As defined herein, computer readable media does not include non-transitory media such as modulated data signals and carrier waves.
[0038] like Figure 1 As shown, the present invention provides a method for intelligent control of light and heat environment of a library, the method comprising:
[0039] Step 1: Model the library space and divide it into subspaces:
[0040] 1.1. Establish a spatial geometric electronic model of the library, including detailed information on the building structure, window locations, and lighting equipment layout;
[0041] 1.2. Use the spatial density clustering method to automatically divide the spatial geometry into multiple subspaces, where the light and thermal environments of each area within each subspace are similar.
[0042] For example, the 5F reading area of a certain library covers an area of 1,000 square meters, with a large space, multiple windows and lighting systems.
[0043] The spatial density clustering method can be used to divide the reading area into 10 representative subspaces, each of which is approximately 100 square meters, to ensure that the light and heat environments of various areas within each subspace are similar.
[0044] Specifically, the environments of various reading table areas near the windows can be made similar, and the reading table areas with similar environments can be divided into the same subspace. The light and heat environments of the reading tables within this subspace, for example, if there are 5 reading tables, are similar. Therefore, one light environment sensor and temperature sensor can be used to correspond to this subspace. There is no need for 5 sensors, thus saving sensors.
[0045] Step 2: Based on the constructed spatial geometric electronic model and the divided subspace, perform experimental measurements of the light environment sensor and the temperature sensor to obtain the measurement data of the readings corresponding to the light environment sensor and the temperature sensor:
[0046] 2.1. Arrange a group of light environment sensors and temperature sensors in each representative subspace;
[0047] For example, a set of light environment sensors and temperature sensors are installed in each subspace, totaling 20 sets of sensors;
[0048] 2.2. Under different set values of the air outlet temperature and the air volume of the air conditioner in each subspace, respectively record the first readings corresponding to the light environment sensor and the temperature sensor;
[0049] For example, the air outlet temperature of the air conditioner can be adjusted to 20°C to 30°C, and when the air volume is medium, the first readings corresponding to the light environment sensor and the temperature sensor are recorded respectively;
[0050] 2.3. Under different setting values of the opening of the curtain in each subspace, the second readings corresponding to the light environment sensor and the temperature sensor are recorded respectively;
[0051] Here, the curtains can be adjusted to fully open, half open and fully closed states respectively, and the reading changes of the light environment sensor and the temperature sensor after each adjustment are recorded.
[0052] 2.4. Under different setting values of the illumination intensity of the lighting system at different parts of each subspace, respectively record the third readings corresponding to the light environment sensor and the temperature sensor;
[0053] Here, the lighting system can be adjusted to record the readings of the light environment sensor and the temperature sensor under high, medium and low light intensities.
[0054] 2.5. Conduct several groups of experiments under different external environments to obtain readings corresponding to the light environment sensors and temperature sensors of the several groups of experiments, and perform nonlinear regression on the readings corresponding to the light environment sensors and temperature sensors of each group of experiments to fit and obtain fourth readings corresponding to the light environment sensors and temperature sensors under any external environment; wherein different external environments include: seasons, time, outdoor temperature, weather conditions, etc.
[0055] Here, dozens of measurements can be performed under various random combinations of spring, summer, morning, noon and evening, sunny days, rainy days, and outdoor temperatures ranging from 25°C to 35°C, and the readings corresponding to the light environment sensors and temperature sensors obtained from the dozens of measurements can be subjected to nonlinear regression to fit the changes in the readings corresponding to the light environment sensors and temperature sensors under any external environment.
[0056] Step 3: Based on the measured data, perform a light-heat cross-effect simulation to obtain a light-heat cross-effect simulation result:
[0057] 3.1. Using the first, second, third and fourth readings as calibration benchmarks, run all possible combinations of light-heat cross-effects of air conditioning, curtains and lighting systems in the space geometry electronic model;
[0058] For example, based on the measured data in step 2, all possible combinations of air conditioning, curtains, and lighting systems can be simulated in the electronic model, totaling 11 (air conditioning outlet temperature) × 3 (air conditioning air volume status) × 3 (curtain status) × 3 (lighting status) = 297 combinations.
[0059] 3.2. Run all possible combinations of light-heat cross-effects of air conditioners, curtains, and lighting systems in the spatial geometric electronic model, and simulate the readings of light environment sensors and temperature sensors corresponding to each light-heat cross-effect combination of each subspace in each arbitrary external environment, as the light-heat cross-effect simulation result, to provide a basis for subsequent control.
[0060] Here, computer simulation can be used to obtain the readings corresponding to the environmental sensors and temperature sensors in each subspace under each combination as the simulation results of the photothermal cross-impact, and a photothermal environment database can be established to store the photothermal cross-impact simulation results.
[0061] Step 4: Based on the simulation results of the light-heat cross-effect and the real-time collected lighting requirements and comfortable temperature requirements of each subspace of the library, implement the light-heat environment control of the library:
[0062] 4.1. Real-time collection of readers’ lighting requirements and comfortable temperature requirements for each subspace under the current external environment of the library;
[0063] Here, the lighting and temperature requirements of the current external environment of the library reading area are monitored in real time. For example, at 2 pm in summer, it is sunny outside, the light is strong, and the outside temperature is 35°C. Readers hope to reduce the light intensity and keep the temperature at around 24°C.
[0064] 4.2. Based on the lighting requirements and comfortable temperature requirements of each subspace, query the setting values of the corresponding air conditioning, curtains, and lighting systems from the light-heat cross-effect simulation results;
[0065] Here, the lighting and temperature requirements of the current external environment of the library reading area can be input into the light-heat cross-impact simulation results, and the optimal air-conditioning temperature can be inferred to be set to 24°C, medium air volume, half-open curtains, and a lighting system adjusted to medium light intensity.
[0066] 4.3. Based on the queried set values, the corresponding control signals are sent out through the building intelligent control system to implement adjustment and control of the air conditioning, curtains, and lighting systems to optimize the light and heat environment of the library.
[0067] Here, the building intelligent control system can automatically adjust the air conditioning, curtains and lighting system according to the above-mentioned inversely derived set values of the outlet temperature, the air volume, the curtain opening and the light intensity of the lighting system, so as to optimize the light and heat environment of the reading area.
[0068] According to another aspect of the present invention, a computer-readable storage medium is provided, on which computer-executable instructions are stored, wherein when the computer-executable instructions are executed by a processor, the processor is caused to execute the method described in any of the above embodiments.
