Abstract
The utility model discloses a warning lamp box. The warning lamp box comprises a processor unit. The warning lamp box is characterized in that an input end of the processor unit is connected with a discrete acquisition unit, another input end of the processor unit is further connected with two path bus interfaces, and an output end of the processor unit is connected with a warning display unit through a light driving unit. The warning lamp box solves problems of difficulty and defectiveness existing in circuit design of a warning lamp box in the prior art from aspects of high integration level, transmission rate and transmission redundancy.
Description
Technical field
The utility model belongs to electronic circuit design field, is specially a kind of stand by lamp box of the corresponding alarm viewing area for all kinds of aircraft cabin domestic and foreign works zone.
Background technology
The stand by lamp box is mainly used in the corresponding alarm viewing area in all kinds of aircraft cabin domestic and foreign works zone and since at present product towards integrated trend development, the various data messages between product by bus transfer also become aircraft of new generation require required.But stand by lamp box data message then adopted the discrete magnitude form to carry out in the past, and like this, product has brought very big heavy burden to aircraft, and brought very big burden past aspect the product bug investigation to the maintenance personal.
The utility model content
The utility model provides the stand by lamp box of the high integration of a kind of pair of remaining bus design.
To achieve these goals, the technical solution of the utility model is as follows: a kind of stand by lamp box, comprise processor unit, an input end that it is characterized in that this processor unit is connected with the discrete acquisitions unit, another input end of this processor unit also is connected with the two-way bus interface, and the output terminal of this processor unit is connected with the alarm display unit by the light driver element.According to specific embodiment of the utility model, the input end of described processor unit is connected with self-test unit by the discrete acquisitions unit, and the input end of described processor unit is connected with front-end computer with the two-way bus interface.Described bus interface is the RS422 bus interface, and described processor unit is the C8051F020 single-chip microcomputer.This alarm display unit also is connected with light adjusting circuit with power supply.
The processor unit of this utility model passes through the bus alarm signal of receiving front-end computing machine, and this signal is carried out logic judge, the result after the analyzing and processing is shown by the alarm display unit.This stand by lamp box is to be support with the C8051F020 single-chip microcomputer, utilizes features such as two-way RS-422 bus transfer warning information, can satisfy aircraft stand by lamp box of new generation designing requirement, to reach the purpose of the information of transmitting with bus.The utility model has solved difficulty and defective that the stand by lamp box exists aspect circuit design aspect high integration, transfer rate and transmitting redundancy degree.
Description of drawings
Fig. 1 is circuit block diagram of the present utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
A kind of stand by lamp box, comprise processor unit, an input end that it is characterized in that this processor unit is connected with the discrete acquisitions unit, another input end of this processor unit also is connected with the two-way bus interface, the output terminal of this processor unit is connected with the alarm display unit by the light driver element, when the two-way bus was all effective, processor carries out logical OR to be handled, and the result after handling is being exported to the light driver element; When one road bus failure wherein, automatically switch to other one tunnel bus and communicate, the warning information after will judging is again exported to the light driver element.According to specific embodiment of the utility model, the input end of described processor unit is connected with self-test unit by the discrete acquisitions unit, and the input end of described processor unit is connected with front-end computer by the two-way bus interface simultaneously.Described bus interface is the RS422 bus interface, and described processor unit is the C8051F020 single-chip microcomputer.This alarm display unit also is connected with light adjusting circuit with power supply.Described light adjusting circuit and self-test unit are prior art, do not repeat them here.
The utility model carries out communication according to the communication protocol that pre-defines and front-end computer, front-end computer utilizes two-way RS422 bus signals simultaneously warning information to be passed to this stand by lamp box, bus message is passed to processor unit, processor unit is with the RS422 bus message code that receives simultaneously, when the two-way bus is all effective, processor carries out logical OR to be handled, and the result after handling is being exported to the light driver element; When one road RS422 bus failure, automatically switch to other one tunnel bus and communicate the input end signal that warning information output useful signal after will judging more at last is used as the light driver element, alarm display unit and under the drives of light driver element, obtained the driving signal.
The utility model carries out the satisfied day and night two states of Current limited Control by the light adjusting circuit of alarm display unit, and the detected inspection modulating signal of self-test unit enters the alarm indicative control unit at last by the discrete acquisitions unit, to realize the circuit self-checking function.Brightness transition signal at day/night can be accepted in described light modulation unit, and dim signal satisfies product different brightness demand when two states day and night.
The utlity model has in light weight, RS422 bus remaining, self check, functional characteristics such as with an automatic light meter.
The utility model is mainly used in the interior stand by lamp box with bus transfer warning information such as RS-422, RS-232 of aircraft.The utility model also can be used for using with bus forms such as RS-422, RS-232 transmission data and with the design of stand by lamp or display screen demonstration corresponding information in all kinds of aircrafts, the automobile.
