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 the stationary object, present solution mainly contains following two kinds: 1) many slip rings ejector: each holding wire all need independently slip ring be corresponding with one in this structure; Signal between rotating object and stationary object needs a large amount of slip ring and brush more for a long time, causes that whole apparatus structure is complicated, big, the reliability of taking up room reduces.2) radio transmitting device: adopt radio frequency, bluetooth, wireless transmitting and receiving device such as infrared, avoided mechanical structures such as slip ring.But this installation cost is high, is not suitable for bad working environment, has characteristics such as high-intensity magnetic field (reaching several kilogauss), intense radiation, high centrifugal force (reaching hundreds of Mpa), high temperature (reaching 100 deg.c), strong vibration such as high speed rotor of motor.
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 the stationary object, proposed a kind of single slip ring multichannel rotor signal transmitting apparatus, more reasonable structure is with simple, and cost is low.
Technical scheme of the present invention is: a kind of single slip ring multichannel rotor signal transmitting apparatus; K * n the slip ring that conductor piece is alternate with the non-conductor sheet arranged; Slip ring is fixed on the rotor; K * n conductor piece connects with epitrochanterian k * n holding wire respectively, and wherein n is a port number, and k is the signal way of single passage; K conductor piece of n group on the slip ring is along with the rotor rotation contacts with k brush successively; K brush is fixed on the stationary apparatus, is connected with an external k holding wire, and k holding wire is with the data feed signals processing unit that receives, and signal processing apparatus carries out the smoothing processing of data, realizes the multi channel signals transmission.
Said non-conductor sheet comprises isolates non-conductor sheet and framing signal non-conductor sheet, isolates the non-conductor sheet and places between the conductor of each passage, and framing signal non-conductor sheet places between passage and the passage, and framing signal non-conductor sheet is different with 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, and only need a slip ring can realize the multi channel signals transmission, have advantage simple in structure, compact, that cost is low; Compare radio transmitting device, on the rotating object undesired signal emitter etc. be subject to disturb, flimsy electrical type device, reliability is high, be more suitable for abominable relatively environment for use.
Description of drawings
Fig. 1 is a 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 the non-conductor sheet; Be fixed on the rotor; K * n conductor piece connects with epitrochanterian k * n holding wire respectively, and wherein n is a port number, and k is the needed signal way of single passage; K brush is fixed on the stationary apparatus, is connected with an external k holding wire, single signal transmission that realizes single passage constantly; 1 cover signal processing apparatus is a k * n signal with the reduction of data that receives in k the holding wire, the smoothing processing of the line data of going forward side by side, thus realize the multi channel signals transmission.
Be transmitted as example with the Generator Rotor Temperature signal, the function of this device is described.Need on the generator amature to suppose n temperature test point; Therefore need bury n pt100 temperature sensor (adopting three-wire system to connect) underground; Wherein each temperature sensor has k pin (k=3 here); Then rotor need draw altogether k * n root holding wire and respectively with slip ring in k * n conductor piece be connected, be used to send the temperature information of n paths.K each position of brush only connects with k pin of 1 temperature sensor, the signal of 1 temperature test point of transmission, and then rotor whenever rotates a circle, and then accomplishes the collection to n temperature test point.K the data process signal processing apparatus that brush is drawn realized the reproduction of n paths signal.For identification n road signal, have the conductor piece structure alternate on the slip ring, and have a data zero clearing structure dexterously with the non-conductor sheet, thereby accurately " tell " the current reception of signal processor be the signal of which temperature sensor.Because rotor speed has tens revolutions per seconds rotating speed usually, so can carry out tens times data acquisition to single temperature test point each second, for variations such as temperature, pressure comparatively slowly signal satisfy accuracy requirement fully.
Be transmitted as example with temperature signal, introduce the principle of single slip ring multichannel rotor signal transmitting apparatus.Schematic diagram as shown in Figure 1 supposes that rotor has 3 temperature test points (port number is 3, representes with 1,2,3 respectively); Select for use pt100 as temperature sensor 10,11,12; Adopt three-wire system to connect method, each transducer needs 3 lead-in wires, and each passage is 3 the tunnel; Represent with a, b, c that respectively for example the 1st passage has 1a, 1b, 1c totally 3 tunnel.
The inner A of dotted line is a moving component, follows the rotor rotation, 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 the slip ring straight line launched, 1,2,3 channel signal sheets spatially evenly distributed, like figure the 1st channel signal sheet by conductor piece 14; The centre is separated by non-conductor 13 materials; In order to pick out the triple channel signal, also need framing signal sheet 14 between the triple channel signal, the non-conductor sheet 14 of therefore locating usefulness is different with non-conductor sheet 13 width with isolation.
Suppose the rotor rotation, temperature sensor begins to transmit data, and transducer 10,11,12 transmits [1a, 1b respectively; 1c], [2a, 2b, 2c], [3a, 3b; 3c], change slowly and under the motor speed condition with higher at signal, can think constant at the rotor signal that rotates a circle.In signal processor, set, when brush contacted with non-conductor sheet 13, signal was [0,0,0], and when contacting with insulated conductor sheet 14, signal is [00,00,00], and then brush will contact with the 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 then the data of signal processor reception are [2a, 2b, 2c; 0,0,0; 3a, 3b, 3c; 00,00,00; 1a, 1b, 1c; 0,0,0], because 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].
