What kind of illuminance transmitter should the exhibition hall choose
With the continuous construction of my country's economy and culture, people's requirements for art have become higher and higher. Visiting museums, cultural centers, archives and other exhibition halls has become an important part of people's cultural life. In these pavilions, light plays a key role in how to present and protect the exhibits. Appropriate lighting can not only bring a good exhibition experience to the audience, but also protect the exhibits and effectively reduce the damage to the exhibits caused by light radiation. Therefore, in the exhibition hall, we need to monitor the light in real time, but to monitor the light, we need an illuminance transmitter. The illuminance transmitters on the market are basically wall-mounted, which is inconvenient and unsightly. How should we choose? ? Here we recommend ceiling-mounted illuminance transmitters. The ceiling-mounted illuminance transmitter is not only stylish and beautiful in appearance, but also solves the problem of incomplete monitoring of the wall-mounted illuminance transmitter in the exhibition hall. The ceiling-mounted illuminance transmitter is installed on the top of the exhibition hall. With a larger exhibition area, it can also upload data in real time, meeting the needs of museums, cultural centers, and archives for light monitoring. The above describes the usage scenarios of the ceiling-mounted illuminance transmitter, and then I will give you a detailed introduction to the working principle and installation method of the ceiling-mounted illuminance transmitter. The working principle of the illuminance transmitter The illuminance transmitter adopts the hot spot effect principle, mainly using detection components that have a high response to low light. These sensing elements are actually like the photosensitive matrix of the camera Similarly, there is a wire-wound electroplating multi-contact thermopile inside, and the surface is coated with a high-absorption black coating. The hot junction is on the sensing surface, and the cold junction is located in the body, and the hot and cold junctions generate a thermoelectric potential. In the linear range, the output signal is proportional to solar irradiance. The visible light through the filter irradiates the imported photodiode, and the photodiode converts into an electrical signal according to the visible light, and then the electrical signal enters the processor system of the transmitter to output the binary signal that needs to be obtained. Of course, there are many categories of illuminance transmitters, and some categories even optimize the structure described above, especially in order to reduce the influence of temperature. The illuminance sensor also uses temperature compensation circuits. This greatly improves the sensitivity and detection capability of the illuminance transmitter. Selection of light-sensitive ball of illuminance transmitter The light-sensitive transmitter has two measuring ranges, 0~65535 Lux photosensitive ball and 0~200,000 Lux photosensitive ball. The two photosensitive ball devices are the same, but the difference is the measurement range of the illuminance. Because the ceiling-mounted illuminance transmitter is mainly used indoors, and the highest indoor light is only 5000 Lux, so the ceiling-mounted illuminance transmitter photosensitive ball is generally selected from 0 to 65535 Lux. How to install the ceiling-mounted illuminance transmitter The ceiling-mounted illuminance transmitter should be installed on the top of the exhibition hall, and there should be no high obstacles under the illuminance transmitter. After adjusting the horizontal position of the transmitter, fix it firmly. Ceiling type illuminance transmitter installation method: firstly drill holes (aperture 6mm) on the wall to be installed, then put in the expansion tube, and finally fix the mounting screws and the mounting baffle to the place to be installed. The ceiling-mounted illuminance transmitter is a screw fixed hole, just align the hole and install it directly. Wide voltage power input, 10-30V can be used. When wiring the 485 signal, note that the A/B lines cannot be reversed, and the addresses of multiple devices on the bus cannot be conflicted. How to upload data from ceiling-mounted illuminance transmitter The illuminance transmitter is a field networking communication. Multiple illuminance transmitters are connected to the environmental monitoring cloud through the 485 bus and USB to 485 ports. The platform can realize the centralized monitoring of the environmental monitoring equipment connected by wire. Real-time data display, over-limit alarm, historical data query, and data export can be realized on the computer side. In addition to the PC terminal that can query data, the illuminance transmitter can be connected to the environmental host or network concentrator, and the data can be transmitted to the free environmental monitoring platform for mobile phone and computer terminals to view at any time.
