A wireless photoelectric sensor disclosed by the present invention comprises a PCB, the PCB is provided with a radio frequency emission circuit, a charging chip, a power supply management circuit and a low-voltage detection circuit which are connected with a single-chip microcomputer, the radio frequency emission circuit is wirelessly connected with a radio frequency receiver through a radio frequency antenna, and the output end of a rechargeable battery is electrically connected with the input end of the low-voltage detection circuit. The output end of the single-chip microcomputer is electrically connected with the input end of the low-voltage indicating lamp, the output end of the radio frequency antenna is electrically connected with the input end of the working indicating lamp, and the output end of the charging chip is electrically connected with the input end of the charging indicating lamp. The work indicating lamp is turned on or turned off according to whether the radio frequency emission circuit emits a signal through the radio frequency antenna or not, an initial result is displayed to an operator, and meanwhile, the sensor can work without being connected with an external fixed power supply through combination of the power supply management circuit and the rechargeable battery; therefore, the use effect of the photoelectric sensor is prevented from being affected by cable connection in the actual use process.

The embodiment of the invention discloses an offline charging method, charging equipment and a server. According to the charging device, after the device identification code of the target device is received, the device identification code is compared with the local identification code set in response to the fact that the charging device is in the off-line state, the target device is charged in response to the fact that the device identification code is located in the local identification code set, and off-line charging information is obtained and stored. Therefore, the target equipment to be charged and verified is verified based on the local identification code stored in the charging equipment, so that the function of charging the target equipment in time when the charging equipment is offline is realized, and billing is performed through the cost stage model corresponding to the actual charging time, so that the charging efficiency is improved. And meanwhile, the reliability of the local identification code set is further ensured by performing incremental synchronous updating or full-quantity synchronous updating on the locally stored equipment identification code set when the charging equipment is online.
