These sensors can provide feedback signals or drive signals to drive the motor to operate accurately when the mechanical structure of the battery swap station moves. They are indispensable control auxiliary equipment for the normal operation of the battery swap station.

[0030] In the related art, wiring harnesses are often used to connect sensors to devices such as repeaters. However, when a battery swap station includes a large number of sensors, a large number of wiring harnesses are required. The wiring harnesses are long and the wiring layout is complex. The installation and layout of the battery swap station is time-consuming and expensive.

[0031] In order to solve the problem that when a battery swap station includes many sensors, a large number of wiring harnesses are required, the wiring harnesses are long and the line layout is complex, and the installation and layout of the battery swap station takes a long time and is expensive, the present application provides a wireless hub device and a battery swap station.

[0032] In a first aspect, the present application provides a wireless hub device.

[0033] The wireless hub device provided by this application is applied to a target device, which includes a repeater and multiple sensors 1, combined with Figure 1 As shown, the wireless hub device provided in this application includes an acquisition circuit 100 and a wireless communication module 200 .

[0034] The acquisition circuit 100 is connected to a plurality of sensors 1 .

[0035] The wireless communication module 200 is connected to the acquisition circuit 100 .

[0036] The acquisition circuit 100 can acquire the analog signal of the sensor 1 and send the analog signal to the wireless communication module 200. The wireless communication module 200 can process the analog signal and send the processed analog signal to the repeater.

[0037] Under the premise of adopting the above technical solution, the wireless line collection device provided by this application is connected to multiple sensors 1 through the acquisition circuit 100, which can concentrate the sensor 1 wiring harness and collect analog signals from multiple sensors 1; the wireless communication module 200 can process the analog signal and send the processed analog signal to the repeater, realizing wireless communication between the wireless collection device and the repeater. In this way, this application replaces the wiring harness between the sensor 1 and the repeater in the related art through wireless communication, which is conducive to reducing the length and number of wiring harnesses, simplifying the wiring layout of the battery swap station, and helping to reduce the construction cost and maintenance cost of the battery swap station.

[0038] Regarding the acquisition circuit 100 .

[0039] In some embodiments, combined Figure 1 As shown, the acquisition circuit 100 includes a connector 101 and an isolation acquisition device 102. The connector 101 is connected to a plurality of sensors 1. The isolation acquisition device 102 is connected between the connector 101 and the wireless communication module 200.

[0040] Connector 101 can connect to multiple sensors, consolidating their wiring harnesses. Furthermore, through the collaboration of acquisition circuit 100 and wireless communication module 200, analog signals from multiple sensors can be transmitted wirelessly, eliminating the need for multiple wiring harnesses between sensors and repeaters. Furthermore, isolation acquisition device 102 can isolate and filter analog signals from sensor 1, improving the safety and reliability of the wireless hub.

[0041] Optionally, the acquisition circuit 100 is connected to the sensor 1 through a wiring harness.

[0042] The acquisition circuit 100 is connected to the sensor 1 via a wiring harness, just like a traditional wired hub. Furthermore, the acquisition circuit 100 is connected to the wireless communication module 200, and wireless communication is achieved via the wireless communication module 200. This application combines wireless communication technology with a traditional wired hub to implement a hub with wireless transmission capabilities, reducing the number of wiring harnesses between the sensor and the repeater. During on-site installation, there is no need to lay out the wiring harness between the sensor and the repeater as in related technologies. During maintenance, there is no need to check the wiring harness between the sensor and the repeater as in related technologies. This reduces installation hours and maintenance time, and solves the problem of long wiring harnesses and complex line layout in wired hubs.

[0043] Optionally, connector 101 is an M12 connector. Also known as an M12 circular connector, the M12 connector is used to connect multiple devices or components together to connect circuits, transmit signals, and provide power. The M12 connector is waterproof, dustproof, and vibration-resistant, enabling stable circuit connections and maintaining reliable electrical connections in harsh environments.

[0044] In some embodiments, the isolation acquisition device includes an optocoupler and a Schmitt trigger.

[0045] Optocouplers can isolate input and output voltage signals, providing effective isolation and protection. Schmitt triggers can filter voltage signals to prevent sudden pulse interference. Furthermore, processor 201 in wireless communication module 200 collects the voltage signal transmitted by the Schmitt trigger, converts it into a digital signal, combines the digital signal with data from other channels to form a data frame, and modulates it before transmitting it via the antenna.

[0046] Regarding the wireless communication module 200 .

[0047] In some embodiments, combined Figure 1 As shown, the wireless communication module 200 includes a processor 201 and a signal transmitter 202. The processor 201 is connected to the acquisition circuit 100. The signal transmitter 202 is connected to the processor 201.

[0048] In this embodiment, the wireless communication module 200 achieves data acquisition, processing, and wireless transmission through the collaborative operation of a processor 201 and a signal transmitter 202. The processor 201, as the core control unit, is responsible for data processing and communication coordination; the signal transmitter 202 wirelessly transmits the processed data. This modular design makes the wireless communication module 200 easy to integrate into various devices, facilitating remote communication and data exchange between devices. The processor 201 is connected to the isolated acquisition device 102 of the acquisition circuit 100.

[0049] In some embodiments, processor 201 is a wireless chip.

[0050] A wireless chip is a chip that integrates wireless communication functions. A wireless chip not only has the core functions of a processor, such as data processing and instruction execution, but also integrates a wireless communication module and can directly participate in the wireless communication process.

[0051] Optionally, the wireless chip includes a Bluetooth chip, a Wi-Fi chip, a Zigbee chip, an RFID chip or a GPS chip.

[0052] Optionally, the wireless chip is a Bluetooth chip. A Bluetooth chip is a short-range wireless communication technology chip characterized by low power consumption and low cost. Bluetooth chips enable data transmission and communication between devices using the Bluetooth protocol and are widely used in mobile devices such as mobile phones, computers, and tablets. The transmission range of a Bluetooth chip is generally within 10 meters.

[0053] In some embodiments, signal transmitter 202 is an antenna. Antennas are key components in wireless communication modules, responsible for radiating processed signals into space in the form of electromagnetic waves. Antennas, through their specific physical structure and material properties, effectively convert electrical signals into radio waves, enabling wireless signal transmission. They are an integral part of wireless communication systems and are widely used in mobile phones, base stations, satellite communications, and other fields to ensure smooth information transmission.

[0054] Taking the wireless chip as a Bluetooth chip as an example, the signal transmission of the wireless hub device in this application is explained: the connector 101 collects the analog signal of the sensor, the analog signal is isolated by the optocoupler in the isolation acquisition device 102, and the interference is eliminated by the Schmitt trigger in the isolation acquisition device 102, and then input into the Bluetooth chip. After processing by the Bluetooth chip, the collected analog signal is sent to the repeater in the form of wireless communication to realize signal transmission.

[0055] In some embodiments, combined Figure 1As shown, the wireless hub device is also provided with a power input port 300, which is used to connect to an external power source to power the acquisition circuit 100 and the wireless communication module 200. The power input port 300 is responsible for obtaining an external 24V voltage to power the wireless hub device.

[0056] In some embodiments, combined Figure 1 As shown, the wireless hub device is also provided with an isolated power supply 400, which is arranged between the power input port 300 and the wireless communication module 200. The isolated power supply 400 isolates the power provided to the wireless communication module 200 from the external power supply, ensuring that the wireless communication module 200 is not interfered with by the external power supply.

[0057] Optionally, an isolated power supply 400 is provided between the power input port 300 and the wireless chip. The isolated power supply 400 isolates the power provided to the wireless chip from the external power supply, thereby protecting the wireless chip from interference from the external power supply.

[0058] Optionally, the wireless communication module 200 also includes a watchdog. This is a timer circuit that regularly checks the operating status of the system or program. If it detects a system anomaly or program error, the watchdog triggers a reboot, restoring the system to normal operation. By regularly checking the system's operating status and triggering a reboot, the watchdog effectively prevents program anomalies and system crashes, ensuring the long-term stable operation of the wireless communication module.

[0059] Optionally, the watchdog is an independent timer chip connected to the wireless chip of the wireless communication module. The wireless chip needs to periodically send a "feed the dog" signal to the watchdog (i.e., reset the watchdog timer) to indicate that the system is operating normally. If the watchdog does not receive the "feed the dog" signal within a certain period of time, it is considered that the system may have an abnormality, and the watchdog will trigger a restart operation. In this way, the timer chip is independent of the wireless chip, and even if the wireless chip fails, the watchdog can still operate normally and trigger a restart operation.

[0060] In a second aspect, the present application provides a battery swap station.

[0061] Combine Figure 2 As shown, the battery swap station provided in this application includes multiple sensors 1, a repeater 2 and a wireless hub device in any of the above embodiments. The wireless hub device is used to collect and process the analog signal of the sensor 1 and send the processed analog signal to the repeater.

[0062] Under the premise of adopting the above technical solution, the wireless line collection device of the battery swap station provided by this application is connected to multiple sensors 1 through an acquisition circuit, which can concentrate the sensor 1 wiring harness and collect analog signals from multiple sensors 1; the analog signal can be processed by the wireless communication module and the processed analog signal is sent to the repeater, realizing wireless communication between the wireless acquisition device and the repeater. In this way, the battery swap station provided by this application replaces the wiring harness between the sensor 1 and the repeater in the related art through wireless communication, which is conducive to reducing the length and number of wiring harnesses, simplifying the wiring layout of the battery swap station, and helping to reduce the construction cost and maintenance cost of the battery swap station.

[0063] In some embodiments, combined Figure 2 As shown, the battery swap station also includes a controller 3, which is in communication with the repeater 2. Related technologies use wired cables for sensor signal acquisition and transmission. When there are many sensors or controllers, the controller requires additional expansion modules, which are complex to install and arrange, time-consuming, and expensive. This application builds on the wiring function of traditional wired wiring harnesses and combines them with wireless technology to transmit sensor signals, eliminating the long cables between the hub and the controller.

[0064] Optionally, controller 3 is a PLC (Programmable Logic Controller). A PLC, also known as a programmable logic controller, is a digital computing controller with a microprocessor for automated control. It can load control instructions into memory for storage and execution at any time. A programmable controller consists of functional units such as a CPU, instruction and data memory, input / output interfaces, a power supply, and digital-to-analog conversion.

[0065] In some embodiments, combined Figure 2 As shown, the power swap station includes multiple wireless hubs, each of which is connected to multiple sensors 1, and multiple wireless hubs are connected to the repeater. In this way, wireless hubs can be used to achieve cascading and improve management efficiency.
