What should Delco manufacturer do if there is no picture on the explosion-proof camera?
time:2024-04-08 author:DERKE Mechanical

When using explosion-proof cameras, there may be no picture, and what is the reason for this? In order to not delay the normal progress of work, relevant personnel need to have a simple understanding. Changzhou Delco has the following summary.


1. Insufficient power supply for explosion-proof cameras


The power of the switching power supply itself is insufficient, which leads to overheating of the switching power supply, resulting in thermal protection. The inspection method is to check whether there is temperature in the on-site mode power supply. If it is cold, it is a power outage. The solution is to replace the power supply.


2. The power supply voltage of the explosion-proof camera is insufficient


If the explosion-proof camera experiences flickering images, it can be due to insufficient power supply voltage. The explosion-proof camera indicates that the power supply is 12V/2A, and using 12V/1A is likely to cause flickering. This is because the power supply is insufficient and needs to be replaced.


3. Explosion proof camera malfunction,


If only this explosion-proof camera has this fault, it may occur due to the internal program crash of the camera, which is restored after power outage and restart, mainly caused by poor reset circuit.


4. Reverse connection of power lines in engineering construction


The wire is too thin, resulting in a large voltage drop and the camera cannot be started. The solution is to standardize the construction and use a multimeter to measure the input voltage and current of the explosion-proof camera.


5. The transmission line has power supply


If there is overlap with AC power on the video transmission line, it will cause the explosion-proof monitoring camera and the electrolytic capacitor inside the distributor to charge, thereby blocking the video signal output. I have tested this problem in the laboratory and found it on several sites. Test method: Use a multimeter to measure the voltage of the video cable. Solution: Find the connection point of the power supply, which has a full isolation function inside to prevent this phenomenon from occurring. Moreover, the equipment can work normally with a maximum voltage of 220 volts on the video circuit, and it will not be transmitted to the explosion-proof monitoring camera or the main control room.
