This exempts the bus stewards from the trouble of reporting stops along the route and facilitates the passengers who are not familiar with the route. In our country, there have been relevant documents about the design of stop-reporting device. But from the whole, their designs have the deficiency of comparative single function, and inability to make full use of the resources of Monolithic machine system to bring out the entire efficacy of the device in largest degree. This paper incorporating the technology of Monolithic machine, Pronunciation，temperature-measuring, radio data transmission and LCD, gives a new design which have not only the stop-reporting function, but also the temperature-measuring and character-indication functions. Thus it realizes the basic arrive, no matter the routes change or not; at the same time, it have the function of pre-reporting stops function of reporting stops: the buses of the whole city can report stops where they: at a certain distance before the stop, it can automatically and accurately report the stops without the driver pushing the button. At the time of bringing convenience to the passengers, it also makes the driver m
