The utility model compared with prior art has the following advantages:
1, can effectively detect the signal line of autogyro;
2, alleviated weight and volume;
3, improved the speed of response of system.
Description of drawings
Fig. 1 is the system chart of a kind of autogyro failure warning system of the utility model;
Fig. 2 is the detecting device of a kind of autogyro failure warning system of the utility model and the block diagram that is connected of processing equipment.
The specific embodiment
Below in conjunction with accompanying drawing,, the utility model is done further elaboration through specifying a preferable specific embodiment.
As shown in Figure 1, a kind of autogyro failure warning system comprises: processing equipment 1, read out instrument 2, detecting device 3; Read out instrument 2 links to each other with processing equipment 1 through circuit, and detecting device 3 links to each other with processing equipment 1 through data bus.Wherein, also be provided with stable-pressure device 4 between the power supply of the power supply of processing equipment 1 and detecting device 3.
In the present embodiment, stable-pressure device 4 is selected the DC-DC changer for use, guarantees that the power supply of processing equipment 1 and detecting device 3 is isolated, thereby guarantees that the various of the external world can not exert an influence to processing equipment 1 unusually; Read out instrument 2 is selected Organic Light Emitting Diode (OLED) read-out for use; With respect to general LCDs; In light weight, advantages such as brightness is high, thin thickness that the OLED read-out has are adapted at that autogyro is this to be required than higher occasion weight, brightness, volume etc.; Processing equipment 1 is selected embedded-type ARM 11 treater S3C6410 CPU for use, and the work dominant frequency reaches 800MHz, satisfies system to the requirement in reaction time, has improved the speed of response of system greatly.
As shown in Figure 2, detecting device 3 also comprises: controller 31, analog signal device 32, comparator 33, digital signal device 34; Controller 31 links to each other with processing equipment 1 through data bus; Analog signal device 32 links to each other with controller 31 through circuit; Comparator 33 links to each other with processing equipment 1 and analog signal device 32 through data bus respectively; Digital signal device 34 links to each other with controller 31 through circuit, and this digital signal device 34 links to each other with processing equipment 1 through data bus.
In the present embodiment, controller 31 is for selecting complex programmable logic controller (CPLD) for use; Digital signal device 34 is selected optic coupler for use, and optic coupler links to each other with two cooresponding digital signal pins of CPLD, 2 way word signals of input autogyro; Analog signal device 32 is selected 6 analog switch plates for use, constitutes 92 tunnel analog inputs of autogyro, and these 6 analog switch plates are connected on 92 analog signal pins of CPLD.
When using, the pin of S3C6410 cpu command CPLD is a high level, and S3C6410 CPU detects totally 94 passages, if also be high, explains normal; The pin of S3C6410 cpu command CPLD is a low level, and S3C6410 CPU detects 94 passages, if also be low, explains normal.When aforementioned two detections are all normal, just whole 94 passages of detecting of illustrative are out of question; After detection finished, the pin of S3C6410 cpu command CPLD returned to normal, and makes autogyro withdraw from detected state, thereby made the CPLD of detecting device 3 not produce interference to the normal operation of autogyro.
In sum, a kind of autogyro failure warning system of the utility model can effectively detect the signal line of autogyro, has also alleviated weight and volume, and has improved the speed of response of system, has promoted the safety of autogyro greatly.
Although the content of the utility model has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to the restriction to the utility model.After those skilled in the art have read foregoing, for the multiple modification of the utility model with to substitute all will be conspicuous.Therefore, the protection domain of the utility model should be limited appended claim.
