Description
Technical field
The utility model relates to a kind of data collector, specifically a kind of power dispatching data acquisition terminal based on ZigBee.
Background technology
ZigBee is wireless near field communication network standard of new generation, and regional subnet is set up in specific local zone of its network coverage, but have that low-power consumption, low cost encryption are strong, topology flexibly, the characteristics such as intelligent networking.The ZigBee application comprises the occasions such as data acquisition, wireless industrial control, family and building are automatic, change remote network control.To many, the wide power domain of distributor point, ZigBee communication has wide utilization prospect.
In the last few years, along with the distribution automation degree improves constantly, main website was more and more higher for the image data transmission requirement of distribution terminal.At present in the distribution terminal, its Wireless Telecom Equipment major part is to adopt integration module, but common radio communication integration module exists two large defectives: a defective is the baffled deadlock of communication module, it is bright that concrete phenomenon shows as run indicator, and serial ports causes main website can not in time understand the ruuning situation of terminal without transceiving data, more can't remote terminal equipment, the maintainer need climb up electric pole, could manually restart recovery system.For many, the wide terminal of distributor point, safeguard to get up to waste time and energy; The another one defective is: the transmitting-receiving spatial cache of data transmit-receive module is limited, can't store simultaneously a large amount of data.When the ZigBee module passes data to convergent point simultaneously, will cause the convergent point data to be stopped up, and obliterated data is serious.When backbone has a power failure, many power equipments will at Millisecond in the time, outwards send data in hundreds of meters scopes in the distribution process, and the data of uploading for Rendezvous Point ZigBee module produce " competition ", cause loss of data.
The utility model content
The deficiency that exists for overcoming above-mentioned prior art, the utility model provides a kind of power dispatching data acquisition terminal based on ZigBee, its not only low in energy consumption, memory data output is large, and can effectively prevent the generation of traditional communication module deadlock phenomenon.
The technical scheme in the invention for solving the technical problem is: based on the power dispatching data acquisition terminal of ZigBee, send to master station computer in order to the power dispatching data that gathers distribution terminal and by wireless transmission method, it is characterized in that, comprise single-chip microcomputer, the ZigBee module, serial port drive buffer circuit and power module, described single-chip microcomputer is connected with distribution terminal by the serial port drive buffer circuit, described ZigBee module is connected with single-chip microcomputer, and be connected with master station computer by the ZigBee wireless communication mode, described power module respectively with single-chip microcomputer, the ZigBee module, the serial port drive buffer circuit is connected with distribution terminal.
Preferably, described single-chip microcomputer comprises the MSP430F5843A chip.
Preferably, described distribution terminal comprises DTU terminal, FTU terminal or TTU terminal.
The beneficial effects of the utility model are, after adopting said structure, the utility model not only has the characteristics such as low in energy consumption and memory data output is large, effectively prevented the generation of traditional communication module deadlock phenomenon, and avoided " competition " that many station power distributions terminal device produces to the Rendezvous Point uploading data simultaneously under the circuit abnormal conditions, improved the reliability of data transmission.The utility model is applicable to 10KV outdoor aerial circuit, mainly is installed in outdoor electric observing and controlling and the electric power protection product.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is theory diagram of the present utility model;
Fig. 2 is a kind of uploading data synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of power dispatching data acquisition terminal based on ZigBee of the present utility model, send to master station computer in order to the power dispatching data that gathers distribution terminal and by wireless transmission method, it comprises single-chip microcomputer, the ZigBee module, serial port drive buffer circuit and power module, described single-chip microcomputer is connected with distribution terminal by the serial port drive buffer circuit, described ZigBee module is connected with single-chip microcomputer, and be connected with master station computer by the ZigBee wireless communication mode, described power module respectively with single-chip microcomputer, the ZigBee module, the serial port drive buffer circuit is connected with distribution terminal.
Preferably, described single-chip microcomputer comprises the MSP430F5843A chip.
Preferably, described distribution terminal comprises DTU terminal, FTU terminal or TTU terminal.
The utility model mainly is divided into the two large divisions, a part is single-chip microcomputer (MSP430F5843A core board), single-chip microcomputer is as whole control center, be responsible for the running status of the processing of mass data, whole module adjustment, prevent that communication module from crashing, preventing the functions such as terminal " competition " reported data; Another part is the ZigBee module, mainly is responsible for reception and the transmission of data.
The utlity model has following characteristics:
1, the combination of single-chip microcomputer and ZigBee module has effectively prevented the generation of ZigBee module deadlock phenomenon.On hardware, single-chip microcomputer disposes the initialization of individual pin control ZigBee module.On software, a monitored data definite value administrative time TIME_VALUE is set, as ZigBee time ZiGBee_NO_DATA_TIME during without data transmission〉TIME_V, MCU jumps to the program that crashes of processing automatically, initialization serial ports and ZigBee module start the purpose that robotization recovers communication.
2, at MCU random number is set, the ingenious uploading data " competition " of having avoided guarantees that data transmission is reliable.As shown in Figure 2, the ZigBee module that is installed in each FTU terminal all need be delayed time first when sending data one random number time, random number time span is [n * 120ms, 30 * 120ms] (0≤n≤30), and this random number time is as the time of ZigBee module time-delay uploading data.When have a power failure simultaneously or when electric, the communication module of each FTU upload the data to convergent point after time-delay, be uploaded to main website by convergent point again.Can reduce to greatest extent like this probability of data " competition ", greatly improve the reliability of data transmission.
3, by the reasonable disposition resource, realized low-power consumption.On type selecting, single-chip microcomputer has selected the MSP430F5843A of super low-power consumption as master chip, but the ZigBee module adopts the low-power consumption ZigBee module of dormancy as the data transmit-receive chip.When not needing transceiving data for a long time, the MSP430F5843A chip sends a sleep signal to the ZigBee module, and the ZigBee module enters dormant state.When the needs data transmitted, the MSP430F5843A chip sent a wake-up signal to the ZigBee module, and the ZigBee module can be carried out transmitting-receiving work.Simultaneously, select low-power chip, can guarantee that after line outage the super capacitor of distribution terminal inside can provide enough electric current supply ZigBee communication module uploading datas.
