Description

Technical Field

[0001] The present invention relates to the field of industrial automation control equipment, and particularly to a bus valve island output controller. Background Art

[0002] In the process of industrial automation production, the bus valve island output controller is one of the key devices for realizing automation control. In the prior art, such as the bus valve island disclosed in CN117287550A, the bus control module therein serves as the bus valve island output controller; such as an integrated valve island device disclosed in CN219510239U, the integrated base therein serves as the bus valve island output controller. The above-mentioned bus valve island output controllers all lack the function of assigning a unique communication address to each connected solenoid valve. When multiple solenoid valves are connected simultaneously, due to the lack of address identification, it is difficult for the integrated base to quickly distinguish and identify different solenoid valves, resulting in the control instructions sent by the controller being unable to be accurately transmitted to the corresponding solenoid valve. This will not only cause control delay, but also easily lead to problems such as misoperation of the solenoid valve, seriously interfering with the production rhythm, and even may cause equipment failures or safety accidents, greatly affecting the stability and safety of industrial automation production. Content of the Utility Model

[0003] The purpose of the present utility model: In order to overcome the defects of the prior art, the present utility model provides a bus valve island output controller, which has the function of assigning a unique communication address to each connected controlled element.

[0004] The technical solution of the present utility model: A bus valve island output controller, including a control box and a circuit board module arranged in the control box. A power access element, a network cable socket and an output connector are arranged on the control box, and all are electrically connected to the circuit board module. A rotary encoder switch is arranged on the control box and is electrically connected to the circuit board module. The rotary encoder switch can generate a variety of coding values. Among them, based on the different coding values generated by the rotary encoder switch, the circuit board module establishes a communication connection with a specific controlled element among a plurality of controlled elements.

[0005] By adopting the above technical solution, through the coding setting of the rotary encoder switch, a unique communication address is assigned to each controlled element, avoiding instruction confusion and realizing precise control; at the same time, it supports independent monitoring and management of multiple devices, significantly improving the control efficiency and accuracy of industrial automation production and reducing the risk of misoperation. This kind of switch can quickly set the coding and is often used in occasions where the coding needs to be adjusted frequently.

[0006] In addition, the components of the controller have clear division of labor and close cooperation: the power access element supplies power, the network cable socket transmits data, and the output connector outputs control signals, and cooperates with the electronic control module to complete the control of the controlled element, which conforms to the working logic of a conventional controller.

[0007] A further setting of the present utility model: A plurality of scales and pointers pointing to different scales are provided on the surface of the rotary encoder switch, and both the scales and the pointers are exposed outside the control box.

[0008] With the above further setting, the pointer will point to different scales to indicate the encoded value, and the user can directly observe the scales on the switch to determine the current encoding position.

[0009] A further setting of the present utility model: A switch cover is provided on the control box, and the rotary encoder switch is shielded or exposed by the opening and closing action of the switch cover.

[0010] With the above further setting, the design of the switch cover effectively protects the rotary encoder switch on the one hand, avoids its damage, and prevents communication anomalies caused by inaccurate encoded values; on the other hand, when the switch cover is opened, it is convenient for the user to understand the current encoding.

[0011] A further setting of the present utility model: The switch cover is rotatably inserted on the control box. The switch cover is provided with a hook, and the lower end of the hook has a hook head capable of hooking the control box. On the control box, a bayonet is provided on the outer periphery of the surface of the rotary encoder switch. The bayonet is used to limit the entry and exit of the hook head, and one end of the bayonet has a door opening. The hook head of the hook inserted through the door opening is rotated circumferentially to the lower part of the bayonet to realize the positioning cooperation with the control box.

[0012] With the above further setting, the design of the rotatably inserted switch cover is not only simple to install but also convenient for the user to quickly open and close. When installing the switch cover, the hook head of the hook is inserted downward through the door opening, and the switch cover is rotated so that the hook head rotates to the lower part of the bayonet. The bayonet restricts the hook head from sliding upward, realizing the installation operation of the switch cover. This structure makes the switch cover firmly installed and convenient to disassemble. Compared with the traditional snap or screw fixation method, the operation is more time-saving and labor-saving.

[0013] A further setting of the present utility model: The control box is provided with a power-on status indicator light and a communication quality indicator light. Each indicator light is electrically connected to the circuit board module. The power-on status indicator light is used to indicate whether the bus valve island output controller is powered on, and the communication quality indicator light is used to display the network communication quality status of the bus valve island output controller.

[0014] With the above further settings, by adding a power-on status indicator and a communication quality indicator, users can intuitively understand the operating status of the bus valve island output controller. The lighting of the power-on status indicator indicates that the device has been successfully powered on and entered the standby state. The different display states of the communication quality indicator, for example, if there are three communication quality indicators, represent the quality of communication in different lighting colors or blinking frequencies. Operators can directly and quickly judge whether the device is powered on and the network connection status through the indicator lights, without additional detection tools, reducing the troubleshooting time; it can also provide real-time feedback on the communication quality, facilitating the timely discovery of network anomalies such as weak signals and packet loss, and ensuring the reliability of data transmission.

[0015] A further setting of the present utility model: A buzzer is provided on the control box, which is electrically connected to the circuit board module. The buzzer can cooperate with the indicator lights in a linkage manner to feedback the operating status of the bus valve island output controller through a combination of sound and light.

[0016] With the above further settings, when the bus valve island output controller is in an abnormal state, such as when the power is not connected, a communication failure occurs, or other preset alarm conditions are triggered, the buzzer will emit an alarm sound at a specific frequency, and at the same time, cooperate with the display of the indicator lights, such as flashing or changing to a specific color, to form a dual alarm signal of sound and light. This design of linkage cooperation not only enhances the intuitiveness of the alarm but also improves the visibility of the alarm, ensuring that operators can quickly notice the abnormal state of the device even in a noisy or poor visibility environment, and take timely measures to handle it, avoiding the expansion of faults or the occurrence of safety accidents.

[0017] A further setting of the present utility model: A reset button and a restore button are provided on the control box, and each button is electrically connected to the circuit board module. The reset button is used for the restart operation of the bus valve island output controller; the restore button is used to restore the bus valve island output controller to the factory default state after a long press for a set time.

[0018] With the above further settings, the reset button can quickly solve temporary faults during the operation of the device, such as program jams, reducing the downtime; the restore button supports one-key restoration of the default configuration, facilitating device maintenance or debugging, avoiding complex manual parameter resetting, and reducing the operation threshold and maintenance cost.

[0019] A further setting of the present utility model: Each side of the control box is provided with a screw passing channel, and the side of the screw passing channel is of an open structure.

[0020] With the above further settings, compared with the closed structure, the open design simplifies the screw installation process. The screw can be inserted from the side opening without having to fully align the holes, greatly improving the installation efficiency.

[0021] Further setting of the present utility model: The control box includes a bottom shell and an upper cover which are detachably connected. The circuit board module includes a first circuit board and a second circuit board arranged in an up-and-down structure. Among them, a rotary encoder switch, an indicator light, a button and a network cable socket are integrally arranged on the first circuit board. The upper cover is correspondingly partitioned into a coding area, an indicator light area and a button area. The network cable socket is externally arranged at one end of the bottom shell. The second circuit board integrates an output connector and a power access component. The output connector protrudes from the lower bottom surface of the bottom shell. The power access component is of a terminal block structure. There is an inlet for the power cable on one side of the control box corresponding to the power access component.

[0022] With the above further setting, the detachable structure of the control box is convenient for maintenance and replacement of damaged components, reducing the complexity of maintenance.

[0023] The first circuit board integrates a rotary encoder switch, an indicator light, a button and a network cable socket. The upper cover is correspondingly provided with a coding area, an indicator light area and a button area. Such a design enables users to intuitively operate and monitor the device status, improving the usability of the device. The second circuit board integrates an output connector and a power access component. The output connector protrudes from the lower bottom surface of the bottom shell, facilitating connection with other devices. The power access component is of a terminal block structure, facilitating the access of the power cable. At the same time, an inlet for the power cable is provided on one side of the control box, enabling the power cable to be neatly connected and avoiding the problem of messy cables.

[0024] Purpose of the present utility model: In order to overcome the defects of the prior art, the present utility model provides a bus valve island output control system.

[0025] Technical solution of the present utility model: A bus valve island output control system includes a controller. The circuit board module has a processor, an Ethernet communication module, a storage module and an optocoupler drive output module. The processor is respectively connected to the Ethernet communication module, the storage module, the rotary encoder switch, the button module, the indicator light control module, the buzzer and the optocoupler drive output module.

[0026] The Ethernet communication module is communicatively connected to the PLC through the network cable socket. The optocoupler drive output module is connected to the controlled component through the output connector. The button module includes a reset button and a restore button. The indicator light control module includes a power-on status indicator light and a communication quality indicator light.

[0027] By adopting the above technical solution, the processor coordinates each functional module to build an efficient data processing and communication network, supporting stable interaction with the PLC and the controlled component. The modular design enhances the scalability of the system, and functional modules such as increasing the storage capacity or upgrading the communication protocol can be flexibly added or deleted according to production requirements, improving the adaptability and intelligence level of the industrial automation system.

[0028] The storage module is used to store the working parameters and status information of the device to ensure the persistent preservation of data in the event of a power outage. The processor, as the core control unit, is responsible for receiving instructions from the PLC, realizing the rapid transmission and parsing of data through the Ethernet communication module, and at the same time performing read and write operations on the data in the storage module according to the preset logic. The optocoupler drive output module is responsible for converting the control signal of the processor into a level signal suitable for driving the controlled components and stably and reliably transmitting it to the controlled components such as solenoid valves and relays through the output connector.

[0051] As Figure 8 shown, the bus valve island output control system of the present utility model includes the above-mentioned bus valve island output controller, wherein the circuit board module has a processor, an Ethernet communication module, a storage module, and an optocoupler drive output module. The processor is respectively connected to the Ethernet communication module, the storage module, the rotary encoder switch, the button module, the indicator light control module, the buzzer, and the optocoupler drive output module;

The processor determines which group of solenoid valves corresponding to the coding is to be controlled. When the Ethernet communication module transmits the received PLC instruction to the processor, the processor sends a control signal to the corresponding destination solenoid valve through the optical coupling drive output module according to the instruction content and the coding information of the rotary coding switch, so as to achieve precise control of the controlled element.
