The computer-controlled diagnostic machine 10 determines whether or not each item passes and displays an alarm and displays it on the screen, and processes the test data and statistics for each item to enable analysis by the operator, and prints the test result and error code items. The manual mode and the automatic mode can be used for the analysis processing work caused by any code generation, and self-implementation diagnoses the fault of each unit of the equipment.

In particular, the computer-controlled diagnostic device 10 receives the electronic control function of the vehicle according to the bar code attached to the vehicle, that is, received from the barcode scanner 30 according to the unique number and specification of the vehicle. Allows setting input to a control device, for example, an ECU automatically.

The DLC module 20 receives a lot of data measured by being connected to the diagnostic connector of the ECU of the vehicle, stores the data in a large capacity memory device, and transmits the data to the computer-controlled diagnostic device 10.

In addition, the barcode scanner 30 reads a barcode attached to the vehicle and transmits the unique number and specification of the vehicle to the computer controlled diagnostic apparatus 10 so that the electronic control function suitable for the vehicle is controlled by the computer controlled diagnostic apparatus 10. Make sure the settings are entered in. In general, a fixed bar code scanner is used for a process line of an automobile, but due to site specificity, the bar code scanner 30 uses a gun type scanner.

The printer 40 causes the computer-controlled diagnostic apparatus 10 analyzing the data obtained through the diagnostic connector of the vehicle to print the result on a sticker-treated sheet and prints an item and a code indicating whether there is a defect. Therefore, the printer 40 uses a label printer.

Next, the hardware configuration of these configurations is briefly described as follows.

The computer-controlled diagnostic device 10 is an industrial Pentium-class computer equipped with peripheral devices such as an input device and a display device.

The DLC module 20 includes a main control board and a power supply device.

The main control board is equipped with a 16-bit processor, a built-in 4MB memory card, direct communication with the ECU through the serial control and diagnostic connector with the computer control diagnostic 10, automatic boot in error The method is adopted, and the user's button according to the memory is supported.

The power supply device has a built-in noise filter, an overcurrent protection circuit, and a switching power having a low voltage and current variation rate.

In addition, the barcode scanner 30, a gun type scanner is used, which recognizes up to a maximum distance of 700mm, recognizes up to a radius of 500mm, and can scan 800 times per second. The gun-type scanner uses a laser diode light beam, is equipped with LCD and lamp identification, DB-9 serial ports, and other power supplies and other accessories.

In addition, the printer 40 uses a label printer, which is a tractor type without a 5 × 7 size dot matrix and a slip, and a sticker roll type is possible. In addition, it is equipped with a parallel data transmission and notification function when an error occurs.

On the other hand, reference numeral 50, which is not described in FIG. 1, is a computer system provided with a function for setting system data, a program update function, data collection and statistics, and transmitted to the computer controlled diagnostic apparatus 10. .

Reference numeral 60 is a computer that receives data from the computer controlled diagnostic apparatus 10 and collects test results and performs statistics.

Reference numeral 70 denotes a power stabilization device installed in the computer controlled diagnostic apparatus 10. That is, an uninterruptible power supply (UPS).
