[0030] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0031] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0032] like Figure 1 As shown, a modular device 1000 for monitoring waterway parameters includes: a base plate 1100, on which a power module 1101, a network communication module 1102, an internal communication module 1104, a digital input module 1103, a platinum resistance patrol meter module 1105 and at least one aviation plug 1106 are arranged; wherein, the power module 1101, the network communication module 1102, the internal communication module 1104, the digital input module 1103, the platinum resistance patrol meter module 1105 and the aviation plug 1106 are connected via a preset connection line inside the base plate 1100, and the dotted line part in the figure provides an optional internal wiring method of the base plate 1100 in this embodiment, and the specific wiring method is not limited by the present invention.

[0033] The aviation plug 1106 is detachably arranged on the periphery of the bottom plate 1100, and each aviation plug 1106 is respectively connected to the waterway detection equipment of the corresponding waterway, wherein the waterway detection equipment includes a water pressure sensor, a water flow switch and a platinum resistance temperature sensor;

[0034] The power module 1101 is connected to an external power source and is used to supply power to the modular device 1000. The power module 1101 is pre-wired and electrically connected to other modules through the bottom plate 1100. The power module 1101 provides necessary power support for the entire modular device 1000 and all its components. It can convert the external power (AC or DC) into the voltage and current required for the operation of each module. It also has functions such as overload protection, short circuit protection and voltage regulation to ensure stable operation of the system.

[0035] The network communication module 1102 is connected to the external control system and is used for data communication with the external control system;

[0036] The network communication module 1102 realizes data communication between the modular device 1000 and the external control system, and can send and receive data through wired or wireless network protocols (such as Ethernet, WiFi, Bluetooth, etc.). It supports multiple communication protocols to ensure compatibility and connectivity with external systems.

[0037] In some embodiments, the network communication module 1102 is a PN (Profinet) communication module, which is a standard based on industrial Ethernet and is used for communication in the field of industrial automation and can provide real-time data exchange.

[0038] In some embodiments, the network communication module 1102 and the power module 1101 can be integrated in the same module. Since these two modules are necessary in the modular device 1000, they can be directly integrated in the same module and connected to the modular device 1000 together. The integrated module reduces the steps and external connections required during the installation process, and simplifies the installation and configuration process of the entire system.

[0039] The internal communication module 1104 is the communication hub inside the module, which is connected to the network communication module 1102, the digital input module 1103, the platinum resistance inspection instrument module 1105, etc. to realize data exchange between modules. The internal communication module 1104 runs an efficient internal communication protocol to realize real-time and reliable data transmission between modules. The internal communication module 1104 is responsible for data exchange and communication between modules inside the device. It allows modules to share data and work together to realize complex monitoring and control processes. Its internal connection can adopt a network structure such as a bus, star or ring to ensure efficient and reliable internal data transmission.

[0040] In some embodiments, the internal communication module 1104 is an RS485 communication module, and S485 provides a highly reliable and flexible way to achieve data communication between devices. The RS485 standard supports long-distance communication and multi-point communication. RS485 uses differential signal transmission, and data is represented by the voltage difference between two lines. This method has high resistance to electromagnetic interference and long-distance transmission loss, and RS485 supports flexible network topologies, including point-to-point, multi-point and ring structures. This provides a variety of layout options for system design.

[0041] The digital quantity input module 1103 is used to receive the switch quantity signals of the electric contact type water pressure sensor and the water flow switch in the waterway detection equipment. The digital quantity input module 1103 can conveniently set the range according to the on-site wiring, and upload the collected digital quantity status to the network communication module through the internal communication module 1104.

[0042] The platinum resistance inspection meter module 1105 is connected to the platinum resistance temperature sensor through the aviation plug 1106, and is used to measure the water channel temperature according to the voltage signal of the platinum resistance temperature sensor, and transmit the measurement data to the internal communication module, and the internal communication module is connected to the network communication module 1102 to transmit the measurement data to the external control system. Among them, the platinum resistance inspection meter module 1105 adopts a multi-channel design, such as 4 channels, 8 channels or more, and each channel can be connected to a platinum resistance temperature sensor through the corresponding aviation plug 1106.

[0043] The aviation plug 1106 adopts a common round metal plug in the industry, which is small in size and has good sealing performance. The aviation plug 1106 is detachably arranged on the periphery of the bottom plate 1100, and each aviation plug 1106 is respectively connected to the waterway detection equipment of the corresponding waterway, wherein the waterway detection equipment includes a water pressure sensor, a water flow switch and a platinum resistance temperature sensor in a wiring manner. This detachable plug-type connection design makes on-site wiring more flexible and convenient, and maintenance and expansion are also more convenient.

[0044] Through the organic combination of the above modules, the modular device 1000 can simultaneously monitor key parameters such as multi-channel water pressure, flow switch status and temperature online, and upload the measurement data to the external control system in real time, providing a basis for automatic control and fault diagnosis of waterways. The device has high integration, convenient installation and maintenance, and strong functional scalability, making it an ideal choice for achieving refined management of waterways. It achieves high flexibility and scalability by integrating modules with different functions.

[0045] like Figure 2As shown, in some embodiments, the modular device 1000 for monitoring waterway parameters can be expanded to include monitoring and regulating water flow, and the modular device 1000 also includes an analog input module 1107, an analog output module 1108, and a digital output module 1109 disposed on the bottom plate 1100. These added modules further enhance the system's capabilities, enabling it to control the waterway system more meticulously and dynamically. The following is a detailed description of these added modules:

[0046] The analog input module 1107 is used to monitor analog parameters in the waterway, such as flow rate, liquid level, etc. The input end of the module is connected to analog output water flow monitors, liquid level meters and other sensors through the aviation plug 1106. The analog input module 1107 has a built-in multi-channel 24-bit Sigma-Delta analog-to-digital conversion circuit, which can collect standard analog signals such as 4-20mA and 0-10V with high precision. After filtering, caching and other processing, the analog data is transmitted to the network communication module 1102 by the internal communication module 1104 to realize real-time monitoring of the analog parameters of the waterway.

[0047] The analog output module 1108 is used to issue analog control instructions to the actuators in the water circuit, such as regulating valves. The input end of the module is connected to the internal communication module 1104 to receive the analog set value from the host computer or control system. The analog output module 1108 has a built-in multi-channel 16-bit digital-to-analog converter and a current / voltage source circuit, which can output standard 0-20mA, 0-10V and other analog control signals, and is connected to the control port of the actuator such as the temperature control valve and the flow control valve through the aviation plug 1106 to realize automatic analog regulation of the water circuit.

[0048] The digital output module 1109 is used to issue switch control instructions to the switch state execution equipment in the waterway, such as electromagnetic valves. The input end of the module is connected to the internal communication module 1104 to receive the switch control command issued by the host computer or control system. The digital output module 1109 has a built-in optocoupler isolation switch amplification drive circuit, which can control the opening and closing states of switch actuators such as multi-channel relays and electromagnetic valves through the aviation plug 1106 to realize automatic switch control of the waterway.

[0049] By expanding the analog input module 1107, the analog output module 1108 and the digital output module 1109, the capability of the modular device 1000 for monitoring waterway parameters is greatly improved. It can not only monitor and collect key analog parameters such as temperature, pressure, flow rate, etc. in the waterway in real time, but also actively adjust the actuators such as regulating valves and solenoid valves through precise analog and switch control signals to realize automatic control of the waterway. The modular device is no longer a passive data acquisition terminal, but an intelligent waterway management system integrating parameter monitoring and control execution.

[0050] This modular and integrated design makes the entire system compact and easy to wire. It can flexibly select corresponding monitoring and control modules according to actual needs, with strong scalability and a wide range of applications. Compared with traditional distributed measurement and control systems, it has higher reliability and economy.

[0051] In some embodiments, for equipment that requires water cooling, the layout of the water system is designed based on achieving the optimal distance between the cooling devices in the equipment and the aesthetics and convenience of the pipeline layout. For example, when the equipment needs to provide cooling for devices A and B at its two ends and device C at the top, it is an effective layout strategy to centrally place the monitoring part of the water system, that is, the modular device 1000, under device C. This configuration allows the water to be distributed from the monitoring part (including monitoring equipment such as electric contact pressure gauges, platinum resistance, water flow switches, etc.) to each device that needs cooling, which not only ensures the effective management of the water flow, but also helps to achieve the beauty and easy maintenance of the entire water system. In addition, the use of a centralized monitoring area is conducive to a clear division of the system functional areas, which is convenient for system integration and subsequent maintenance work.

[0052] like Figure 3 As shown, in some embodiments, the modular device 1000 for monitoring waterway parameters further includes at least one wiring terminal 1110 disposed on the bottom plate 1100 for connecting to other waterway detection equipment.

[0053] One or more wiring terminals 1110 are reserved on the bottom plate 1100. The wiring terminals 1110 use standardized wiring methods, such as screw terminals, spring-type wiring terminals, etc., to facilitate on-site wiring connection of other sensors or detection equipment. The wiring terminals 1110 are connected to the internal communication module 1104 through the wiring inside the bottom plate. In this way, any detection equipment connected to the wiring terminals 1110 can be collected by the internal communication module 1104 as long as its output terminal signal meets the analog or digital quantity standard.

[0054] Common detection equipment that can be connected to the terminal blocks include: ultrasonic level meters, radar level meters and other level sensors; electromagnetic flow meters, vortex flow meters and other flow meters, pH meters, conductivity meters, turbidity meters and other water quality analysis instruments; pressure transmitters, differential pressure transmitters and other pressure detection equipment; switch output type temperature sensors, level switches, etc.

[0055] After the output signals of these devices are connected through the wiring terminals 1110, they can be collected in real time by the modular device 1000 and transmitted to the monitoring center. This "plug and play" open design makes the modular device 1000 no longer a closed single system, but an open platform that can be flexibly expanded according to on-site process requirements. In addition, the wiring terminals can also be used to output some detection data of the modular device 1000 itself to other systems for use, expanding the application range of the data.

[0056] The provision of the connection terminal 1110 greatly improves the flexibility and scalability of the modular device 1000, enabling it to adapt to more complex and changeable application scenarios, thereby meeting different monitoring requirements of waterway management.

[0057] In some embodiments, each module of the modular device 100 is detachable. By adopting a detachable module design, specific monitoring modules can be added, removed or replaced as needed, thereby easily adjusting and optimizing the configuration of the monitoring device.

[0058] In some embodiments, the modular device 1000 can select different modules for installation according to the parameters to be monitored, and the modules can also be expanded. As long as the number of commonly used water channels and the basic parameters to be monitored (the electric contact water pressure gauge corresponds to the water pressure, the platinum resistance corresponds to the water temperature, and the water flow switch corresponds to the switching amount of the water flow: whether there is water flowing), in combination with the aviation plug, the workshop personnel can connect the lines in advance, saving the time of on-site wiring; the use of the aviation plug allows the on-site personnel to only connect the lines of the monitoring device. When it is necessary to determine whether there is a problem with the monitoring device in the future, it is only necessary to swap the aviation plug, which is convenient to replace. At the same time, the use of modular devices can reduce the use of cables. At the same time, for specific monitoring requirements, such as some devices requiring water temperature and water flow to be within a specific range or some devices cannot pass water when not in use, which requires monitoring and controlling specific devices, the corresponding modules and aviation plugs can be added on the original basis to achieve the relevant functions. This design supports customized monitoring needs, allowing the device to adapt to changing application scenarios and technical upgrades.

[0059] At the same time, the design of detachable modules simplifies the maintenance and troubleshooting process. When a module fails, it can be quickly replaced without disassembling or replacing the entire monitoring device, greatly reducing the downtime of the system. In addition, as new technologies emerge, the system can be upgraded by adding or replacing modules.

[0060] In some embodiments, the base plate 1100 of the modular device 1000 is provided with a quick-connect cable, and each module is connected to the quick-connect cable through a standardized interface. The quick-connect cable allows the module to be easily inserted or unplugged from the base plate 1100, and the standardized interface ensures the compatibility between the modules. Whether from the same manufacturer or different manufacturers, as long as the same standards are followed, seamless connection between modules can be guaranteed. By using a quick-connect cable, the possibility of wiring errors can be significantly reduced because the connection method is usually designed to be more intuitive and fault-tolerant. This design allows each module to be quickly and easily connected to the base plate 1100 through a standardized interface. Such a design optimizes the detachability and extensibility of the device, while also simplifying the installation and maintenance process.

[0061] According to a second aspect of the utility model, a waterway parameter monitoring system is provided, which adopts the modular device in any of the above embodiments.

[0062] like Figure 4 As shown, in some embodiments, a waterway parameter monitoring system includes at least one cable connection 2000, each of which includes a set of measuring waterway detection equipment, the waterway detection equipment includes a water pressure sensor, a water flow switch and a platinum resistance temperature sensor. Each waterway corresponding cable connection 2000 is connected to an aviation plug 1106.

[0063] The external control system 3000 is connected to the modular device 1000 and is used to monitor various parameters of each waterway and issue control instructions.

[0064] The design of this waterway parameter monitoring system aims to achieve accurate monitoring of key parameters in the waterway system through an integrated and modular approach. The core of the system is to connect the waterway detection equipment with the modular device 1000 through the cable connection 2000, and then interact with the external control system 3000. The following is a detailed introduction to the composition and working principle of the system:

[0065] The waterway detection equipment may include a water pressure sensor, a water flow switch, and a platinum resistance temperature sensor. These sensors work together to provide real-time data of the waterway system, including water pressure, flow, and temperature. In some embodiments, the waterway detection equipment may also include a pH sensor for measuring the acidity and alkalinity of water, a flow meter for measuring the volume flow of water flow, etc.

[0066] The Cable Junction 2000 connects a group of waterway detection devices to the system. This design simplifies installation and maintenance because all sensors share a single cable, reducing the number and complexity of cables.

[0067] The modular device 1000, as the core of the system, is responsible for collecting data from the waterway detection equipment and forwarding the data to the external control system 3000 through internal processing.

[0068] The external control system 3000 is responsible for analyzing the data received from the modular device 1000 and issuing control instructions as needed to adjust the operating status of the water system.

[0069] In some embodiments, the external control system 3000 includes a programmable logic controller 3100 and a switch 3200 , the switch 3200 is connected between the programmable logic controller 3100 and the modular device 1000 , and the switch 3200 and the power module of the modular device 1000 share the same external power supply 4000 .

[0070] Among them, the programmable logic controller (PLC) 3100 is the core of the external control system and is responsible for executing functions such as logic control, data processing and task scheduling. It can receive the waterway parameters measured by the modular device 1000 and control the system according to preset logic or conditions, such as adjusting the valve state, starting and stopping the pump, etc.

[0071] The switch 3200 connects the programmable logic controller and the modular device, and is responsible for receiving, processing and forwarding data packets. It can support simultaneous communication of multiple devices in the network, thereby improving the efficiency and reliability of data exchange.

[0072] The switch 3200 and the modular device 1000 share the same external power supply 4000. This design simplifies power management, reduces system complexity and additional power requirements. The shared power supply is also conducive to reducing the potential difference between devices and improving the electrical safety of the system.

[0073] The utility model connects the wiring cables of the water channel detection equipment in the water channel system to a modular device through aviation plugs through unified planning. The modular device includes a base plate, on which a power module, a network communication module, an internal communication module, a digital input module, a platinum resistance inspection instrument module and a plurality of aviation plugs are arranged; wherein, each module is connected through a connection line preset inside the base plate, which is convenient for improving the wiring efficiency of on-site installation, reducing the use of cables, and saving wiring installation time.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
