Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile inspection and diagnosis device that automatically displays inspection and diagnosis instructions according to a selectively specified automobile inspection type.

There are an extremely large number of inspection items in automobile inspection, diagnosis, and maintenance work, and in particular, the statutory 6-month and statutory 12-month inspections exceed IOC costs.

Memorizing all of these items and performing the work in an orderly manner is of course an extremely difficult skill, and the most commonly used method is to prepare a periodic inspection and maintenance record book, read the inspection items, understand the work contents, and carry out the work. This can be done by following a sequence or by using a large hawk-light type dial, such as those often seen at vehicle inspection stations. However, in both cases, there is a possibility of misreading or writing errors due to the large number of inspection items listed, and in the latter case, it is difficult to display all items on the dial, in other words, the display area The disadvantage was that the amount of data was enormous. The present invention eliminates the drawbacks of the conventional methods described above and displays items to be inspected and work instructions in a sequential order so that they can be understood at a glance, thereby allowing inspection work to be carried out quickly, reliably, and efficiently. In particular, there are no misreadings or typos as mentioned above, and in addition, the area equivalent to the display panel can be made of a reasonable size that is easy to see, and it can be easily moved to a convenient position for use. The purpose of the present invention is to provide an automobile inspection and diagnosis device that makes it possible to perform vehicle inspection and diagnosis.

For example, as illustrated in FIGS. 2, 3, and 4, the configuration is such that an inspection type indicator light 12,
13 and 14 are discussed, and the characters of the inspection type are displayed by lighting. A reversing blade 22 of a reversing display 15, which will be described later, can be seen through the window at the center of the front panel, and two inspection instructions are displayed there. On the left side of the window, there are inspection indicator lights 16 and 17 corresponding to the display position of each inspection procedure, indicating whether or not the item indicated on the reverse display 15 corresponds to the type of inspection to be carried out. There are inspection result indicator lights GOOD18 and BADI that indicate the quality of the inspection results corresponding to the display position of each inspection item.
9 are respectively 18a, i8b and 19a, 1 in the upper and lower two rows.
9b, and the BAD indicator light 19 is preferably colored red. A reversing display 15 with a pulse motor 23 is installed inside the outer weight 11, and a large number of reversing blades 22a, 2 are supported by disks 21a, 21b fixed to its rotating shaft.
2b...22n are attached in the shape of waterwheel blades, and the above-mentioned inspection items with order of implementation are written on the front and back of the reversing blades.

The functions of the display device 7 are as follows.

That is, upon receiving an inspection type selection signal from the inspection type selection device 5, the corresponding inspection type indicator light (for example, 12) is lit. Upon receiving a matching signal between the inspection type and the inspection item from the inspection item selection circuit 6, the corresponding inspection indicator light (16, 17
or either one). Upon receiving the inspection result signal from the operation panel 8, the corresponding inspection instruction lamp is turned off, and the corresponding inspection result display lamp 18 (or 19) is turned on, and after a few seconds, it is turned off. Upon receiving the inspection result reset signal from the operation panel 8 and the measuring equipment signal transmitter 2, the corresponding inspection instruction light is turned on. Operation panel 8: As shown in FIG. 5, it is a push-button type command transmitting device layer, and all signals are sent to the central control device 1 or to predetermined component devices via the central control device.

In the upper half of the front panel of the case 29, there are inspection result push buttons GOOD (indicated by 24), BAD (indicated by 25), and inspection result push buttons corresponding to the number of inspection item display frames (in this embodiment, 2 frames). Reset pushbutton RES (indicated by numeral 26)
are arranged in two columns 24a, 24b and 25a, 25b, respectively.
and 26a, 26b, and below them, on the left side, there are two vertical rows of push buttons 27a, 27 corresponding to the number of inspection item display frames.

28 are provided. The pushbuttons GOOD and BAD turn off the corresponding inspection indicator lights 16 and 17 on the display device 7,
In addition, the inspection result indicator lights 18 and 19 are temporarily turned on to display the inspection results of the instructed inspection items on the inspection indicator lights 16 and 17, and the printer 9 is sent to the central controller 1.
This is to activate the record of. The pushbutton RES is used to correct the action of the inspection result pushbutton, and it lights up the corresponding inspection indicator light 16 and turtle 7 again, and
The central control unit 1 is made to engrave a correction (REV) symbol on the printer's correction inspection result record to be performed next time. The pushbutton PASS is used to turn off the corresponding inspection indicator lights 16 and 17 when there is no corresponding inspection item among the displayed inspection items because the vehicle type is different, and the pushbutton STEP The inverter 15 of the display device is rotated one step at a time to display the next inspection item. Printer 9: Inspection items, their results, and corrections (
REV) mark, etc.

The configuration is based on a well-known technology, and its explanation will be omitted. Next, the effects of the above configuration will be described.

To operate this vehicle inspection and diagnosis device, after connecting the power source, first press the button corresponding to the type of inspection to be performed on the inspection type selection device 5.

As a result, the designated inspection type indicator lamp, for example, the lamp 12 on the display device 7 is lit. The inspection item selection circuit 6 indicates whether the inspection items currently displayed on the display device 7 are to be carried out in this inspection and are in the correct order of execution.
The information from the inspection procedure storage circuit 4 is compared and determined, and the corresponding indicator lights 16 and 17 are turned on only when they match. The inspection worker inspects the vehicle to be inspected regarding the inspection items (inspection items, work contents, etc.) displayed on the right side corresponding to the illuminated inspection instruction lights 16 and 17. If the vehicle does not have the equipment or equipment for the applicable inspection item because it belongs to the same inspection type but is a different vehicle model,
Press the push button PASS on the operation panel 8 to turn off the corresponding inspection indicator light. In addition, if the displayed inspection items do not match the information from the inspection procedure memory circuit 4 and all inspection indicator lights are off, press the pushbutton STEP to change the display of inspection items, and then Repeat the push button STEP until the inspection indicator light lights up to display the appropriate inspection items that match. For example, when the statutory six-month inspection is selected in the inspection type selection device 5, the inspection type indicator light 12 is turned on by an easily conceivable electric circuit (not shown).

Inspection items (or work details) are written on the front and back of the reversing blades 22a, 22b...22n of the reversing display 15.
As shown in the figure, the display 15 displays two items at once to the inspector.

Each inspection item (or work content) is stored in the inspection procedure memory circuit 4.
The items displayed on the reverse display 15 are compared with the inspection item selection circuit 6, and if applicable, the inspection indicator lights 16 and 17 are turned on. Turn on the light to instruct the inspector that the designated inspection item (or work content) is required for the type of inspection.

The person inspecting the vehicle with the operation panel 8 shown in FIG. 5 can check whether the inspection indicator light 16 or 17 is on and whether the corresponding reversing blade entry is correct or not by visual inspection as shown in FIG. If it is an inspection item that can be determined, the relevant part of the car is inspected and diagnosed, and if the result is good, for example, if the radiator cap is in good condition as shown in Figure 2, the radiator cap is in good condition.
Press button 24a.

Then, by an easily conceivable electrical circuit (not shown), G
OOD lamp 1 8a lights up for a certain period of time, and inspection indicator lamp 1
6 goes out. On the other hand, when it is determined that the inspection and diagnosis result is bad, press the BAD button 25a and the BAD lamp 198 will be lit for a certain period of time using the same circuit (not shown) as in the case of D in q, and the inspection indicator light 16 will be turned on. Lights out. In addition, if the vehicle to be inspected does not have a transfer inspection item, pressing either the PASS button 27a or 27b turns off the corresponding inspection indicator light 16 or stove 7. The results of operating such a control panel are printed on the recording paper 1 by the printer 9.
01 is printed out, but the explanation is omitted because the electrical circuit is easy to think of.The entries for the reversing blade are mainly inspected using measuring equipment as shown in Figure 6 N and V. If the work is carried out according to the L instructions, the signal from the measuring instrument signal transmitter 2 will pass through the measuring signal converter circuit 3 and the central controller 1 and be recorded as measured values on the recording paper 10 by the printer 9. A message will be printed out saying ``Inspection indicator light 16 or 17 will go out.''

Repeat the above steps, and when both the inspection indicator light 16 and the light 7 go out, press the STEP button 28, and rotate the pulse motor 23 one step in the direction A shown in the figure using an easily thoughtable electric circuit (not shown), and the reversing blade 22a ,22b,...
- 22n inverts one sheet in the direction C in the figure and instructs the automobile inspector about the next inspection item or work content. By repeating the above steps, the inspection and diagnosis of the vehicle to be inspected can be completed. If the pushbuttons D and BAD are pressed incorrectly, a correction record can be created by pushing the pushbutton RES and then correctly pushing the corresponding inspection results pushbutton again. It goes without saying that various changes other than those described above may be made without departing from the spirit of the present invention. For example, in this embodiment, inspection items or work details are printed one each on the front and back of the reversing blade 22, but it is possible to print a large number of inspection items or work details. You can print out the item and add inspection indicator lights accordingly, or the pulse motor 23 will automatically rotate when all inspection indicator lights go out.
The next inspection item or work details are displayed. As explained above, the present invention provides an inspection type selection device that selects only a required inspection type from among the set inspection types of automobiles, and an inspection type selection device that selects only a required inspection type from among the set inspection types of automobiles, and the inspection items and inspection types included in the inspection types set in the inspection type selection device. An inspection procedure memory circuit that stores the order of implementation of inspection items for each inspection type and a signal of the inspection type selected by the inspection type selection device are input, and the signal of the skin inspection type and the inspection procedure memory circuit are input. An inspection item selection circuit selects an inspection item corresponding to the selected inspection type from the inspection procedure storage circuit by comparing the inspection items with the stored inspection items, and the inspection item selection circuit selects the inspection item corresponding to the selected inspection type from the inspection procedure storage circuit; A display device that displays inspection items and inspection and diagnosis results, and a central control device that has a computer connected to an operation panel and operates the inspection item selection circuit and display device, and is operated from the central control device. Since the system is configured to automatically select inspection items corresponding to the inspection type based on the signal and display them on the display device, if the operator selects only the inspection type and inputs it into the central control unit using the inspection type selection device, The inspection item selection circuit automatically selects the inspection items corresponding to the type of inspection and displays them on the display device in accordance with the order in which they are to be carried out, so inspections can be performed reliably and quickly with extremely simple operations. The storage capacity of the instruction storage circuit can also be kept to a minimum. In addition, the entire device can be compactly assembled and is easy to transport.
