[0031] In the drawings, the sizes of layers, regions, elements and their relative sizes may be exaggerated for clarity. Like reference numerals denote like elements throughout.

[0032] It should be understood that when an element or layer is referred to as "on ...", "adjacent to ...", "connected to" or "coupled to" other elements or layers, it can be directly on, adjacent to, connected to or coupled to other elements or layers, or there can be intervening elements or layers. On the contrary, when an element is referred to as "directly on ...", "directly adjacent to ...", "directly connected to" or "directly coupled to" other elements or layers, there is no intervening element or layer. It should be understood that although the terms first, second, third, etc. can be used to describe various elements, components, regions, layers and / or parts, these elements, components, regions, layers and / or parts should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or part from another element, component, region, layer or part.

When used herein, the term "and / or" includes any and all combinations of the relevant listed items.

[0035] Figure 1 Schematic diagram of the structure of the workstation alarm system of the embodiment of the present application, as shown in Figure 1 As shown, the workstation alarm system of the embodiment of the present application includes a visual inspection device, a data conversion unit DTU, a remote terminal unit RTU, an alarm indication module and a power supply module; wherein the visual inspection device is used to collect images of the installation station to be monitored, and extract feature points based on the collected images, and determine whether the installation station is installed with corresponding parts based on the extracted feature points; if the corresponding parts are not installed at the installation station, an alarm message is generated; and the alarm message is sent to the DTU. In the embodiment of the present application, the visual inspection device can be implemented by an image recognition system. By taking images of the relevant installation stations of the installation equipment, and then performing object recognition on the taken images, it is determined whether the installation station is installed with corresponding parts. The installation equipment here can be any equipment such as automotive equipment, ship equipment and other mechanical equipment.

[0036] The DTU accesses the cloud service platform through the antenna system of the DTU, and sends the alarm information to the RTU corresponding to the installation station where the parts are not installed through the cloud service platform. In the embodiment of the present application, when it is determined that the corresponding parts are not installed at the installation station to be monitored, an alarm message will be generated, an alarm prompt will be given to the installer at the installation station, and the corresponding alarm message will be sent to the remote monitoring personnel, so that the remote monitoring personnel can also know which installation stations have missing parts.

[0037] In the embodiment of the present application, the DTU may include a DTU device body, an antenna and a power adapter; the DTU device body is electrically connected to the visual inspection device through the power adapter. In order to make the DTU smaller and to make the wireless communication effect of the DTU better, the antenna of the DTU in the embodiment of the present application may adopt a suction cup antenna. The power adapter may adopt a 12V power adapter.

[0038] The RTU receives the alarm information and sends an alarm instruction to the alarm indication module corresponding to the installation station where the part is not installed.

[0039] In the embodiment of the present application, the RTU includes an RTU device body and an antenna, and the RTU device body and the antenna are electrically connected.

[0040] The alarm indication module is used to receive the alarm instruction and output alarm indication information.

[0041] In the embodiment of the present application, the alarm indication module includes a remote alarm indication module and a detection station alarm indication module; the RTU is connected in series with the remote alarm indication module through a digital output interface (Digital Output, DO), and the RTU controls the on and off of the alarm light of the remote alarm indication module based on the alarm information of the visual detection equipment module to output the alarm information;

[0042] The detection station alarm indication module is electrically connected to the visual detection equipment module.

[0043] A power supply module is used to supply power to the RTU and the alarm indication module respectively.

[0044] In an embodiment of the present application, the RTU detects the response operation of the alarm indication information, and when it is determined that the alarm is eliminated, sends the indication information of the alarm elimination to the corresponding DTU through the cloud service platform; the visual detection device reads the indication information of the alarm elimination and determines that the remote communication is ended.

[0045] In the embodiment of the present application, the RTU detects the response operation of the alarm indication information, and when it is determined that the alarm has not been eliminated, sends a warning message to the visual inspection device, so that the corresponding inspection station alarm indication module outputs a warning message to remind the remote communication failure. Wherein, when the RTU determines that the signal is interfered or the power supply is unstable, it determines that the alarm has not been eliminated.

[0046] In an embodiment of the present application, the visual inspection device and the DTU are connected via a wired interface, and the visual inspection device supplies power to the DTU via the DTU.

[0047] In the embodiment of the present application, the alarm indication module can be implemented by an alarm lamp. As an implementation method, the alarm lamp outputs different colors to indicate the corresponding alarm information. The alarm indication module can also be implemented by a buzzer, etc. For example, the corresponding alarm information can be output by outputting buzzing sound signals of different frequencies. Or the corresponding alarm information can be output by outputting sound signals of different tones. In the embodiment of the present application, the specific implementation method of the alarm indication module is not limited.

[0048] Figure 2 Schematic diagram of the workstation alarm process of the embodiment of the present application, such as Figure 2The figure shows an example of the wireless remote communication system being used in a machine vision inspection system to monitor the installation station. The system sends the inspection results to the installation station corresponding to the missing parts in real time and triggers an alarm light to alert the relevant installers that a part is missing.

[0049] like Figure 2 As shown in the figure, when the visual inspection equipment detects that there are parts missing at the inspection station, such as installation station 1, installation station 2, and installation station 3. Send the command "The remote alarm light of installation station 1 / 2 / 3 is red" to the DTU via the USB cable. The DTU uses the cloud service platform to send the command to the RTU of the corresponding installation station through a wireless network such as a 4G network. The RTU receives the command and executes the command to make the corresponding remote alarm light red, and alert the staff at the installation station.

[0050] The RTU then performs a self-check of the alarm result. If the alarm is successfully executed, the RTU will communicate with the cloud service platform to return the return value of "normal execution of the command" to the DTU. Then the host computer reads the return value received by the DTU module and records this remote communication. A normal remote communication ends. In the embodiment of the present application, the host computer can be a visual inspection device, that is, the visual inspection device is used to complete the relevant monitoring of the installation station to be monitored.

[0051] If the alarm command is not executed normally due to signal interference, unstable power supply and other factors, the visual inspection equipment will write the "alarm light turns yellow" command into the serial port, causing the alarm light at the installation station to turn yellow, reminding the worker that there is a problem with the communication system, and make a supplementary report and send the alarm message again.

[0052] Figure 3 This is a flow chart of the implementation process of the workstation alarm system of the embodiment of the present application, such as Figure 3 As shown, the instructions of the visual inspection device are sent and received through the USB cable connected to the DTU module to realize the normal alarm and alarm result self-check function. The visual inspection device first detects its own serial port and initializes the serial port. If it fails to open or the initialization fails, the prompt message of serial port opening failure (Serial failed or Serial error) is output. After the serial port is initialized successfully, data access through the serial port can be realized by writing data to or reading data from the serial port, such as outputting relevant instructions to the DTU and receiving the execution results of the instructions through data interaction between the serial port and the DTU.

[0053] DTU sends instructions from the visual inspection equipment to the cloud server through its own wireless communication mechanism, that is, sends relevant instructions to the wireless communication receiving end of RTU through the cloud server. If the wireless communication unit of RTU can normally receive the alarm instruction, it will execute the alarm instruction and make the alarm light of the inspection station show red. If the wireless communication unit of RTU fails to normally receive the alarm instruction, the alarm light of the inspection station will show yellow.

[0054] After the staff installs the corresponding parts at the inspection station, the alarm light returns to normal through manual operation, and the DTU sends the information that the parts at the inspection station are installed normally to the visual inspection equipment through the cloud service platform.

[0055] like Figure 4 As shown, the local log records of the workstation alarm system are as follows: Figure 5 The figure shows the online log record of the wireless remote alarm system. The embodiment of the present application provides a basis for judging the stability of the workstation alarm system and the installation status of the on-site workers through the log record function.

[0056] like Figure 6 As shown, the background control function of the workstation alarm system of the embodiment of the present application can be used for online background control on a PC or mobile terminal to control the DTU module and the RTU module to send and receive signals from different ports, thereby realizing the background control of the on and off of the alarm light.

[0057] like Figure 7 As shown, the online status query function of the communication device of the workstation alarm system of the embodiment of the present application can query whether the communication device is online and the online and offline time in the background, and can monitor the communication status of the wireless remote communication system in real time.

[0058] It should be understood that the "in an embodiment of the present application" or "in some embodiments" mentioned throughout the specification means that specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in an embodiment of the present application" or "in some embodiments" appearing throughout the specification may not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. It should be understood that in various embodiments of the present application, the size of the sequence number of the above-mentioned processes does not mean the order of execution, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application. The above-mentioned sequence numbers of the embodiments of the present application are for description only and do not represent the advantages and disadvantages of the embodiments.

[0059] The methods disclosed in several method embodiments provided in this application can be arbitrarily combined without conflict to obtain new method embodiments.

[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
