Abstract

The utility model relates to a dynamic railroad track scale which can determine the direction of a coming vehicle, belonging to a dynamic rail device that determines the direction of the coming vehicle by displacing a weighing rail. The utility model primarily settles such technical problems related to prior weighing rails as expensive installation of a recognizer and easy to encounter errors in installation. The dynamic railroad track scale that determines the direction of the coming vehicle includes a base and two rail weighing sensors and an electronic weighting system that determines the direction of the coming vehicle and includes an amplifier, an analog to digital converter circuit, a calculation recognizer and a peripheral equipment, wherein, the two rail weighing sensors are misplaced on the base and are put in relation to an approach rail; the output terminal of each rail weighing sensor connects to the input terminal of the amplifier to form independent weighing signal which is sent to the calculation recognizer by means of the amplifier and the analog to digital converter circuit in order to determine the direction of the coming vehicle and weigh the vehicle.

Description

Can judge the dynamic railway truck scale of direction of traffic

Technical field

The utility model relates to a kind of dynamic railway truck scale that can judge direction of traffic, and it belongs to a kind of and utilizes dislocation to settle the weighing track to judge the dynamic track device of direction of traffic.

Background technology

Existing dynamic railway truck scale is because its two weighing tracks are to align to be placed on the basis, in order to discern the direction that vehicle is made a return journey, also need switching signal device and logic control element be installed on approach rail and weighing track, devices such as automatic vehicle identification device, scanner perhaps are installed.These devices are installed are not only wasted fund, and make mistake easily, cause identification error, influenced the efficient of dynamic railway truck scale.

Summary of the invention

The purpose of this utility model is to solve installation recognizer expense height, the technological difficulties that easily make mistake of existing weighing track existence and a kind of dynamic railway truck scale that can judge direction of traffic that any attachment device need not be installed, not only economize on the use of funds but also can not make mistakes is provided.

The utility model for the technical scheme that solves above-mentioned technological difficulties and adopt is: the dynamic railway truck scale that can judge direction of traffic, it comprises basis and two rail mounted LOAD CELLS, wherein: it also comprises one by amplifier, analog to digital conversion circuit, calculate the weighing of recognizer and peripherals formation and the electronic system of judgement direction of traffic, article two, the dislocation of rail mounted LOAD CELLS front and back is placed in upward basic and aligns with approach rail, the output terminal of each bar rail mounted LOAD CELLS links to each other with amplifier input terminal, form independently weighing-up wave, this weighing-up wave is through amplifier, analog to digital conversion circuit enters and calculates in the recognizer, to judge the direction that vehicle enters and the weight of weighing vehicle.

Described rail mounted LOAD CELLS can also be substituted by weighing track, weighting platform and LOAD CELLS, dislocation is placed on the table top of weighting platform before and after the weighing track, table top at the weighting platform of settling the weighing track has LOAD CELLS, and LOAD CELLS is fixed on the basis.

The metering method of this dynamic railway truck scale is any one in a metering method, bogie metering method or the car load metering method.

Described calculating recognizer is any one in computing machine or the single-chip microcomputer.

Described peripherals is display, communication interface and printing device.

Because the utility model has adopted dislocation before and after weighing track or the rail mounted LOAD CELLS is placed in technical scheme on the basis, at first the force signal that is subjected to of the weighing track of pressurized is transferred to the electronic system of weighing and judgement direction of traffic, carry out weighing with the direction of judgement vehicle ' and to it, therefore compare with background technology, the utlity model has and to install that any attachment device just can be judged vehicle heading, advantage such as not only economize on the use of funds but also can not make mistakes.

Embodiment:

The utility model will be further described below in conjunction with drawings and Examples.

As Fig. 1, Fig. 2 and shown in Figure 5, the dynamic railway truck scale that can judge direction of traffic in the present embodiment, it comprises 2 and two the rail mounted LOAD CELLS 1 in basis, wherein: it also comprises one by amplifier 8, analog to digital conversion circuit 9, computing machine 10 and by display 11, communication interface 12, weighing that the peripherals that printing device 13 is formed constitutes and the electronic system of judging direction of traffic, article two, the dislocation of rail mounted LOAD CELLS 1 front and back is placed on the basis 2 and with approach rail 3 and aligns, the output terminal of each bar rail mounted LOAD CELLS 1 links to each other with the input end of amplifier 8, form independently weighing-up wave, this weighing-up wave is through amplifier 8, analog to digital conversion circuit 9 enters in the computing machine 10, to judge the direction that vehicle enters and the weight of weighing vehicle.4 is wheel among the figure, and 5 is car body.

As Fig. 3, Fig. 4 and shown in Figure 5, the dynamic railway truck scale that can judge direction of traffic among the another embodiment of the utility model, it comprises 2 and two the weighing tracks 1 in basis, weighting platform 7 and LOAD CELLS 6, article two, the dislocation of weighing track 1 front and back is placed on the table top of weighting platform 7, table top at the weighting platform 7 of settling weighing track 1 has LOAD CELLS 6, LOAD CELLS 6 is fixed on the basis 2, it also comprises one by amplifier 8, analog to digital conversion circuit 9, computing machine 10 and by display 11, communication interface 12, weighing that the peripherals that printing device 13 is formed constitutes and the electronic system of judging direction of traffic, the output terminal of the LOAD CELLS 6 of the same side links to each other with the input end of amplifier 8, form independently weighing-up wave, this weighing-up wave is through amplifier 8, analog to digital conversion circuit 9 enters in the computing machine 10, to judge the direction that vehicle enters and the weight of weighing vehicle.3 is approach rail among the figure, and 4 is wheel, and 5 is car body.

Computing machine in the foregoing description can also substitute with single-chip microcomputer.

The metering method of the dynamic railway truck scale in the foregoing description is a metering method.The metering method of the utility model dynamic railway truck scale can also be any one in bogie metering method or the car load metering method.

Principle of work of the present utility model is: as depicted in figs. 1 and 2, when vehicle by C to the D direction running when the dynamic railway truck scale, A sidecar wheel 4 at first is pressed onto on the weighing track 1 of A side, the LOAD CELLS of A side is stressed to be increased earlier.After vehicle continued to travel magnitude of misalignment, the wheel 4 of B side was pressed onto on the weighing track of B side.

Otherwise, when vehicle by D to the C direction running when the dynamic railway truck scale, B sidecar wheel 4 at first is pressed onto on the weighing track 1 of B side, the LOAD CELLS of B side is stressed to be increased earlier.After vehicle continued to travel magnitude of misalignment, the wheel 4 of A side was pressed onto on the weighing track of A side.

Therefore, if the LOAD CELLS output signal that the LOAD CELLS output signal of A side increases prior to the B side increases, then can be judged as vehicle is to the D direction running from C.On the contrary, if the LOAD CELLS output signal that the LOAD CELLS output signal of B side increases prior to the A side increases, then can be judged as vehicle is to the C direction running from D.

When A sidecar wheel and B sidecar are taken turns when all having gone up the weighing track, the LOAD CELLS of A side and B side LOAD CELLS output signal and the increase value with regard to the weight of corresponding axletree or vehicle.Measure its increase value and show the weighing function of just having finished dynamic railway truck scale.
