PROBLEM TO BE SOLVED: To provide a monitor which can output an alarm signal if a vehicle stops in a position where two-way communication becomes impossible as well as a tire air pressure monitoring system and a control program.SOLUTION: In a monitor 1 which is provided on a tire 3 of a vehicle c and sends a request signal for requesting information of pneumatic pressure to a detection device 2 wirelessly transmitting a pneumatic pressure signal obtained by detecting the pneumatic pressure of the tire 3 and monitors the pneumatic pressure of the tire 3 by receiving the pneumatic pressure signal sent from the detection device 2 in accordance with the request signal, it comprises a request signal transmission part which wirelessly transmits the request signal to the detection device 2 if the vehicle c stops, a pneumatic pressure signal receiving part which receives the pneumatic pressure signal sent from the detection device 2 in accordance with the request signal and an output part which outputs the warning signal for warning inside the vehicle when not receiving the pneumatic pressure signal in accordance with the request signal if sending the request signal.SELECTED DRAWING: Figure 1
【課題】双方向通信が不能になる位置で車両が停止した場合に警告信号を出力することができる監視装置、タイヤ空気圧監視システム及び制御プログラムを提供する。【解決手段】車両Cのタイヤ3に設けられ、タイヤ3の空気圧を検出して得られる空気圧信号を無線送信する検出装置2へ空気圧の情報を要求するための要求信号を送信し、要求信号に応じて検出装置2から送信される空気圧信号を受信してタイヤ3の空気圧を監視する監視装置1は、車両Cが停止した場合、要求信号を検出装置2へ無線送信する要求信号送信部と、要求信号に応じて検出装置2から送信される空気圧信号を受信する空気圧信号受信部と、要求信号を送信した場合、要求信号に応じた空気圧信号を受信しないとき、車両内に警告するための警告信号を出力する出力部とを備える。【選択図】図1
