status, sensor acquisition status, electrical status, environmental protection status, and working mode status. Once any operating condition reaches the corresponding preset trigger condition, an exclusive candidate status code can be generated independently, which can completely capture the information of the photovoltaic tracker in all dimensions of normal, abnormal, protection, and working modes.

[0019] In one embodiment, when the real-time wind speed value collected by the wind speed sensor is greater than the preset strong wind protection threshold, and the over-limit state occurs consecutively a preset number of times, a "strong wind protection" candidate status code is generated. When the communication link fails to receive a valid communication frame for M consecutive cycles, or when multiple consecutive frames of communication data fail to be verified, a "communication error" candidate status code is generated. When the power supply battery level is lower than the preset low power threshold and continues for a preset time, a candidate status code for "low power supply battery warning" will be generated. When overcurrent, stall, mechanical limit, or motor parameter verification fails during motor drive, a candidate status code "motor drive failure or protection shutdown" is generated. When the RTC is not initialized, timing fails, or RTC read / write is abnormal, an "RTC error" candidate status code is generated. When the photovoltaic tracker is in automatic tracking mode and no abnormal operating conditions are triggered, a candidate status code of "normal automatic tracking" is generated; when the photovoltaic tracker is in manual control mode, remote control mode, leveling mode, or maintenance mode, a candidate status code of the corresponding type of working mode is generated.

[0020] Preferably, in step S3, the preset state priority sorting rule is as follows: safety protection shutdown state Fault status Safety protection action status Manual or remote control status Communication error or RTC error status Automatic tracking status Warning or maintenance status Normal state.

[0021] In this embodiment, by setting a priority ranking rule based on the safety risk and the urgency of operation and maintenance, the system can prioritize the photovoltaic tracker device with the greatest safety risks and the highest urgency of operation and maintenance when multiple operating states occur concurrently.

[0022] Preferably, step S4 specifically includes the following sub-steps: If the current operating status level is normal, the generated indicator light code will be a solid green light or a regular flashing light. If the current operating status level is the warning level, the generated indicator light signal code will be a yellow light that flashes once per second. If the current operating status level is protection level, the generated indicator light code instruction is that the yellow light flashes once every 0.25 seconds, or flashes three times in a row and then pauses intermittently. If the current operating status level is fault level, the generated indicator light code instruction is for the red light to flash once every 0.25 seconds; If the current operating status level is maintenance level, the generated indicator light code instruction is that the red, yellow and green lights flash alternately, or the three-color lights are constantly on and then complete the flashing action within 1 second; If the current operating status level is offline or invalid, the generated indicator light code will be either light off or red light on.

[0023] In this embodiment, a multi-level visual status prompting system is constructed based on light color, flashing frequency, and multi-color combination patterns. Specifically, green light is used to represent the normal operating condition of the equipment; different flashing frequencies of yellow light are used to distinguish between warning conditions and environmental safety protection conditions; high-frequency flashing of red light is used to indicate equipment fault conditions such as motor overcurrent, motor drive failure, tilt sensor abnormality, and RTC abnormality; a combination of red, yellow, and green light is used to indicate maintenance conditions; and the lights being off or constantly lit in red indicate abnormal conditions such as equipment being offline or shut down.

[0024] Preferably, the method further includes the following step: storing the target candidate status code in the built-in communication register of the controller of the photovoltaic tracker. In this embodiment, by storing the target candidate status code in the built-in communication register of the controller of the photovoltaic tracker, maintenance personnel only need to read the address of the communication register through a conventional communication protocol on a remote platform to obtain the target candidate status code, without having to go to the site to check the status indicator lights to know the operating status of the photovoltaic tracker equipment.

[0025] Preferably, the method further includes the following steps: when a change in the current operating status level is detected, the status code corresponding to the changed operating status level and the status change timestamp are both written to the built-in log recording module of the photovoltaic tracker's controller. In this embodiment, the log recording module is a dedicated log storage unit inside the controller of the photovoltaic tracker. By writing the status code corresponding to the changed operating status level and the status change timestamp to the log recording module, it is possible to ensure that the stored status change records are not lost in scenarios such as communication interruption or temporary power outage of the equipment; on the other hand, it is convenient for maintenance personnel to quickly retrieve and trace the timing information of previous status changes of the equipment.

[0026] Preferably, the method further includes the following steps: when the current operating status level exits the fault level or protection level, the status priority arbitration is re-performed, and the system switches to the new operating status level. In this embodiment, when the photovoltaic tracker device exits the fault level and protection level, the priority arbitration logic is automatically restarted, and the operating status level is updated synchronously. This avoids maintenance personnel from misjudging that the photovoltaic tracker device is still in an abnormal state, and ensures that the status indicator lights match the actual operating conditions of the photovoltaic tracker in real time.

[0027] Furthermore, the functional units in the various embodiments of the present invention can be integrated into a processing module, or each unit can exist physically separately, or two or more units can be integrated into a module. The integrated module can be implemented in hardware or as a software functional module. If the integrated module is implemented as a software functional module and sold or used as an independent product, it can also be stored in a computer-readable storage medium.

[0028] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
