Abstract
The utility model discloses a reminder for reminding passengers of bus stopping at station, which belongs to car signal system. The utility model mainly solves the problem of communications between the bus drivers and the passengers getting off. The technical proposal is that a end of a ganged switch K1 is connected with one end of a buzzer F; b end is connected with one end of a relay J and one end of a bulb D; the other end of the buzzer F is connected with c end of a normally closed single-linkage switch and connected with the other end of the relay J and the other end of the bulb D; a circuit where a contact JJ of the relay J is on is connected with the ganged switch K1 in parallel. When passengers press down the stop button near the seats or the door, K1 switches the light box on; when the door is open when reaching the station, K2 is switched on, the whole circuit is cut, the light box is power off and then K2 restores to closed state. The utility model is suitable for buses.
Description
Affiliated technical field
The utility model relates to a kind of assistant product of public transport means, particularly a kind of bus arrival parking reminding device.
Technical background
In daily life, everybody sees this phenomenon often: after bus arrival opened the door, whether the passenger who does not get on or off the bus, or be generation for fear of above-mentioned situation went up nobody when waiting for bus when the driver sees to arrive at a station, must loud inquiry have the passenger to get off.So both increased the weight of driver's work load, also brought inconvenience for driving.
Summary of the invention
For overcoming the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of signalling apparatus that can remind the bus driver to stop.
Main technical schemes of the present utility model is that a end of coupled twin switch K1 and the end of buzzer phone F join, one end of b end and relay J joins, and and the end of bulb D join, the c end of the other end of buzzer phone F and normally closed single connection plane switch K2 joins, and and the other end of relay J, the other end of bulb D join, the circuit at the JJ place, contact of relay J is in parallel with coupled twin switch K1.
K1 is a coupled twin switch, K1 closure when the passenger presses the button, and relay J work, buzzer phone F rings, and lamp box is bright; When passenger's release button, buzzer phone F stops to ring, and lamp box continues to light.Arrive at a station and stop when opening the door, touch switch K2, circuit disconnects, the contact JJ disjunction of relay J, lamp box extinguishes, and K2 recovers closure state subsequently.
The beneficial effects of the utility model are: owing on the bus this parking signal apparatus is arranged, made things convenient for the information transmission between chaufeur and the passenger, alleviated the work load of chaufeur, helped traffic safety.And this apparatus structure is simple, and cost is low, and is easy to operate, also can exempt the oil plant waste that unnecessary parking causes, and has higher utility.
Description of drawings
Be elaborated below in conjunction with accompanying drawing.
Accompanying drawing is schematic circuit diagram of the present utility model.
Among the figure, the k1. coupled twin switch; F. buzzer phone; J. relay; D. bulb; K2. normally closed single connection plane switch; JJ. relay contact.
The specific embodiment
Other element of bulb D and circuit is installed in the lamp box in chaufeur the place ahead, and with " parking of please arriving at a station " printed words, stop button coupled twin switch K1 in other words is arranged on by near and the exit door of passenger-seat on the lamp box.Connect with lead between stop button and the lamp box.This stop button can be provided with parallel with one another a plurality of.Normally closed single connection plane switch K2 is arranged on the exit door place.
Be connected to the 24V direct current (DC) in the drawings, circuit layout is as follows: a end of coupled twin switch K1 and the end of buzzer phone F join, one end of its b end and relay J joins, and and the end of bulb D join, the c end of the other end of buzzer phone F and normally closed single connection plane switch K2 joins, and and the other end of relay J, the other end of bulb D join, the circuit at the JJ place, contact of relay J is in parallel with coupled twin switch K1.
When the passenger presses stop button, coupled twin switch K1 closure, relay J work, buzzer phone F rings, and lamp box is bright, and the prompting driver sets out in advance to make arrangements has the people to get off; When passenger's release button, buzzer phone F stops to ring, and lamp box continues to light.Arrive at a station and stop when opening the door, car door touches normally closed switch K2, and K2 opens, and circuit disconnects, the contact JJ disjunction of relay J, and lamp box extinguishes, and K2 recovers closure state subsequently.This device moves in circles with this principle and step work.
Claims (1)
1, a kind of bus arrival parking reminding device, it is characterized in that: a end of coupled twin switch K1 and the end of buzzer phone F join, one end of b end and relay J joins, and and the end of bulb D join, the c end of the other end of buzzer phone F and normally closed single connection plane switch K2 joins, and joins with the other end of relay J, the other end of bulb D; The circuit at the JJ place, contact of relay J is in parallel with coupled twin switch K1.
