Brief description of the drawings
Fig. 1 is primary structure schematic diagram of the invention.
Fig. 2 is power carrier wireless signal sending module structural representation.
Fig. 3 demodulates schematic flow sheet for the signal of one embodiment of the invention.
Embodiment
Explanation is further explained to the present invention with specific embodiment below in conjunction with the accompanying drawings.
The present invention provides a kind of field Radio Network System, and it includes wireless signaling mechanisms 2；The wireless signaling mechanisms peace
On steel tower 1 loaded on power transmission network；The wireless signaling mechanisms include main controller and coupled wireless signal sending module,
Reception of wireless signals module.Primary structure schematic diagram is referring to Fig. 1.
In an embodiment of the present invention, wireless signal sending module and reception of wireless signals module include what is be sequentially connected
Power line signal coupling module, carrier modulation block, the data modulation module of band spectrum modulation module and multichannel carrier；The electric power
Line signal coupling module is coupled with the power line 3 of power transmission network.Primary structure schematic diagram is referring to Fig. 2.
Further, wireless signal sending module or reception of wireless signals module also include being connected on power line signal coupled mode
Filtration module between block, carrier modulation block.
Further, wireless signal sending module or reception of wireless signals module also include a power frequency being connected with main controller
Zero cross detection circuit.
When main controller detects power frequency zero cross signal, the pulse-modulated signal of predeterminated frequency is generated；Using the pulse
Modulated signal is modulated to primary carrier signal, so that the carrier signal after modulation is coupled to high pressure power frequency by signal coupling circuit
Power line；The carrier signal after modulation is demodulated in the power frequency zero cross signal corresponding same power frequency zero crossing, its
In, the carrier signal after the modulation is coupled by the signal coupling circuit from the high pressure power frequency electric line of force to be obtained.
The present invention uses the carrier signal of predeterminated frequency, because the carrier signal of predeterminated frequency can be less than prior art
In hundreds of KHzs carrier signal, and carrier signal is modulated in power frequency zero crossing, with coupled to high pressure power frequency electric
In the line of force, so as to avoid the high pressure power frequency electric line of force caused by the frequency of carrier signal is high to the larger of carrier signal
Decay, while ensure that transmission range (being not less than 2 .5 kms) farther out, solves power carrier of the prior art and leads to
The technical problem that signal attenuation is big, reliability is low of letter.
In an embodiment of the present invention, the wireless signaling mechanisms also include an alarm module being connected with main controller.When
Alarmed during wireless signaling mechanisms failure by the alarm module, notify maintainer to be overhauled in time.
In an embodiment of the present invention, in addition to a waterproof case；The wireless signaling mechanisms are arranged on outside the waterproof
In shell.Prevent the wireless device from exposing to the weather, the service life of extension fixture.
In other embodiments of the present invention, the wireless signaling mechanisms also include the network interface being connected with main controller.By
The network interface accesses internet, to realize the Wireless Networking of mobile terminal.
Above is presently preferred embodiments of the present invention, all changes made according to technical solution of the present invention, produced function is made
During with scope without departing from technical solution of the present invention, protection scope of the present invention is belonged to.
