Abstract

The invention discloses an uninterruptible power supply device which is used for conducting uninterruptible power supply on a site enforcement recorder. The uninterruptible power supply device comprises a main battery module, a standby battery module and a switchover module. The main battery module is connected with the power input end of the site enforcement recorder. The standby battery module is connected with the power input end of the site enforcement recorder through the switchover module. The main battery module comprises a replaceable main battery. The standby battery module comprises a standby battery. The switchover module comprises a detection port and a switch tube, wherein the detection port is used for being connected with an intermediate electrode of the main battery so as to detect whether the main battery is pulled out. When the main battery supplies power to the site enforcement recorder, a detection result of the detection port makes the switch tube in a cut-off state to prevent the standby battery from being connected with the power input end of the site enforcement recorder; when the main battery is pulled out, the detection result of the detection port enables the switch tube to be connected so that the standby battery can be connected with the power input end of the site enforcement recorder through the switch tube to supply power to the site enforcement recorder.

Description

technical field [0001] The invention relates to uninterrupted power supply technology for law enforcement recorders, in particular to an uninterruptible power supply device for law enforcement recorders. Background technique [0002] At present, the mainstream of single police law enforcement recorder is miniaturization, function integration and light weight. However, when the above conditions are met, the capacity of the battery will be limited, causing the law enforcement personnel to encounter the situation of insufficient battery power during the execution of the task. At this time, the battery needs to be replaced, but changing the battery will cause the recorder to stop working and shut down , but some sites require uninterrupted shooting and evidence collection, changing the battery will inevitably affect the continuous monitoring requirements of law enforcement, which may lead to missing important evidence pictures. Contents of the invention [0003] The main purp...
