Description
Technical field
The utility model relates to the interface arrangement that collection in worksite curtage signal is measured, the used interface arrangement of image data when particularly relating to the measurement that laboratory and industry spot carry out electric current, voltage, thermopair, platinum resistance and foil gauge etc.
Background technology
At present, IMP data acquisition board (35951C) has 20 tunnel analog input channels, each passage can be set at the metering system of unlike signal type (as voltage or electric current etc.) and different range abilities (as 0-10V or 0-20mA) with software respectively, so just might field position is concentrated relatively, 20 different measuring point signals (no matter being voltage, electric current or the output of other transmitter) of kind are received same and are measured plate.Make things convenient for the data acquisition of industry spot.This data acquisition board is simple and practical to the DC voltage data acquisition, directly signal is inserted unitor (35953A) and gets final product.But, for the measurement of DC current, need and connect suitable sample resistance at the inner input end of unitor, be not equal to 100 Ω as its resistance, the current value of then measuring should convert in main frame, and its conversion relation is as follows:
Need install and remove when inserting current signal with regard to needing like this to the resistance in the unitor at every turn, cause high-accuracy resistance plug-in unit to fracture easily and the inner measuring point of connector between short circuit, thereby cause high-accuracy resistance and signal unitor (35953A) to damage.
The utility model content
The purpose of this utility model provides a kind of scene data acquisition system (DAS) interface arrangement easy to use, when gathering current signal, need not the high-accuracy resistance in the unitor is carried out dismounting, thereby protects high-accuracy resistance and unitor not to be destroyed.
This novel purpose is achieved in that a kind of data acquisition system (DAS) interface arrangement, comprise the IMP data acquisition board 35951C and the unitor 35953A that are coupled to each other, also have 20 pairs of thermal technology's connection terminals and double self-locking plug-in unit be installed on the printed circuit board, and 20 docking points of thermal technology's connection terminal respectively with the corresponding electrical connection of a socket mouth of double self-locking plug-in unit; 20 pair of wire connection terminals in the described unitor 35953A respectively with the corresponding electrical connection of another socket mouth of double self-locking plug-in unit, and be in series with a high-accuracy resistance R on two contacts of the every pair of wire connection terminals of this unitor.
Damage for fear of existing high-accuracy resistance and signal unitor (35953A).At IMP data acquisition board (35951C) enclosure designs one socket circuit, inner high-accuracy resistance is forever returned fixes on the signal unitor terminal, outside carry out on-the-spot industrial electric current signal sampling with the 20 standard thermal technology's connection terminals to (40 contacts), the centre 40 faller gill lines that use a computer carry out internal-external conversion connection.
The beneficial effects of the utility model are, can not take off unitor (35953A) bonnet and do not damage under the situation of high-accuracy resistance, carry out the current sample of industry spot easily, and this interface circuit is simple in structure, and is convenient and practical.
Description of drawings
Fig. 1 is a circuit structure diagram of the present utility model.
