Description

Vehicle consumable parts inspection and replacement cycle display device considering engine usage conditions {Vehicle Indicator for the Exchange of the Exhausting Parts considering the Driving Condition}

As shown in FIG. 1, the rotation 1 of the automobile engine is performed while the gas compressed in the combustion chamber is exploded by the ignition flame generated by the engine igniter 2. The engine igniter is supplied with a high voltage for generating an ignition flame in the form of an ignition pulse (3). The signal is branched to count the number of pulses in the counter (4), and the revolutions per minute (rpm, revolution per) In terms of minute), the tachometer 5 displays the revolutions per minute (6).

As shown in FIG. 2, the ignition pulse output is converted into an analog voltage by a frequency to voltage circuit (1), and the engine speed in the form of the converted analog voltage is an analog to digital converter (analog to digital). converter) to digital values. The digital voltage proportional to the converted engine speed is based on the engine speed measured by the CPU (4) in which the program is built, the rate of change of the engine speed for a predetermined time, and the start-up based on the sampling interval. Calculate the running time from the turn on until the start is turned off and the cumulative engine speed signal integration.

Calculating the total cumulative pulse applied to the consumable parts replacement judgment based on the engine oil replacement cycle, 10000 Km, which has been presented up to now, it is possible to maintain a constant 167 hours at a speed of about 3000 rpm based on the average speed of 60 Km / h. If you drive at speed, you drive 10,000 Km. Therefore, assuming that the crankshaft rotates one revolution by one explosion by interlocking spark plugs for a four-stroke engine, the total cumulative pulses generated when driving 1000 Km are as follows.

3000 revolution / minute × 1pulse / revolution × 60 minutes × 167 hours = 30 × 10 ⁶ pulses In addition, the method of considering the operating conditions (operation frequency and operating time) based on the engine speed is the same as in the following table. When the total number of driving cycles is reached and the total driving time is short, when the low-speed driving is frequent, it can be indirectly recognized as a city driving condition, and the driving time is small but the driving time is long. When the engine idles a lot without affecting the running, it means a driving condition with a lot of idling like in winter.

In addition, when both the number of driving and the driving time are small, the long distance is driven at a high speed, indicating indirectly that there are many highway driving. Therefore, by using the measured engine speed, operating frequency and time, it is possible to indirectly determine the driving state, and in each case, the weight that affects the replacement cycle of the consumable parts is set to reach the same total engine speed. In this case, it is possible to display the replacement period of the consumable parts by considering the weight, considering the operating conditions.

FIG. 3 is a circuit diagram of a frequency-to-voltage circuit described in FIG. 2, wherein a voltage capable of driving a circuit by a driving voltage supply unit 1 is applied, and a pulse input input from an engine igniter. (2) is converted into an analog voltage output (3).

FIG. 4 is a diagram showing the correlation between the arithmetic unit, the memory unit, and the display unit. Consumable parts of the arithmetic unit 3 are the result (1) of converting the input rotational analog signal into a digital value by an analog-digital converter. The calculation for determining the replacement cycle is performed, and the result is stored in the storage device 4. Power supplied to the computing device and the memory device is supplied by the power supply device 4, which is connected to the battery of the vehicle. The operation time from the start to the end of the operation is calculated by the timer set in the computing device, the total engine speed until the start is turned off, and stored in the storage device. After the end of operation, at the start of the next operation, the engine speed is newly counted based on the last engine speed from the moment when the power is supplied, and stored in the storage device by the same method, and the result is displayed on the display device 5. .

5 is a view showing the principle that the input value is set and displayed to display the replacement cycle of the consumable parts, the engine speed set value (6) and the speed band (5) is entered, the calculated engine speed total When (7) reaches a negative and positive band width around the set value, the color of the display device is changed from the color (1) representing 'normal' to the color (2) representing 'caution'. At this time, the color indicating normal for a predetermined time may be repeated while the color is switched. In addition, even though the color of the display device indicates caution, when the consumables are not replaced because the consumable parts are not replaced even at a constant time or engine speed even in the converted state, the color of the LED indicates a caution. It will be converted to a color (3) representing the 'alarm'. In this case, the color indicating attention is turned on for a predetermined time, and then the color of the LED may be converted and displayed.

6 is a diagram illustrating a method for checking consumable parts and calculating a replacement cycle according to the engine speed, which is started in the stationary state 1 and changes the engine speed during driving. At this time, the change rate (3) of the engine speed to be changed is calculated, and it is checked whether the upper limit and the lower limit of the engine speed are exceeded, and the speed change rate and the set value are reached. Display the result to the driver. Further, the total operating time is calculated by calculating the required time 7 from the engine driving state 5 in the stationary state in which the engine speed is constant to the stopped state 6 in which the engine rotation is completely stopped.

7 is a diagram showing the integrated management using the central server, the explosion signal (2) of the spark plug generated from the engine 1 to secure the data related to the automotive consumables through the apparatus 3 of the present invention, wired and wireless It transfers to the central server 6 using the Internet communication method (5). The server integrates and manages the data transmitted from each vehicle and transmits the result to the client 7 via the Internet. In addition, by using information transmission methods such as a wireless communication device, PCS, and e-mail, consumable parts related information is provided to the driver of each vehicle (8).

In the display device 3, the consumable parts are displayed on the circular perimeter. The display panel is supported by the spring and can be restored after the panel is pressed. In addition, the replacement cycle of the consumable parts in which the LED is embedded is indicated by lighting of the LED, and when the consumable parts are checked and the replacement is made, pressing the display panel resets the consumable parts replacement cycle value. In the center of the circular panel, a time display device 4 using a timer may be added.

Also, after checking or replacing the consumables, the reset method is performed by pressing the reset key 3. Since the device is mounted in an engine room, which is a harsh environment, the cover 7 is provided so as not to be affected by impurities such as dust and oil. In particular, the sealing rubber 8 is applied to the cover to prevent impurities from penetrating into the liquid crystal monitor. .
