If the central management office is able to know the sales status of the relevant offices nationwide from the PC in real time, it is related to the vehicle maintenance center management system equipped with a lift that can easily manage the maintenance results and the cumulative statistics for one month. .

Throughout the description of the present invention, first, the terminal is used as a concept including a personal computer (PC).

Although there is a prior art related to the communication means used in the present invention, there is no prior art that is directly related to the vehicle maintenance center management system equipped with the present invention, so the motivation for developing the present invention is as follows. Will be described.

At present, domestic auto repair shops are seeing more franchises in large and large companies than in small business owners. In addition, due to the nature of franchise franchisees, most of the investment costs are invested by the central management office, and franchisees take the form of taking some of the newly generated profits into income.

For this reason, it was necessary to centrally manage the usage of equipment in the affiliated stores in order to determine the current sales capability that is proportional to the income of franchisees that are opened nationwide.

In order to determine the current sales ability that is proportional to the income of the vehicle repair shop, the central management office needed to grasp the usage status of the equipment in the affiliate shop (maintenance shop, maintenance center, maintenance agency). Due to the dependence on the equipment use results according to the written statement or the sales results based on the verbal or written statement of the merchant, there was a problem in that the central office did not accurately manage the vehicle maintenance center.

The purpose of the present invention is to monitor (measure) the use information of the lift, the maintenance equipment on the PC, and to inform the server of the central management office through the Internet, the central management office in real time from the PC to the relevant office The purpose of this study is to provide a vehicle maintenance center management system equipped with a lift that can be used to know the operating status and to easily manage the maintenance results and cumulative statistics for one month.

Another object of the present invention is that there is a part that is consumed when using a certain number of times in the case of maintenance equipment, information about this is also collected in the central management system, to inform the vehicle maintenance center to request the equipment manufacturer To provide a possible vehicle maintenance center management system.

Hereinafter, a vehicle maintenance center management system equipped with a lift according to the present invention will be described in detail according to an embodiment shown in the accompanying drawings.

And a central management server 50 capable of transmitting and receiving data.

In addition, the first processing unit 11 of the controller 10 counts the number of times of use of the lift when the lift 1 stays longer than the reference height (H _reference ) or more than the reference time length (T _reference ). Storing data relating to the first storage unit 12; The data regarding the number of times of use of the lift stored in the first storage unit 12 is transferred to the terminal 40 by the communication between the first communication unit 20 and the second communication unit 30 and then the terminal 40 of the terminal 40. It is stored in the second storage unit 42.

The central management server 50 receives data about the number of times of use of the individual lifts belonging to the vehicle maintenance center from the terminals 40 of the plurality of vehicle maintenance centers at a predetermined time and transmits the data to the third storage unit 52. The management program 60 of the computer of the central management station acquires data on the number of times of use of the lift stored in the third storage unit 52 and displays statistics for each vehicle maintenance center or each lift. Periodic statistics may be daily statistics, monthly statistics.

In the present invention, the term "terminal" is used as a term that means connected to the server and communicates with the server, and is used as a concept including a personal computer (PC).

The management program 60 of the computer of the central management center sets the cumulative number of use of any one lift to one of the limit values (or N _{limit values} ) set for a specific part (or exceeds the limit value), or sets a period of use after purchase. In the event of coinciding with (or exceeding) the limit period (T _{limit period} ), it may be further equipped with a function for displaying a replacement message for that particular part.

The lift 1 includes a weight sensor 6 capable of sensing the weight of the vehicle on which the lift 1 is mounted, and the lift current payload (W _current ) detected by the weight sensor 6 is greater than or equal to the reference weight (W _reference ). (In case of equality or exceeding), the first processing unit 11 of the controller 10 may be used only once when the lift 1 stays longer than the reference height (H _reference ) or more than the reference time (T _reference ). Can be configured to count.

The first processor 11 multiplies the time T _up operating in the ON state of the up button 13 provided in the controller 10 by the estimated ascending speed V _up of the preset lift (1). It is possible to determine whether the lift 1 is greater than or equal to the reference height (H _reference ) by calculating the present height (H _present ) of the _current position and comparing it with the reference height (H _reference ) of the lift 1.

When the position of the lift can be continuously calculated by a sensor capable of continuously detecting the position of the lift (for example, when using an encoder or a potentiometer), the first processing unit 11 receives the lift (1). ) whether or not the reference height (H _standard) above is subjected to a step of determining in advance the comparison set (input) by the height (H _standard) and the current height of the lift (1) (H _current).
