Fig. 2 is a schematic flowchart of a method for upgrading software of a meter according to an embodiment of the present invention. The method of performing the occlusion is the processor 103 of fig. 1, as shown in fig. 2, and may include:
s201, after the processor acquires the data to be upgraded, the processor outputs a stable level signal to the power supply so that the power supply can continuously supply power.
Specifically, the process of acquiring the data to be upgraded by the processor may be downloading the data to be upgraded through a network. The method comprises the steps that firstly, data to be upgraded can be downloaded into a memory in advance, then the data to be upgraded are obtained from the memory when the processor starts upgrading, the upgrading data are utilized to upgrade software in the data to be upgraded, and in the process of upgrading executed by the processor, the processor can output a stable level signal to the power supply first, so that the power supply can continuously supply power to the metering chip. The memory may be a storage medium integrated with the processor, or may be an external memory externally connected to the processor.
The processor and the power supply can be connected through a triode, the triode can be connected to a control pin on the processor, the processor sends a stable level signal to the power supply through the control pin of the processor, the power supply can continuously supply power to the metering chip according to the stable level signal, and after the power supply continuously supplies power to the metering chip, the processor executes updating operation. The stable level signal may be high or low, and is not limited herein.
S202, after the processor finishes upgrading according to the data to be upgraded, reading a metering signal in a metering chip.
Specifically, the processor and the metering chip may be connected through a communication Interface, which may be a Serial Peripheral Interface (SPI), and is not limited herein. During the updating process of the processor, the metering chip stores the generated metering signals into a metering memory, and after the processor is upgraded, the processor starts to read the metering signals from the metering memory once, namely the metering signals recorded by the metering chip during the upgrading process.
And S203, calculating and acquiring the metering information in the upgrading process according to the metering signal.
Specifically, the processor may calculate, according to the obtained metering signal in the upgrading process, the metering information generated in the upgrading process through an operation unit therein. For an electricity meter, for example, the metering information is electricity quantity information; for a water meter, the metering information is water volume information.
Optionally, before the upgrade, the processor may record the statistical metering information once, calculate and obtain the metering information in the upgrade process after the upgrade is completed, accumulate the metering information with the previous metering information to obtain the current metering information, and record the current metering information and the current time, so as to facilitate searching in future needing to be traced.

Fig. 3 is a schematic flowchart of another method for upgrading software of a meter according to an embodiment of the present invention, and as shown in fig. 3, the method may further include:
s301, the processor closes a communication interface between the processor and the metering chip.
S302, after the processor finishes upgrading according to the data to be upgraded, a communication interface between the processor and the metering chip is opened, and a metering signal in the metering chip is read.
Optionally, after the processor acquires the data to be upgraded, the communication interface on the processor may be first turned off, or the communication interface on the metering chip may be controlled to be turned off, that is, the data transmission between the processor and the metering chip is stopped, which is not limited herein.
Correspondingly, after the software in the processor is upgraded, the closed communication interface is firstly started, after the communication interface is started, the processor firstly reads the meter calibration parameters in the metering chip, judges whether the metering chip is normal according to the meter calibration parameters, and if the metering chip is normal, reads the metering signals in the metering chip.

s401, after the processor obtains the data to be upgraded, the processor calculates and obtains the upgrading duration according to the size of the data packet to be upgraded.
For example, when the size of the downloaded program code amount in the data packet to be upgraded is 256K, the software update time period required by the processor is 50S, and when the size of the program code amount is less than 256K, the software update time period required by the corresponding processor is less than 50S, for example, 30S, 20S, and the like may be possible, that is, the size of the program code amount may be in direct proportion to the software update time period.
S402, determining the upgrade starting time according to the upgrade duration and the latest rate switching time.
The charge rate is switched according to a time point set in advance, for example, the upgrade duration calculated according to the size of the data packet to be upgraded is t, the latest charge rate switching time point is t1, and the upgrade starting time is t0, so that the upgrade starting time is t0, the upgrade starting time t0 can be determined only by meeting the condition that the time difference between the latest charge rate switching time point t1 and the upgrade starting time t0 is greater than the upgrade duration t, and the charge rate switching can be avoided according to the upgrade starting time calculated by the condition, thereby ensuring the charging accuracy.
S403, the processor calls the data to be upgraded to start upgrading at the upgrading starting time.
Specifically, the processor sets the calculated upgrade starting time in the meter in advance, and can call the data to be upgraded to start upgrading through a timing command.
