The invention relates to a device for reminding a taxi of not carrying people repeatedly. The device comprises a box body, and further comprises magneto-dependent sensors b, an amplifier Q, an electronic switch V, resistors R, capacitors C, a diode D, an NE555, a single chip microcomputer, a display screen and power supplies VCC, VSS1 and VSS2, and is characterized in that base electrodes of the magneto-dependent sensors b1, b2, b3 and b4, emitting electrodes of the Q and the V and a pin 1 of the NE555 are all connected with the VSS2, collectors of the magneto-dependent sensors b1, b2, b3 andb4 and the middle of the amplifier Q are connected with the R1, a collector of the Q is connected with a pin 2 and a pin 6 of the NE555, emitting electrodes of the magneto-dependent sensors b1, b2, b3, b4 and b5 are connected with the VCC, and a pin 3 of the NE555 is sequentially connected with the single-chip microcomputer and the display so as to form characters, namely no carrying people repeatedly, which is displayed on the display screen fixed on the front left portion of a cab after the taxi carries people once. The device is simple to manufacture, few in using element, stable in workingperformance, capable of ensuring rights, interests, time and safety of passengers, wide in application in certain small and the medium-sized cities and quite considerable in prospect.
