[0002] Electrochromic devices are intelligent dimming devices. Taking electrochromic glass as an example, they can reversibly adjust transmittance under the influence of an electric field and are widely used in energy-saving windows in buildings, automotive sunroofs and side windows, and aircraft windows. To ensure that product performance meets design requirements, its optical information under different conditions must be accurately tested before leaving the factory to determine whether the product is qualified.

[0003] However, in the existing testing process, the state switching control and optical information detection of electrochromic devices still rely on manual, step-by-step operations. This operating mode not only affects testing efficiency but also makes it difficult to guarantee the consistency of test conditions and the repeatability of results, which is not conducive to large-scale, standardized quality control on the production line.

[0033] The terminal device 11 is used to send shift commands to the controller 12, send commands to the optical inspection device 13 to read optical information, and acquire optical information detected by the optical inspection device 13 based on the optical information commands. In actual use, the terminal device 11 is either communicatively or electrically connected to both the controller 12 and the optical inspection device 13.

[0034] Optionally, the shift command is used to adjust the gear position of the electrochromic device under test, so as to achieve color change of the electrochromic device under test. The control electrical signal can be a voltage signal or a current signal.

[0035] Optionally, the optical information reading command is a command to control the optical detection device 13 to perform optical information detection. The optical information includes transmittance, which is the ratio of the intensity of emitted light to the intensity of incident light after passing through the glass. The optical information may also include information such as the color and hue of the electrochromic device under test.

[0036] Among them, the electrochromic device can be an electrochromic film, electrochromic glass, a device that uses a PET film (Polyester Film) to sandwich an electrochromic film, or other color-changing devices with an electrochromic film sandwiched in them.

[0037] Among them, terminal device 11 can be a computer or host computer, etc.

[0038] The automatic testing system 1 for electrochromic devices according to this application includes a terminal device 11, a controller 12, and an optical detection device 13. In actual use, the controller 12 is electrically connected to the electrochromic device under test. The controller 12 can output control electrical signals corresponding to shift commands to the electrochromic device under test and control the electrochromic device under test to change color.

At the same time, the terminal device 11 is connected to both the controller 12 and the optical detection device 13. The terminal device 11 can send shift commands to the controller 12, send commands to the optical detection device 13 to read optical information, and acquire the optical information detected by the optical detection device 13 based on the optical information commands.

[0039] Therefore, the automatic testing system 1 for electrochromic devices in this application embodiment, through the control of the controller 12 and optical inspection equipment 13 by the terminal device 11, can realize the integration and automation of signal control and optical measurement during the optical information detection process of the electrochromic device under test, thereby improving production efficiency and reliability. Furthermore, the automatic testing system 1 for electrochromic devices in this application can achieve fully automated closed-loop testing, improving detection efficiency, ensuring the consistency of test conditions and the repeatability of results, which is beneficial for large-scale, standardized quality control on the production line.

[0040] See Figure 2 As shown in the figure, another automatic testing system 1 for electrochromic devices provided in this application embodiment further includes a signal processing unit 14, which includes a signal converter 141 and a signal integrator 142. The signal converter 141 is electrically connected to the signal integrator 142 and the controller 12 respectively; the signal converter 141 is used to convert the signal type of the controller 12 to the signal type of the signal integrator 142; the signal integrator 142 is electrically connected to the optical inspection device 13 and the terminal device 11 respectively.

[0041] Signal integrator 142 is used to integrate the signals of signal converter 141 and optical inspection equipment 13 for signal transmission to terminal equipment 11 through the same port of signal integrator 142.

[0042] Optionally, the signal converter 141 can convert the shift command of the RS485 signal sent by the terminal device 11 into a LIN signal that can be recognized by the controller 12, and then send it to the controller 12. The RS485 signal and the LIN signal are two different signal types.

[0043] Optionally, the terminal device 11 sends a command to read optical information in the form of an RS485 signal. The optical inspection device 13 transmits the optical information of the electrochromic device under test to the terminal device 11 in the form of an RS485 signal through the signal integrator 142.

[0044] It is conceivable that the terminal device 11 sends the optical information reading command in the form of LIN signal, RS422 signal, RS485 signal, CAN signal or RS232 signal, and the signal converter 141 can convert the shift command into a CAN signal or LIN signal that the controller 12 can recognize.

[0045] Specifically, signal converter 141 is used for data type conversion to enable data recognition between different devices. Signal integrator 142 can integrate signals from at least two devices onto the same port output.

[0046] See Figure 3 As shown, this application provides an embodiment of an automatic testing system for electrochromic devices and a schematic diagram of the electrochromic device under test. Figure 3 As shown, the electrochromic device under test includes electrochromic device under test 1, electrochromic device under test 2 to electrochromic device under test n. Embodiments of this application can test multiple electrochromic devices under test. (See reference...) Figure 3 As shown, the automatic testing system 1 for electrochromic devices also includes a scanning device 15.

[0047] The scanning device 15 is electrically connected to the signal processing unit 14. The scanning device 15 is used to scan the number of at least one electrochromic device under test, obtain the encoded information, and transmit the encoded information to the signal processing unit 14. The terminal device 11 is used to acquire the encoded information of at least one electrochromic device under test.

[0048] Optionally, the scanning device 15 is electrically connected to the signal integrator 142, and the signal integrator 142 transmits signals to the terminal device 11.

[0049] Furthermore, the signals of the signal converter 141, the optical inspection device 13, and the scanning device 15 are integrated to transmit signals to the terminal device 11 through the same port of the signal integrator 142, that is, the signal integrator 142 integrates the signals of the three input ports into one output port.

[0050] Optionally, the scanning device 15 can scan the QR code of the electrochromic device under test to obtain the encoded information, and send it to the terminal device 11 via the signal integrator 142 using an RS232 signal to input the encoded information of the electrochromic device under test. Here, RS232 is the signal type.

[0051] It is conceivable that the scanning device 15 can also use RS422 or RS485 signals to send the encoded information to the terminal device 11 through the signal integrator 142.

[0052] Optionally, the scanning device 15 is a movable scanning gun; or, the scanning device 15 is a fixed scanning gun located on one side of the conveyor belt that transports the electrochromic device to be tested.

[0053] In this application, the information corresponding to the electrochromic device under test is stored by establishing a corresponding mapping relationship through encoded information.

[0054] In some embodiments, the controller 12 includes at least two output channels, each of which is electrically connected to an electrochromic device.

[0055] The terminal device 11 is used to acquire the detection strategy of each electrochromic device under test, and sends shift instructions to the controller in sequence based on the gear information of each gear in the detection strategy.

[0056] The controller 12 is used to output a control electrical signal of the corresponding gear to the electrochromic device under test according to the gear shifting command, so as to make the electrochromic device under test change color.

[0057] Optionally, the gear information is used to indicate the gear that needs to be shifted. The controller 12 can output voltage or current at different gear levels to the electrochromic device under test so that the electrochromic device under test reaches the corresponding gear level.

[0058] In some embodiments, the terminal device 11 is used to acquire the detection strategy of each electrochromic device under test, and send shift instructions to the controller 12 in sequence based on the shift sequence information and the gear information of each gear in the detection strategy.

[0059] The controller 12 is used to control each output channel to output corresponding control electrical signals to each electrochromic device under test simultaneously or sequentially based on each shift command.

[0060] Optionally, the shift sequence information is used to shift the electrochromic device under test according to a predetermined shift sequence. For example, the shift sequence information includes the internally set shift sequence 3 → 1 → 5 → 1.

[0061] Specifically, the electrochromic device can have 5 levels, from level 1 to level 5. The transmittance of the electrochromic device gradually increases, with level 3 being the intermediate state, i.e., the steady state. In the embodiment of this application, the color-changing effect of level 3→1→5→1 is: normal-dark-bright-dark. However, during the testing process, the actual sequence of changes in the level of the electrochromic device under test is: level 3→2→1→2→3→4→5→4→3→2→1.

[0062] In some embodiments, the optical inspection device 13 includes at least two inspection components, each of which is configured to correspond to an electrochromic device under test.

[0063] The terminal device 11 is used to determine the electrochromic device under test that has completed the shift based on the output channel corresponding to the shift completion command returned by the controller 12 for each gear position, determine the target detection component from each detection component based on the electrochromic device under test that has completed the shift, generate an optical signal reading command corresponding to the target detection component, and send the optical signal reading command to the optical detection device 13. The optical inspection device 13 is used to control the target inspection component to inspect the electrochromic device under test based on the optical signal reading command, and return the optical information of the detected position to the terminal device 11.

[0064] Optionally, the detection component includes a light source and a detector, which are located on both sides of the corresponding electrochromic device under test, in order to detect the optical information of the electrochromic device under test.

[0065] The terminal device 11 in this embodiment can determine that the shift is complete when it receives the shift completion instruction returned by the controller 12. Then, through the output channel corresponding to the returned shift completion instruction, it can determine the electrochromic device under test that has completed the shift. This allows the optical detection device 13 to perform optical information detection through the target detection component corresponding to the electrochromic device under test that has completed the shift, thereby improving detection efficiency.

[0066] In practical applications, the embodiments of this application may involve simultaneously or sequentially switching each electrochromic device under test to the same gear, performing optical information detection on each electrochromic device after the gear switch is completed, and then simultaneously or sequentially switching each electrochromic device under test to the next gear and continuing to perform optical information detection on each gear until all electrochromic devices under test have completed optical detection at each gear, thereby improving detection efficiency.

[0067] In this embodiment, each electrochromic device under test can be sequentially switched between gears. After optical information detection is performed on each gear of each electrochromic device under test, optical information detection is performed on each gear of the next electrochromic device under test.

[0068] The controller 12 in this embodiment can control multiple EC (Electrochromic) devices. These EC devices can change color simultaneously or sequentially. For example, the terminal device 11 can control the EC glass to change color sequentially, but since the control interval is on the order of milliseconds, the actual effect is equivalent to controlling the EC glass to change color simultaneously.

[0069] In some embodiments, the controller 12 is configured to send shift status information for the electrochromic device under test that is shifting gears to the terminal device 11 when it receives a shift command; Terminal device 11 is used to update and display the current status of the electrochromic device under test based on the shift status information.

[0070] Optionally, in this embodiment of the application, the controller 12 obtains the shift status information of the electrochromic device under test that is shifting gears, so that the terminal device 11 can update and display the current status of the electrochromic device under test to view the current status of the electrochromic device under test.

[0071] In some embodiments, the terminal device 11 is used to determine whether the electrochromic device under test is qualified based on the preset threshold of the gear corresponding to the optical information and the shift command.

[0072] Optionally, based on the preset threshold of the gear corresponding to the optical information and the shift command, the quality of the electrochromic device under test is determined, including: determining the test result based on the preset threshold of the gear corresponding to the optical information and the shift command, and displaying the test result; the test result is used to indicate whether the electrochromic device under test is qualified.

[0073] As an example, optical information includes transmittance. Level 3 corresponds to two preset transmittance thresholds of 2% and 3%. If the transmittance is greater than 2% and less than 3%, then Level 3 of the electrochromic device under test is qualified. Level 1 corresponds to a preset transmittance threshold of 1.5%. If the transmittance is less than 1.5%, then Level 1 of the electrochromic device under test is qualified. Level 5 corresponds to a preset threshold of 4%. If the transmittance is greater than 4%, then Level 5 of the electrochromic device under test is qualified.

[0074] If the electrochromic device under test passes all three levels (3, 5, and 1), then the electrochromic device under test is deemed to be qualified.

[0075] The automatic testing system 1 for electrochromic devices in this embodiment integrates automatic gear shifting, automatic optical information detection, barcode scanning and encoding, and automatic association to form a test record. It supports simultaneous testing of multiple electrochromic devices, improving production efficiency. Furthermore, the automatic testing system 1 integrates three independent devices ("controller 12", "optical inspection device 13", and "scanning device 15") through a signal processing unit 14, enabling them to operate according to a pre-defined logic and generate records.

[0076] The working principle of the automatic testing system 1 for electrochromic devices in this application includes: (1) The automatic testing system 1 for electrochromic devices in this application includes a terminal device 11, an optical detection device 13 and a scanning device 15, which, together with a signal converter 141, a signal integrator 142 and a controller 12, can detect the optical information of multiple electrochromic devices under test.

[0077] (2) By sending different shift commands through the terminal device 11, the controller 12 can output different voltage levels to multiple electrochromic devices under test simultaneously or sequentially, thereby realizing the unified color change of multiple electrochromic devices under test, which is convenient for batch testing.

[0078] (3) The encoded information obtained by the scanning device 15 is sent to the terminal device 11 via RS232 communication. The signal converter 141 converts the shift command (carrying gear information) of the RS485 signal sent by the terminal device 11 into a LIN signal that the controller 12 can recognize. The LIN signal of the controller 12 (carrying shift status information indicating that shifting is in progress and shift completion command indicating that the set gear has been reached) is converted into an RS485 signal and transmitted to the terminal device 11 for synchronous display by the terminal device 11.

[0079] See Figure 4 As shown, this application provides a flowchart of an automatic detection method for electrochromic devices. The automatic detection method for electrochromic devices in this application can be applied to the automatic testing system 1 for electrochromic devices in this application, such as...

[0081] Optionally, the automatic detection method for electrochromic devices in this application embodiment can be executed by the terminal device 11.

[0082] Among them, the gear information is used to indicate the gear that needs to be shifted. Each electrochromic device under test can detect the optical information of at least two gears according to the detection strategy.

[0083] S402. Based on the gear information of each gear, shift commands are sent sequentially to the controller 12, so that the controller 12 outputs control electrical signals of different gears to the electrochromic device under test based on the shift commands, so as to make the electrochromic device under test change color.

[0084] Optionally, the controller 12 can output different levels of voltage or current to the electrochromic device under test so that the electrochromic device under test reaches the corresponding level.
