Description

Technical Field

[0001] This invention belongs to the field of flexible charging pile heat dissipation management technology, specifically relating to an automatic dust removal control method and device for flexible charging piles. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Flexible charging piles are power-concentrated devices, and during use, the internal rectifier modules generate a large amount of heat. Currently, most flexible charging piles use forced air cooling for heat dissipation. By installing filters at the air inlets of the cooling ducts, dust and willow catkins are prevented from being drawn into the rectifier modules inside the flexible charging pile. However, dust and catkins accumulate on the filters over time and can clog the air inlets, requiring maintenance personnel to manually clean the filters periodically.

[0004] Over time, the accumulation of objects adsorbed on the filter screen can clog the air inlet, affecting the heat dissipation of the flexible charging pile, causing internal high temperatures, resulting in a decrease in the power of the flexible charging pile, and a reduction in the lifespan of electronic components. The accumulated objects will solidify and stick together after experiencing the rainy season or humid environment, becoming difficult to clean. Manual cleaning and maintenance are difficult and will increase maintenance costs. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes an automatic dust removal control method and device for flexible charging piles. After each operation of the flexible charging pile, automatic dust removal is performed. The residual heat of the rectifier module inside the flexible charging pile is used to dry the damp dust and willow catkins adsorbed at the air inlet and blow them away from the filter screen, thereby reducing the accumulation of dust and willow catkins, minimizing the impact on equipment heat dissipation, and extending the service life and efficiency of the equipment.

[0006] According to some embodiments, the first aspect of the present invention provides an automatic dust removal control method for flexible charging piles, which adopts the following technical solution:

[0007] An automatic dust control method for flexible charging piles includes:

[0008] Obtain the operating parameters of the flexible charging pile;

[0009] The state of the flexible charging pile is determined based on the acquired operating parameters;

[0010] When the flexible charging pile is in operation, the bidirectional axial flow fan is controlled to enter the heat dissipation mode; when the flexible charging pile is detected to have stopped working, the bidirectional axial flow fan is controlled to enter the dust removal mode.

[0011] In dust removal mode, when the flexible charging pile is detected to be in working state, the bidirectional axial flow fan is controlled to stop dust removal and then enter the heat dissipation mode; when the flexible charging pile is not detected to be in working state, the bidirectional axial flow fan is controlled to remove dust and then enter the standby state.

[0012] As a further technical limitation, the obtained operating parameters of the flexible charging pile include the flexible charging pile heat dissipation control level signal, the inlet temperature of the flexible charging pile bidirectional axial flow fan, and the outlet temperature of the flexible charging pile bidirectional axial flow fan.

[0013] Furthermore, the flexible charging pile is in a working state and a standby state; when the acquired flexible charging pile heat dissipation control level signal is high, the flexible charging pile is in a standby state, and when the acquired flexible charging pile heat dissipation control level signal is low, the flexible charging pile is in a working state.

[0014] As a further technical limitation, the dust removal modes include fixed dust removal mode, temperature-controlled dust removal mode, and working condition dust removal mode.

[0015] As a further technical limitation, when the flexible charging pile is in operation, the bidirectional axial flow fan is controlled to enter the heat dissipation mode. Based on the temperature difference between the air inlet and outlet of the bidirectional axial flow fan, the number of fan groups activated in the heat dissipation mode is determined.

[0016] As a further technical limitation, in the heat dissipation mode, when the heat dissipation control level signal of the flexible charging pile changes from low level to high level, the flexible charging pile stops working and changes from working state to standby state. The bidirectional axial flow fan is controlled to stop heat dissipation, and after a preset commutation interval waiting time for the bidirectional axial flow fan, the bidirectional axial flow fan is controlled to enter the dust removal mode.

[0017] As a further technical limitation, in the dust removal mode, when the flexible charging pile heat dissipation control level signal is detected to change from high level to low level, the flexible charging pile starts to work, changes from standby state to working state, controls the bidirectional axial flow fan to stop dust removal, and after a preset bidirectional axial flow fan reversal interval waiting time, controls the bidirectional axial flow fan to enter the heat dissipation mode.

[0018] Furthermore, in dust removal mode, when no change from high to low level of the flexible charging pile heat dissipation control signal is detected, the flexible charging pile continues to be in dust removal mode. After dust removal is completed, the bidirectional axial flow fan is stopped and the flexible charging pile is in standby mode.

[0019] According to some embodiments, a second aspect of the present invention provides an automatic dust removal control device for flexible charging piles, which executes the automatic dust removal control method for flexible charging piles provided in the first aspect, and adopts the following technical solution:

[0020] An automatic dust removal control device for a flexible charging pile includes a main control module and a data acquisition module and a bidirectional fan control module respectively connected to the main control module. The main control module is used to process the signals acquired by the data acquisition module and coordinate the automatic dust removal control device for the flexible charging pile to complete the dust removal function. The bidirectional fan control module is used to control the airflow direction of the bidirectional axial flow fan to realize the mutual conversion between heat dissipation and dust removal.

[0021] As a further technical limitation, the acquisition module includes a flexible charging pile operating status signal acquisition module and a temperature acquisition module; the flexible charging pile automatic dust removal control device also includes a DIP switch module and a power supply module respectively connected to the main control module.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention automatically performs dust removal after each operation of the flexible charging pile. It utilizes the residual heat of the rectifier module inside the flexible charging pile to dry the damp dust and willow catkins adsorbed at the air inlet and blow them away from the filter screen, thereby reducing the accumulation of dust and willow catkins, reducing the impact on equipment heat dissipation, and extending the service life and efficiency of the equipment.

[0032] Example 1

[0033] Embodiment 1 of this invention introduces an automatic dust removal control method for flexible charging piles.

[0034] like Figure 1 and Figure 2 An automatic dust removal control method for a flexible charging pile, as shown, includes:

[0035] Obtain the operating parameters of the flexible charging pile;

[0036] The state of the flexible charging pile is determined based on the acquired operating parameters;

[0037] When the flexible charging pile is in operation, the bidirectional axial flow fan is controlled to enter the heat dissipation mode; when the flexible charging pile is detected to have stopped working, the bidirectional axial flow fan is controlled to enter the dust removal mode.

[0038] In dust removal mode, when the flexible charging pile is detected to be in working state, the bidirectional axial flow fan is controlled to stop dust removal and then enter the heat dissipation mode; when the flexible charging pile is not detected to be in working state, the bidirectional axial flow fan is controlled to remove dust and then enter the standby state.

[0039] In the automatic dust removal control process of flexible charging piles, the operating parameters of the device must first be set through the DIP switch module, including:

[0040] 1) Set the interval time for AC bidirectional axial fan reversal to protect the fan, prevent the fan from reversing during operation, and extend the fan's lifespan. The default interval time is 60 seconds.

[0041] 2) Set the fixed dust removal duration in the fixed dust removal mode, which is 3 minutes by default.

[0042] 3) Set the threshold for the temperature difference between the inlet and outlet air when the dust removal starts in temperature-controlled dust removal mode. The default starting temperature difference is ≥5℃. Starting temperature difference = outlet air temperature - inlet air temperature. After the dust removal starts, the stopping temperature difference is judged to be ≤1℃. Stopping temperature difference = inlet air temperature - outlet air temperature.

[0043] 4) Under the setting of the working condition dust removal mode, the required running time of the flexible charging pile to activate the dust removal mode is set. The default is that the flexible charging pile starts dust removal after running for ≥10 minutes. The dust removal running time is the same as the fixed dust removal mode time.

[0044] 5) Set the temperature difference threshold for the number of fan groups to be activated in the cooling mode. This is used to determine whether to activate 1 or 2 fan groups. The default threshold is 10℃. Temperature difference = air outlet temperature - air inlet temperature.

[0045] 6) Select the desired dust removal mode. There are three dust removal modes: First, fixed dust removal mode, where the dust removal module starts after each run of the flexible charging pile; second, temperature-controlled dust removal mode, where the dust removal mode is activated based on the temperature difference between the inlet and outlet air after the flexible charging pile has finished running; and third, condition-based dust removal mode, where the dust removal mode is activated only if the flexible charging pile runs for a set duration. These three dust removal modes adapt to different operating conditions, allowing for efficient energy saving by switching between modes according to the environment in which the flexible charging pile is used.

[0046] After determining the operating parameters, the flexible charging pile's heat dissipation control high and low level signals are collected by the flexible charging pile working status signal acquisition module. A high level indicates that the flexible charging pile is in standby mode, and a low level indicates that it is in working mode. A level change is required for the initial power-on operation to activate the logic operation. Without a level change, the device will remain in standby mode and will not perform any action. With a level change, it will proceed to the next process based on the result.

[0047] When the flexible charging pile working status signal acquisition module detects that the flexible charging pile has switched to the running state, the device controls the AC bidirectional axial flow fan through the fan bidirectional control module to carry out heat dissipation work, ensuring the normal operation of the flexible charging pile. In the heat dissipation mode, the device judges the temperature difference between the inlet and outlet to control the number of fans to be put into operation. When the temperature difference is ≤10℃, only the first set of fans is put into operation. When the temperature difference is >10℃, two sets of fans are put into operation to achieve the purpose of energy saving and noise reduction.

[0048] When the flexible charging pile working status signal acquisition module detects that the flexible charging pile has switched from running to standby, the device first waits for 60 seconds according to the set AC bidirectional axial flow fan reversal interval, and then performs condition judgment according to the set dust removal mode. In the fixed dust removal mode, it will run for 3 minutes to remove dust. In the temperature control dust removal mode, it first judges whether the temperature difference when the flexible charging pile stops meets the requirements. If the requirements are met, it starts dust removal until the temperature difference between the inlet and outlet is ≤1℃ and then stops. In the working condition dust removal mode, it first judges whether the current running time of the flexible charging pile is ≥10 minutes. If the conditions are met, it runs for 3 minutes to remove dust. After the dust removal step is completed, the device switches to standby mode.

[0049] When the dust removal mode is running, and the flexible charging pile operating status signal acquisition module detects that the flexible charging pile has switched from standby to operation, the device immediately stops the dust removal mode, waits for 60 seconds according to the set AC bidirectional axial fan commutation interval, and then starts the heat dissipation mode to ensure the normal operation of the flexible charging pile. This process repeats cyclically based on the flexible charging pile status signal conditions.

[0050] This embodiment enables automatic dust removal after each operation of the flexible charging pile. The residual heat of the rectifier module inside the flexible charging pile dries the damp dust and willow catkins adsorbed by the air inlet and blows them away from the filter screen, reducing the accumulation of dust and willow catkins, reducing the impact on equipment heat dissipation, and extending the service life and efficiency of the equipment.

[0051] Example 2

[0052] Embodiment 2 of the present invention introduces an automatic dust removal control device for flexible charging piles.

[0053] The automatic dust removal control device for the flexible charging pile in this embodiment can be an independent add-on module installed on the existing flexible charging pile, or it can be integrated into the flexible charging pile during the design and production stage as its own function, and work with the AC bidirectional axial flow fan to achieve the function.

[0054] like Figure 3 The automatic dust removal control device for a flexible charging pile, as shown, includes a main control module, a flexible charging pile operating status signal acquisition module, a temperature acquisition module, a DIP switch module, a bidirectional fan control module, and a power supply module. Specifically, the main control module processes the acquired status and temperature signals and controls other modules to cooperate in achieving the dust removal function according to a preset program. The flexible charging pile operating status signal acquisition module acquires the level signal of the flexible charging pile's heat dissipation control interface and judges the operating status of the flexible charging pile by the changes in high and low level signals. The temperature acquisition module acquires the temperature at the inlet and outlet of the air and uses it to calculate the temperature difference, which is used in conjunction with the program logic of the main control module. The DIP switch module mainly performs parameter setting functions and consists of 8 DIP switches to set the operating parameters and select the operating mode for the dust removal mode and heat dissipation mode. The bidirectional fan control module can control the AC bidirectional axial flow fan to change the airflow direction to achieve the purpose of heat dissipation and dust removal mode switching. It can also control the fans in groups according to the outlet temperature, which has the effect of energy saving and noise reduction. The power supply module provides operating power for the above modules.

[0055] In this embodiment, the automatic dust removal control device for the flexible charging pile first calls the flexible charging pile operating status signal acquisition module to collect the heat dissipation control signal of the flexible charging pile, determines the operating status of the flexible charging pile, and decides whether to enter the heat dissipation mode or the dust removal mode. The temperature acquisition module collects the temperature difference between the inlet and outlet of the flexible charging pile's heat dissipation air duct to determine the dust removal duration in the temperature-controlled dust removal mode and the number of fan groups to be activated in the heat dissipation mode. When the flexible charging pile operating status signal acquisition module determines that the flexible charging pile has changed from the working state to the standby state, the fan bidirectional control module controls the AC bidirectional axial flow fan to change the airflow direction to air intake at the outlet and air outlet at the inlet. The residual heat of the rectifier module inside the flexible charging pile dries the willow catkins and dust adsorbed on the air intake filter and blows them away from the filter, achieving the purpose of automatic dust removal for the flexible charging pile. When the flexible charging pile operating status signal acquisition module detects that the flexible charging pile has changed from the standby state to the working state in the dust removal working state, it immediately stops the dust removal and switches the working state to the heat dissipation working state according to the interval set by the DIP switch module to ensure the operation of the flexible charging pile.

[0056] The detailed steps of the automatic dust removal control device for flexible charging piles are the same as those of the automatic dust removal control method for flexible charging piles provided in Example 1, and will not be repeated here.

[0057] The above description is merely a preferred embodiment of this practice and is not intended to limit the scope of this practice. Various modifications and variations can be made to this practice by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this practice should be included within the protection scope of this practice.
