Description
Technical field
The present invention relates to the communication means of a kind of plant maintenance and configuration, system and communication means thereof are put in especially a kind of plant maintenance and configuration based on the Zigbee technology, belong to wireless communication technology field.
Background technology
ZigBee is the double-direction radio communication network technique of a kind of emerging short distance, low-power consumption, low data rate, low cost, low complex degree, take the physical layer and the MAC layer of IEEE 802.15.4 agreement, and increased network layer, network security and application layer on this basis.
The Zigbee network is made up of three kinds of network nodes: network coordinator, routing node, terminal node.Network coordinator comprises all internet messages, and memory capacity is big, computing capability is the strongest, sends networked beacons, sets up a network, managing network node, storage networking nodal information, seeks a pair of internodal route messages, receives message incessantly; Routing node is the relaying in the network, connects each node of network, the coverage and the network size of extension and extended network.Terminal node is can only directly send out message to give network coordinator and routing node, and the data message of all collections all passes through this node and enters the Zigbee communication network, and is low to the demand of disposal ability and internal memory.
Equipment can be through debugging and detection before dispatching from the factory, debugging before dispatching from the factory all is to be undertaken by network interface, serial ports or light mouth with detecting basically, be external netting twine, Serial Port Line or optical fiber main frame, come equipment is debugged and disposed by main frame to debugging, detection and configuration.Yet after equipment dispatches from the factory to the user, equipment probably operates under the comparison rigorous environment, in case after installing, manpower is difficult to touch, upgrading, configuration and debugging to field apparatus will be very difficult, need manually touch equipment, connect netting twine, Serial Port Line or optical fiber and pull out, just can debug, safeguard and dispose.But danger often occurs in and manually touches equipment, connects in the process that netting twine, Serial Port Line or optical fiber pulls out, and is simultaneously also poor on user experience.
Such as being used for the outdoor switch terminal unit device of urban and rural power grids in the electric power system, this device is responsible for the switching value of switchgears such as on-pole switch and the collection of measuring amount, the Fault Identification of feeder line, fault location, Fault Isolation.This device is installed on the shaft tower, and the user need climb up shaft tower to the maintenance and the configuration of this equipment, connect very long netting twine, and then get back on the ground, network interface being inserted computer carry out on-site maintenance and configuration, it is exactly the process of comparison danger that the process of line is drawn in the net in pole-climbing.
Summary of the invention
The objective of the invention is to address the above problem, it is the following time of condition that device context operates in more complicated, adopt wired mode that equipment is debugged, safeguarded and disposes, need manually line to be connected equipment and computer, and artificial this process of line is likely comparison danger, and reduces user experience.
The technical solution used in the present invention is:
A kind of plant maintenance and configuration-system based on the Zigbee technology, comprise terminal node and network coordinator in the Zigbee network, it is characterized in that: terminal node is connected with equipment, network coordinator is connected with computer or hand-held maintenance terminal, is come the debugging, maintenance and the configuration data that transmit between load bearing equipment and the computer by network coordinator and the formed network of terminal node.
Aforesaid plant maintenance and configuration-system based on the Zigbee technology, it is characterized in that: terminal node comprises dual mode with being connected of maintained equipment room, a kind of mode is directly made terminal node a circuit board, power by equipment, link by pin then, adopt the serial asynchronous communication mode between equipment and the terminal node; Another kind of mode is packaged into micro device with terminal node, and micro device and equipment room adopt wired connection, and interface can adopt various ways such as RS232, RS485 or network interface.
Adopt USB interface between network coordinator and the computer, after itself and computer connect, automatically USB interface is mapped to COM serial port, follow general RS232 interface protocol with communicating by letter between the device management application on the computer; Network coordinator is powered by USB interface of computer.
A kind ofly it is characterized in that, may further comprise the steps based on the plant maintenance of Zigbee technology and the communication means of configuration-system:
1) realize the Zigbee protocol stack at terminal node, directly link to each other by pin between terminal node and the maintained equipment or Serial Port Line continuous, realization UART communicates by letter on this pin or Serial Port Line;
2) realize the Zigbee protocol stack at network coordinator, between network coordinator and computer, adopt USB interface to link to each other;
3) at first set up the Zigbee network of a certain channel by network coordinator, after terminal node is searched this network, carry out network and add application;
4) terminal node is carried out safety certification, authentication is passed through, and 2 radio channels are set up;
5) maintained equipment transmits and receive data from the UART interface, the management application program receives and sends data from USB interface, and tune-up data, configuration data and edition data between maintained equipment and the management application program all will transmit by the radio channel of this Zigbee.
The conspicuousness progress and the characteristics of technical solution of the present invention are mainly reflected in: make full use of characteristics such as the low-power consumption of Zigbee technology, low complex degree and short distance, be applied in the maintenance and configuration of field apparatus; No longer adopt wired mode to carry debugging, configuration and software version data, and adopt wireless mode to carry, increase the convenience of safeguarding greatly, strengthened user experience, user even can directly carry out the work of plant maintenance in car need not to safeguard and configuration effort under abominable equipment operating environment.
