Abstract
A display and control device applied in the double-wind supply of locomotive comprises a first wind-supplying indicating light, a second wind-supplying indicating light and a pressure transducer; a pressure display module consisting of a single chip machine and signal collection device and the likes is arranged between the pressure transducer and the two wind-supplying indicating lights; and the wind-supplying indicating lights are controlled by the display module; when the pressure of the wind-supplying pipe is between 550 kPa and 620 kPa, the program of the pressure display module sends out voltage signal DC 24V, the wind-supplying indicating lights at the one end and two end are switched on; when the pressure of the wind-supplying pipe is less than 550 kPa or more than 620 kPa, the program of the pressure display module sends out voltage signal 0v, the wind-supplying indicating lights at the one end and two end are switched off. The utility model can precisely control the double-wind supply indicating light.
Description
Technical field
The utility model belongs to locomotive component, refers in particular to a kind of servicing unit of locomotive air pipeline, is mainly used in the electric locomotive air-supply pipeline system.
Background technology
Two-tube air feed is as the servicing unit of locomotive pipeline, and its reliability more and more is subjected to using the attention of department.At present, the two-tube air feed of locomotive shows to be realized by 1 pressure switch and 2 pilot lamp, and the variation of air feed pipe pressure opens and closes the pressure switch contact, controls the light on and off that two-tube air feed shows pilot lamp.According to the requirement that fortune dress skill is tested " 1999 " No. 201 files, air feed force pipe pressure is 600
-50 + 20, promptly during 550kPa≤air feed pipe pressure≤620kPa, two-tube air feed shows that pilot lamp is bright.And pressure switch is set after 1 value, utilizes its sluggishness can control two-tube air feed demonstration pilot lamp.As the pressure switch setting value is 620kPa, when air feed pressure rises to 620kPa and during greater than 620kPa, pressure switch is controlled the bright of pilot lamp, when air feed pressure drops to less than 550kPa (sluggishness of pressure switch is adjusted into 70kPa), going out of pressure switch control pilot lamp, pilot lamp is bright inconsistent during this and wes' controlled target---550kPa≤air feed pipe pressure≤620kPa, do not reach our monitoring requirement to two-tube air feed pressure, therefore two-tube air feed pilot lamp can not correctly be controlled, and easily the steward is misled.For this reason, two-tube air feed shows that control must the new control model of employing.As seen from the above analysis, the two-tube air feed of existing locomotive shows that the control mode of pilot lamp is unreasonable, can not realize correct demonstration control.Therefore, we must show that control improves design to two-tube air feed.
The utility model content
The purpose of this utility model is, at the two-tube air feed problem of air supply system in the existing electric locomotive, proposes a kind of two-tube air feed and shows the more rational device of control mode.The two-tube air feed of this device shows that controlling pilot lamp bright is consistent with controlled target pressure.
According to the technology implementation scheme that the purpose of this utility model proposed be: a kind of two-tube air feed display control unit, comprise that first air feed shows pilot lamp, second air feed shows pilot lamp and pressure transducer, between pressure transducer and two two-tube air feeds demonstration pilot lamp, be provided with the pressure display module of forming by single-chip microcomputer and signals collecting etc., two-tube air feed shows that pilot lamp is controlled by pressure display module, when 550kPa≤air feed pipe pressure≤620kPa, programmed control by pressure display module, output DC24V voltage signal, the I end is bright with II end air feed pilot lamp, the air feed pipe pressure is during less than 550kPa with greater than 620kPa, programmed control by pressure display module, pressure display module is exported 0 voltage signal, and the I end holds two-tube air feed to show that pilot lamp goes out with II.Realization shows the correct control of pilot lamp to two-tube air feed.
Principle of work of the present utility model is: pressure transducer detects air feed pipe pressure signal in real time and gives pressure display module, handles the light on and off that the two-tube air feed of controlling locomotive I end and II end afterwards shows pilot lamp through pressure display module.The two-tube air feed display control unit of novel locomotive is made up of pressure transducer and single-chip microcomputer and signals collecting etc., by the control of program, realizes that two-tube air feed shows the correct control of pilot lamp.The use of the two-tube air feed display control unit of novel locomotive, the two-tube air feed that further improves locomotive shows control, gives the steward with correct indication, for the safe operation of locomotive provides reliable assurance, has good economic and social benefits.
Description of drawings
Fig. 1 is the utility model structural principle synoptic diagram.
Among the figure: 1, I end wind shows pilot lamp; 2, II end air feed shows pilot lamp; 3, pressure display module; 4, pressure transducer.
Embodiment
Accompanying drawing has provided an embodiment of the present utility model.The utility model will be further described below in conjunction with drawings and Examples.
From accompanying drawing as can be seen, the utility model is the display control unit that a kind of two-tube air feed shows pilot lamp.Comprise that I end air feed shows pilot lamp 1, II end air feed shows pilot lamp 2 and pressure transducer 4, show that at pressure transducer 4 and I end air feed pilot lamp 1 and II hold air feed to show between the pilot lamp 2 and be provided with the pressure display module of being made up of single-chip microcomputer and signals collecting etc. 3, two-tube air feed shows that pilot lamp is controlled by pressure display module 3, when 550kPa≤air feed pipe pressure≤620kPa, programmed control by pressure display module, output DC24V voltage signal, I end air feed shows that pilot lamp 1 and II end air feed show that pilot lamp 2 is bright, the air feed pipe pressure is during less than 550kPa with greater than 620kPa, programmed control by pressure display module, pressure display module is exported 0 voltage signal, and I end air feed shows that pilot lamp 1 and II end air feed show that pilot lamp 2 goes out.Realization shows the correct control of pilot lamp to two-tube air feed.
Principle of work of the present utility model is: pressure transducer detects air feed pipe pressure signal in real time and gives pressure display module, handles the light on and off that the two-tube air feed of controlling locomotive I end air feed demonstration pilot lamp 1 and II end air feed demonstration pilot lamp 2 afterwards shows pilot lamp through pressure display module.The two-tube air feed display control unit of novel locomotive is made up of pressure transducer and single-chip microcomputer and signals collecting etc., by the control of program, realizes that two-tube air feed shows the correct control of pilot lamp.The use of the two-tube air feed display control unit of novel locomotive, the two-tube air feed that further improves locomotive shows control, gives the steward with correct indication, for the safe operation of locomotive provides reliable assurance, has good economic and social benefits.
