Wireless data acquisition device

Abstract

The invention discloses a wireless data acquisition device. The wireless data acquisition device comprises a control circuit, a wireless communication circuit connected with the control circuit and apower-off backup circuit, wherein the power-off backup circuit comprises a power storage group, a charging switch K1, a charging switch K2, a discharging switch K3, a discharging switch K4, a first feedback detection circuit, a second feedback detection circuit, a voltage stabilizing circuit and a power supply detection circuit; the charging switch K1, the charging switch K2, the discharging switch K3 and the discharging switch K4 are sequentially connected in series, a power supply is connected to the other end, opposite to the charging switch K2, of the charging switch K1, and the other endof the switch K4 is connected with the control circuit and the wireless communication circuit after being connected with a current limiting resistor R1 in series; the node where the charging switch K1and the charging switch K2 are connected with each other is connected with the first feedback detection circuit, and the first feedback detection circuit is further connected to the control circuit;and the node where the charging switch K2 is connected with the discharging switch K3 is connected with the power storage group. The wireless data acquisition device can provide a temporary power supply for supplying power when power is suddenly cut off without a standby power supply.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a wireless data collection device. Background technique [0002] The storage of data is the most important in the information age. For example, in the process of office, if there is a sudden power failure, it will cause data loss, and if important data is lost, it will cause serious losses. Similarly, in the Internet of Things system, if there is a power outage, which leads to data loss during transmission, it may be that the various components in the Internet of Things system are running out of order, which may lead to adverse consequences. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a wireless data acquisition device, which can provide temporary power supply for power supply in case of sudden power failure without a backup power supply. [0004] In order to achieve the above objec...
