Description

Technical Field

[0001] The present invention relates to a control system used in a master controller, and more particularly, to a master control system with user-defined input and output and a control method thereof. Background Art

[0002] The master controller (also known as the master switch) is mainly used in electrical transmission devices. It controls the output device by connecting and interrupting the contacts. It is often widely used in the control systems of various types of lifting machinery. The master controller includes a mechanism frame, an operating mechanism arranged on the mechanism frame, and a joystick arranged on the operating mechanism. The joystick is controlled by the operating mechanism to control the output device. However, in the control process, the existing master controller usually has only one set of input ports and output ports. During control, multiple master controllers need to be set up to achieve control of multiple devices. In complex environments, multiple controllers need to operate simultaneously, which greatly increases the difficulty of operation and the configuration cost of the controller. If the number of master controllers is reduced, it is necessary to synchronize the devices connected to the input and output ports of the master controller when switching the input device. Frequent plugging and unplugging of the ports will cause damage to the master controller and reduce the efficiency during processing, resulting in poor overall use effect. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a custom input and output master control system and a control method thereof having multiple input and output ports and capable of automatically controlling corresponding output devices according to input signals.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a master control system with customized input and output, comprising a signal acquisition port module: which is configured to access several signal types through multiple input ports;

[0005] Signal mapping module: configured to store the input signal of the signal acquisition module and output a control signal based on the input signal;

[0006] Control strategy generation module: It generates signal coding for output end execution through the output signal transmitted by the signal mapping module;

[0007] Communication module: It is electrically connected to the control strategy generation module and is used to transmit the signal code output from the control strategy generation module;

[0008] Output port module: It is configured to output control signals to different control devices through multiple output ports.

[0009] The present invention is further configured as follows: an impedance matching circuit is provided in the signal acquisition port module, a multiplexer, a photoelectric isolation unit and a signal detection unit are provided in the matching circuit, and the signal detection unit is used to identify the type of connected device according to the port voltage waveform.

[0010] Preferably, the multiplexer includes several terminal resistors, each of which has a different resistance value. The signal acquisition port is also provided with an analog signal identifier and a bidirectional TVS tube. The analog signal identifier is used to detect the voltage and current connected to the port, and identify the type of device connected to the port based on the voltage and current.

[0011] The present invention is further configured as follows: the signal mapping module includes a memory and a conversion channel electrically connected to the memory, the memory is used to record a preset signal conversion logic, and the conversion channel is used to output a corresponding control signal according to the signal conversion logic in the memory.

[0012] The present application also provides a control method for a master control system with customized input and output, wherein the control method includes controlling an output terminal device based on a signal type, and comprises the following steps: S1, applying a test voltage at a signal acquisition port;

[0013] S2. Detect the control system and judge the input signal of the input end based on the detection signal;

[0014] S3. The memory compares the input signal with the recorded signal conversion logic. If the current input signal is not stored in the memory, it is determined that the device currently connected to the signal acquisition port has not recorded it. The control system interrupts the connection with the current port and notifies the staff to detect the docking device. Conversely, if the current input signal is stored in the memory, it is determined that the device currently connected to the signal acquisition port has recorded it in the memory, and the input signal at the conversion channel control signal acquisition port is converted into a corresponding control signal.

[0015] S4, the control strategy generation module receives the converted control signal and generates a corresponding output terminal device according to the control signal;

[0016] S5. The control system detects the control device connected to the output port module according to the output end device corresponding to the current output signal. If the corresponding device is not detected to be connected to the output port module, the control system interrupts the signal and notifies the staff to detect the connected device. Conversely, if the output end device corresponding to the current output signal is connected to the output port module, it is determined that the current output signal can control the device at the output port module, completing the control process from the input end device to the output end device.

[0017] By adopting the above technical solution, the beneficial effects are as follows: 1. The present application forms an automatic judgment and control process of signal access-output control by setting a signal acquisition port module, a signal mapping module and an output port module in the control system. At the same time, the present application sets multiple groups of input and output ports, and detects and judges the input signal during the signal transmission process, so as to automatically match the control device of the input port and the execution device of the output port, effectively solving the compatibility problem caused by the access of multiple devices during use, and the control is reliable. At the same time, the signal acquisition port module is integrated with an impedance matching circuit and a multiplexer, which realizes the matching of each controller and actuator. Automatic identification, the signal mapping module can automatically store the conversion logic preset by the staff, so that the input signal can be automatically converted into the corresponding output signal according to the setting and transmitted to the correct output port through the control strategy generation module and the communication module. At the same time, the optoelectronic isolation unit and the bidirectional TVS tube arranged in the signal acquisition port ensure the stability of signal transmission. The above system allows the staff to control the access devices of the input and output ends by customizing the preset signal conversion logic in the memory, avoiding the data reconstruction cost required after switching the control system, reducing the risk caused by errors during operation, improving the efficiency of system configuration before work, and reducing the difficulty of operation.

[0018] 2. Furthermore, a multiplexer is provided in the signal acquisition port in the present application, and a plurality of terminal resistors are provided in the multiplexer. The terminal resistors can be set to have different resistance values ​​according to requirements. Specifically, the terminal resistors can have different currents after the test voltage is connected, and form voltage-current characteristic curves of different frequencies, so that the type of connected device can be judged, thereby accurately judging the connected device. At the same time, the analog signal identifier provided in the port can judge the waveform of the generated curve and further compare the identification signal. In addition, the photoelectric isolation unit can isolate the signal, enhance the anti-interference ability during the detection process, and improve the detection accuracy of the analog signal identifier. In addition, a bidirectional TVS tube can be provided in the port in the present application according to requirements, so that when the control system is connected to a strong control signal, it can withstand the impact of reverse voltage in a short time, provide overvoltage / surge protection for the control system, improve the compatibility range of the system, and improve the configuration efficiency.

[0019] 3. At the same time, by installing a memory in the signal mapping module and presetting the memory before configuring the control system, the conversion logic corresponding to different access signals is obtained, and the conversion channel can obtain the corresponding conversion logic according to the input signal feature word memory, and automatically match the conversion signal to the corresponding output port to form the optimal control logic. At the same time, the memory can automatically cut off the connection with the input port after detecting an unrecorded signal, thereby preventing logical conflicts caused by illegal device access. After the conversion channel continues the logical conversion, the input signal is adjusted to the exclusive code of the device. Each of the codes can adapt to different differentiated devices and can automatically switch strategies according to the user's input signal. The operation is simple and the control efficiency is high.

[0020] 4. In addition, in the process of controlling the control system, the control system can detect the signal of the device at the input port. After the input signal is detected, the input signal is detected through the memory. If the input signal detected is recorded in the memory, it is determined that the current device has not been preset by the staff, and the currently connected device is a new device. In order to avoid damage to the system, the access device needs to be disconnected and the staff is notified for maintenance. If the current device is a new device required for control, it is determined that the current access device is qualified and meets the processing requirements. The staff updates the logic in the memory so that the current input device can control the output end through the system. On the contrary, if the current device is an illegal device, it can effectively avoid the logic conflict caused by the device access, prevent damage to the device, improve the overall safety, enhance the anti-interference ability, and meet the safety requirements in the processing process.
