[accompanying drawing explanation]
Fig. 1 is LED drive power of the present invention structure principle chart in one embodiment;
Fig. 2 is LED drive power of the present invention structure principle chart in another embodiment.
[embodiment]
Below in conjunction with accompanying drawing, one detailed elaboration is done to specific embodiments of the invention.
As Fig. 1, LED drive power of the present invention, comprise filter rectifier, LED drive module, in addition, also comprise Bluetooth chip, the input termination AC power of filter rectifier, filter rectifier exports a road main power source and a road accessory power supply after carrying out rectifying and wave-filtering to AC power, main power source is powered to LED drive module, and accessory power supply is powered to Bluetooth chip;
Interconnective MCU and wireless transport module is provided with in described Bluetooth chip, the controling parameters that wireless transport module wireless receiving mobile terminal sends, and be transferred to MCU, MCU converts the controling parameters received to corresponding control signal and is transferred to LED drive module, and LED drive module works according to this control signal driving LED lamp.Described control signal can be pwm signal or analog signal etc.
The present invention takes full advantage of the MCU established in Bluetooth chip, does not need in addition to use independent MCU, only needs the partial function in the MCU that establishes in this Bluetooth chip of cutting, adds controlling functions of the present invention, control relatively simply, to provide cost savings.
The controling parameters that described mobile terminal sends can comprise the information such as scintillation time, switching time or scintillation time interval.MCU carries out being converted to corresponding control signal according to different controling parameters and is sent to LED drive module, thus the flicker of LED can be realized, or LED can be realized when opening, when turning off, or the scintillation time interval etc. of LED can be realized, can certainly carry out converting corresponding control signal to according to other parameter informations of mobile terminal.
During concrete enforcement, described wireless transport module is also for the SOS push button signalling of mobile terminal receive transmission, and be transferred to MCU, MCU converts corresponding control signal to according to this SOS push button signalling and sends to LED drive module, and LED drive module is glimmered by fixing scintillation time according to this control signal driving LED lamp.Thus the calling for help of distress signal can be realized by the flicker of LED.
Because the wireless transmission distance of Bluetooth chip is limited, in order to realize remote remote pilot, as Fig. 2, the present invention also comprises and also comprises power line carrier circuit, the coupled one end of this power line carrier circuit is between AC power and filter rectifier, the other end is connected with described MCU, and the feeder ear of this power line carrier circuit is connected with accessory power supply;
Carrier signal on this power line carrier circuit demodulates power line, and be transferred to MCU, MCU is converted to corresponding control signal according to this carrier signal and is transferred to LED drive module.Thus long-range remote pilot can be realized by power line.
During concrete enforcement, as Fig. 2, the present invention also comprises the memory be connected with MCU, stores the bluetooth ID of mobile terminal in memory;
When mobile terminal enters into the hunting zone of wireless transport module, the bluetooth ID of this mobile terminal is transferred to MCU by wireless transport module, whether the bluetooth ID stored in MCU searching storage is consistent with the bluetooth ID of this mobile terminal, if consistent, then MCU sends to LED drive module signal of turning on light;
When the hunting zone of mobile terminal not at wireless transport module, MCU sends pass modulating signal to LED drive module.Thus mobile terminal can be realized when entering in the hunting zone of Bluetooth chip, LED can be opened automatically, and when mobile terminal leaves the hunting zone of Bluetooth chip, LED automatically shuts down, and can realize the intelligentized control method of LED, and saves electric energy.
In addition, the controling parameters of this mobile terminal, when the controling parameters of mobile terminal being converted to corresponding control signal and being transferred to LED drive module, is also stored in memory by MCU, corresponding with the bluetooth ID of this mobile terminal;
While MCU sends to LED drive module signal of turning on light, also controling parameters corresponding for the bluetooth ID of this mobile terminal is sent to LED drive module.
Thus LED drive module according to controling parameters information-driven LED work last time of mobile terminal, can not need mobile terminal again to go to arrange controling parameters again, save the time, easy and simple to handle.If there is multiple mobile terminal, the priority level of the plurality of mobile terminal then can be set, the last time controling parameters information-driven LED work the highest according to priority level, needs to drive according to controling parameters information last time of multiple mobile terminal to prevent LED drive module.
In order to the power of testing circuit, voltage or current information, the present invention also comprises electric quantity monitoring circuit, the coupled one end of this electric quantity monitoring circuit is between AC power and filter rectifier, and the other end is connected with described MCU, and the feeder ear of this electric quantity monitoring circuit is connected with accessory power supply; This electric quantity monitoring circuit is used for the power of observation circuit, voltage or current information, and is transferred to MCU, and the power monitored, voltage or current information are transferred to mobile terminal by wireless transport module or are shown by display by MCU.Thus the power knowing this circuit, voltage or the current information that user can be allowed real-time.
Described electric quantity monitoring circuit also can be monitored on schedule, such as at a time monitors the power of circuit, voltage or current information, and presses the energy consumption of Fixed Time Interval counting circuit, such as every month to date energy consumption.
In addition, the control switch be connected with MCU can also be connected with between filter rectifier and main power source, when signal is turned on light in MCU output, control this control switch conducting; When MCU exports pass modulating signal, control this control switch and turn off, be equivalent to the supply of physical break main power source, the power supply of a reservation accessory power supply, keep the normal work of Bluetooth chip, power line carrier circuit or electric quantity monitoring circuit, thus can electric energy be saved.
