Problems solved by technology

[0003] At present, the method of connecting switching signal to the information management platform mainly depends on the wired transmission network, and its communication is mostly R485, R232 and other protocols. The engineering implementation is difficult, and the construction and operation and maintenance costs are high; It is not easy to realize massive connections; at the same time, due to the direct acquisition and transmission of signals, there is a greater possibility of false positives; the data utilization and reuse value of switch information are greatly limited

Abstract

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.
