Technical field
The present invention relates to a kind of signal transmission technology, particularly a kind of single slip ring multichannel rotor signal transmitting apparatus.
Background technology
For the multi channel signals transmission problem between rotating object and stationary object, current solution mainly contains following two kinds: 1) many slip rings ejector: in this structure, each holding wire needs that independently slip ring is corresponding with one; When the signal between rotating object and stationary object is more, need a large amount of slip ring and brush, cause that whole apparatus structure is complicated, large, the reliability of taking up room reduces.2) radio transmitting device: adopt radio frequency, bluetooth, the wireless transmitting and receiving device such as infrared, avoided the mechanical structures such as slip ring.But this installation cost is high, be not suitable for severe operational environment, such as high speed rotor of motor, there is the features such as high-intensity magnetic field (reaching several kilogauss), intense radiation, high centrifugal force (reaching hundreds of Mpa), high temperature (reaching 100 degrees Celsius of left and right), strong vibration.
Summary of the invention
The present invention be directed to multi channel signals transmitting device complex structure, the high problem of cost between present rotating object and stationary object, proposed a kind of single slip ring multichannel rotor signal transmitting apparatus, more reasonable structure and simple, cost is low.
Technical scheme of the present invention is: a kind of single slip ring multichannel rotor signal transmitting apparatus, there is k * n the slip ring that conductor piece is alternate with non-conductor sheet, slip ring is fixed on rotor, k * n conductor piece connects with epitrochanterian k * n holding wire respectively, wherein n is port number, the signal way that k is single passage; K conductor piece of n group on slip ring is along with rotor is successively with k brush contact; K brush is fixed on stationary apparatus, is connected with an external k holding wire, and k holding wire send signal processing apparatus by the data of reception, and signal processing apparatus carries out the smoothing processing of data, realizes multi channel signals transmission.
Described non-conductor sheet comprises isolation non-conductor sheet and framing signal non-conductor sheet, and isolation non-conductor sheet is placed between the conductor of each passage, and framing signal non-conductor sheet is placed between passage and passage, and framing signal non-conductor sheet is different from isolation non-conductor sheet width.
Beneficial effect of the present invention is: single slip ring multichannel rotor signal transmitting apparatus of the present invention, compare many slip rings ejector, only need a slip ring can realize multi channel signals transmission, have advantages of simple in structure, compact, cost is low; Compare radio transmitting device, on rotating object undesired signal emitter etc. be easily disturbed, flimsy electrical type device, reliability is high, be more suitable for relatively severe environment for use.
Accompanying drawing explanation
Fig. 1 is single slip ring multichannel rotor signal transmitting apparatus schematic diagram of the present invention.
Embodiment
A kind of single slip ring multichannel rotor signal transmitting apparatus comprises: 1 has k * n the slip ring that conductor piece is alternate with non-conductor sheet, be fixed on rotor, k * n conductor piece connects with epitrochanterian k * n holding wire respectively, and wherein n is port number, and k is the needed signal way of single passage; K brush, is fixed on stationary apparatus, is connected with an external k holding wire, single signal transmission that realizes single passage constantly; 1 cover signal processing apparatus, is reduced to k * n signal by the data that receive in k holding wire, and carries out the smoothing processing of data, thereby realizes multi channel signals transmission.
With Generator Rotor Temperature signal, be transmitted as example, the function of this device is described.Suppose to need on generator amature n temperature test point, therefore need to bury n pt100 temperature sensor (adopting three-wire system to connect) underground, wherein each temperature sensor has k pin (k=3 herein), rotor need to be drawn altogether k * n root holding wire and is connected with k * n conductor piece in slip ring respectively, for sending the temperature information of n paths.K each position of brush only connects with k pin of 1 temperature sensor, transmits the signal of 1 temperature test point, and rotor often rotates a circle, and completes the collection to n temperature test point.K the data process signal processing apparatus that brush is drawn, realizes the reproduction of n paths signal.For identification n road signal, on slip ring, there is the structure that conductor piece is alternate with non-conductor sheet, and there is a data zero clearing structure dexterously, thereby accurately " tell " the current reception of signal processor be the signal of which temperature sensor.Because rotor speed has the rotating speed of tens revolutions per seconds conventionally, so can carry out the data acquisition of tens times to single temperature test point each second, for the variations such as temperature, pressure comparatively slowly signal meet accuracy requirement completely.
With temperature signal, be transmitted as example, introduce the principle of single slip ring multichannel rotor signal transmitting apparatus.Schematic diagram as shown in Figure 1, (port number is 3 to suppose there are 3 temperature test points by rotor, with 1,2,3, represent respectively), select pt100 as temperature sensor 10,11,12, adopt three-wire system connection, each transducer needs 3 lead-in wires, and each passage is 3 tunnels, with a, b, c, represent respectively, for example the 1st passage has 1a, 1b, 1c totally 3 tunnels.
The inner A of dotted line is moving component, follows rotor, comprises transducer, lead-in wire, slip ring.Non-moving component comprises brush, lead-in wire, signal processor B.
The key of apparatus of the present invention is the design of slip ring, after slip ring straight line is launched, 1,2,3 channel signal sheets are spatially uniformly distributed, if figure the 1st channel signal sheet is by conductor piece 14, centre is separated by non-conductor 13 materials, in order to pick out triple channel signal, between triple channel signal, also need framing signal sheet 14, the non-conductor sheet 14 of therefore locating use is different with non-conductor sheet 13 width from isolation.
Suppose rotor, temperature sensor starts to transmit data, and transducer 10,11,12 transmits respectively [1a, 1b, 1c], [2a, 2b, 2c], [3a, 3b, 3c], at signal intensity, slowly and motor speed is higher in the situation that, can think constant at one week signal of rotor.In signal processor, set, when brush contacts with non-conductor sheet 13, signal is [0,0,0], and while contacting with insulated conductor sheet 14, signal is [00,00,00], and brush will contact with non-conductor sheet with conductor piece successively.In order to have more generality, we are placed on the initial position of brush on the conductor piece of transducer 11 correspondences, and the data that signal processor receives are [2a, 2b, 2c; 0,0,0; 3a, 3b, 3c; 00,00,00; 1a, 1b, 1c; 0,0,0],, due to the existence of framing signal and isolation signals, the signal that signal processor is easy to pick out transducer 10,11,12 is respectively [1a, 1b, 1c], [2a, 2b, 2c], [3a, 3b, 3c].
