Ultralow-temperature camera and ultralow-temperature starting method of the camera

Abstract

The invention discloses an ultralow-temperature IPC camera and an ultralow-temperature starting method of the camera. The ultra-low temperature IPC camera comprises a relay (1), wherein a relay switchof the relay is switched on by default; and a heating module (2), wherein the heating module (2) is connected with a power supply through a relay switch of the relay (1). According to the invention,chips and devices commonly used in the market are utilized to realize reliable starting of the equipment under the ultralow temperature condition. According to the power-on starting scheme, any function of the equipment is not influenced, the product structure is hardly changed, the development cost is greatly saved, and the product line is expanded. In other words, in the ultralow-temperature starting process, under the condition that the single-chip microcomputer and the main control chip are not started yet, the heating module is directly driven to work, and the ultralow-temperature starting performance of the camera is improved.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to an ultra-low temperature camera and a method for starting the camera at ultra-low temperature. Background technique [0002] At present, there are few models of cameras (such as ultra-low temperature IPC cameras) used in ultra-low temperature environments, and the price of such cameras is high, but the feedback from users is not high. The main reason is that during the power-on and start-up process of the existing ultra-low temperature cameras, the components used are high in cost and poor in replaceability, and are difficult to mass-produce, and the maintenance cost of equipment failure is also very expensive. [0003] At present, for cameras that support ultra-low temperature power-on, the commonly used power-on solution is controlled by a mechanical temperature control switch or using military-grade ultra-low temperature devices. For example, the ultra-low temperature IPC cam...

AI Technical Summary

Problems solved by technology

For example, the ultra-low temperature IPC camera is powered on and controlled by a mechanical temperature control switch. The logic is simple, but the cost is high. The price of the mechanical temperature control switch used is about 75 US dollars.

If military-grade ultra-low temperature devices are used, the performance is reliable, but they are large in size and high in cost, making it difficult to mass produce
