Detailed implementation manners

[0021] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that for the convenience of description, only the parts related to the invention are shown in the drawings.

[0022] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0023] Embodiment 1 In order to make the technical solutions of the embodiments of the present application clearer and easier to understand, the application background provided by the embodiments of the present application will be introduced below.

[0024] With the progress of technology and the continuous development of electronic technology, integrated measurement and control devices have gradually integrated multiple functions and technologies, achieving a high degree of integration of hardware and software. This integrated development makes the measurement and control devices more compact and portable, while improving the stability and reliability of the system. For example, in modern industrial and automation systems, the real-time acquisition and processing of data are crucial, so the role of integrated measurement and control devices becomes particularly obvious; traditional measurement and control devices are usually composed of multiple independent modules, connected to each other through cables, and have problems such as complex wiring, low reliability, and poor scalability.

[0025] Integrated measurement and control devices can be conveniently connected to sensors and actuators in various scenarios such as aerospace, weapons and ships, rail transit, water conservancy and electromechanics, petrochemical industry, environmental monitoring, production sites, and scientific experiments. Taking the aerospace field as an example, in the rocket launch control system, the integrated measurement and control device can achieve real-time monitoring and control of various systems of the rocket, ensuring the safety and stability of the rocket launch. Specifically, it can meet the measurement and control requirements of rocket launches and achieve multiple technological innovations such as embedded launch control, ground-to-rocket Ethernet, and self-developed power measurement and launch control systems.

[0026] In view of this, in order to improve the integration, reliability and flexibility of the system, it is necessary to design a highly integrated measurement and control device that can realize multiple functions such as multi-channel analog signal acquisition, digital signal processing, network communication and power management. Specifically, the embodiments of the present application propose a highly integrated measurement and control device, aiming to solve the problems of complex wiring, low reliability and poor scalability existing in traditional measurement and control devices. The system integrates multiple functional modules, including a signal input module, a digital processing module, a communication module and a power supply module, and is applicable to application scenarios such as industrial automation, environmental monitoring, data acquisition, etc.

[0027] Specifically, please refer to Figure 1 and 2 the structural schematic diagram and the overall structural schematic diagram of a highly integrated measurement and control device provided by this embodiment shown in the figure, including: A signal input module 1, the signal input module 1 includes: at least two analog-to-digital converters 11, and the two analog-to-digital converters 11 share the same reference voltage and both have multiple acquisition channels; the signal input module 1 is used to receive an external analog signal and convert it into a corresponding digital signal; A digital processing module 2, the digital processing module 2 includes a controller 21, and the controller 21 is used to receive and process the digital signal to obtain a corresponding drive control signal to control an external device connected to the signal of the measurement and control device; A communication module 3, the communication module 3 is signal-connected to the controller 21 and is used to realize data transmission between the control unit 21 and the external device; the communication module is also integrated with a real-time operation unit, and the real-time operation unit can allow multiple communication ports to access the highly integrated measurement and control device at the same time.

[0028] In the embodiment of the present application, the measurement and control device body A has a modular design, including a signal input module 1, a digital processing module 2, a communication module 3, and a subsequent power supply module 4. With such a design, the use of external cables can be effectively reduced, and the cumbersome process of system design can also be simplified. Specifically, the signal input module 1 can also be called an analog signal input module, which can receive analog signals from multiple sensors connected to it. The signal input module 1 includes at least two analog-to-digital converters 11. Here, the analog-to-digital converter 11 can be selected as the ADS8598S analog-to-digital converter. The ADS8598S analog-to-digital converter is used to collect analog signals from -10V to 10V, and has the characteristics of high precision and low power consumption, and can realize synchronous acquisition of multi-channel analog signals. Finally, the two ADS8598S analog-to-digital converters can receive a total of 16 channels of sensor input signals, and the sampling rate of each channel can be independently adjusted, improving the flexibility of the measurement and control device. It should be noted that the design of sharing the same reference voltage by the two analog-to-digital converters 11 enables each acquisition channel to share 1 high-precision reference voltage. After the whole machine is calibrated at the factory, good consistency of 16-channel analog quantity acquisition can be achieved.

[0029] The digital processing module 2 is the core processing unit of the measurement and control device. The digital processing module 2 includes a controller 21. The type of the controller 21 can be selected as the STM32G474V controller. The controller 21 is communicatively connected to the analog-to-digital converter 11 through the SPI interface, and then receives and processes the data of the digital signals from the ADS8598S, and outputs the required drive control signals to the external devices connected to the measurement and control device (such as heaters, coolers, motors, solenoid valves, flow valves, etc., supporting ordinary on-off control, motor forward and reverse control, PWM control, combinational logic control, etc., and the switching frequency can reach dozens of KH). Here, it needs to be explained that the control logic between the analog signal input to the measurement and control device and the output drive control signal is completed by the preset algorithm inside the controller (such as the temperature control closed-loop algorithm, the fan speed regulation algorithm, or the heating sheet PWM power adjustment, etc.). In this way, through the high-performance microcontroller and the high-precision analog-to-digital converter, the real-time performance and accuracy of data processing are also ensured.

[0030] The communication module 3 is the communication unit of the measurement and control device. This communication module 3 has two communication ports, which are respectively connected to the controller 21 through the SPI interface and the UART interface for realizing signal transmission between the control unit 21 and external devices in different scenarios, making the measurement and control device more practical; at the same time, by integrating the real-time operation unit, it can meet the simultaneous access of multiple external software interfaces and ensure that the data is the latest and conflict-free; specifically, the real-time operation unit can also be called RTOS, which supports multitasking. Task scheduling is based on priorities, which can ensure the timely execution of critical tasks and is helpful for processing multiple communication interfaces simultaneously. In RTOS, independent tasks are created for each interface, and each task is responsible for processing the data reception and transmission and protocol parsing of the corresponding interface, uniformly processing requests of the application logic, and ensuring data consistency through a synchronization mechanism. These tasks need to interact with the core control logic of the device, share data or resources, so the synchronization and communication mechanisms between tasks in the real-time operation unit need to be considered.

[0031] In addition, in terms of the hardware of the real-time operation unit, it is necessary to confirm whether the single-chip microcomputer has sufficient processing power and memory to run the Web server. If the resources of the single-chip microcomputer are limited, lightweight protocols and libraries can be selected. In terms of the software architecture, hierarchical processing is required: the bottom layer is the hardware driver, including serial port drivers, Ethernet drivers, etc.; the middle layer is the protocol processing, including Modbus RTU serial port, Modbus TCP network port, and HTTP / WebSocket processing. The upper layer is the application logic, which processes requests from different interfaces and executes corresponding control commands and returns data.

[0032] Furthermore, for the task division of RTOS: (1) Serial port task: responsible for reading and writing serial port data, parsing commands of Modbus RTU or other serial port protocols, forwarding requests to the application logic, and returning responses; (2) Network task: uses the IwIP protocol stack to handle TCP connections, listens on the Modbus TCP port, parses requests and forwards them to the application logic, and also processes and returns responses; (3) Web server task: runs a lightweight HTTP server, uses WebSocket for real-time communication, and needs to handle the transmission of HTML / CSS / JS files and the refresh of dynamic windows; (4) Application logic task: processes requests from different interfaces, accesses shared resources (such as sensor data, control signals, etc.) and ensures thread safety; (5) When multiple interfaces send control commands simultaneously, it is necessary to design priorities or a queue mechanism to process them in order; (6) Dynamic memory allocation is prone to fragmentation in embedded systems, and static memory allocation needs to be adopted.

[0033] In a preferred embodiment, the digital processing module 21 further includes: a field effect crystal structure 22 and a digital temperature sensor 23 connected to the controller 21; an output end of the field effect crystal structure 22 is connected to the external device; wherein, the field effect crystal structure 22 is configured to control the operation of the external device; the digital temperature sensor 23 is configured to collect the temperature in the temperature environment and generate a corresponding temperature signal.

[0034] Specifically, the field effect crystal structure 22 is an 8-channel MOSFET (Metal Oxide Semiconductor Field Effect Transistor) with opto-isolated drive, specifically a drive circuit formed by at least eight MOSFET transistors respectively, forming multiple control channels; the drive circuits formed by different MOSFET transistors can be used to drive different components, and each drive circuit realizes signal isolation between input and output through a first opto-coupler. Such a structure can be used to control the switching of high-power devices, and at the same time, by designing the first opto-coupler, electrical isolation is achieved, improving the reliability and safety of the system.

[0035] Then, after the controller 21 outputs a drive control signal, the controller 21 can transmit the drive control signal to the 8-channel MOSFET with opto-isolated drive, and then transmit it to the corresponding actuator through a connector externally connected to the drive end of the MOSFET, thereby realizing closed-loop control functions such as temperature, flow rate, combustion, and fan.

[0036] In addition, a digital temperature sensor 23 is also integrated inside the measurement and control device to monitor the temperature environment inside the measurement and control device in real time, ensure that the measurement and control device can operate within a safe range, provide data support for decision-making, and further improve the safety of the system.

[0037] In a preferred embodiment, the communication module 3 includes: a first communication port and a second communication port; The first communication port is a 100M Ethernet port 31, and the second communication port is an isolated asynchronous 422 network interface 32; the first communication port is used for high-speed data transmission and remote communication, and the second communication port is used for local area network communication and distributed control communication.

[0038] Specifically, the 100M Ethernet port 31 is communicatively connected to the controller 21 through the SPI interface, and the isolated asynchronous 422 network interface 32 is communicatively connected to the controller 21 through the UART interface. Among them, the 100M Ethernet port 31 supports two access methods: the Web end and the host computer software. The isolated asynchronous 422 network interface 32 supports host computer access. A total of three access methods are independent of each other and support simultaneous access and control by all three under the design of the real-time operation unit to adapt to different application environments. Among them, the Web end can cross operating systems and can achieve control operations through Linux devices, mobile Android devices, etc. Both the 100M Ethernet port 31 and the isolated asynchronous 422 network interface 32 are equipped with complete host computer software, which can display AD data, DO / DI status, temperature, etc. in real time and have functions such as data saving, playback, time stamping, and plotting. The design of multiple communication interfaces can not only ensure that the measurement and control device can meet the measurement and control of various complex working conditions and ensure the reliable transmission of data in a complex electromagnetic environment, but also support multiple communication interfaces and network protocols, facilitating the expansion and upgrade of the system.

[0039] Furthermore, In a preferred embodiment, the measurement and control device further includes: a power supply module 4, and the power supply module 4 is used to supply power to the signal input module 1, the digital processing module 2, and the communication module 3. The power supply module 4 includes at least two circuit channels, and each circuit channel includes an isolator, a low dropout linear regulator, and a DC-DC converter for outputting a stable voltage and isolating interference between modules.

[0040] Specifically, to ensure the stable operation of the measurement and control device, the power supply module 4 is also an essential part. In the embodiment of the present application, the power supply module 4 is used to supply power to the signal input module 1, the digital processing module 2, and the communication module 3. The power supply module 4 includes two circuit channels, and each circuit channel includes an isolator (for example, an optical coupler or a magnetic coupler), a low dropout linear regulator (LDO), and a DC-DC converter. It can not only be used to convert the input 9V - 36V DC voltage into a stable output voltage for use by each module inside the measurement and control device, but also provide electrical isolation to ensure the independence and safety of each module of the system.

[0041] In a preferred embodiment, the measurement and control device further includes: an optocoupler detection circuit structure 24; the optocoupler detection circuit structure 24 is connected to the controller 21 and is used to implement signal isolation and transmission between input and output. Specifically, the optocoupler detection circuit structure 24 is a circuit structure composed of at least four second optocouplers; in practical applications, the 4-channel optocoupler detection circuit can detect different network signals (for example, IP network signals, ATM network signals, serial communication signals, and parallel communication signals) respectively, so as to ensure the communication reliability of the measurement and control device. The design of the optocoupler detection circuit structure 24 improves the anti-interference ability and reliability of the measurement and control device, and ensures stable operation in a complex electromagnetic environment.

[0042] Based on the above description, it can be known that in the embodiment of the present application, an efficient integrated measurement and control device is proposed. This measurement and control device integrates multiple functional modules on one platform. The functional modules include: a signal input module 1, a digital processing module 2, a communication module 3, and a power supply module 4; both of the two analog-to-digital converters 11 in the signal input module 1 have multiple independently controllable acquisition channels, which are used to access specified sensors and receive the analog signals collected by the sensors in real time, and at the same time convert the analog signals into digital signals that can be processed by the controller 21. Based on the collected analog signals, according to the policy logic set inside the controller 21, a drive control instruction for the target component of the external device that needs to act currently is output, and the target component is driven by the MOSFET tube corresponding to the target component to respond to the drive control instruction.

[0043] The measurement and control device in the embodiment of the present application adopts a "collection - processing - output" system architecture, is compatible with most sensors (pressure, temperature, heat flux, gas, noise, vibration, etc.) and actuators (heater, cooler, motor, solenoid valve, flow valve, etc.) in the industrial control field, and is applicable to industrial control systems that require collection and control in aerospace, ordnance and shipbuilding, rail transit, etc. It can quickly build a closed-loop control system, such as temperature control, water pump / solenoid valve control, motor control, harmful gas detection, etc. The communication protocol is open source and supports secondary development, with strong practical value; at the same time, the measurement and control device also has advantages such as high integration, high reliability, flexible expansion, and high performance.

[0044] Embodiment 2 Combined with Figure 3 , and based on an efficient integrated measurement and control device described in Embodiment 1, the embodiment of the present application proposes a control method for an efficient integrated measurement and control device, and this control method includes: S100. Receive a first input electrical signal input via the acquisition channel of the signal input module 1, and convert the first input electrical signal into a first digital signal; S200. Input the first digital signal into the controller 21. The controller 21 performs smoothing filtering on the first digital signal and obtains a first drive control signal through a preset algorithm. S300. Transmit the first control signal to the field effect crystal structure 22, and the field effect crystal structure 22 controls the actuator of the external device to act.

[0045] Specifically, in the control method of the high-efficiency integrated measurement and control device, it is necessary to connect the sensor input interface and the control output interface of the high-efficiency integrated measurement and control device to the corresponding sensors and the actuators of the external device respectively in advance, so that signals can be transmitted. At the same time, the external device also needs to be connected to the software interface of the measurement and control device to achieve communication transmission between each other (obtain access rights and acquire data to enable other software functions).

[0046] Furthermore, the measurement and control device receives the first input electrical signal sent by the sensor through the acquisition channel. Then, the analog-to-digital converter 11 in the signal input module 1 converts the first input electrical signal into a first digital signal and outputs the first digital signal to the controller 21. The controller 21 performs smoothing filtering on the first digital signal to filter out singular signal points, and judges the measures that the current external device should take according to the internal preset algorithm and the filtered first digital signal, and outputs the corresponding first drive control signal. The first drive control signal includes: the actuator and the corresponding action instruction. The controller controls the corresponding actuator to act by identifying the control channel inside the field effect crystal structure 22 corresponding to the actuator through the corresponding MOSFET transistor. Accordingly, the high-efficiency integrated measurement and control device in the embodiment of the present application has strong versatility and can be widely applied to the following scenarios: (1) Industrial automation: used for data acquisition and control on the production line to improve production efficiency and product quality; (2) Environmental monitoring: used for real-time monitoring of environmental parameters to provide data support for decision-making; (3) Data acquisition: used for various scientific research experiments and data acquisition projects to provide high-precision and real-time data; (4) Intelligent transportation: used for traffic signal control, vehicle monitoring, etc. to improve the intelligent level of traffic management.

[0047] In a preferred embodiment, the method further includes the following steps: Obtain the real-time environmental temperature, and perform fault diagnosis on the measurement and control device based on the value of the real-time environmental temperature. If the value of the real-time environmental temperature is greater than or equal to the preset temperature threshold, it is confirmed that the measurement and control device is in a fault state.

[0048] Specifically, a digital temperature sensor 23 is further included in the measurement and control device, which can monitor the temperature environment inside the measurement and control device in real time. When the value of the real-time ambient temperature obtained is greater than a preset temperature threshold (this threshold is set according to the actual measurement and control device and is not specifically limited here), it is determined that the measurement and control device is in a faulty state and there is a risk of incorrect data transmission. In this way, it can be ensured that the measurement and control device can operate within a safe range, provide data support for decision-making, and further improve the security of the system.
