Domestic present all kinds of pick-up units are a lot; But colliery refuge chamber (survival capsule) is at the early-stage basically with the internal environment pick-up unit, and its technology also only is to utilize above-mentioned detecting sensor that environmental parameter is detected on display screen to show, often exists fault discovery untimely; Find after the fault problems such as fault analysis are inaccurate; Detect poor effect, and inaccurate testing result just might cause bigger accident, threaten personnel's life security.
Summary of the invention
Be technical deficiency more than solving, the utility model provides a kind of detection accurate, can in time find fault based on environmental detection set in the colliery refuge chamber of fault self-diagnosis or the survival capsule.
The utility model is realized through following measure:
Environment measuring dress in the utility model a kind of colliery refuge chamber or survival capsule based on fault self-diagnosis
Put; Comprise the signal acquisition process device; The signal input part of said signal acquisition process device is connected with sensor, and the signal output part of signal acquisition process device is connected with and is used for intelligent trouble self diagnosis processor that the signal of gathering is carried out the Hilbert-Huang transform analysis.
Be record data, above-mentioned signal acquisition process device is connected with the SD storage card.

Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Embodiment
As shown in Figure 1, encircle in a kind of colliery refuge chamber or survival capsule based on fault self-diagnosis of the utility model
The border pick-up unit; Comprise the signal acquisition process device; The signal input part of signal acquisition process device is connected with sensor, and the signal output part of signal acquisition process device is connected with and is used for intelligent trouble self diagnosis processor that the signal of gathering is carried out the Hilbert-Huang transform analysis.Be record data, the signal acquisition process device is connected with the SD storage card.Sensor comprises methane transducer, carbon monoxide transducer, carbon dioxide sensor, oxygen concentration sensor, humidity sensor, temperature sensor and differential pressure pickup.The signal acquisition process device is connected with display and warning device.
Its principle of work is: system utilizes methane transducer, carbon monoxide transducer, carbon dioxide sensor, oxygen concentration sensor, humidity sensor, temperature sensor and differential pressure pickup to detect the interior environmental parameter in monitoring chamber (cabin); Adopting custom-designed signal acquisition process device to concentrate to each sensor parameters gathers, sends signal to intelligent trouble self diagnosis processor after the collection.Intelligent trouble self diagnosis processor carries out analyzing and processing to the signal of gathering, and is converted into the value of corresponding engineering meaning, utilizes signal Processing and fault self-diagnosis technology; Signal to gathering carries out the Hilbert-Huang conversion, and detailed process is: at first signal is carried out MED and decompose, and each rank eigenmodes function of data sequence is carried out the Hilbert conversion; Obtain instantaneous frequency; Utilize HHT to analyze then, in time find the fault of sensor, favourable guarantee is provided the reliability of installing.
Display partly adopts the Chinese character LCD with Presentation Function backlight of 640 * 480 resolution, is used to show each road sensor passage number, inserts sensor name, measured value etc.Passage order with numerical value 1～8 expression input quantity passage 1 to passage 8; Sensor name is represented with hanzi form, shows 4 Chinese characters at most; Numerical value shows and shows with 4-digit number.Adopt two chromatic liquid crystal screens (4 cun), show 3 sensor signal value on each display screen;
The SD storage card can write down the current measured value of each sensor automatically, whenever at a distance from 5 minutes records once.File layout is a text, user or read through any SD card reader;
Wrong when certain road sensor input signal, system points out this road sensor wiring error or operational failure automatically.When certain road measurement value sensor transfinites (upper limit or lower limit), system carries out the sound and light alarm prompting automatically; Irrelevance is big more, and alarm sound is rapid more, and light flash is quick more.The user can close sound, light warning function;
Transducer range can be set on control panel flexibly, therefore has extremely strong sensor adaptability; System allows each sensor settings value is automatically restored to the factory setting value.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
