Description

The utility model relates to measuring equipment and is intended to account for the volume of traffic by passenger vehicles, such as bus.

Various devices are known for counting the number of persons passing (entering and leaving) through a given area, based on optical or ultrasonic methods of functioning, or on methods using rug switches.

In particular, an anti-fraud system that controls access to public transport is known (patent RF 2713805, G 07 B 15/00, G 07 C 9/00, 06/16/1995). The system is installed at the exit of the station to the vehicle and includes three zones: payment, control and control passage. The payment zone is equipped with prepaid recognition tools. The control zone is equipped with various detectors: a pressure sensitive rug; active infrared barrier that determines the movement; passive infrared barrier separating passengers from their suitcases;

ultrasonic for counting moving objects. Data from the detectors are compared in real time by a microprocessor, which determines the number of passengers and determines the need to close the passage. The disadvantage of this system is the impossibility of its use directly on the vehicle.

A counter of passers-by is also known (patent US 4122331, G 07 С 9/00, 1978), including a sensor made in the form of a rug made of elastic dielectric material and having two areas with the same sensitive elements placed in them in the form

normally open independent switches and many resistors electrically connected to the switches. The sensor is electrically connected through a signal generation unit (converting analog signals to digital and their preliminary processing) with a control and monitoring unit with memory. The switches are sequentially closed by the pressure of the feet of passers-by, from which the electrical resistance decreases. The signal count is kept taking into account the direction of movement of passers-by. The known device as structurally close to the claimed accepted as a prototype, although it can only be used at stations. Its disadvantage: it is not suitable for use on a vehicle and, in addition, it does not have a sufficiently high reliability.

The objective of the utility model was to create a device for accounting for the number of passengers carried by public transport, higher operational reliability due to simplification of the design due to a change in the principle of functioning of the sensitive elements of its sensor.

To solve the problem with the achievement of the specified technical result, the device for recording the number of passengers carried by public transport contains a sensor triggered by pressing the passenger’s foot, the sensitive elements of which are normally open contacts, are placed in two areas of the mat made of elastic dielectric material and are electrically connected by means of a forming unit signals with a counting control unit with memory.

A distinctive feature of the proposed model is that the device’s sensor contains two two-electrode sensitive elements, one of the electrodes of which is made in the form of a plate mounted with the possibility of overlapping the working section of an autonomous

parts of the mat and resting on elastic elements, another electrode is made in the form of a wire located under the plate with a gap between its parts, and two load-bearing sensitive elements of the area of the mat are made of autonomous parts with the possibility of placement and fixing on the steps of the vehicle.

To enable rational implementation of the device, the electrode-wire of each sensitive element of its sensor is made in the form of a single-layer loop laying.

To simplify the manufacture of the rug, the electrode-wire sections of each sensitive element of its sensor between the loops are made rectilinear, for example, with a longitudinal orientation.

To simplify the design, the elastic elements of each sensitive element of the sensor of the device are made of an elastic material in the form of a parallelepiped or in the form of plate springs laid along the electrode-wire from its two sides.

To increase maintainability and simplify manufacturing, the autonomous parts of the sensor mat are made detachable.

To increase reliability, each autonomous part of the device sensor mat is provided with a protective element made in the form of a L-shaped plate with holes for mounting screws, and each autonomous part of the mat has a longitudinal ledge for interaction with the protrusion of the L-shaped plate.

To increase the convenience during operation, the counting and control unit of the device is equipped with a microprocessor, a display and a timer with an autonomous power supply.

The utility model is illustrated by drawings, which depict:

The utility model is a device for recording the number of passengers transported by public transport mainly by bus. It consists of a sensor 1, a shaper 2 (signal generation unit) and a counting control memory unit 3 (FIGS. 1 and 2). The sensor 1 contains two identical sensing elements 4, located in two made of elastic dielectric material, for example rubber, autonomous parts 5 and 6 of the mat 7. Each sensitive element 4 is made of two electrodes - the electrode plate 8 and the electrode wire 9 with a single loop laying with a gap (i.e. with rectilinear longitudinally oriented sections 10 and loops 11). A spiral shape 12 of the electrode-wire 9 is also possible (FIG. 3). The electrode plate 8 is supported by elastic elements 13 or 14 and is located above the electrode wire 9 with a gap h (Figs. 4 and 5). The elastic elements 13 can be made in the form of a parallelepiped, for example of rectangular cross-section, made of foam or other similar material. The elastic elements 14 (their other modification) can be made in the form of plate steel springs of arched shape with supporting edges 15. The elastic elements 13 and 14, the electrode wire 9 and the electrode plate 8 are located respectively in the lower recesses 16, 17 and 18 and the upper recesses 19 autonomous

parts 5 and 6 of the mat 7. Each autonomous part 5 and 6 of the mat 7 has a stepped connector 20 and is equipped with a means 21 for mounting respectively on the inner steps 22 and 23 (lower and subsequent) of the vehicle 24. The means 21 is made in the form of several screws 25 ( located vertically) and 26 (located horizontally), and two protective elements 27 in the form of longitudinal L-shaped plates (one for each part of the mat). The plate 27 has passage holes 28 for screws 26 and, with its protrusion 29, interacts with the longitudinal ledge 30 of the corresponding autonomous parts 5 and 6 of the mat 7 (Fig. 3). In steps 22 and 23, threaded holes 31 and 32 are made for screws 25 and 26, respectively, and in the autonomous parts 5 and 6 of the rug 7, through holes 33 for screws 25 are made. The autonomous parts 5 and 6 of the mat 7 have anti-skid corrugations on its outer surface 34 35. Electrodes-wires 9 directly, and electrodes-plates 8 with the help of wires 36 soldered to them at the output of the sensor 1 are connected respectively to terminals 37, 38, 39 and 40, to which respectively the communication wires connected into the cable from the input of the shaper 2 are connected ( specified terminals may located directly at the input of the former 2, and wires 36 and 9 - to be part of the cable). As shaper 2, the equipment usually used for such purposes can be used, which provides digital outputs with the required parameters (amplified and distinguished by the order of arrival, corresponding to the direction of movement of passengers — by input and output). The output of the shaper 2 is connected to the input of the counting control unit 3.

The counting and control unit 3 (Fig. 7) may contain a microprocessor 41 with memory 42, a display 43, a power supply 44, and a timer 45 with an autonomous power supply 46. In addition, it may contain means of protection against unauthorized access to information, for example

an identifying module (not shown in the block diagram), and the required housing design.

The proposed device operates as follows. The sensor 1 is fixed (autonomous parts 5 and 6 of its mat 7 on the inner steps 22 and 23 of the vehicle 24, for example, a bus) by means of fasteners 21 and provide its electrical connection with the counting and control unit 3 through the shaper 2, which is connected to the unit power 47 (for example, a car battery through a current transducer) (Fig.1 and 7). At stops at the entrance to the bus, the passenger sequentially first steps on the autonomous part 5 of the mat 7, and then on its part 6 (the outline of track 48 from his shoes with the direction of movement along arrow 49 in the plan of FIG. 1). From the force P of his leg, the distance h (Fig. 4) between the electrode-plate 8 and the electrode-wire 9 decreases to zero, i.e. a circuit is closed, the voltage from the power supply 47 is supplied to the input of the former 2 and is removed from its outputs in the form of digital signals with transmission to the inputs of the unit 3 for subsequent processing. When leaving the bus, the passenger sequentially first steps on the autonomous part 6 of the mat 7, and then on its part 5 (trace of the track 50 from his shoes with the direction of movement along arrow 51 in the plan of figure 1). In this case, the sensing elements 4 function as described above. The analog signals of converters 4 by shaper 2 are converted to digital (and also compared and amplified) and processed by block 3. Upon request, block 3 provides information on the number of passengers carried at a fixed point in time, including the date, as well as on the number of passengers in the bus compartment ( during working hours of the provision of transport services).

The proposed utility model expands the arsenal of funds for accounting for passenger traffic and fiscal control of carriers.
