The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The integrated circuit of the single lens reflex camera realizes the intrinsic safety explosion-proof function of the circuit through the intrinsic safety type circuit energy limiting technology under the condition that the reliability and the stability of the camera are not influenced, so as to achieve the intrinsic safety explosion-proof level. Specifically, the part needs to analyze the internal circuit of the camera block by block, arrange a detailed schematic diagram, analyze each module circuit according to a drawing, figure out a power supply structure topological diagram and a signal routing diagram, analyze the path of the battery voltage converted by each chip according to the power supply topology, check whether potential sparks and the risk of exceeding the temperature rise are existed one by one according to the standard terms of national standards 3836.1 and 3836.4, and limit the energy of the power supply path at risk, so as to achieve the purpose of effectively controlling the energy to exceed the standard and ignite the combustible gas; the signal trend graph needs to analyze whether the energy exceeding risk exists or not according to the transmission direction and the signal size of the signal and whether the energy exceeding risk exists or not is transmitted to other functional module areas, so that whether energy limiting processing is carried out or not is determined. The power supply topology and the energy limiting processing of signals need to be comprehensively considered so as to achieve the final aim of limiting energy and not influencing the normal circuit function.

After the power supply topology and the signal trend analyzed in the previous step are combined and limited, the energy storage and potential release energy of each power supply module part needs to be counted, and the dangerous power supply circuit module is subjected to a mode of reducing the specification of an energy storage element, so that the energy storage and energy release risks are reduced, and the intrinsic safety explosion-proof level is achieved.

For the in-camera driving circuit, it is divided into a micro motor portion and a flash portion.

For a micro-motor driving circuit, firstly, determining parameters, a power supply and a driving mode of a driving motor, and carrying out energy limitation or type reselection according to a specific mode so as to reduce energy storage and block a transmission path, realize an intrinsic safety explosion-proof function and achieve an intrinsic safety explosion-proof grade;

the flash lamp part drive belongs to an energy storage part with a larger size, and the stored energy reaches the instant energy release through a high exposure mode to provide a high-brightness shooting effect. The direct relation between the brightness and related devices is achieved, the direct reduction of specifications is difficult to solve, a circuit driving scheme needs to be replaced, the ultra-high brightness light emitting diode is used, a driving circuit and the light gathering cup are designed again, and finally the brightness meets the exposure requirement. Compared with a flash lamp, the ultra-high brightness light-emitting diode has slightly reduced brightness, but is safe, reliable, easy and convenient to use, and the flash lamp needs more professional technology to be matched with a shutter to shoot a photo meeting the requirement. The partial circuit adopts independent power supply and is separated from the camera circuit, so that the power consumption of the camera is reduced, and the condition that the power consumption of the whole camera is large and the intrinsic safety requirement cannot be met is avoided.

For a battery of a single lens reflex camera, it is necessary to change all of the cell and the protection circuit. Firstly, the lithium ion activity ratio of the battery cell is high, so that the possibility of violent heating, liquid leakage and combustion can be caused when the battery cell is in short circuit, and obviously, combustible gas can be ignited, so that the battery cell must be an explosion-proof battery cell, and fundamental solution is carried out on structural materials; secondly, the protection of the battery core usually includes charging overvoltage and overcurrent protection and discharging overcurrent protection, but the protection is generally large, and when a load is short-circuited and has very large energy instantly, combustible gas can be ignited, so that the dual protection function of the battery management system is realized by reducing a protection threshold and carrying out dual protection, and then matching with an electric quantity monitoring technology, so as to achieve the intrinsic safety class of explosion protection.
