As shown in the table structure explanatory diagram of FIG. 10, the assessment criterion database is configured to include four fields of a product code, a superiority, an increase / decrease amount (rate), and a unit.
[0094]
The product code indicates a product code of a product to be certified, and is stored in an integer type. The product code matches the product code in the product table (FIG. 6) such as, for example, wax car wash “7540 *”.
[0095]
The superiority is stored as a numerical value to indicate whether or not it is superior, and if the condition is superior, "1" is stored. In the case where the superiority is set in a plurality of stages by the superior certification items output from the host computer 10, it is assumed that the superiority of this assessment criterion table is also set in a plurality of stages so as to allow more detailed assessment. good.
[0096]
The increase / decrease amount (rate) indicates an amount or a ratio for increasing / decreasing the assessment amount, and is stored in a numerical form.
The unit indicates a unit of the increase / decrease amount (rate), and stores% or a circle in a text type.
[0097]
In addition, the above-mentioned assessment program executes a process of increasing or decreasing the purchase price or the sale price based on the excellent certification items with respect to the general assessment price based on the vehicle type, year, mileage, injury, accident history and the like. .
[0098]
Specifically, for example, if the cigarette is not smoked in the car, the increase is 10,000 yen, and if the car is washed frequently, the total amount is increased by 1%. The increase amount for the excellent certification items that have been added is added. Further, if there is no excellent certification item to be displayed if the maintenance is performed normally, it is desirable to do nothing, but it is also possible to set so as to reduce the assessment amount.
[0099]
With the above configuration, the clerk of a used car dealer can input the contents of the car maintenance certificate 61 with the keyboard 75 and display the assessed value on the monitor 74. In addition, the assessed amount can be printed by a printer 78 and output on paper such as paper or a transparent sheet.
[0100]
Next, a process for inputting data related to maintenance will be described with reference to a process flowchart showing the operation of the control device 43 of the POS terminal 40 shown in FIG.
First, as an SS clerk's job, when the automobile 7 enters the SS store as shown in FIG. 1, the SS clerk receives the membership card 5 from the SS member who is a driver, and receives the membership card 5 for refueling, oil purchase, and safety check. Listen to the service you want.
[0101]
When the member card 5 is passed through the card reader 45 by the SS clerk, the card reader 45 reads data recorded on the member card 5, and the control device 43, which has received the data as a communication signal, temporarily stores the data in the RAM (step). p1).
[0102]
When the SS clerk inputs maintenance data and other necessary data such as a maintenance number such as a product number, a service number, and an additional service number on the input panel 46, the controller 43 temporarily stores the data in the RAM in association with the card number. (Step p2).
[0103]
The control device 43 confirms whether or not there is a refueling instruction in the input data (step p3), and when there is a refueling instruction (presses the execution button), the specified fixed weighing machine 2 outputs the specified amount. Refueling is started (step p4).
[0104]
If the SS clerk replaces the ashtray or cleans the window during refueling (or after entering the maintenance number, etc.), and there is additional data such as the mileage and the presence or absence of butts on the ashtray (step p6), the SS clerk Allows input of additional data on the input panel 46 (step p6).
[0105]
The control device 43 sends the input data and the data on the RAM together to the host computer 10 (step p7), and ends the process.
[0106]
Through the above operation, the maintenance data can be transmitted to the host computer 10 each time the SS member visits the SS store. The host computer 10 stores the received data in the history table of the management database. As a result, SS members frequently perform oil replenishment and the like, and perform necessary maintenance (inspection) as needed in order to raise the price when selling the used car later.
[0107]
Next, the vehicle maintenance certificate 61 is issued with reference to the processing flow diagram showing the operation of the control device 13 of the host computer 10 shown in FIG. 12 and the screen image explanatory diagram of the vehicle maintenance certificate issuance screen shown in FIG. Will be described.
[0108]
As shown in FIG. 13A, the control device 13 displays a card number input screen for receiving a card number input on the monitor 14 as an initial screen. The card number input screen is provided with a list box type input box 14a for inputting a card number, so that a plurality of card numbers can be input at once by separating with a comma.
[0109]
When the card number is inputted by the attendant using the keyboard 15 (step n1), the processing screen shown in (B) is displayed on the monitor 14. Here, the control device 13 activates the certificate issuing program, and extracts all records (data) whose card numbers match and whose sales date and time are after the issue date of the member card 5 from the history table according to the certificate issuing program. (Step n2).
[0110]
When the data extraction from the history table is completed, the data with a category of 0 is deleted from the extracted data, and the data is totaled by category (monthly, butts, etc.) for each product, and the totaled data is arranged in order of date by product. Product-specific list data is created (step n3).
[0111]
The control device 13 compares the total value or the average value of the product-specific list data for each product with the excellent conditions in the product table, and extracts products satisfying the excellent conditions as excellent data (step n4). At this time, a sentence according to the category is added to the product name of the extracted excellent data with reference to the excellent certification text table to create an excellent certification text.
[0112]
When the creation of the excellent certification text is completed, the control device 13 displays a print execution screen shown in FIG. 4C on the monitor 14, and when the print button 14c is clicked with the mouse 16 by the attendant, sends a print signal to the printer 18. Then, the cover of the automobile maintenance certificate 61 is printed using the first cassette of the painter 18 (step n5).
[0113]
Here, the cover of the car maintenance certificate 61 will be described. As shown in the plan view of FIG. 14, the certification text 63 is printed on a mount 62 on which a special printing such as gold or a color printing such as blue has been performed in advance. I do.
The certification text 63 includes a vehicle type, a number, a certification period (from the date of issuance of a membership card to the date of issuance of the car maintenance certificate 61), an owner (SS member name), and excellent certification items.
[0114]
The excellent certification item is the excellent certification text created from the excellent data in step n4 described above. For example, if the product name “wax car wash” is performed more frequently than the excellent condition, “wax car wash” (FIG. 6) A sentence is created by adding a character string of “: frequently performed” (a text with a classification of 1 in the excellent certification text table of FIG. 8) to a character string of “set to 1 in the product table”. I have.
[0115]
When the printing of the cover is completed in this way, the control device 13 transmits a print signal to the printer 18 and uses the second-stage cassette of the painter 18 to generate the vehicle maintenance certificate 61 shown in FIGS. A list display of the text (second and subsequent pages) is printed (step n6). FIG. 15 shows a first part of the list display (other than car washing), and FIG. 16 shows a second part of the list display (car washing related).
[0116]
Here, the list display of the car maintenance certificate 61 will be described. In this example, one page other than the car wash related page shown in FIG. 15 (first page of the list) and three pages (2 (4th page to 4th page).
[0117]
Pages other than those related to car washing (FIG. 15) are displayed in a list of four items: maintenance items (maintenance items), classification, contents, and mileage.
[0118]
The car wash related page (FIG. 16) displays items related to car wash such as shampoo car wash, wax car wash, W wax wash, and the like, and displays the number of times for each monthly index (time) in the vertical direction. For example, assuming that a wax car wash was performed once in January 1996 and no other car wash was performed, 1 is displayed in a cell where the wax car wash intersects with January 1996, and the January 1996 wash was performed. Leave other cells blank.
[0119]
It should be noted that both the non-car wash related pages and the car wash related pages display a car name (model), year, color, new or used car purchase, customer name (SS member name), and the number of pages as a header at the top. In the lower part, the certificate No. on the left side as a footer. And the certification date and certification authority are displayed on the right.
[0120]
The proof of the car maintenance certificate 61 is the certificate No. displayed on the cover. And the certificate No. of the list display. By specifying the number of pages in the list on the cover, complete consistency of the certification contents of the entire vehicle maintenance certificate 61 is measured.
[0121]
After printing the car maintenance certificate 61 in this manner, the control device prints the address of the SS member on the envelope stored in the third cassette of the printer 18 (step n7), ends the certificate issuing program, and performs processing. To end. In addition, by this printing process, the staff can mail the car maintenance certificate 61 to the SS member only by enclosing the car maintenance certificate 61 in an envelope, affixing a stamp, and mailing it to a post, thereby improving work efficiency. ing.
[0122]
By the above operation, the staff member simply inputs the card number and clicks the print button, the excellent certification items are extracted and displayed on the cover, and the maintenance contents (maintenance contents) are displayed in detail in the list display (text). The certificate 61 can be printed and mailed.
[0123]
The SS member receiving the car maintenance certificate 61 can negotiate to increase the purchase price by presenting the car maintenance certificate 61 when having the used car dealer buy the car.
[0124]
In addition, a used car dealer who bought a car can objectively and accurately know how to handle the car by using the car maintenance certificate 61, which can be used as a material for assessing the amount of money, and can be used as a material for evaluating customers. You can objectively appeal what was treated with great care, add value and sell at a high price.
[0125]
When the data output button 14b is clicked in FIG. 13C, data is output to a recording medium such as a CD-R. This data includes all certification data to be printed on the car maintenance certificate 61. As a result, it is also possible to use a personal computer or the like to read the storage medium at a used shop and automatically calculate the assessment amount from the contents of the certification data using an assessment program.
[0126]
However, in this case, it is desirable to encrypt the certification data recorded on the recording medium in consideration of the risk of unauthorized rewriting of data. For this encryption, for example, a method of using a public key of a used car shop and using a secret key at the used car shop to perform decryption can be used. This encrypted data may be created as a plurality of encrypted data in order to correspond to a plurality of used car dealers, or may be operated so that it can be decrypted with the same key at a plurality of used car dealers. good. Further, an IC card, a magnetic card, or the like may be used as the storage medium.
[0127]
Next, the process of calculating the assessment amount will be described with reference to a process flowchart showing the operation of the control device 73 of the assessment terminal 70 shown in FIG.
First, a clerk of a used car dealer performs a general assessment, and inputs the general assessment amount using the keyboard 75 (step s1).
[0128]
If there is certification data recorded on the CD-R (step s2), the certification data is read by the CD-ROM drive 77 (step s3). Manually inputs excellent items (certification data) using the keyboard 75 (step s4). If the certification data recorded on the CD-R is encrypted when the certification data is read, decryption is performed simultaneously with the reading.
[0129]
When the input or reading is completed, the control device 73 refers to the assessment reference database (step s6), activates the assessment amount calculation program, and calculates the assessment amount (step s6).
[0130]
The calculated evaluation value is displayed on the monitor 74 (step s7), and the clerk selects whether or not to print (step s8).
When the printing is selected, the evaluation value is printed by the printer 18 together with the vehicle type (vehicle name) and the number (step s9), and the process is terminated.
[0131]
With the above operation, accurate and quick assessment can be performed easily. In addition, since the assessment amount is calculated according to the assessment standard table, the assessment can always be performed based on a fixed standard. In addition, if the contents of the assessment reference table are disclosed, highly transparent assessment can be realized, and dissatisfaction of those who are assessed can be eliminated and satisfaction can be improved.
[0132]
As described above, the objective car maintenance certificate 61 (car chart) was used to measure the transparency of the assessment, which was opaque, and to bring the customers who have avoided using a used car to the used car market due to the opacity. Thus, the used car trading market can be activated. Furthermore, the motivation to carry out necessary maintenance (maintenance) properly can be given to the SS members who are drivers, and the demand for services such as maintenance supplies purchase and safety inspections at SSs is expanded to stimulate the SS industry. You can also plan.
[0133]
In addition, the driver's consciousness about the maintenance of the vehicle can be improved, and the vehicle can be prevented from running in a dangerous state such as an accident due to poor maintenance or a broken lamp, thereby contributing to the improvement of safety in the automotive society.
[0134]
In this embodiment, a member card 5 specialized for the certification system 1 is used, but an existing member card used in the SS may be used. In this case, a card table may be added to the management database of the host computer 10 and items not recorded on the membership card may be stored using the card number as a key.
[0135]
Further, an item of the maintenance start date may be added to the data recorded on the member card 5 so as to be able to cope with replacement of the car. In this case, for example, when the vehicle maintenance certificate 61 is issued, the maintenance start date is updated when the vehicle maintenance certificate 61 is issued.
[0136]
In other words, if the car maintenance certificate 61 is issued for replacement of a car, the next SS use will be a new car, so updating the maintenance start date first will ensure that the car to be certified can be switched. it can.
[0137]
In addition, when the maintenance start date is updated, if the vehicle type and number are cleared (deleted), an error is displayed at the SS store at the next use, and the SS clerk surely displays the new vehicle type and number at the POS terminal 40. Can be entered. The present invention is not limited to this, and the update of the maintenance start date and the update of the vehicle type and the number may be self-reported by the SS user.
[0138]
Further, when creating excellent certification items, it may be determined whether or not products of similar types are collectively fulfilled the conditions. For example, if the wax wash and the W wax wash are combined into a wax wash, even if the wax wash alone does not satisfy the excellent conditions, at least the wax wash is excellent by reflecting the higher number of times the W wax wash is performed. You can prove that it was done.
[0139]
In addition, if the contents of the maintenance are automatically checked periodically and the SS member who was excellent is likely to become inferior, or if there is an item that it will be excellent if you come to the store for maintenance this month, DM (Direct mail) or the like may be used to display the current results (results related to maintenance) and guide the members to the store. As a result, members can be encouraged to come to the store, and sales can be increased by promoting sales promotion of products.
[0140]
In addition, an advertisement recommending a used car dealer who signed a contract with a parent company of the SS and a parent company of the SS that highly value the car maintenance certificate 61, and encouraging the issue of the car maintenance certificate 61 is enclosed. May be. As a result, the SS member can select an appropriate used car dealer and can also control to increase the value of the car maintenance certificate 61.
[0141]
In addition, the management database stores a store table including fields such as an SS store code, an SS store name, and an SS store address, and the history table also stores an SS store code. The SS store may be known. Thereby, the SS store using the certification system 1 can be confirmed.
[0142]
Further, the host computer 10 may be connected to the Internet 9 as shown by a virtual line in FIG. In this case, if certification data such as good certification items are stored in the management database as the data output of FIG. 13C for each card number, the assessment terminal 70 can access the certification data in the management database. Can be. As a result, if the card number of the member card 5 is input at the assessment terminal 70, it is possible to calculate the assessment amount reflecting the authentication data.
[0143]
Further, the certification system 1 may be used at a car dealer or a car accessory store instead of the SS. In this case, a computer such as a PC (personal computer) may be provided as the POS terminal 40. The computer can be configured with the same control circuit as the management server 10 described with reference to FIG. 5, and data stored in the hard disk may be used as a data input program.
[0144]
For example, when the system configuration of the certification system 1 used in a car dealer is illustrated, the system configuration is as shown in FIG. In this example, a notebook PC is used as a computer used as the POS terminal 40. The card number of the member card 5 may be input by a clerk of a car dealer using a keyboard, or a card reader may be serially connected to a notebook PC to perform magnetic reading.
[0145]
The host computer 10 may be installed in a car dealer (or in an accessory store) together with a notebook PC, or may be installed in a headquarters uniting a plurality of car dealers (or a headquarter uniting a plurality of accessory stores).
[0146]
With the above configuration, it is possible to provide the certification system 1 that is compatible with a car dealer (or an automobile accessory store). In particular, car dealers will be able to collect a wide range of information from new car information to used car information and maintenance information.For example, "Customers who have purchased a car at our shop and received proper maintenance at our shop will have a car maintenance certificate. The purchase will be made at a high price in consideration of the proof matter of the book 61. "
[0147]
Further, two or more of the SS, the car dealer, and the car accessory store may be affiliated with each other, and any of the affiliated stores may be configured to be able to perform input by the POS terminal 40 (or computer).
[0148]
In this case, a POS terminal 40 of an SS store, a POS terminal 40 (computer) of a car dealer, or a terminal of an affiliated POS terminal of an automobile accessory store is connected to a host computer via a line such as the Internet 9. 10 and may be configured to transmit only data related to maintenance.
[0149]
In the case of the cooperative system as described above, the host computer 10 may be installed in any one of the SS headquarters, the car dealership headquarters, the car accessory dealer headquarters, or the car maintenance certification company headquarters. May be installed. Here, the vehicle maintenance certification company headquarters refers to a company (company) in which a management company (management company) that manages the certification system 1 is independently established.
[0150]
Further, in this case, a table in which the card number of the member card of the automobile accessory store and the card number of the member card 5 of the SS store are preferably stored in the management database. Alternatively, a configuration may be adopted in which the customer is presented with the membership card 5 of the SS store at an automobile accessory store, and the card number of the membership card is transmitted to the host computer 10 manually or automatically by a card reader.
[0151]
As a result, not only SS stores but also oils and the like purchased at automobile accessory stores are proved as maintenance facts, so that the number of options of the store for purchasing the maintenance products of the user (SS member) is increased, and the convenience is improved.
[0152]
Further, the host computer 10 and the POS terminal 40 may be integrated so as to be executable stand-alone as an automobile maintenance record certification device. In this case, only one store can provide the car maintenance record certification service.
[0153]
The excellent certification items to be extracted on the cover may be set so that any item can be selected. Thus, for example, if the automobile maintenance certificate 61 is reissued in response to a request from a used car dealer, it is possible to narrow down the items to be appealed at the used car dealer and conduct business.
[0154]
That is, for example, for the car A, a feeling of cleanliness, such as the fact that the car was wax-washed, is printed on the cover, and the oil change is an excellent matter, but is not displayed on the cover. It is possible to say on the cover that the vehicle was well-maintained, such as safety inspections, etc., and not to indicate on the cover that polymer washing was performed well.
[0155]
In this way, the business is launched with features on the cover, and there is also a good point in other parts in the list display (Car A has good oil change, Car B has good polymer wash, etc.) You can develop a sufficient sales strategy for customers who are considering purchasing.
[0156]
Further, a computer such as a personal computer capable of communicating with the host computer 10 may be installed in the SS store, a certificate issuing program may be installed in the computer, and the vehicle maintenance certificate 61 may be issued in the SS store. . In this case, the member (user) can easily and quickly receive the issuance of the car maintenance certificate 61 at the SS store where the member (user) is always using, so that the convenience is improved and the mailing cost can be reduced. In this case, the name of the SS store issued in the car maintenance certificate 61 may be described, or the total number of uses and the number of times the SS store is used may be described.
[0157]
Further, other items such as “presence / absence of pet” may be added to the product table so that more detailed information can be provided. For example, if there is a pet, the presence or absence of pet hair may be checked at the time of in-house cleaning in a car wash or the like, and the presence or absence of the pet may be input from the POS terminal 40. As a result, it is possible to prove the presence or absence of a pet that causes the inside of the company to be dirty, and it is possible to provide important information for a purchaser of a used car who dislikes a pet.
In this manner, as the number of items in the product table increases, appropriate information can be objectively proved and provided for various types of information requested by a used car buyer.
