In addition, the term "including" and its variants are to be interpreted as open-ended terms meaning "including but not limited to".

[0049] In order to solve the above technical problems, the present application provides a method for remote temperature monitoring of photovoltaic power generation, such as Figure 1 As shown, the photovoltaic power generation temperature remote monitoring method may include the following steps S101 and S102:

[0050] Step S101 , monitoring the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel.

[0051] In this step, the sensor may be a temperature sensor, which may be configured on the photovoltaic panel, and the temperature sensor may collect the temperature on the photovoltaic panel.

[0052] Step S102, when it is monitored that the current temperature of the sensor of the photovoltaic panel is greater than the first temperature control threshold, the sprinkler head is controlled to spray water on the photovoltaic panel, and the spraying is stopped when the spraying time is reached, and the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel are continued to be monitored; wherein the spraying time is calculated based on the current light intensity of the installation site of the photovoltaic panel.

[0053] In this step, the first temperature control threshold is in the range of 20° C. to 30° C., for example, the first temperature control threshold is 25° C., etc., which is not limited in this embodiment.

[0054] The embodiment of the present application can automatically monitor the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel, and dynamically set the first temperature control threshold. When it is monitored that the current temperature of the sensor of the photovoltaic panel is greater than the first temperature control threshold, the sprinkler head configured for the photovoltaic panel is automatically controlled to spray water on the photovoltaic panel, thereby achieving the purpose of automatically and efficiently cooling the photovoltaic panel, solving the problem that the existing water spraying cooling is manually performed, with a large workload and low efficiency; in addition, the present embodiment dynamically adjusts the threshold for triggering the sprinkler head to spray water on the photovoltaic panel, thereby achieving precise water spraying cooling and reducing the waste of water resources.

[0055] The present application provides a possible implementation method. The above step S101 monitors the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel, which may specifically include the following steps A1 and A2:

[0056] Step A1: The remote system remotely collects the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel at a set period.

[0057] In this step, the set period can be set according to actual needs, such as setting the period to 30 minutes or 60 minutes, etc., which is not limited in this embodiment.

[0058] Step A2, monitoring the collected temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel.

[0059] This embodiment automatically collects the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel through a remote system without manual intervention, thereby improving the accuracy and efficiency of data collection.

[0060] The present application provides a possible implementation method, and the water spraying time can be calculated according to the current light intensity of the photovoltaic panel installation site using the following formula:

[0061] Water spraying duration = preset basic duration + (current light intensity - 5000) / 1000 * 0.5

[0062] In the formula, the unit of the current light intensity is lux, the units of 5000 and 1000 are both lux, and the units of the water spraying duration and the preset basic duration are both minutes. Here, lux is the unit of light intensity, indicating the luminous flux received per square meter. The preset basic duration here can be set according to actual needs, such as the preset basic duration is 1 minute, etc., and this embodiment does not limit this.

[0063] A possible implementation method is provided in the embodiment of the present application, and may further include the following steps B1:

[0064] Step B1: if the calculated water spraying time is greater than the first set time, the water spraying time is set to the first set time.

[0065] In this step, the first set time length can be set according to actual needs, such as the first set time length is 3 minutes or 5 minutes, etc., which is not limited in this embodiment.

[0066] The present application provides a possible implementation method, which may further include the following steps C1 and C2 after the water spraying is finished in the above step S102:

[0067] Step C1, obtaining the lowest temperature within a second set time period after the water spraying ends.

[0068] In this step, the second set time length can be set according to actual needs, such as the second set time length is 5 minutes, etc., which is not limited in this embodiment.

[0069] Step C2, determining the second temperature control threshold for subsequent triggering of water spraying based on the minimum temperature, so that when the current temperature of the sensor monitoring the photovoltaic panel is greater than the second temperature control threshold, the sprinkler head is controlled to spray water on the photovoltaic panel, and the spraying is ended when the spraying time is reached, wherein the spraying time is calculated based on the current light intensity of the installation site of the photovoltaic panel.

[0070] In this step, the lowest temperature plus one degree can be used as the second temperature control threshold for subsequent triggering of water spraying. It can be seen that this embodiment dynamically adjusts the threshold for subsequent triggering of the water spray head to spray water on the photovoltaic panel, achieving precise water spraying and cooling, and reducing the waste of water resources.

[0071] A possible implementation method is provided in the embodiment of the present application, and may further include the following steps D1:

[0072] Step D1, obtaining the time when the sun sets, and when the time when the sun sets is reached, adjusting the temperature control threshold for subsequent triggering of water spraying to the first temperature control threshold.

[0073] Generally speaking, the power generation effect of photovoltaic panels is usually considered to be optimal when the surface temperature is between 20℃ and 25℃. Therefore, when the sun sets, the temperature control threshold for triggering subsequent water spraying can be adjusted to the first temperature control threshold, for example, the first temperature control threshold is 25℃, etc. This embodiment does not limit this.

[0074] The above introduces Figure 1 There are various implementation methods for each link of the illustrated embodiment. The temperature remote monitoring method for photovoltaic power generation according to the embodiment of the present application will be further explained below through specific embodiments.

[0075] Figure 2 FIG. 1 is a flow chart showing a method for remotely monitoring the temperature of photovoltaic power generation provided by another embodiment of the present application. Figure 2 As shown, the photovoltaic power generation temperature remote monitoring method may include the following steps S201 to S205:

[0076] Step S201 : The remote system remotely collects the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel at a set period.

[0077] In this step, the set period can be set according to actual needs, such as setting the period to 15 minutes, 30 minutes or 60 minutes, etc., which is not limited in this embodiment.

[0078] Step S202 , monitoring the collected temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel.

[0079] Step S203, when it is monitored that the current temperature of the sensor of the photovoltaic panel is greater than the first temperature control threshold, the sprinkler head is controlled to spray water on the photovoltaic panel, and the spraying is stopped when the spraying time is reached, wherein the spraying time is calculated based on the current light intensity of the installation site of the photovoltaic panel.

[0080] In this step, the first temperature control threshold is in the range of 20° C. to 30° C., for example, the first temperature control threshold is 25° C., etc., which is not limited in this embodiment.

[0081] In addition, the water spraying duration can be calculated according to the current light intensity at the installation site of the photovoltaic panel using the following formula:

[0082] Water spraying duration = preset basic duration + (current light intensity - 5000) / 1000 * 0.5

[0083] In the formula, the unit of the current light intensity is lux, the units of 5000 and 1000 are both lux, and the units of the water spraying duration and the preset basic duration are both minutes. Here, lux is the unit of light intensity, indicating the luminous flux received per square meter. The preset basic duration here can be set according to actual needs, such as the preset basic duration is 0 minutes or 1 minute, etc., and this embodiment does not limit this.

[0084] Here, the duration of a single water spraying does not exceed 3 minutes, that is, if the calculated water spraying duration is greater than 3 minutes, the water spraying duration is set to 3 minutes.

[0085] Step S204, the remote system obtains the lowest temperature within a second set time period after the water spraying ends.

[0086] In this step, the second set time length can be set according to actual needs, such as the second set time length is 5 minutes, etc., which is not limited in this embodiment.

[0087] Step S205, adding one degree to the lowest temperature as the second temperature control threshold for subsequently triggering water spraying.

[0088] That is to say, continue to monitor the collected temperature of the photovoltaic panel sensor and the light intensity of the installation site of the photovoltaic panel; when it is monitored that the current temperature of the photovoltaic panel sensor is greater than the second temperature control threshold, control the sprinkler head to spray water on the photovoltaic panel, and end the spraying when the spraying time is reached, wherein the spraying time is calculated based on the current light intensity of the installation site of the photovoltaic panel; thereafter, the remote system obtains the lowest temperature within the second set time after the end of the water spraying, adds one degree to the lowest temperature, and uses it as the third temperature control threshold for subsequent triggering of the water spraying.

[0089] By analogy, the collected temperature of the photovoltaic panel sensor and the light intensity of the installation site of the photovoltaic panel continue to be monitored; when the current temperature of the photovoltaic panel sensor is monitored to be greater than the third temperature control threshold, the sprinkler head is controlled to spray water on the photovoltaic panel, and the spraying is ended when the spraying time is reached, wherein the spraying time is calculated based on the current light intensity of the installation site of the photovoltaic panel; thereafter, the remote system obtains the lowest temperature within the second set time after the end of the water spraying, and adds one degree to the lowest temperature as the fourth temperature control threshold for subsequent triggering of the water spraying.

[0090] In addition, the time when the sun sets can be obtained, and when the time when the sun sets is reached, the temperature control threshold for triggering the subsequent water spraying is adjusted to the first temperature control threshold.

[0091] Generally speaking, the power generation effect of photovoltaic panels is usually considered to be optimal when the surface temperature is between 20℃ and 25℃. Therefore, when the sun sets, the temperature control threshold for triggering subsequent water spraying can be adjusted to the first temperature control threshold, for example, the first temperature control threshold is 25℃, etc. This embodiment does not limit this.

[0092] This embodiment can automatically monitor the temperature of the sensor of the photovoltaic panel and the light intensity of the installation site of the photovoltaic panel through a remote system, and dynamically set a first temperature control threshold. When it is monitored that the current temperature of the sensor of the photovoltaic panel is greater than the first temperature control threshold, the sprinkler head configured for the photovoltaic panel is automatically controlled to spray water on the photovoltaic panel, thereby achieving the purpose of automatically and efficiently cooling the photovoltaic panel, solving the problem that the existing water spraying cooling is manually performed, with a large workload and low efficiency; in addition, this embodiment dynamically adjusts the threshold for subsequently triggering the sprinkler head to spray water on the photovoltaic panel, thereby achieving precise water spraying cooling and reducing the waste of water resources.

[0093] It should be noted that the size of the sequence number of each step in the above embodiment does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application. In practical applications, all the above possible implementation methods can be combined in any way to form possible embodiments of the present application, which will not be described one by one here.
