Below in conjunction with accompanying drawing, technical solution of the present invention is further described.
The present invention includes several monitoring terminals, terminal management main frame and worm monitoring data center.As shown in Figure 1, several monitoring terminals, terminal management main frame form field sensor network, by existing the Internet and/or cell phone network, link with worm monitoring data center.Worm monitoring Monitoring Data center main will be responsible for the telemanagement of each field sensor network, and carries out data and gather and analyze.Yi Ge data center can manage a plurality of fields sensor network, and to realize, multistage monitoring network is set up, Data classification collection gathers and analytical applications; Field sensor network is mainly comprised of a terminal management main frame and numerous monitoring terminal, is responsible for a certain region.Terminal management main frame is responsible for the data interaction of field sensor network and extraneous network, and is responsible for the management of whole field sensor network, by the data of field each monitoring terminal of network collection, and sends to worm monitoring data center by cell phone network.Monitoring terminal has been realized the function of catching the automatic statistics of insect by adding photoelectric sensor on the basis of trapper, and utilizes many pointed low consumption circuit design proposals to guarantee long-time normal work of monitoring terminal in powered battery situations.
As shown in Figure 3, described monitoring terminal is insect sex attractant trap, described trapper comprises cylindrical shell 1, funnel structure 2, sensor 3, control module 4, wireless communication module 5, battery case 6, described shell upper is circumferentially evenly arranged insect and enters hole 7, described funnel structure 2 is arranged on enclosure and enters 7 belows, hole in insect, funnel structure 2 comprises the filler tube 22 of infundibular body 21 and infundibular body below, on filler tube 22, be provided with sensor 3, wireless communication module 5 and battery case 6 are in funnel structure 2 belows together, described sensor 3 is connected with control module 4, the insect that induction enters trapper, realize Auto-counting,
The filler tube of described funnel structure 2 adopts dark plastic production, reduces the impact of surround lighting on sensor, and on filler tube, sensor installation 3, described sensor is photoelectric sensor, the discharging chain of sensor is received in control module 4, and the insect that induction enters trapper, realizes Auto-counting.Control module 4(MSP430G series monolithic) with wireless communication module (5C1101 chip) be positioned over sensor 3 after, on limit, be battery case 6 together with power management module, be system power supply, fully excavate battery capacity, improve the system works life-span.
Automatically monitoring terminal schematic diagram as shown in Figure 4, monitoring terminal is comprised of sensor assembly, wireless communication module, controller module and power management module automatically.The annexation of each several part is: centered by control chip MSP430G2452, be connected respectively with sensor, wireless communication chips CC1101, battery is that various piece is powered by buck chip TPS63030.The simulating signal of sensor output becomes low and high level through the comparer of control chip inside, can cause that sensor exporting change triggers control chip and interrupts, Auto-counting during control chip handling interrupt when insect drops.Control chip is connected with wireless communication module by spi bus, and generally wireless communication chips, all in sleep state, is only just waken up when needs are communicated by letter.
Described photoelectric sensor is low power dissipation design, this sensor on the basis of traditional photoelectricity door,, select infrared tube and improved on driving circuit, as shown in Figure 6.On power valve, be connected in series the current-limiting resistance of 1k Ω, reduce power valve electric current; The emitter of receiving tube is directly connected in the base stage of a triode simultaneously, photocurrent is amplified, improve the sensitivity of receiving end;
On this basis, on radiating circuit, increase switching tube, power valve is carried out to pulsed modulation, only Monitoring Insect Pest when the high level of pulse signal.It is that 10% pulse is debugged that the present invention uses dutycycle, and the average working current of power valve reduces to original 1/20th to 1/5th.The about 0.05mA of final sensor actual measurement average current, compared with tens milliamperes of power-dissipation-reduceds of conventional photoelectric sensor 2 orders of magnitude.
The workflow diagram of the low-power consumption supervisory routine driving based on the time as shown in Figure 5, system has two kinds of duties: dormant state and event response state,
When in dormant state, the controller of monitoring terminal works in low-power consumption mode, closes all irrelevant peripheral hardwares, only retains timer and produces debug signal, and wireless communication module work is in wireless awakening state;
When in event response state, three kinds of events of monitoring terminal response, and the action that responds: 1) insect falls into trapper, trigger sensor sends the controller that electric signal wakes monitoring terminal up, counter in the controller of monitoring terminal adds one, after execution, system enters park mode again; 2) monitoring terminal receives the order of management host, wakes the controller of monitoring terminal up, completes response function, and after execution, system enters park mode again; 3) monitoring terminal receives the order of other monitoring terminals, according to certain routing rule, forwards, and after execution, system enters park mode again.
Sensor assembly schematic diagram as shown in Figure 6.The nearer feature of operating distance of the present invention's photoelectric tube during according to practical application, the current-limiting resistance (1K Ω) that increasing is serially connected on power valve reduces power valve power consumption, and by the negative pole connection control signal input port of power valve, only when control port signal is low level, generation current power valve is luminous; By receiving tube reversal connection, emitter is connected on the resistance of 40K Ω left and right, if receiving tube receives signal, produces photocurrent, will on resistance, produce so one to level output.On this basis, the input port of sensor is received in succession on the single-chip microcomputer pin with certain fan-out capability, just can be controlled easily the switch of sensor assembly.
Working sensor sequential chart as shown in Figure 7, control signal is the PWM ripple that dutycycle is higher, corresponding sensor output signal is periodic pulse signal.Sensor is when work, and in the absence that object falls into, sensor is exported regular cyclic pulse signal always; If be carved with object when some, drop and block light source, so corresponding sensor output signal will disappear until object leaves.When the low level of control signal, the low and high level of monitoring output signal just can judge whether object shading.When the cycle of control signal, be less than object and drop and block the time of sensor, just can realize the virtual real-time working of sensor.If using dutycycle is only that 10% pulse is debugged, the average working current of power valve is original 1/10th by reducing to so, can effectively reduce power valve working current.
In the time of practical application one more importantly problem be the integrity problem of sensor.The serious problem that false triggering problem when sensor is not exported and there is no worm when worm falls can be brought actual application, the design guarantees the reliability of sensor by the following method.Because the data that insect falls are slower, the dozens of millisecond that conventionally can shut out the light, makes to modulate wave period much smaller than this time just can accomplish equivalent Real-Time Monitoring.For fear of sensor output signal, at the burr that changes existence on edge, cause false triggering, controller simultaneously by rising edge and a Time delay of decline time delay definition, only responds a triggering edge in detecting sensor signal this delay time interval; The time interval for fear of the insects of different sizes when falling is different, and controller is for the variation edge of a trigger pip detection signal, when only causing once when arriving, triggers a signal intensity, and irrelevant with the length of signal duration.These measures all can guarantee the reliability of sensor.
By above design, selected infrared tube and improved on driving circuit, and infrared transmitting tube is carried out to pulsed modulation, solved the high power consumption shortcoming of traditional photoelectricity door, finally make average current drop to the more traditional photoelectricity door of 0.05mA(and reduce by 2 orders of magnitude) left and right; Sensor signal has been carried out to technical finesse simultaneously, guaranteed the reliability of sensor.
Terminal management main frame schematic diagram as shown in Figure 8, by control module, sensor network interface, GPRS communication module, solar module, formed, the main routing management of being responsible for sensor networking, the interim storage of present networks data and Monitoring Data center such as communicate at the function.Sensor network interface (CC1101), the module that provides terminal management main frame to communicate by letter with each monitoring terminal, has the hardware standard identical with whole sensor network.Control module (MSP430 single-chip microcomputer): control center, by all relevant peripheral hardwares of interface management; Sensor network administrative center, constantly updates all terminal operating status, notifies problem terminal at once; The gateway of tree network, the routing table of storing whole network, can find optimal path according to certain algorithm; The interim storage of data and simple analysis.RTC real-time clock module: timing information is provided, and according to data acquisition time is set, terminal management main frame sends instruction according to arranging from trend monitoring terminal, wakes terminal up, carries out data acquisition.Solar module: the energy is effectively provided for a long time, can supports larger power consumption.GPRS communication module: GPRS communication module is utilized cell phone network, realizes data and sends at a distance and instruction reception.Make to monitor the restriction that place is not subject to distance, facilitate the monitoring network of different stage and scale to set up.
Be illustrated in figure 9 Monitoring Data center schematic diagram, described worm monitoring data center comprises PC server and moves the database program on it.All terminal management main frames all can send the data of present networks to this domain name, server is responsible for receiving all data, then are gathered and analyzed by the data that the database program on server is responsible for each field sensor network.Yi Ge data center can manage a plurality of fields sensor network, can set up flexibly the worm monitoring network of different scales.
The present invention moves a self-defining wireless network protocol between terminal management main frame and monitoring terminal.This agreement is less for this sensor network scale, and monitoring terminal is powered battery, and communication data rate is less, and the less directly feature design such as intercommunication mutually, can guarantee the maintenance of internetwork data communication and whole network.
As shown in figure 10, present networks agreement is mainly divided into hardware layer, two parts of network layer.
Hardware layer has defined required channel parameter, address, the data packet format of Internet Transmission, and address filtering and CRC check.Whole network is operated in the ISM wave band of 433MHz, adopts GFSK modulation system to communicate, wireless communication data rate 100Kb/s.In order further to reduce power consumption, wireless communication module all in park mode, and is only waken up with wireless signal by host node in most of time at ordinary times when needs are used.
Data packet format is as shown in table 1.Data in present networks agreement and order are mainly propagated in network by the form of packet.In order to adapt to the difference in length of data and order, improve the communication efficiency of network, what in this agreement, adopt is elongated packet.
Table 1 network layer data packet format
Packet is comprised of three parts such as head, service load and afterbodys.Packet head comprises targeting signal (the 0101 random alternate sequence sending before synchronizing signal) and synchronizing signal (before sending service load, the prior appointment sync byte of 4 bytes of transmission).By the detection to targeting signal and sync byte, equipment can effectively be realized position and the byte of sync of packet.First byte of service load is the length of notebook data bag, by 8Bit, formed, support the elongated packet of from 2 to 255 bytes of length, when receiving packet, can monitor the length of packet, if the length violation of packet closes requirement, directly abandon packet.Second byte of service load is destination address, and present networks agreement is supported 16-bit address, and first eight bits is used for representing that network number is corresponding with certain rule with channel, is convenient to further expand network capacity; Rear eight each nodes for marked network.Destination address, is used to indicate the node number that packet will arrive, and supports address filtering function, and network layer is directly abandoned when receiving the packet of non-node.When destination address is 0x00, packet is broadcasted, and allly in network receives that the node of packet all processes; When destination address is other, point to point link is opened address filtering.Afterbody comprises CRC check word, and each packet can carry out 16 CRC and calculate when sending, the value of calculating gained as the afterbody of packet directly add to service load after.When packet receives, can carry out a CRC error correction, if not by CRC check, this whole packet directly abandons.
As shown in figure 11, this agreement provides a kind of network construction form based on jumping figure tree network topology, mainly comprises reset rear networking, shortest path vector route and balancing energy.
Networking after resetting: this sensor network topology of networks when application can't have greatly changed, once network is set up in the process of using in other words, unless have node to break down in network, otherwise the routing relation of network can't change.In this case, present networks agreement does not need to carry out the renewal of dynamic routing, can save a large amount of network overheads thus, but adopt a kind of similar mode that is similar to replacement, to application layer, provide a replacement interface, the search network node set up routing table of resetting again when needs upgrade routing table.
Bee-line vector route: present networks when practical application the distance between terminal and terminal generally fixing and be positioned at effective communication range within.As long as can communicate by letter between terminal and terminal, so generally link-quality can't have much difference, and can think that each link is symmetrical.For convenient judgement, this agreement chosen distance vector carries out Route Selection as criterion.
The networking process of this agreement starts hop-by-hop from management host and outwards searches for until a node farthest specifically can be divided into following a few step:
(1) management host transmitting networking demand signalling, slave receives and returns this nodal information after signaling and register to main frame; Main frame continues signaling of transmitting to confirm there is no unregistered terminal within the scope of article one, as does not have response signal to carry out (2), otherwise in a networking signaling of transmitting.
(2), on the basis of a up-to-date jumping terminal of having registered, there is each terminal of host computer control terminal that outwards search outer is jumped, and carry out Route Selection according to balancing energy principle.
(3) if do not search more outer field terminal, stop networking, otherwise repeating step (2).
Balancing energy: low-power consumption network need to guarantee that whole network can effectively work long hours, this just requires each terminal in network can both balancedly be assigned with as much as possible network task.Once the foundation of assurance route also should be considered this problem, avoids as far as possible setting up too much route by same terminal, or this can be become to balancing energy.
