Description

Subway carriage overload warning control setup

Technical field

The utility model is particularly related to a kind of subway carriage overload warning control setup.

Background technology

Along with increasing urban development subway, subway becomes the important traffic pivot Handcuffs in the modern city.Particularly along with the increasing of urban population and private car, city traffic is supported and is stopped up and make the people who takes subway more and more, and the overload phenomenon often takes place.Owing at present the overload in the subway carriage is not had the actv. measure of control, overload problems is difficult to solve, and exists owing to crowd, trample the potential safety hazard that can cause the personal casualty grave accident.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, providing a kind of can report to the police and take corresponding measure of control subway railway car overload, prevent passenger's blindly " squeezing oneself into a croweded bus ", with in the reasonable scope with number of passengers control in the compartment, guarantee personal safety, eliminate accident potential, guarantee the subway carriage overload warning control setup of the normal operation of subway train.

The utility model is achieved in that it is provided with the check weighing unit in the subway carriage bottom, described check weighing unit is connected by the signal wire (SW) control unit indoor with being positioned at locomotive control, be provided with the alarm unit on the compartment doorframe, described control unit mouth is connected with opening and closing apparatus for vehicle door with the alarm unit by signal wire (SW) respectively.

The utility model has the advantages that: can when compartment load overloads, send alarm, make car door be in the caution closed condition simultaneously, prompting is personnel, train operator and platform staff by bus, prevent passenger's blindly " squeezing oneself into a croweded bus ", with in the reasonable scope with number of passengers control in the compartment, thereby prevent because the grave accident of the personal casualty that overload causes guarantees that train normally moves.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a circuit block diagram of the present utility model.

Among the figure: locomotive control chamber 1, subway carriage 2, compartment doorframe 3, alarm device 4, opening and closing apparatus for vehicle door 5, check weighing unit 6, control unit 7.

The specific embodiment

As shown in the figure, be provided with check weighing unit 6 in subway carriage 2 bottoms, described check weighing unit 6 is connected with the control unit 7 that is positioned at locomotive control chamber 1 by signal wire (SW), be provided with sound and light alarm suggestion device 4 and opening and closing apparatus for vehicle door 5 on compartment doorframe 3, described control unit 7 mouths are connected with opening and closing apparatus for vehicle door 5 with sound and light alarm suggestion device 4 by signal wire (SW) respectively.

When personnel in the compartment and article reach the overload setting value, give control unit 7 signals by check weighing unit 6, after judging, control unit 7 outputs signal to sound and light alarm cue circuit 4, make sound and light alarm cue circuit 4 send sound and light alarm, prompt passengers compartment load exceedance, give door contact interrupter control setup 5 signals simultaneously, make car door be in semi-closed state, after the passenger that gets on the bus after in the subway compartment 2 gets off, check weighing unit 6 is given control unit 7 signals again, control unit 7 judges that when load weight was lower than the overload setting value, the output control signal was given sound light alarming circuit 4, makes it stop to report to the police; Give opening and closing apparatus for vehicle door 5 control signals simultaneously, make closing of the door, the driver is the clean boot train again.
