Abstract
A low-cost multifunctional Eoc system comprises an upper computer and an Eoc coordinator; a sensor terminal node and a coordinator node form a network; the sensor terminal node is used for collecting sensor data and transmitting the sensor data to the coordinator node through an Eoc protocol; the coordinator node is used for establishing and maintaining a wireless network and collecting the information of terminal nodes to transmit the information to the upper computer software through a serial port; the upper computer is used for sending an instruction to the Eoc coordinator in a TCP/IP (Transmission Control Protocol/Internet Protocol) transparent transmission mode; the Eoc coordinator is used for transmitting a data package to the specified terminal node through a Zstack protocol; an execution result data package is returned to a TCP connection server of the upper computer through the Eoc coordinator after the terminal node receives the data package and the related action is performed.
Description
Technical field
The present invention relates to the multi-functional Eoc system of a kind of low cost, belong to Eoc field.
Background technology
WiFi is the Radio Transmission Technology based on IEEE802.11 standard, is the radio signal supporting linking Internet.Be characterized in that wireless data transmission rate is high, meet the demand of individual and social informatization, be widely used at present in the terminal such as PC, handheld device (as PDA, mobile phone).
Eoc is the Radio Transmission Technology based on IEEE802.15.4 standard, be a kind of closely, low complex degree, self-organizing, low-power consumption, low data rate, low cost wireless networking standard.Be widely used in the applications such as Smart Home, building automatic, Industry Control at present.
Although WiFi possesses the ability of high-speed data communication, family, the indispensable network components of office personal information network are become, but because WiFi cost is higher and power consumption is larger, therefore in these fields still large number quipments due to the restriction of supply power mode and cost, WiFi technology cannot be used to come and other equipment networkings, could must realize and other equipment wireless interconnected by Eoc technology.Along with the development of Internet of Things application, radio sensing network will extend to each corner, and single wireless network cannot cover all application demands, and the hybrid network be made up of these two kinds of difference technology of leading to of WiFi and Eoc will become more and more popular and become main flow.Therefore, the demand realizing data message seamless delivery between WiFi network and Eoc network is more and more urgent, become a huge bottleneck of technology of Internet of things development, data flow is generally flow to host computer from the coordinated device of terminal node, and reverse data communication is difficult to realize.
Summary of the invention
The invention provides the multi-functional Eoc system of a kind of low cost, solve host computer as when sent the terminal node of reverse communication instruction to Eoc network, and obtain feedback result information for this reason, the present invention adopts following technical scheme:
The multi-functional Eoc system of a kind of low cost, comprise host computer, Eoc telegon, sensor terminal node and a coordinator node form a network, wherein sensor terminal node is responsible for pick-up transducers data and is sent coordinator node to by Eoc agreement, coordinator node is responsible for setting up wireless network and maintenance, the information of its collection terminal node sends upper computer software to by serial ports, host computer is by TCP/IP transparent transmission mode, instruction is sent to Eoc telegon, telegon by Zstack agreement by data packets to the terminal node of specifying, terminal node is returned execution result packet after receiving the laggard line correlation action of packet and is got back on the TCP connection server of host computer by Eoc telegon.Coordinator node hardware designs: telegon is by CC2530 wireless module, power supply, MAX232 serial port chip, jtag interface circuit and part peripheral circuit composition, what coordinator node was responsible for Eoc network builds on maintenance, also to pass through serial communication with PC, realize on PC by host computer monitoring intelligent house system, MAX232 serial port chip is used for realizing coordinator node and communicates with PC com port, because the operating voltage of CC2530 is at 2.0V-3.6V, so we need AMS1117 voltage stabilizing conversion chip to be transferred by external power source provide the supply voltage of stable 3.3V to telegon, ensure the normal work of chip.
Accompanying drawing explanation
Fig. 1 is that present system realizes principle schematic.
Embodiment
Below in conjunction with accompanying drawing, by the citing of indefiniteness, the preferred embodiment of the present invention is described further, a kind of Eoc reverse communication and control method, comprise host computer, Eoc telegon, sensor terminal node and a coordinator node form a network, wherein sensor terminal node is responsible for pick-up transducers data and is sent coordinator node to by Eoc agreement, coordinator node is responsible for setting up wireless network and maintenance, the information of its collection terminal node sends upper computer software to by serial ports, host computer is by TCP/IP transparent transmission mode, instruction is sent to Eoc telegon, telegon by Zstack agreement by data packets to the terminal node of specifying, terminal node is returned execution result packet after receiving the laggard line correlation action of packet and is got back on the TCP connection server of host computer by Eoc telegon.
Coordinator node hardware designs: telegon is by CC2530 wireless module, power supply, MAX232 serial port chip, jtag interface circuit and part peripheral circuit composition, what coordinator node was responsible for Eoc network builds on maintenance, also to pass through serial communication with PC, realize on PC by host computer monitoring intelligent house system, MAX232 serial port chip is used for realizing coordinator node and communicates with PC com port, because the operating voltage of CC2530 is at 2.0V-3.6V, so we need AMS1117 voltage stabilizing conversion chip to be transferred by external power source provide the supply voltage of stable 3.3V to telegon, ensure the normal work of chip.
