The invention discloses a switching value signal monitoring device based on wireless transmission. The device comprises a power module, a data analysis module, a power monitoring module, a switching value signal monitoring module and a replaceable wireless transmission module, wherein the replaceable wireless transmission module is connected with a cloud server, and an awakening module is connected between the switching value signal monitoring module and the data analysis module. The invention furthermore discloses a switching value signal monitoring method based on wireless transmission. Themethod comprises the steps that when the switching value signal monitoring module detects a switching value signal change, the data analysis module is awakened through the awakening module; the data analysis module acquires a switching value signal from the switching value signal monitoring module, signal sampling is performed by multiple times, the replaceable wireless transmission module is awakened through judgment, and a power feature value and the switching value signal are reported to the cloud server through the replaceable wireless transmission module. According to the switching valuesignal monitoring device and method, through low-power-consumption design and a front misreport analysis algorithm, far-distance wireless transmission of switching value signal data is realized, and the misreport rate is effectively lowered.

The present invention discloses a calibration method, device, equipment, and computer-readable storage medium for a coherent optical module. The method includes: obtaining a first curve relationship and a second curve relationship; the first curve relationship indicates that the coherent optical module corresponds to a receiving end The relationship between the power gain reported voltage and the optical power of the receiving end within the optical power range; the second curve relationship represents the relationship between the coherent optical module corresponding to the target setting voltage within the optical power range of the receiving end and the optical power of the receiving end; based on the first curve relationship and the second The curve relationship determines the first optical power; the first optical power is used to divide the receiving end optical power range into two ranges; the calibration method of the coherent optical module is determined based on the first optical power; the calibration method includes: in the coherent optical module When the receiving end optical power is in the first range, use the first curve relationship to calibrate the coherent optical module; when the receiving end optical power of the coherent optical module is in the second range, use the second curve relationship to calibrate the coherent optical module The module is calibrated.
