Description

A kind of method of 485 bus ID decimal codeds in intelligent illuminating system

Technical field

The present invention relates to intelligent lighting fields, and in particular to one kind is for the 485 bus ID decimal systems in intelligent illuminating system The method of encoding setting.

Background technique

To meet more power saving, energy conservation, modern intelligent lighting demand easy to use, more and more office buildings, industry park, Square, hospital, school, hotel use 485 bus type intelligent lighting system solutions.Such scheme requires engineering peace Unique ID code setting is carried out from equipment to the numerous of 485 buses of access when dress, existing 485 bus ID encodes implementation method master There is following two:Using toggle switch binary coding mode；Using rotary dip switch decimal coded mode.

For the above method, carry out ID encoding setting in engineering and when failure is verified be inconvenient, reason be two into The ID coding of sample preparation formula is not very intuitive for people and is difficult to fast and accurately identify ID number, and rigging up and debugging is caused to work Inefficiency.

For the above method, equipment manufacturing costs obviously increase, and manufacturer's profit is substantially damaged, and reason is rotatably to dial Code switch price is more than ten times of common toggle switch price.

Therefore, a kind of low cost and both intuitive and simple easy-to-use 485 bus ID encoding setting method are found, this is become Field technical staff's one of the technical problems that are urgent to solve.

Summary of the invention

The technical problem to be solved in the invention is: proposing a kind of for the 485 bus ID decimal systems in intelligent illuminating system The method of encoding setting solves the technical problem that the work of 485 bus ID encoding settings is complicated, cost of implementation is high in the prior art.

The present invention solve above-mentioned technical problem the technical solution adopted is that:

Step 1,4 toggle switch are distributed for each numerical digit of 485 bus decimal system ID numbers, and establishes toggle switch position generation The position 1,2,3,4 of table numerical tabular, i.e. toggle switch successively represents numerical value 1,2,3,4 at the position ON, represents number in OFF position Value 0, every totally 2 kinds of combination；

Step 2, the value for establishing each numerical digit of decimal system ID number represents the relational expression of numerical value with corresponding 4 toggle switch positions 1,2,3,4, Specifically: the value of each numerical digit of ID number be equal to corresponding toggle switch position 1,2,3,4 represent the summation of numerical value again divided by 10 remainder；

Step 3, each toggle switch is electrically connected to 485 bus ID detection single-chip microcontroller, and by high-order area to the suitable of low level area Sequence carries out location layout from left to right and completes the design of 485 bus ID number reading programs, to realize based on 4 toggle switch Function is arranged in 485 bus ID decimal codeds.

It so far, can be according to the position of toggle switch when we carry out 485 bus ID encoding setting in installation The guide of character 1,2,3,4 is identified, and determines the switch for stirring those to ON by addition mental arithmetic within simple ten It sets, to fast and accurately complete the encoding setting task of wanted ID number.

The invention has the benefit that the present invention, which innovatively proposes one kind, realizes 485 bus ID based on 4 toggle switch The method of decimal coded setting, so that the work of 485 bus ID encoding settings becomes to be simple and efficient, to substantially increase equipment The efficiency of installation and debugging, and thickened the profit of device fabrication manufacturer.

Detailed description of the invention

Fig. 2 is a kind of embodiment of the invention with reference to figure

Specific embodiment

With reference to the accompanying drawings of the specification to 485 bus ID decimal coded method methods in intelligent illuminating system of the present invention into The detailed explanation and illustration of row.

As shown in attached drawing 1,2, the invention particularly discloses 485 bus ID decimal codeds in a kind of intelligent illuminating system to set The method set, this method are applicable to using the application such as the intelligent illuminating system of 485 bus group-network constructions or industrial control system Occasion.This method specifically comprises the following steps.

Step 1,4 toggle switch are distributed for each numerical digit of 485 bus decimal system ID numbers, and establishes toggle switch Position represents numerical tabular, as shown in figure 1 shown in the table of step 1.Implementation example figure 2 is 2 485 bus decimal system ID numbers, supports 0 ~ 99 Decimal system ID coding range, wherein toggle switch SW1 represents ID_ ten, and toggle switch SW2 represents ID_ position；

Step 2, the value for establishing each numerical digit of decimal system ID number represents the relational expression of numerical value with corresponding 4 toggle switch positions 1,2,3,4, It is specific as follows:

ID_ position=SW2 toggle switch fellow deputies' numerical value summation again divided by 10 remainder；

The summation of ID_ ten=SW1 toggle switch fellow deputies' numerical value again divided by 10 remainder；

Step 3, each toggle switch is electrically connected to 485 bus ID detection single-chip microcontroller, and by high-order area to the suitable of low level area Sequence carries out location layout from left to right and completes the design of 485 bus ID number reading programs.Such as Fig. 2, toggle switch SW1, SW2 are divided It is not electrically connected to the built-in pull-up function input pin PA1-PA8 of ID detection single-chip microcontroller U1, wherein single-chip microcontroller U1 is selected STM32F103C8T6, and location layout is carried out from left to right by the sequence of SW1-SW2, it is finally complete by the rule requirement of steps 1 and 2 It is designed at 485 bus ID number reading programs.

It so far, can be according to toggle switch SW1, SW2 when carrying out 485 bus ID encoding setting in installation The guide of bit identification character 1,2,3,4, and the switch for stirring those is determined by addition mental arithmetic within simple ten respectively To the position ON, to fast and accurately complete the encoding setting of wanted ID number, operated than binary mode encoding setting more intuitive With it is easy to use.For example the encoding setting that ID number is 45 operates are as follows: will represent position 4(or position 1 and the position of ten toggle switch SW1 3) position 1 and position 4(or position 2 and position 3 of a position toggle switch SW2 are represented and) position ON is pushed respectively.
