Embodiment
Battery electric quantity monitoring means inner structure as shown in Figure 1.Its each pin function is as follows: RBI: the input of stand-by register signal.VCC: power supply input.VSS: ground.HDQ: single line HDQ serial line interface.BAT: battery voltage detection signal input.SRN: battery charge, discharge current detect input (bearing).SRP: battery charge, discharge current detect input (just).GPIO: general I/O.The battery electric quantity monitoring means can carry out high-precision monitoring and warning to the power-supply system that is made of single lithium ion battery etc.It is connected on the pressure drop on the little resistance resistance R S of battery cathode by detection, judge that current battery is state of charging and discharging or discharge condition.Realize detecting battery electric quantity by inner " self study " process, the automatic measurement of electric weight is passed through
Calculate.Battery is every through once complete charge and discharge process, will enter one and take turns new " self study ", can upgrade the total electric weight of battery from full to sky through this " self study ", and write in the middle of the LMD register.Calculate the available battery charge relative status and write register RSOC by the numerical value that detects current available power in the NAC register,
The battery electric quantity monitoring means carries out data transmission as shown in Figure 2 by bi-directional serial interface HDQ bus and the data processing unit of a 5kbits/s.HDQ is an open-drain output pin, needs an external pull-up resistor R on HDQ during use.Its data transmission mainly adopts Asynchronous Transfer Mode, per 8 one group, low level a preceding high position after, trigger by negative edge.By the different low level retention times is set, distinguish " 0 " and " 1 " respectively, as shown in Figure 3.
Battery charging unit is connected with portable biometric function experimental facilities power backup battery by the BAT pin and is connected as shown in Figure 2, when battery electric quantity monitoring means monitoring obtains battery and enters the operating on low voltage state, promptly drive battery charging unit work and give powered battery.The battery electric quantity monitoring means began the counting cell relevant information and deposited internal register in as shown in Figure 4 this moment.Because the final available power of battery, voltage, it is influenced by single factors that essential informations such as temperature have more than, thus the battery electric quantity monitoring means comprehensively all major influence factors carry out analytical calculation and just can draw final battery correct information, its internal work flow process is as shown in Figure 5.Battery nominal available power (NAC)=battery charge-battery discharge current-temperature compensation.Up-to-date battery discharge capacity (LMD)=battery discharge current+temperature compensation-battery charge that records.Aforementioned calculation is finished automatically by battery electric quantity monitoring means inside " self study " process, does not need the user further to calculate, and is very convenient.
The monitoring system of the portable biometric function experimental facilities power backup battery that proposes according to this patent, can realize discerning the comprehensive duty of current battery automatically by inter-process, cross when cell voltage and to carry out charging work when low automatically, for portable biometric function experimental facilities normally uses, experimental data provides safeguard accurately and reliably.
