Description

A kind of low-voltage ac voltage wireless monitoring device
Technical field
It the utility model is related to the experimental rig technical field measured to low-voltage alternating-current electric current signal, more particularly to one Kind low-voltage ac voltage wireless monitoring device.
Background technology
At present, it is necessary to reality when when for example power transformer is long for large electric experiment, inducting-voltage proof and shelf depreciation are tested When collection monitoring power supply, frequency conversion tank or the input of testing transformer and the curent change situation of output end because whole examination Test that process is complicated and changeable, timely Adjustment Tests thinking can be accomplished by monitoring the curent change of these positions, during avoiding experiment Occur because the event that excessively stream causes to test main equipment damage occurs.Professional is arranged when traditional mode is experiment incessantly Monitoring card is sung and readed aloud to test director, done by test director according to the count off of monitoring personnel in the clamp on amperemeter of monitoring point Go out to judge.There is the temporal hysteresis of count off in which, the test director very first time can not be made to make a response, and monitor people Member needs close-ups clamp on amperemeter data, and from high-tension testing apparatus hypotelorism, there is also certain risk.
Utility model content
The purpose of this utility model is to provide a kind of low-voltage ac voltage wireless monitoring device, can may be implemented in complicated existing The low-voltage alternating-current electric current signal for needing to gather to experiment in the experimental enviroment of field measures, and wirelessly real-time Transmission, The data of test monitoring point can be reflected to by test director with the very first time, while reduce special monitoring personnel amount, reduced Monitoring personnel and high voltage alive equipment close contact chance, improve the safety coefficient during experiment.
The technical solution adopted in the utility model is:
A kind of low-voltage ac voltage wireless monitoring device, including monitoring sampling module and processing display module, the monitoring Sampling module is connected by wireless data transmission module and processing display module communication, and the wireless data transmission module includes sampling with monitoring The main wireless data transmission module being correspondingly arranged from wireless data transmission module and with processing display module that module is correspondingly arranged;Described inspection Surveying sampling module includes high-accuracy voltage transformer and A/D converter, and described high-accuracy voltage transformer, which is fixedly installed on, to be needed Alternating current wires at sampling go out, and the input of the output end connection A/D converter of high-accuracy voltage transformer secondary side, A/D Input of the output end connection of converter from wireless data transmission module;Described processing display module include button controller, Battery/charge controller, display unit and central processing unit, the output end connection central processing of described main wireless data transmission module The input of device, the output end of the output end connection display unit of central processing unit, button controller, battery/charge controller It is connected respectively with central processing unit.
Described monitoring sampling module is multiple, then is correspondingly arranged on each monitoring sampling module from wireless data transmission module Number is also to be multiple, and the two quantity is equal;All is led to from wireless data transmission module with main wireless data transmission module using the time-division News mode is correspondingly arranged, and each has an independent ID address from wireless data transmission module, using the data with address code Frame sends data or order.
Described display unit uses LCD display.
The utility model may be implemented in the low-voltage alternating-current electric current signal gathered in complicated field test environment to experiment needs Measure, and wirelessly real-time Transmission, the data of test monitoring point can be reflected to by experiment with the very first time and be responsible for People, while special monitoring personnel amount is reduced, monitoring personnel and high voltage alive equipment close contact chance are reduced, improves examination Safety coefficient during testing.The system uses wireless transmission method, is combined with low-voltage alternating-current current measurement, realizes large-scale The real-time monitoring of electrical test mesolow ac current signal.The system uses wireless transmission method, is surveyed with low-voltage alternating-current electric current Amount is combined, and realizes the real-time monitoring of large electric experiment mesolow ac current signal.
Brief description of the drawings
Fig. 1 is the utility model schematic block circuit diagram.
Embodiment
As shown in figure 1, the utility model includes monitoring sampling module and processing display module is formed, the monitoring sampling mould Block is connected by wireless data transmission module and processing display module communication, and the wireless data transmission module is included with monitoring sampling module pair The main wireless data transmission module being correspondingly arranged from wireless data transmission module and with processing display module that should be set;Described detection sampling Module includes high-accuracy voltage transformer and A/D converter, and described high-accuracy voltage transformer, which is fixedly installed on, need to sample place Alternating current wires go out, and high-accuracy voltage transformer secondary side output end connection A/D converter input, A/D converter Output end connection from the input of wireless data transmission module;Described processing display module includes button controller, battery/fill Electric controller, display unit and central processing unit, the output end of described main wireless data transmission module connect the defeated of central processing unit Enter end, central processing unit output end connection display unit output end, button controller, battery/charge controller respectively with Central processing unit is connected.
Described monitoring sampling module is multiple, then is correspondingly arranged on each monitoring sampling module from wireless data transmission module Number is also to be multiple, and the two quantity is equal;The problem of in order to avoid co-channel interference, system use time division technique by the main nothing of system Line number transmission module is separated with any communication between wireless data transmission module by the way of the time-division, each from wireless data transmission module There is an independent ID address, data or order are sent using the data frame with address code.
The utility model sends main wireless data transmission module in specific works, by the reply data of current sampling device. Described secondary voltage is low-voltage, facilitates A/D converter to carry out analog-to-digital conversion to it.The utility model may be implemented in complicated existing The low-voltage alternating-current electric current signal for needing to gather to experiment in the experimental enviroment of field measures, and wirelessly real-time Transmission, The data of test monitoring point can be reflected to by test director with the very first time, while reduce special monitoring personnel amount, reduced Monitoring personnel and high voltage alive equipment close contact chance, improve the safety coefficient during experiment.The system uses nothing Line transmission means, it is combined with low-voltage alternating-current current measurement, realizes the reality of large electric experiment mesolow ac current signal When monitor.The system uses wireless transmission method, is combined with low-voltage alternating-current current measurement, realizes low in large electric experiment Press the real-time monitoring of ac current signal.
