Abstract
This invention discloses the method of communication with position codes and the apparatus thereof. They belong to the technical field of processing and transmitting the data and signals in electrical systems. In the transmitting system the positios at which the signals of the transmitting and the receiving components are generated represent the address signals, the levels of the pulses of these signals represent the digital signals of these signals, and respective components can be connected through a communication line. Using the communication method of the digital pulse converting type, the connection between the transmitting and the receiving components in the transmitting system can be changed to the connection with one line, thereby the base pins of various components and the connecting lines between various equipments can be reduced.
Description
Technical field:
The present invention relates to a kind of new means of communication, especially a kind of position code means of communication and device are provided, belong to electrical system data processing technology field.
Background technology:
Along with development of computer, the production difficulty of computer chip turns to drawing of pin by the semiconductor machining in past, and the line of each chip has too much limited the development of computer greatly.Particularly the application of technology of serial communication has then limited the speed of communication in the computer radio communication, and at present, the stationary problem of many computer communications has become urgent problem.
Summary of the invention:
The invention provides a kind of position code means of communication (hereinafter to be referred as the WZ sign indicating number), solved in the transmission system that communication connects challenge between the signalling component and receiving element, promote that modern communications technology turns to three-dimensional development by the plane.
Solution of the present invention is as follows: address signal is represented in the position that the signal of signalling component and receiving element produces in transmission system, and the height of signal pulse is represented the digital signal of this signal, can connect by a communication line between each element.
Send the different pulse signals different with the position of pulse voltage in signalling component, according to actual needs, the address signal of each element can be one or a plurality of, and when being a plurality of, each address signal is being represented the weighted signal of this element signal again.
As shown in Figure 3, be the oscillogram of WZ position code communication, t axle wherein is time shaft both, represent the relative position of each pulsion phase for the ceiling voltage synchronizing signal, address signal just, and the voltage height of voltage axis pulse just, designate data signal.Pulse height is divided into 10 grades here, is representing numeral 0,1,2,3,4,5,6,7,8,9, greater than 10 o'clock, we can select two pulses to finish the transmission of same data in the needs data.The numeral of wherein previous pulse representative is 10 * (0,1,2,3,4,5,6,7,8,9), specifically as shown in the figure.
In transmission system, comprise signalling component and receiving element, each element internal is set up two circuit: one is digital commutation pulse circuit, target chip selection signal and digital signal be treated to differing heights together and have the signal pulse of fixed position, the fixed position determines the reception object of these data, and pulse height is then represented number; One is the digital circuit of pulses switch, converts number to be exported to pulse signal output, and the data/address bus of above-mentioned each circuit is connected by a lead with address bus.
Good effect of the present invention is: adopt the digital change type means of communication of pulse, the contact between signalling component in transmission system and the receiving element can be become single line and connect, thereby reduce the pin of each element and the connecting line between each equipment.Can save a large amount of on-load switches and transfer wire, the simplified apparatus structure, the reduction equipment volume reduces production costs, and operates more simple and convenient.Can be widely used in automobile, electric control system,

Embodiment:
Embodiment 1
According to Fig. 1, signalling component and receiving element in transmission system, as the CPU in the computer system, EPROM, ROM and each interface circuit, each element internal is set up two circuit: one is digital commutation pulse module, target chip selection signal and digital signal be treated to differing heights together and have the signal pulse of fixed position, the fixed position determines the reception object of these data, and pulse height is then represented number; One is the digital circuit of pulses switch, converts number to be exported to pulse signal output, and the data/address bus of above-mentioned each circuit is connected by a lead with address bus.
Embodiment 2
There was a large amount of connecting lines in the PLC controller in the control circuit of 10 station lathes in the past, and its weight reaches 1.5 tons more than, and the I﹠M difficulty is also big especially.
Adopt after the WZ position code control technology of the present invention, its connecting line has only one, and concrete schematic diagram is as follows:
With reference to Fig. 2, each main order a module that number is converted to the WZ sign indicating number has been installed on the element K, the digital signal of each K switch representative is converted into the position code signal, and the position code signal that each K transforms out is different with respect to the synchronizing signal position of whole system, so just all signals is all focused on the holding wire J01.This root holding wire is connected with the WZ sign indicating number revolution sign indicating number module that adds on the PLC main frame, and the WZ coded signal is converted into digital signal, directly carries out communication with main PLC.And the execution signal that main PLC sends joins through the number commentaries on classics WZ sign indicating number module that installs additional on the PLC, and the digital signal that PLC is sent is converted into the WZ coded signal, delivers on the J01 bus.A WZ sign indicating number revolution sign indicating number module is housed again on each executive component, the WZ coded signal on the J01 line is converted into digital signal, thereby drives each executive component, carry out corresponding action.
Through after the above change, all reduced connecting line in a large number for all industrial equipments, reduced installation difficulty and failure rate.
