Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the present invention, and be not used in qualification the present invention.
Describe the present invention below with reference to the accompanying drawings in detail.
Fig. 2 is the flow chart according to the indicating means of extra battery power shortage state of the present invention.
With reference to Fig. 2, a kind of indicating means of extra battery power shortage state is provided, it comprises:
Step S202 starts reserve battery;
Step S204 monitors reserve battery; And
Step S206 when monitoring extra battery power shortage, carries out the short of electricity indication.
Step S204 also comprises: whether the output voltage of monitoring reserve battery reaches threshold value.
If the output voltage of reserve battery does not reach threshold value, then judge extra battery power shortage.
Threshold value is the required voltage of load.
Carrying out short of electricity indication comprises: the display light signal, send the combination of any one or they in the alarm signal to the alarm chip.
Reserve battery is a disposable lithium cell.
Fig. 3 is the block diagram according to the indicating device of extra battery power shortage state of the present invention.
With reference to Fig. 3, a kind of indicating device of reserve battery 301 power shortage states is provided, it comprises:
Start module 302, be used to start reserve battery 301;
Monitoring modular 303 is used for reserve battery 301 is monitored; And
Short of electricity indicating module 304 is used for when monitoring modular 303 monitors reserve battery 301 shorts of electricity, carries out the short of electricity indication.
Whether the output voltage of monitoring modular 303 monitoring reserve batteries 301 reaches threshold value.
If the output voltage of reserve battery 301 does not reach threshold value, then monitoring modular 303 is judged extra battery power shortage.
Threshold value can be the required voltage of load.
Short of electricity indication can comprise: the combination of light signal, any one or they in the alarm signal that the alarm chip sends.
A design power supply supervisory circuit (as shown in Figure 4) between original standby disposable lithium cell and load, power supply supervisory circuit is monitored the front end cell voltage, if voltage does not reach the load necessary requirement, produces alarm signal.Alarm signal can be that the LED lamp is bright, can give the certain chip alarm signal, but also the both has.
Its specific implementation step:
1. startup mains switch, power supply begins to power on.
2. power control circuit is monitored stand-by power supply (for example, disposable lithium cell) and is isolated, and reaches the load required voltage at the output voltage of the standby disposable battery of front end, does not alarm.If the output voltage at battery does not reach the load required voltage, send alarm signal.
3. when the control personnel of system found the stand-by power supply short of electricity, in time Backup Data was to other places, as printing, send data to other standby systems.Under the situation of system's power down while stand-by power supply also short of electricity, avoided causing system data to lose.
Adopt method provided by the invention, the reliability of standby disposable lithium cell indication power shortage state significantly improves, and its application for disposable battery simultaneously is very practical.
From the actual effect aspect, if the system power down also situation of short of electricity of stand-by power supply has simultaneously adopted before the inventive method, the phenomenon that system data is lost can appear; And after employing the present invention, in a single day the situation of electric weight deficiency appears in reserve battery, can in time notify the staff to take measures, and system's power down data so just seldom can occur does not have the situation of backup in time yet.
By power supply supervisory circuit monitoring with isolate standby disposable lithium cell and load, convenient and reasonable operation like this, and the fine whether problem of short of electricity of standby disposable lithium cell of indicating that solved.
Fig. 4 is the block diagram according to backup battery voltage check circuit of the present invention.
Fig. 5 is the flow chart according to the detection extra battery power shortage state of the embodiment of the invention, detects the whether short of electricity of standby disposable battery, and concrete implementation step all comprises wherein.With the example of SDH optical transmission device veneer, specifically introduce implementing procedure of the present invention below.
The used power supply of veneer is the 3.3V primary power cource, standby disposable lithium cell is given the CPU real-time clock in primary power cource outage back and is used to preserve the ASRAM chip power supply of database data, make real time clock circuit keep normal operation, data of database remains in the chip always.Power supply supervisory circuit on this example veneer, what adopt is that uP supply voltage monitoring chip MAX704TCSA (back is called for short 704) is as detection chip, be used for detecting the voltage of battery, the positive pole of battery is linked into 704 chip PFI pins as the input voltage signal of power sense circuit, 704 chip PFO pins meet LED and CPU (report and alarm) as the output of testing circuit.When the voltage of one-board power supply reaches the operating voltage of 704 chips, the action such as do not reset of 704 chip operate as normal, at this moment, if the voltage of PFI pin does not reach defined threshold, 704 PFO pin level step-down produces alarm.If alarm, staff in time Backup Data database data avoids loss of data in PC.
1. check whether standby disposable battery has been welded on the veneer;
2. startup mains switch, the front end power supply begins to power on;
3.704 the standby disposable lithium cell voltage of chip detection;
4. if its voltage reaches threshold value, then veneer normally moves;
5., then produce alarm (LED lamp and report the CPU alarm), veneer operation simultaneously if voltage does not reach threshold value.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
