Description

Technical Field

[0001] The present invention belongs to the technical field of electromechanical technology, and in particular relates to a simulation and detection method based on the working conditions of an internal motor of a photoelectric radar. Background Art

[0002] Motors play an important role in modern facilities, equipment and devices. The transformation of the state or spatial position of some of its components is achieved through the electronic control of the motor. DC motors are widely used in equipment, facilities or equipment actuators due to their own advantages. In many cases, the rotation speed, rotation torque, rotation accuracy and rotation stability of the components have higher index requirements.

[0003] There are many types of photoelectric radars with a wide market distribution. The optical-mechanical components are important photoelectric components, among which the zoom and focus components are the core components, which are composed of an objective lens group, a fixed reflector, an eyepiece group, etc. The objective lens group includes a zoom mechanism, and the eyepiece group includes a focusing mechanism. Driven by the control component, the mechanism switches to a large field of view system after being inserted into the zoom element group, and switches to a small field of view system after exiting. The realization of these functions is precisely controlled by a DC brushed motor. A high-reliability control system is also particularly important for specific users or under specific environmental conditions. Market feedback information over the years has shown that the failure rate of motors is high, resulting in reduced product reliability, and it is difficult to deal with field maintenance, troubleshooting, or product evaluation and prediction. In the existing single-point testing method, the motor is installed in the equipment, and continuous impedance detection cannot be performed. Generally, a fixed-point measurement method is used, which is inefficient. Summary of the invention

[0018] like Figures 1 to 4 The simulation and detection method based on the working condition of the internal motor of the photoelectric radar is suitable for detecting the condition of the internal motor of the photoelectric radar. Preferably, the internal motor is a brushed motor. It includes a housing of the detection device, such as Figure 1 As shown, a power module 1, a controller 2, a terminal processing display 3 and a data acquisition processor 4 are arranged in the housing, wherein the power module 1 provides power to the controller 2, the terminal processing display 3 and the data acquisition processor 4 and can be connected to the motor in the photoelectric radar in a plug-in manner and provide power;

[0019] The controller 2 can communicate with the internal motor to control the working parameters of the motor, including the forward and reverse rotation of the motor, the rotation rate, etc. The data acquisition processor 4 collects the power supply voltage of the power module 1 to the internal motor and the real-time impedance of the internal motor, and can display it through the terminal processing display 3. The data acquisition processor 4 is electrically connected to the internal motor through the data cable 5. This method can realize the simulation and detection of the working condition of the motor, so as to inspect, accurately repair or evaluate and predict the working status of the motor for a period of time in the future. The simulation and detection methods include:

[0020] A speed regulator and a reversing switch are provided in the controller 2, and the speed regulator and the reversing switch are electrically connected to the internal motor respectively. The speed regulator and the reversing switch are used to control the speed of the internal motor from fast to slow or from slow to fast, and the reversing switch is used to control the forward and reverse rotation of the internal motor.

[0021] As a specific implementation method provided in this case, a jog switch 3 is provided in the controller 2, and the jog switch 3 is used to control the operation state of the internal motor to be turned off or on; the operator controls the working state of the internal motor according to the display value of the power supply voltage of the internal motor displayed on the terminal processing display 3, controls the speed of the internal motor through the speed regulator and the reversing switch, and controls the rotation of the internal motor through the reversing switch, including:

[0022] If the displayed value of the power supply voltage is less than 5V, the working voltage of the internal motor is interrupted and turned on at intervals of 5 seconds to 10 seconds, and the working condition parameters of the internal motor collected by the data acquisition processor 4 are displayed on the terminal processing display 3. Generally, simple manual recording is used as an initial detection;

[0023] If the terminal processing display 3 shows that the impedance of the internal motor is below 40Ω, it is considered that the internal motor is working normally and no detection is required;

[0024] If the terminal processing display 3 displays that the impedance of the internal motor is the first resistance value, and the first resistance value is within the range of 40Ω-200Ω, the display value of the power supply voltage is adjusted to 8V, and the operating parameters of the internal motor collected by the data acquisition processor 4 are displayed on the terminal processing display 3 as the second resistance value, and are manually recorded. If the second resistance value is less than the first resistance value, the internal motor is controlled to rotate forward and reverse three times respectively, and it is judged that if the third resistance value displayed on the terminal processing display 3 is less than 40Ω, then it is considered that the internal motor is working normally. If the third resistance value is greater than or equal to 40Ω, then it is considered that the internal motor is abnormal, and a signal feedback, such as sound or light display, is performed to perform maintenance or restore the initialization state;

[0025] Further, the speed of the internal motor is controlled by the speed regulator and the reversing switch, and the internal motor is controlled by the reversing switch.

[0026] If the terminal processing display 3 shows that the impedance of the internal motor is the fourth resistance value, and the fourth resistance value is greater than 200Ω, the display value of the power supply voltage is adjusted to 12V, and the terminal processing display 3 shows that the impedance of the internal motor is the fifth resistance value. If the fifth resistance value is greater than the fourth resistance value, the internal motor is controlled to rotate forward and reverse three to five times respectively, and the terminal processing display 3 shows that the impedance of the internal motor is the sixth resistance value. If the sixth resistance value is less than 40Ω, it is regarded that the internal motor is working normally. If the sixth resistance value is greater than or equal to 40Ω, it is regarded that the internal motor is abnormal, and signal feedback, such as sound or light display, is used for maintenance or restoration of the initialization state.

The speed control switch realizes fast and slow rotation of the motor, the reversing switch realizes forward and reverse rotation of the motor, and the inching switch realizes motor rotation and motor working conditions (360-degree rotation impedance distribution detection). Please refer to Figure 4 , part of which is a functional diagram of the terminal processing module. Figure 1 After reliable connection is completed, the machine is turned on in the default test state. The motor initially rotates to zero position 1, and the display unit displays the impedance value (optional voice broadcast); the normally open switch is in the rotating state, the switch is closed and the motor rotates to position 2, and the display unit displays the impedance value; 10 or more impedance values ​​are measured in sequence, and the single-chip microcomputer collects a set of data for processing and operation to display the position where the impedance value is particularly large and displays its average. This data is used to inspect, accurately repair or evaluate, and predict the working state of the motor for a period of time in the future (Note: during this rotation process, if the motor turns to the extreme position, it can be reversed to control the reverse rotation). The present invention adopts the brand ANENG-SZ08 display module to avoid the drawbacks of single-point testing using traditional methods, and the detection equipment and the DC motor under test are connected through a data cable 5 to realize the simulation and detection of the working condition of the motor, so as to inspect, repair or evaluate and predict the working state of the motor for a period of time in the future.
