[0002] The charging and swapping cabinet for two- and three-wheeled electric vehicles is a distributed shared device, which needs to be remotely connected to the Internet through the wireless communication unit (cellular data, such as 4G traffic card) on the cabinet body, and the terminal needs to interact with the platform / mobile terminal to complete the battery swap logic. However, due to hardware failure, unstable signal and other factors, the wireless communication module on the cabinet body may occasionally be unable to connect to the Internet. At this time, the user will not be able to swap batteries through the wireless communication unit on the cabinet body.

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0033] Figure 1 It is a flow chart of a data transmission method for a power exchange cabinet in a local area network provided by an embodiment of the present invention;

[0034] Figure 2 It is a principle block diagram of the local area networked power exchange cabinet data transmission system provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0035] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0036] refer to Figure 1 , which is a flow chart of an optional embodiment of the local area networking power exchange cabinet data transmission method provided by the present invention.

[0037] The power exchange cabinet data transmission method forms a local area network by connecting multiple power exchange cabinets within a preset distance range, so that when any of the multiple power exchange cabinets has a network abnormality, data transmission continues to be carried out between the other power exchange cabinets with normal networks and the cloud platform, thereby ensuring normal data transmission. Moreover, in the embodiment of the present invention, each power exchange cabinet is provided with an independent wireless communication module (cellular mobile data module, such as 4G, etc.), and it is a low probability event that these wireless communication modules are disconnected from the network at the same time. Therefore, the online reliability can be greatly increased, and the normal progress of the power exchange process can be ensured.

[0038] Specifically, the local area networked power exchange cabinet data transmission method can be applied to a power exchange cabinet system, wherein the power exchange cabinet system of an embodiment of the present invention includes: multiple power exchange cabinets. Furthermore, in an embodiment of the present invention, the distance between the multiple power exchange cabinets is within a preset distance range. Optionally, the preset distance range is within 10 meters.

[0039] like Figure 1 As shown, the data transmission method of the power exchange cabinet in the local area network includes:

[0040] Step S1. During operation or battery replacement, multiple battery swap cabinets detect their own networking status in real time and determine whether the conditions for data transmission are met; if so, execute step S2; if not, execute step S3.

[0041] Optionally, before step S1, the method includes: multiple power exchange cabinets are locally networked by wired or wireless means. That is, after multiple power exchange cabinets within a preset distance are installed, local network can be formed, wherein the local network can be in the form of wired or wireless networking.

[0042] In some embodiments, multiple power exchange cabinets are locally networked through wired means, including: multiple power exchange cabinets are locally networked through any one of network cable connection, serial port communication connection, and CAN communication connection.

[0043] Alternatively, in some other embodiments, multiple power exchange cabinets are locally networked by wireless means, including: multiple power exchange cabinets are locally networked by WIFI connection or Bluetooth connection.

[0044] In an embodiment of the present invention, after completing the local area networking, multiple power exchange cabinets can use the form of primary and secondary power exchange cabinets to detect and judge their respective networking status, or they can use the form of no distinction between primary and secondary power exchange cabinets to detect and judge the networking status.

[0045] In some embodiments, the multiple power-swapping cabinets include: a main power-swapping cabinet and multiple sub-power-swapping cabinets. During operation or power-swapping, the multiple power-swapping cabinets detect their own networking status in real time and determine whether the conditions for data transmission are met, including: the main power-swapping cabinet detects its own networking status in real time, and sends networking status detection instructions to the multiple sub-power-swapping cabinets in real time; the multiple sub-power-swapping cabinets detect their own networking status in real time, and send status detection results to the main power-swapping cabinet according to the networking status detection instructions; the main power-swapping cabinet determines whether itself and the multiple sub-power-swapping cabinets meet the conditions for data transmission based on its own networking status and the status detection results sent by the multiple sub-power-swapping cabinets. Furthermore, the multiple sub-power-swapping cabinets exchange their respective status detection results in real time, and determine whether each meets the conditions for data transmission based on their respective status detection results.

[0046] In this embodiment, multiple power exchange cabinets are used in the form of main and secondary power exchange cabinets for networking status detection and judgment. Specifically, any one of the multiple power exchange cabinets is set as the main power exchange cabinet, and the rest are set as sub-power exchange cabinets. When performing network status detection, the main power exchange cabinet detects its own networking status in real time, and sends networking status detection instructions to multiple sub-power exchange cabinets in real time. Multiple sub-power exchange cabinets detect their own networking status in real time, and return their own status detection results to the main power exchange cabinet at regular intervals. The main power exchange cabinet judges the transmission data conditions based on its own networking status and the status detection results returned by the multiple sub-power exchange cabinets, thereby determining the transmission data conditions of each sub-power exchange cabinet and the main power exchange cabinet, and sending its own transmission data conditions and the transmission data conditions of each sub-power exchange cabinet to each sub-power exchange cabinet in real time. It should be noted that in this embodiment, each sub-power exchange cabinet can also communicate with each other, so that when the network of any power exchange cabinet is abnormal, data can be transmitted through other power exchange cabinets.

[0047] Alternatively, in some other embodiments, multiple power-swap cabinets detect their own networking status in real time and determine whether the data transmission conditions are met during operation or power-swap process, including: multiple power-swap cabinets detect their own networking status in real time, and determine whether each meets the data transmission conditions based on their respective status detection results. That is, multiple power-swap cabinets within a preset distance range detect their own networking status in real time and determine whether they meet the data transmission conditions, and can obtain the real-time data transmission conditions of other power-swap cabinets, so that when the network of any power-swap cabinet is abnormal, data can be transmitted through other power-swap cabinets.

[0048] Step S2: The battery swap cabinet that meets the data transmission conditions maintains data transmission between the battery swap cabinet and the cloud platform.

[0049] Step S3, the battery swap cabinet that does not meet the data transmission conditions completes the data transmission between the battery swap cabinet that does not meet the data transmission conditions and the cloud platform through a designated battery swap cabinet among the battery swap cabinets that meet the data transmission conditions.

[0050] Optionally, in an embodiment of the present invention, the designated power swap cabinet is the power swap cabinet with the strongest signal transmission among the power swap cabinets that meet the data transmission conditions.

[0051] There are four power swap cabinets A, B, C, and D within the preset distance range. After the installation is completed, the four power swap cabinets can complete local area networking through wired or wireless means (of course, local area networking can also be performed in real time during work or power swapping). After completing the local area networking, during work or power swapping, each power swap cabinet detects its own networking status in real time and determines its own data transmission conditions (that is, whether it can connect to the cloud platform. If it can connect to the cloud platform, it is determined that the data transmission conditions are met. If the network is disconnected from the cloud platform, it is determined that the data transmission conditions are not met), and feeds back its own data transmission conditions to other power swap cabinets. Therefore, when any of A, B, C, and D has a network failure, data interaction with the cloud platform can be carried out through the other cabinets. For example, during the battery swapping process, battery swap cabinet A encounters a network anomaly and cannot interact with the cloud platform normally. At this time, battery swap cabinet A selects the one with the strongest transmission signal from the three battery swap cabinets B, C, and D (set as battery swap cabinet C). Then battery swap cabinet C is the designated battery swap cabinet, and the data transmission of battery swap cabinet A is completed through battery swap cabinet C. That is, battery swap cabinet A transmits data to battery swap cabinet C, which then transmits it to the cloud platform. After the cloud platform performs relevant data processing, it returns the data to battery swap cabinet C, which is then transmitted back to battery swap cabinet A. In this way, when the network of battery swap cabinet A is abnormal, the data interaction with the cloud platform is continued through battery swap cabinet C, ensuring the reliability and continuity of the data transmission of battery swap cabinet A.

[0052] Furthermore, in an embodiment of the present invention, the power swap cabinet data includes: equipment data of the power swap cabinet and information data during the power swap process.

[0053] The equipment data of the battery swap cabinet includes any one or more of hardware information data, alarm data, flow data and maintenance data. The hardware information data includes any one or more of the charger data of the battery swap cabinet, the battery power data of the battery swap cabinet and the cell voltage data of the battery swap cabinet.

[0054] Furthermore, in some embodiments, the local area networked power swap cabinet data transmission method also includes: the cloud platform sends remote control instructions to the power swap cabinets that do not meet the data transmission conditions through a designated power swap cabinet among the power swap cabinets that meet the data transmission conditions.

[0055] Specifically, when any of the multiple power swap cabinets within a preset distance range has a network abnormality and cannot communicate and exchange data normally with the cloud platform, the communication and data exchange between the abnormal power swap cabinet and the cloud platform can be continued through any power swap cabinet with normal network in the networking, so as to ensure that the equipment data of the power swap cabinet continues to be uploaded to the cloud platform, so that when the network of the power swap cabinet is abnormal, the cloud platform can also realize normal monitoring of the power swap cabinet, and avoid the inability to monitor the real-time status of the power swap cabinet due to network abnormality. For example, when the battery cell voltage of the power swap cabinet is abnormal and the temperature rises rapidly, the alarm data cannot be uploaded to the cloud platform due to the network abnormality of the power swap cabinet. At this time, the alarm data can be uploaded to the cloud platform through other power swap cabinets with normal network. After receiving the alarm data, the cloud platform can send back the control instruction to stop working to the power swap cabinet with abnormal network through the power swap cabinet with normal network, so as to control the power swap cabinet with abnormal network to stop working in time and avoid accidents. Alternatively, the cloud platform can also notify the nearest operation and maintenance personnel to go to the site for investigation and repair in time according to the alarm data.

[0056] The local area networked power exchange cabinet data transmission method of the present invention can realize data breakpoint-free and seamless transmission without adding any additional communication modules by locally networking multiple power exchange cabinets within a preset distance. It is simple to implement, low cost, good online reliability, and stable and reliable data transmission. In addition, when the power exchange cabinet network is abnormal, real-time status monitoring and control of the power exchange cabinet can still be achieved.

[0057] refer to Figure 2 , which is a principle block diagram of an optional embodiment of the local area networking power exchange cabinet data transmission system provided by the present invention.

[0058] The local area networked power exchange cabinet data transmission system can be used to implement the local area networked power exchange cabinet data transmission method disclosed in the embodiment of the present invention.

[0059] Specifically, Figure 2 As shown, the local area networked battery swap cabinet data transmission system includes: a battery swap cabinet system and a cloud platform.

[0060] The power exchange cabinet system includes: multiple power exchange cabinets, and the distance between the multiple power exchange cabinets is within a preset distance range. The power exchange cabinet system and the cloud platform exchange data through the power exchange cabinet data transmission method of the local area network disclosed in the embodiment of the present invention. Figure 2 As shown, a total of n power exchange cabinets, namely #1 power exchange cabinet, #2 power exchange cabinet, ..., #n power exchange cabinet, can be set within a preset distance range, among which the n power exchange cabinets can exchange data with each other after local area networking.

[0061] Optionally, the preset distance range is within 10 meters.

[0062] The multiple power exchange cabinets are locally networked by wired or wireless means. That is, after multiple power exchange cabinets within a preset distance are installed, local networking can be performed, wherein the local networking can be in the form of wired networking or wireless networking.

[0063] In some embodiments, multiple power exchange cabinets are locally networked through wired means, including: multiple power exchange cabinets are locally networked through any one of network cable connection, serial port communication connection, and CAN communication connection.

[0064] Alternatively, in some other embodiments, multiple power exchange cabinets are locally networked by wireless means, including: multiple power exchange cabinets are locally networked by WIFI connection or Bluetooth connection.

[0065] In an embodiment of the present invention, after completing the local area networking, multiple power exchange cabinets can use the form of primary and secondary power exchange cabinets to detect and judge their respective networking status, or they can use the form of no distinction between primary and secondary power exchange cabinets to detect and judge the networking status.

[0066] In some embodiments, the multiple power-swapping cabinets include: a main power-swapping cabinet and multiple sub-power-swapping cabinets. During operation or power-swapping, the multiple power-swapping cabinets detect their own networking status in real time and determine whether the conditions for data transmission are met, including: the main power-swapping cabinet detects its own networking status in real time, and sends networking status detection instructions to the multiple sub-power-swapping cabinets in real time; the multiple sub-power-swapping cabinets detect their own networking status in real time, and send status detection results to the main power-swapping cabinet according to the networking status detection instructions; the main power-swapping cabinet determines whether itself and the multiple sub-power-swapping cabinets meet the conditions for data transmission based on its own networking status and the status detection results sent by the multiple sub-power-swapping cabinets. Furthermore, the multiple sub-power-swapping cabinets exchange their respective status detection results in real time, and determine whether each meets the conditions for data transmission based on their respective status detection results.

[0067] In this embodiment, multiple power exchange cabinets are used in the form of main and secondary power exchange cabinets for networking status detection and judgment. Specifically, any one of the multiple power exchange cabinets is set as the main power exchange cabinet, and the rest are set as sub-power exchange cabinets. When performing network status detection, the main power exchange cabinet detects its own networking status in real time, and sends networking status detection instructions to multiple sub-power exchange cabinets in real time. Multiple sub-power exchange cabinets detect their own networking status in real time, and return their own status detection results to the main power exchange cabinet at regular intervals. The main power exchange cabinet judges the transmission data conditions based on its own networking status and the status detection results returned by the multiple sub-power exchange cabinets, thereby determining the transmission data conditions of each sub-power exchange cabinet and the main power exchange cabinet, and sending its own transmission data conditions and the transmission data conditions of each sub-power exchange cabinet to each sub-power exchange cabinet in real time. It should be noted that in this embodiment, each sub-power exchange cabinet can also communicate with each other, so that when the network of any power exchange cabinet is abnormal, data can be transmitted through other power exchange cabinets.

[0068] Alternatively, in some other embodiments, multiple power-swap cabinets detect their own networking status in real time and determine whether the data transmission conditions are met during operation or power-swap process, including: multiple power-swap cabinets detect their own networking status in real time, and determine whether each meets the data transmission conditions based on their respective status detection results. That is, multiple power-swap cabinets within a preset distance range detect their own networking status in real time and determine whether they meet the data transmission conditions, and can obtain the real-time data transmission conditions of other power-swap cabinets, so that when the network of any power-swap cabinet is abnormal, data can be transmitted through other power-swap cabinets.

[0069] Optionally, in an embodiment of the present invention, the designated power swap cabinet is the power swap cabinet with the strongest signal transmission among the power swap cabinets that meet the data transmission conditions.

[0070] There are four power swap cabinets A, B, C, and D within the preset distance range. After the installation is completed, the four power swap cabinets can complete local area networking through wired or wireless means (of course, local area networking can also be performed in real time during work or power swapping). After completing the local area networking, during work or power swapping, each power swap cabinet detects its own networking status in real time and determines its own data transmission conditions (that is, whether it can connect to the cloud platform. If it can connect to the cloud platform, it is determined that the data transmission conditions are met. If the network is disconnected from the cloud platform, it is determined that the data transmission conditions are not met), and feeds back its own data transmission conditions to other power swap cabinets. Therefore, when any of A, B, C, and D has a network failure, data interaction with the cloud platform can be carried out through the other cabinets. For example, during the battery swapping process, battery swap cabinet A encounters a network anomaly and cannot interact with the cloud platform normally. At this time, battery swap cabinet A selects the one with the strongest transmission signal from the three battery swap cabinets B, C, and D (set as battery swap cabinet C). Then battery swap cabinet C is the designated battery swap cabinet, and the data transmission of battery swap cabinet A is completed through battery swap cabinet C. That is, battery swap cabinet A transmits data to battery swap cabinet C, which then transmits it to the cloud platform. After the cloud platform performs relevant data processing, it returns the data to battery swap cabinet C, which is then transmitted back to battery swap cabinet A. In this way, when the network of battery swap cabinet A is abnormal, the data interaction with the cloud platform is continued through battery swap cabinet C, ensuring the reliability and continuity of the data transmission of battery swap cabinet A.

[0071] Furthermore, in an embodiment of the present invention, the power swap cabinet data includes: equipment data of the power swap cabinet and information data during the power swap process.

[0072] The equipment data of the battery swap cabinet includes any one or more of hardware information data, alarm data, flow data and maintenance data. The hardware information data includes any one or more of the charger data of the battery swap cabinet, the battery power data of the battery swap cabinet and the cell voltage data of the battery swap cabinet.

[0073] Furthermore, in some embodiments, the cloud platform can also issue remote control instructions to the power swap cabinet that does not meet the transmission conditions through the designated power swap cabinet in the power swap cabinet that meets the data transmission conditions, so as to achieve remote control of the power swap cabinet with network abnormality or failure when the power swap cabinet network is abnormal or faulty.

[0074] Specifically, when any of the multiple power swap cabinets within a preset distance range has a network abnormality and cannot communicate and exchange data normally with the cloud platform, the communication and data exchange between the abnormal power swap cabinet and the cloud platform can be continued through any power swap cabinet with normal network in the networking, so as to ensure that the equipment data of the power swap cabinet continues to be uploaded to the cloud platform, so that when the network of the power swap cabinet is abnormal, the cloud platform can also realize normal monitoring of the power swap cabinet, and avoid the inability to monitor the real-time status of the power swap cabinet due to network abnormality. For example, when the battery cell voltage of the power swap cabinet is abnormal and the temperature rises rapidly, the alarm data cannot be uploaded to the cloud platform due to the network abnormality of the power swap cabinet. At this time, the alarm data can be uploaded to the cloud platform through other power swap cabinets with normal network. After receiving the alarm data, the cloud platform can send back the control instruction to stop working to the power swap cabinet with abnormal network through the power swap cabinet with normal network, so as to control the power swap cabinet with abnormal network to stop working in time and avoid accidents. Alternatively, the cloud platform can also notify the nearest operation and maintenance personnel to go to the site for investigation and repair in time according to the alarm data.

[0075] The local area networked power exchange cabinet data transmission system of the present invention can realize data breakpoint-free and seamless transmission without adding any additional communication modules by locally networking multiple power exchange cabinets within a preset distance range. It is simple to implement, low cost, good online reliability, and stable and reliable data transmission. In addition, when the power exchange cabinet network is abnormal, real-time status monitoring and control of the power exchange cabinet can still be achieved.
