Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Fig. 1 shows a flow chart of an adaptive control method of an LED according to the present invention.
As shown in fig. 1, a first aspect of the present invention provides an internet of things-based LED linkage control method, where the method includes:
s102, enabling the LED group to display light according to control information provided by the first Internet of things device;
s104, receiving control information from second networking equipment, and extracting identity information of the second networking equipment;
s106, inquiring the identity level corresponding to the second networking equipment in a preset control authority level table based on the identity information of the second networking equipment;
s108, comparing the identity level of the second Internet of things device with the identity level of the first Internet of things device;
s110, if the identity level of the second networking equipment is higher than that of the first networking equipment, enabling the LED group to display light according to the control information of the second networking equipment.
It can be understood that if the identity level of the second internet-of-things device is lower than or equal to the identity level of the first internet-of-things device, the LED group is still used for displaying light according to the control program provided by the first internet-of-things device. The control information may be a control program of the LED group, or may be display logic information of the LED group. But is not limited thereto. In general, the LED groups may be customized for display according to control information.
It is understood that the LED group is composed of a plurality of LEDs according to a predetermined arrangement rule. For example, a plurality of LEDs may be arranged on an exterior wall of a hotel or apartment, and at least one LED may be assigned to each room.
It can be understood that the first internet of things device can be a controller of the LED group, a corresponding control program or control model is preset in the controller, and light display is performed on the LED group according to the preset control program or control model.
According to an embodiment of the present invention, receiving control information from a second networked device specifically includes:
presetting the second networking equipment as building indoor alarm equipment, and sensing potential safety hazard data in a corresponding room by each building indoor alarm equipment; when a certain building indoor alarm device senses that potential safety hazard data of a corresponding room is higher than a preset threshold value, recording a current time node;
judging whether the current time node falls into a preset time period or not, and if so, sensing whether a person is in a room or not through intelligent door lock equipment of the corresponding room;
if the LED group is not occupied, triggering the building indoor alarm equipment to generate first alarm information and carrying out alarm in the building, and if the LED group is not occupied, triggering the building indoor alarm equipment to generate second alarm information and taking the second alarm information as control information of the LED group.
It should be noted that the preset time period is a time period during which the LED group can perform light display, and the time period is generally night, for example, 6 to 12 pm. If current time node is daytime, then external natural light or sunlight cover very easily the light that LED group sent, and then can't make LED group carry out effectual light show, consequently whether need judge current time node and fall into the preset time quantum, if yes, then carry out light alarm under the indoor unmanned circumstances of further sensing to outdoor passerby in time discovers the potential safety hazard in this room, and then makes effectual prevention and treatment work, if inform building managers, or report to the police etc.. It will be appreciated that if someone is in the room, the security risk is considered to be in charge, but for safety reasons, an alarm may still be activated in the building. And if the current time node does not fall into the preset time period, directly triggering the building indoor alarm equipment to generate first alarm information and carrying out in-building alarm. Preferably, the first alarm information can be used for combined alarm in a sound and light combined mode. Specifically, the alarm gives out alarm sound and warning light.
It should be noted that the intelligent door lock device includes an outer door handle and an inner door handle, and the sensor of the inner and outer door handles can acquire the holding information of the user, and determine whether the user is going out or entering through the holding information of the inner and outer door handles, so as to estimate whether someone is in the room. Specifically, if the sensor of the outer door handle senses the holding information of the user, and then the sensor of the inner door handle senses the holding information of the user, it can be determined that the user is a door opening entrance motion, and if the current node is located after the entrance motion time node, it can be inferred that someone is in the room. Otherwise, it can be concluded that there is no person in the room.
According to the embodiment of the invention, the light display of the LED group according to the control information of the second networking equipment specifically comprises the following steps:
presetting that the LED group comprises a plurality of LEDs, wherein the building comprises a plurality of rooms, at least one LED is correspondingly arranged on the outer wall of each room, and an association table between the room number and the identification information of at least one LED is established;
extracting a corresponding room number from the control information of the second networked device;
searching in the association table according to the extracted room number, and finding out LED identification information associated with the room number;
and determining a target LED according to the LED identification information, and displaying light by the target LED according to the control information of the second networking equipment.
It should be noted that, for many hotels or apartments, a plurality of building indoor alarm devices are installed indoors, and the building indoor alarm devices may be smoke alarm devices, circuit fault alarm devices, water pipe alarm devices, and the like, so as to facilitate sensing of fault conditions in each room and troubleshooting of potential safety hazards.
It will be appreciated that after a customer enters a hotel or apartment, bad habits are often brought into the hotel or apartment, for example throwing a cigarette butt around, or switching in a high power appliance at an indoor outlet. When a customer goes out, the cigarette ends which are not extinguished easily cause fire hidden troubles. Meanwhile, high-power electrical appliances are easy to cause short circuit or spontaneous combustion of indoor lines, and further cause great potential safety hazards to hotels or apartments. The invention displays alarm information by light through the LEDs arranged on the outer wall, thereby facilitating the hotel management personnel to timely investigate the potential safety hazard of each room from the outside and avoiding personal and property loss.
It should be noted that, when the specific light is displayed, the external LEDs in the room with the potential safety hazard may be turned on, or even the external LEDs in the room may form an alarm sign, so that the manager can accurately lock the position of the room with the potential safety hazard from the indoor space, and perform the hidden danger troubleshooting measures quickly.
According to the embodiment of the invention, each building indoor alarm device respectively senses potential safety hazard data in a corresponding room; when sensing that the potential safety hazard data of the corresponding room is higher than a preset threshold value by certain building indoor alarm equipment, recording a current time node, specifically comprising:
when a customer enters a certain room for the first time, triggering building indoor alarm equipment corresponding to the room to acquire voltage data of indoor lines and carrying out abnormity detection;
presetting the initial length and the expanding step length of a detection time window, and aligning the left edge of the initial detection time window with the moment when the customer enters the room for the first time;
performing maximum overlapping discrete wavelet transform processing on voltage data in a detection time window to obtain a first-level MODWT detail coefficient curve, and acquiring a first-level MODWT detail coefficient value T of each sampling point in the detection time window based on the first-level MODWT detail coefficient curvekIf n sampling points are preset in the detection time window, then

The average value of the absolute values of the difference values of the detail coefficients of other levels of MODWT is taken as a preset threshold value;
comparing absolute values of difference values of first-stage MODWT detail coefficients between two adjacent sampling points in the detection time window with the preset threshold value one by one, and judging whether the absolute values exceed the preset threshold value;
if the difference value exceeds the preset expansion step length, recording the current time node, if the difference value does not exceed the preset expansion step length, expanding the detection time window, and recalculating the absolute value of the maximum one-level MODWT detail coefficient difference value and the corresponding average value based on the expanded detection time window.
It is understood that MODWT is an abbreviation of Maximal overlay descriptor Wavelet Transform in English, i.e. the MLSS.
It should be noted that the wiring of each room can form a complete microgrid system. When a customer enters a certain room, the current time is recorded, and the line voltage data detection is triggered. Because customers may carry high-power equipment, if the customers plug the high-power equipment into an indoor socket, the risk of line blowing is easily caused, and once the line is blown, the indoor micro-grid system fails. When the circuit fault is monitored, the LED group can be prompted to carry out light alarm display, so that managers can conveniently investigate the potential safety hazard of each room from the outside.
It should be noted that the initial length and the expansion step size of the detection time window are preset, and the left end of the detection time window in the initial state is aligned with the moment when the customer enters the room for the first time. In the subsequent detection time window expansion process, the left end is unchanged, and the right end is increased according to the expansion step length. The adoption of an expanded detection time window is a simulation of real-time detection of indoor line voltage data. The initial running time of various indoor electric appliances (such as televisions, refrigerators, large-scale power equipment and the like) is equivalent to the initial length of a detection time window, when no fault is found in the detection time window, the step length is continuously expanded to increase the length of the detection time window, and detection is carried out until the voltage fault is detected in the detection time window.
According to the embodiment of the invention, after the LED group is subjected to light display according to the control information provided by the first internet of things device, the method further includes:
in historical time, acquiring light-off time of each room in the building, acquiring current season information and customer information of the corresponding room, and recording the current season information and the customer information in a historical database;
constructing a work and rest time prediction model, training the work and rest time prediction model by adopting data in a historical database, and optimizing model parameters;
at the current time, collecting the customer information of each room in the building and the current season information, inputting the current season information and the customer information of each room into the work and rest time prediction model, and predicting the light-off time of each room
Figure 533313DEST_PATH_IMAGE010
Wherein m is the total number of rooms that the building has customers to live in at the current time,
presetting the influence weight of the LED group on each room as
Figure 63389DEST_PATH_IMAGE011
Then the optimal time R for the LED group to turn off is calculated, and

，
Figure 672542DEST_PATH_IMAGE014
represents room identification information, and
Figure 377192DEST_PATH_IMAGE015
。
it should be noted that, usually, the LED group performs light display according to the control information provided by the first internet of things device (i.e., the controller), however, the sleep quality of the customers in the building may be affected by the exciting light (e.g., red light, blue light, etc.) while performing the light display. The invention can predict the light-off time of each room, and set the turn-off time of the LED group based on the light-off time of each room, so as to prevent the LED group from influencing the normal sleep of customers.
It is understood that the turn-off time of the LED group can only be derived from the predicted light-off time of each room, and usually the turn-off time of the LED group is between the earliest and latest light-off time.
Based on the design of the building structure or the layout design of the LED groups, the LED groups have different degrees of influence on the rooms, for example, the LED groups have a smaller degree of influence on some rooms and a larger degree of influence on other rooms. According to the invention, the influence weight is added to correct the closing time of the LED group, and the LED group is closed in the corrected closing time (namely the optimal time R), so that the comprehensive influence degree of the LED group on all customers can be reduced to the minimum.
According to the embodiment of the invention, the light display of the LED group is carried out according to the control information provided by the first Internet of things device, and the method specifically comprises the following steps:
acquiring meeting activity information within a preset distance around the building by the first Internet of things equipment through a big data platform;
identifying the types of the crowds participating in the meeting activities according to the meeting activity information;
formulating control information adapted to the crowd category by the first internet of things device;
and displaying the light of the LED group according to the control information matched with the crowd category.
