Wherein: 1-reflective photoelectric sensor, 2-pointer tensimeter.
Embodiment
Below in conjunction with specific embodiments and the drawings, further set forth the present invention.
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, the reflective photoelectric sensor array places the pointer instrument surface, and whether by the detection position, its mounting structure as shown in Figure 1 for detection of gauge hand.Reflective photoelectric sensor can be fixed in one and tensimeter surface configuration and disc of the same size, the corresponding position of detecting of disc has detects the hole, and integral body covered be fixed in the tensimeter surface, be used for reducing surround lighting to the disturbing effect of reflective photoelectric sensor.Signal processing module wherein, the situation of being blocked by pointer according to the reflective photoelectric sensor array with the corresponding numerical value segmentation digitized processing of its detection position, and transfers to communication and sound and light alarm module with result, is used for communication and sound and light alarm and indicates.Detailed process is as follows:
1. open the air respiratorresuscitator valve, gauge hand turns clockwise, and successively by the reflective photoelectric sensor array, is to stop during pressure position in the steel cylinder up to indicating value.
2. pointer turns clockwise, when blocking first reflective photoelectric sensor, level signal when signal processing module obtains blocking, and the record that is not blocked according to other reflective photoelectric sensor last time, judging at this moment, pointer is to turn clockwise, record the situation that this reflective photoelectric sensor is blocked clockwise, and will signal to communication and sound and light alarm module, light a LED and indicate current air surplus.
3. pointer continues to turn clockwise and blocks other reflective photoelectric sensor, signal processing module had the change records of blocking and the reflective photoelectric sensor that is in higher indicating value position that the record that is blocked is not arranged according to the reflective photoelectric sensor that is in lower indicating value position, judging pointer is to turn clockwise, record the situation that corresponding reflective photoelectric sensor is blocked clockwise, communication is indicated current air surplus with the LED that the sound and light alarm module is lighted corresponding number.When pointer blocks the highest indicating value position reflective photoelectric sensor, the situation that record most significant digit reflective photoelectric sensor is blocked clockwise, communication is lighted the LED of most significant digit with the sound and light alarm module, and the prompting air capacity of sounding is full.
4. indicate to the highest air surplus of air respiratorresuscitator certain hour when pointer is stable, communication sends radio signal with the sound and light alarm module to back court commander unit, indicates the current air surplus of this air respiratorresuscitator.
5. the fireman brings into use air respiratorresuscitator, and gauge hand is rotated counterclockwise owing to air is consumed to use by the fireman.
6. pointer is rotated counterclockwise, and when blocking corresponding reflective photoelectric sensor, the level signal when signal processing module obtains blocking records the situation (block for the second time and be counterclockwise process) 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, the record that is blocked by secondary according to this sensor, and be not blocked or the record that blocks counterclockwise arranged (if current location is last sensor according to being in the record that lower indicating value position reflective photoelectric sensor blocked clockwise and being in higher indicating value position reflective photoelectric sensor, then need not to consider higher indicating value situation), judge that this moment, pointer was rotated counterclockwise through current sensing station, so close the LED of correspondence position, the prompting of sounding, and send radio signal to back court commander unit.
According to fire-fighting actual combat demands of applications, the reflective photoelectric sensor array preferentially is installed in the position of specific demand, for example last reflective photoelectric sensor is placed in specified tolerance position, a reflective photoelectric sensor is placed in half position of specified tolerance, and low pressure alarming regional location (tensimeter red alarm zone) is placed a reflective photoelectric sensor.Can use simultaneously the LED difference indication of different colours, it is shown in green for example to reach specified tolerance; Half of being down to specified tolerance is shown as orange, and with rapid alarm sound prompting fireman should note this moment tolerance only surplus half, should in time return; When being down to last low pressure alarming zone, shown in red flicker, and point out the fireman promptly to return with more rapid alarm sound.
