[0002] In the past, the heating video wireless alarm device at the connection point of the cable head can send an "alarm signal of abnormal heating" to the equipment maintenance personnel in time when there is an abnormal heating at the connection point, and the corresponding heating point video cannot be seen.
Maintenance personnel should immediately go to the fault site for inspection, analysis and processing when the site conditions are not clear. Sometimes maintenance personnel will not bring some professional maintenance tools because they do not know the specific conditions of the site, which has a certain degree of blindness.

The invention discloses a wireless alarm system against heating of a power cable head connection point. The wireless alarm system comprises a temperature measuring device, a camera device, a processing device, a wireless emission module, a wireless reception module, a control display device and an alarm device, wherein the temperature measuring device is arranged at the cable head connection point, the signal output end of the temperature measuring device is connected to the processing device, a lens of the camera device is aligned to the cable head connection point, the signal output end of the processing device is connected with the camera device and the wireless emission module via a drive circuit, and the wireless reception module transmits received data to the control display device and the alarm device. When heating or other abnormal condition occurs in the cable head connection point, a corresponding video circuit can be timely started to transmit video signals, a monitoring staff can notify maintenance staff of relatively detailed and accurate fault condition via video display, and convenience is provided for maintenance and first-aid repair.
Description
technical field [0001] The invention relates to a wireless alarm system, in particular to a wireless alarm system for heating at the connection point of a power cable head. Background technique [0002] In the past, the heating video wireless alarm device at the connection point of the cable head can send an "alarm signal of abnormal heating" to the equipment maintenance personnel in time when the abnormal heating occurs at the connection point, and the corresponding hot spot video cannot be seen. Maintenance personnel should immediately go to the fault site for inspection, analysis and processing when the site conditions are not clear. Sometimes maintenance personnel will not bring some professional maintenance tools because they do not know the specific conditions of the site, which has a certain degree of blindness. Contents of the invention [0003] The purpose of the present invention is to provide a wireless alarm system for heating at the connection point of th...
