The logic signal from R is amplified by intensifiers a and 6b. When the argument weight signals 5'a and 5'b become larger than the reference value,
The output signal of the shaping circuit 6a turns on '8' after a little delay, and the output signal of the shaping circuit 6b becomes blurry.When the output signal 6'a of the shaping circuit 6a becomes bright, the AND circuit 7a outputs a flip-flop output signal. Because the crab's body is so strong, the output signal 'a'

, becomes a day. Next is logic book circuit 7! The output signal of the shaping circuit 6 becomes HI, but the flip-flop 8
Since the output signal 8' of a is Z, the output signal r is 1. For this reason, the flip-flop bit b is not set, so the output signal register '0 is L. The logic mirror circuit ga is delayed by the delay circuit ga when the output of the logic thin circuit becomes day ``The output ge becomes day''. When the wheel passes the logic weight detector eagle L and the pirate Since the output signal of the inverting circuit group 3 becomes day, the output signal of the logical product circuit Kamele a is outputted. This signal indicates that the wheel 2 has passed from left to right. This signal is input to the processing unit and the peak holder is also input to the processing unit.
After the data processing is done, the Topeak holders are reset and prepared for the next data. When the vehicle approaches from the right to the left, the wheel weight detector turtle R "After a short delay, the weight signal from the wheel load detector turtle 1 is amplified by the intensifiers 5a and 6b.

The logic type circuit 7b outputs the output signal 7b of the flip-flop crab a when the output signal t'b of the shaping circuit b becomes day.
Is it a logical bran circuit? b output signal? When 'b' becomes the day, ~ is set and the output signal 'b, becomes the day. Next, the logic book circuit 7a receives the output signal 6'a of the shaping circuit 6a,
Since the output signal 8'bo of flip-flop crab b is L,
The output signal 7ra is Z. Therefore, since the flip-flop a is not set, the output signal 8'a is at L level. In the AND circuit gb, the output 6'a of the AND circuit 6a is H.
Then, the output 9'b becomes 1 and is delayed by the delay circuit 10b.

When the wheels pass through the logical weight detectors 4L and 4R, the AND circuit 11b outputs an output signal 11'b since the output signal 13' of the inverting circuit 13 becomes positive. This signal is wheel 2
This indicates that it passed from right to left. When this signal is input to the processing unit 15, the processing unit 15 inputs the logical weight values held in the peak holders 14a, 14b, performs data processing, and then the peak holders 14a, 14b are reset. Prepare for the next data. FIG. 2c shows a case where the wheel 2 approaches from left to right, stops on the wheel load detectors 4L and 4R, and returns.

When the wheel 2 approaches, the shaping circuit 6a? The output signals 6'a and 6'b of 6b become digits, and the flip-flop 8a
is set. When the wheel 2 returns after stopping on the wheel load detectors 41 and 4R, the AND circuit 11a detects that the output signal 13' of the inverting circuit 13 is low, but the output signal 10'a of the delay circuit 10a is low. Therefore, the AND circuit 11a
The output signal gain 'a' is L. In other words, it shows that the wheels are not passing. Therefore, the wheel load values held by the peak retainer amounts 4a and 14M are not read. In this way, by installing the logical weight detector so that the left and right wheel load signals generated on the rail overlap, it is possible to track the wheels to be measured no matter how the direction of travel of the vehicle changes.
