Abstract
The invention relates to a ground resistance real-time monitoring device, which comprises a switching power supply, a ZIGBEE system, an AC pulse constant current source, a collected data processing unit and a data array unit. According to the ground resistance real-time monitoring device, current emitter poles and voltage test poles adopt an anti-corrosion high-conductivity material, and are buried underground permanently; and when ground resistance change surpasses requirement, an alarm can be given, and the test data is transmitted to a client data center through a network. According to the ground resistance real-time monitoring device, during early-stage construction, the current emitter poles and the voltage test poles for testing are pre-buried in groups according to environment and geographical positions at that time, and thus collection of test data at different positions can be finished through one test. The ground resistance real-time monitoring device can reflect the ground resistance of a grounding grid comprehensively.
Description
Technical field
The present invention relates to real time monitoring field, particularly to a kind of earth resistance real-time monitoring device.
Background technology
The most many electric equipment industries have different requirements for earth resistance in all trades and professions, general
Way is the grounded screen making the earth resistance reaching requirement when construction.Earth resistance tester
Test pole, with regard to take-up after test completes, it is single measurement rather than continuously tests every day.
Measured at that time qualified after, the most not test.But it is true that earth resistance is as weather, time
And soil changes and changes.When earth resistance becomes big, normal for electric equipment uses the most not
Profit, even damages electronic equipment.
Summary of the invention
The invention solves the problems that earth resistance tester of the prior art cannot accomplish that the technology monitored in real time is asked
Topic, it is provided that a kind of earth resistance real-time monitoring device.
In order to solve above-mentioned technical problem, technical scheme is specific as follows:
A kind of earth resistance real-time monitoring device, including: Switching Power Supply, ZIGBEE system, alternating-current pulse is permanent
Stream source, gathers data processing unit, and data array unit；
Wherein: ZIGBEE system respectively with Switching Power Supply, gather data processing unit, alternating-current pulse constant-current source
It is connected；Data array unit is connected with collection data processing unit, alternating-current pulse constant-current source, grounded screen respectively；
Described grounded screen is provided with current emission pole, voltage tester pole and test pile；
Switching Power Supply, it is possible to provide electric energy；
ZIGBEE system, can produce pumping signal, processes the data signal received, and shows and launch number
According to；
Alternating-current pulse constant-current source, the pumping signal that can ZIGBEE system be produced, through amplifying, is isolated, filtering
Rear output is to data array unit；
