Description

Technical Field

[0001] This utility model relates to the field of automated measurement and control technology, and in particular to a general integrated measurement and control system. Background Technology

[0002] In the construction of national water network projects, small and medium-sized reservoirs, and irrigation district projects, the demand for multi-disciplinary integrated measurement and control is both numerous and urgent. Providing users with a series of measurement and control modules within a single project not only helps reduce construction costs during the construction phase but also enables centralized and unified convenient operation and maintenance during the operational phase. While some solutions attempt integration at specific levels or for specific objects, they do not achieve true underlying hardware integration and functional modularization. For example, some sluice gate control cabinets integrate gate control, water level monitoring, and video surveillance functions, which can be seen as an extension of the core function of "gate monitoring." Similarly, some reservoir or sluice gate safety monitoring systems can integrate data from multiple sensors, such as structural displacement, stress and strain, and seepage pressure. In summary, existing measurement and control equipment suffers from complex interfaces, differing protocols, and numerous data barriers due to its division into different disciplines such as automation, hydrological and meteorological monitoring, and safety monitoring, making integration with third-party platforms difficult.

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 As shown in the figure, this utility model embodiment provides a general integrated measurement and control system consisting of a main processing module and multiple expansion modules; wherein, the main processing module integrates a central control unit (CPU), a power management unit, a communication interface unit, a digital input (D / I) unit, a digital output (D / O) unit, an analog input (A / D) unit, a sensor interface unit, and a storage expansion unit, and undertakes functions such as data acquisition, processing, storage, and command issuance.

[0018] Among them, the central control unit (CPU): the main monitoring module completes data processing, interprets and executes user programs, communication, etc., supports monitoring and professional hydrological surveys, self-reporting functions, supports time synchronization, supports automatic restart and network reconnection in case of failure, and supports automatic identification of expansion channel modules and communication modules, as well as communication module expansion and other functions.

[0019] Power Management Unit: Supports wide voltage input (DC 12~24V), has overvoltage and overcurrent protection functions, supports the connection of batteries and photovoltaic power sources, realizes self-adaptation and charge / discharge management of batteries, and adapts to unstable power environments in industrial sites.

[0020] Communication interface unit: Ethernet, RS232, RS485 and other interfaces are used to connect the expansion communication module and the main processing module.

[0021] Digital input (D / I) unit: Acquires status signals of field devices (such as gate opening, closing, fully open, fully closed, water pump start, stop, etc.) as well as the control system's own permission mode, power status, fault signals, etc.

[0022] Digital input / output (D / O) unit: Outputs digital control signals (such as relay switching signals) to drive field actuators (such as valves, alarms, etc.).

[0023] Analog input (A / D) unit: Converts analog signals from sensors (such as 4~20mA signals of vibration, pressure, and water level) into digital signals with an accuracy of up to 16 bits, and supports multi-channel synchronous acquisition.

[0024] Sensor interface unit: It can acquire and process sensor data (such as discharge flow rate, water level before and after the gate) by adaptively connecting to various external sensor interfaces such as pulse quantity, SDI-12, RS485, RS232, etc.

[0025] Storage expansion unit: Based on the need for local storage of historical data, it supports the expansion of storage space through methods such as SD cards, flexibly meeting different customer usage and data export needs.

[0026] The expansion module is based on the standardized interface design of the main processing module and can be flexibly selected according to scenario requirements, covering multiple professional applications. Among them, Automation control expansion modules: including four types of expansion modules: DI, DO, AI, and AO, which can support PLC logic control and interface with field solenoid valves, motors and other equipment to realize the status acquisition and control of field equipment; Engineering safety monitoring expansion module: Connects to sensors for vibration, displacement, stress, etc., for monitoring structures such as bridges and dams; Water and rainfall monitoring expansion module: connects to water level gauges, rain gauges, and flow meters for hydrological station monitoring; Environmental monitoring expansion module: Connects to temperature, humidity, and gas sensors for industrial site environmental monitoring; Wireless communication expansion module: Supports configuration of LoRa, ZigBee, Wi-Fi and other wireless communication methods, enabling LAN networking and low-latency data transmission. The master-slave modular design allows the system to quickly adapt to scenarios involving multiple disciplines and devices. During on-site implementation, only the expansion module needs to be selected based on requirements, eliminating the need to redeploy the entire system and improving implementation efficiency.

[0027] To address communication needs in harsh environments (such as remote mountainous areas, industrial workshops, and outdoor water conservancy facilities), this system employs a multi-standard hybrid networking technology, supporting multiple communication methods including 4G / 5G, Wi-Fi, LoRa, and Ethernet, achieving "wide coverage, high reliability, and low latency" communication capabilities. The communication network uses a star + mesh hybrid topology. For example... Figure 2 As shown, star topology: The main control system acts as the central node, and the network is connected via Ethernet to realize data interaction of extended systems (such as automation control modules in the workshop). The latency is ≤10ms, and it is mainly used for industrial equipment and water conservancy facility control.

[0028] like Figure 3As shown, the Mesh network extends to form a self-organizing network via LoRa or ZigBee, suitable for remote areas (such as mountain dam monitoring), with a coverage range of up to 5km. It supports automatic node repair (when a node fails, data is automatically routed to other nodes), improving reliability to 99.9%. The communication module employs dual-path backup (such as 4G + BeiDou), automatically switching to the backup link when the primary communication link fails, with a switching time of ≤1s, ensuring no data loss.

[0029] Taking engineering safety monitoring scenarios as an example, sensor protocols are diverse (such as Modbus RTU, SL651, SL427, and custom protocols). Traditional systems require manual configuration of protocol parameters, which is inefficient and prone to errors. The mixed-test module in this invention adopts automatic protocol identification and conversion technology to achieve "plug-and-play" sensor access. In the module's hardware design, the mixed-test module integrates a protocol identification unit, a protocol conversion unit, and a data caching unit. It has a built-in protocol feature library (such as Modbus RTU). By sending detection commands (such as sending the Modbus RTU 0x03 register read command to the sensor), it receives the sensor's response signal and matches the protocol features in the feature library. The identified sensor protocol is converted into a unified internal protocol (such as a standard format based on JSON) to ensure that the main processing module can process the data uniformly.

[0030] Through the above embodiments, the universal integrated measurement and control system of this utility model successfully achieves deep integration of multiple professional functions, plug-and-play sensors, and stable and reliable data communication, effectively solving the various problems raised in the background art. Those skilled in the art can select appropriate components and program the functional logic based on the above description to manufacture and use this system.
