Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, there is provided a kind of by power line carrier PLC, key phase frequency displacement FSK, tri-kinds of communication modes of direct sequence spread spectrum DSSS are combined, solve in communication and easily to be blocked affected by electrical equipment interference and decay and building, thus solve low pressure power information and adopt concentrated part intelligent electric meter and can not gather back the user power utilization information acquisition systems based on three mould isomeries of Information Problems.
The technical solution of the utility model is: a kind of user power utilization information collecting devices based on three mould isomeries, including child node and host node, described child node and host node all include putting in power amplifier, coupling transformer, narrow-band FM, MCU and wireless special purpose chip, described MCU with power amplifier, narrow-band FM are put and wireless special purpose chip is connected, described coupling transformer with power amplifier, narrow-band FM are put and electric lines of force is connected, described child node is at least two.
Described wireless special purpose chip is FSK communication chip and DSSS communication chip, described wireless special purpose chip is connected with antenna, described antenna is arranged in housing, be additionally provided with in described housing in power amplifier, coupling transformer, narrow-band FM put, MCU and wireless special purpose chip.
The beneficial effects of the utility model are:
1, this utility model is by being combined power line carrier PLC, key phase frequency displacement FSK, tri-kinds of communication modes of direct sequence spread spectrum DSSS, solve in communication and easily to be blocked affected by electrical equipment interference and decay and building, thus solve low pressure power information and adopt concentrated part intelligent electric meter and can not gather back problem.
2, this utility model can effectively solve the drawback of present stage low-voltage collecting meter reading communication channel, respective communication channel is had complementary advantages, thus effectively solve the capacity of resisting disturbance of any communication channel, when a kind of communication channel is interfered, another channel then can be selected to carry out communication, when being interfered simultaneously then by each annoyance level, thus the channel selecting interference minimum communicates, the wireless frequency shift keying of micropower (FSK) communication pattern uses frequency hopping simultaneously, is greatly enhanced capacity of resisting disturbance.
3, this utility model solves low-voltage customer node is affected by distribution building environment and resident's electric energy meter installation site, it is interfered under single communication pattern and signal shielding impact, each child node effective communication distance is caused to differ, the problem that signal isolated island occurs.
Accompanying drawing illustrates:
Fig. 1 is the onsite application schematic diagram of user power utilization information collecting device based on three mould isomeries.
Fig. 2 is host node and or the internal electric connection block diagram of child node.
Detailed description of the invention:
Embodiment: see Fig. 1 and Fig. 2.
User power utilization information collecting devices based on three mould isomeries, including child node and host node, child node and host node all include putting in power amplifier, coupling transformer, narrow-band FM, MCU and wireless special purpose chip, MCU with power amplifier, narrow-band FM are put and wireless special purpose chip is connected, coupling transformer with power amplifier, narrow-band FM are put and electric lines of force is connected, child node is at least two.
Wireless special purpose chip is FSK communication chip and DSSS communication chip, and wireless special purpose chip is connected with antenna, and antenna is arranged in housing, be additionally provided with in housing in power amplifier, coupling transformer, narrow-band FM put, MCU and wireless special purpose chip.
During use: a, centered by host node, child node is auxiliary, using wireless for micropower frequency shift keying fsk communication mode as communication agent, builds high-speed communication backbone network, it is achieved the real-time Communication for Power between major part child node and between host node；
B, child node carry out packing process to the user power utilization information collected, when information is transmitted by child node, first the distance of self and neighbouring node is determined, and by the building distributional environment between own node and neighbouring node and resident's electric energy meter installation site situation, by suitable transmission means, collection information is transmitted；
