Embodiment
Below in conjunction with specific embodiments and the drawings, set forth the present invention further.
With reference to Fig. 2, the present invention is made up of reflective photoelectric sensor array, signal processing module, communication and sound and light alarm module.Wherein, reflective photoelectric sensor array is placed in pointer instrument surface, and whether for detected pressures list index by detecting position, its mounting structure as shown in Figure 1.Reflective photoelectric sensor can be fixed on one and pressure gage surface shape and disc of the same size, the position that disc correspondence detects has detect aperture, and entirety covering is fixed on pressure gage surface, for reducing the disturbing effect of surround lighting to reflective photoelectric sensor.Signal processing module wherein, according to the situation that reflective photoelectric sensor array is blocked by pointer, is detected the corresponding numerical value segmentation digitized processing of position, and result is transferred to communication and sound and light alarm module, for communication and sound and light alarm instruction.Detailed process is as follows:
1. open air respiratorresuscitator valve, gauge hand turns clockwise, successively by reflective photoelectric sensor array, until stop when indicating value is pressure position in steel cylinder.
2. pointer turns clockwise, when blocking first reflective photoelectric sensor, signal processing module obtains level signal when blocking, and according to the last record be not blocked of other reflective photoelectric sensor, judge that now pointer turns clockwise, record this reflective photoelectric sensor by the situation of blocking clockwise, and communication and sound and light alarm module will be signaled to, light a LED and indicate present air surplus.
3. pointer continues to turn clockwise and blocks other reflective photoelectric sensor, signal processing module had the reflective photoelectric sensor blocking change records and be in higher indicating value position not have the record be blocked according to the reflective photoelectric sensor being in lower indicating value position, judge that pointer turns clockwise, record corresponding reflective photoelectric sensor by the situation of blocking clockwise, the LED that communication and sound and light alarm module light corresponding number indicates present air surplus.When pointer blocks the highest indicating value position reflective photoelectric sensor, record most significant digit reflective photoelectric sensor is by the situation of blocking clockwise, and communication and sound and light alarm module light the LED of most significant digit, and prompting air capacity of sounding is full.
4., when the stable instruction of pointer is to air respiratorresuscitator the highest air surplus certain hour, communication and sound and light alarm module command unit to send radio signal to back court, indicate the present air surplus of this air respiratorresuscitator.
5. fireman brings into use air respiratorresuscitator, and gauge hand is rotated counterclockwise because air is consumed use by fireman.
6. pointer is rotated counterclockwise, and when blocking corresponding reflective photoelectric sensor, signal processing module obtains level signal when blocking, and records the situation (second time is blocked as process of anticlockwise) that this position reflective photoelectric sensor is blocked by secondary.
7. pointer continues to be rotated counterclockwise, leave this occlusion detection position, the level signal that signal processing module is not blocked, according to the record that this sensor is blocked by secondary, and according to being in lower indicating value position reflective photoelectric sensor by the record that blocked clockwise and be in higher indicating value position reflective photoelectric sensor and be not blocked or had the record blocked counterclockwise (if current location is last sensor, then without the need to considering higher indicating value situation), judge that now pointer is rotated counterclockwise and have passed through current sensor position, therefore close the LED of correspondence position, to sound prompting, and send radio signal to back court commander unit.
According to the demand of fire-fighting application in actual combat, reflective photoelectric sensor array is preferentially arranged on the position of specific demand, such as last reflective photoelectric sensor is placed in specified tolerance position, a reflective photoelectric sensor is placed in specified tolerance half position, and low pressure alarming regional location (tensimeter red alarm region) places a reflective photoelectric sensor.The LED region of different colours can be used not indicate simultaneously, such as, reach specified tolerance shown in green; The half of being down to specified tolerance is shown as orange, and should note now tolerance only surplus half with rapid alarm sound prompting fireman, should return in time; When being down to last low pressure alarming region, shown in red flicker, and should promptly return with more rapid alarm sound prompting fireman.
