Description

A power inspection device

technical field

The invention relates to a wireless device, in particular to a power inspection device.

Background technique

In the power inspection, the inspection instrument is used more and more widely. The inspector only needs to scan the barcode on the surface of the inspection power equipment, and the barcode scanning device decodes the barcode to obtain the information of the power equipment and realize the record, instead of the traditional manual Record. Manual recording has a large bit error rate, but the use of barcodes will greatly reduce the bit error rate. The inspection instrument needs to capture at least one frame of images containing decodable marks, then decode them, and transmit the decoded data to the host computer. The upper computer can be a server, a smart phone, a tablet computer, etc. In the prior art, when two devices (inspector and host computer) are connected wirelessly, the Bluetooth marker device will constantly judge the connection status between the two devices. When the connection is unstable due to distance or signal strength attenuation, the Bluetooth The marking device will judge the threshold value of the strength of the transmission signal. When the threshold value is lower than the set value, the transmission power of the power inspection device will be adjusted, and the communication between the two devices will be maintained by increasing the transmission power. Increasing the transmission power will inevitably lead to an increase in the power consumption of the inspection instrument. If the transmission power is increased, but there is still no effective connection between the two devices, in this case, the bit error rate of data transmission will increase, which will easily lead to data errors or loss. . Simply numbering and verifying the data sequence will lead to frequent invalid retransmissions. Multiple retransmissions may not ensure the integrity of the data, the reliability of wireless transmission cannot be guaranteed, and the bit error rate of signal transmission is high. . If the transmission power is increased for the bluetooth marking device, the working time of the inspection instrument will be shortened.
