[0016] Figure 2 This is a schematic diagram illustrating the distribution of a distributed I / O module, which is an example of this utility model. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] With the development of industrial automation and intelligence, distributed I / O control systems have become an ideal choice for improving the control performance of dehumidifier units due to their advantages such as simple wiring, modular design, ease of maintenance, and high reliability. Therefore, this utility model embodiment provides an electrical control system for a dehumidifier unit using distributed I / O control. This system achieves efficient and precise control of the dehumidifier unit through distributed I / O modules, improving the system's stability, reliability, and energy efficiency.

[0019] Figure 1 This is a block diagram of the electrical control system of a dehumidifier unit according to an embodiment of the present invention.

[0020] like Figure 1 As shown, the electrical control system of the dehumidifier unit includes a main control cabinet 1 and multiple distributed I / O modules located in different areas of the dehumidifier unit 2. Figure 1 The diagram shows three distributed I / O modules: a first distributed I / O module 21, a second distributed I / O module 22, and a third distributed I / O module 23. Each distributed I / O module is connected to the devices in its respective area. Figure 1 (Not shown in the image) are connected together, and all distributed I / O modules are respectively connected to the main control cabinet 1 for communication.

[0021] The distributed I / O module is used to collect data from each device in the area and send it to the main control cabinet 1. It is also used to receive control signals issued by the main control cabinet 1 and send them to each device in the area.

[0022] The dehumidifier unit can be a rotary dehumidifier unit, used for air dehumidification, employing highly efficient moisture-absorbing materials. The dehumidifier unit may also include a regenerative heating device: used to regenerate and heat the moisture-absorbing rotor to restore its moisture-absorbing capacity; it may also include an airflow regulation system: used to adjust the unit's airflow in real time to ensure stable system operation; and it may also include temperature and humidity sensors: monitoring the temperature and humidity in the workshop in real time and feeding the data back to the control system.

[0023] Among them, the distributed I / O module is responsible for collecting and outputting control signals. The main control cabinet 1 realizes real-time monitoring and control of each device in the unit through the distributed I / O module. The main control cabinet 1 communicates with each distributed I / O module through a communication network to realize data transmission. The communication network is an industrial Ethernet or fieldbus.

[0024] In one example, a controller is installed in the main control cabinet. The controller communicates with all distributed I / O modules, and is used to monitor and control the devices in their respective areas through these distributed I / O modules. The controller is a PLC (Programmable Logic Controller).

[0025] Specifically, the working principle is as follows:

[0026] Data acquisition: The first distributed I / O module 21, the second distributed I / O module 22 and the third distributed I / O module 23 respectively acquire data from the devices in their respective areas and send it to the PLC controller in the main control cabinet 1;

[0027] Data processing and analysis: The PLC controller in the main control cabinet analyzes the collected data and performs corresponding controls;

[0028] Control command issuance: The PLC controller sends control commands via 485 communication to adjust the operating status of the rotary dehumidifier and the regenerative heating device;

[0029] Feedback and Optimization: Based on the feedback of environmental parameters, the PLC controller optimizes the control strategy in real time to ensure stable and efficient system operation.

[0030] The embodiments of this utility model have the following advantages:

[0031] 1. Modular design: Distributed I / O modules are installed near each device, simplifying wiring and installation, and improving system maintainability;

[0032] 2. High reliability: Distributed control systems reduce the risk of single points of failure and improve the reliability and stability of the system;

[0033] 3. Precise control: Distributed I / O modules collect and feed back data in real time, enabling the central control system to perform precise control based on actual conditions;

[0034] 4. Flexible expansion: The system has good scalability and can add or remove distributed I / O modules as needed to adapt to application scenarios of different scales;

[0035] 5. Real-time monitoring: Through the distributed I / O module, the central control system can monitor the operating status of each device in real time, promptly detect and handle faults, and ensure the long-term stable operation of the system.

[0036] Therefore, the dehumidifier unit electrical control system of this utility model adopts distributed I / O modules, which has advantages such as modular design, simple wiring, easy maintenance and high reliability.

[0037] In one example, refer to Figure 1 There are three distributed I / O modules: the first distributed I / O module 21, the second distributed I / O module 22, and the third distributed I / O module 23, which are respectively located in the first, middle, and last sections of the dehumidifier unit.

[0038] Furthermore, such as Figure 2 As shown, the equipment in the first section of the dehumidifier unit includes, but is not limited to, at least one of a first regenerative heating device, a first temperature sensor, a valve actuator, a first differential pressure sensor, and a first impeller. The equipment in the middle section of the dehumidifier unit includes, but is not limited to, at least one of a second temperature sensor, a pressure sensor, a second differential pressure sensor, and a first fan. The equipment in the last section of the dehumidifier unit includes, but is not limited to, at least one of a second regenerative heating device, a third temperature sensor, a second impeller, and a second fan.

[0039] The distributed I / O module transmits data from the three control units of the dehumidifier unit (first, middle, and last stages) to the PLC controller. The PLC controller analyzes the collected data and performs corresponding control, and sends control commands via 485 communication to adjust the operating status of the rotary dehumidifier unit and the regenerative heating device.

[0040] Specifically, a complete rotary dehumidifier unit is divided into three independent control units: the first section, the middle section, and the end section. The first distributed IO module 21, the second distributed IO module 22, and the third distributed IO module 23 are used to collect IO point and temperature point information in the first section, the middle section, and the end section, respectively. Then, they are connected to the PLC controller in the main control cabinet through 485 bus communication, so that the whole machine can perform real-time and efficient motion control.

[0041] The distributed I / O architecture significantly improves the overall performance and reliability of the system, making the control system more hierarchical; it reduces maintenance costs and construction difficulty; it greatly enhances the system's scalability, facilitating subsequent system updates and iterations; and by transforming the traditional centralized control system into a distributed control architecture, it significantly improves the overall performance and reliability of the system. Specifically, this system demonstrates significant innovation and superiority in the following aspects:

[0042] 1. Optimized cabling structure: By introducing distributed I / O modules, the cabling complexity within the control system is significantly reduced. Each distributed I / O module directly connects to the sensors and actuators in its area and communicates with the central controller via a communication network. This design not only simplifies the installation process but also reduces the cabling failure rate, thereby improving the overall reliability of the system.

[0043] 2. Enhanced System Scalability: The modular design of the distributed I / O modules makes system expansion extremely convenient. Whether adding new sensors and actuators or expanding the control range, only the corresponding distributed I / O modules need to be added, without large-scale modifications to existing wiring and control logic. This flexibility allows the system to easily adapt to application needs of different scales and complexities, possessing strong adaptability and scalability.

[0044] 3. Reduced maintenance costs: The distributed architecture simplifies system maintenance. Each distributed I / O module operates independently, allowing for rapid fault location and replacement, preventing system paralysis due to a single point of failure. Furthermore, the modular design facilitates system upgrades and maintenance, reducing downtime and maintenance costs.

[0045] In summary, the dehumidifier unit electrical control system of this embodiment, by introducing distributed I / O control technology, thoroughly improves the architecture and performance of traditional rotary dehumidifier unit control systems, providing a highly efficient, reliable, easy-to-maintain solution with strong scalability. This system not only meets the current market demand for high-performance dehumidifier control systems but also reserves ample space for future technological upgrades and expansions, demonstrating broad application prospects.
