Numeral and the corresponding component title represented by letter in figure:
100. single-chip microcomputers, 200. electric currents assist earth polar, 300. grounded screens, and 400. voltages assist earth polar, 500. warning devices, and 110. electric currents auxiliarily machine connect wire, 120. the earth, and 130. voltages assist earth polar to connect wire, 140. grounding connection wires.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to shown in Fig. 1, a kind of stake resistance on-Line Monitor Device provided in figure, comprising: single-chip microcomputer 100, electric current assist earth polar 200, voltage assists earth polar 400, grounding connection wire 140 and warning device 500.
Single-chip microcomputer 100 can select the single-chip microcomputer 100 of different model according to actual conditions, because single-chip microcomputer 100 has been the technology that these those skilled in the art understand, and then no longer repeated at this, in observation process, first-selected send current signal by single-chip microcomputer 100, and electric current assists earth polar to connect wire 110 by the electric current being embedded in the earth 120 inside to be transferred to electric current and to assist on earth polar 200.
Electric current assists earth polar 200 by current delivery on the earth 120, electric current is transferred to in the grounded screens 300 that are connected of the earth 120 by the earth 120 further, last electric current transmits back on single-chip microcomputer 100, further by single-chip microcomputer 100 measuring circuit current value by the grounding connection wire 140 connecting grounded screen 300 and single-chip microcomputer 100.
Voltage is assisted and is connected with voltage between earth polar 400 with single-chip microcomputer 100 and assists earth polar to be connected wire 130, thus make single-chip microcomputer 100, voltage assist earth polar to connect wire 130, voltage auxiliarily machine 400, the earth 120, grounded screen 300 and grounding connection wire 140 constitute a closed loop, further by single-chip microcomputer 100 measuring voltage value.
