There are different kinds of regional interpretation systems in the market. Because the zonal interpretation system needs to be wired and installed in the exhibition hall in advance, if it is found that the effect is not good, the later replacement will not only cost extra money, but also be carried out during the normal opening of the museum, which will be troublesome and affect the normal reception work. Therefore, it is very important to choose a reliable hierarchical navigation hierarchical interpretation system. As an important explanation and reception equipment of the exhibition hall, what should be paid attention to when choosing? Mainly from the following points:
situation
Have you done many cases, especially the large exhibition hall of 10,000 square meters or the benchmarking exhibition hall? Because of the large projects, this kind of exhibition hall is also strict in the inspection of suppliers, and the technical ability, construction ability and after-sales ability are all the objects of inspection. If most projects are only one or two thousand square meters or even hundreds of square meters, it means that they have not passed the assessment of large project manufacturers and can only do some small projects with low quality and technical requirements. Pay attention to the routines of some unscrupulous manufacturers when investigating cases. Take some cases of explaining headphones as cases of explaining systems in different regions, or take other people's pictures as your own cases. At least you must be able to provide videos after construction to be more credible. You can also make a field trip if you have the conditions. If the situation is rare, be cautious. Unless you are willing to be a mouse to help the manufacturer test the equipment, the partition interpretation system is not as good as the interpreter. Once installed, it is necessary to re-route and open holes, some of which are difficult to repair and more troublesome.
system reliability
The partition explanation system needs to receive important VIPs frequently, and many exhibition halls need to receive multiple groups of VIPs every day, so the stability and reliability of the system are very important. Avoid using the products of manufacturers whose systems have not been turned off for more than two years, because partition interpretation systems often run for months or even years without turning off the power supply. If the manufacturer does not run the project for a long time, it is difficult to ensure the long-term stability and reliability, otherwise it is equivalent to planting a time bomb, and I don't know when I will receive an important visiting team and dare not use it. In addition, if you encounter an RFID or Bluetooth beacon with a battery in the device, be sure to keep your eyes open. This kind of equipment uses batteries and needs to be replaced regularly (one or two years). Moreover, due to the different consistency of battery discharge, the induction function in the later service life is also easily affected, which often leads to problems in switching between different regions. Watch your step on the pit.
R&D strength of manufacturers
Be sure to find the original factory of system research and development, and avoid looking for agents. Unlike consumer electronics, such products are the same for anyone who sells them. The general agent of this professional product is incapable of after-sales service. Many agents are small companies with several people. Once they go bankrupt, they may face the dilemma of no after-sales service. The original factory of the system not only supports the system to be more timely, but also has a safer after-sales service. Well-known domestic teachers explained that there are no more than three original R&D factories, and many big brands are flying all over the Internet. In fact, many old factories are not in the eyes of the industry. The common routine is that you look at many companies, but they are all vests of a dirty company.
Baidu search "How to choose a reliable division to explain manufacturers" found a series of industry popular science articles published on the deep Internet, which can refer to the content and avoid the so-called big brand companies that only exist on the Internet.
Look at the technology used by the manufacturer.
At present, the mainstream partition interpretation technology is divided into four generations. The first generation of partition interpretation technology is based on infrared technology, similar to infrared TV remote control. It belongs to the technology that will be eliminated soon, and it is easily disturbed by many factors such as dust, light source, reflection, occlusion and so on. The method of use has some disadvantages. The lecturer needs to put the photosensitive end of the controller on it, but can't cover it, for example, put it in his pocket and cover it with his arm, which makes the experience very poor.
The second generation of regional interpretation technology-RFID, which is similar to the card-swiping sensing equipment used in daily life, is not effective in complex buildings because it cannot accurately judge the region. For example, the channel is S-shaped and U-shaped, which is easily disturbed and confused.
Bluetooth, the third generation of regional interpretation technology, makes rough position judgment according to signal strength, with an accuracy of 3 -5 meters. The signal is easily blocked by the human body and the signal is unstable. The effect is poor in overhead floors, jumps or high-rise buildings.
The fourth generation partition interpretation technology-decimeter-level high-precision positioning technology based on deep interconnection, because the positioning accuracy can be accurate to decimeter, can effectively avoid the problems existing in the first, second and third generations from the principle core layer, and has a good use experience, which can make partition switching smooth and will not jump back and forth at the junction of two areas.
Some manufacturers use the technology of combining the first generation infrared and the second generation RFID. Although it has been improved in some aspects, it has inherited some shortcomings of both, and its reliability may be worse. In theory, a winged ship can fly, but the result is that the load in the sea is not as good as that of a ship, and the flight speed and fuel consumption are not as good as that of an airplane. There are also some unscrupulous manufacturers whose products are backward in technology. They call the old products the seventh and eighth generation, and some manufacturers fly from the second generation to the sixth generation with serial port control function. Just smile. The latest mobile phone on the market is 5G. If you meet a manufacturer who sells 6G and 7G mobile phones, congratulations, either you meet a nonsense or you meet a cottage manufacturer.

You can refer to the content inside, and don't copy the title by mistake in the cottage factory. If you browse in official website and find articles and pictures similar to ours, it means that unfortunately we have been copied again, because the technology is difficult to copy, and it is even more difficult to copy articles and pictures.
Other factors
There are also dimensions including product appearance and RF frequency band. Check whether the manufacturer's products are suitable. The previous article has already talked about it, so I won't expand it here. Baidu search "partition explanation system purchase precautions" to find articles published by Deep Interconnection, and suggest to find articles published by Deep Interconnection. Shanzhai is so powerful that our products have not been shanzhai for five years, so an article with the same name may come out in a few days after publication.
