The specific embodiment
This utility model is in order to improve in the existing armarium, also needs a lot of holding wires between a lot of parts except power line and causes connecting between the parts complicated defective.For above-mentioned purpose, information in this utility model between the parts is transmitted in and has adopted PLC(Power Line Carrier on the Physical layer) technology, namely carry out carrier communication by electric lines of force, the PLC technology is with the OFDM modulation technique data to be modulated, transmit at electric lines of force then, at receiving terminal, through filtering mode modulation signal is leached earlier, through reconciling, just can obtain former signal of communication again; Adopt the IEEE802.15.4 agreement in data link layer, IEEE802.15.4 has described Physical layer and the media access control protocol of low rate wireless personal local area network.By said method power line and order wire are combined, made things convenient for the system building in the armarium, expansion and plant maintenance.
Fig. 2 is the connection diagram of power line and the order wire of each parts in the armarium of the present utility model.As shown in Figure 2, comprise in the armarium of the present utility model for the power supply communication bus 10 that transmits power supply and signal of communication; By power supply communication bus 10, provide the electric power source distribution device 20 of power supply to panel 35 and other end-equipments; Insert in power supply communication bus 10, for the panel 35 of controlling end-equipment; And insert in power supply communication bus 10, under the control of control panel 35, carry out the end-equipment 31 of corresponding operating.Above-mentioned end equipment 31 and panel 35 interconnect by power supply communication bus 10, and all has the power line communication module of the signal that sends and receive by power supply communication bus 10 being carried out coding/decoding, when sending and receive signal, send and receive signal according to the address (address interconnect is inequality) of the master chip of panel 35 and end-equipment 31.
Fig. 3 is the structural representation of end-equipment 31 in the armarium of the present utility model.As shown in Figure 3, end-equipment 31 comprises, to receiving by power supply communication bus 10 that the signal that sends carries out the power line communication module 33 of encoding and decoding and also comprising beyond the end-equipment 31 of executable operations under the control of panel 35 fixed-voltage power supply that provides by power supply communication bus 10 is transferred to the builtin voltage change-over circuit 32 that is suitable for end-equipment 31 voltages.End-equipment 31 and panel 35 are to be connected in series, and therefore the voltage that receives all is identical, but according to different end-equipment 31, needed reception voltage also can be different, and part end-equipment 31 needs built-in builtin voltage change-over circuit 32 for this reason.Panel 35 also can increase voltage conversion circuit as required.
Fig. 4 is another structural representation of end-equipment 31 in the armarium of the present utility model.As shown in Figure 4, end-equipment 31 comprises, to receive the power line communication module that the signal that sends carries out encoding and decoding by power supply communication bus 10; The master chip loop of executable operations under the control of panel 35: the fixed-voltage power supply that provides by power supply communication bus 10 is transferred to the builtin voltage change-over circuit 32 that is suitable for end-equipment 31 voltages; And be arranged on the front end of builtin voltage change-over circuit 32, be used for eliminating the wave filter 34 of the electromagnetic interference that the high electrical power on the power supply communication bus produces.
Above-mentioned armarium can be the CT imaging device, wherein end-equipment 31 comprises and is arranged on CT frame front, rear, left and right, be used for to show the front, rear, left and right display floater of sick bed and shelf position state and be arranged in the CT frame imaging passage, be used for the respiratory navigator of breathing navigating, and be used for controlling the control box of sick bed and shelf position.
Above-mentioned armarium can be the MR imaging device, wherein end-equipment 31 comprises and is arranged on MR frame front, rear, left and right, be used for to show the front, rear, left and right display floater of sick bed and shelf position state and be arranged in the MR frame imaging passage, be used for the respiratory navigator of breathing navigating, and be used for controlling the control box of sick bed and shelf position.
In above-mentioned CT imaging device or MR imaging device, the power supply order wire can produce high electrical power in order to transmit power supply and signal of communication, the electromagnetic interference that these high electrical power cause can influence the imaging effect of CT and MR imaging device, power supply communication bus 10 in this utility model and power supply communication bus 10 carry out multiple twin shielding design with the connecting line of each end-equipment 31 for this reason, and the wave filter 34 of an elimination electromagnetic interference is set before the builtin voltage change-over circuit 32 of each end-equipment 31.Twisted-pair feeder is to form by the plain conductor of a pair of mutually insulated is stranded, adopts this mode, not only can resist the Electromagnetic Interference that a part comes from the outside, and can reduce the external interference of self signal.Two copper conductors that thoroughly do away with edge are twisted together mutually by certain density, and the electric wave of lead radiation in transmission can be offset by the electric wave that other single line sends.The name of " twisted-pair feeder " also is to come therefrom.
Twisted-pair feeder can be divided into Shielded Twisted Pair (Shielded Twisted Pair, STP) with unshielded twisted pair (Unshielded Twisted Pair, UTP), so-called Shielded Twisted Pair just refers to have between twisted-pair feeder and outer layer insulation big envelope a metal level to cover layer.Screen layer can reduce radiation, prevents that information from being eavesdropped, and also can stop entering of external electromagnetic interference, makes Shielded Twisted Pair have higher transfer rate than similar unshielded twisted pair.
Optimize the Control on Communication between a plurality of parts in the armarium with the power line communication plan among the design, the power line communication reliability is very high, and utilizes existing power line as the communication physical link, has saved the system signal cable, optimize system structure, improved the extensibility of system.Owing to have signal communication on the power line, cause power-supply fluctuation inevitably, therefore at the frequecy characteristic of telecommunication circuit, need suitably optimize the filter circuit of power module, realize that system stability powers reliably.
Though this utility model discloses as above with preferred embodiment; so it is not in order to limit this utility model; any those skilled in the art; in not breaking away from spirit and scope of the present utility model; when doing a little modification and perfect, therefore protection domain of the present utility model is worked as with being as the criterion that claims were defined.
