[0139] Taking into further consideration that the customer can be notified in time when the repair of the electronic device 105 is completed, the management system of the intelligent data management device 409 also includes a customer automatic notification management module 508. When the database management center 503 obtains that the repair of an electronic product is about to be completed, the customer automatic notification management module 508 will inform the customer in the form of a text message to arrive at the site in time to pick up the electronic product that has just been repaired.

[0140] The specific timing of the automatic customer notification management module 508 notifying the customer depends on the current distance of the customer from the electronic product repair site and the estimated time to complete the repair according to the current repair progress.

[0141] The customer's current distance from the electronic product repair location can be obtained by querying the customer's location through the mobile phone tracker on the customer's registered mobile phone, and combined with the situation of the preset electronic product repair location, the route planner plans the shortest distance between the two as the dividend, and obtains the customer's average travel speed as the divisor, thereby obtaining the time it takes for the customer to arrive at the site. The average travel speed of the customer mentioned here is the quotient of the total distance traveled by the customer and the total time spent by the customer for the corresponding total distance.

[0142] The estimated time to complete maintenance according to the current maintenance progress is based on the average time taken by the maintenance personnel to complete maintenance in the past and the current period to comprehensively analyze the specific time period for completing maintenance.

[0143] The implementation principle of the management system of the intelligent data management device 409 is: after logging into the system and inputting the corresponding maintenance plan and required parts, the maintenance quotation management module 506 can promptly generate a quotation and notify the user through display, and at the same time, based on the current inventory situation of maintenance parts, promptly place an order to purchase the missing parts. At the same time, when the electronic device 105 is repaired, the customer will be informed in time, so that the customer can obtain the repaired electronic device 105 in time.

[0144] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
