(1) the difference between the control temperature of the system and the actual temperature of the user is too large
Office building control system is a common problem in terms of design and product performance, which is the accuracy of temperature control. In particular, there is no accurate sampling room temperature and humidity device and matching system analysis software, making the building system setting temperature and customer indoor temperature and humidity is difficult to match. The temperature in the usual area of the customer is difficult to be stable between 22 and 25 centigrade. The temperature can only be adjusted through the fan coil in the room, but it is difficult to adjust it through the new wind.
(2) failure of the system monitoring function part
Due to the design, installation and transformation of the parts of the building, some of the detection and alarm functions have been failed. The monitoring function of the system itself has some problems, especially the host alarm function is unstable, there is a false positive phenomenon. It appears every two or three months on average. The main reason is that there are some defects in the design of main control software, so we need to regularly organize and adjust the main control system, otherwise there will be errors in program operation, resulting in the host's false positives. This work has a strong technical requirement, and in most cases it can only be repaired by the manufacturer.
(3) short system setting cycle and lack of record analysis table
The system has a single operation cycle, and if it meets the Spring Festival or the long holiday, it is necessary to work overtime to adjust the operating time of the equipment. Most building control systems lack data analysis charts, that is, there is no chart output for collecting system data and analyzing data. This is not conducive to the analysis of energy conservation and emission reduction by the engineering management departments and the formulation of effective energy saving plans.
(4) the outdoor floodlighting system of the building self-control is higher than the single intelligent outdoor lighting system
The intelligent outdoor floodlighting system produced by some manufacturers can automatically turn on or off floodlighting according to the brightness of outdoor light, and its price is lower relative to the building system. The method of building control system used in the area of Beijing is a reference to the Tiananmen: the time to set the light opening time, but also need manual operation in rainy weather.
