Abstract
A voltage monitoring alarm comprises a power rectifier module, a voltage monitoring module, an alarm module and a voltage display module, and is characterized in that the voltage monitoring module is respectively connected with the power rectifier module, the alarm module and the voltage display module and is further connected with an alternating current power socket. By the power rectifier module, alternating current is subjected to voltage reduction and rectification and is supplied to the voltage monitoring module and the voltage display module for the real-time monitoring of level value of the alternating current. The level valve is converted by grading at intervals of 10V and is correspondingly displayed through an LED indicator lamp. When abnormal fluctuation of voltage occurs, the alarm module sends out acoustic and optic alarming and transmits alarm data.
Description
Technical field
The utility model relates to a kind of alarm, especially a kind of monitoring voltage alarm.
Background technology
In some environment of factory and R&D institution, power source voltage is required relatively stricter; Overtension or brownout all can be to producing or equipment throw into question to use, lack a kind of surveillance equipment of supply voltage and panalarm efficiently of monitoring easily, intuitively at present.
Summary of the invention
For in order to overcome inconvenient, the problem intuitively not of monitoring supply voltage.The utility model provides a kind of monitoring voltage alarm; This monitoring voltage alarm adopts light emitting LED lamp to indicate the real-time voltage of AC power intuitively; And send sound and light alarm and alert data efficiently, all have use value widely in factory, R&D institution.
The utility model solves the technical scheme that its technical matters adopted: the monitoring voltage alarm comprises power rectifier module, voltage monitoring module, alarm module, voltage display module; It is characterized in that; The voltage monitoring module is connected with power rectifier module, alarm module, voltage display module respectively, and the power rectifier module also is connected with AC Power supply socket.The power rectifier module reduces pressure alternating current, and rectification offers the voltage monitoring module, the voltage display module is monitored the AC power level value in real time; Level value is one grade with 10V to be changed; And through the corresponding demonstration of LED light; When the electric voltage exception fluctuation occurring, carry out sound and light alarm and alert data transmission through alarm module.
The beneficial effect of the utility model is, and is simple in structure, cost is low, be prone to make, and has use value widely.
Description of drawings
Fig. 1 is the theory diagram of the utility model; Fig. 2 is the electric structural drawing of the utility model.
Embodiment
In Fig. 1, the monitoring voltage alarm comprises power rectifier module 1, voltage monitoring module 2, alarm module 3, voltage display module 4.Voltage monitoring module 2 is connected with power rectifier module 1, alarm module 3, voltage display module 4 respectively, and power rectifier module 2 is connected with AC Power supply socket 5.The power rectifier module reduces pressure alternating current, and rectification offers the voltage monitoring module, the voltage display module is monitored the AC power level value in real time; Level value is one grade with 10V to be changed; And through the corresponding demonstration of LED light; When the electric voltage exception fluctuation occurring, carry out sound and light alarm and alert data transmission through alarm module.
In Fig. 2, be provided with 12 luminotron LED in the circuit, promptly indicate the real-time level value of AC supply voltage with LED1～LED12.Alternating current 220V becomes 16V through the transformer step-down, is accomplished by D1～D4 bridge rectifier, capacitor C1～C3 filtering and IC4 voltage stabilizing again.+ 12V stabilized voltage supply is supplied with the WV of LM339.In order to detect alternating voltage, the inverting input of comparer N1～N12 is received in the input of voltage stabilizer+12V.The LED display is received the output terminal of amplifier IC1～IC3 (comparer).Because of the end of oppisite phase of all comparers links to each other with the input end of direct current stabilizer; And this input terminal voltage is proportional with AC-input voltage; Its objective is and be convenient to alternating voltage is changed sampling that the in-phase end of comparer links to each other with+12V respectively through relevant resistance for this reason.Resistance R 13～R25 in the circuit forms the resistance pressure-dividing network of reference voltage, and the voltage on node 1～12 is respectively 0.93V, 1.87V, 2.80V, 3.73V, 4.67V, 6.53V, 7.46V, 8.40V, 9.33V, 10.27V and 11.20V etc.When input voltage when 160V～270V (interchange) changes; The terminal voltage of filter capacitor C1, C2 changes about 14.3～24.1V; Zener ZD1 step-down is fixed+12V, so the no-load voltage ratio voltage of resistance R 27, R28 all is added on each comparer end of oppisite phase pin, therefore; When comparer LM339 in-phase end voltage was higher than end of oppisite phase, the corresponding LED that connects of its output just lighted.Otherwise extinguish.When input ac voltage was lower than 160V, all luminotrons extinguished; The quantity that LED lights increases by whenever adding 10V.When input voltage reaches 270V; All LED are bright entirely; Drive alarming horns through alarm module 3 simultaneously and report to the police with warning LED lamp, the closure of carrying out different contacts through the contact pattern of relay simultaneously take place corresponding high pressure or the warning message transmission of low pressure.
