[0011] The preferred embodiments of the present application are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present application can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present application.
[0012] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
[0013] The technical solution of the present application can be applied to real-time monitoring of items on a conveyor belt. For example, an industrial encoder or terminal device sends a control command to an industrial camera to enable the industrial camera to capture images of the items. The industrial camera simultaneously sends a laser control command to an industrial laser to illuminate the items for image capture. This ensures that the recognition rate and acquisition accuracy of the industrial camera for image capture are improved, allowing the industrial camera to better adapt to weak light and dark environments.
[0014] Figure 1 The specific implementation of a structured light signal isolation protection adapter of the present application is shown. In this specific implementation, the structured light signal isolation protection adapter of the present application mainly includes: an industrial encoder interface. This module is mainly used to connect to an industrial encoder and receive an industrial camera control signal sent by the industrial encoder.
[0015] In this specific embodiment, the pulse control signal generated by the industrial encoder is transmitted through the industrial encoder interface. Exemplarily, items are placed on a conveyor belt for transporting items at certain time intervals. Each item has its own length, width and height. When the items are placed on the conveyor belt for transporting items, the reading of the items of the industrial encoder installed on the conveyor belt is recorded, and the reading of the industrial encoder when the items are transported on the conveyor belt is tracked. When the reading of the industrial encoder reaches a predetermined threshold, the industrial encoder sends an image acquisition control signal to the industrial camera to enable the industrial camera to take a picture. For example, the industrial encoder starts counting from zero, and when the conveyor belt moves forward a unit distance, the industrial encoder increases the unit count until the industrial encoder reading reaches the maximum value, and the industrial encoder can be reset and count again from zero.
[0016] exist Figure 1 In the specific implementation shown, the structured light signal isolation protection switching device of the present application further includes: a first photoelectric isolation module. The module is mainly used to connect with the industrial encoder interface to perform photoelectric isolation on the industrial camera control signal.
[0017] In this specific implementation, the first photoelectric isolation module drives the light emitting diode (LED) with the input industrial camera control signal, causing it to emit light of a certain wavelength, which is received by the photodetector to generate photocurrent, which is output after further amplification to complete the electrical-optical-electrical conversion, thereby playing the role of input, output, and isolation.
[0018] In this specific implementation, by connecting the first isolation module to the industrial encoder and the industrial camera respectively, one-way signal transmission can be achieved, the input end and the output end are electrically isolated, and the output signal has no effect on the input end, thereby achieving the purpose of precise voltage stabilization, thereby realizing the protection of the industrial camera and extending the service life of the industrial camera.

This module is mainly used to connect to the first photoelectric isolation module and the industrial camera respectively, receive the photoelectrically isolated industrial camera control signal and send it to the industrial camera, and receive the laser control signal sent by the industrial camera according to the photoelectrically isolated industrial camera control signal.
[0020] For example, the industrial camera receives an image acquisition control signal from an industrial encoder and starts to acquire images. Alternatively, the industrial camera receives an image acquisition control signal sent by a mobile terminal and starts to acquire images. At the same time, in order to ensure the recognition rate and acquisition accuracy of the industrial camera for image acquisition, the industrial camera sends a laser control signal at this time to irradiate the industrial laser onto the items on the conveyor belt.
[0021] exist Figure 1 In the specific implementation shown, the structured light signal isolation protection adapter of the present application further includes: a laser control signal conversion module. The module is mainly used to connect with the industrial camera interface to convert the laser control signal into a control signal acceptable to the industrial laser.
[0022] In this specific implementation, with the introduction of low-voltage logic, the problem of inconsistent input / output logic often occurs within the system, and the problem of conversion between the two levels needs to be solved first. At this time, a laser control signal conversion module is required.
[0023] In a specific embodiment of the present application, the laser control signal conversion module converts the laser control signal into an acceptable control signal through level conversion and / or logic inversion.
[0024] In this specific embodiment, the original laser control pulse laser voltage signal generated by the industrial camera is converted into a 3V level reverse pulse laser voltage signal by the laser control signal conversion module. The laser control signal is converted into a control signal acceptable to the industrial laser, so that the industrial laser can work normally.

The module is mainly used to connect with the industrial laser interface to convert the laser current signal into a laser voltage signal.
[0028] In this specific implementation, the laser current detection module detects the laser current signal when the industrial laser is working, and converts the laser current signal into a weak laser voltage signal for output.
[0029] exist Figure 1 In the specific implementation shown, the structured light signal isolation protection switching device of the present application further includes: an amplifier module. The module is mainly used to connect with the laser current detection module to amplify the laser voltage signal by a predetermined multiple and output it.
[0030] In this specific implementation, the amplifier module amplifies the weak laser voltage signal by a predetermined multiple to convert it into a strong laser voltage signal. Preferably, the predetermined multiple is 2 times, that is, the weak laser voltage signal is output after being amplified at two stages.

The module is mainly used to connect with the amplifier module, and output a pulsed laser voltage signal of laser intensity according to the laser voltage signal amplified by a predetermined multiple and a preset voltage.
[0032] In this specific implementation, the comparator module compares the laser voltage signal amplified by a predetermined multiple with a preset voltage, and outputs a PWM (Pulse Width Modulation) signal.

This module is mainly used to connect with the comparator module to output the pulsed laser voltage signal of the laser intensity to the LED display panel.
[0034] In this specific implementation, a pulsed laser voltage signal of laser intensity is output to an LED display panel, and the LED display panel can be used to determine whether the industrial laser emits laser light. Exemplarily, when there is a pulsed laser voltage signal of laser intensity, the LED display panel can display a red light, indicating that there are items on the conveyor belt at this time. When there is no pulsed laser voltage signal of laser intensity, the LED display panel can display a yellow light, indicating that there are no items on the conveyor belt at this time, thereby achieving real-time monitoring of the items on the conveyor belt.
[0035] In a specific embodiment of the present application, the structured light signal isolation protection adapter of the present application further includes: a second photoelectric isolation module. The module is mainly used to connect to the industrial camera interface and the LED display panel interface respectively, to perform photoelectric isolation on the status operation indication signal of the industrial camera received through the industrial camera interface, and to output the photoelectrically isolated status operation indication signal to the LED display panel through the LED display panel interface.
[0036] In this specific embodiment, the second photoelectric isolation module drives the light emitting diode (LED) with the input industrial camera status operation indication signal, causing it to emit light of a certain wavelength, which is received by the photodetector to generate photocurrent, and then output after further amplification to complete the electrical-optical-electrical conversion, thereby playing the role of input, output, and isolation.
[0037] In this specific embodiment, by connecting the second isolation module to the industrial encoder and the industrial camera respectively, unidirectional signal transmission can be achieved, the input end and the output end are electrically isolated, and the output signal has no effect on the input end, thereby achieving the purpose of precise voltage stabilization, thereby further realizing the protection of the industrial camera and extending the service life of the industrial camera.

[0041] The second power conversion module converts the predetermined DC power into a DC power of a second voltage and outputs it to the industrial laser through the industrial laser interface. Preferably, the first voltage is 5V and the second voltage is 3V.
[0042] In this specific embodiment, by setting up the first power conversion module and the second power conversion module, the higher voltage external power source is converted into a lower working voltage suitable for the corresponding working module, so as to ensure the normal operation of the corresponding working module while avoiding the problem of high power consumption caused by high voltage, thereby reducing the power consumption of the structured light signal isolation protection adapter. In addition, because the working voltages of different modules are different, by setting up the power conversion module, a preset DC power supply can be used to power different working modules, and then when designing the structured light signal isolation protection adapter, only one preset DC power supply is needed, thereby reducing the occupied space of the structured light signal isolation protection adapter.
[0043] The present application connects the first isolation module to the industrial encoder and the industrial camera respectively, so as to realize one-way signal transmission, electrically isolate the input end from the output end, and have no effect on the input end, thereby achieving the purpose of precise voltage stabilization, thereby protecting the industrial camera and extending the service life of the industrial camera. At the same time, the industrial camera is used to control the industrial laser, so that the industrial laser can be emitted in poor light conditions, thereby improving the recognition rate and acquisition accuracy of the industrial camera for image acquisition, and enabling the industrial camera to better adapt to weak light and dark environments.
