After now general unit establishes summary table or finishing, air switch or do not establish, or be located in the office, and substantially no longer assemble air switch on the corridor.If consider energy-conservation and patrol and examine the needs of control, described as this patent, install controlled distribution box in the appropriate location that does not affect the appearance and be necessary.Certainly, if floor still has distribution box, also need transform, adding can be surveyed curved line, controlled individual switch, acousto-optic and control piece etc., can use.
Circuit has several characteristics to need additional description:
1, storage battery energy conservation:
The basic load of this distribution box is acousto-optical device, and energy consumption is minimum, and as if the transformation that adopts alternating current, rectification, voltage stabilizing etc., its electromagnetic conversion and heat energy consumption have been far longer than it, so at ordinary times mainly by battery-operated.Simultaneously, if occur that sound is little, a little less than the photoelectricity, show that electric weight reduces, phenomenon is obvious, so this circuit is not established sampling, comparison, decision circuitry, further reduces branch's power consumption, prolongs storage battery service time.Under the short of electricity situation, just plug is inserted the 220V socket in this casing, both can transfer AC and DC to and work simultaneously, charge again, when power supply is full of, pull out plug again, recover storage battery and work alone.In service day by day, saves energy greatly is so be an ingenious and distinctive design.
2, multiple tube on-off action:
Multiple tube BG1, BG2 are by S8050 and 3DG12, and the power amplifier of formation can carry hundreds of milliamperes current value, and single electric current of sound equipment and light-emitting diode is about 20 milliamperes, and several problems in parallel are also little.So this circuit is no longer established the relay conversion, but directly multiple tube is used as switch.Multiple tube ends at ordinary times, arrives when the time that arranges, and clock chip 1 pin output high level makes it conducting, sends the positive supply of collector electrode to oscillator work, as seen, plays on-off action really.
3, oscillator unbalanced operations:
General multivibrator electric parameter is balance, but our Fig. 4 acousto-optic warning circuit left and right sides structure of design is different, parameter is obviously uneven, especially the single face setting of potentiometer W, more aggravated unbalanced deal, this is because our sound equipment and photoelectricity flicker main points on the left side, consider that the retention time should be more longer, so need not the both sides balance, and have a mind to be set to the adjustable circuit of pulse duration.The realization of this function also is that we are to the ingenious application of the oscillator fundamental characteristics of monostable flipflop formation.
Occupation mode: after energy-saving distribution box and the circuit installation thereof, just can come into operation.At first, the hand-holdable electric current of electrician divides the DT9258 pincerlike meter of 2 ~ 600A fourth gear to patrol and examine measurement, detect No. 4 and No. 17 offices have 0.8A respectively and more than the 3A electric current herein, do not have message form again, namely judge it is that this clerk forgets the pass power supply, then dialling down earlier, on ﹠ off switch makes it outage, again acousto-optic is arranged on 8:00---9:00 start-up time, and press K4 and K17 branch switch, when the time arrives, controller will send the acousto-optic warning signal.Ask for an interview Fig. 5:
Fig. 5 is distribution box top view figure, and when hearing acoustic signal, the deskman can see that the light of No. 4 and No. 17 is in flicker from observation window, on ﹠ off switch is dialled down simultaneously, and then the personnel of this two office should reflect on oneself, simultaneously, can call contact, the electrician can come very soon, for it opens distribution box, close a switch, restore electricity, disconnect K4, K17 switch simultaneously, may be less than at 9 o'clock this moment, but because of line interruption, so sound equipment and light caution effect are also removed thereupon.
Also have what time need additionally introduce and be:
1, from Fig. 3, Fig. 5 as seen, this distribution box switch member is divided the two rows setting, amounts to 20 assembled arrangement, compact and reasonable, and according to floor and the office of controlling how much, also can regulate increase and decrease, convenient, flexible;
2, the effect of this case of message box structure is that the clerk sends to information to the electrician, closes power supply with fault-avoidance.Its structure as shown in Figure 6, in order to guarantee the locational space of inner circular camber line, casing is pressed narrowly, as Fig. 6 a, delivery port is only to be the cylindrical void of a 6 * 2cm, can only put into little paper slip and maybe will use the folding back of A4 paper always and drop into; Fig. 6 b is the end view of 3 * 15cm height anyhow in the door, and the top breakpoint is represented delivery port; Fig. 6 c is the casing (backsight) of 6 * 2 * 15cm, can also see an arc notch from this figure, and this is to be convenient to point fetch the set aperture position of message form;
3, patrol record table
For the office of forgetting to close power supply, the particularly criminal of length, recidivist, should strengthen management, we have formulated following patrol record table for this reason:
This table has patrols and examines the year, month, day of pinpointing the problems, and several, which floor, which office and time of power cutoff when are arranged, and the more important thing is that being stopped the clerk must note down in signature, can restore electricity.Like this, the one, the staff is played warning function, simultaneously, according to record, also can be used as examination, evaluate, add the foundation of deduction of points.
Therefore this project is patrolled and examined, measures, pinpoints the problems, is recorded, restores electricity for pass power supply, acousto-optic warning, statistical form, is an integral framework, and the realization of this system has not only produced energy-conserving action, has also effectively improved coefficient of safety.
