Description

Technical Field

[0001] This invention relates to the field of motor control technology, and in particular to a control system and remote control operating system for a manual / automatic integrated motor. Background Technology

[0002] Traditional motor control systems suffer from problems such as complex switching between manual and automatic modes, poor stability of remote control, and weak anti-interference capabilities. Existing manual-automatic integrated motor systems are typically complex in structure, have low control precision, and lack effective fault diagnosis and emergency mechanisms. Especially in fields such as industrial automation and intelligent equipment control, higher demands are placed on the accuracy, reliability, and ease of remote operation of motor control.

[0003] Therefore, developing a simple, precise, and multi-mode manual / automatic integrated motor control system and remote control operating system has significant practical value. Summary of the Invention

[0004] The purpose of this invention is to provide a simple, precise, and multi-mode manual / automatic motor control system and remote control operating system.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] The present invention provides a control system for a manual-automatic motor, including a fixed base (1), a manual-automatic motor (2), a swing arm (3), a transmission rod (4), a controlled mechanism (5), and a cable (6).

[0007] The manual / automatic motor (2) is mounted on the mounting base (1) by screws;

[0008] The manual-automatic motor (2) has an output shaft (21) on its side. The output shaft (21) has a semi-circular cross-section structure and a swing arm (3) is installed on its output shaft (21).

[0009] Both ends of the transmission rod (4) are provided with connecting arms (43), and the adjusting screw (42) end of the connecting arm (43) is provided with adjusting nuts (41). The end of the transmission rod (4) away from the motor (2) is provided with a fixed lock (44), and the fixed lock (44) is connected to the controlled mechanism (5).

[0010] The cable (6) is installed at the tail end of the automatic / manual motor (2), and the other end is connected to the main unit.

[0011] This invention provides a remote control operating system for a manual / automatic motor, including remote control;

[0012] The remote control is divided into two control methods: wired control and wireless control.

[0013] The wired control is a short-distance control method. By connecting the remote control and the host with a wire, the control signal of the remote control is transmitted to the host. The remote control data is received through the communication interface inside the host. Then, the original control parameters are parsed through the protocol stack inside the host. Then, the host runs an algorithm through the main controller to convert the original parameters into the execution target value of the manual-automatic motor (2). According to the input signal type of the remote control actuator, the target value is converted into the corresponding electrical signal through the output interface module of the host, so that the motor chip can recognize the electrical signal output by the host and finally drive the manual-automatic motor (2) to operate. The operation of the manual-automatic motor (2) drives the swing arm (3) and the transmission rod (4) through the output shaft (21) to operate. Finally, the controlled rod (51) connected to the transmission rod (4) operates.

[0014] The wireless control is a long-distance control method. The main unit has a built-in wireless module, which connects the remote control and the main unit casing wirelessly.

[0015] In a WiFi-enabled environment, start the remote control. The remote control will detect the network environment and then establish a WiFi direct connection or AP mode. The data will be parsed and transmitted to the host via WiFi direct connection or AP mode. The host will then send an electrical signal that the motor chip can recognize to the motor chip via a data cable. The motor chip will then parse the signal and start the motor.

[0016] When WiFi is unavailable, the remote control data can be transmitted to the main unit by activating the 4G cellular network. The main unit then sends an electrical signal that the motor chip can recognize to the motor chip via a data cable. The motor chip then analyzes the signal to start the automatic / manual motor.

[0017] Furthermore, in the wireless control mode, when the remote control transmits the original command to the host, the host then processes it internally.

[0018] 1) Decryption / Verification;

[0019] 2) Kinematic solution;

[0020] 3) PID parameter fusion;

[0021] 4) Generate electrical signals that can be recognized by the motor chip.

[0022] Furthermore, in wireless control mode, when the 4G network is disconnected, the wireless module inside the host will cache the last valid command and restart after it is restored;

[0023] When the automatic / manual motor (2) suddenly malfunctions, the Hall sensor inside the automatic / manual motor (2) will return an error code.

[0024] Furthermore, the wireless module in the remote control and the main unit is ESP8266 + SIM7600CE, and the 4G module in the remote control and the main unit is SIM7600CE.

[0025] The beneficial effects of this invention are:

[0026] 1. The semi-circular cross-section output shaft is used in conjunction with the swing arm to improve power transmission efficiency and reduce energy loss;

[0027] 2. The transmission rod is equipped with a double adjusting screw structure with adjusting nuts at both ends, which facilitates precise adjustment of the transmission length and angle to meet the needs of different working conditions;

[0028] 3. Supports both wired and wireless control modes to meet diverse needs for precise short-distance control and flexible long-distance operation;

[0029] 4. In wireless control mode, it integrates three connection methods: WiFi direct connection, AP mode and 4G cellular network, to ensure stable control in various network environments;

[0030] 5. A complete signal processing flow (decryption / verification, kinematic calculation, PID parameter fusion) ensures control accuracy and response speed;

[0031] 6. It has a network outage caching mechanism and Hall sensor fault feedback function to improve system reliability and security;

[0032] 7. The modular design facilitates installation and maintenance, has strong expandability, and is suitable for multiple fields such as industrial automation and intelligent equipment. Attached Figure Description

[0037] The technical solutions provided by the present invention will be described in detail below with reference to the embodiments, but they should not be construed as limiting the scope of protection of the present invention.

[0038] Example 1: Control System Implementation

[0039] like Figure 1 As shown, the control system includes a fixed base 1, a manual / automatic integrated motor 2, a swing arm 3, a transmission rod 4, and a controlled mechanism 5. The manual / automatic integrated motor 2 is fixed to the fixed base 1 with high-strength screws to ensure operational stability. The output shaft 21 on the side of the motor adopts a semi-circular cross-section structure. This design ensures a reliable connection with the swing arm 3 while reducing rotational inertia. The swing arm 3 is fixed to the output shaft 21 with screws and rotates synchronously with the motor.

[0040] The transmission rod 4 has connecting arms 43 at both ends, and each connecting arm 43 has an adjusting nut 41 at the end of its adjusting screw 42. The length of the transmission rod can be precisely adjusted by rotating the adjusting nut 41. The distal end of the transmission rod 4 is bolted to the controlled mechanism 5 (such as a handle or operating lever) via a fixing lock 44. The cable 6 is led out from the tail end of the motor and connected to the control host for power supply and signal transmission.

[0041] Example 2: Wired remote control operation implementation

[0042] like Figure 3 As shown, in wired operation, the operator issues control commands via a wired remote control. The commands enter through the host communication interface and are parsed by the protocol stack to extract the raw control parameters (such as speed, direction, and displacement). The main controller runs a preset algorithm to convert the raw parameters into target values ​​for motor execution (such as PWM duty cycle and pulse frequency). The output interface module generates an electrical signal recognizable by the motor chip based on the command type (analog / digital), driving the motor to operate. The motor output shaft 21 drives the swing arm 3 to swing, which in turn drives the controlled lever 51 to the target position via the transmission rod 4.

[0043] Example 3: Implementation of Wireless Remote Control Operation

[0044] like Figure 3 As shown, during wireless control, the main unit utilizes a built-in ESP8266+SIM7600CE wireless module. In a WiFi environment, the remote control automatically detects the network and selects either WiFi Direct or AP mode to establish a connection; data is then parsed and transmitted to the main unit. When WiFi is unavailable, the SIM7600CE 4G module is activated, transmitting data via the cellular network. Regardless of the method, the data is ultimately converted into electrical signals recognizable by the motor chip to drive the motor.

[0045] The wireless control process includes:

[0046] 1) After receiving the original command, the host performs decryption and CRC verification to ensure data integrity;

[0047] 2) Perform kinematic calculations based on the mechanical structure parameters to convert the target position into motor rotation angle;

[0048] 3) Integrate PID control parameters to optimize dynamic response characteristics;

[0049] 4) Generate a comprehensive control word containing speed, direction, and position information, and send it to the motor chip.

[0050] Example 4: Fault Handling Implementation

[0051] When the 4G network is interrupted, the SIM7600CE module automatically caches the last valid instruction, and continues control according to the cached instruction after the network is restored. The automatic motor 2 has a built-in Hall sensor to monitor the operating status in real time. When abnormalities such as overcurrent, stall, or overheating are detected, an error code is immediately fed back to the host. The host takes measures such as speed reduction, shutdown, or alarm according to the error level.

[0052] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
