Abstract

A navigation system for subway passenger seats is characterized by comprising sensors (1) mounted on the subway passenger seats, signal amplifying comparison circuits (2), A/D (analog/digital) converting circuits (3), a counter (4) and a displayer (5). Signal output ends of the sensors (1) are connected with input ends of the corresponding signal amplifying comparison circuits (2), output ends of the signal amplifying comparison circuits (2) are connected with input ends of the corresponding A/D converting circuits (3), output ends of the A/D converting circuits (3) are connected with an input end of the counter (4) in each compartment, and the counter (4) in each compartment is connected with the displayer (5) at the position of a subway station corresponding to the compartment through a vehicular network. The navigation system for the subway passenger seats enables passengers to know the number and positions of vacant seats in a train, so that the passengers can find the vacant seats for rest, resource utilization ratio is increased, and load of the train is more balanced.

Description

Subway passenger-seat navigationsystem

Technical field

The utility model relates to a kind of subway technology; Especially a kind of can predicting in advance has or not vacant seat and vacant seat quantity so that the passenger can be in time to the navigationsystem that has the compartment, vacant place to flow in order, specifically a kind of subway passenger-seat navigationsystem that can improve the subway resource utilization in the subway carriage.

Background technology

At present, subway has become city walking-replacing tool easily gradually, and the convenience of subway and the welcome that fast receives a lot of city dwellers greatly facilitate people's trip.But a lot of passengers select directly to wait for bus at the subway ENTRANCE, and this has just caused the part compartment no one that has vacant position to sit, and the part compartment is overstaffed, so just " waste " resource of rest.Because passenger and station staff can't estimate respectively to save compartment personnel's situation intuitively, can only rule of thumb dredge, remind the passenger to the few compartment shunting of expectation personnel, have bigger blindness.

Summary of the invention

The purpose of the utility model is that the part compartment often to occur overstaffed to existing same row subway; And room, part compartment is more; By bus personnel can't intuitively understand the problem that respectively saves compartment vacant scats situation, designs a kind ofly can show that in real time next time incoming train respectively saves compartment vacant scats situation so that let the passenger can be in time to the orderly mobile subway passenger-seat navigationsystem in vacant scats compartment is arranged in the subway district that waits.

The technical scheme of the utility model is:

A kind of subway passenger-seat navigationsystem; It is characterized in that it by be installed in sensor 1 on the subway seat, signal amplifies comparator circuit 2, A/D change-over circuit 3, counting machine 4 and read-out 5 and forms; The signal output part of described each sensor 1 links to each other with the input end that cooresponding signal amplifies comparator circuit 2; The mouth that each signal amplifies comparator circuit 2 links to each other with the input end of cooresponding A/D change-over circuit 3; The input end of the counting machine 4 in the mouth of each A/D change-over circuit 3 and the every joint compartment links to each other, and every joint compartment counting machine 4 links to each other through the wait read-out 5 at corresponding car position place, district of In-vehicle networking and subway station passenger.

2, subway passenger-seat navigationsystem according to claim 1 is characterized in that described sensor 1 is piezoelectric transducer or capacitance-type sensor.

The beneficial effect of the utility model:

The subway passenger navigation system of the utility model lets the passenger can know room number and the position in room on this train, makes things convenient for the passenger to find the room to have a rest easily, has improved resource utilization, makes the load balance more of train.

The utility model is simple in structure, is easy to realize.

Description of drawings

Fig. 1 is the structural representation at seat that the sensor of the utility model has been installed.

Fig. 2 is that the seating state of the utility model detects schematic diagram.

Fig. 3 is that the system of the utility model forms functional block diagram.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Shown in Fig. 1-3.

A kind of subway passenger-seat navigationsystem; It is made up of the sensor 1, signal amplification comparator circuit 2, A/D change-over circuit 3, counting machine 4 and the read-out 5 that are installed on the subway seat; As shown in Figure 3; Sensor 1 wherein can adopt piezoelectric transducer, also can adopt capacitance-type sensor, and sensor 1 is as shown in Figure 1 in the installing condition at seat; The signal output part of described each sensor 1 links to each other with the input end that cooresponding signal amplifies comparator circuit 2; The mouth that each signal amplifies comparator circuit 2 links to each other with the input end of cooresponding A/D change-over circuit 3, and the input end of the counting machine 4 in the mouth of each A/D change-over circuit 3 and the every joint compartment links to each other, and every joint compartment counting machine 4 is continuous through the wait read-out 5 of distinguishing corresponding car position place of In-vehicle networking and subway station passenger.It is as shown in Figure 2 that the seating state of the utility model detects schematic diagram, when the passenger sits down, and electric current of pressure sensor 1 output; Amplify comparator circuit 2 through signal and integrate force value of amplification output, establish voltage ratio, through A/D change-over circuit 3 output digital signals with former; If establish then output signal 1 of voltage greater than former, otherwise output signal 0, this signal carries out the plus-minus of signal through the counting machine in every joint compartment; Send on the LCDs in each cooresponding district that waits, joint compartment, the next stop through in-vehicle communication system again; Show that on LCDs each compartment of subway has or not the room, and the number in room, like this; The passenger who waits in this district that waits knows promptly whether have vacant position in the compartment that waits and the vacant situation in other compartment, and the broadcasting studio, station also can shunt according to the room situation voice reminder passenger on the train of receiving.In addition, also the telltale that can show this joint compartment vacant scats can be installed on the external door of every joint vehicle, so as with the station on the vacant scats that shown corresponding.

The utility model does not relate to part and all can adopt prior art to realize or identical with prior art like control circuit, signal processing circuit, signal transmission form etc.
