An AC signal or a pulse signal having a frequency compared with the vehicle speed from 5 is taken into the distance signal generating unit 16, and the distance signal generating unit 16 performs waveform shaping and the like to obtain a signal capable of distance calculation. Is supplied to. The microprocessor 12 is internally provided with a distance counter 17 and a station section counter 18, and as shown in FIG. 2, the distance counter 17 and the station section counter 18 are respectively reset by initialization, and the operation system setting device 13 is set. The operation system number is fetched and stored in an internal register (or memory) (S 1 ).

距離との差、つまり測定誤差を求める（Ｓ8）。It is checked whether the vehicle has started to travel (S 2 ), and when the travel signal is received from the distance signal generator 16 (S 3 ) after the start of travel, the distance counter 1
Step 7 is performed (S 4 ), and it is checked whether the door open signal is input (S 5 ). If not, the process returns to step S 3 and waits for a distance signal interrupt. When the door open signal is input, the inter-station distance (traveling distance) is calculated from the count value of the distance counter 17 at that time and the preset wheel diameter at the start of use to measure the inter-station distance. (S 6 ). Further, the correct distance between the adjacent stations which are currently traveling is read from the memory 11 from the count value of the station section counter 18 and the set operation system number (S 7 ), and the difference between the correct station distance and the measured station distance is read. That is, the measurement error is obtained (S 8 ).

If it is within the specified value, the display 19 displays "Normal" (S
10), in the case of less than the prescribed value indicated as "replacement" is displayed on the display unit 19 (S 11). That is, if the wheel wears and the diameter becomes smaller, the number of pulses generated from the speed generator 15 increases even at the same traveling distance, and the distance between measurement stations becomes larger than the correct distance between stations. It is judged that it has become less than the value and it is displayed that replacement is required.

Reset the (S 13), by stepping the station interval counter 18 returns to step S 2 (S 14). Therefore, the distance between stations is measured for the next station section, the error is calculated, and it is similarly determined whether the difference is within the specified value. It should be noted that the distance signal generating unit 16 counts or calculates the travel distance, and the measured travel distance is calculated by the microprocessor 12 for each door open signal.
Alternatively, the distance signal generator 16 may be reset after being taken into.
