The invention relates to a reminding device for preventing a taxi from carrying people for many times. The device comprises a box body, a magnetic induction body, a magneto-dependent sensor b, an amplifier B, a relay K, a resistor R, a capacitor C, a diode D, a single chip microcomputer, a display screen, a power supply VCC, a power supply VSS1, a power supply VSS2 and a working power supply. Thedevice is characterized in that a sensor socket 1, a power socket, an indicator, a display screen socket and a sensor socket 2 are sequentially arranged on a panel of the box body from left to right,emitters of magneto-dependent sensors b1, b2, b3, b4 and b5 are connected with the power supply VCC together, a normally-closed end moving contact and a normally-closed end static contact of an outputcontact J of K are connected with the single chip microcomputer and the power supply VCC respectively, the single chip microcomputer is connected with the display screen, the display screen fixed onthe left front portion in a cab displays words of not carrying people for many times after the taxi carries people for the first time, and the device is easy to manufacture, uses few elements, is stable in working performance, guarantees rights, interests, time and safety of passengers, and has a very considerable wide application prospect in some small and medium-sized cities.

    本发明专利一种出租车勿多次载人提醒装置,包括一盒体,还包括磁感应体、磁敏传感器b、放大器B、继电器K、电阻器R、电容器C、二极管D、单片机、显示屏、电源VCC、VSS1、VSS2、工作电源,其特征在于,所述盒体的面板从左向右依次设置传感器插座1、电源插座、指示器、显示屏插座、传感器插座2,所述磁敏传感器b1、b2、b3、b4、b5的发射极一同与电源VCC连接,K的输出触点J常闭端动静触点分别连接单片机和电源VCC,单片机输出连接显示屏,形成出租车第一次载人后司机室内左前方固定的显示屏显示“勿多次载人”字样,本发明专利制作简单,使用元件少,工作性能稳定,确保乘客的权益、时间和安全,在一些中小城市广泛应用前景非常可观。
