Description

A date verification method for carbon dioxide laser

Technical field

The present invention relates to the field of verification, and more particularly to the field of use date verification for carbon dioxide lasers.

Background technique

With the wide application of CO2 lasers, deepening of global economic trade, and increasing production costs, CO2 laser tube manufacturers and customers have put forward higher requirements for after-sales service of CO2 lasers. It is required to effectively control the after-sale time of each CO 2 laser tube.

The existing CO2 laser tube does not have a corresponding after-sales electronic key. The warranty start date can only be remembered from the factory time. After the fixed warranty time, it is the warranty deadline. After the warranty deadline, the CO2 laser tube cannot be sold after-sales warranty. This form of warranty does not meet the customer's needs because the machine tool builder and the middleman need inventory during the warranty period and cannot be installed and used immediately, and the inventory time is often as long as several months. Another reason is that the transit time and customs clearance time of multinational sales is relatively long. Due to the existence of these times, there is no guarantee that the initial use time of each CO2 laser tube will be precisely controlled. The warranty time can only be calculated by multi-party caliber. This method is inaccurate and the high moral hazard has a great impact on the manufacturer. This problem directly affects the operation of manufacturers, machine tool manufacturers and end customers.

Existing CO2 lasers do not have a means to record their time of use, and manufacturers cannot accurately record the initial usage time of each CO2 laser tube, so that the after-sales expiration date of each CO2 laser tube cannot be calculated.

Summary of the invention

In view of the problems and deficiencies of the above prior art, the present invention provides a method for verifying the date of use of a carbon dioxide laser, which realizes verification of the first use time of the carbon dioxide laser, and simultaneously realizes anti-counterfeiting verification, which can be used for CO2 laser after-sales warranty service

The method for verifying the date of use of the carbon dioxide laser according to the present invention comprises: the carbon dioxide laser generates a set of n passwords by scanning the two-dimensional code of the product label at the factory to be stored in the database of the server and simultaneously writing the storage of the electronic key. Zone (n is a natural number greater than 1). When the CO2 laser needs to be used, the sensor generates a signal after the electronic key is removed from the laser. The microprocessor freezes the date on the same day according to the signal condition and displays the date to generate a password. When the user uses WeChat or other QR code scanning software to scan the QR code on the label of the laser body, it will jump to the verification center website and display the product number, date and other information of the product, the user is on the webpage. Enter the date password on the electronic key and submit the activation. The server verifies whether the password is valid. The server searches and locates the database according to the password and tube number submitted by the user (the tube number is automatically read according to the scanned QR code). The sequential position of the password, such as a legal password, determines that the date corresponding to the password is a laser product. The start of the warranty date, if you enter the wrong password multiple times, the laser tube will default to the warranty date after the M day of the factory date.

Compared with the prior art, the invention has the beneficial effects of realizing the verification of the first use time of the carbon dioxide laser and realizing the anti-counterfeiting verification, and can be used for the carbon dioxide laser after-sales warranty service.

detailed description:

The invention will be further described in conjunction with the specific embodiments and the accompanying drawings, but should not be construed as limiting the scope of the invention.

As shown in FIG. 1, a usage date verification method for a carbon dioxide laser includes: a carbon dioxide laser generates a N-group password by scanning a QR code of a product label at a factory, and stores the data in a server database while writing an electronic key storage. Zone (N is a natural number greater than 1). When the CO2 laser needs to be used, the sensor generates a signal after the electronic key is removed from the laser. The microprocessor freezes the date on the same day according to the signal condition and displays the date to generate a password. When the user uses WeChat or other QR code scanning software to scan the QR code on the label of the laser body, it will jump to the verification center website and display the product number, date and other information of the product, the user is on the webpage. Enter the date password on the electronic key and submit the activation. The server verifies whether the password is legal. If it is a legal password, the date corresponding to the password is the start warranty date of the laser product. The server submits the password and the number according to the user. (The tube number is automatically read according to the scanned QR code), and the matching is found in the database. The ordinal position of the password; If you enter an incorrect password multiple times, the laser tube is a default days after the date of manufacture M is the warranty start date.

When the user verifies the password by inputting the electronic key on the webpage, if the webpage can display the correct product information, the laser is proved to be genuine, and vice versa.

As shown in FIG. 2, the carbon dioxide laser electronic key includes a battery and its power management module, an LCD display, a sensor module, a microprocessor unit, and a communication port. The battery and its power management module are responsible for powering each module in the electronic key. As shown in Figure 6, the LCD display is used to display the date password, and the sensor module is used to sense whether the electronic key is separated from the laser. The sensor module will According to its connection state with the carbon dioxide laser, a corresponding status signal is generated and transmitted to the microprocessor, and the communication port is used to realize communication between the microprocessor unit and the external module, and the microprocessor unit receives the status signal and drives the LCD display to correspondingly The date password is displayed. The sensor module may be an optical sensor, a switch type sensor or the like. The microprocessor unit also contains internal data storage, timers, peripheral circuits, and the like.

The working principle of the carbon dioxide laser electronic key is to first set the working date of the electronic key, encrypt the date and store it in the internal data storage area of the microprocessor, and set the timer to one cycle. Install the electronic key to the light exit of the factory-made CO2 laser and activate the electronic key. After the key is started, after the timer works for one day, the microprocessor automatically reads the date of the next day and encrypts it to generate a password. The microprocessor then drives the LCD display through the driver module to display the password. If the electronic key is not removed from the laser, the microprocessor will continue to work until the last day. After the working date is completed, the internal data will be cleared and a specific code will be displayed, indicating that the laser is not being used within the maximum time allowed. The artificially specified warranty start date is calculated from the date the laser was purchased or some other specific date.

When the customer first uses a carbon dioxide laser, the carbon dioxide laser must be separated from the carbon dioxide laser outlet by the electronic key installed in the carbon dioxide laser outlet (as shown in Figure 3), otherwise the electronic key will be burned. No after-sales warranty. When the electronic key is removed from the laser, the sensor will generate a corresponding signal. The microprocessor will freeze the date on the same day according to the signal condition, and display the date generation password. If the electronic key is in working time, the carbon dioxide will be displayed. The password generated by the laser start date is displayed all the time and the other data is cleared.

After-sales phase: Users can use the company's after-sales software for after-sales service based on different passwords generated by the electronic key.

The specific implementation manner is: first, set the number of working days of the electronic key to be M, then generate M n-bit passwords, and each password is not repeated. The M n-bit passwords are downloaded to the internal data storage area in the microprocessor through the communication port. The timer is set to one cycle per day, and the microprocessor updates the password in the order of the timer. The electronic key always displays the password for the date in the corresponding state within M days.

When the electronic key is downloaded, the assembly is automatically detected. As shown in Figure 4, when the electronic key is assembled with the CO2 laser, the sensor module of the electronic key generates a signal to the microprocessor that the microprocessor will no longer accept the assembly signal. The electronic key then updates the password every day from the first password until M days are completed. If the electronic key is separated from the CO2 laser within M days (that is, when the user first uses the laser), the sensor module will generate a working signal to the microprocessor when it is separated. After the microprocessor confirms that the signal is correct, the password of the day will be X (for example, password X is the Nth of M) records and keeps displaying until M day is over, and other passwords are all cleared after determining that the work signal is correct.

Then we can calculate the number of days that the CO2 laser will go through the first time from the factory to the customer for N days (the password of the electronic key is X), because the M n-digit passwords of each CO2 laser are different, the customer can Accurate and accurate after-sales service can be carried out based on the password generated by the electronic key and the number of the CO2 laser.

As shown in Figure 4, after the electronic key is assembled to the light-emitting end of the carbon dioxide laser, the contact surface of the electronic key sensor module is connected to the light-emitting end of the laser, and the sensor generates a signal (which may be a pulse signal according to the electrical signal and the optical signal after the contact). And interrupt the microprocessor It makes a state judgment. As shown in FIG. 6, the sensor module includes sensing contacts K1 to Kn, and the sensor can generate a signal according to the distance relationship between the contacts K1 and Kn and the light emitting end of the laser. After receiving the signal, the microprocessor analyzes and encrypts the signal, and then generates the signal. The corresponding n-digit password.
