Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Please refer to Fig. 1, some illumination control methods based on electric power direct current the following steps are included:
Step S1, in the information of control terminal input control, the modulates information to electric power direct current；
Step S2, the information is obtained from electric power DC electrolysis modulation in controlled end；
Step S3, controll plant receives and then executes the information.
In step sl, by the modulates information to the method for electric power direct current the following steps are included: the information is compiled
Code forms binary first Serial No.；First Serial No. is modulated to the electric power direct current.
Wherein, the information includes metric address and metric data, and the data include but is not limited to light
Luminance information, information of turning on light, information of turning off the light.Such as: in some embodiments, the range of address is 0-20, is indicated when address is 0
Broadcast；Data area is 0-100, indicates to turn off the light when data are 0, indicates to turn on light when data are 1, data are bigger, and brightness is bigger.
The method of the coding are as follows: first by the metric address multiplied by a constant, then it is added with the metric data,
Obtain a metric coded number；Next the metric coded number is converted into binary coded number；Finally exist
Parity check bit is added in binary coded number, obtains first Serial No..
Assuming that: address 4, light modulation data are 85, and constant 101, then cataloged procedure is as follows: firstly, passing through operation 4*101
+ 85=574 obtains metric coded number 574, next, being converted into binary coded number 0,010 0011 for 574
1110,0,010 0011 1110+0 of parity check bit then is added in binary coded number 0,010 0,011 1110, obtains
First Serial No. 0,100 0,111 1100.
Assuming that: address 12, when light modulation value is 99, constant 101, then cataloged procedure is as follows: firstly, passing through operation 12*
101+99=1311 obtains metric coded number 1311, next, being converted into binary coded number 0101 for 1311
0001 1111,0,101 0001 1111+1 of parity check bit then is added in binary coded number 0,101 0,001 1111,
Obtain the first Serial No. 1,010 0,011 1111.
The following detailed description of three kinds of modes that first Serial No. is modulated to the electric power direct current.
The first modulation system are as follows:, in this way will be described with the high level characterization 1 of electric power direct current, low level characterization 0
Everybody of first Serial No. is sequentially modulated in the electric power direct current.As illustrated in fig. 2, it is assumed that the first Serial No. 1 is
0100100110, the voltage of electric power direct current 2 is 200V, high level 200V, low level 180V, and level width is 100 millis
Second, according to the waveform of the modulated electric power direct current of the first modulation system as shown in label 3 in Fig. 2.
Second of modulation system are as follows:, in this way will be described with the high level characterization 0 of electric power direct current, low level characterization 1
Everybody of first Serial No. is sequentially modulated in the electric power direct current.As shown in Figure 3, it is assumed that the first Serial No. 1 is
0100100110, the voltage of electric power direct current 2 is 200V, high level 200V, low level 180V, and level width is 100 millis
Second, according to the waveform of the modulated electric power direct current of second of modulation system as shown in label 3 in Fig. 3.
The first above-mentioned modulation system and second of modulation system are all (i.e. high with the multilevel type of the electric power direct current
Level, low level) characterization 0 and 1.
The third modulation system are as follows: 0 and 1 is characterized with the level width of the electric power direct current, in this way by described the
Everybody of one Serial No. is sequentially modulated in the electric power direct current.It is assumed that the first Serial No. 1 is
0100100110, the voltage of electric power direct current 2 is 200V, characterizes 1, m milliseconds of width level characterizations 0 with n milliseconds of width level, presses
The waveform of the modulated electric power direct current of this mode is as shown in label 3 in Fig. 4.
In the first above-mentioned modulation system and second of modulation system, since level width is fixed, the first number
The digit of sequence is fixed, thus no matter the value of information (decimal number) be it is how many, modulation the time be it is fixed, i.e., 10
Level width, it is assumed that level width is 100 milliseconds, then the modulation time of the first Serial No. is 1 second.In the third above-mentioned modulation
In mode, due to the digit of the first Serial No. be it is fixed, level width only has m and two kinds of n, it is assumed that m is 100 milliseconds, and n is
200 milliseconds, thus no matter the value of information (decimal number) be it is how many, the modulation time of the first Serial No. 1 second to 2 seconds it
Between.Remove parity check bit, 9 bits of the first Serial No. can indicate 512 numerical value, it can expression 1,2,
3 ..., 510,511,512 totally 512 decimal numbers, and if directly characterized with level width with existing modulation system
These decimal numbers, then digital 1 corresponding level width is 100 milliseconds, the modulation time needed is 100 milliseconds, 2 pairs of number
The level width answered is 200 milliseconds, and the modulation time needed is 200 milliseconds, and digital 3 corresponding level width are 300 milliseconds, is needed
The modulation time wanted is 300 milliseconds, and so on, digital 512 corresponding level width are 51200 milliseconds, when the modulation needed
Between will be up to 51.2 seconds.It can be seen that using modulator approach of the present invention, modulates information time and transmission time will be greatly shortened,
And information value is bigger, and effect is more obvious, after being applied to control system, it is ensured that sensitivity of control system.
On the other hand, this modulator approach scalability is good.First Serial No. increases by one, so that it may keep capacity (controlled right
The quantity of elephant) it doubles.By 210=1024,211=2048,212=4096 it is found that the binary number with ten can indicate
1024 information can indicate 2048 information with 11 binary numbers, can be indicated with 12 binary numbers
4096 information, and so on, it can be seen that binary Serial No. is every to increase by one, and denotable information content will
It doubles.In this modulator approach, due to converting the information into binary first Serial No., then by the first digital sequence
Column are modulated to electric power direct current, then only the digit of the first Serial No. need to be increased by one, the quantity for the information that can be indicated
It will double, and after increasing by one, the modulation time of the first Serial No. only needs to increase by 100 milliseconds or 200 milliseconds, changes speech
It, it is only necessary to increasing less modulation and transmission time can be such that capacity (quantity of controll plant) doubles, therefore use this tune
Method processed is with good expansibility, and is very suitable to the more occasion of controll plant, such as subway station, the public field in megastore
Institute.
Above by specific embodiment, invention is explained in detail, these detailed description are only limited to help
Those skilled in the art understand that the contents of the present invention, can not be interpreted as limiting the scope of the invention.Art technology
Personnel should be included in protection model of the invention to various retouchings, the equivalent transformation etc. that above scheme carries out under present inventive concept
In enclosing.
