Now the technology of the present invention solution is described below:
The invention provides a kind of small status monitoring record and fault diagnosis warning device, it is characterized in that: adopt serial communication technology to carry out record to the critical data that instrument runs, MOSI, SCK, MISO of RAM (random access memory) card memory module and SD CS port are connected respectively 11,13,12 and 4 ports of single-chip microcomputer, record is carried out to the data of single-chip microcomputer collection, when breaking down, recorded data is analyzed, promptly and accurately localizing faults.
The present invention further provides a kind of small status monitoring record and fault diagnosis warning device, it is characterized in that: the LED being used for reporting to the police is connected with the I/O mouth of single-chip microcomputer with hummer, when the normal data that single-chip microcomputer collects the data of monitoring point and storage inside is inconsistent, corresponding I/O mouth exports high level, lightening LED lamp, drives hummer to realize warning function, when system discovery abnormal data, report to the police, remind operating personnel to fix a breakdown in time in time.
The present invention further provides a kind of small status monitoring record and fault diagnosis warning device, it is characterized in that: adopt serial communication technology, the E of LCDs LCD12864,
with
namely 6,5,4 ports receive 3,8 and 9 mouthfuls of single-chip microcomputer respectively.When the data of monitoring point that single-chip microcomputer collects and internal data inconsistent time, just the program that a section drives display screen can be exported, LCDs is made to show the monitoring point of abnormal data and concrete abnormal conditions, when system discovery abnormal data, which kind of exception display module specifically can produce and which monitoring point abnormal data occurs in by display device.
The present invention compared with the existing technology, has that volume is little, impact resistance is strong, can online programming, and after single-chip microcomputer power down, data such as not to lose at the advantage.Proved by model rocket emission test, the correctness of its recorded data and stability meet the needs of aircraft.Prove by carrying out ground test, the data of its record are correct, stable, and note abnormalities in time, accurate positioning, satisfies the demand simultaneously.

Embodiment
Now by reference to the accompanying drawings the specific embodiment of the invention is further described below:
The single-chip microcomputer that the control that the present invention relates to and data acquisition system (DAS) adopt is ATMEAG328P, and inside is integrated with data acquisition module, can realize the acquisition function of data easily.And the record of data only need call the memory bank file of single-chip microcomputer, just can realize easily carrying out file read-write in RAM (random access memory) card, the data be stored in RAM (random access memory) card can also be read in computer carries out data processing.
Can compare with normal data while single-chip microcomputer image data, when note abnormalities data time, drive alarm module to report to the police, drive the display screen display monitoring point at abnormal data place and concrete abnormal conditions simultaneously.
The RAM (random access memory) card memory module that the present invention relates to, its embodiment is as follows: what this module adopted is that RAM (random access memory) card read-write memory module (Arduino SD Card v2.0) adopts easily inserted Design of serial communication interface based, and MOSI, SCK, MISO and the SD CS port of module are connected 11,13,12 and 4 ports of single-chip microcomputer respectively.Module board mounted power pilot lamp, can Real Time Observation power supply supply situation.Can realize the non-volatile recording to device data and storage, convenient after breaking down, promptly and accurately fault point getting rid of, its memory module principle is shown in Fig. 2.
