Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on the structures shown in these drawings.

[0049] Figure 1 It is a flowchart of the steps of the first embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0050] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0051] The present invention proposes a temperature control method and system for an energy storage cabinet based on spatial nodes.

[0052] As shown in the attached Figure 1As shown, in the first embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, this method is applied to a temperature control system for an energy storage cabinet based on spatial nodes; the system includes an energy storage cabinet, temperature sensors, an air conditioner, an air outlet pipe, and a server; the number of the temperature sensors is multiple; the multiple temperature sensors are respectively arranged at various places inside the energy storage cabinet; the air outlet pipe is arranged around the inside of the energy storage cabinet, the air outlet pipe is provided with multiple air outlets, and each air outlet is correspondingly provided with a solenoid valve; the solenoid valve is used to close or open the corresponding air outlet; the air outlet pipe is communicated with the air outlet end of the air conditioner; the solenoid valve, the temperature sensor, and the air conditioner are all communicatively connected to the server; this embodiment includes the following steps:

[0053] Step S110: The server obtains the real-time temperature values detected by each of the temperature sensors.

[0054] Step S120: The server obtains a temperature upper threshold (for example, 50°C).

[0055] Specifically, when the temperature inside the energy storage cabinet is higher than the temperature upper threshold, the working safety risk of the energy storage cabinet will increase. Therefore, it is necessary to ensure that the temperature inside the energy storage cabinet is lower than the temperature upper threshold.

[0056] Step S130: The server marks the temperature sensors whose real-time temperature values detected in the past first preset duration (for example, 10 seconds) are always greater than the temperature upper threshold as first target sensors.

[0057] Specifically, if the real-time temperature value detected by a certain temperature sensor in the past 10 seconds is always greater than the temperature upper threshold, it means that the area inside the cabinet where the sensor is located is a high-temperature area and needs to be cooled down.

[0058] Step S140: The server marks the two air outlets closest to the first target sensor as the first air outlet and the second air outlet respectively, where the first air outlet and the second air outlet are respectively on both sides of the first target sensor.

[0059] Step S150: The server marks the solenoid valve corresponding to the first air outlet as the first solenoid valve and marks the solenoid valve corresponding to the second air outlet as the second solenoid valve.

[0060] Step S160: The server controls the air conditioner to start for refrigeration.

[0061] Specifically, start the air conditioner and perform targeted cooling on the high-temperature area through the first air outlet and the second air outlet.

[0062] Step S170: The server controls the first solenoid valve to open the first air outlet and controls the second solenoid valve to open the second air outlet.

[0063] The energy storage cabinet temperature control method based on spatial nodes proposed by the present invention can solve the problems that the traditional energy storage cabinet temperature control method mainly relies on manual monitoring, has a slow response speed, and is prone to errors. Specifically, when in use, temperature sensors are respectively arranged at various places in the energy storage cabinet to monitor the temperature at various places in the energy storage cabinet in real time, so as to obtain the temperature values of each spatial node in the energy storage cabinet in real time. And the temperature sensors whose real-time temperature values detected in the past first preset time period are always greater than the upper temperature threshold are marked as the first target sensors, that is, the cabinet area where the first target sensors are located is the high-temperature area. Then, the two air outlets closest to the first target sensors are respectively marked as the first air outlet and the second air outlet, and then the air conditioner is started to refrigerate, the first solenoid valve is controlled to open the first air outlet, and the second solenoid valve is controlled to open the second air outlet, so as to perform targeted cooling and heat dissipation on the high-temperature area where the first target sensors are located. The response speed of the temperature control process in the whole process is faster, without manual intervention, and is more efficient and intelligent.

[0064] In the second embodiment of the energy storage cabinet temperature control method based on spatial nodes proposed by the present invention, based on the first embodiment, a plurality of first installation points and a plurality of second installation points are arranged in the energy storage cabinet; all the first installation points are on the same horizontal plane; all the second installation points are on the same horizontal plane; one temperature sensor is correspondingly arranged at each first installation point; one temperature sensor is correspondingly arranged at each second installation point. Such a setting can make the distribution of the temperature sensors more uniform.

[0065] In the third embodiment of the energy storage cabinet temperature control method based on spatial nodes proposed by the present invention, based on the first embodiment, step S160 includes the following steps:

[0066] Step S310: The server determines whether the number of the first target sensors is a preset number, where the preset number is the total number of the temperature sensors.

[0067] If so, execute step S320: The server controls the air conditioner to start refrigerating, and the refrigeration power is the maximum rated refrigeration power.

[0068] Specifically, if all the temperature sensors are first target sensors, it means that the temperatures at all places in the entire energy storage cabinet are relatively high, and a greater power is required for refrigeration.

[0069] If not, execute step S330: The server determines the actual refrigeration power of the air conditioner based on the number of the first target sensors.

[0070] Specifically, if not, it indicates that only some of the temperature sensors are the first target sensors, indicating that the cooling demand of the entire energy storage cabinet is not strong. Therefore, the actual cooling power of the air conditioner is determined based on the number of the first target sensors.

[0071] In the fourth embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, based on the third embodiment, the calculation formula for the server to determine the actual cooling power of the air conditioner based on the number of the first target sensors is:

[0072]

[0073] In the formula, P S is the actual cooling power of the air conditioner; P MAX is the maximum rated cooling power of the air conditioner; S 1 is the number of the first target sensors; S Y is the preset number.

[0074] Specifically, this embodiment provides a technical solution for determining the actual cooling power of the air conditioner based on the number of the first target sensors.

[0075] In the fifth embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, based on the first embodiment, after step S170, the following steps are further included:

[0076] Step S510: After the air conditioner starts and runs for a second preset duration (for example, 60 seconds), the server acquires the real-time temperature values detected by the first target sensors within the second preset duration and marks them as the first feedback temperature values, where the number of the first feedback temperature values is multiple.

[0077] Step S520: The server determines whether the last one of the first feedback temperature values within the second preset duration is less than the upper temperature threshold.

[0078] If not, execute step S530: The server increases the cooling power of the air conditioner.

[0079] Specifically, when the air conditioner starts and runs for the second preset duration, the temperature inside the energy storage cabinet should drop. If the last one of the first feedback temperature values within the second preset duration is less than the upper temperature threshold, it indicates that the temperature inside the energy storage cabinet has dropped to a reasonable range; otherwise, it indicates that the temperature inside the energy storage cabinet is still at a relatively high level and the cooling power needs to be further increased to improve the cooling effect.

[0080] In the sixth embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, based on the fifth embodiment, after step S510, the following steps are further included:

[0081] Step S610: The server marks the last first feedback temperature value within the second preset duration and the previous preset number (e.g., 20) of first feedback temperature values as the first temperature values to be analyzed.

[0082] Specifically, the acquisition interval duration of the temperature sensor here is 1 second, that is, the temperature value is acquired every 1 second; then, by analyzing the first temperature values to be analyzed, it can be known whether the temperature in the energy storage cabinet has stabilized.

[0083] Step S620: The server determines whether the first condition is satisfied, where the first condition is that the difference between the maximum first temperature value to be analyzed and the minimum first temperature value to be analyzed is less than the first preset difference (e.g., 2°C).

[0084] Specifically, if the first condition is satisfied, it indicates that the temperature in the energy storage cabinet has stabilized.

[0085] If so, execute Step S630: The server obtains the average value of the first temperature values to be analyzed.

[0086] Step S640: The server determines whether the second condition is satisfied, where the second condition is that the difference between the average value of the first temperature values to be analyzed and the preset temperature value (the preset temperature value here is the ideal temperature value when the energy storage cabinet operates normally, e.g., 25°C) is less than the second preset difference (e.g., 3°C).

[0087] Specifically, after the first condition is satisfied, it is further determined whether the first temperature values to be analyzed satisfy the second condition; if the second condition is satisfied, it indicates that the temperature in the area where the first target sensor is located has tended to stabilize and is stable within a suitable temperature range, and there is no need to adjust the operating power of the air conditioner.

[0088] Step S650: If satisfied, the server controls the air conditioner to continue operating at the current operating power.

[0089] In the seventh embodiment of a method for controlling the temperature of an energy storage cabinet based on spatial nodes proposed in the present invention, based on the sixth embodiment, after Step S640, the following steps are further included:

[0090] Step S710: If not satisfied, the server generates an adjustment instruction.

[0091] Specifically, it is further analyzed whether the first temperature values to be analyzed satisfy the second condition; if the second condition is not satisfied, it indicates that although the temperature in the area where the first target sensor is located has tended to stabilize, it is not stable within a suitable temperature range, and the operating power of the air conditioner still needs to be further adjusted.

[0092] Step S720: When the average value of the first temperature value to be analyzed is greater than the preset temperature value, the server increases the cooling power of the air conditioner based on the adjustment instruction.

[0093] Specifically, when the average value of the first temperature value to be analyzed is greater than the preset temperature value, it indicates that further cooling is required, so the cooling power of the air conditioner is increased.

[0094] Step S730: When the average value of the first temperature value to be analyzed is less than the preset temperature value, the server decreases the cooling power of the air conditioner based on the adjustment instruction.

[0095] Specifically, when the average value of the first temperature value to be analyzed is less than the preset temperature value, it indicates that the current cooling effect of the air conditioner is excessive, so the cooling power of the air conditioner is decreased.

[0096] In the eighth embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, based on the first embodiment, the system further includes a heating wire disposed in the interlayer of the energy storage cabinet; the heating wire is divided into a plurality of heating wire segments that can work independently of each other; the server is further configured to control the start and stop of the heating wire; after step S110, the following steps are further included:

[0097] Step S810: The server obtains a temperature lower threshold value (for example, 0 °C).

[0098] Specifically, when the temperature inside the energy storage cabinet is lower than the temperature lower threshold value (for example, the energy storage cabinet is set in a severely cold area or the current season is winter), it will affect the charge and discharge efficiency of the energy storage cabinet. Therefore, it is necessary to ensure that the temperature inside the energy storage cabinet is higher than the temperature lower threshold value.

[0099] Step S820: The server marks the temperature sensors whose real-time temperature values detected in the past first preset duration are always less than the temperature lower threshold value as second target sensors.

[0100] Specifically, if the real-time temperature value detected by a certain temperature sensor in the past 10 seconds is always less than the temperature lower threshold value, it indicates that the cabinet area where the sensor is located is a low-temperature area and needs to be heated up.

[0101] Step S830: The server marks the heating wire segment closest to the second target sensor as the target heating wire segment.

[0102] Step S840: The server controls the target heating wire segment to start for heating.

[0103] In the ninth embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, based on the eighth embodiment, after step S840, the following steps are further included:

[0104] Step S910: After the target heating wire segment starts and operates for a second preset duration, the server acquires the real-time temperature values detected by the second target sensor within the second preset duration and marks them as second feedback temperature values, where the number of the second feedback temperature values is multiple.

[0105] Step S920: The server determines whether the last one of the second feedback temperature values within the second preset duration is greater than the lower temperature threshold.

[0106] If not, execute Step S930: The server increases the heating power of the target heating wire segment.

[0107] Specifically, when the target heating wire segment starts heating and operates for the second preset duration, the temperature inside the energy storage cabinet should rise. If the last one of the second feedback temperature values within the second preset duration is greater than the lower temperature threshold, it indicates that the temperature inside the energy storage cabinet has risen to a reasonable range; otherwise, it indicates that the temperature inside the energy storage cabinet is still at a relatively low level and the heating power needs to be further increased to improve the heating effect.

[0108] In the tenth embodiment of a temperature control method for an energy storage cabinet based on spatial nodes proposed by the present invention, based on the first embodiment, the system further includes a mobile terminal communicatively connected to the server; after Step S160, the following steps are further included:

[0109] Step S1010: The server generates a high-temperature warning message, where the high-temperature warning message includes the number of the first target sensor, the numbers of the first air outlet and the second air outlet, and the current operating power of the air conditioner.

[0110] Step S1020: The server sends the high-temperature warning message to the mobile terminal.

[0111] The present invention also proposes a temperature control system for an energy storage cabinet based on spatial nodes, which applies the temperature control method for an energy storage cabinet based on spatial nodes; the system includes an energy storage cabinet, temperature sensors, an air conditioner, an air duct, and a server; the number of the temperature sensors is multiple; the multiple temperature sensors are respectively arranged at various places inside the energy storage cabinet; the air duct is arranged around the inside of the energy storage cabinet, the air duct is provided with a plurality of air outlets, and a solenoid valve is correspondingly arranged at each air outlet; the solenoid valve is used to close or open the corresponding air outlet; the air duct is communicated with the air outlet end of the air conditioner; the solenoid valve, the temperature sensor, and the air conditioner are all communicatively connected to the server.
