Abstract
The invention provides grain condition monitoring system based on a wireless Ad Hoc network, which is high in efficiency and convenient for installation and maintenance. According to the system, grain condition data sensors are connected together in granaries through a one-line bus, and outside of the granaries, all granaries in a whole grain storage station are interconnected through a wireless sensor network with the Ad Hoc network and self-healing property. A gateway node in the wireless Ad Hoc network is provided with a GPRS (General Packet Radio Service) network interface or an LAN (local area network) interface which can be accessed to a VPN (Virtual Private Network) so as to collect grain condition data of a plurality of grain storage stations to a grain condition public data platform in a grain system.
Description
Technical field
The inventive method relates to the wireless self-networking network, relates in particular to a kind of grain condition monitoring system based on wireless self-networking.
Background technology
Grain is in process of storing, and the variation of environment (temperature, humidity, moisture etc.) directly has influence on the quality of grain quality, because storage is improper, can cause a large amount of foodstuff wastes.Therefore grain feelings supervisory system stores the very important effect of playing at grain.
Grain feelings supervisory system is two kinds mostly at present, and a kind of is to use the thermometric bar, and this mode almost is complete manual queries, has no advantage; Another kind is to adopt wired mode, and each silo is connected to Surveillance center, and this mode has following several defective: the RS485 bus is higher to the quality requirements of communication cable, makes cost improve greatly; In case cable is connected lightning strike accident taking place, causes the damage of large tracts of land even whole grain information monitoring system easily; The communication cable easy ageing needs the cost of replacing and maintenance all higher.
This grain information monitoring system is the hardware and software platform that high-tech means such as, computer technology technological through wireless self-networking technology, GPRS and measuring technique combine; Realize informationization and intelligent management that grain stores, can solve above-mentioned two kinds of problems that system ran into.
Summary of the invention
The technical matters that the present invention will solve is: design a kind of efficient height and installation and maintenance grain condition monitoring system extremely easily.
In order to solve the problems of the technologies described above, the invention provides a kind of grain condition monitoring system based on wireless self-networking.This system is made up of wireless self-networking grain feelings collector, wireless self-networking gateway node, grain feelings common data platform.According to grain condition monitoring system standard, dispose parameter sensors such as temperature, humidity, moisture in silo inside, the mode through one-line bus with the data acquisition of all the sensors to wireless self-networking grain feelings collector.Each silo is installed a wireless self-networking grain feelings collector; After powering on, wireless self-networking grain feelings collector on all silos at whole grain storage station seeks the wireless self-networking gateway node automatically; The wireless self-networking gateway node couples together all collectors; Form a wireless network, this network has self-organization and self-healing property.The wireless self-networking gateway node is not only the center aggregation node of wireless self-networking; And be the bridge of wireless self-networking and other network information transfer; After it collects the grain feelings data of each silo; Can insert Internet through GPRS network or lan network, with the grain feelings common data platform of data transfer to the Internet.
Technical scheme of the present invention is compared prior art has following advantage:
1. it is convenient to install, and not doing under the situation of bigger adjustment existing storehouse and facility, just can each wireless self-networking grain feelings collector be in place through wireless mode.
2. easy to maintenance, the self organizing function of wireless sensor network: need not manual intervention, structurized network is formed in the existence that network node can other nodes of perception, and definite annexation;
3. the self-healing function of wireless sensor network increases and perhaps deletes a node, node location change; Node breaks down or the like, and network can both self-regeneration, and network topology structure is correspondingly adjusted; Need not manual intervention, guarantee that total system still can operate as normal.
4. reliable communications, wireless self-networking has adopted the collision-avoidance mechanism of CSMA-CA, simultaneously for to need the communication service of fixed-bandwidth to reserve dedicated time slot, competition and conflict when having avoided sending data; The MAC layer has adopted the data transmission mechanism of full confirmation, and the packet of each transmission all must be waited for take over party's affirmation information.

Embodiment
As shown in Figure 1, the grain condition monitoring system of the present invention's design comprises grain condition monitoring system and grain feelings common data platform two parts:
The grain condition monitoring system by: wireless self-networking grain feelings acquisition node and wireless self-networking gateway node are formed.Wireless self-networking grain feelings acquisition node has comprised wireless self-networking unit, one-line bus control drive unit, main control unit and supply control unit.According to grain condition monitoring system standard, dispose parameter sensors such as temperature, humidity, moisture in silo inside, the mode through one-line bus with the data acquisition of all the sensors to wireless self-networking grain feelings collector.Each silo is installed a wireless self-networking grain feelings collector; After powering on, wireless self-networking grain feelings collector on all silos at whole grain storage station seeks the wireless self-networking gateway node automatically; The wireless self-networking gateway node couples together all collectors; Form a wireless network, this network has self-organization and self-healing property.The wireless self-networking gateway node is not only the center aggregation node of wireless self-networking; And be the bridge of wireless self-networking and other network information transfer; After it collects the grain feelings data of each silo; Can insert Internet through GPRS network or lan network, with the grain feelings common data platform of data transfer to the Internet.
2. grain feelings common data platform is made up of fire wall, data transmission and processing server, relational database and Web server.This platform can let the whole province and even national grain storage station insert through Internet, receives grain feelings data, and grain feelings data, services can be provided on Internet.
As shown in Figure 2, the inner cable for measuring temperature deployment architecture of a silo figure, this silo is divided into two Ao Cang, and each Ao Cang is 3 groups of cable for measuring temperature respectively, every group totally 10.It is inner that these 60 cable for measuring temperature are inserted grain, with monitoring grain internal temperature situation.The outside pe sheath that adopts of cable for measuring temperature has dismountable connector with bus, and there are two tension steel wires inside, and tensile strength can reach 250 kilograms.3 DS18B20 digital temperature sensors of parallel connection above the every cable.After grain is stacked well,, cable for measuring temperature is inserted into the bottom of grain heap with elongated iron fork guiding.Getting up through socket and one-line bus parallel connection in the top of cable, and inserts wireless sensor node.Sensor node just can read tens temperature values above the cable through one-line bus like this.The sheath of cable is to be processed by special material, has erosion-resisting characteristics, does not receive the influence of grain depot recirculation fumigation.
The present invention is based on wireless self-networking, make convenient for installation and maintenance, efficient is high and safe reliability is high, can be widely used in the middle of the various silos.
