Description

Technical Field

[0001] This utility model relates to the field of relay control technology and belongs to a relay control system. Background Technology

[0002] Currently, traditional relay control systems have several drawbacks. Firstly, most traditional systems have relatively simple control methods, only capable of basic switching functions, making it difficult to meet complex logic control requirements. In industrial automated production lines, multiple devices often need coordinated control according to different production processes and technological requirements, which traditional relay control systems struggle to handle flexibly. Secondly, their level of intelligence is low, lacking real-time monitoring and feedback mechanisms. When system faults or anomalies occur, they cannot be detected and alarms issued promptly, leading to lengthy troubleshooting and repair times and impacting production efficiency. Furthermore, traditional relay control systems have poor compatibility; when interfacing with new automated equipment or intelligent control systems, communication protocol incompatibility and interface discrepancies often arise, limiting their application in modern integrated systems. In addition, some traditional systems suffer from poor reliability; after prolonged and frequent relay operation, contact sticking and poor contact can easily occur, reducing system stability and lifespan.

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of this utility model.

[0020] See Figure 1 This application provides a relay control system, including a control host 1. The control host 1 includes a main control computer 11 for issuing control signals containing control parameters and a main control device 12 for receiving and parsing the control signals issued by the main control computer 11. The main control device 12 includes a control module 121 and a drive module 122. The main control computer 11 is connected to the control module 121 of the main control device 12 via a connection line. The control module 121 is connected to a relay module 2, a sensor module 3 and a communication module 4 via a connection line.

[0021] The relay module 2 adopts a PCB board integrated design, which simplifies the structure and saves volume space. It consists of multiple relays of different specifications and types, and the status of each relay contact is connected to the control module 121 through a status feedback line.

[0022] The sensor module 3 includes a variety of sensors and is connected to the control module 121 through analog signal transmission lines or digital signal transmission lines. The control module 121 controls the relay module 2 to operate through the communication module 4 and control signal lines based on the data collected by the sensor module 3 and the preset control strategy, thereby achieving precise control of the external circuit.

[0023] The sensors in the sensor module 3 include a current sensor, a voltage sensor, and a temperature sensor. Each sensor converts the collected physical quantities into corresponding electrical signals according to its own characteristics and transmits them to the control module 121.

[0024] The communication module 4 integrates multiple communication interfaces and is connected to the control module 121 via a communication bus.

[0025] The communication interface includes one or more of RS485, Modbus TCP, Wi-Fi, and Bluetooth, and establishes a communication connection with external devices according to different protocol standards.

[0026] The control module 121 is connected to the drive module 122 via internal wiring.

[0027] In one specific embodiment, a relay control system further includes at least one slave device 5 for extending the functionality of the control system. The slave device 5 has a similar structure to the master control device 12 and is used to extend the functionality of the control system. Both the master control device 12 and the slave device 5 are provided with address information to identify the connection relationship between them.

[0028] The working principle of this utility model:

[0029] After system startup, the main control computer 11 reads the preset control program and parameters, generates control signals, and sends them to the control module 121 of the main control device 12. The sensor module 3 collects electrical and environmental parameters from the circuit in real time and transmits the converted electrical signals to the control module 121. The control module 121 performs logical analysis and judgment based on the preset control strategy and the collected data. When it is necessary to control the on / off state of a circuit, the control module 121 sends a control command to the corresponding relay module 2 through the drive module 122. The relay module 2 receives the command and then acts to switch the circuit on / off. Simultaneously, the control module 121 interacts with external devices through the communication module 4, acquiring real-time operating status information of the external devices and uploading the system's operating status and related data to the remote monitoring center. When the sensor detects an abnormality, the control module 121 immediately issues an alarm and takes corresponding protective measures through the drive module 122, such as cutting off the faulty circuit, to ensure the safe operation of the system. Furthermore, the main control device 12 and the slave device 5 communicate and work collaboratively through address information to jointly complete complex control tasks, thereby expanding the functionality of the control system.
