To achieve these goals, the utility model can reach by following measures:
A kind of school bus alarming device, comprise power supply, relay, parking light switch, Der Blink und Abblendschalter, closed type magnetic induction switch and indicator lamp, it is characterized in that the closed type magnetic induction switch, relay, Der Blink und Abblendschalter, parking indicator lamp group, parking light switch and power supply are in series to consist of the circuit of warning that stops, power supply, parking light switch, Der Blink und Abblendschalter, relay and preparation parking indicator lamp group consist of prepares the circuit of warning that stops, wherein the mouth of Der Blink und Abblendschalter is connected with the common port of relay, preparation parking indicator lamp group is connected with the normally closed contact of relay, and parking indicator lamp group is connected with the open contact of relay.
As preferably, described preparation parking indicator lamp group is formed in parallel by four yellow indicator lamps, and parking indicator lamp group is formed in parallel by four red indicating lights.
As preferably, the frequency of operation of described Der Blink und Abblendschalter is 1-2Hz, the experiment proved that, frequency of operation the most easily is identified by the human eye at the wigwag of 1-2Hz, therefore adopt it outwards to export and prepare the signal of warning that stops, in addition, in order further to improve the effect of warning, be provided with loud speaker in the Der Blink und Abblendschalter, be used for the signal that sounds warning simultaneously.
The utility model in use, described indicator lamp is fixed on outside the school bus car body, the closed type magnetic induction switch is installed on the car door of school bus, be used for the induction car door opening, closing signal, and then realization is to the triggering of relay mode of operation, during driving of school bus, if the driver is prepared to stop, and closed parking light switch, frequency with 1-2Hz after Der Blink und Abblendschalter powers on is exported high level, this moment, the normally closed contact owing to relay was connected with preparation parking indicator lamp group, power supply, parking light switch, Der Blink und Abblendschalter, relay and preparation parking indicator lamp composition prepare the circuit connection of warning of stopping, and four yellow parking lights that prepare send " will stop " signal with the glittering work of the frequency of 1-2Hz to vehicular traffic because powering on; When vehicle comes to a complete stop rear driver when opening passenger door, magnetic sensible switch on the passenger door is in and closes and state, the control end of relay is received the energizing signal of closed type magnetic induction switch and is started working, normally closed contact disconnects, open contact is connected, thereby four glittering work of red parking light (four yellow preparation parking lights quit work simultaneously) are sent " the up and down student of stopping " signal to vehicular traffic;
Der Blink und Abblendschalter can send the sound and remind the driver when preparation parking light or parking light work.
The utility model does not compared with prior art need existing vehicle circuit layout is carried out excessive change, has with low costly, rational in infrastructure, is specially adapted to school bus and uses, can Effective Raise school bus traffic safety etc. significant advantage.
