Abstract
A multi communication port multi protocol intelligent traffic collection device of the utility modelcomprises a supervisory computer, a microprocessor, a data memory RAM and a bus, which is characterized in that the microprocessor is a microprocessor MCU with an FLASH memory, is connected with the analog switch through at least two bus interfaces, and is connected with the supervisory computer through the USB interface. The major feature of the multi protocol intelligent traffic collection device can communicate with and collect data of the terminal equipment with multi different protocols, which can release the supervisory computer from the busy communication work; another advantage is that the data transmission of the whole system is highly effective and reliable as a result of that the upload of the data is finished through the USB bus.
Description
Technical field
Patent of the present invention belongs to electric automatization control device, relates to a kind of many communication ports multi-protocols intelligence communication harvester, promptly a kind of device that can carry out data acquisition to a plurality of data terminal equipment with different communication protocol.
Technical background
In the Computerized monitor system of transformer station and industry spot, gather many remote scene data by communication mode.Communication, the supervisory control and data aquisition system of electric system at present are installation data analog input cards in PC or industrial computer, and as A/D card and 422,485 cards, at this moment PC and terminal unit are finished the transmission of order and collection in worksite data by serial communication.Along with new equipment, The application of new technique, its defective becomes increasingly conspicuous, and as trouble is installed, work efficiency is lower, costs an arm and a leg; Limited by computer slot quantity, address, interrupt resources, adaptability and poor expandability; In the strong test site of some electromagnetic interference (EMI), can't do electromagnetic screen to it specially, cause the data distortion gathered, or the like.
Summary of the invention
At above problem, the purpose of this utility model provides a kind of many communication ports multi-protocols intelligence communication harvester, it can intelligently, high efficient and reliable be finished with the data acquisition of a plurality of terminal units, communicate by letter and the data conversion storage task, computing machine is freed from heavy collection, communication work, thereby improve the efficient of computer acquisition and supervisory system greatly, and have good and economic.
Many communication ports multi-protocols intelligence communication harvester, comprise: host computer, microprocessor, data-carrier store RAM and bus, it is characterized in that microprocessor is the microprocessor MCU with FLASH storer, microprocessor MCU connects analog switch through two kinds of bus interface at least, and microprocessor MCU connects host computer through USB interface.
Aforesaid harvester is characterized in that being connected with the isolation optocoupler between bus interface and the microprocessor MCU.
The innovative point of our many communication ports multi-protocols intelligence communication collector is:
1, utilized analog switch to switch communication mode, can communicate by letter and data acquisition with the intelligent terminal of multiple different agreement (as PLC etc.).
2, be connected with host computer by USB, both inserted both usefulness, be uploaded to PC together after the collected collector of data, do not take the cpu resource of host computer during the collection, the transmission speed of USB is also very fast;
Description of drawings
Fig. 1 is the hardware circuit diagram of embodiment of the present utility model.
Fig. 2 is the bus interface among Fig. 1 and the connection layout of analog switch.
Concrete embodiment
Describe in detail below in conjunction with accompanying drawing:
Microprocessor MCU adopts the single-chip microcomputer C8051F017 of CYGNAL company, and its FLASH storer has the reprogramming ability in system, allows on-the-spot 8051 firmwares that upgrade.C8051F017 connects host computer by USB interface, compares with preceding agreement when being used for from the host computer to MCU loading agreement and MCU realizes uploading of data by USB (universal serial bus) (USB), the PDIUSBD12 of USB interface chip employing PHILIPS company.The photoelectricity of MCU and the next devices communicating is isolated employing optocoupler 6N137, is used to isolate extraneous interference.Because the bus that industrial circle is commonly used has RS232, RS485 etc., RS232, RS485 control circuit select for use MAX232, MAX485 to realize the conversion of level as receiver transmitter; Interface selected control circuit is selected analog switch DG384 for use, MAX232, MAX485 are connected to analog switch DG384, switch between bus interface MAX232, MAX485 by analog switch DG384, analog switch DG384 realizes different communication mode with external device with an interface.
The data which kind of terminal device host computer gathers according to the needs decision of monitoring are loaded on the firmware program of MCU with the communication protocol of this equipment, and then whole data acquisition, temporary and upload procedure need not the control of host computer all by the MCU independent processing.Need to comprise communication mode to terminal, baud rate etc. in the firmware program that loads, the bus that MCU was set before data acquisition to be controlling DG384, thereby can select correct mode and terminal communication.
Consider the processing speed advantage of host computer, the work of storage, data parsing and the data storage of multi-protocols is transferred to it finish.After the data of gathering reached host computer via PDIUSBD12, customer service routine call corresponding protocol analysis program promptly was decoded as uniform data format to the data of the different-format that receives by corresponding protocol.Through verification, if the wrong terminal of then notifying of data retransmits; If the errorless clear data that obtains after then will resolving deposits the internal memory of appointment in, and backups to the customer service routine call of respective document for other.
Can communicate the terminal device of a plurality of different agreements with data acquisition is the greatest feature of these multi-protocols intelligence communication harvester, and host computer is freed from loaded down with trivial details communication work; Another big advantage is, uploading by usb bus of data finished, and makes that the data transmission of total system is efficient, reliable.
Claims (2)
1, many communication ports multi-protocols intelligence communication harvester, comprise: host computer, microprocessor, data-carrier store RAM and bus, it is characterized in that microprocessor is the microprocessor MCU with FLASH storer, microprocessor MCU connects analog switch through two kinds of bus interface at least, and microprocessor MCU connects host computer through USB interface.
2, harvester as claimed in claim 1 is characterized in that being connected with the isolation optocoupler between bus interface and the microprocessor MCU.
