[0002] When construction projects such as foundation pit excavation or tunneling are carried out in the surrounding environment of a structure, the geological environment and groundwater conditions of the surrounding area will be affected by the construction, which may cause varying degrees of deformation to the structure and the surrounding environment. To ensure the safety of the structure itself, it is necessary to continuously monitor the deformation of the structure.

[0003] In the current field of monitoring and measurement, total stations, as core equipment, are characterized by their large measurement range and high accuracy, and are therefore commonly used in high-precision monitoring scenarios. However, due to limitations such as the low frequency of manual measurements and the influence of personnel skill on measurement accuracy, how to apply total stations to automated monitoring scenarios has become a key issue. This embodiment describes the control circuit of the total station's industrial control computer, primarily used to connect to the network and control the total station for automated measurements. Traditional total station automation industrial control computers connect to the total station via cables, have limited storage of monitoring points, lack functions such as full network adjustment, and their high-power components, such as the core board, operate for extended periods, resulting in high system power consumption and a tendency to crash, severely impacting the reliability of automated monitoring.

[0014] Example 1: In this embodiment, a total station automated monitoring industrial control computer motherboard, such as... Figure 1 As shown, it includes a motherboard unit and a core board that are plugged into each other in parallel; like Figure 2As shown, the motherboard unit includes a main control module, a level conversion module, an RS485 isolation protection module, a gigabit wired network module, a weather meter interface module, a power supply module, and a 4G network communication module, all mounted on the motherboard. The power supply module provides power to the core board, level conversion module, RS485 isolation protection module, gigabit wired network module, weather meter interface module, power supply module and 4G network communication module respectively. The core board is electrically connected to the RS485 isolation protection module, gigabit wired network module, weather meter interface module, power supply module and 4G network communication module respectively through the level conversion module. Both the motherboard and the core board are rectangular.

[0015] The core board is an RK3568 core board, the main control module is an N79E8132AS16 chip, the RS485 isolation protection module is an NSiP83086 chip, and the level conversion module is a UM3202Q chip used for synchronous level conversion of two signals between the motherboard unit and the core board.

[0016] The gigabit wired network module is electrically connected to the core board via an RJ45 interface, which is ESD protected based on the SRV05-4 chip.

[0017] The weather meter interface module uses jumper terminals to switch between I2C and RS485 communication modes.

[0018] The 4G network communication module includes a Mini_PCIE interface and a SIM card slot. The 4G network communication module and the 4G module are electrically connected through the Mini_PCIE interface. The SIM card slot is located on the motherboard and connected to the 4G module.

[0019] In this embodiment, an industrial control computer motherboard for total station automated monitoring is provided. The motherboard's power module provides power to the entire circuit, offering 12V, 5V, 3.3V, and 1.8V power supplies depending on the requirements of each chip. The main control module of the motherboard is connected to the core board via I2C. When the core board does not need to control the total station's operation, calculate data, or upload data, the core board can be set to low power consumption, and the main control module can remain in standby mode while maintaining operation. The core board is then woken up when data acquisition is required. The core board is connected to the RS485 communication module via a level conversion module. The communication module utilizes a full-duplex isolation module to ensure the electrical safety of the motherboard and core board while enabling normal data transmission. This module is mainly used for communication between the industrial control computer and other external devices, such as the total station's protective cover. The core board is directly connected to an RJ45 interface and uses an SRV05-4 chip for ESD protection of the interface, enabling communication and function configuration between the external PC and the core board. The motherboard's weather meter interface communicates with external weather meters via I2C and also has RS485 communication functionality, making it compatible with weather meter modules using different protocols. The motherboard is directly connected to the total station via an RS232 interface, ensuring stable and reliable communication.

[0020] In this embodiment, a total station automated monitoring industrial control computer motherboard, such as... Figure 3 As shown, it mainly consists of a core board, a main control module, a level conversion module, an RS485 isolation protection module, a gigabit wired network module, and a 4G network communication module. The motherboard is rectangular with two rows of sockets in the center for connecting the core board. The core board itself is elongated, and the two are connected in parallel to form the motherboard in this embodiment.

[0021] In this embodiment, a total station automated monitoring industrial control computer motherboard, such as... Figure 4 As shown, the RK3568 core board in the motherboard is directly connected to other modules in the motherboard through interfaces such as UART, USB, RS485, I2C, and GEO. The core board serves as the main data acquisition and processing unit for the total station's operation and data acquisition. like Figure 5 As shown, the core board is equipped with interfaces such as PHY, FSPI, USB_OTG, USB_HOST, PCIE, I2C, HDMI, and UART, which are used to connect devices such as gigabit Ethernet ports, power management modules, USB interfaces, USB hosts, 4G network modules, main control chips, weather meters, HDMI interfaces, and RS485 communication interfaces, which can meet all the data communication needs of industrial control computers. like Figure 6As shown, the main control module inside the motherboard uses the N79E8132AS16 chip, which communicates with the core board through the I2C interface and can control the power supply of the core board. When the core board is not needed to work, the main control chip cuts off the power supply through the power chip and relay, and then starts a timer. After the timer ends, the power is turned on to start the core board. like Figure 7 As shown, the level conversion module within the motherboard uses the UM3202Q chip, or an NMOS transistor. The UM3202Q chip has two input terminals, which can be powered by different voltages. Since the level standards of the core board and other modules within this embodiment differ, a 5V (other modules within the motherboard) and 1.8V (core board) data conversion module is provided to enable data communication. In this embodiment, an NMOS transistor is used to implement a level conversion module between 1.8V and 3.3V to meet the data communication requirements between the main control chip and the core board. like Figure 8 As shown, the RS485 isolation protection module inside the motherboard uses the high-reliability full-duplex isolated RS-485 transceiver NSiP83086 chip with integrated isolated DC-DC power supply, which can effectively improve the security of communication between peripherals and the motherboard. like Figure 9 As shown, the motherboard features a gigabit wired network module that directly connects to the corresponding PHY interface on the core board via an RJ45 interface. The core board incorporates a 100Mbps network driver chip, DM9621, and utilizes an SRV05-4 chip for ESD protection of the network interface, effectively improving the system's adaptability in harsh environments. This interface is primarily used for high-speed communication between external PCs and related equipment and the core board, enabling automated monitoring and control of the total station. like Figure 10 As shown, the weather meter interface module inside the motherboard is set to an I2C interface by default. By reducing the pull-up resistor value, the accuracy of long-distance data transmission between the I2C weather meter and the interface is improved. Simultaneously, a level conversion module is used to directly convert data to the core board, improving overall efficiency. Considering that the weather meter itself uses multiple data communication protocols, an RS485 communication interface is reserved. Communication mode switching can be achieved through jumper terminals, improving the compatibility of the weather meter interface module. like Figure 11 As shown, the motherboard's power module receives an external 12V-20V power supply, which, after passing through relays, powers the total station and the RS485 output interface. The external power input is then converted to 5V and 3.3V via a TPS51120 chip. The 5V power is used for USB, relays, etc., while the 3.3V power is used for the main control chip, level conversion module, 4G module, etc. The 5V power supply is further converted to 1.8V via a TMI3411 chip for powering the core board.

[0022] like Figure 12 As shown, the 4G communication module of the motherboard uses a Mini_PCIE interface. The core board is connected to the 4G communication module of the motherboard. The core board receives the relevant settings transmitted remotely through this module and transmits the measurement results of the total station to the server.

[0023] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
