Embodiment

In order better to understand the technical solution of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.

The utility model has utilized a kind of bus communication and control technology based on controllable AC pulse power supply power supply to set up the collective and distributive type bus control system.As shown in Figure 1, this system has comprised at least one master controller, some bus controller and the assembly of some normally closed type mechanical switchs and commutation diode.This master controller provides the control bus of at least one group of controllable AC pulse power supply power supply, described control bus is the nonpolarity buses of two lines, both can provide working power for the bus controller on the control bus, also can be used as switch with mechanical contact on described bus controller and the control bus and the assembly of commutation diode, and set up the pulse signal source of communication between the master controller.Simultaneously, described master controller is by the formed control information of alternating-current pulse curent change on the current detecting comparator circuit acquisition control bus of its bus port, and the CPU of master controller implements control to the state of corresponding control output end mouth respectively according to these different control informations.

Master controller CPU forms as shown in Figure 2 various half-wave pulse combined information by AC pulse power supply being exported the mode of control, realizes communication and control to bus controller.

Form the bus control loop between bus controller and the master controller, when the pulse signal source that control bus is provided when bus controller is implemented the Bypass Control of half-wave pulse, make the combination current generation variation as shown in Figure 3 of the half-wave pulse forward or backwards on the control bus, detection comparator circuit through described main control system obtains its control information again, then, master controller CPU is again according to the control of control information Content Implementation to the output state of its corresponding port.

Preferably, also comprise: on described control bus, can adopt switch with mechanical contact open in usual to carry out point-to-point control.With described switch with mechanical contact open in usual or itself and commutation diode, access respectively bus and form different control bus loops from master controller.When these switch with mechanical contact open in usual moment closures, the forward half-wave of the alternating-current pulse signal of control bus, negative sense half-wave or all-wave train of impulses are by switch with mechanical contact bypass open in usual, at this moment, the electric current of forward half-wave, negative sense half-wave or all-wave train of impulses on the control bus is changed, thus communication and control between realization and the master controller.Each group control bus can access respectively the differential concatenation assembly of forward tandem compound body, itself and the commutation diode of a switch with mechanical contact open in usual, itself and commutation diode, namely form forward half-wave, negative sense half-wave or three kinds of control informations of all-wave train of impulses, because the port of every group of control bus is not identical, therefore, three groups of switch with mechanical contacts open in usual between control bus and be separate with assembly after commutation diode is connected.

A kind of hotel guest room lamp light control system of setting up based on bus communication and the control technology of controllable AC pulse power supply power supply that the utility model Application Example provides.

In this application embodiment, hotel guest room controller as shown in Figure 7 namely is master controller described in the utility model, and what control at the output port of hotel guest room controller is lighting, comprises lamp 1, lamp 2, lamp 3 and lamp m; Simultaneously, counted respectively at bus 1 and bus n and to be described as " plug-in card power taking " and " sleeping/get up in the night to urinate " bus controller, also accessed and be described as " lamp 1 switch ", " lamp 2 switches ", " lamp 3 switches " and the switch with mechanical contact of " lamp m switch " and the various combination body of commutation diode.

In this application embodiment, " plug-in card power taking " bus controller and " sleeping/get up in the night to urinate " bus controller can be controlled the various combination state that all light fixtures are exported.For example, after " plug-in card power taking " bus controller plug-in card starts, send the control information of one group of alternation pulse current combination by bus 1 to the hotel guest room controller, and control respectively " the welcome scene " that the particular switch state of lamp 1, lamp 2, lamp 3 and lamp m makes up by corresponding one group of the CPU output of hotel guest room controller.Same, the control information of another group alternation pulse current combination the when bus controller of " sleeping/get up in the night to urinate " also can send for " sleep " or " getting up in the night to urinate " by control bus n, and the particular switch state of controlling respectively lamp 1, lamp 2, lamp 3 and lamp m by another group corresponding to the CPU output of hotel guest room controller " the sleep scene " or " scene of getting up in the night to urinate " that make up.

In this application embodiment, preferably, the switch with mechanical contact of lamp 1 switch, lamp 2 switches, lamp 3 switches and lamp m switch and the various combination body of commutation diode, can distinguish directly control corresponding the on off state of lamp 1, lamp 2, lamp 3 and lamp m, or the dimming state of lamp m.When lamp 1 switch, lamp 2 switches and lamp 3 switch triggering, the commutation diode of its serial connection has sent one group such as the control information of Fig. 4, Fig. 5 and forward half-wave pulse, negative sense half pulsating wave or overall pulse crosstalk stream shown in Figure 6 by bus 1 to the hotel guest room controller respectively, and the on off state that the CPU by the hotel guest room controller exports respectively corresponding lamp 1, lamp 2 and lamp 3 is implemented upset control.During for lamp m switch triggering, although what send on bus with lamp 1 switch all is as shown in Figure 4 forward half-wave pulse crosstalk stream, but, because its place bus n and bus 1 are independently ports of difference, therefore, the CPU of hotel guest room controller will be as independently exporting the upset control of implementing lamp m on off state.

Above a kind of information source formula collective and distributive type pulse bus control system that the utility model embodiment is provided is described in detail, for one of ordinary skill in the art, thought according to the utility model embodiment, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
