Abstract
The utility model relates to a network data acquirer. A power circuit of the network data acquirer supplies 3.3V power to a series data acquisition circuit, supplies 3.3V power and 2.5 V power to a network data transmission circuit and supplies 3.3V power to a main control circuit, wherein the series data acquisition circuit acquires outside data and transmits the data to the main control circuit; the main control circuit stores the data into a secure digital memory (SD) card storage circuit and transmits the data to the network data transmission circuit; the network data transmission circuit transmits the data to the outside again; an input/output interface circuit is used for acquiring or controlling an analog value and a data amount of the outside and has a controller area network (CAN) networking communication function. The network data acquirer can be applied to various distributed systems; due to a CAN bus, cascaded development of a plurality of network data acquisition modules can be realized; and the data of a plurality of remote signal sources can be acquired and transmitted according to distribution characteristics of an Ethernet.
Description
Technical field
The utility model remote data acquisition observation and control technology field relates to a kind of network data acquisition device.
Technical background
Network is as showing nowadays more and more a kind of information propagation pattern of main flow, in the extensive use of a plurality of fields.Ethernet has obtained extensive use as a kind of form of network in local area network (LAN).Because Ethernet has advantages such as easy for installation, simple in structure, cost, therefore the distributed data acquisition of many industrial circles has also adopted Ethernet as the long-distance transmissions passage.Carry out data acquisition through Ethernet and become a kind of present popular data acquisition transmission means.
Summary of the invention
The utility model provides a kind of network data acquisition device to the deficiency of prior art;
The utility model comprises power circuit, serial data collection circuit, network data transmission circuit, governor circuit, input/output interface circuit, SD card memory circuit.
The power supply that power circuit provides 3.3V for the serial data collection circuit provides 3.3V power supply and 2.5V power supply for the network data transmission circuit, and the power supply of 3.3V is provided to governor circuit; Serial data collection circuit data is to external world gathered, and data are passed to governor circuit, and governor circuit in SD card memory circuit, and is transferred to the network data transmission circuit with storage, and the network data transmission circuit goes transfer of data again to the external world; Input/output interface circuit is responsible for gathering or control outside analog quantity and data volume, and has the function of CAN group-net communication.
The utility model is compared the beneficial effect that has with background technology: the utility model is as a kind of independently network data acquisition module; Have multiple interfaces data acquisition ability and local datastore ability; Can be easy to be applied in the various distributed systems; And utilize the CAN bus can realize the cascade expansion of a plurality of network data acquisition modules, the distribution character of final ethernet network capable of using is realized the data acquisition and the transmission of a plurality of remote information source points.
