[0023] Example 1
[0024] See Figure 1-3 A data acquisition and storage converter includes a data conversion module and a CAN network bus access module, a data acquisition and storage function module, a timing and positioning module, a network video encoding module, a network switching function module, a status indicator module, and a power management module connected to the data conversion module. The power management module is connected to the data conversion module, the CAN network bus access module, the data acquisition and storage function module, the timing and positioning module, the network video encoding module, the network switching function module, and the working status indicator module to provide power. The CAN network bus access module is also provided with a CAN network bus interface protection circuit module.
[0025] This embodiment completes data acquisition, storage, data parsing, data routing, and video monitoring functions through a CAN network bus access module, a data acquisition and storage module, a timing and positioning module, a network video encoding module, a network switching module, a working status indication module, and a power management module. It realizes seamless cross-network conversion and transmission of data with different transmission rates across different network structures, improving the efficiency of real-time video transmission. The CAN network bus interface protection circuit module of the CAN network bus access module avoids the possibility of lightning strikes when the device bus is operating outdoors, thereby improving the reliability of bus communication. The power management module provides a continuous and stable output power, making the working loop of the data acquisition and storage converter more stable.
[0026] See Figure 2 The CAN network bus interface protection circuit module includes a series topology protection component consisting of a three-level voltage clamping component, a two-level current limiting component, and a one-level high-energy discharge component, which is used to clamp the voltage between the CANH and CANL pins of the CAN network bus access module.
[0027] This embodiment avoids the bus from being struck by high-energy lightning when operating in harsh environments such as outdoors, and meets the protection requirements for electrostatic discharge and surge protection.
[0028] In a specific example, the data conversion module uses an ARM quad-core Cortex A9 CPU.
[0029] In this embodiment, the ARM quad-core Cortex A9 CPU is equipped with embedded software based on the Linux operating system to perform functions such as data acquisition, storage, data parsing, and data routing. It is also equipped with host computer software to read the internal data of the data conversion module. It can be configured as a bus interface. The data buffer interface is cached by the ARM core cache layer of the bus, and the data that needs to be processed is stored in the DDRAM cache layer.
[0030] In a specific example, the CAN network bus access module uses a TJA1040 transceiver to enable communication between modules.
[0031] The circuit in this embodiment uses the TJA1040 transceiver to implement the interface between the CAN controller and the physical bus, as well as the differential transmission and reception functions of the CAN bus.
[0032] In a specific example, the data conversion module is also connected to an interface expansion box, which includes an RJ45 network interface, an RS485 network interface, an RS232 network interface, and a USB bus network interface.
[0033] The data acquisition and storage module of this embodiment can realize real-time acquisition and synchronous storage of data converted by the data conversion module from the CAN network bus access module, RJ45 network interface, RS485 network interface, RS232 network interface and USB bus network interface. The data acquisition and storage module uses 128GB or more of storage space. When the storage space is full, the new data automatically overwrites the oldest data to realize the cyclic storage function.
[0034] It should be noted that the network switching function module in this embodiment can not only realize data exchange and transmission between the CAN network bus interface, RJ45 network interface, RS485 network interface, RS232 network interface and USB bus network interface, but also act as a network switch to enable other network nodes to exchange network data through this device.
[0035] In a specific example, the timing and positioning module uses an ATGM336H-5N module for GPS / BeiDou positioning.
[0036] The ATGM336H-5N module in this embodiment can achieve high-performance BDS / GNSS full constellation positioning, improving the accuracy and speed of timing and positioning.
[0037] In a specific example, the network video encoding module uses an RTSP module.
[0038] This embodiment uses an RTSP module. The RTSP (Real Time Streaming Protocol) module can implement a real-time streaming protocol, which improves the real-time performance of video transmission. The RTSP real-time streaming protocol is an application layer protocol in the TCP / IP protocol suite. In terms of architecture, RTSP is above RTP and RTCP. It uses TCP or UDP to complete data transmission. This protocol defines how one-to-many applications can effectively transmit multimedia data over IP networks.
[0039] In one specific example, the operating status indicator module uses a waterproof, high-brightness LED.
[0040] This embodiment uses working status indicator lights to display various communication and working states of the data acquisition and storage converter.
[0041] In one specific example, the power management module uses the MP2143 chip.
[0042] This embodiment uses a 12-36V DC power input, which is converted by the power management module into the internal operating voltage of the data acquisition and storage converter, thereby powering the data conversion module, CAN network bus access module, data acquisition and storage function module, timing and positioning module, network video encoding module, network switching function module, and working status indication module; for example Figure 3 As shown, the power management module uses the MP2143 chip. Pin 1-PG of the MP2143 chip is used for power indication, pin 2-VIN is used for input power voltage, pin 3-SW is used for switch output, pins 4-GND and 6-GND are used for grounding, pin 5-OUT is used for output voltage feedback, pin 7-FB is used for feedback, and pin 8-EN is used for switch control. An external resistor divider is set between the output terminal and ground to control the output voltage. The above power supply method can provide a continuous and stable output power, thereby making the working loop of the data acquisition and storage converter more stable.
[0043] In summary, this embodiment achieves lightning and surge protection for the CAN bus through multi-level protection circuitry, utilizes a high-stability power management module designed with the MP2143 chip, and expands to multiple network interfaces to achieve cross-network data conversion. This embodiment features a compact structure, strong environmental adaptability, and support for multi-protocol conversion, making it suitable for complex industrial outdoor environments. The above module combination enables the data acquisition and storage converter to operate stably between -40℃ and 85℃, meeting IP67 protection standards and satisfying various demanding industrial applications.
