The advantage using multi-channel serial port coordination multiplexing method is the most obvious.
Accompanying drawing explanation
Fig. 1 is that the multi-channel serial port that Itellectualized uptown power information gathers coordinates multiplexing method particular flow sheet；
Fig. 2 is the Itellectualized uptown power information acquisition system configuration diagram that application multi-channel serial port coordinates multiplexing method.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following example are descriptive
, it not determinate, it is impossible to limit protection scope of the present invention with this.
The multi-channel serial port that a kind of Itellectualized uptown power information gathers coordinates multiplexing method, the breath acquisition system of application this method
Including Itellectualized uptown power information acquisition system main website, acquisition terminal, decoder and measuring equipment, Itellectualized uptown power information
Hereinafter referred to as main website of acquisition system main website, main website connects multiple acquisition terminals, and each acquisition terminal is all connected with multiple decoder, often
Individual decoder connects a measuring equipment；
Operating procedure is as follows:
(1) carry out the division of Itellectualized uptown according to acquisition terminal distribution in garden, garden is carried out subregion and numbers, each
Subregion is furnished with an acquisition terminal；Garden is divided into N number of subregion, and numbering is respectively C1To CN；
(2) the measuring equipment of each subregion is grouped, often assembles and put a communication serial port and multidigit binary logic is translated
Code device, and, set up decoder input, output and the corresponding relation between different numbering measuring equipments；
(3) acquisition is assigned by main website；
(4) after the acquisition terminal of each subregion receives the order that main website is assigned, forward acquisition separately down, gather
Order the input according to decoder, output to be automatically switched from the corresponding relation of different numbering measuring equipments, use logical successively
Letter serial ports；
The most selected measuring equipment uses communication serial port, receives the order that acquisition terminal forwards, carries out information gathering, so
After upload required collection information to acquisition terminal again；
(6) the acquisition terminal of each subregion receives the collection information choosing measuring equipment to upload by communication serial port；
(7) main website receives collection information, and main website receives the collection information uploaded from each acquisition terminal.
Such as:
Measuring equipment in each subregion is divided into m group, every component join 2aIndividual measuring equipment, numbering is respectively 1 to 2a, one
In group, all of measuring equipment shares a communication serial port, the most each zone configuration m communication serial port.Additionally at each serial ports
A upper additional a position binary logic decoder, it is possible to 0 to 2 can be realizedaThe conversion of-1.Jn,m-bRepresent the n-th subregion m
The measuring equipment of numbered b in group.All measuring equipments of the n-th subregion can be expressed as follows:
In formula, n=1,2 ... N, for partition number；M=1,2 ..., for group number；m·2a≤Jn,maxRepresent that a zone metering sets
Standby total number is not to be exceeded the accessible maximum J of this subregion acquisition terminaln,max。
The power information acquisition system main website of Itellectualized uptown issues collection message command to the n-th all measuring equipments of subregion
After, often organize a position binary logic decoder additional on serial ports in this subregion and proceed by decoding according to input, after output adds 1
The measuring equipment numbering that correspondence is chosen, concurrently sets automatic switchover time interval Δ T, automatically carries out the measuring equipment of different numbering
Between switching, detailed process is as follows:
The input of a bit decoder is initially set toIt is output as 0, then chooses in this subregion in respective group numbered 1
Measuring equipment, i.e. Jn,1-1,Jn,2-1,…,Jn,m-1Use and each organize unique communication serial port, complete to refer within the time set
The acceptance made and the loopback that breath need to be accepted and believed；
After Δ T, the input of a bit decoder automatically becomesIt is output as 1, then in choosing this subregion in respective group
The measuring equipment of numbered 2, i.e. Jn,1-2,Jn,2-2,…,Jn,m-2Use and each organize unique communication serial port, in the time set
Inside complete the acceptance of instruction and the loopback of breath need to be accepted and believed；
By that analogy, through (2a-1), after Δ T, the input of a bit decoder becomesTime, it is output as 2a-1, then choose
In this subregion in respective group numbered 2aMeasuring equipment, i.e.Use each group unique logical
Letter serial ports, completes the acceptance of instruction and need to accept and believe the loopback of breath, so far, completing to the n-th all measuring equipments of subregion
Secondary information gathering.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, but those skilled in the art can managing
Solving: without departing from the spirit and scope of the present invention, various replacements, to change and modifications be all possible, therefore, and the model of the present invention
Enclose and be not limited to embodiment and accompanying drawing disclosure of that.
