Description
Technical field
The utility model relates to the electric-examination measuring technology, especially a kind of cabinet air-conditioner mainboard relay automatic testing equipment.
Background technology
What the control of cabinet air-conditioner mainboard load was at present adopted is that relay is controlled; And the conversion performance of relay is most important; Connecting behind the neon lamp through naked eyes of detect adopting in process of production judges that light on and off judge, just because the neon lamp service voltage can be normally luminous after greater than AC80V, when existing foreign matter and adhesive bad between the relay contact; The voltage that relay is exported will not reach normal pick-up voltage AC220V; And this voltage can make neon lamp normally luminous, so adhesive is bad flows out inside and outside the factory because of the relay contact foreign matter causes often, causes serious hidden danger of quality after sale.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure; Can carry out the real-time voltage detection to the voltage to contact output after the relay adhesive; Detected relay output voltage and reference power supply voltage compare; The relay output voltage when the minimum voltage value is set, output alarm signal, thus realize the cabinet air-conditioner mainboard relay automatic testing equipment that detects automatically.
The technical scheme that purpose adopts of the utility model is; Comprise and detect voltage commutation filtering circuit, photoelectricity isolated data transmission circuit, reference voltage signal sample circuit, power supply, LCD, warning circuit, voltage collection circuit, data processing and converter; Its data processing is connected the output terminal of power supply, the output terminal that P2.2 connects LCD, the output terminal that P2.4 connects warning circuit with converter IO mouth VCC; It detects the P1.0 end that voltage commutation filtering circuit output terminal connects voltage collection circuit; Reference voltage signal sample circuit output terminal connects the P1.1 end of voltage collection circuit; The serial ports P3.0 end of voltage collection circuit is connected photoelectricity isolated data transmission circuit two input ends respectively with the P3.1 end, and photoelectricity isolated data transmission circuit two output terminals connect the serial ports P3.1 end and the P3.0 end of data processing and converter respectively.
The cabinet air-conditioner mainboard is divided on circuit structure thermally and cold ground; And pick-up unit relay is driven with the collection of relay output voltage on will inevitably cause thermally and use with coldly; And thermally with will cause air-conditioning mainboard and pick-up unit to burn out after using with coldly; Even the potential safety hazard that exists operating personnel to get an electric shock, so must will be thermally with carry out strict isolation coldly.Can carry out simultaneously the sampling and the detection of various data again; So on this pick-up unit, adopted photoelectric switching circuit; Let the relay current detection section work in thermally, work in coldly and drive with data processing section, between carry out communication of data and conversion through photoelectric switching circuit.
When the utility model device detects; Connect the AC220V power supply at first for the air-conditioning mainboard; Let mainboard be in normal operating conditions; Send relay drive signal subsequently and let relay K adhesive conducting, relay output end voltage through detect the voltage commutation filtering circuit with the voltage signal rectifying and wave-filtering after, send into voltage collection circuit mouth P1.0 and carry out analog to digital conversion.From the reference voltage signal sample circuit, get reference signal simultaneously; And the relay voltage data that is detected and the reference voltage data serial ports P3.1 end from voltage collection circuit sent; Isolate the receiving end P3.0 that the transmission data circuit is transferred to data processing and converter through photoelectricity; When data processing and converter receive the data that voltage collection circuit transmits, the data that received are carried out integrated logic computing and processing by voltage collection circuit, as when detecting the relay output voltage less than the preset minimum voltage value of reference voltage; Output alarm signal, and suspend and detect; Just often give a relay drive signal when detection and detect next group relay, cycle detection detects the defeated qualified signal in the back that finishes until all relays repeatedly.Magnitude of voltage that is detected and step all show on LCDs, so that carry out man-machine conversation.
The load-relay that this pick-up unit can be used for being exported on the cabinet air-conditioner mainboard detects automatically; And detection is the magnitude of voltage of output terminal; But not switching value; So adopt this pick-up unit will effectively screen functional translation exceptions such as relay electrical equipment electric shock foreign matter, adhesive be bad, improve robotization to detect detection level, to reach the mass property of measured relay.
The utlity model has simple and compact for structurely, easy to use, the mass property that detection speed is fast, can in time react measured relay is enhanced productivity characteristics such as minimizing personnel.
