The specific embodiment

As shown in Figure 1, this device is formed by the electric loop that each electronic devices and components in the circuit board are connected to form is installed, and electric loop comprises power circuit parallel with one another, condition indication circuit, amplifying circuit, time base circuit, delay circuit and control circuit; The pair of control lead-out wire of control circuit connects remote controller, and the lead-out wire of power circuit is connected on the current supply circuit of air-conditioning equipment; Wherein, power circuit by be connected power transformer T on the electric loop and three terminal regulator A1 and capacitor C 1, C2, C3, C4 forms; Wherein, condition indication circuit is made up of the VL1 that is connected in parallel on electric loop, R1; Wherein, amplifying circuit is made up of the transistor VT and peripheral cell R2, R3, C5, the VL2 that are connected in parallel on the electric loop; Wherein time base circuit is made up of the 555 time-base integrated circuit A2 and peripheral cell R4, C6, C7, the VD7 that are connected in parallel on the electric loop; Wherein, delay circuit is formed by being connected in parallel on elements such as R4, VD7 on the electric loop, C6; Wherein, control circuit is made up of the K1-K3 relay, VD5, VD6, the VD8 that are connected in parallel on the electric loop; Wherein, the operating state indication is made up of the R5, the VL3 element that are connected in parallel on the electric loop.

Air-conditioning incoming call automatic bus is when civil power arrives, power transformer T transformation in installing, output AC 15V voltage, bridge rectifier rectification, capacitor C 1, the C2 filtering of forming through D1-D4 again, become a DC voltage about 18V, offer three terminal regulator A1 and carry out voltage stabilizing, export a stable 12V DC voltage, for various circuit in installing provide working power; This moment the power supply status circuit working, indicator lamp VL1 lights; The A2 time base circuit is formed a monostable timing controlled mode of operation by NE555 integrated package and peripheral cell, and circuit gets electric work can produce a high level, the adhesive of K3 relay, its normally opened contact K3-b closure at circuit output end 3 pin; Because this contact is to connect air-conditioning remote control, thereby starts remote controller first in the incoming call very first time---" shutdown ", operating state indicator lamp VL3 lights; Through preset time t (t=1.1R ₂C ₆) after, A2 time base circuit 3 pin output low levels and remaining unchanged, this moment, operating state indicator lamp VL3 extinguished, the K3 relay electric-loss, contact K3-b disconnects, and it recovers its original contact normally open (as shown in Figure 2); Another route triode VT and peripheral cell are formed the time-delay amplification control circuit, because of C5 electric capacity both end voltage can not be suddenlyd change, behind incoming call, the device working power is charged to C5 through R2, through preset time t2 (after the process of t2 〉=2t1), triode VT conducting work, the adhesive of K1 relay; Since t1 after the time A2 time base circuit reset, this moment K1 relay normally open contact K1b closure, because K1 relay normally open contact K1b is connected 2 pin of A2 time base circuit, principle according to monostable timing controlled mode of operation, this moment, the K1b closure made the charge discharging resisting that stores on the capacitor C 6, the high level of 2 pin output simultaneously, trigger the A2 time base circuit so once more, circuit output end 3 pin produce a high level again, operating state indicator lamp VL3 lights once more, it controls the adhesive of K3 relay, and the air-conditioning remote control that makes the K3b contact be connect starts for the second time---and " start " formally starts the machine room air-conditioning equipment; Meanwhile another is to K1 relay normally open contact K1a closure, and the K2 relay gets electric adhesive, and its normally opened contact K2b closure is finished the self-locking of K2 relay; Because the K2 relay gets electric adhesive, make the normally-closed contact K2a that connects the K1 relay disconnect, the K1 relay is dead electricity thereupon, and 2 pin of A2 time base circuit connect the K1b contact and disconnect, and finish this moment and trigger the A2 time base circuit and recover the original normally open task in its contact; So far, the A2 time base circuit regularly promptly begins, and positive supply charges to C6 by timing resistor R4, make the C6 both end voltage promptly the threshold values 6 pin level of 555 time base circuit A2 constantly raise, when being raised to 2V _DD/ 3 o'clock, time base circuit A2 resetted, and regularly finished, and 3 pin recover output low level, and K3 relay electric-loss, K3b disconnect and recover its reset condition (as shown in Figure 3); So far, air-conditioning incoming call automatic bus has been finished whole courses of work.
