Debugging of stage lighting


① Carefully check whether the external connection of each stage lamp is correct and whether the appearance is new. ② Carefully check the operating status of the single machine and the overall operating status. ③ Strictly comply with the technical requirements of the stage lamps and lanterns stated in the contract.

After the above projects are completed, it is necessary to check whether the running speed of the network computer dimming station and the computer lamp console is consistent with the action response time of the on-site lamps, computer lamps, color changers, hoods and other online controlled equipment. Check whether the lamp, color changer, and hood self-check are normal. In addition: pay attention to whether the lighting system, audio system, and video system interfere with each other. If so, record the time of interference and the model of the specific equipment, and then Useful for future resolution. 12.7 Overall debugging When the debugging of each project has been completed, and it is confirmed that each equipment is in good condition, and there is no obvious debugging error, the overall debugging of the entire system should start. The difference from the individual testing of each equipment and system is that the comprehensive overall There is no clear specific adjustment position for debugging. Its main task is to check whether their interrelated working parts are coordinated during the coordinated operation of each system, check whether they will affect and interfere with each other when they work together, and check the adjustment of the lighting system. Whether the light movement will interfere with the sound system and so on. 12.8 System simulated test run After all the equipment has been debugged, the process that must be carried out before the official operation is the simulated run of the system. Since the lighting system of the Happy Valley Indoor Theater in Beijing Overseas Chinese Town is relatively complicated, the working status is also different. During project debugging, it is difficult to find hidden dangers or deficiencies, but once the project is completed, the actual system running time will be much longer, and there are often phenomena of overtime and overload operation, which have already existed in the system at that time and have not been used. The hidden dangers and deficiencies found may expand rapidly, bringing adverse effects to both you and the project. The simulation operation is to understand the working status of the system in an environment similar to the actual operation, find problems, and prevent problems before they happen. .

First of all, use an ammeter to check the current of each phase of the power supply line when the equipment of each project is running individually and overall. Although there are corresponding requirements for power supply lines during design and construction, and a general understanding of the current distribution of each phase, the actual operating conditions will definitely differ from the theoretical values. Measure current conditions during actual operation. Use an ammeter to measure the time of each phase and the number of operating equipment. If it is found that there is a large gap between the actual measured value and the theoretical value, or there is a large gap between the current distribution ratio of each phase, or there is an abnormal phenomenon in the line current, it must be rectified again. To ensure electricity safety.

Secondly, it is necessary to check the working stability of each equipment in full load operation and long-term operation. Finally, check the heat generation of each device during full-load operation and long-term operation. The equipment of the lighting system is basically power-consuming equipment, and there will be different degrees of heat during operation, especially the load carried by the silicon cabinet, computer lamps and other high-power equipment, the heat is usually more obvious, so to a certain extent The heating phenomenon on the computer will not have any impact on the use of the equipment and the safety of the system and equipment.

However, if there is no proper heat dissipation space reserved during installation, or the heat dissipation of the equipment itself is under long-term and heavy-duty operation, then it should be resolved, otherwise the equipment will be protected if it is light, and the equipment will be damaged if it is serious. Generally, if the equipment is seriously overheated within the normal working range, the equipment must be replaced; if there is no suitable heat dissipation space and the equipment generates a lot of heat, forced ventilation should be considered, and the owner should be clearly informed to carry out regular dust cleaning and equipment maintenance. Since this simulation operation is a very important and necessary work, every work at this time will be exchanged for the long-term stability of the equipment and the safety of the system work.

In particular, the heating conditions of power supply lines and equipment will be directly related to the safety of the project, so all engineering and technical personnel must pay great attention. Because there are many items to be debugged, set and inspected in lighting engineering, and these results and problems are important reference materials for future use and maintenance, it is necessary to record the results and problems during each step of work, and then carry out necessary analysis and summary. The recorded data that is useful to users should be handed over to them; for the recorded data that is useful for future maintenance, the stage lighting equipment should be properly kept by the designer.

The recorded results include: the location number of the device, the setting status of the device, the test data during debugging, the information of related program editing, etc.; the recorded problems include: the problem of the working environment of the device, the problem of device interference, the problem of the operating status Questions and more. The completion acceptance of the project is a grand parade of the entire system and a comprehensive experience of the overall project quality, which is of great significance. Therefore, the acceptance process and acceptance requirements are relatively important. Some of the contents are briefly introduced as follows: Initial inspection: Yes A general inspection of the stage system engineering mainly starts from the intuitive equipment to check the installation of various equipment in place, check the various lists of equipment, and ensure that there are no omissions, no errors, no replacements in the number of installed equipment, and rule out installation failures. In place, the installation is not standardized, and the appearance of some equipment is damaged and the maintenance of the equipment during the installation process. Find problems and solve them in time.

The initial inspection requires the strong cooperation of Party B and the cooperation of the supplier. System part test: This is an important part of the whole system after the initial inspection is completed. After ensuring that all equipment is in place and there is no omission, the whole system can be tested. The test is carried out according to each subsystem. , the specific test method and specific test content are specified in the lighting, audio and subtitle monitoring systems in the back. System overall test: After testing some subsystems of the system, if the test condition of each subsystem is good, it does not mean that the whole system will be good, and an overall test of the system is required, that is, when all subsystems are tested In the case of simultaneous operation, look for factors such as mutual interference to ensure the perfection of the overall system performance.

Note: In the process of system testing and acceptance, special attention should be paid to the inspection of hidden links, so as to expose the hidden parts, and never miss any fine details, so that the system is truly foolproof.
