Embodiment
Referring to figs. 1 through Fig. 3, the self-monitoring switch cubicle embodiment of the utility model levelness is described further.
As shown in Figure 1, the self-monitoring switch cubicle of a kind of levelness, comprise cabinet 1, described cabinet 1 is provided with the level detection device 2 for detecting cabinet 1 levelness, described level detection device 2 is provided with warning circuit, and described warning circuit is sounding alarm when cabinet 1 tilts.Level detection device 2 is by being fixedly welded on the top of cabinet 1.Described level detection device 2 comprises housing 21, level trough 22 and ball 23, the vertical section of level trough 22 is T-shaped, ball 23 is Free-rolling in level trough 22, level trough 22 is arranged in housing 21, sidewall is the motion conditions that transparent material can observe ball 23, described housing 21 and cabinet 1 also can be screwed and be connected (not shown), and described ball 23 rolls in level trough 22.When cabinet 1 places level time, ball 23 is motionless, can move ball 23 to centre position by finger one, but if cabinet 1 tilts, ball 23 certainly will roll to lower, arrives one end of housing 21.All warning circuit is provided with at the two ends of housing 21.
Warning circuit comprises detecting unit, logic gate 33, driver element and buzzer 34; Described detecting unit is coupled to logic gate 33 for detecting ball 23 position and output detection signal; Described logic gate 33 is coupled to driver element in order to receive detection signal and output drive signal; Described driver element is coupled to buzzer 34 and reports to the police in order to receive drive singal and to trigger buzzer 34.
Detecting unit comprises the first test section and the second test section, and described first test section and the second test section are arranged at housing 21 two ends respectively.First test section comprises the first Light-Emitting Diode and the first phototriode 32, and described ball 23 can block the first light-emitting diode 31 and the first phototriode 32; Described first Light-Emitting Diode is in order to emission of light; Described first photosensitive triode is coupled to logic gate 33 in order to receive the first Light-Emitting Diode and to export the first detection signal.
Second test section comprises the second Light-Emitting Diode LED2 and the second phototriode VT2, and described ball 23 can block the second LED 2 and the second phototriode VT2; Described second Light-Emitting Diode LED2 is in order to emission of light; Described second photosensitive triode VT2 is coupled to logic gate 33 in order to receive the second Light-Emitting Diode LED2 and to export the second detection signal.First test section is substantially identical with the second test section circuit structure.
Logic gate 33 is OR circuit, export and be connected with the grid of NMOS tube, the source ground of NMOS tube, the drain electrode of NMOS tube is connected with resistance R7, drain electrode is also connected with buzzer 34 one end, buzzer 34 other end is connected with resistance R8, and be connected with Light-Emitting Diode LED5 between resistance R8 and R7, resistance R8 connects power supply simultaneously.
As shown in Figure 3, the first detection signal or the second detection signal are by realizing after logic gate 33 reporting to the police, and described logic gate 33 is connected to receive detection signal with buzzer 34 and exports control signal; Described buzzer 34 responsive control signal is also reported to the police.LED 1 emits beam, phototriode receives light and conducting, input pin that is in logic gate 33 or door is made to be low level, when ball 23 moves to housing 21 end, shelter from the light of Light-Emitting Diode LED1, phototriode is ended, input pin that is so in logic gate 33 or door is high level, the other end of housing 21 is provided with same circuit, as long as there is the phototriode of one end not receive light, so logic gate 33 or door just export high level, make NMOS tube conducting, thus make buzzer 34 sounding alarm and LED5 luminescence, illustrate because cabinet 1 tilts to make ball 23 block LED1 or LED2, thus sounding alarm.
Warning circuit is also provided with indicator unit, described indicator unit is in parallel with buzzer 34 to be indicated in order to simultaneously luminous, the direction that cabinet 1 tilts is judged in order to what can make that installation personnel can be convenient, circuit diagram in Fig. 3 connects LED3 and LED4, the glow color of LED3 and LED4 is different, for convenience of explanation, red LED 3 and green LED 4 is adopted in present embodiment, then illustrate that the position of housing 21LED1 end is too low when red LED3 is bright, if green light LED4 is bright, illustrate that LED2 end is too low.Installation personnel can be made by light thus can be judged the direction of inclination, and making detection and install can be very convenient.
