Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model elevator intercommunication power supply.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical scheme of the utility model embodiment.
As shown in Figure 1, a kind of elevator intercommunication power supply that the utility model discloses, comprise civil power input circuit, discharge and recharge change-over circuit, storage battery, load output circuit and monitoring, alarming circuit, it is direct current (DC) 12V power supply that civil power input circuit will exchange (AC) 220V Power convert in the normal situation of civil power.The output termination discharge and recharge change-over circuit of civil power input circuit and monitoring, alarming circuit, power for the DC12V power supply after conversion is exported to them.
The output of discharge and recharge change-over circuit is connected with storage battery with load output circuit, and and is be bi-directionally connected between storage battery.Discharge and recharge change-over circuit is used for the direct current after being converted by civil power to load supplying, simultaneously to charge in batteries.
Load output circuit comprises intercom output, alarm bell exports and emergency light exports, and namely these load supplyings given by civil power or storage battery.The output of load output circuit is also connected with monitoring, alarming circuit, monitors for output signal being transferred to monitoring, alarming circuit.
The output of storage battery is also connected with monitoring, alarming circuit, after civil power power-off, switches to storage battery to external loading and monitoring, alarming circuit supply.
Monitoring, alarming circuit is for gathering the input of civil power input circuit, the output of load output circuit and battery tension, current signal but be not limited to these signals, and judge power work state, Timeliness coverage fault is also reported to the police.In the present embodiment, monitoring, alarming circuit comprise signal gathering unit, voltage and discharge time detecting unit and alarm unit, signal gathering unit for gather the input signal of civil power input circuit, the output signal of load output circuit, the voltage signal of storage battery and current signal to voltage and discharge time detecting unit; Voltage and discharge time detecting unit be used for carrying out detections analysis according to these signals of receiving, and output alarm signal is to alarm unit; Alarm unit is used for sending alarm in time, and reminding user to replace battery or in time cut-out are emergent to be exported.
Particularly, the principle of the utility model charge and discharge control and detection alarm is: after power supply energising, first carry out initialization, and judge city's electricity condition.As civil power is in normal condition, then the direct current DC12V after being converted by civil power exports, and judges simultaneously, as battery underfill, then charge to storage battery to battery tension; After battery is full of, disconnect charging, detect battery tension, if cell voltage is still higher than 12V, then battery is normal, if cell voltage is lower than 12V, then judges battery malfunction, and alarm changes battery.When after civil power power-off, automatically switch to storage battery power supply, if be greater than 2 hours discharge time or battery tension lower than 10.5V time, then cut off emergent output, protection storage battery prevents overdischarge.
Technology contents of the present utility model and technical characteristic have disclosed as above; but those of ordinary skill in the art still may do all replacement and the modification that do not deviate from the utility model spirit based on teaching of the present utility model and announcement; therefore; the utility model protection range should be not limited to the content that embodiment discloses; and various do not deviate from replacement of the present utility model and modification should be comprised, and contained by present patent application claim.
