Description

Wireless related digital control lantern system and control method thereof

The present invention relates to a light control technology, and more particularly to a digital control lantern system for implementing coordinated operation of a plurality of lanterns by wireless association and a control method thereof.

Background technique

The digital control lamp is a controllable color lamp using a digital control circuit. The typical circuit shown in Fig. 1 includes a power source portion 104 and a controller 101, an electronic transformer 102, and an RGB three-color color light tube 103 (hereinafter referred to as a lantern). It is easy to control the color, brightness and contrast of the lantern at any time. The programmable digital control controller uses rewritable memory, which is convenient for different requirements of different customers or the same customer at different times. The manufacturer's personnel provide special programs or can be programmed by the customer. These digitally controlled lights are generally operated independently or in groups. There are currently two commonly used controllers on the market: single (A) controllers and seven (B) controllers; when using B controllers, seven (or seven) use the same controller for one group; when using the A-type controller, the output can also be connected in parallel with multiple (or branch) lights, up to 12 (or branches), but the lanterns operate in the same direction. In the case where a large venue requires multiple or more sets of lanterns to work simultaneously, the consistency of the working time of multiple or multiple sets of lanterns is difficult to guarantee. The general method is to add an internal synchronization device and an external clock synchronization source and a clock synchronization connection control line based on the independent or grouped numerical control lanterns. In this case, additional wiring (very useful) is required. Increasing the synchronization source brings a lot of inconvenience to the system modification, and increases the cost of special wiring and synchronization signal sources; and if there is a problem with the synchronization system, it may affect all the CNC lights. At the same time, the prior art controls multiple sets of lanterns through programming and setting methods, and only uses a special universal programmer for erasing and firing, so the rewritable memory needs to be taken out from the controller and inserted into the universal programmer. New programs and data are written to the memory by a computer connected to the universal programmer, which typically uses an external power supply. In the numerically controlled color lamp of this structure, when the rewritable memory is installed in the digital control lantern circuit, the program and data in the memory cannot be changed, the security of the program and data is ensured, and the system can work stably. . Reprogramming multiple times in this way will inevitably match the degree of the controller shell to the degree of bonding of the internal components and the chip.

Here, the A-type wireless associated controller is taken as an example to illustrate the composition thereof, and the wireless associated controller using the wireless associated controller is used. The circuit structure of the lantern is shown in FIG. 2. Compared with the existing controller of FIG. 1, the controller is based on the power circuit 202 of the original A-type controller, the intelligent control circuit 203 of the single-chip microcomputer, and the driving circuit 204. A synchronization pulse extraction circuit 202 is added for directly extracting a synchronization pulse from the power supply circuit 201 and outputting it to the intelligent control circuit 203 of the single chip microcomputer; the wireless correlation controller includes a power supply circuit 201, a synchronization pulse extraction circuit 202, a single chip intelligent control circuit 203, and Drive circuit 204. In addition, counters and software address registers (not shown) have been added to the software modules therein.

The power supply circuit 201 in the wireless correlation controller 200 has a circuit structure as shown in FIG. 3. The transformer T1 converts the commercial power into two 10-volt alternating currents, and one of the bypass signals I is led out to the synchronous pulse extraction circuit 202. The two-way 10 volt AC is then rectified and regulated to output power supply VCC. The above two-way 10 volt AC power is then subjected to rectification and filtering output power supply VCC. The circuit structure of the sync pulse extraction circuit 202 in FIG. 2 is as shown in FIG. 4. The 10 volt AC signal is reversely arranged through the paired input terminals, and the optocouplers connected to the output terminals are at the intermediate value of the AC signal at the zero level. A narrow pulse is output. Specifically, the present invention includes an AC coupling circuit R1, R2, C7, D4, D5 for connecting the above-mentioned 10 volt AC signal and two optical coupling elements U7 and U8 for extracting a sync pulse including a photodiode and a phototransistor. The working principle is shown in Figure 5: When the input signal voltage of the 50HZ/60HZ power supply is greater than the conduction voltage of the photodiode, the photodiode emits light, and the phototransistor is turned on. The component outputs a high level; when the input signal voltage is less than the on-voltage of the photodiode, the photodiode does not emit light, the phototransistor is turned off, and the optical coupling element outputs a low level. I is the signal processed by the AC voltage coupling circuit I through the AC coupling circuit. '

For the present typical A-type and B-type controllers, the present invention provides two types of wireless associated controllers, Type A and Type B. The circuit of the type A wireless associated controller is shown in Figure 6. The pl.3 port of the single-chip P87LPC764 receives the synchronous pulse signal T and counts it. When the software address is reached, the action instruction is obtained from the memory 24WC02, and is connected to the single-chip P87LPC764. The pl.0, pl.l and pl.2 ports of the RGB three-base color lamp drive circuit output RGB three-color optocoupler control pulse RI, GI, BI and RGB three-color optocoupler output signals RAI, GAI, BAI.

RAK G A1, B A1 : three-color optocoupler control pulse;

RI, GI, BI: three-color optocoupler output signal;

RO, GO, BO: Connect the three-color electronic transformer load;

COM: electronic transformer load sharing terminal;

When using a three-phase power supply, there is a phase difference of 120 °C between each phase, and there may be a certain time error between each controller. At this time, there is a quasi-synchronous relationship between the controllers.

2) Software Addressing: Since each controller uses a different time base address code. The discrete distribution control of multiple color tubes can be accomplished without a clock control line between the controllers. Software addressing includes static software addressing and dynamic software addressing.

M(a ^e T) (1)

M ... the natural number in the software address;

a ... the time constant in each action state function;

T ... power cycle.

This addressing method is suitable for the lighting landscape project in a linear configuration:

A(B)1 A(B)2 A(B)3 ...... A(B)N;

(where A and B are controller types and N is a natural number)

2 dynamic software addressing:

On the basis of the above, each controller uses a different time base address code in the work cycle, and the address code is obtained from the address list. The controller can be arranged in ascending or descending order of the initial action address code sequence.

This addressing method is suitable for the lighting landscape project of the planar array configuration:

A(B)11 A(B)12 A(B)13 ...... A(B)1N A(B)21 A(B)22 A(B)23 ······ A(B)2N

A(B)31 A(B)32 A(B)33 A(B)3N
