Embodiment
As shown in Figure 1, the a kind of of the present embodiment comprises a monitoring server 1 based on the wireless interconnected environmental monitoring system of ZigBee, described monitoring server 1 connects a gateway 2 by wireless network, described gateway 2 and a plurality of telegon 3 wireless connections row data communication of going forward side by side, each telegon 3 connects a plurality of sensors bunches 4 of a plurality of monitoring humitures by ZigBee mode.
In the present embodiment, in each described sensor bunches 4, comprise respectively a plurality of random sensor nodes 41 that closely distribute and with the sensor cluster head 42 of each sensor node 41 with the wireless connections of ZigBee mode communication, described sensor cluster head 42 connects telegon 3 by ZigBee mode.Fig. 1 hollow core circle represents that sensor node, solid circles represent that sensor cluster head, hollow triangle represent telegon.
As shown in Figure 2, in the present embodiment, described sensor node 41 comprises data acquisition module 411, data processing module 412 and the data communication module 413 connecting successively, and described data acquisition module 411, data processing module 412 and data communication module 413 are connected with a power module 414.The concrete module composition of sensor cluster head 42, telegon 3 is similar to sensor node 41, not in repeat specification, difference is, module in sensor node is low energy-consumption electronic device, and the most of the time, node was in park mode, therefore power module adopts 2 joint AA batteries, conventionally can not supply node work 6 months to 2 years not etc.; And sensor cluster head 42 and the frequent forwarding data of telegon 3 need to expend a large amount of energy,
Can adopt if desired the power supplys such as photoelectric cell to power.
As shown in Figure 3, in the present embodiment, described data acquisition module 411 comprises sensor unit 4111 and A/D converting unit 4112, and described data processing module 412 comprises a processor 4121 and storer 4122; Described data communication module 413 comprises network element 4131, MAC unit 4132 and Transmit-Receive Unit 4133.
Because the present embodiment is when monitoring, need to gather humiture information and smog information, so in the present embodiment, described sensor unit 4111 comprises Temperature Humidity Sensor and smoke transducer.Wherein smoke transducer fundamental purpose is when carrying out air monitoring, and forest fire is carried out to early warning.
As shown in Figure 4, in the present embodiment, described gateway module 2 comprises that a control module 21, described control module 21 are connected with NAND storage unit 22, sdram memory 23, radio frequency unit 24, GPRS unit 25, I/O interface 26 and power supply unit 27.
In this enforcement, described monitoring server comprises communication server and data server.The communication server and gateway carry out exchanges data by GPRS network, and data server is preserved the environmental data receiving, and the services such as management, inquiry and editor of data are provided.
Aspect parts selection, the sensor node of the present embodiment selects the CC2430 of TI company production as core devices, CC2430 is integrated meets the radio-frequency (RF) transceiver of IEEE802.15.4 standard, work in 2.4GHz frequency range, 8051 microcontrollers of built-in high-performance, low-power consumption, and the A/D converter of 14.The sensitivity of CC2430 is-91dBm that maximum output is+0.6dBm that maximum transfer rate is 250Kbps, and has good interference free performance.CC2430 adopts low-voltage (2.0-3.6V) power supply, current drain 0.9 & mu only during dormant state; A, from park mode, being switched to aggressive mode only needs 15ms.These characteristics make CC2430 be suitable for finite energy but require the environmental monitoring of long-term continuous working.
The SHT11 sensor that Temperature Humidity Sensor adopts Sensirion company to produce, it adopts the digital output interface of 12C bus, the accurate relative temperature of whole school and humidity output are provided, there is dew point value and calculate output function, can directly be connected with microcontroller, have that the debugging of exempting from, non-calibrating, precision are high, auto sleep and a medium feature of immersion water completely.Its volume is small and exquisite, low in energy consumption, and working current is 550 μ A only.
Smoke transducer adopts semi-conductor gas smoke transducer MS5100, and short, good stability of its response time has higher sensitivity to smog, hydrocarbon and oxide etc. in wider concentration range.
The data traffic of gateway, far away higher than sensor node, needs stronger data processing and control ability, the AT91SAM9261 microprocessor of therefore selecting Atmel company to produce.This processor, based on ARM926EJ-S kernel, is 32 RISC flush bonding processors of a high-performance, low-power consumption, and when clock frequency is 190MHz, processing power is up to 210MIPS; When peripheral hardware all starts, working current only has 65mA.Radio-frequency (RF) receiving and transmission module is CC2430, is responsible for carrying out two-way communication with the wireless telegon of ZigBee; The G20 that GPRS wireless communication module selects motorola inc to produce, connects by GPRS network and Surveillance center, realizes the remote radio communication of data.
During work, in order to reduce energy consumption, the working method that system adopts dormancy one to wake up.Node in ZigBee wireless sensor network is not always in running order, and only, when receiving the data query order that Surveillance center sends, node is waken up and proceeds to duty, completes the work such as the collection of data and forwarding; Otherwise node will be in dormant state.
After system starts, the initial work such as setting parameter of finishing equipment first.ZigBee telegon is responsible for setting up network, and waits for that other node adds network, enters dormant state with posterior nodal point.Surveillance center is by GPRS network after ZigBee gateway sends the order of data query, and telegon carries out communication broadcast to bunch network that is under the jurisdiction of it, wakes the cluster head that needs data query up, and dormancy node is broadcasted and waken up to cluster head to other node of this bunch again; After node image data, re-send to cluster head, cluster head is carried out the synthetic Hou Yanyuan road of processing of data and is fed back to gateway; Finally, gateway transfers data to Surveillance center by GPRS network again.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
