detailed description

Embodiments of the present invention firstly provide a home appliance control system based on indoor positioning. FIG. 1 is a schematic diagram of an indoor positioning-based home appliance control system according to an embodiment of the present invention. The indoor positioning home appliance control system includes a plurality of fixed Bluetooth modules 110 , a mobile terminal 200 , and a cloud server 300 . Wherein a plurality of fixed Bluetooth modules 110 can be respectively arranged in a plurality of home appliances 100 in the positioning area, such as water heaters, indoor units of air conditioners, refrigerators, audio-visual equipment, water heaters, lamps and other home appliances arranged in indoor spaces such as homes and shopping malls. within 100. The mobile terminal 200 is configured with a mobile Bluetooth module 110 for receiving broadcast signals sent by the fixed Bluetooth module 110 .

Multiple fixed bluetooth modules 110 are configured to continuously send broadcast signals. Under ideal conditions, one fixed bluetooth module 110 sends broadcast signals. It is inversely proportional. In the actual use environment, because the signal transmission environment conditions are quite different from the ideal situation, the same mathematical model above cannot be simply used to express the relationship between signal strength and distance. This is why distance calculations using signal attenuation are less accurate as distance increases.

In areas with complex terrain or inside buildings, wireless signal transmission is dependent on terrain and propagation obstacles, so it presents a very strong specificity of receiving sites. Therefore, for each receiving point, the multipath structure of the channel is unique to each location. Therefore, in the positioning area, the signal strength of the broadcast signal received by each location generally does not strictly follow the general law that the signal strength gradually decays with the distance from the signal source, but will show a dependence on the unique transmission environment of the area. sex. Utilizing this particularity, signal fingerprints of broadcast signals of multiple fixed Bluetooth modules 110 within the positioning area can be collected.

The number of multiple fixed bluetooth modules 110 can be configured according to the situation of the location area, and it is generally required that each location in the location area can receive broadcast signals from at least three fixed bluetooth modules 110 .

The mobile terminal 200 is carried by the user, so that the position of the mobile Bluetooth module 110 is consistent with the position of the mobile terminal 200. The mobile Bluetooth module 110 and the fixed Bluetooth module 110 can use the same transmission mode, so that the above-mentioned broadcast signal can be received. The Signal Strength Indication (Received SignalStrength Indication, RSSI for short) is related to the location. The mobile terminal 200 can extract signal features according to the broadcast signal received by the mobile Bluetooth module 110 .

The mobile Bluetooth module 110 and the fixed Bluetooth module 110 use Bluetooth Low Energy technology (Bluetooth Low Energy, also known as Bluetooth 4.0 or Bluetooth Smart) to send and receive broadcast signals. Each fixed bluetooth module 110 is configured with a unique identification code, and the above-mentioned identification code is included in the broadcast signal sent by it, so as to distinguish the broadcast signal sent by the fixed bluetooth module 110 . Correspondingly, the signal features extracted by the mobile terminal 200 may include: the identification code of each fixed Bluetooth module 110 and the signal strength of its broadcast signal.

Bluetooth 4.0 is a wireless communication technology that uses microwave wireless communication technology to complete point-to-point or point-to-multipoint short-distance communication. Using Bluetooth technology, multiple devices can be connected into a piconet, and multiple piconets can be further interconnected to form a larger distributed network. Bluetooth 4.0 is the latest version of Bluetooth. Compared with the previous version, it is more power-saving, has the characteristics of low cost, 3 milliseconds low delay, and long effective connection distance.

The cloud server 300 is respectively connected to the network with the mobile terminal 200 and a plurality of home appliances 100, and performs data transmission, for example, through Wi-Fi or the like. In FIG. 1 , network devices in the network connection, such as wireless routers, switches, base stations, etc., are omitted. The cloud server 300 may first store a signal fingerprint database formed according to the above-mentioned signal fingerprints, so as to perform positioning data matching. The cloud server 300 can obtain the signal features uploaded by the mobile terminal 200, and match the signal features with the signal fingerprint library of the preset positioning area, so as to determine the user's location.

The cloud server 300 may store the pre-configured control instructions and control parameters of the above-mentioned multiple household appliances 100, and after determining the location of the user, it may send corresponding control instructions to the multiple household appliances 100 according to the location of the user, so as to The respective working states of the plurality of home appliances 100 are adjusted. The working status of the specific adjustment may include adjusting the switch, wind force and wind direction of the air conditioner; adjusting the switch and volume of audio-visual equipment; adjusting the switch and brightness of the light; and adjusting the switch and water temperature of the water heater. For example, the air-conditioning indoor unit around the user can be controlled to blow air around the user, or the audio-visual equipment can be turned off after the user leaves the play area of the audio-visual equipment; the water heater and light can be turned on after the user enters the room. The specific control strategy can be configured in advance.

In addition, the control of the above home appliances 100 can also be performed by the mobile terminal 200, for example, the cloud server 300 returns the determined location information to the mobile terminal 200, and the mobile terminal 200 sends corresponding control signals to surrounding home appliances. In a preferred embodiment, the mobile terminal 200 can also send control instructions to the fixed Bluetooth module 110 of the corresponding home appliance 100 through the mobile Bluetooth module 110 in Bluetooth mode, that is, the fixed Bluetooth module 110 can complete the broadcast signal of the positioning system. The sending function can also serve as a communication interface of the household electrical appliance 100 .

An optional execution method for the cloud server 300 to determine the location is: determine a plurality of location points closest to the signal features from the signal fingerprint database, and calculate the average value of the coordinates of the location points to obtain the coordinates of the user's location , and return the coordinates of the user's location to the mobile terminal 200 .

The mobile terminal 200 can also display the user's location on the electronic map of the positioning area according to the coordinates. The electronic map can intuitively display the internal precise location information of large indoor places such as commercial facilities, transportation facilities, performance venues, and warehouses. Thus, it is convenient for users to receive services such as indoor navigation and information push by using the electronic map and their location.

In addition, the mobile terminal 200 can also accept the user's selection operation on the position of the electronic map, extract the user's correction of its position, generate correction feedback, and upload the correction feedback to the cloud server 300, so that the cloud server 300 can follow the user's correction. , to update the signal fingerprint database.

The mobile terminal 200 can also be provided with GPS modules such as Global Positioning System (Global Positioning System, usually referred to as GPS), Beidou system (or other modules that realize satellite positioning, such as positioning components such as Beidou system), for positioning in an outdoor open environment. Use the positioning system established by the geostationary satellite for positioning. The mobile terminal 200 can upload the GPS coordinates to the cloud server 300 . The cloud server 300 is further configured to: determine the position information of the positioning area according to the global positioning system coordinates, and the position information includes the geographic coordinates of the positioning area and the identification of the positioning area. The electronic map of the mobile terminal 200 can combine the indoor map and the outdoor electronic map, and switch according to the location. When entering the indoor scene, switch the location of the outdoor building to the structure inside the building. Provide users with a full range of positioning services.

The embodiment of the present invention also provides a home appliance control method based on indoor positioning. The home appliance control method based on indoor positioning can be executed by the cloud server 300 in the above-mentioned home appliance control system to use the user's position in the positioning area to Intelligent control of household appliances 100. Fig. 2 is a schematic diagram of an indoor positioning-based home appliance control method according to an embodiment of the present invention, and the indoor positioning-based home appliance control method may generally include:

Step S202, acquire the signal feature uploaded by the mobile terminal 200 carried by the user, the signal feature is obtained according to the broadcast signal received by the mobile Bluetooth module 110 of the mobile terminal 200 from multiple fixed Bluetooth modules 110 in the positioning area, And a plurality of fixed bluetooth modules 110 are respectively arranged in a plurality of home appliances 100 within the location area. Each fixed Bluetooth module 110 can be configured with a unique identification code, and the signal characteristics include: the identification code of each fixed Bluetooth module 110 and the signal strength of its broadcast signal, preferably the above fixed Bluetooth module 110 and mobile Bluetooth module 110 can be respectively Use Bluetooth 4.0 module.

Step S204, matching the signal features with the signal fingerprint library of the preset positioning area to determine the user's location. The signal fingerprint library stores signal features corresponding to different positions in the positioning area. Since the signal fingerprint library stores the signal features of several positions in the positioning area, it is impossible to cover every point in the positioning area strictly, so when performing position matching, multiple positions closest to the signal features can be determined from the signal fingerprint library point; calculate the average value of the coordinates of the location points to obtain the coordinates of the user's location.

Step S206 , sending corresponding control commands to the plurality of household electrical appliances 100 according to the location of the user, so as to adjust the respective working states of the plurality of household electrical appliances 100 . Adjusting the respective working states of multiple home appliances 100 includes any one or more of the following: adjusting the switch, wind force and wind direction of the air conditioner; adjusting the switch and volume of audio-visual equipment; adjusting the switch and brightness of the light; and adjusting the switch and water temperature of the water heater . In a specific usage environment, the control strategy of the household electrical appliance 100 may be configured according to the type of the configured household electrical appliance 100 and the usage requirements of the user. The above household electrical appliance 100 is only an example of this embodiment, and does not limit the present invention.

The above signal fingerprint library can be obtained by measuring and summarizing the signal characteristics of the actual environment in advance in the positioning area. In addition, according to the actual characteristics of different positioning areas, different methods can be used to generate and calibrate the signal fingerprint library.

Fig. 3 is a flow chart of initializing and generating a signal fingerprint library in an indoor positioning-based home appliance control method according to an embodiment of the present invention, the initial generating process of the signal fingerprint library includes:

Step S302, acquiring an electronic map of the positioning area;

Step S304, receiving the position of the fixed Bluetooth module 110 marked on the electronic map;

Step S306, generating a signal fingerprint library according to the calibration position according to the RSSI attenuation model;

Step S308, according to receiving the location of the fixed Bluetooth module 110 marked on the electronic map.

The above initial generation process of the signal fingerprint database can be applied to positioning areas with fewer signal transmission obstacles and larger areas such as shopping malls. The RSSI and the distance from the positioning position to the signal transmitting source can generally meet the requirement of RSSI=A-10nlg(d). In addition, when updating the signal fingerprint library, it is necessary to filter the position information of the correction feedback, and filter out the position feedback that obviously exceeds the positioning area or is obviously wrong.

Fig. 4 is a flow chart of another initialization generation of the signal fingerprint library in the indoor positioning-based home appliance control method according to an embodiment of the present invention, the initial generation process of the signal fingerprint library includes:

Step S402, acquiring an electronic map of the positioning area;

Step S404, receiving the position of the fixed Bluetooth module 110 marked on the electronic map;

Step S406, receiving signal features collected by the user at several locations;

Step S408, using several position points to perform smoothing processing to form a signal fingerprint database.

The initial generation process of the signal fingerprint database can be applied to positioning areas where the area of the home is small but there are many transmission obstacles such as walls. For example, the user can collect one or several points in each room, and use the signal features of these collected points as the calibration points of the room to generate a signal fingerprint library for the entire room. In actual use, the location of the fixed Bluetooth module 110 marked on the electronic map may also be received.

In addition to the two methods described above, the cloud server 300 can also perform matching from the existing signal fingerprint library according to the characteristics of the positioning area and the position of the fixed Bluetooth module 110, so as to use the matching result as the initial signal of the positioning area Fingerprint library. Further, the mobile terminal 200 may also preset signal fingerprint libraries of multiple commonly used positioning areas, so as to implement location matching locally on the mobile terminal 200 .

Each positioning area can also be calibrated by coordinates, for example, using a European coordinate system, setting the origin of the coordinates, and sequentially calibrate the position of the fixed Bluetooth module 110 through a three-point positioning method. In addition, the coordinates of each positioning area are also associated with GPS information to achieve comprehensive positioning indoors and outdoors. For example, the mobile terminal 200 is also provided with a GPS module, and is configured to upload the global positioning system coordinates to the cloud server 300; the cloud server 300 is also configured to determine the position information of the positioning area according to the global positioning system coordinates, and the position information includes the geographic coordinates of the positioning area and The ID of the targeting area. For example, when the GPS is used to determine that the user enters a certain positioning area, the indoor positioning of the positioning area is automatically turned on. The mobile bluetooth module 110 in the mobile terminal 200 starts up and enters the indoor positioning process.

The home appliance control method based on indoor positioning in this embodiment can also provide users with location services such as navigation and information provision. For example, after obtaining the coordinates of the user's location, it also includes: returning the user's location to the mobile terminal 200 The coordinates of the location are used for the mobile terminal 200 to display the user's location on the electronic map of the positioning area according to the coordinates. The electronic map can also be used to realize functions such as indoor location navigation and popular location recommendation.

In the home appliance control method based on indoor positioning in this embodiment, the mobile Bluetooth module 110 can also send control instructions to the fixed Bluetooth module 110 of the corresponding home appliance device 100 in Bluetooth mode, that is, the fixed Bluetooth module 110 can complete the broadcast signal of the positioning system. The sending function can also serve as a communication interface of the household electrical appliance 100 .

FIG. 5 is a flow chart of an application example of positioning in an indoor positioning-based home appliance control method according to an embodiment of the present invention. The entire positioning process may include the following steps:

Step S502, modeling the sample database. For example, the fingerprint sample space is established by fixing the attenuation model of the transmission power of the Bluetooth module 110 in space, that is, using the mapping relationship between RSSI and position (RSSI=A-10nlg(d)) to carry out signal fingerprint modeling;

Step S504, collecting instance location data. In an indoor environment where at least three fixed Bluetooth modules 110 are installed, the instance positions of multiple measurements are matched with the sample data and repeatedly corrected to form an initialized set of fingerprint identification data for calibrating a specific room;

Step S506, calibrate the relative position coordinates. After initializing the instance location data, set the relative location coordinates. For example, the Euclidean coordinate system is used to select a coordinate origin, and the relative position of the fixed Bluetooth module 110 is calibrated sequentially through the three-point positioning rule. When determining the GPS position of the positioning area itself, it can be associated with other indoor positioning sets to form an urban area positioning system. ;

Step S508, real-time positioning. When the mobile terminal 200 with the mobile Bluetooth module 110 enters the effective range of the initialized base station, the mobile Bluetooth module 110 will automatically receive the broadcast signal sent by the fixed Bluetooth module 110, and determine the identification and signal contained in the broadcast signal intensity to form the signal signature. The mobile terminal 200 reports the received signal characteristics to the cloud server 300 . The cloud server 300 will match the reported signal features with the instantiated signal fingerprint library of the indoor positioning area. The matching algorithm can take the average value of multiple closer matching results, and then perform coordinate conversion on the obtained results to determine the real-time position coordinate data, and the cloud server 300 will return the position coordinate data to the mobile terminal 200 for display.

In addition, the cloud server 300 can also perform intelligent control of home appliances according to the user's location and provide location-based services such as indoor navigation.

Step S510, position calibration. If the real-time location information obtained by the user is not accurate enough, fine-tuning can be performed on the electronic map of the mobile terminal 200 (generally, the adjustment in the range of 20-100cm is done on the original position), and the position feedback data determined according to the fine-tuning is reported to the cloud server After 300, after filtering (filtering out the data beyond the moving range), it is updated into the instantiated fingerprint database by means of cumulative average for subsequent position matching.

The home appliance control method based on indoor positioning of the present invention applies the Bluetooth 4.0 technology to the home appliance 100 for indoor positioning, relies on the smart home appliance cloud platform to quickly realize the positioning technology, and uses the offline fingerprint sample training model combined with the target online real-time positioning This method effectively reduces the amount of computation in positioning and saves time. Using the signal fingerprint database can better approach the specific indoor positioning environment, and reduce the impact of RSSI reception on electromagnetic interference, reflection, and multipath effects in the environment. In addition, user feedback can also be used for calibration to optimize the actual measurement position error caused by changes in the indoor environment over time and space, thereby improving positioning accuracy.

The home appliance control method and home appliance control system based on indoor positioning in this embodiment utilize low-power bluetooth technology to achieve precise indoor positioning. The automatic adjustment of the state of the home appliance meets the requirements of the user and improves the intelligence and efficiency of the home appliance. The Bluetooth module can be integrated in home appliances as a fixed node for broadcasting and sending positioning signals. Using the characteristics that Bluetooth signals are dependent on indoor space and obstacles encountered during propagation, the pre-generated signal fingerprint library has saved the positions and signals of the positioning area. The corresponding relationship of features, so as to use the signal fingerprint library to realize the location query, reduce the influence of electromagnetic interference, reflection, multipath effect, etc., and the positioning accuracy is high.
