Technical field

The present invention relates to integrated circuit, circuit hardware design and Embedded Software Design, PC software and algorithm design, Communications And Computer integration field, utilize advanced communication and digital power technology, WiFi module and accurate voltage current detecting module, live wire speed-sensitive switch module are integrated on control panel (traditional switch panel). Control instruction is encoded, by the speed-sensitive switch of live wire, control instruction is sent in electrical equipment, thus controlling the operation of electrical equipment; Meanwhile, on the control panel the electricity consumption of equipment is carried out data acquisition, by advanced algorithm and high-precision data acquisition module, it is thus achieved that the electricity consumption data of each equipment, and analyze the electric leakage data obtaining power cable live wire and zero line accordingly; If electric leakage exceedes preset upper limit, then send alarm, start linkage reaction simultaneously, as cut off the operations such as live wire. According to different application demands, the control of electrical equipment can be single addressing by control panel, it is also possible to is packet addressing; Controlled electrical equipment can be low power, it is also possible to is powerful, it is possible to is the electrical equipment of same type, it is also possible to is multiple different types of electrical equipments; Control can touch on panel, it is also possible to is completed by mobile phone A PP. This system can directly replace existing switch panel without change wiring, can realize the scene control to electrical equipment such as intelligent domestic, wisdom building.

Technical background

The control of the electrical equipment of current intelligent domestic and wisdom building, is generally adopted two ways: remote switch controls; Bus control unit or wireless controller, thus realizing the control to individual equipment or one group of equipment.

No matter which kind of control mode, is all based on the transformation of the Traditional control pattern to equipment, and bus mode needs rewiring, and wireless mode needs to increase a wireless module in each electrical equipment. ZigBee module data rate is low, and WiFi module is subject to several quantitative limitations of wireless access point AP, cannot normal operation under the scene that electrical equipment is a lot. Current system is as shown in Figure 1.

Annexation is as follows: 220VAC is accessed and is connected with the AC-DC module 24VDC of electrical equipment and control unit by power cable, control unit is connected with bus cable with electrical equipment by MCU bus marco module, or is wirelessly connected with electrical equipment by wireless module.

Work process is as follows; Electrical equipment, after obtaining 220VAC electric power, waits that control unit issues the instruction of switch; Control unit is by pre-set programs or accept external command, with bus or wireless mode by instruction issuing to electrical equipment; Electrical equipment is according to instruction, and the power supply of conducting or cut-out 220VAC, thus controlling the duty of electrical equipment: stopped status or duty.

Current control system is a kind of extension of traditional control method, and the control of the inner parameter remaining on off state or little equipment of control is unsatisfactory for the new demand of the application scenarios day by day increased; There is no data acquisition function, the state of electrical equipment is known little about it; Need change wiring or in electrical equipment, increase wireless module, constructing not easily, and cost is high.

The major defect of current system is:

Control mode and content are single. Carrying out switching manipulation rather than user oriented application scenarios only for each loop, each equipment, a key control pattern of the different control content of the different types of electrical equipment of a corresponding scene is difficulty with.

There is no data acquisition function. Only achieve on-off control, but the electricity consumption data etc. of the state of electrical equipment, equipment runnability, equipment do not have data acquisition; Switch conduction, it is unknown whether equipment can run.

The physics realization cost of control method is high, is not suitable for transformation project or plug and play mode. Bus mastering mode needs increase bus cable in application places and construct; Wireless mode needs to increase a wireless module for each electrical equipment. The ZigBee adopting data rate low cannot be carried out quickly complicated control, and WiFi limits cannot adopt on a large scale due to the access quantity of access point AP.

Different electrical equipments needs different control modes and controls parameter, and control unit structure is complicated. Electrical equipment type is different, and the content of control is different with parameter. Control for each electrical equipment, it is necessary to independent control module.

Safety is low. There is no real-time data acquisition and analysis, during to the operational factor of electrical equipment with state, the service behaviour of power cable, electricity consumption, whether relevant human users normal, whether working space electric power environmental meets job requirement etc., not having any surveillance and control measure, the running safety of whole system is low.

Present invention

The present invention realizes by the following method.

Being illustrated in figure 2 the transmission of electricity based on quick alternating-current switch and control integration wisdom system block diagram, system is divided into two parts: wisdom panel and controlled electrical equipment.

Wisdom panel annexation is: 220VAC access interface, after current-voltage transformer, is connected with speed-sensitive switch 1, speed-sensitive switch 2, speed-sensitive switch 3; After current-voltage transformer and 16��24bit, more than 32KSMPS ADC module connect, access ARM32MCU, ARM32MCU module and be connected with WiFi module, touch button module and speed-sensitive switch 1, speed-sensitive switch 2, speed-sensitive switch 3 simultaneously.

Controlled electrical equipment is for 3: LED colored lamp, power window, electrically driven curtain.

LED colored lamp annexation is: 220VAC accesses module and is connected through the light source assembly of power supply module with LED colored lamp, and 220VAC accesses module and is connected with MCU through signal transformer, and MCU connects control module, controls module and is connected with LED colored lamp.

Power window annexation is: 220VAC accesses module and is connected with power window through power supply module, and 220VAC accesses module and is connected with MCU through signal transformer, and MCU connects control module, controls module and is connected with power window.

Electrically driven curtain annexation is: 220VAC accesses module and is connected with electrically driven curtain through power supply module, and 220VAC accesses module and is connected with MCU through signal transformer, and MCU connects control module, controls module and is connected with electrically driven curtain.

Speed-sensitive switch 1 module of wisdom panel accesses module with the 220VAC of LED colored lamp and signal transformer module is connected in power cable mode; Speed-sensitive switch 2 module of wisdom panel accesses module with the 220VAC of electrically driven curtain and signal transformer module is connected in power cable mode; Speed-sensitive switch 3 module of wisdom panel accesses module with the 220VAC of power window and signal transformer module is connected in power cable mode.

Operation principle is: wisdom panel passes through WiFi or touch button, it is thus achieved that the control instruction to equipment; Control instruction is converted to the PWM waveform of N system by ARM32MCU module, is directly controlled the break-make of 220VAC power cable by speed-sensitive switch, and control instruction is transferred to corresponding electrical equipment; Electrical equipment was connected power cable and was obtained electric energy, took out PWM waveform by signal transformer simultaneously, and the waveform of taking-up is decoded by MCU module, it is thus achieved that the control instruction of electrical equipment; MCU exports control instruction to controlling module accordingly, thus controlling the operation of electrical equipment.

Wisdom panel obtains the data of the live wire L and zero line N of 220VAC by current-voltage transformer, simultaneously, according to the ARM32MCU switching manipulation to the different time of each electrical equipment on different speed-sensitive switches and each speed-sensitive switch, obtain the electricity consumption data of each electrical equipment on each loop and loop, after data result Algorithm Analysis, identify the presence or absence of the problems such as electric leakage is transfinited, load is transfinited, start combined operation to connect as cut off corresponding live wire, and data are delivered to by WiFi other data handling equipment on network.

Each electrical equipment has multiple ID: about the unique EID of oneself, and be under the jurisdiction of the different GID of multiple packet. EID and the GID of relevant electrical equipment, and the annexation of they and speed-sensitive switch, be stored in the internal memory of ARM32MCU. ARM32MCU, according to this connection relational table, starts corresponding speed-sensitive switch module, control instruction is issued.

Wisdom panel adopts increment (decrement) pattern, and the equipment on each speed-sensitive switch loop and loop is carried out data acquisition. Conducting speed-sensitive switch 1, closing high-speed switch 2 and speed-sensitive switch 3, it is thus achieved that the electricity consumption data in speed-sensitive switch 1 loop; Conducting speed-sensitive switch 1 and speed-sensitive switch 2, closing high-speed switch 3, it is thus achieved that the electricity consumption data in speed-sensitive switch 1 loop and speed-sensitive switch 2 loop. Both data will subtract each other, then obtain speed-sensitive switch 1 loop, speed-sensitive switch 2 loop electricity consumption data respectively. Multiple electrical equipments on each speed-sensitive switch loop, it is possible to by addressing the independent of each electrical equipment on this loop thus controlling its duty, it is thus achieved that delta algorithm data, and then obtain the electricity consumption data of each electrical equipment.

Use in electric data collecting actual, according to instructions different in practical application, it is possible to obtain corresponding electrical equipment data, it is not necessary to design is not belonging to the independent data acquisition module of practical ranges. Once the work order of certain electrical equipment is given, but wisdom panel itself can't detect the change of any operating current, then assert that this equipment is in malfunction, and relevant alert data is sent on network by WiFi.

Live wire L on wisdom panel and the output of zero line N, it is possible to connect various electrical equipment, it is also possible to connect socket. By the accurate measurement to the electric current on live wire L and zero line N, identify the various leakies in using electricity system. When electric leakage (containing getting an electric shock) reaches preset upper limit, then turn off corresponding electricity consumption loop, to avoid the generation of accident. The detection method of electric leakage will carefully be stated in the description in fig. 5.

Advantages of the present invention is:

Compatible with traditional control mode. Use the direct substitution traditional switch panel of wisdom panel, be originally arranged on the electrical equipment on switch panel, it is possible to obtain and original the same switch control functions; After changing wisdom panel, if using the electrical equipment with system compatible, such as LED colored lamp, then this LED colored lamp can be addressed separately and control, and control content more abundant accordingly, as color, colour temperature, illumination, flicker etc. are all controlled.

The control of each branch road is independent mutually, both can synchronize, it is also possible to asynchronous. On each wisdom panel, each speed-sensitive switch loop is corresponding to a PWM output port of ARM32MCU; The quantity of the PWM output port of ARM32MCU can set that to be 1��32 as required; The control of each road PWM output is individually carried out by ARM32MCU, both can synchronize, it is also possible to set the control instruction delay time between every road thus asynchronous carrying out.

The accuracy of data acquisition of electrical equipment is high, and speed is fast. As long as changing wisdom panel, then no matter whether electrical equipment is compatible with native system, can be all unit according to loop, it is thus achieved that electricity consumption data. The collection of electricity consumption data adopts 24bit precision, more than 48K sample frequency, and precision is fast at high speed; In ARM32MCU, electricity consumption data use the internal calculation mode of 32bit. Maximum current such as certain loop is set to 50A, then within the precision of sampled data can reach 4uA.

Drain conditions can be monitored in real time, it is prevented that electric shock accidents occurs. Aging at power cable insulation layer, and when immersion, human electric shock, it may occur that the electric current to locally connected (GND) of live wire L and zero line N, thus causing not mating of the size of electric current on live wire L and zero line N, phase place etc. Wisdom panel can analyze the loop obtaining electric leakage in real time, reaches preset upper limit and then automatically cuts off corresponding current supply circuit.

One key control pattern of application-oriented scene, and it is not only the control for individual equipment. The traditional control for equipment supported by wisdom panel, such as light fixture, curtain, door and window, air-conditioning etc., also supports the key control pattern towards application scenarios. Each scene mode can comprise multiple different types of electrical equipment, and the control content of each electrical equipment changes according to scene difference, and 1 wisdom panel can control maximum 16 different application scenarios; The equipment such as the PC on mobile phone A PP and network supports more scene modes, equipment in scene and the control content of equipment, all can formulate voluntarily; Mobile phone A PP and PC etc. are minimum supports 4K different application scenarios.

Detailed description of the invention

Below in conjunction with drawings and Examples, present disclosure is described in further detail.

Such as Fig. 3 institute small-power wisdom panel schematic diagram, annexation is: live wire L is connected with N number of choke coil (choke coil 1, choke coil 2, choke coil N) one end through voltage transformer VS2 summation current transformer CS2, the other end of N number of choke coil is connected with the input of alternating-current switch ACS1, ACS2, ACSN respectively, and the outfan of alternating-current switch ACS1, ACS2, ACSN is connected with fire wire output end Lout-1, Lout-2, Lout-N respectively; Zero line N, through voltage transformer VS1 summation current transformer CS1, is directly output to the zero line N-port of wisdom panel, mates with multiple fire wire output end mouths. Voltage transformer VS1, VS2 summation current transformer CS1, CS2, respectively through voltage x current mutual inductance matched interfaces circuit, access 24bit48KSMPS4CHADC module, and ADC module, in I2S or L+R mode, is connected with ARM-COREMCU; ARM-COREMCU module is connected with WiFi module, touch button module, and PWM1, PWM2, PWM3 are by driving interface module in its output, are connected with the control end of alternating-current switch ACS1, ACS2, ACSN respectively.

Operation principle is: voltage current transformer VS1, CS1 are to zero line N, voltage current transformer VS2, CS2 are to live wire L, carry out the sampling of voltage x current respectively, by voltage x current mutual inductance matched interfaces circuit, sampled signal being sent to 4 passage ADC module 24bit48KSMPS4CHADC be digitized respectively, corresponding data is input to ARM-COREMCU process by I2S bus or L+R mode.

Data after process are sent to network by WiFi by ARM-COREMCU module, or receive control instruction by WiFi and touch button module, it is the pwm signal of different circuit by control command code, exported by pin PWM1, PWM2, PWM3 of ARM-COREMCU chip, pwm signal is after interface circuit switching levels of overdriving, control the break-make of alternating-current switch ACS1, ACS2, ACSN, thus control instruction being issued to the distinct device of different circuit.

The voltage x current of live wire L and zero line N is sampled by wisdom panel respectively, obtains various data thus calculating, including but not limited to bearing power, the current waveform of load, the voltage waveform of power cable, electric leakage data etc. The zero line N voltage x current when 3 phase load equilibrium is 0; In actual applications, 3 phase load equilibriums can not realize. Sampling by the voltage x current to zero line N, it is possible to obtain the data that 3 phases are balanced, and the difference of the phase place between each phase load.

High-power wisdom panel schematic diagram as shown in Figure 4 A, connecting relation is: live wire L is connected with N number of choke coil (choke coil 1, choke coil N) one end through voltage transformer VS2 summation current transformer CS2, the other end of N number of choke coil is connected with the input of the input of alternating-current switch ACS1, ACSN and relay 1, relay N respectively, and the outfan of alternating-current switch ACS1, ACSN is connected with relay 1, the outfan of relay N and fire wire output end Lout-1, Lout-N respectively; Zero line N, through voltage transformer VS1 summation current transformer CS1, is directly output to the zero line N-port of wisdom panel, mates with multiple fire wire output end mouths. Voltage transformer VS1, VS2 summation current transformer CS1, CS2, respectively through voltage x current mutual inductance matched interfaces circuit, access 24bit48KSMPS4CHADC module, and ADC module, in I2S or L+R mode, is connected with ARM-COREMCU; ARM-COREMCU module is connected with WiFi module, touch button module, and its output PWM1, PWM2, PWM3, PWM4, by driving interface module, are connected with the control end controlling end and relay 1, relay N of alternating-current switch ACS1, ACSN respectively.

Data after process are sent to network by WiFi by ARM-COREMCU module, or receive control instruction by WiFi and touch button module, it is the pwm signal of different circuit by control command code, exported by pin PWM1, PWM2, PWM3, PWM4 of ARM-COREMCU chip, pwm signal, after interface circuit switching levels of overdriving, controls the break-make of alternating-current switch ACS1, ACSN and relay 1, relay N.

Owing to being operated under big current-mode, the caloric value of semiconductor AC switch ACS is very big, it is easy to cause overtemperature protection to turn off, and therefore adopts the mode that relay is in parallel with ACS, it is ensured that current work is normal greatly. When normal operation, relay turns on and semiconductor AC switch ACS cut-off; When instruction is transmitted, relay ends and semiconductor AC switch ACS speed-sensitive switch, had both transmitted energy, and had also sent instruction.

Under different duties when entrance or exit instruction transmission, the work schedule that relay switchs with semiconductor AC is different. When load does not work, control panel switchs ACS first with semiconductor AC and sends instruction, then opens relay, turns off semiconductor AC switch ACS, allow load enter normal duty after time delay; At load normal operation, it is necessary to when issuing new instruction, first turn on ACS, be then powered off relay, after time delay, send instruction by ACS, then turn-on relay, then after time delay, turn off semiconductor AC switch ACS.

High-power wisdom panel workflow as shown in Figure 4 B, upon power-up of the system, first determining whether that whether the load in certain loop is the compatible load that can details be controlled of native system, iff compatibility without custom-designed control interface, system is converted to traditional mode switching control; If load possesses details control ability, and power is relatively big, then need according to Fig. 4 A method illustrated, while allowing equipment normal operation, switch between ACS at relay and semiconductor AC, accurately control according to sequential, in order to instruction can accurately transmit.

The switching speed of semiconductor AC switch ACS is typically in 10KHz; conduction impedance is at 1��5 ��; when load current is when 10A; the heating power of semiconductor AC switch ACS is more than 100W; it is easy to burn semiconductor AC switch ACS; or the automatic protection mechanism of triggered semiconductor alternating-current switch ACS, causes that load can not work. The conduction impedance of relay is at 1��5m �� or less, and when bearing power is bigger, heating power is only small, it is possible to long-time holding load work.

To switch ACS than semiconductor AC more slowly for the speed that switches off and on of relay, and the difference of each relay is very big; Accurate delivery for the normal operation of proof load and instruction, it is necessary to switch at relay and semiconductor AC and between the State Transferring of ACS, enough time delays are set.

Detection of electrical leakage schematic diagram as shown in Figure 5, through the data acquisition of wisdom panel, electric current and voltage by Precision measurement. 220VAC voltage is by after 24bitADC digitized, it is possible to the minimum voltage of resolution is within 1mV; The electric current of 50A is by after 24bitADC digitized, it is possible to the minimum electric current of resolution is within 50uA.

Monophase electric power leakage mode has 3 kinds: live wire L electric leakage, zero line N electric leakage, live wire L and zero line N leak electricity simultaneously; Monophase electric power human electric shock's pattern has 3 kinds: live wire and locally electric shock between GND, zero line N and locally electric shock between GND, electric shock between live wire L and zero line N.

By detecting the electric current whether equal (or error is in prescribed limit) on live wire L and zero line N, and whether phase place and size meet pattern when not leaking electricity, it may be determined that whether 2 kinds of leakage modes and 2 kinds of electric shock patterns exist. The Monophase electric power leakage mode detected 2 kinds: live wire L electric leakage, zero line N electric leakage; The Monophase electric power human electric shock's pattern 2 kinds detected: live wire and locally electric shock between GND, zero line N and locally electric shock between GND.

Electric leakage between live wire L and zero line N and human electric shock, identify in the following manner: whether the difference of the data when data of the related load that (1) is in running order and nearest normal operation is more than preset upper limit; (2) turn off the load in this loops all, exist still more than the electric current of the upper limit between live wire L and zero line N.

For 3 mutually nonequilibrium duties, zero line N and locally between GND, voltage difference should be detected, as zero line N and locally between GND, voltage within 36V, is then place of safety; As zero line N and locally between GND, voltage more than 36V, is then non-security district. This detection needs locally GND to access in wisdom panel.

4 scale coding legend as shown in Figure 6A, switchs the ability of ACS, carries out 4 scale codings in the way of different PWM according to semiconductor AC. Pulsewidth 100us is encoded to A, pulsewidth 200us and is encoded to B, pulsewidth 400us and is encoded to C, and pulsewidth 800us is encoded to D.

Coding is N system, explains with 4 systems.

4 scale codings transmission schematic diagram on power cable as shown in Figure 6B, in an ac period of 50Kz, sends 84 scale coding information (being equal to 16 2 scale coding information).

3ms after zero-crossing of alternating current being detected, every 1ms send 4 scale coding information, altogether need 4ms to be sent, and then keep the next zero-crossing of alternating current of mourning in silence of 3ms.

At positive half cycle and the negative half period of alternating current, send 4 scale codings in the same manner.

The coding sent is in every 1ms time frame, it is possible to be left alignment, it is also possible to be right alignment, or intermediate alignment.

One complete instruction needs 16 4 scale codings (32 2 scale codings), completes in 2 ac periods of continuous print; Send the beginning half cycle of instruction, regardless of positive and negative.

Control instruction decoding schematic diagram as shown in Figure 6 C, connection relation is: former limit on the left of signal transformer T1, is connected with live wire L, zero line N respectively through resistance R1, R2, and transformator is in parallel with resistance R4 to guarantee that signal transformer original edge voltage does not exceed standard; On the right side of signal transformer, the two poles of the earth meet diode D5, D6 respectively and are connected to load R3 with detecting way, and on the right side of transformator, the centre tap of output is then ground wire.

The input resistance R5 of band filter BPFilter is connected with resistance R3; The other end of R5 accesses the positive input terminal of operational amplifier by electric capacity C1, is accessed the outfan of operational amplifier by resistance R9; The positive input terminal of operational amplifier passes through electric capacity C2, resistance R6 ground connection; The negative input end of operational amplifier passes through R7 ground connection, is accessed the outfan of operational amplifier by R8.

The input of the output welding wave shaping circuit of BPFilter.

Operation principle is: carrying the 220VAC AC signal of speed-sensitive switch instruction, after signal transformer and detecting circuit, power frequency 50Hz is attenuated, and speed-sensitive switch signal is held essentially constant, and is converted into unidirectional pulse; After BPFilter module, power frequency 50Hz is further attenuated, and speed-sensitive switch signal is strengthened; Then signal is processed by waveform shaping circuit, restores original coding signal.

Signal after coding is through transmission decoding, and original pulsewidth can offset, and by the fault-tolerant of +/-25% and training sequence mode, transmission channel is calibrated accordingly.

The coded command of color LED light fixture as shown in Figure 7, illustrates the coding of 16 4 systems with this, how to realize the accurate control to LED colored lamp.

New system application schematic diagram as shown in Figure 8, connection relation is: smart mobile phone is directly connected with home gateway by WiFi, or Fig. 3 G, 4G, 5G wireless network connects into Telecommunications Services, Inc, the broadband networks of registering one's residence (3G, 4G, optical fiber) then passing through telecommunications company is connected with home gateway; Home gateway is connected with intelligent appliance, wisdom switch panel (wisdom panel), wisdom socket by WiFi mode; Wisdom switch panel (wisdom panel) is directly connected with toning dimming LED lamp, ordinary lamp and lantern, electrically driven curtain, power window, common socket etc. with power cable.

Operation principle is: control instruction is sent to home gateway by WiFi by smart mobile phone, or by the broadband network of telco provider as intermediary, is connected to home gateway; Home gateway sends an instruction to intelligent appliance, wisdom socket or wisdom switch panel, controls the operation of relevant device; Control instruction is translated as on the control instruction of certain equipment of certain branch road or several branch road the combined command of multiple equipment by wisdom switch panel (wisdom panel), sends instructions to relevant device by power cable; Accept the equipment such as light modulation toning LED lamp, power window, electrically driven curtain etc. of instruction, the size of controlled content and controlled quentity controlled variable is obtained according to system command decoding, implement to control, angle etc. such as the open degree of the color of light fixture, power and electrically driven curtain, shutter, or legacy powered device is carried out common switching manipulation, the switch etc. of switch or common socket as controlled ordinary lamp and lantern.

Relevant data and warning message, transmit machine in one's hands from home gateway by WiFi; Or by intermediary of telco provider, the data of collection and warning message are sent to mobile phone.

As shown in Figure 9 based on the color LED light fixture theory diagram of new system, connection relation is: the live wire L and zero line N of 220VAC accesses AC-DC module 24VDC, series connection simultaneously accesses resistance R1, R2 and accesses the former limit of signal transformer, and the parallel connection of signal transformer former limit accesses resistance R4; The output of AC-DC module 24VDC connects the PWM interface of electric capacity C1, C2 and inductance L1 and MCU; The other end of inductance L1 is connected with NMOS1 drain electrode, is connected with the P pole of diode D3; The N pole of diode D3 is connected with electric capacity C3, C4, and is connected with the P pole of the source electrode of PMOS1, light emitting diode W; Light emitting diode W, R, G, B connect and the N pole ground connection of B; PMOS1, PMOS2, PMOS3, PMOS4 are in parallel with light emitting diode W, R, G, B respectively. The grid of PMOS1, PMOS2, PMOS3, PMOS4 is connected with PWM2, PWM3, PWM4, PWM5 of MCU output interface respectively, and the output interface PWM1 of the grid of NMOS1 and MCU.

After secondary the two poles of the earth of signal transformer T1 meet diode D1, D2, being connected with resistance R3 and carry out detection, the secondary centre tap of signal transformer T1 draws ground connection GND; R3 one end ground connection, other end is connected with the N pole of waveform shaping circuit and diode D1, D2, and the output of waveform shaping circuit is connected with MCU.

Operation principle is: the 24VDC that 220VAC input is changed into voltage constant is exported at electric capacity C1, C2 by AC-DC module, the outfan PWM1 of MCU controls the grid of NMOS, according to pulsewidth, certain power is transformed on electric capacity C3, C4 by inductance L1 and diode D3, power consumption on C3, C4 is on light emitting diode W, R, G, B, it is thus achieved that the lighting environment that application scenarios needs.

Output interface PWM2, PWM3, PWM4, PWM5 of MCU control the conducting of PMOS1, PMOS2, PMOS3, PMOS4 respectively; Once corresponding PMOS transistor conducting, then light emitting diode in parallel with it will be bypassed, and no longer luminous. If PWM5 is 0, then PMOS1 conducting, then light emitting diode W is bypassed, and the energy on electric capacity C3, C4 is consumed on light emitting diode R, G, B. Now, the PWM1 output of MCU controls the break-make of NMOS1 transistor, and from electric capacity C1, C2, corresponding energy is transformed into electric capacity C3, C4 by inductance L1 and diode D3.

The size of luminous power is exported by the PWM1 of MCU and determines, and the combination of luminous content is by the logic control of PWM2, PWM3, PWM4, PWM5, has combination 16 kinds different. Different tones is then by the ratio-dependent of the pulsewidth of PWM2, PWM3, PWM4, PWM5. Whether the pulsewidth of PWM1, PWM2, PWM3, PWM4, PWM5 and PWM2, PWM3, PWM4, PWM5 turn on, the instruction issued determine.
