Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
In consideration of the environment monitoring mode based on the ZigBee in the prior art, because the environment monitoring mode is limited by the effective communication range of the ZigBee local area network, data collected by nodes which are relatively distributed and dispersed in space or nodes which are relatively far away cannot be well monitored, and therefore the applicability is poor. Based on the above, the embodiment of the invention provides a remote environment monitoring system, which is based on the ZigBee technology and the GPRS technology to realize the real-time monitoring of local and remote environments, and has better applicability.
An embodiment of the present invention provides a remote environment monitoring system, which specifically includes, referring to fig. 1: the ZigBee monitoring system comprises a main sensing network constructed through ZigBee, at least one auxiliary sensing network constructed through ZigBee, a communication module 11 and a monitoring terminal 22, wherein the communication module 11 is used for realizing data transmission of the main sensing network and the auxiliary sensing network; wherein,
the main sensing network is used for acquiring first environmental parameter data of a current first monitoring area acquired by a sensor accessed by the main sensing network in real time and uploading the first environmental parameter data to the monitoring terminal 22 through a standard communication interface; inversely converting the standard second environment parameter data sent by the communication module 11 into second environment parameter data, and uploading the second environment parameter data to the monitoring terminal 22 through the standard communication interface;
the slave sensor network is used for acquiring second environment parameter data of a current second monitoring area acquired by a sensor accessed by the slave sensor network in real time, and converting the second environment parameter data to obtain standard second environment parameter data;
the communication module 11 is configured to send the standard second environment parameter data to the main sensor network;
and the monitoring terminal 22 is used for displaying the first environmental parameter data and the second environmental parameter data.
Compared with the prior art in which the environment monitoring method based on the ZigBee is limited by the effective communication range of the ZigBee local area network and the remote monitoring effect is not good, the remote environment monitoring system provided in the embodiment of the invention has poor applicability, in which the first environment parameter data of the current first monitoring area and the second environment parameter data of the second monitoring area are respectively obtained through the main sensing network and the slave sensing network, for the main sensing network, the obtained first environment parameter data are directly uploaded to the monitoring terminal 22 for display, for the slave sensing network, the obtained second environment parameter data are firstly converted, and then the converted standard second environment parameter data are sent to the main sensing network through the communication module 11, so that the reversely converted second environment parameter data are uploaded to the monitoring terminal 22 for display through the main sensing network, the method not only realizes local monitoring of the environment where the main sensing network is located, but also realizes remote monitoring of the environment where the auxiliary sensing network is located, and has better applicability.
Specifically, in consideration of a specific application environment of the remote environment monitoring system provided by the embodiment of the present invention, the master sensor network and the slave sensor network in the embodiment of the present invention are both wireless sensor networks constructed by using the ZigBee technology, wherein the master sensor network acquires, in real time, first environment parameter data of a current first monitoring area acquired by a sensor connected thereto; and acquiring second environment parameter data of the current second monitoring area acquired by the sensor accessed to the sensor network in real time from the sensor network.
The main sensing network and the slave sensing network are used as ZigBee networks, and three ZigBee devices are adopted, namely a coordinator, a router and a terminal node. Referring to fig. 1, a specific structural diagram of a master sensor network and a slave sensor network is adopted in the remote environment monitoring system provided by the embodiment of the present invention, wherein a coordinator is used as a core of the network and is responsible for establishing, maintaining and managing the network, allocating network addresses, and the like. The router is used as data routing equipment in the network and is mainly responsible for finding the optimal data transmission route in the network, reducing the data forwarding times, reducing the overall power consumption of the network and prolonging the service life of the network. The terminal node is used as the end of the network, can only receive and transmit data, and has no functions of data routing and forwarding.
For the main sensor network, the remote environment monitoring system provided in the embodiment of the present invention directly uploads the acquired first environment parameter data to the monitoring terminal 22 through the standard communication interface; for the slave sensor network, the system needs to send the acquired second environment parameter data to the master sensor network through the communication module 11, so as to upload the second environment parameter data to the monitoring terminal 22 indirectly through the master sensor network through the standard communication interface.
Considering that GPRS (General packet radio Service) is used as a set of mobile phone mode communication services based on Global System for mobile communication (GSM), and its basic function is to transmit packet data between a mobile terminal and a router of an Internet network, and the communication module 11 in the embodiment of the present invention preferably uses a GPRS module. Namely, the remote environment monitoring system provided by the embodiment of the invention is a ZigBee-GPRS hybrid system, and can realize remote interconnection between a master sensing network and a slave sensing network.
In addition, in order to facilitate data transmission through the GPRS module, the slave sensor network in the embodiment of the present invention further performs conversion processing on the obtained second environment parameter data to obtain standard second environment parameter data, where the ZigBee network corresponding to the slave sensor network realizes conversion processing of the data through the ZigBee radio frequency signal antenna, the ZigBee wireless transceiver chip, and the corresponding processor. Correspondingly, the main sensing network also carries out inverse conversion processing on the standard second environment parameter data sent by the GPRS module to obtain the second environment parameter data, wherein the ZigBee network corresponding to the main sensing network carries out inverse conversion processing through the ZigBee radio frequency signal antenna, the ZigBee wireless receiving and sending chip and the corresponding processor, and the corresponding GPRS module is also provided with the corresponding GPRS radio frequency signal antenna.
Further, the main sensor network is used as a ZigBee network, see fig. 1, and is composed of a plurality of first terminal nodes, a plurality of first routers, and a first coordinator; wherein the first terminal node can directly establish a direct transmission link with the first coordinator; or the first terminal node accesses one or more first routers and establishes a plurality of preset transmission links through the first routers.
The hardware structures adopted by the first terminal node, the first router and the first coordinator are basically the same, and different functions are embodied after the different devices are configured through related software. The first terminal node is responsible for collecting the first environment parameter data, the first router plays a role in starting and stopping, on one hand, the first router is responsible for smoothly transmitting the data acquired by the first terminal node to the first coordinator, and on the other hand, the first router is responsible for transmitting commands issued by the first coordinator. The first terminal node comprises a sensor module, a processor CC2530 module, a power supply module, an antenna module and the like, the first router comprises all modules except the sensor module, and the first coordinator comprises a ZigBee wireless communication module, a processor module, a power supply module, a data storage module and the like. In particular, the method comprises the following steps of,
the first terminal node can be connected with corresponding sensors according to environmental requirements, for example, for gardens, a temperature sensor, a humidity sensor and an illumination sensor can be connected, for a storage chamber, a smoke sensor, a temperature sensor and an anti-theft sensor can be connected, first environmental parameter data of a current first monitoring area acquired by the sensors are acquired, then an optimal path is selected from the direct transmission link or the plurality of preset transmission links, and the acquired first environmental parameter data are sent to the first coordinator, wherein the first environmental parameter data carry a first network identifier.
Because the first terminal node does not need to forward data, the first terminal node can enter a dormant state to reduce power consumption in an idle period after data sending is finished, next acquisition and data sending to the first coordinator are not carried out until the first terminal node is awakened by a timer, and in the dormant state, the current consumption of the node is about a few microamperes, so that the first terminal node can be used for months enough for two No. 5 batteries, and therefore the first terminal node has high practicability.
In addition, when the first router forwards data, it may forward the first environmental parameter data sent by the first terminal node that is accessed to the first coordinator, and the first coordinator performs redundancy processing after recognizing the first network identifier of the first environmental parameter data to obtain valid data, and uploads the data to the monitoring terminal 22 through the standard communication interface to implement real-time monitoring.
In order to prevent the first coordinator from receiving a large amount of information at the same time at a certain time, the first router sets a time interval to a random number between 5000ms and 15000ms every time data is forwarded. In addition, the network node can be controlled to collect information at any time through key operation of the first coordinator or related operation of the monitoring terminal 22.
Further, the first router may further convert the standard second environment parameter data sent by the communication module 11 into second environment parameter data, and forward the second environment parameter data to the first coordinator, so as to upload the second environment parameter data to the monitoring terminal 22 through the standard communication interface, and similarly, the first coordinator may also convert the standard second environment parameter data sent by the communication module 11 into the second environment parameter data, and upload the second environment parameter data to the monitoring terminal 22 through the standard communication interface.
In addition, considering that the master sensor network has three networking modes, namely a star network, a tree network and a mesh network, the mesh network has strong self-organizing and self-healing functions in a communication range, can form a very complex network, has great routing depth and network node scale, and can also communicate in a multi-hop mode, so that the master sensor network in the remote environment monitoring system provided by the embodiment of the invention preferably adopts the networking mode of the mesh network.
In the networking process, the first terminal node sends the acquired first environment parameter data to the first coordinator through the minimum selection path; the minimum selection path is an optimal path selected from a direct transmission link and a plurality of preset transmission links according to the environment of the current first monitoring area;
when any first router in one of the preset transmission links is abnormal, the main sensing network automatically searches for an optimal path from the direct transmission link or other preset transmission links. That is, when a router is disconnected, the information that would pass through the router automatically bypasses the node, and searches for other effective links to continue transmitting data.
Further, considering that the slave sensor network and the master sensor network are both ZigBee networks and similarly comprise a plurality of second terminal nodes, a plurality of second routers, and a second coordinator, see fig. 1, where the second terminal nodes can directly establish a direct transmission link with the second coordinator; or the second terminal node accesses one or more second routers and establishes a plurality of preset transmission links through the second routers.
The hardware structures adopted by the second terminal node, the second router and the second coordinator are basically the same, and different functions are embodied after the different devices are configured through related software. The second terminal node is responsible for collecting the second environment parameter data, and the second router plays a role in starting and stopping, on one hand, the second router is responsible for smoothly transmitting the data acquired by the second terminal node to the second coordinator, and on the other hand, the second router is responsible for transmitting commands issued by the second coordinator. The second terminal node comprises a sensor module, a processor CC2530 module, a power supply module, an antenna module and the like, the second router comprises all modules except the sensor module, and the second coordinator comprises a ZigBee wireless communication module, a processor module, a power supply module, a data storage module and the like. In particular, the method comprises the following steps of,
the second terminal node can be connected with a corresponding sensor according to environmental requirements, for example, for gardens, a temperature sensor, a humidity sensor and an illumination sensor can be connected, for a storage chamber, a smoke sensor, a temperature sensor and an anti-theft sensor can be connected, second environmental parameter data of a current second monitoring area acquired by the sensors are acquired, an optimal path is selected from the direct transmission link or the plurality of preset transmission links, and the acquired second environmental parameter data are sent to the second coordinator, wherein the second network identification is carried in the second environmental parameter data.
The second terminal node does not need to forward data, and can enter a dormant state to reduce power consumption in an idle period after data sending is finished, next acquisition and data sending to the first coordinator are not carried out until the second terminal node is awakened by the timer, and in the dormant state, the current consumption of the node is about a few microamperes, so that the second terminal node can be used for months enough for two No. 5 batteries, and therefore the second terminal node has high practicability.
In addition, when the second router forwards data, the second router may forward second environment parameter data sent by an accessed second terminal node to the second coordinator, and the second coordinator performs redundancy processing after identifying a second network identifier of the second environment parameter data to obtain valid data, and performs conversion processing on the processed second environment parameter data, and sends the converted standard second environment parameter data to the communication module 11, so as to send related data to the main sensor network through the communication module 11 to implement data uploading.
In order to prevent the first coordinator from receiving a large amount of information at the same time at a certain time, the second router sets a time interval to a random number between 5000ms and 15000ms every time data is forwarded. In addition, the network node can be controlled to collect information at any time through key operation of the first coordinator or related operation of the monitoring terminal 22.
Further, the second router may further convert the second environment parameter data into standard second environment parameter data, and send the standard second environment parameter data to the communication module 11, so as to send the relevant data to the main sensor network through the communication module 11 to implement data uploading.
Similarly, considering that the slave sensor network has three networking modes, namely a star network, a tree network and a mesh network, the mesh network has strong self-organizing and self-healing functions in a communication range, can form a very complex network, has a large routing depth and a large network node scale, and can also communicate in a multi-hop mode, so that the slave sensor network in the remote environment monitoring system provided by the embodiment of the invention preferably adopts the networking mode of the mesh network.
In the networking process, the second terminal node sends the acquired second environment parameter data to the second coordinator through the minimum selected path; the minimum selection path is an optimal path selected from the direct transmission link and the plurality of preset transmission links according to the environment requirement of the current second monitoring area; the second terminal node directly establishes a direct transmission link with the second coordinator; or the second terminal node accesses one or more second routers and establishes a plurality of preset transmission links through the second routers;
when any second router in one preset transmission link is abnormal, the slave sensor network automatically searches for an optimal path from a direct transmission link or other preset transmission links. That is, when a router is disconnected, the information that would pass through the router automatically bypasses the node, and searches for other effective links to continue transmitting data.
In order to better adapt to the building scale of the system, the embodiment of the invention designs two working modes of the monitoring terminal 22, one mode is that the first environment parameter data and the second environment parameter data are uploaded to the monitoring terminal 22 through a serial port, the functions of storing and processing the data by using the large-capacity storage space of the monitoring terminal 22 are utilized for processing, the first coordinator can transmit the data to the monitoring terminal 22 for processing only by performing simple identification and redundant processing on the data, at the moment, the first coordinator is equivalent to a unit for exchanging the data between the monitoring terminal 22 and the outside, at the moment, corresponding management software needs to be configured on the monitoring terminal 22, and the control and management of the wireless sensor network are realized. In another scheme, a liquid crystal display is directly connected to the first coordinator, the first coordinator is used for processing data and the data is displayed through the monitoring terminal 22, and at this time, the first coordinator needs a large amount of work and is not suitable for large-scale expansion and is suitable for small-scale application.
