Five, embodiment
Below in conjunction with drawings and Examples, further specify structure and characteristics based on the on-site control device of wireless sensor network, in the accompanying drawing:
As Fig. 1, a kind of on-site control device 1 of the utility model based on wireless sensor network, comprise antenna 2, pilot lamp 31, pilot lamp 32, power interface 4, switch 5,8 road signals input isolation processing unit interface 61, interface 62, interface 63, interface 64, interface 65, interface 67, interface 68,8 tunnel Signal Spacing control output unit interface 71, interface 72, interface 73, interface 74, interface 75, interface 76, interface 77, interface 78, common ground interface 91, common ground interface 92.During use the switching value signal that is used to control is received any one that 8 road signals are imported the isolation processing unit interface, simultaneously controlled cell is received an interface of the correspondence of 8 tunnel Signal Spacing control output unit interface, common ground is connected by common ground interface 91, common ground interface 92; After above finishing, by power interface 4 energized, pilot lamp 31 can dodge ruddiness always under the situation of operate as normal, in operate as normal, opens switch 5 with the expression power supply, and pilot lamp 32 can dodge green glow always, is in normal operating conditions with display device; Under the normal operating conditions, antenna 2 can be monitored the also feedback signal of receiving slave unit always.
As shown in Figure 2, in embodiment one of the present utility model, on-site control device based on wireless sensor network, comprise wireless singlechip unit 10, based on radiofrequency signal processing unit 11, RS232 communications interface unit 12, the 8 way switch amount input blocks 13 of highly integrated 2.4G common frequency band, 8 way switch amount output units 14, DC--DC circuit unit 15, antenna element 16, photoelectricity isolated location 21 and photoelectricity isolated location Unit 22.Wireless singlechip unit 10 is the core of this device, and wherein 8 way switch amount input blocks 13 couple with wireless singlechip 10 after being connected with photoelectricity isolated location 21 again; 8 way switch amount output modules 14 connect good coupling with wireless singlechip more afterwards with photoelectric isolation module 22; Radiofrequency signal processing unit 11 is coupled to wireless singlechip unit 10, external antenna unit 16, and it mainly is that the signal of the antenna element 16 that receives is modulated, and the signal of wireless singlechip unit 10 is carried out demodulation; RS232 communications interface unit 12 directly is coupled to wireless singlechip unit 10, and DC--DC circuit unit 15 adopts the two-way output interface, and the voltage of 6--36V is provided to system.
Shown in Figure 3, in embodiment one of the present utility model, based on the on-site control device of wireless sensor network, 10 node apparatus networkings are example explanation networking plan, and third party's gateway device of this programme configuration is convenient to this wireless sensor network is inserted public network.Each node apparatus is set up static shortest path (because the control information flow is little, therefore selecting static routing) by broadcast type route discovery algorithm and Dijikstra algorithm and is generated the routing table of node apparatus separately.With node apparatus 36 is the transmission feature of example explanation control information flow.Master Control Center is to node apparatus 36 transmitting control commands, this order at first arrives node apparatus 37, resolve the control information frame, node apparatus is just directly transmitted this frame, adjacent node device 32,33,310,36 is received this control information frame simultaneously, node apparatus 32,33,310,36 inquiries routing table separately has only node apparatus 36 to resolve and carry out the order of this control information.Node apparatus 32,33,310 finds that through table of query and routing node apparatus 36 all is their adjacent node, therefore no longer transmits this control information frame.The quantity of state information of the field apparatus of gathering for node apparatus, the thinking that is transferred to Master Control Center is fully the same with the transfer mode of control information.
