Detailed description of the invention
It is described in detail below with reference to accompanying drawing each embodiment of this disclosure.One or more examples of embodiment are by shown by accompanying drawing.Embodiment is provided by the elaboration of the disclosure, and is not intended as restriction of this disclosure.Such as, yet a further embodiment may be used to generate in another embodiment as the feature shown or described by a part for an embodiment.The disclosure is intended to include belonging to these and other modifications and variations of disclosure scope and spirit.
Fig. 2 shows the DALI telecommunication circuit according to a basic embodiment of the present utility model, and wherein part of module is similar with DALI telecommunication circuit of the prior art, it may for example comprise:
-sensor power power supply, has voltage input and the voltage output being different from DALI bus, and the output of described voltage is couple to described DALI bus, for powering with the sensor device connected in described DALI bus to described DALI bus supply voltage；
-DALI receiver, is couple to described DALI bus, for detecting the DALI input signal of transmission in described DALI bus；
-DALI transmitter, is couple to described DALI bus, for DALI output signal being sent on the bus.
With existing DALI telecommunication circuit main difference is that described sensor power supply coupling to and supply electricity to described DALI receiver and described DALI transmitter, such as in Fig. 2 by sensor power power supply provide VauxPower supply signal is to DALI receiver and DALI transmitter.
To provide power supply to DALI Receiver And Transmitter by sensor power power supply, save extra, from DALI bus the accessory power supply of power taking, therefore reduce the size of DALI telecommunication circuit.Further, the restriction of maximum 2 milliamperes (mA) from DALI bus power taking also it is no longer limited by.
Another advantage is, powers owing to being no longer necessary to DALI receiver, so DALI receiver can be no longer current source formula, and can be voltage detection type (high input impedance).This also simplifies the design of receiver, be particularly electrically connected in city in the application of DALI bus.
In fig. 2, the control signal that whether control sensor power power supply works can pass through optocoupler from external transmission to sensor power power supply.
Fig. 3 shows an alternative embodiment, and the control signal that wherein whether control sensor power power supply works can control by releasing the voltage swing sensed on energy coil, and this generally can be controlled by input power.Such as when service voltage is higher, releasing the voltage sensed on energy coil also can be the highest.In this embodiment, sensor power power supply includes a voltage threshold circuit, according to induced voltage, this voltage threshold circuit controls whether sensor power power supply works.
Fig. 4 shows another alternative embodiment, wherein sensor power power supply for according to release can on coil the voltage of sensing to provide in DALI bus amplitude is different but electric current that polarity is identical.
Fig. 5 shows the circuit diagram according to the embodiment shown in Fig. 4.Fig. 6 shows the circuit diagram of the sensor power power supply in the DALI telecommunication circuit in Fig. 5.
In Figure 5, important improvement can embody from the upper right corner, wherein, releases the voltage V that energy coil is provided after rectification and filteringsuppAs being supplied to DALI receiver and the electric power of DALI transmitter.Alternatively, this voltage VsuppAgain pass by rectification and filtering, produce voltage VauxIt is supplied to DALI receiver and DALI transmitter.
As shown in Figure 5 and Figure 6, sensor power power supply have one release can coil, described in release that to sense the voltage of generation on coil be that described sensor power power supply provides input, specifically, release can coil after one group of rectifying and wave-filtering parts, produce voltage VsuppIt is connected to the positive pole DALI+ (or DA+) of DALI bus, and releases energy coil referring also to current potential ground.Sensor power power supply also includes a switch, the such as metal-oxide-semiconductor in figure, and this metal-oxide-semiconductor is connected to negative pole DALI-(or DA-) and the reference potential ground of DALI bus.In this case, it is disconnected completely by controlling this switch, then releasing of sensor power power supply can will not be in being formed in DALI bus loop by coil, and therefore sensor power power supply does not works.And when determining the output of described sensor power power supply, described switch can turn on, so that the energy released on energy coil is transferred in DALI bus.
For reasons of isolation, the energy releasing energy coil is to be produced by electromagnetic induction, and it can be the secondary of an inductive type energy transmission/conversion equipment, the e.g. secondary of a transformator, or the secondary of a flyback current transformer.The energy on former limit it is supplied to by change, just can change and release the energy sensing generation on energy coil, and change the output voltage releasing energy coil, with reference to described above, this output voltage can carry out detecting and control opening and closing of MOS switch through overvoltage threshold circuit.Such as when the voltage that the induced voltage released on energy coil is formed on the grid of MOS switch is less than the turning-on voltage of MOS switch, MOS switch will not turn on.
When the constant closedown of MOS switch, sensor power power supply is closed.When MOS switch controllably turns on, as shown in Figure 5 and Figure 6, the effect of sensor power power supply is to ensure that in DALI bus that having enough power is provided to sensor device.In the embodiment of Fig. 5 and Fig. 6, MOS switch is controlled have variableimpedance according to voltage/current in described DALI bus, provides the electric current in described DALI bus controlling described sensor power power supply.Concrete, the source electrode at MOS switch connects detection resistance Rsense, this detection resistance flows through the electric current of detection resistance for detection, produces voltage on detection resistance, and this voltage is relevant to the voltage of the both positive and negative polarity in DALI bus.This detection resistance is connected to the controllable silicon as current threshold detecting element.When detecting, ohmically voltage is sufficiently high, indicate existing enough electric currents (now DALI positive pole should be to be shorted to DALI negative pole) in DALI bus, controllable silicon is excited and turns on and dragged down by the grid voltage of MOS switch, thus reduces the power being supplied to DALI bus by sensor power network.On the contrary, when detecting, ohmically voltage is relatively low, indicate in DALI bus, there is no electric current (now DALI positive pole should be disconnected) from DALI negative pole, controllable silicon is turned off, the grid voltage of MOS switch is drawn high, MOS switch is turned on, increases sensor power network and be supplied to the power of DALI bus.
In the embodiment of Fig. 5 and Fig. 6, sensor power power supply for according to release can on coil the voltage of sensing to provide in DALI bus amplitude is different but electric current that polarity is identical.As it can be seen, the Zener diode having breakdown voltage to be 15V be connected to release can be between coil and aforesaid controllable silicon.When the voltage releasing energy coil offer is above this breakdown voltage, e.g. during 19V as depicted, Zener diode is breakdown, extra electric current is provided to aforementioned detection resistance, be equivalent to reduce silicon controlled excitation threshold, when electric current in DALI bus is relatively low in other words, controllable silicon also is able to excite, and the electric current provided in bus that therefore sensor power power supply is controlled is less.When the voltage releasing energy coil offer is less than this breakdown voltage, and the most only during 13V, Zener diode does not punctures, and does not therefore have extra electric current to be injected into detection resistance, so the electric current in bus that sensor power power supply is controlled is relatively large.
In fig. 5 and fig., further it is shown that polar protective circuit, it is connected to negative pole and the grid V of MOS switch of DALI busG.This polar protective circuit includes voltage detecting circuit, for detecting the voltage of negative pole of DALI bus, and is that MOS switch is disconnected by timing at the voltage of the negative pole of DALI bus.For more specifically, comprising: the base stage of audion is connected to the negative pole of DALI bus by bleeder circuit, the emitter stage of audion is connected to ground, and colelctor electrode is connected to the grid of MOS switch.If misconnection positive voltage in DALI bus, then audion will turn on, dragged down by the grid voltage of MOS switch so that MOS switch is closed.
In fig. 5 and fig., the power polarity in DALI bus provided due to sensor power power supply is constant, therefore can directly electrically connect between DALI receiver and DALI bus, without rectifier bridge.Eliminate the block diagram of DALI telecommunication circuit of rectifier bridge as shown in Figure 7.
In Figure 5, release described in and can have forward biased diode between coil and the positive pole of described DALI bus.And DALI receiver includes Zener diode and the optic coupling element of series connection, and the Zener diode of series connection and optic coupling element are connected to the anode of forward biased diode.The principle of this embodiment will be described with reference to Fig. 8.As shown in Figure 8, if DALI bus voltage is Vbus, the drain electrode of MOS switch to source voltage is Vds, according to aforesaid sensor power power supply for controlling the principle of the electric current in DALI bus, work as VbusGao Shi, MOS switch should be opened to provide power, therefore V in DALI busdsIt should be low-voltage；On the contrary, V is worked asbusTime low, DALI bus is shorted, and MOS switch should turn off, therefore VdsIt should be high voltage.So, with the voltage V in DALI busbusIt is reverse.Further, if the voltage that DALI receiver is received is Vx, VxAnd VdsFollowing relation should be met
Vsupp=Vx+Vds
So, VxWith VbusBeing in the same direction, therefore DALI receiver can correctly detect the voltage level in DALI bus, thus receives DALI signal.
This embodiment simplifies the structure of DALI receiver, it is not necessary to uses the protective resistance that resistance is the biggest, and can directly use the voltage in DALI bus to drive optocoupler.
