Description
Technical field
The present invention relates to a kind of electric energy meter complete machine hardware fault automatic detection device and its detection method.
Background technology
At present in electric energy meter production process, after electric energy meter complete machine is completed, upper electricity carries out hardware check, self-test content
Including power module, metering module, control module, memory module, communication module, display module, each module self-test is completed
Afterwards, if fault-free electric energy meter directly exits Auto-Sensing Mode, into normal operation mode；If ammeter has failure, ammeter will be in liquid
The brilliant corresponding error code of screen display, maintenance personal can prompt to place under repair according to code.
Existing hardware check mode is only capable of detecting power module, metering module, control for the complete machine hardware of electric energy meter
Module, memory module, communication module, display module, the hardware of electric energy meter is not accomplished that detection is completely covered.Electric energy meter
Infrared channel, RS485 passages, carrier communication interface, built-in switch action, external switch action, alarm switch action, pulse per second (PPS)
Signal, clock signal etc. can not all be detected by way of self-test.Prior art can cause the Hardware Subdivision not detected
Be diverted into next production link, hardware above problem progressively detected in later stage debugging process, if it is problematic repaired after
Need to return to the front end in detection process detect and debug again, influence product quality and production efficiency.
The content of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of electric energy meter complete machine hardware fault automatic detection device
And its detection method, it can not realize that the hardware signal of breakdown judge carries out automatic detection by self-test to electric energy meter, pass through
Where the mode of LED notifies testing staff trouble point, and the device equally can be used to electric energy meter hardware fault in maintenance personal
Carry out fast positioning and repair, all trouble points are detected and repaired in hardware detection link by testing staff, can improve electricity
The quality of production and production efficiency of energy table, reduce manpower and equipment debugging cost.
To achieve these goals, the present invention is achieved through the following technical solutions：
A kind of electric energy meter complete machine hardware fault automatic detection device, the device include power module, cpu signal processing core
Piece, signal prompt LED, SR, signal detection interface and power interface.
It is first present invention also offers a kind of electric energy meter complete machine hardware fault automatic testing method based on above-mentioned technical proposal
First will be electric on electric energy meter, electric energy meter enters self-test state, and then electric energy meter complete machine hardware fault automatic detection device is powered, should
The cpu signal process chip of detection means is by signal detection interface actively to electric energy meter infrared channel, RS485 passages, carrier wave
Passage sends data frame, and each communication port is normal if electric energy meter normal response, if the data exception or nothing that return are returned
Return and then illustrate that the passage has exception；While Air conduct measurement is carried out, cpu signal process chip can actively be examined by I/O mouths
Electric energy meter built-in switch, external switch, alarm switch, pulse per second (PPS), active output, the state of idle output are surveyed, if there is different
Often, can be prompted by signal prompt LED；Testing staff can be resetted by SR to detection means, detection
Device can re-start one-time detection after resetting to electric energy meter.
The beneficial effects of the invention are as follows：
1st, electric energy meter complete machine finds problem to be repaired in advance before debugging is entered, and it is next to reduce defective product inflow
Link, the debug time on stage body is taken, improves production efficiency.
2nd, electric energy meter complete machine detection before, hardware problem is detected in advance, reduce the later stage to defective product some
Repeatability detection work, reduces production human cost.
3rd, detection means has just carried out comprehensive hardware detection after electric energy meter is completed to it, reduces defective product
Next production link is flowed into, improves the quality of production.
Brief description of the drawings
With reference to accompanying drawing, and by reference to following detailed description, it will more easily have more complete understanding to the present invention
And be more easily understood its with the advantages of and feature, wherein：
Fig. 1 is the automatic detection device flow chart of the present invention；
Fig. 2 is the automatic detection device theory diagram of the present invention.
Embodiment
To make present disclosure more clear understandable, below in conjunction with Figure of description, present disclosure is made into one
Walk explanation.Certainly the invention is not limited in the specific embodiment, the general replacement known to those skilled in the art
