The cold chain display unit 12 is, for example, a display screen or a touch display screen for displaying various image frames. The cold chain operation interface 13 can be, for example, an operation interface such as a keyboard, a mouse, or a touch panel integrated in a screen, allowing users to input various commands and messages.

The mobile terminal device 2 is, for example, a portable electronic device such as a mobile phone or a tablet computer operated by an engineer, and includes a terminal control unit 21, a terminal camera unit 22 electrically connected to the terminal control unit 21, and an electrically connected on the terminal operation interface 23 of the terminal control unit 21 . The terminal control unit 21 is, for example, a control chip or a control circuit such as a processor or a microcontroller, and is used to control the overall operation of the mobile terminal device 2 . The terminal camera unit 22 is, for example, a camera lens module, which can be used to acquire external images or videos. The terminal operation interface 23 is, for example, a touch panel integrated in a display screen or an external input device, allowing users to input various commands or messages.

In the operation process of the control method of the present invention, when engineers need to control the refrigeration equipment 4, they can first operate the cold chain control device 1 to issue corresponding instructions. Therefore, in step S01 the cold chain control device 1 A control instruction for controlling the refrigerating equipment 4 will be received through the cold chain operation interface 13. The control instruction is about setting one of the operating temperature, time, power, and abnormal management of the refrigerating equipment 4, that is to say, the The control command is related to setting the operation state of the refrigeration equipment 4 or displaying abnormal information of the refrigeration equipment 4 . After the cold chain control unit 11 receives the control command through the cold chain operation interface 13, it will make the cold chain display unit 12 display a display screen corresponding to the control command, for the engineering personnel to perform subsequent operations.

In step S02, after receiving the control command, the cold chain control device 1 sends a barcode generation request corresponding to the control command to the server 3 according to the specific content of the control command.

In steps S03~S04, the server 3 will generate a barcode such as a QR barcode according to the barcode generation request, and send the barcode to the cold chain control device 1. The barcode includes connecting to URL information of different webpages of the server 3 . For example, when the control instruction is about setting the operation status of the refrigeration device 4, the URL information contained in the barcode is linked to a web page for verifying the control right line. Or, when the control instruction is about reporting the abnormality of the refrigeration device 4, the URL information contained in the barcode will be linked to a webpage for returning the abnormality report.

In step S05, the cold chain control device 1 receives a barcode generated by the server 3 according to the barcode generation request, and displays the barcode on the cold chain display unit 12 for engineering personnel to operate the mobile terminal device 2 Scan the barcode.

In steps S06-S07, when the engineer starts to scan the QR barcode displayed on the cold chain control device 1 through the mobile terminal device 2, the terminal camera unit 22 will generate a picture containing the barcode displayed on the cold chain display unit 12. barcode image, and the terminal control unit 21 of the mobile terminal device 2 analyzes the barcode image to obtain the website information. Then, the mobile terminal device 2 will connect to the corresponding webpage of the server 3 according to the website information, and establish a connection with the server 3 .

In step S08, the mobile terminal device 2 can further transmit at least one of a document data and a verification information to the server 3 according to the web page corresponding to the aforementioned operation instruction, so as to perform related processing operations. For example, when the control instruction and the webpage are about the abnormal status report of the refrigeration equipment 4, the content of the webpage displayed on the screen of the mobile terminal device 2 will present a column for filling in a message and a column for uploading a file. The document data sent by the mobile terminal device 2 from the webpage to the server 3 will include an image data showing the abnormal part of the refrigeration equipment 4 generated by the terminal camera unit 22 and a description of the refrigeration equipment 4. Text data in an abnormal state, and in this case, it is not necessary to send the verification information to the server 3 . In this way, engineering personnel can directly take images through the mobile terminal device 2 to report abnormalities and save data on the refrigeration equipment 4. The server 3 establishes a connection and can ensure that the mobile terminal device 2 performs related operations after being linked with the cold chain control device 1. Such a control mechanism can ensure that the engineering personnel report abnormalities at the merchant site, and can also It effectively prevents personnel (such as shop assistants) who do not hold the mobile terminal device 2 from performing related operations.

On the other hand, when the control command and the webpage are related to the operation state setting or management of the refrigeration equipment 4, the content of the webpage displayed on the screen of the mobile device in step S08 will show the administrator account number and administrator password. Fill in the message field, after the engineering staff completes the filling, the mobile terminal device 2 will send the verification information about the operation authority of the control command to the server 3, and the verification information includes the verification account information corresponding to the administrator account And the authentication password information corresponding to the administrator password.

In steps S09 and S10, after the server 3 completes the verification procedure of the verification information, it will send the verification result to the cold chain control device 1 . After the cold chain control device 1 receives the verification result, if the verification result is passed, the cold chain control device 1 can transmit the control instruction to the refrigeration equipment 4, so that the engineering personnel can start to operate on the cold chain control device 1 Start to inspect and control related parameters such as operating temperature and power of the refrigeration equipment 4 . According to the above verification process, it can be ensured that the cold chain control device 1 can only open the use authority to control the refrigeration equipment 4 after the interactive verification with the mobile terminal device 2, so that it can be ensured that the cold chain control device 1 can control The refrigerating equipment 4 is operated by the engineering personnel holding the mobile terminal device 2 instead of other personnel, so as to ensure that the operation process can be carried out correctly and avoid unnecessary mistakes.

Based on the above description, the control method of the present invention can ensure that the mobile terminal device 2 must scan the barcode displayed by the cold chain control device 1 to pass the authority verification of the server 3 to control the cold storage device 4 . The control of the cold storage equipment 4 by the cold chain control device 1 is carried out by the engineer holding the mobile terminal device 2 , so that unnecessary mistakes can be avoided during the control process. In addition, when the refrigeration equipment 4 fails or is abnormal, the engineering personnel can directly send the description of the abnormal condition and related images to the server 3 through the mobile terminal device 2, which can simplify the working time of the related process. Therefore, the control method of the cold chain control device 1 and the mobile terminal device 2 of the present invention can indeed achieve the purpose of the present invention.
