Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the wireless multi-party communication system of nuclear power plant of the present invention is described in detail, wherein:
Fig. 1 is the schematic diagram of the wireless multi-party communication system of nuclear power plant of the present invention.
Embodiment
In order to make goal of the invention of the present invention, technical scheme and technique effect thereof more clear, below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.Should be understood that, the embodiment described in this specification is only used to explain the present invention, is not intended to limit the present invention.
Nuclear power plant's multi-party communication system as shown in Figure 1, comprise multiple base station 10, this base station 10 each comprises multiple intermediate station 100, each intermediate station 100 is placed on the center needing quorum sensing inhibitor respectively, and this intermediate station 100 comprises receiving system 1004, emitter 1002 and control device 1006.
Multiple intermediate stations 100 in same base station 10 pass through LAN Monitoring System.
Because this acc power of intercom is about about 4W, straight-through close together.And because nuclear power plant is inner with a varied topography and shielding is serious, therefore intercom power cannot penetrate screen, and its diffracting power is limited.Therefore, this receiving system 1004 can be utilized to receive the calling of intercom; And automatically forward this call signal by this emitter 1002, i.e. communication request signal.
Here to illustrate a bit, here the call signal of indication be exactly hereinafter described communication request signal not as restriction concrete example.Therefore, this receiving system 1004 is for received communication request signal; This communication request signal comprises communications destination coordinate.Here the communications destination coordinate of indication, refers to the coordinate address of this communication request signal for calling terminal place.And this emitter 1002 is by the control of this control device 1006, forward this call signal.
Wherein, this intermediate station 100 also comprises judgment means 1008, and this judgment means 1008 is for judging the position of this communications destination coordinate:
If this communications destination coordinate and this communication request signal send position in same intermediate station 100 coverage, then this emitter 1002 forwards this communication request signal to this communications destination coordinate.
If the coverage sending the different intermediate stations 100 of position respectively in same base station 10 of this communications destination coordinate and this communication request signal, then this communication request signal is forwarded to the intermediate station 100 at this communications destination coordinate place via this local area network (LAN), then is forwarded to this communications destination coordinate by the emitter 1002 of the intermediate station 100 at this communications destination coordinate place.
If this communications destination coordinate and this communication request signal send position respectively in the coverage of different base station 10, then this communication request signal is forwarded to the base station 10 at this communication request signal place via this local area network (LAN), and the base station 10 at this communications destination coordinate place is forwarded to by the base station 10 at this communication request signal place, this communication request signal is forwarded to the intermediate station 100 at communications destination coordinate place by the base station 10 at this communications destination coordinate place by local area network (LAN), by this emitter 1002 of the intermediate station 100 at this communications destination coordinate place, this communication request signal is forwarded to this communications destination coordinate again.
In one embodiment, this receiving system 1002 comprises one or more reception antenna.As mentioned above, intermediate station is placed on the center needing quorum sensing inhibitor, if this intermediate station needs the region of covering larger, even if during two intercom intercommunications then in same intermediate station coverage, owing to having 4W in this acc power of intercom, therefore, same needs receives this communication request signal via the reception antenna nearest from this intercom.Otherwise, if only have a reception antenna, and itself and intercom apart from too far away, then because this acc power of intercom is too little, or barrier shielding, then this reception antenna cannot receive communication request signal.
In one embodiment, this emitter 1002 comprises one or more transmitting antenna.Similarly, need the size according to intermediate station overlay area and concrete structure, configure one or more transmitting antenna.
