1. Draw a table to record the kilometers traveled by vehicles. This table should include 100 grids, and each grid represents 100 km. On the left side of the table, write down an example of kilometers and write the word route at the top of the table.
2. Draw the scale of the odometer at the top of the table. The dial should include two hands, one representing the current mileage and the other representing the total mileage traveled. Write the words odometer on the dial and mark the position every 100 km.
3. Mark the position in the table. For example, when the vehicle travels100km, color the first column below the route; When the vehicle has traveled for 200 kilometers, color the second column below the route; And so on until the vehicle travels 1000 km, and color the tenth column below the route.
4. Record the mileage of each trip in the form. For example, when the vehicle travels100km, color the first grid on the dial below the current kilometer; When the vehicle has traveled 200 kilometers, color the second box below the current kilometer number on the dial; And so on until the vehicle travels 1000 km, and color the tenth square below the current km on the dial.
Application of odometer in automobile;
1. Monitor the driving distance: The most basic purpose of the odometer is to record the driving distance of the vehicle. This is very useful for car owners and managing the fleet. For example, the odometer can help the owner plan the next maintenance time, or estimate the distance from place A to place B.
2. Monitor fuel consumption: The odometer can record the fuel consumption of the vehicle and help the driver know how much fuel he has consumed during driving. This helps to manage fuel costs and protect the environment.
3. Diagnose the problem: If the car breaks down during driving, such as engine problems or flat tires, the odometer can help professionals to determine the time and place of the failure.
4. Route planning: Combined with GPS technology, the odometer can display the location of the vehicle on the map and the distance to the destination. This is very useful for route navigation and logistics transportation.
5. Safety monitoring: Some advanced odometers are also equipped with safety monitoring function. For example, when a vehicle collides, the odometer can automatically record the speed, G force and other data during the collision, which is very useful for accident analysis and insurance claims.
