Embodiment
Motor fault radio alarming device, comprise housing 1 and internal circuit, internal circuit comprises transformer B, rectification circuit, direct current outgoing side at rectification circuit is provided with relay J, one end of relay J links to each other with the positive terminal of rectification circuit, the other end causes outside the housing, the normally opened contact J1-1 of relay J is serially connected with the direct current power supply loop of alerting signal transmitter F, and the negative pole end of rectification circuit also causes outside the housing.Described alerting signal transmitter is the existing product of selling on the market, can select the NC369 model of being produced by Samsung for use.This alerting signal transmitter is furnished with a plurality of mobile phones.The direct current outgoing side of rectification circuit also is connected with voltage stabilizing chip IC 1 (7824), so that being provided to subsequent conditioning circuit, galvanic current presses, also be parallel with filter capacitor C1, C2 and the power supply that connect by light emitting diode D1, resistance R 1 series connection shows branch road at the direct current outgoing side of rectification circuit, during the power supply normal power supply, light emitting diode D1 is bright.
The other end of relay J can connect multiple conducting wires and cause outside the housing.Many extension lines can make the fault alarm of this device realization to multiple motors (or plant equipment).
Be serially connected with K switch 1 on the extension line of the other end of relay J.K switch 1 is used for the elimination of alerting signal.Be in closure state under K switch 1 normal condition, when the maintenance personal receives the report for police service signal when coming in front of the warning device, cut-off switch K is to eliminate alerting signal, and motor fault resets K switch 1 after getting rid of again.
Positive pole and drawing of relay J at rectification circuit are connected with the alarm indication circuit that is formed by light emitting diode D2 and resistance R 2 serial connections between the line end.When device carried out fault alarm to multiple motors, the light emitting diode in the alarm indication circuit is the indication fault motor clearly.
Between the negative pole end of drawing line end and rectification circuit of relay J, be provided with the self-checking circuit that is in series by diode D3 and K switch 3.Press K switch 3, the current supply circuit of engage relay J, but whether the pick-up unit warning is normal.
The K switch 1 that is connected in series on the extension line of the relay J other end is ganged switch, forms the noise reduction display circuit after its another connection switch is connected with resistance R 3, light emitting diode D4.Press ganged switch K1, in the current supply circuit that disconnects relay J, another joins switch closure, and the noise reduction display circuit is connected, and realizes that noise reduction shows.
Between two output terminals of rectification circuit, also be provided with the warning pronunciation circuit that normally opened contact J1-2 and piezoelectricity singing piece M by relay J constitute.In alarm transmission device emission alerting signal, warning pronunciation circuit conducting pronunciation is to improve the warning dynamics.
