Problems with building intercom systems
1. The quality of products varies from one brand to another, and the imitation of copycats is growing. The more developed the intercom industry, the more people are joining the security industry. Many manufacturers start assembling security security products under simple manpower and equipment. The low cost of products is not high, but they are not formal industrial structures. The intelligent building intercom system is a highly specialized product that requires high input costs and a long recycling period. It has high requirements for technology, experience and maintenance.
However, a large number of low-cost technology companies influx, the industry hides a huge risk: First, market risk, the market will inevitably stand up for the advantages and disadvantages, a large number of lost professional level production enterprises are facing elimination, resulting in product after-sales service can not keep up; Still a user. The second is social risks. Intercom product companies with low-cost and quality standards can not only provide qualified building intercom products for cities and residents, but may instead be a large number of safety hazard systems.
It is also through the same testing agency to test qualified products of different manufacturers. In the actual use process, there is still a great difference in performance. The qualified inspection only represents that the product can be used in the market, and it does not mean that the product will not have quality problems. In addition, there will also be differences between the products submitted for inspection and the actual mass produced products; at the same time, there will be differences in the use of components for different batches of products, resulting in the quality of finished products.
2. Inadequate system design and installation, resulting in poor system performance The main reasons for analyzing poor engineering in the smart building intercom system are; improper construction design, first, the intelligent building intercom system door machine is designed to be installed in open air, but not Do waterproof, moisture-proof treatment, causing equipment to cause water failure; Second, the door machine is designed on the door, because the door switch, it will bring vibration to the door machine to cause poor contact failure; The third is to install network-connected equipment in the outdoor Caused by the existence of such measures as water repellent treatment and lightning protection and further cause failure; Fourth, poor line construction does not cause one failure, the entire building vacant system shut down; five is to cut down the installation of power and load power shortage, resulting in unstable power supply , Image warping jitter failure; Sixth, do not use the original power supply to create unstable operating conditions; Seventh, improper design of the door lock, resulting in door panel deformation or bad quality of the electric lock caused by the door element failure occurs.
All kinds of failures mentioned above, users and property management companies are unable to grasp this link, and can only attribute their responsibilities to the problems of smart building intercom products and poor construction quality. In addition, the construction process is rough: For example, there is no proper stainless steel screw, no wiring, no welding, and no insulated heat shrinkable tubing. In particular, after the copper wires are twisted together, only the electric tape is wound in disorder. This situation is not much, this is caused by loose wiring, disconnection or poor contact, spark interference and wiring oxidation.
In addition, it is caused by natural factors; equipment is not cleaned and maintained, there is no routine inspection, corrosion caused by dust, insects, rodents, rat urine, etc., and non-human failure. For example, some tiger insects climb into floor platforms, power supplies, extensions, and mainframes during the winter. This type of equipment will generate tiny heat during work, allowing insects to warm over the winter, causing circuit board short circuits and equipment failure.
3. System usage errors and high frequency of use In general, intelligent building intercom systems do not stop running for 24 hours, especially for residential buildings. The frequency of use of intercom systems is particularly high, and it is also relatively prone to failure; on the other hand, In the system after the installation of the wrong operation, due to erroneous operation, or the use of personnel to arbitrarily modify the system configuration, resulting in illegal operations or non-maintenance personnel log on the system to operate, may cause the system to appear these problems.
4. The advantages and disadvantages of the construction of transmission lines The intelligent building intercom products, including mainframes, extensions, floor switches, and networked switches, are the key to the stability of the core technology and quality system of products. The transmission part of the system's wire and wiring is the absolute key to the merits of the system. At present, most building intercom products use the traditional video line plus signal line method. Not only is the cost of the wire higher and the construction is more troublesome, it is easily disturbed by environmental factors in the transmission process and affects the stability of the system. The network is the networking core of the entire digital building intercom system. The stability of network digital networking performance is the greatest demand for the stability of building intercom systems. Especially in the building networking of large buildings, the networking core technology has an important influence on the stability of the entire intelligent building intercom system.
5. Failure to comply with the project acceptance smart building intercom, even after acceptance, is generally stable after the new system has just been installed and commissioned. As it has not yet passed the test of harsh environments, it is difficult to find problems hidden in the construction, especially It is a wiring project. In the outdoor environment, after the system has been frequently used every day through wind and rain showers, solar baptism, and intelligent building intercom systems, problems will gradually emerge.
Building intercom system breakdown
With the rapid development of urban building automation, the safe, comfortable and intelligent living environment has gradually become the basic requirement of modern intelligent buildings, and the intercom system has become an important part of demand.
