Description

Technical Field

[0001] The present invention relates to the field of elevator lighting control, and more particularly to an elevator lighting control system. Background Art

[0002] Elevators serve several specific floors in a building. The car is the box-shaped space inside the elevator used to carry and transport people and materials. The car is generally composed of main components such as the car bottom, car walls, car top, and car doors.

[0003] In modern cities, many new buildings are rising in height, and the emergence of super-high buildings has led to the emergence of elevators. However, super-high buildings generally involve multiple floor attributes. For example, a single super-high building may involve food, entertainment, business offices, and residences according to its commercial planning. Since there are many people entering and exiting the elevator every day in super-high buildings, the performance and service of the elevator itself are also subject to higher requirements. In addition to ensuring safety, it is also necessary to provide better services and a better experience.

[0004] Elevators are the most important vertical transportation tools in modern buildings. As people's living standards continue to improve, the public pays more and more attention to the comfort and safety of elevators. As the part of the elevator that passengers directly contact, the appearance comfort and safety of the elevator car are particularly important. As the main light source in the elevator car, the appearance and lighting combination of the elevator car ceiling directly affect the overall visual effect of the elevator car.

[0005] The LED light strips of conventional elevators are ordinary light strips, which light up when powered on and go out when powered off. If TTL light strips are used, the chip of the light strip can only be controlled through the SPI protocol to achieve light changes. The control method of conventional starry sky ceilings is either infrared or Bluetooth control, which has a single control method and cannot automatically adjust the internal lighting of the elevator car according to the riding environment inside the elevator car, which has certain limitations.

[0006] In order to solve the above problems, a technical solution is now provided. Summary of the invention

[0007] In order to overcome the above defects of the prior art, an embodiment of the present invention provides an elevator lighting control system to solve the problems raised in the above background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An elevator lighting control system, comprising a lighting switch power supply module, a liquid crystal display control module, a DMX512 lighting control module, a DMX512 light source module and a lighting output module;

[0010] The lighting switch power supply module is used to control the lighting power supply;

[0011] The LCD display control module is used to control the DMX512 lighting control module;

[0012] The DMX512 lighting control module is used to control the DMX512 light source module;

[0013] The DMX512 light source module is used to control the light output module;

[0014] The light output module is used to output light.

[0015] In a preferred embodiment, the operation of the DMX512 lighting control module specifically includes the following:

[0016] Collect the brightness parameters per unit time inside the elevator car;

[0017] The brightness average value and brightness standard deviation value are calculated, and the brightness intensity threshold and brightness discrete threshold are set. The brightness average value is compared with the brightness intensity threshold, and the brightness standard deviation value is compared with the brightness discrete threshold. If the brightness average value is not greater than the brightness intensity threshold, or the brightness standard deviation value is not less than the brightness discrete threshold, then there is no need to adjust the brightness. Once the brightness average value is greater than or equal to the brightness intensity threshold, and the brightness standard deviation value is less than the brightness discrete threshold, then the brightness needs to be adjusted.

[0018] By adopting the above technical solution, when the internal environment of the elevator car is dark, the internal environment of the elevator car can be automatically brightened, and when the internal environment of the elevator car is bright, the internal environment of the elevator car can be automatically dimmed, which can improve the comfort of passengers.

[0019] In a preferred embodiment, the operation of the DMX512 lighting control module specifically includes the following:

[0020] Collect the temperature parameters per unit time inside the elevator car;

[0021] The temperature average value and temperature standard deviation value are calculated, the temperature intensity threshold and the temperature discrete threshold are set, the temperature average value is compared with the temperature intensity threshold, and the temperature standard deviation value is compared with the temperature discrete threshold. If the temperature average value is not greater than the temperature intensity threshold, or the temperature standard deviation value is not less than the temperature discrete threshold, then there is no need to adjust the brightness. Once the temperature average value is greater than or equal to the temperature intensity threshold, and the temperature standard deviation value is less than the temperature discrete threshold, then the brightness needs to be adjusted.

[0022] By adopting the above technical solution, when the internal ambient temperature of the elevator car is high, the internal environment of the elevator car can be automatically dimmed to reduce the heat generation. When the internal ambient temperature of the elevator car is low, the internal environment of the elevator car can be automatically brightened to increase the heat generation, thereby improving the comfort of passengers.

[0023] In a preferred embodiment, the operation of the DMX512 lighting control module specifically includes the following:

[0024] Collect the vibration parameters inside the elevator car per unit time;

[0025] Install vibration sensors inside the elevator car to continuously collect vibration signals;

[0026] The vibration intensity inside the elevator car is calculated using the root mean square formula as follows: In the formula, x i Represents each sampling point of the vibration signal, N represents the total number of sampling points, and M represents the vibration intensity;

[0027] Set the vibration intensity threshold, marked as S;

[0028] If M≤S, the lights inside the elevator car are operating normally;

[0029] If M>S, turn off the lights inside the elevator car.

[0030] By adopting the above technical solution, under normal vibration amplitude, the lights inside the elevator car remain on. When the vibration amplitude inside the elevator car is large, the lights are likely to shake. At this time, the lights inside the elevator car are turned off, but the normal lights inside the elevator car are still turned on normally, which can improve the comfort of passengers.

[0031] In a preferred embodiment, the operation of the DMX512 light source module includes the following specific contents:

[0032] Receive the signal from the DMX512 lighting control module:

[0033] Classify the signals sent by the DMX512 lighting control module;

[0034] Analyze the signals sent by the classified DMX512 lighting control modules;

[0035] The analyzed signal from the DMX512 lighting control module is recorded.

[0036] In a preferred embodiment, the operation of the light output module specifically includes the following:

[0037] Receive the signal from the DMX512 light source module;

[0038] Select the light intensity and light type according to the signal.

[0039] In a preferred embodiment, the logic for obtaining the brightness parameter is:

[0040] Multiple brightness sensors are installed inside the elevator car to aggregate the brightness signal data. After the aggregation is completed, the brightness average value is calculated, and the obtained brightness average value is the brightness parameter.

[0041] In a preferred embodiment, the temperature parameter acquisition logic is:

[0042] Multiple temperature sensors are installed inside the elevator car to aggregate the temperature signal data. After the aggregation is completed, the temperature average value is calculated, and the obtained temperature average value is the temperature parameter.

[0043] The technical effects and advantages of an elevator lighting control system of the present invention are as follows:

[0044] 1. Through the DMX512 lighting control module and DMX512 light source module, DMX512 lighting control technology is introduced in the elevator field, so as to realize the unified control of different types of lamps;

[0045] 2. Through the DMX512 lighting control module and DMX512 light source module, first collect the brightness parameters per unit time inside the elevator car, calculate the brightness average value and brightness standard deviation value, then compare the brightness average value with the brightness intensity threshold, and compare the brightness standard deviation value with the brightness discrete threshold value, and automatically adjust the brightness of the lights inside the elevator car according to the comparison results, that is, when the internal environment of the elevator car is dark, the internal environment of the elevator car can be automatically brightened, and when the internal environment of the elevator car is bright, the internal environment of the elevator car can be automatically dimmed;

[0046] 3. Through the DMX512 lighting control module and DMX512 light source module, the temperature parameters per unit time inside the elevator car are collected, the temperature average value and temperature standard deviation are calculated, and then the temperature average value is compared with the temperature intensity threshold, and the temperature standard deviation is compared with the temperature discrete threshold. According to the comparison results, the light temperature inside the elevator car is automatically adjusted, that is, when the ambient temperature inside the elevator car is high, the internal environment of the elevator car can be automatically dimmed to reduce the heat. When the ambient temperature inside the elevator car is low, the internal environment of the elevator car can be automatically brightened to increase the heat, thereby improving the comfort of passengers;

Through the set DMX512 lighting control module and DMX512 light source module, the vibration parameters per unit time inside the elevator car are collected, the root mean square is used to calculate the vibration intensity inside the elevator car, and the vibration intensity threshold is set. When the vibration intensity inside the elevator car is less than or equal to the vibration intensity threshold, the lights inside the elevator car operate normally. When the vibration intensity inside the elevator car is greater than the vibration intensity threshold, the lights inside the elevator car are turned off, that is, under normal vibration amplitude, the lights inside the elevator car remain on. When the vibration amplitude inside the elevator car is large, the lights are likely to shake. At this time, the lights inside the elevator car are turned off, but the normal light inside the elevator car is still turned on normally, which can improve the comfort of passengers.

[0048] Figure 1 The present invention is a structural schematic diagram of an elevator lighting control system. DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Example 1

[0055] The DMX512 light source module is used to control the light output module;

[0056] The light output module is used to output light.

[0057] It should be noted that the lighting switch power supply module can control the lighting power supply, that is, it can control the power supply of the DMX512 lighting control module;

[0058] The LCD display control module is equipped with an LCD touch screen, which is used by the staff to control the DMX512 lighting control module through the LCD display control module;

[0059] The lighting output module can automatically output the corresponding lighting type based on the results.

[0060] The operation of the DMX512 lighting control module specifically includes the following:

[0061] Collect the brightness parameters per unit time inside the elevator car;

[0062] The brightness average value and brightness standard deviation value are calculated, and the brightness intensity threshold and brightness discrete threshold are set. The brightness average value is compared with the brightness intensity threshold, and the brightness standard deviation value is compared with the brightness discrete threshold. If the brightness average value is not greater than the brightness intensity threshold, or the brightness standard deviation value is not less than the brightness discrete threshold, then there is no need to adjust the brightness. Once the brightness average value is greater than or equal to the brightness intensity threshold, and the brightness standard deviation value is less than the brightness discrete threshold, then the brightness needs to be adjusted.

[0063] Through the above structure, the brightness parameters per unit time inside the elevator car are collected, the brightness average value and the brightness standard deviation value are calculated, and then the brightness average value is compared with the brightness intensity threshold, and the brightness standard deviation value is compared with the brightness discrete threshold. The brightness of the lights inside the elevator car is automatically adjusted according to the comparison result. When the internal environment of the elevator car is dark, the internal environment of the elevator car can be automatically brightened. When the internal environment of the elevator car is bright, the internal environment of the elevator car can be automatically dimmed, which can improve the riding comfort of passengers.

[0064] The operation of DMX512 lighting control module also includes the following:

[0065] Collect the temperature parameters per unit time inside the elevator car;

[0066] The temperature average value and temperature standard deviation value are calculated, the temperature intensity threshold and the temperature discrete threshold are set, the temperature average value is compared with the temperature intensity threshold, and the temperature standard deviation value is compared with the temperature discrete threshold. If the temperature average value is not greater than the temperature intensity threshold, or the temperature standard deviation value is not less than the temperature discrete threshold, then there is no need to adjust the brightness. Once the temperature average value is greater than or equal to the temperature intensity threshold, and the temperature standard deviation value is less than the temperature discrete threshold, then the brightness needs to be adjusted.

[0067] Through the above structure, the temperature parameters per unit time inside the elevator car are collected, the temperature average value and the temperature standard deviation value are calculated, and then the temperature average value is compared with the temperature intensity threshold, and the temperature standard deviation value is compared with the temperature discrete threshold. The light temperature inside the elevator car is automatically adjusted according to the comparison result. That is, when the ambient temperature inside the elevator car is high, the internal environment of the elevator car can be automatically dimmed to reduce the heat generation. When the ambient temperature inside the elevator car is low, the internal environment of the elevator car can be automatically brightened to increase the heat generation, thereby improving the comfort of the passengers.

[0068] The operation of DMX512 lighting control module also includes the following:

[0072] Set the vibration intensity threshold, marked as S;

[0073] If M≤S, the lights inside the elevator car are operating normally;

[0074] If M>S, turn off the lights inside the elevator car.

[0075] Through the above structure, the vibration parameters per unit time inside the elevator car are collected, the root mean square is used to calculate the vibration intensity inside the elevator car, and a vibration intensity threshold is set. When the vibration intensity inside the elevator car is less than or equal to the vibration intensity threshold, the lights inside the elevator car operate normally. When the vibration intensity inside the elevator car is greater than the vibration intensity threshold, the lights inside the elevator car are turned off, that is, under normal vibration amplitude, the lights inside the elevator car remain on. When the vibration amplitude inside the elevator car is large, the lights are likely to shake. At this time, the lights inside the elevator car are turned off, but the normal lights inside the elevator car are still turned on normally. That is, the lighting control of the present invention mainly controls the starlight top lights on the top of the elevator car, and the normal lights inside the elevator car do not need to be controlled, thereby improving the comfort of passengers.
