Definitions

  • the NG signal from the first determination circuit is input to the exclusive logic circuit 27, and when it is detected that only one of the four wheels is at a low pressure, a positive logic signal H is output.
  • This exclusive logic circuit connects the output lines of the four first decision circuits 18 in parallel to the inputs of two exclusive OR gates, as shown in FIG. 3, for example. It can be configured by connecting the output of a logical OR gate to another exclusive OR gate whose input is inverted.
  • the square wave oscillation circuit 28 is always operated at a frequency of several Hz to generate a square wave.
  • the buzzer circuit 29 is operated by receiving the output H from the exclusive logic circuit 27 and the square wave, The buzzer alarm 30 sounds the buzzer intermittently at several Hz.
  • light emitting elements corresponding to each mounted tire are arranged so as to correspond to the arrangement position of each tire, and based on a judgment output signal from the first judgment circuit. It is also possible to blink only the light-emitting display element associated with the tire determined to have an internal pressure abnormality.
