Description
Technical field
The present invention relates to a kind of distributed wireless supervisory control system headend equipment being formed by the wireless monitor node of multiple separation.
Background technology
The equipment of supervisory control system is made up of three parts conventionally: front end, terminal and transmission channel.Headend equipment mainly detects guarded region or object, and terminal equipment carries out data processing and ensures that with control, transmission channel headend equipment is connected with the signal of terminal equipment.Existing headend equipment form is more, and active front end comprises radio radar, laser radar, ultrasonic radar, infrared or laser-correlation device etc., and passive type front end comprises photodetector, vibrations cable etc.; The form of terminal equipment mainly contains: supervisory control comuter, monitor or television machine, DVR or hard disk matrix etc.; Transmission channel has cable, optical fiber, microwave, laser etc.
Wired headend equipment need to have special power supply and communication cable, and difficulty or installation cost, as steep cliff, are installed high in the region that is difficult to set up for circuit.The appearance of wireless monitor headend equipment has solved this problem, wireless monitor headend equipment is that Radio Transmission Technology is applied on monitoring frontend, it can be sent to Surveillance center by wireless telecommunications means in real time by the field data of different location, use the mode of generator or storage battery by front monitoring front-end, can not need power supply and communication cable completely, but wireless monitor headend equipment still needs timing to carry out energy resource supply.Existing monitoring frontend is because each equipment wants overlay area larger, because volumes are larger a bit, disguised poor, to easy destroyed guarded region, as monitoring environment complexity, the boundary line of long transmission distance, needs unsafe factors such as anti-lightning strike, overload, power-off, electromagnetic interference and artificial destruction, and headend equipment is difficult to continuously and effectively carry out area monitoring.The structural form of existing headend equipment adopts detector to concentrate in same device structure conventionally, and the information obtaining does not have the value of checking mutually, can only reduce false dismissal and false alarm rate by algorithm or with miscellaneous equipment information fusion.For radar or photodetector, due to the diversity of guarded region physical features, also often there is monitoring blind area.Wireless Network is ripe a special kind of skill gradually along with the development of technology of Internet of things in recent years, mote network technology (the Dust Networks that in wireless group technology, comparative maturity has bee dance technology (Zigbee) and Linear Techn Inc. to release at present
tM), these two kinds of technology be all can self-organizing network closely, the two-way wireless communication technology of low-power consumption, low cost, low data rate, low complex degree.
Summary of the invention
The present invention is directed to the weak point of prior art monitoring frontend, propose a kind ofly by collection of energy, monitoring, Wireless Network combination, be easy to install, disguised strong, resolution is high, non-blind area, communication link can self-healings distributed wireless monitoring frontend.
Above-mentioned purpose of the present invention can be achieved by following technical solution.A kind of distributed wireless monitoring frontend, comprise the distributed wireless monitor node of multiple separation, each distributed wireless monitor node is made up of collection of energy module, power module, monitoring module, wireless networking module and sealing shell, power module is monitoring module and wireless networking module for power supply, it is characterized in that: collection of energy module is charged the natural energy converting electrical energy of collecting from external environment to power module; Power supply dormancy and the timing wake-up of the whole wireless monitor node of main control chip Timer Controlling in wireless networking module; Wireless networking module main control chip distributes according to the node of neighborhood, adopts one of star-network topology, tree network topology and three kinds of patterns of mesh network topologies to carry out the control of wireless network process of self-organization; Monitoring module wireless networking module is carried out signal and communication, when monitoring module is in the time that guarded region detects interested information, and the enable signal that main control chip is launched the notification signal of the monitoring module receiving as alarm signal; Alarm signal is transferred to trunking or monitor terminal by wireless self-organization network, or carries out being transferred to monitor terminal by wireless self-organization network again after warning information confirmation with periphery wireless monitor node.
The present invention has following beneficial effect than prior art:
The present invention connects collection of energy module, power module, monitoring module with wireless networking module, be encapsulated in and form a wireless monitor node in sealing shell, the wireless communication networks self-organizing of the wireless monitor node by multiple separation forms distributed wireless watch-dog.The wireless monitor node that multiple separation are installed at guarded region forms distributed wireless monitor headend equipment, adopt collection luminous energy, heat energy or mechanical energy natural energy converting electrical energy to charge to power module, power module provides electric energy for monitoring module and wireless networking module, the energy that each wireless monitor node is collected by collection of energy module carries out work, need not set up power cable, be easy to install.The wireless communication networks that each node can consist of node and terminal called, this distributed node Wireless Network can complete with ripe Zigbee-technology.Because generally all distributed nodes can not carry out communication with terminal simultaneously, only, in having warning information to occur, just can send warning to terminal, the monitoring module of multiple separation completes the monitoring to a region jointly.
The present invention adopts and wakes control up in wireless networking module, by its power supply dormancy and the timing wake-up of the whole wireless monitor node of main control chip Timer Controlling, make the only work in the time waking up of whole wireless monitor node, all the other time dormancy are energy-conservation, solve front monitoring front-end and used generator or storage battery power supply equipment complexity, useful life is short, easily causes the problem of power supply disappearance.
The monitoring module of wireless monitor node of the present invention and wireless networking module can adopt SOC (system on a chip) solution, accomplish miniaturization, low-power consumption.Therefore collection of energy module and power module also can corresponding miniaturizations, thereby the volume of each wireless monitor node can be significantly less than existing front monitoring front-end, has stronger disguise, is difficult for being found and destroying.
Wireless monitor nodal distance guarded region of the present invention is nearer than existing radar, photoelectric monitoring front end, stronger to the information of interest resolving power of guarded region.In the time that wireless monitor node distribution density is enough, can accomplish the non-blind area monitoring to guarded region.
Of the present invention aspect communication link, can adopt mesh network topologies pattern time, between node, be the communication of equity completely, all nodes all have the ability of selecting that re-routes, communication path is not unique, has very strong communication network self-healing property, in the time that some node is not worked, all the other node reorganizable communication links, ensure that communication is normal.
