[0039] The present application is further described in detail below with reference to the accompanying drawings.

[0040] REFERENCE Figure 1 A structure schematic diagram of a PLC controller of a general electronic tube transmitter is provided for the embodiment of the present application, the PLC controller includes a signal acquisition module, a PLC switch quantity processing module, a CPU processing module, a display control board, and a power module, wherein:

[0041] The signal acquisition module is connected with an external electronic tube transmitter, and is used to acquire working state signals and operation state signals of the electronic tube transmitter;

[0042] The CPU processing module is connected with the signal acquisition module, the PLC switch quantity processing module and the display control panel respectively, and is used for generating a state display signal according to the working state signal and the operation state signal, outputting the state display signal to the display control panel, and generating an output control signal according to an input control signal inputted by the display control panel through the PLC switch quantity processing module, and outputting the output control signal to the PLC switch quantity processing module.

[0043] The display control panel is connected with the PLC switch quantity processing module, and is used for visually displaying the working state and the operation state of the electronic tube transmitter according to the state display signal, and sending a received control instruction to the PLC switch quantity processing module.

[0044] The PLC switch quantity processing module is connected with the electronic tube transmitter, and is used for converting the output control signal into a PLC control signal adapted to the electronic tube transmitter, and converting the control instruction into the input control signal.

[0045] The power module is connected with the signal acquisition module, the PLC switch quantity processing module, the CPU processing module and the display control panel respectively, and is used for providing a working voltage.

[0046] In the embodiment, the PLC controller adopts a modular design, aiming at realizing general control of various high-power electronic tube transmitters. The controller is composed of a signal acquisition module, a CPU processing module, a display control panel, a PLC switch quantity processing module and a power module, so as to ensure maximum universality and adaptability.

[0047] The main function of the signal acquisition module is to acquire the working state signal and the operation state signal of the electronic tube transmitter. The design of the signal acquisition module considers the signal characteristics of different types of transmitters, and through flexible interface design and configurable signal definition, the controller can adapt to the output characteristics of various transmitters. The acquired signals are then transmitted to the CPU processing module. In order to realize universality, the module can adopt various types of signal interfaces, including analog interfaces (such as 4-20mA, 0-10V, etc.) and digital interfaces (such as RS485, RS232, etc.). At the same time, the signal acquisition module adopts high-precision sensors and data conversion technology to ensure that the acquired signals are accurate and reliable, thereby improving the response speed and control accuracy of the entire control system.

[0048] The CPU processing module first generates a status display signal based on the operating status signal and the operation status signal obtained from the signal acquisition module, and outputs it to the display control board. This process realizes real-time monitoring and visual display of the transmitter status, which helps the operator quickly understand the system operation. At the same time, the CPU processing module is also responsible for processing the input control signal converted by the PLC switch quantity processing module from the display control board, generating the corresponding output control signal, and sending it to the PLC switch quantity processing module. This two-way information flow design ensures accurate execution of control instructions and timely feedback of system status.

[0049] The display control board is connected to the PLC switch quantity processing module, and its design purpose is to provide an intuitive man-machine interface for the operator. The display control board displays the operating status and operating status of the tube transmitter in a visual manner based on the status display signal received from the CPU processing module. This design greatly improves the operability and monitoring efficiency of the system. In addition, the display control board can also receive the control instructions input by the operator and send them to the PLC switch quantity processing module, realizing the bidirectionality of man-machine interaction and enhancing the controllability and flexibility of the system.

[0050] The PLC switch quantity processing module plays a key interface role in the entire PLC controller. It is directly connected to the tube transmitter and is responsible for converting the output control signal received from the CPU processing module into a PLC control signal compatible with the tube transmitter. This signal conversion process ensures that the control instructions can be correctly understood and executed by the transmitter. At the same time, the PLC switch quantity processing module also converts the control instructions received from the display control board into input control signals and transmits them to the CPU processing module. This two-way conversion mechanism greatly enhances the compatibility and versatility of the system, making the control unit adaptable to different models and specifications of tube transmitters.

[0051] The power module ensures that each module of the entire control system can obtain stable and reliable power supply, thereby ensuring the continuous and stable operation of the system.

[0052] The software design of this PLC controller has high configurability. When the control unit needs to be applied to different transmitter systems, the operator only needs to adjust the specific acquisition signal definition. This adjustment process mainly involves parameter setting and logic definition at the software level, without the need to modify the hardware. For example, by modifying the address definition, signal type, sampling frequency, etc. in the PLC program, the control unit can correctly identify and process signals from a specific transmitter system. This versatility is reflected in the control unit's ability to easily adapt to electronic tube transmitter systems of different power levels, different operating frequencies, and different modulation modes.

[0053] The specific structure of the PLC controller of the general electronic tube transmitter in the embodiment of the present application is described in detail below. Please refer to Figure 2 The structure diagram of another PLC controller of a general electronic tube transmitter provided by the embodiment of the present application is shown in FIG. 6. Figure 2 The specific structure of the unit hierarchy contained in each module is shown in FIG. 6. The working principles of these specific structures are explained below.

[0054] In an alternative embodiment, Figure 2 The PLC switch quantity processing module in the embodiment includes a PLC switch quantity input unit and a PLC switch quantity output unit, wherein:

[0055] The PLC switch quantity output unit is connected with the CPU processing module and the electronic tube transmitter respectively, for receiving the output control signals sent by the CPU processing module, converting the output control signals into PLC control signals suitable for the electronic tube transmitter, and sending the PLC control signals to the electronic tube transmitter.

[0056] The PLC switch quantity input unit is connected with the CPU processing module and the display control panel respectively, for receiving the control instructions sent by the display control panel, converting the control instructions into the input control signals, and sending the input control signals to the CPU processing module.

[0057] The purpose of the PLC switch quantity output unit is to realize the signal conversion and transmission between the CPU processing module and the electronic tube transmitter. When the CPU processing module generates output control signals according to the system state and control logic, the PLC switch quantity output unit receives these signals and performs necessary signal conversion. The signal format generated by the CPU processing module may not completely match the control signal format required by the electronic tube transmitter. By converting the output control signals into PLC control signals suitable for the electronic tube transmitter, the PLC switch quantity output unit ensures that the control instructions can be correctly understood and executed by the transmitter. This signal conversion and adaptation mechanism greatly improves the compatibility of the system, so that the same set of PLC control units can be applied to electronic tube transmitters of different models and specifications, embodying the generality and flexibility of the system design.

[0058] The PLC switch quantity input unit is responsible for processing the signal flow from the display control panel to the CPU processing module. It is connected with the display control panel and the CPU processing module, and this connection configuration enables the control instructions input by the operator through the display control panel to be accurately transmitted to the core processing unit of the system. When the operator inputs control instructions through the display control panel, the PLC switch quantity input unit receives these instructions and converts them into input control signals that can be understood and processed by the CPU processing module.

[0059] Further, the PLC controller further comprises a relay control board, wherein:

[0060] The relay control board is connected with the PLC switch input unit and the display control board respectively, and is used for adjusting voltage level of the input control instruction.

[0061] The relay control board can receive and process input signals of different levels. When the operator inputs a control instruction through the display control board, the relay control board can adjust the voltage level of the instruction according to the high or low level logic. This adjustment ensures the compatibility of the input signal and the internal logic of the system. For example, if the system is designed to recognize a high level active signal, but a low level active instruction is input, the relay control board can convert it into a high level signal through internal circuit. At the same time, the PLC switch input unit can also be set to cooperate with this process. By configuring the PLC switch input unit, it can be defined how to interpret the received signal. This configuration may include setting the trigger mode of the input channel (such as rising edge trigger, falling edge trigger or level trigger), and defining which level state corresponds to the active state. In this way, even if the level characteristics of the input signal change, the system can correctly recognize and process these signals by adjusting the settings of the PLC switch input unit.

[0062] In an alternative embodiment, Figure 2 The signal acquisition module comprises a working state signal acquisition unit and an operation state signal acquisition unit, wherein:

[0063] The working state signal acquisition unit is connected with the CPU processing module and the electronic tube transmitter respectively, and is used for acquiring the defined address of each switch value of the electronic tube transmitter, to obtain the working state signal.

[0064] The operation state signal acquisition unit is connected with the CPU processing module and the electronic tube transmitter respectively, and is used for acquiring the operation state signal generated after the electronic tube transmitter executes the PLC control signal.

[0065] The main responsibility of the working state signal acquisition unit is to collect the defined addresses of each switch quantity of the tube transmitter, thereby obtaining the working state signal. This process is crucial for understanding the current running state of the transmitter. Specifically, there are multiple key switch quantities inside the tube transmitter, such as the power switch, power adjustment switch, frequency setting switch, etc., each with its specific address definition. The working state signal acquisition unit, through direct connection with the tube transmitter, continuously scans and reads the states of these switch quantities. Different models of transmitters may have different types and numbers of acquisition points, such as various door switches, cooling system states, overload protection, etc. To improve universality, the working state signal acquisition unit adopts a configurable address mapping mechanism. Specifically, the system allows adjusting the defined addresses of various switch quantities through a simple configuration process. This means that whether it is dealing with door switch states, cooling system operation, or overload protection trigger states, the system can accurately collect these information by adjusting the corresponding address definitions.

[0066] The operation state signal acquisition unit focuses on collecting the operation state signals generated after the tube transmitter executes the PLC control signals. This process is very important for verifying the execution effect of control instructions and monitoring the response of the transmitter. When the PLC control signals are sent to the tube transmitter, the transmitter will perform corresponding operations according to these instructions, such as adjusting power, switching frequency, or changing working mode, etc. The task of the operation state signal acquisition unit is to capture the actual state changes after these operations. For example, if the PLC control signal indicates to increase the output power, the operation state signal acquisition unit will collect the actual power output changes to confirm whether the instruction is correctly executed and how effective the execution is.

[0067] Further, the signal acquisition module further includes a signal processing unit, wherein:

[0068] The signal processing unit is configured to preprocess the working state signals and operation state signals collected from the tube transmitter.

[0069] During the operation of the tube transmitter, various acquisition quantities may have different characteristics and importance. Some signals may change rapidly, requiring high-speed sampling and processing; some signals may be subject to significant environmental interference, requiring special filtering processing; and some signals may require other forms of special processing to extract useful information.

[0070] For high-speed changing acquisition quantities, such as power fluctuations or some fast switch states, the signal processing unit can use high sampling rate and fast response processing algorithms. This may include using high-speed A / D converters combined with real-time digital filtering techniques to capture rapid changes in signals without losing important information.

[0071] For collected quantities that require filtering, such as analog signals affected by electromagnetic interference, the signal processing unit can select appropriate filtering algorithms based on the characteristics of the interference. For example, for low-frequency noise, a low-pass filter can be used; for strong random interference, more complex algorithms such as median filtering or Kalman filtering can be used. Certain collected quantities may require special mathematical processing. For example, for the output of a nonlinear sensor, linearization processing may be required; for periodic signals, Fourier analysis may be required to extract frequency information.

[0072] In an alternative embodiment, Figure 2 The PLC controller of the general electronic tube transmitter in the above embodiment further comprises a connector. The connector comprises a communication interface, an input interface, and an output interface, wherein:

[0073] The signal acquisition module is connected to the electronic tube transmitter through the communication interface and the input interface;

[0074] The PLC switch quantity processing module is connected to the electronic tube transmitter through the output interface.

[0075] The communication interface is designed to establish a data channel between the signal acquisition module and the electronic tube transmitter. This interface uses industrial standard communication protocols such as RS-485, Modbus, or Ethernet to ensure the reliability and compatibility of data transmission. Through this interface, the system can obtain various operating parameters of the electronic tube transmitter in real time.

[0076] The input interface is specifically used to receive various state signals and analog quantities from the electronic tube transmitter. This interface includes switch quantity signals (such as door switch status, emergency stop button status) and analog signals (such as current, voltage, temperature, etc. measurement values). The design of the input interface needs to consider the type, voltage level and isolation requirements of the signal to ensure accurate signal acquisition and safe operation of the system.

[0077] The output interface is a control channel between the PLC switch quantity processing module and the electronic tube transmitter. This interface is responsible for transmitting control commands from the PLC system to the various actuators of the transmitter. Specifically, it includes relay output, transistor output, or analog output, which is used to control various functions of the transmitter, such as start / stop, power regulation, frequency adjustment, etc.

[0078] Optionally, the connector further comprises a power interface, wherein:

[0079] The power module is connected to an external power supply through the power interface.

[0080] The power module is connected with an external working power source through the special power interface, and can perform power management, including voltage conversion, current distribution and power quality monitoring. This ensures that each part of the PLC controller can obtain the required stable power supply.

[0081] Specifically, please refer to Figure 3 An interface schematic diagram of a display control panel is provided for the embodiments of the application to specifically illustrate the display control panel in the application. Figure 3 The operate mode (OPERATE MODE) includes manual (MANUAL) and automatic (AUTO) mode selection, corresponding to the work mode selection switch. The plate delay release (PLATE DELAY RELEASE) component corresponds to the plate delay release button indicator light. The alarm (ALARM) is displayed as a red circle, corresponding to the buzzer function. The mode (MODE) provides more detailed operation mode selection, including manual, automatic, maintenance, etc. The power supply (POWERSUPPLY) displays different power supply states, such as line voltage, filament power supply, etc. The status (STATUS) includes the state indication of multiple subsystems, such as bias, high voltage, tuning, etc. The cooling (COOLING) displays the state of each component of the cooling system, such as the main pump, standby pump, water temperature, etc. The overload (OVERLOAD) indicates various possible overload conditions, such as reflected power, high-speed tripping, etc. The door interlock (DOOR INTERLOCK) displays the on-off state of each door and panel to ensure safe operation.

[0082] Specifically, the display control panel includes a work mode selection switch, a plate delay release button indicator light, a buzzer, and various level state indicator lights corresponding to the electronic tube transmitter.

[0083] The functions of the work mode selection switch and the plate delay release button indicator light remain unchanged, and they are respectively used for selecting different work modes of the transmitter and ensuring safe discharge of the high-voltage component. The buzzer continues to serve as an important part of the sound alarm system. The various level state indicator lights corresponding to the electronic tube transmitter are the most detailed and key part of the display control panel. For example, the various levels include control logic output state, control logic process state, door switch state, cooling system state, overload state, etc.
