Description

Technical Field

[0001] Example embodiments of the present disclosure generally relate to monitoring of wiring harnesses of solar panels, and more particularly to systems and methods for monitoring connection status of wiring harnesses of solar panels, riding tools, and computer-readable storage media. Background Art

[0002] With the mass operation of shared bicycles, solar panels have become the core component for vehicles to obtain energy. However, in the current manual assembly process of the whole vehicle, it is inevitable that the wiring harness of the solar panel will be poorly connected. Once the wiring harness of the solar panel is poorly connected, the whole vehicle will not be able to replenish power, so that the vehicle will frequently enter a low-power state during road operation, seriously affecting the vehicle's operating efficiency. Conventional solar panel plug-in fault detection is to determine whether the wiring harness connection is normal by detecting whether the solar panel has voltage output. However, this detection method is heavily dependent on lighting conditions, and solar panels cannot perform fault detection under no lighting conditions. In addition, this detection method generally requires the vehicle to be returned to the warehouse to meet the detection conditions, and the detection cost is high and the process is complicated. In addition, this detection method cannot automatically identify the wiring harness connection failure of the solar panel and cannot automatically report the fault. Summary of the invention

[0032] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0034] As briefly mentioned above, conventional solar panel plug-in fault detection determines whether the wiring harness connection is normal by detecting whether the solar panel has voltage output. However, this detection method is heavily dependent on lighting conditions, and solar panels cannot perform fault detection under no lighting conditions. In addition, this detection method generally requires the vehicle to be returned to the warehouse to meet the detection conditions, which has high detection costs and complicated processes. In addition, this detection method cannot automatically identify solar panel wiring harness connection faults and cannot automatically report faults.

[0035] To this end, an embodiment of the present disclosure proposes a scheme for monitoring the connection status of the wiring harness of a solar panel. According to various embodiments of the present disclosure, in addition to the traditional charging harness and grounding harness, a detection harness is additionally added to the solar panel. The detection harness is connected to the charging harness on the solar panel side, and voltage can be injected into the charging harness via a switch device. With this arrangement, when the solar panel is exposed to light, it can be determined whether the wiring harness connection is faulty based on whether the voltages of the charging harness and the detection harness are consistent. When the solar panel is not exposed to light, the switch device can be turned on to inject voltage into the detection harness, and then by detecting whether the voltages of the charging harness and the detection harness are consistent, it can be determined whether the wiring harness connection is faulty.

[0036] It will be understood from the following description that according to the embodiments of the present disclosure, the detection of the wiring harness connection status of the solar panel can be completed anytime and anywhere, no longer relying on the lighting conditions, and the detection can be performed without returning the vehicle to the warehouse, with low detection costs and simple processes. In addition, this detection method can automatically identify the wiring harness connection fault of the solar panel, and automatically report the fault to the service end and issue a work order for inspection and repair.

[0037] Some example embodiments of the present disclosure will be described below with reference to the accompanying drawings. Please note that in some descriptions of the embodiments, certain specific values ​​may be involved in order to better help readers understand. These values ​​are exemplary and may vary according to specific application scenarios, and do not limit the scope of the present disclosure in any way.

[0038] Figure 1 Schematic diagram of an example environment in which embodiments of the present disclosure can be implemented. Figure 1 As shown, the solar panel 10 can charge the battery 30 via the charging unit 20. The solar panel 10, the charging unit 20 and the battery 30 can be arranged on a riding tool such as a shared bicycle. In the following, the principle of the present disclosure will be explained using a shared bicycle as an application scenario. However, it should be understood that the solar panel 10, the charging unit 20 and the battery 30 can also be arranged in other application scenarios, and the embodiments of the present disclosure are not limited to this. The wiring harness on the solar panel 10 can be plugged together with the wiring harness on the charging unit 20 through a connector. However, during the manual assembly process of the shared bicycle, it is inevitable that the wiring harness of the solar panel 10 and the wiring harness of the charging unit 20 will be poorly plugged in, which will cause the entire vehicle to be unable to be recharged, so that the vehicle will frequently enter a low-power state during road operation, seriously affecting the vehicle's operating efficiency.

[0039] Figure 2 FIG. 1 is a schematic diagram of a system for monitoring the wiring harness connection status of a solar panel (also referred to as a wiring harness status monitoring system) according to some embodiments of the present disclosure. Figure 2As shown, the system described herein can be set on a riding tool such as a shared bicycle, and generally includes a solar panel 10, a charging unit 20, a processing unit 40 and a switching device 50. The solar panel 10 can charge the battery 30 via the charging unit 20. The charging unit 20 may include a charging chip or any other suitable type of charging control unit for charging control of the battery 30. The battery 30 may include a lithium battery or any other suitable type of battery. A first charging harness 110, a first detection harness 120 and a first ground harness 130 are provided on the solar panel 10. The first ground harness 130 is used to provide a voltage reference. The first charging harness 110 is used to output a charging voltage. The first charging harness 110 is connected to the first detection harness 120 on the solar panel 10, that is, short-circuited, so that they can be at the same voltage. The first detection harness 120 is provided to facilitate the detection of the connection state of the first charging harness 110, so as to promptly discover the plug-in fault of the first charging harness 110. The processing unit 40 may include a microcontroller unit (MCU) or any other type of processing unit.

[0040] like Figure 2 As shown, the charging unit 20 is electrically connected to the second charging harness 210 and the second ground harness 230. The second charging harness 210 can be plugged into the first charging harness 110 via the plug 610, thereby providing the charging voltage to the charging unit 20. The second ground harness 230 can be plugged into the first ground harness 130 via the plug 630 to provide a voltage reference to the charging unit 20. The second detection harness 220 can be plugged into the first detection harness 120 via the plug 620, and the switch device 50 is electrically connected to the second detection harness 220. When the switch device 50 is turned on, a predetermined voltage can be applied to the second detection harness 220 via the switch device 50. The predetermined voltage can be the voltage Vbat provided by the battery 30 or any other appropriate level of voltage. The on-off state of the switch device 50 can be controlled by the processing unit 40 via the general input and output interface GPIO1. The switch device 50 may include a metal oxide semiconductor field effect transistor (MOSFET), an insulated gate bipolar transistor (IGBT), or any other appropriate type of switch device.

[0041] When the solar panel 10 is exposed to light, the processing unit 40 can determine whether the wiring harness connection of the solar panel 10 is faulty according to whether the charging wiring harness voltage Vbus on the second charging wiring harness 210 is consistent with the detection wiring harness voltage Vsense on the second detection wiring harness 220. When the solar panel 10 is not exposed to light, the switch device 50 can be turned on to inject a predetermined voltage into the second detection wiring harness 220, and then the processing unit 40 can determine whether the wiring harness connection of the solar panel 10 is faulty by detecting whether the charging wiring harness voltage Vbus is consistent with the detection wiring harness voltage Vsense.

[0042] In order to monitor the wiring harness connection status of the solar panel 100, the processing unit 40 can collect the charging harness voltage Vbus on the second charging harness 210 and the detection harness voltage Vsense on the second detection harness 220. In one embodiment, the processing unit 40 can collect the voltages Vbus and Vsense through an analog-to-digital conversion unit (ADC). For example, the processing unit 40 can receive the voltage Vbus via pin ADC1 to collect the voltage Vbus through the corresponding analog-to-digital conversion unit. The processing unit 40 can receive the voltage Vsense via pin ADC2 to collect the voltage Vsense through the corresponding analog-to-digital conversion unit. In addition, the processing unit 40 can receive a voltage reference via pin GNS. When the charging harness voltage Vbus and the detection harness voltage Vsense are collected, the processing unit 40 can determine at least one of the connection states between the first charging harness 110 and the second charging harness 210 and the connection state between the first detection harness 120 and the second detection harness 220 based on the voltages Vbus and Vsense. Next, we will combine Figure 3 An example process 300 performed by processing unit 40 is described below.

[0043] like Figure 3 As shown, process 300 begins at block 301 .

[0044] In block 310 , the system is powered on, and the battery 30 supplies power to the processing unit 40 . The processing unit 40 can continuously collect the charging harness voltage Vbus on the second charging harness 210 and the detection harness voltage Vsense on the second detection harness 220 .

[0045] In box 3201, the processing unit 40 can determine whether the charging harness voltage Vbus is higher than the voltage threshold Vth. In response to the charging harness voltage Vbus being higher than the voltage threshold Vth, the process 300 can proceed to box 3202. In response to the charging harness voltage Vbus being lower than the voltage threshold Vth, the process 300 can proceed to box 3206. The voltage threshold Vth described herein is set to be lower than or equal to a predetermined voltage injected into the second detection harness 220 when the switching device 50 is turned on. In response to the charging harness voltage Vbus being equal to the voltage threshold Vth, the process 300 can proceed to box 3202 or box 3206, which can be set according to design requirements.

[0046] In some embodiments, in response to the charging harness voltage Vbus being higher than the voltage threshold Vth, the processing unit 40 may determine that the connection between the first charging harness 110 and the second charging harness 210 is normal.

[0047] In some embodiments, in response to the charging harness voltage Vbus being higher than the voltage threshold Vth, the processing unit 40 may determine that the solar panel 10 is able to receive light.

[0048] In block 3202, the processing unit 40 may determine whether the charging harness voltage Vbus is equal to the detection harness voltage Vsense. In response to the charging harness voltage Vbus being equal to the detection harness voltage Vsense, the process 300 may proceed to block 3203. In response to the charging harness voltage Vbus being unequal to the detection harness voltage Vsense, the process 300 may proceed to block 3204.

[0049] In block 3203, in response to the charging harness voltage Vbus being equal to the detection harness voltage Vsense, the processing unit 40 may determine that the connection between the first detection harness 120 and the second detection harness 220 is also normal. In other words, in response to the charging harness voltage Vbus being higher than the voltage threshold and the charging harness voltage Vbus being equal to the detection harness voltage Vsense, the processing unit 40 may determine that the connection between the first charging harness 110 and the second charging harness 210 and the connection between the first detection harness 120 and the second detection harness 220 are both normal. Then, the process 300 may return to block 310.

[0050] In block 3204 , in response to the charging harness voltage Vbus being unequal to the detection harness voltage Vsense, the processing unit 40 may determine that the connection between the first detection harness 120 and the second detection harness 220 is abnormal. Then, the process 300 may proceed to block 3205 .

[0051] In block 3205, when the connection between the first detection harness 120 and the second detection harness 220 is abnormal, the processing unit 40 may send the connection status between the first detection harness 120 and the second detection harness 220 to the server to report the abnormal connection, i.e., the connection failure, to the server. The server may issue a work order for maintenance. Then, the process may end in block 302.

[0052] In block 3206, the processing unit 40 may determine whether the detection harness voltage Vsense is higher than the voltage threshold Vth. In response to the detection harness voltage Vsense being higher than the voltage threshold Vth, the process 300 may proceed to block 3207. In response to the detection harness voltage Vsense being lower than the voltage threshold Vth, the process 300 may proceed to block 3208. In response to the detection harness voltage Vsense being equal to the voltage threshold Vth, the process 300 may proceed to block 3207 or block 3208, which may be set according to design requirements.

[0053] In block 3207, in response to the detection harness voltage Vsense being higher than the voltage threshold Vth, the processing unit 40 may determine that the connection between the first charging harness 110 and the second charging harness 210 is abnormal. In other words, in response to the charging harness voltage Vbus being lower than the voltage threshold Vth and the detection harness voltage Vsense being higher than the voltage threshold Vth, the processing unit 40 may determine that the connection between the first detection harness 120 and the second detection harness 220 is normal, while the connection between the first charging harness 110 and the second charging harness 210 is abnormal. Then, the process 300 may proceed to block 3205 to send the connection status between the first charging harness 110 and the second charging harness 210 to the service end, so as to report the connection abnormality, i.e., the connection failure, to the service end.

[0054] In some embodiments, in response to the charging harness voltage Vbus being lower than the voltage threshold Vth and the sensing harness voltage Vsense being higher than the voltage threshold Vth, the processing unit 40 may determine that the solar panel 10 is able to receive light.

[0055] In block 3208, in response to the detection harness voltage Vsense being lower than the voltage threshold Vth, the processing unit 40 may turn on the switch device 50 to apply a predetermined voltage to the second detection harness 220. In other words, in response to both the charging harness voltage Vbus and the detection harness voltage Vsense being lower than the voltage threshold Vth, the processing unit 40 may turn on the switch device 50.

[0056] At block 3209, the processing unit 40 may determine whether the charging harness voltage Vbus is equal to the detection harness voltage Vsense. In response to the charging harness voltage Vbus being unequal to the detection harness voltage Vsense, the process 300 may proceed to block 3210. In response to the charging harness voltage Vbus being equal to the detection harness voltage Vsense, the process 300 may proceed to block 3211.

[0057] In block 3210, in response to the charging harness voltage Vbus being unequal to the detection harness voltage Vsense, the processing unit 40 may determine that the connection between the first detection harness 120 and the second detection harness 220 and / or the connection between the first charging harness 110 and the second charging harness 210 is abnormal. Then, the process 300 may proceed to block 3205 to send the connection status between the first detection harness 120 and the second detection harness 220 and / or the connection status between the first charging harness 110 and the second charging harness 210 to the service end, so as to report the connection abnormality, i.e., the connection failure, to the service end.

[0058] In block 3211, in response to the charging harness voltage Vbus being equal to the detection harness voltage Vsense, the processing unit 40 may determine that the connection between the first charging harness 110 and the second charging harness 210 and the connection between the first detection harness 120 and the second detection harness 220 are both normal. Then, the process 300 may return to block 310.
