Embodiment
Referring to figs. 1 through Fig. 4, the utility model intellectual water meter embodiment is described further.
As shown in Figure 2, a kind of double-power intelligent water meter, comprise watchcase 1, the bonnet 2 of described watchcase 1 has working battery mount pad 3, emergency cell mount pad 4 is offered in the inner side of working battery mount pad 3, under normal circumstances, emergency cell is hidden in the back side of working battery relative to watchcase 1 bonnet 2.Design is only after taking-up working battery so like this, can take out emergency cell.Ensure that emergency cell can not arbitrarily get loose.
As shown in Figure 3, watchcase 1 inside of the present embodiment has dual power supply emergency set 5, by circuit integrated in dual power supply emergency set 5, with the electricity of follow-up work battery, and when working battery electricity is not enough, produces light prompt.When working battery electricity is lower than minimum critical point, produces and start emergency cell.
Further, as shown in Figure 1, the present embodiment has the portable lamp and emergency light that are arranged on watchcase 1 rear portion.Its object is to, by the duty of portable lamp instruction working battery, by the duty of emergency light instruction emergency light.Remind the intellectual water meter internal electrical amount concrete condition of staff's the present embodiment.
As shown in Figure 4, in the dual power supply emergency set 5 of the present embodiment, integrated circuit comprises
Electric power detection unit, is coupled to the positive electrode seat of described working battery mount pad 3, exports battery measurement signal with the dump energy according to working battery; Work Tip element, is coupled to described electric power detection unit, to carry out battery electric quantity prompting according to described battery measurement signal; Emergency unit 53, is coupled to described electric power detection unit, to enable the emergency cell in described emergency cell mount pad 4 according to the dump energy of working battery.
Particularly, electric power detection unit comprises resistance R1, and resistance R1 one end is coupled in working power X1 positive pole, the other end by ground connection after resistance R2, wherein also parallel in one end of the resistance R1 coupling resistance R2 negative electrode being connected to voltage stabilizing diode D1.By above-mentioned design at the dump energy of working power X1 after resistance R1 and resistance R2 dividing potential drop, input to the negative electrode of voltage stabilizing diode D1, according to the breakdown characteristics of voltage stabilizing diode D1, when the voltage only having its negative electrode to input is higher than certain value, the anode of voltage stabilizing diode D1 just has stable output; So, when the dump energy of working battery X1 is higher than predetermined value, voltage stabilizing diode D1 is breakdown, and its anode exports high level, otherwise then voltage stabilizing diode D1 does not have breakdown, its anode output low level; 53, emergency unit 53.
In addition, resistance R2 can be potentiometer.Potentiometer be there are three exits, resistive element that resistance can regulate by certain Changing Pattern.Potentiometer is made up of resistive element and moveable brush usually.When brush moves along resistive element, namely obtain the resistance value or voltage that become certain relation with displacement at output terminal.So by making brush move on resistance, can the resistance of regulating resistance R2.
Such purpose of design is, after the voltage breakdown of voltage stabilizing diode D1 is determined, can select to drop to when lithium battery 3 electricity the battery measurement signal which kind of degree carrys out output low level by the resistance of regulating resistance R2.
Particularly, description below is made in this enforcement, and suppose that resistance R1 is A ohm, resistance R2 is potentiometer, and simultaneously voltage stabilizing diode D1 needs to lie prostrate above voltage at its negative electrode input C and can puncture voltage stabilizing diode D1, and the lithium battery 3 electricity upper limit is 5V.
Now regulating resistance R2 is B ohm, if now the negative electrode input of voltage stabilizing diode D1 is C volt just.So the electricity of lithium battery 3 is [(A+B)/B] * C.Therefore by regulating the numerical values recited of B, the startup prompt facility when what value the electricity of lithium battery 3 reach can be changed.
