step 1, initializing a power sensor;
step 2, judging whether the first timer is interrupted, if so, executing a first task, and if not, executing a step 3;
step 3, judging whether the second timer is interrupted, if so, executing a second task, and if not, executing a step 4;
step 4, judging whether a host control command is received, if so, analyzing the control command, and performing corresponding data processing according to an analysis result;
and 5, returning the data after the data processing to the host.
In a specific embodiment, the first task is to calculate a compensated temperature value.
In one embodiment, the second task is to update the analog-to-digital converter array data.
In one embodiment, if the host control command is a write calibration data command, the power sensor receives the calibration data through a USB interface and writes the calibration data into a memory.
In a specific embodiment, if the host control command is a command for controlling an analog board, the power sensor controls the analog board through the SPI interface and sends data returned by the analog board to the host.
The data processing method of the power sensor executes different control operations by setting different interrupt operations, has various functions compared with the prior art, and can conveniently expand the functions by adopting an interrupt mode, thereby facilitating the operation of a user.
The invention also provides a power sensor data processing system, specifically, referring to fig. 2, comprising a USB communication interface, an SPI communication interface, a command parsing module, a command executing module, and a timer module, wherein the timer module is connected to the USB communication module, and is configured to enable the USB communication interface to receive a control command sent by a host when the power sensor does not receive a timing command; the USB communication interface is connected with the host and the command analysis module and used for receiving a control command sent by the host and sending the control command to the command analysis module, and the command analysis module is connected with the command execution module and used for executing the analyzed command; the command execution module is further connected with the SPI communication interface, and the SPI communication interface is connected with the simulation board and used for controlling the simulation board through the SPI interface when a control simulation board command sent by the host computer is analyzed.

The power sensor software does not perform any action in the main program, and all execution operations are completed in an interrupt, which includes three interrupts: the first timer interrupt, the second timer interrupt and the USB interrupt built in the USB communication interface, wherein the interrupt priority is changed from high to low. The first timer interrupt and the second timer interrupt belong to a timer module, and the USB interrupt belongs to a USB communication interface module. If the first timer is interrupted, the execution is preferentially carried out, and the temperature value is calculated; if the second timer interruption occurs and no first timer interruption is responded, executing the second timer interruption and updating the data in the AD array; the USB interrupt priority is lowest, namely when the interrupt of the first timer and the interrupt of the second timer do not occur at the same time, the interrupt of the USB can be responded, if the host has a command to send, the host enters a USB communication interface module, an analysis program is entered after the command is received, the operation to be executed by the host is judged according to the analysis result, and if the operation is to write calibration data, the calibration module is called to write calibration parameters into a memory; if the operation of the simulation board is controlled, the SPI module is called to control the simulation board, and if the simulation board has data to return, the USB communication interface module is called again to return the data to the host.
