Problems solved by technology

[0004] However, the monitoring will be interrupted during the restart process. If the temperature cannot be lowered continuously, the device will restart repeatedly. At this time, the camera monitoring function basically disappears, which reduces the reliability of the camera.
And not all Socs have the function of over-temperature protection, the existing technology is not universal

Abstract

The embodiment of the invention discloses a camera over-temperature protection method and device, a storage medium and electronic equipment. The method comprises the following steps: determining the current junction temperature of the camera system-on-chip and the currently executed initial service; determining a corresponding environment temperature interval when the camera system-on-chip of the current junction temperature executes the initial service in the abnormal working state, and taking the environment temperature interval as a first environment temperature interval; determining a second environment temperature interval to which the first environment temperature interval belongs and a corresponding target service from a preset environment temperature interval; and controlling the camera system-on-chip, and switching the initial service to a target service corresponding to the second environment temperature interval for service processing. According to the technical scheme, under the condition that equipment is not restarted, over-temperature protection of the camera can be achieved by reducing services, and over-temperature protection of various cameras can be achieved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of camera over-temperature protection, and in particular, to a camera over-temperature protection method, device, storage medium, and electronic equipment. Background technique [0002] At present, the product specifications of outdoor cameras used in more complex environments usually need to meet the working environment of -40-70°C, and the specifications of indoor products need to meet the working environment of -20°C-50°C. Some products, such as small conch machines and small plastic cylinder machines, are limited by structure and cost, and the specifications cannot meet the above-mentioned working environment or the products are at the critical value of the above-mentioned specifications. When the ambient temperature deteriorates slightly, such products are extremely prone to overheating problems. [0003] Under normal circumstances, the self-protection of the chip is realized...
