Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a method for transmitting positioning information, and a specific flow is shown in fig. 1. The positioning information transmission method in the embodiment is implemented on intelligent equipment, and the intelligent equipment can be intelligent lighting equipment (such as an intelligent bulb), an intelligent ground mat, an intelligent switch and the like. The following describes specific implementation steps of the positioning information transmission method in this embodiment:
Specifically, the broadcasting device can be a mobile terminal such as a wireless tag, a mobile phone, a bracelet, a tablet computer, and the like, and is convenient for a user to carry about.
More specifically, the broadcasting device broadcasts a data packet, and the data packet may include device information of the broadcasting device and signal transmission power. When the intelligent equipment receives the data packet, the signal receiving power when the data packet is obtained is detected, and the received signal strength RSSI value is obtained according to the signal receiving power and the signal sending power contained in the data packet.
Specifically, after receiving a data packet broadcast by the broadcasting equipment, the intelligent equipment sends a connection request to the broadcasting equipment according to the equipment information in the data packet, and establishes wireless communication connection with the broadcasting equipment. The wireless communication connection established between the intelligent device and the broadcasting device can be a mobile wireless network connection, a wireless fidelity network connection, a Bluetooth network connection and the like.
More specifically, the intelligent device establishes the wireless communication connection with the broadcasting device only when the time interval between the time point of the last connection establishment with the broadcasting device and the current time point is determined to be greater than the preset time, so that the intelligent device can be prevented from being connected with the broadcasting device too frequently, the power consumption of the intelligent device can be reduced, and the connection pressure of the broadcasting device can be reduced. The preset time period may be preset by a technician, for example, the preset time period may be 1 second.
Specifically, the obtaining manner of the cache threshold value may be: and the broadcasting equipment sends all the currently cached RSSI values to the intelligent equipment so that the intelligent equipment can set and acquire the caching threshold value of the broadcasting equipment. For example, the intelligent device sets an acquisition buffer threshold value according to an initial preset threshold value of the broadcasting device and all currently buffered received signal strength RSSI values, when the number of currently buffered received signal strength RSSI values of the broadcasting device is less than the initial preset threshold value, the buffer threshold value is ∞, and when the number of currently buffered received signal strength RSSI values of the broadcasting device reaches the initial preset threshold value, the buffer threshold value is equal to the lowest currently buffered received signal strength RSSI value of the broadcasting device. The initial preset threshold may be 1, or may be preset by a technician according to a positioning algorithm in the positioning server, for example, when the positioning algorithm in the positioning server is a triangulation algorithm, the initial preset threshold may be 3.
More specifically, the obtaining manner of the cache threshold value may further be: and the broadcasting equipment generates a cache threshold value according to all the currently cached RSSI values and sends the cache threshold value to the intelligent equipment.
The following illustrates a specific implementation form of step 103 in this embodiment:
(1) the initial preset threshold value is 3, and if the broadcasting equipment actually caches 2 RSSI values at present, the caching threshold value of the broadcasting equipment acquired by the intelligent equipment is- ∞.
(2) The initial preset threshold value is 3, the broadcasting equipment actually caches 3 RSSI values at present, which are-59, -60, -70 respectively, and then the caching threshold value of the broadcasting equipment acquired by the intelligent equipment is-70. If the RSSI value of the smart device is-65, the determination result in step 102 is yes. If the RSSI value of the received signal strength of the smart device is-71, the determination result in step 102 is no.
Specifically, the clear instruction is used to control the broadcasting device to delete each overtime RSSI value among all currently cached RSSI values and the corresponding device information. In this way, the broadcaster can be enabled to clear the time-out, invalid information in a timely manner to make room for the storage of subsequent RSSI values.
It should be noted that the broadcasting device may also detect whether an overtime received signal strength RSSI value exists in all currently cached received signal strength RSSI values by itself, and if it is detected that an overtime received signal strength RSSI value exists in all currently cached received signal strength RSSI values, delete the overtime received signal strength RSSI value and the corresponding device information, so as to also implement timely cleaning of the overtime and invalid information and free up a location for storing a subsequent RSSI value. Based on this, step 104 may be omitted if the broadcasting device has a function of self-cleaning data.
And 105, sending the received signal strength RSSI value and the own equipment information to the broadcasting equipment for caching.
Specifically, the smart device sends the RSSI value and its own device information to the broadcasting device through the established wireless communication connection, so that the broadcasting device deletes the lowest RSSI value currently cached and its corresponding device information, and caches the device information and the RSSI value of the smart device as a set of correspondence (that is, all the RSSI values currently cached by the broadcasting device and all the device information are one correspondence between the RSSI values and the device information). The device information of the intelligent device may be a unique identification code of the intelligent device, such as a hardware address of the intelligent device or a device number of the intelligent device in the internet of things system.
In this embodiment, after caching the device information and the received signal strength RSSI value of the smart device, the broadcasting device may filter and screen the currently cached received signal strength RSSI value and the device information. For example, the broadcasting device may only store the maximum RSSI value and the device information thereof if only one RSSI value with the maximum RSSI value exists among all the RSSI values currently cached by the broadcasting device, and the other RSSI values with the maximum RSSI value are equal. That is, the RSSI value of the received signal strength buffered by the broadcasting device and the amount of the device information may be determined according to actual situations. The following are exemplified:
as shown in fig. 2, the smart devices a1, a2, and A3 are smart bulbs, a2 and A3 are symmetrically disposed on both sides of the smart device a1, and the broadcasting device B1 is located right below the smart device a 1. RSSI1 represents the received signal strength RSSI value between smart device a1 and broadcaster B1; RSSI2 represents the received signal strength RSSI value between smart device a2 and broadcaster B2; RSSI3 represents the received signal strength RSSI value between smart device A3 and broadcaster B3. As can be seen from fig. 2, RSSI2 and RSSI3 are equal, and RSSI1 is greater than RSSI2 and RSSI 3. At this time, the location of the smart device a1 is the location of the broadcasting device B1, so the RSSI value actually cached by the broadcasting device may be only RSSI1, and thus, there is less data to be transmitted between the broadcasting device and the smart device, less data to be uploaded by the smart device, and less data processing pressure of the location server.
However, the example in fig. 2 is only an exemplary illustration, and the embodiment does not limit how the broadcasting device processes the buffered RSSI value.
And step 106, acquiring all received signal strength RSSI values and all equipment information currently cached by the broadcasting equipment, and uploading to a preset positioning server.
Specifically, the intelligent device transmits all received signal strength RSSI values and all device information sent by the broadcasting device to the gateway through the MESH network of the wireless MESH of the internet of things system, so as to be conveniently transferred to the preset positioning server through the gateway. The technical staff or the user can perform simple configuration on the gateway in advance, so that the gateway can guide the data to a preset positioning server for calculation.
In this embodiment, after acquiring the RSSI value sent by the smart device, the broadcasting device may detect whether the RSSI value is the maximum value among all the RSSI values currently cached. If the RSSI value is the maximum value of all the RSSI values cached currently, the broadcasting equipment transmits all the RSSI values cached currently and all the equipment information to the intelligent equipment. Or, after acquiring all the received signal strength RSSI values and all the device information currently cached by the broadcasting device, the intelligent device may further detect whether the received signal strength RSSI value between itself and the broadcasting device is the maximum value among all the received signal strength RSSI values currently cached by the broadcasting device, and perform the uploading step only when detecting that the received signal strength RSSI value is the maximum value among all the received signal strength RSSI values. Therefore, the positioning server can be prevented from receiving too much invalid and repeated data information, the data processing pressure of the positioning server is further reduced, and the positioning efficiency is improved.
For example, all the RSSI values currently buffered by the broadcasting device and all the device information may be as shown in the following table one:
watch 1
| Device numbering | RSSI value |
| 1 | -59 |
| 2 | -60 |
| 3 | -70 |
As can be seen from table one, the smart device with device number 1 is closest to the broadcasting device among the three smart devices in table one; the smart device with device number 3 is the farthest from the broadcaster of the three smart devices in table one. The positioning server may obtain the position coordinates of the smart device with the device number 1, the position coordinates of the smart device with the device number 2, and the position coordinates of the smart device with the device number 3 according to a pre-stored positioning algorithm (such as a triangulation algorithm) and a correspondence between the device information and the position coordinates, thereby positioning the broadcasting device.
It should be noted that, if the broadcasting device is a bluetooth tag, a mobile phone with a bluetooth function, a bracelet, or the like, the wireless communication connection established between the smart device and the broadcasting device may be a bluetooth low energy (bluetooth) Generic Attribute Profile (GATT) connection. Therefore, information interaction between the intelligent equipment and the broadcasting equipment is transmitted through the data channel, the load of the broadcasting channel can be reduced, and the conditions of congestion, low transmission efficiency and serious packet loss of the broadcasting channel are avoided. In addition, although the length of the data transmitted by the bluetooth data channel is limited, in this embodiment, only a very small number of RSSI values and device information need to be transmitted, so that the GATT connection can be established to meet the data transmission requirements in this embodiment.
Compared with the prior art, the embodiment of the invention has the advantages that the intelligent device sends the received signal strength RSSI value and the self device information to the broadcasting device for caching when the received signal strength RSSI value is greater than or equal to the caching threshold value of the broadcasting device, namely, the received signal strength RSSI values of all the intelligent devices in the Internet of things system are screened, and the larger received signal strength RSSI value can be cached in the broadcasting device. Therefore, the intelligent equipment transmits the RSSI value and the equipment information of each received signal strength cached by the broadcasting equipment to the positioning server for positioning, so that the positioning information received by the positioning server is simplified and effective, the data processing pressure of the positioning server is reduced, and the positioning efficiency is improved. By the method, the intelligent equipment for sending the information to the positioning server is screened, so that all the intelligent equipment are not required to transmit the information to the positioning server, the network bandwidth is saved, and the number of the broadcasting equipment which can be positioned under the same network condition is increased.
A second embodiment of the present invention relates to a positioning information transmission method. The second embodiment is improved on the basis of the first embodiment, and the main improvement lies in that: in the second embodiment of the present invention, the intelligent device further uploads the mobile information of the broadcasting device to the positioning server, so as to provide a data base for the positioning server to obtain a positioning result with higher accuracy.
Specifically, if the determination result in step 103 is yes, the smart device uploads the movement information to a preset positioning server when receiving the movement information sent by the broadcasting device, so that the positioning server performs positioning calibration on the broadcasting device according to the movement information. Therefore, the positioning server can acquire a more accurate positioning result, and can prevent all intelligent devices from sending the received mobile information to the positioning server, so that the positioning server receives too many repeated mobile information, thereby effectively reducing the data processing pressure of the positioning server and improving the positioning efficiency.
More specifically, the broadcasting device may be provided with sensors such as an accelerator, a gyroscope, and the like, by which the broadcasting device monitors whether it is moving and generates movement information. And, the broadcasting equipment can transmit the mobile information in a broadcasting form, so that the intelligent equipment can receive the mobile information broadcasted by the broadcasting equipment.
In actual operation, the uploading condition of the mobile information can be increased, for example, the intelligent device uploads the mobile information to a preset positioning server when detecting that the RSSI value is the maximum value of all RSSI values cached by the broadcasting device currently, so that the positioning server can be further prevented from receiving too many repeated mobile information, the data processing pressure of the positioning server is effectively reduced, and the positioning efficiency is improved.
Compared with the first embodiment, the positioning information transmission method in the present embodiment can obtain a more accurate positioning result even when the user moves, and the application range is wider.
A third embodiment of the present invention relates to a method for transmitting positioning information, and a specific flow is shown in fig. 3. The positioning information transmission method in the embodiment is implemented on broadcasting equipment, and the broadcasting equipment can be a mobile terminal such as a wireless tag, a mobile phone, a bracelet, a tablet computer and the like. The following describes specific implementation steps of the positioning information transmission method in this embodiment:
Specifically, the broadcasting device broadcasts a data packet, and the data packet may include device information of the broadcasting device and signal transmission power. When the intelligent equipment receives the data packet, the signal receiving power when the data packet is obtained is detected, and the received signal strength RSSI value is obtained according to the signal receiving power and the signal sending power contained in the data packet. And the intelligent equipment sends a connection request to the broadcasting equipment according to the equipment information in the data packet, and establishes wireless communication connection with the broadcasting equipment. The wireless communication connection established between the intelligent device and the broadcasting device can be a mobile wireless network connection, a wireless fidelity network connection, a Bluetooth network connection and the like.
In this embodiment, the broadcast device generates the buffer threshold value. If the number of the currently cached RSSI values of the received signal strength is smaller than an initial preset threshold value, setting the caching threshold value to- ∞, and if the number of the currently cached RSSI values reaches the initial preset threshold value, setting the caching threshold value to be the lowest RSSI value currently cached. The initial preset threshold may be preset by a technician and stored in the broadcasting device, for example, the initial preset threshold may be 1. In actual use, a technician may set an initial preset threshold according to a positioning algorithm in the positioning server, for example, when the positioning algorithm in the positioning server is a triangulation algorithm, the initial preset threshold is 3.
Specifically, the broadcasting device deletes the lowest RSSI value and the device information corresponding thereto, which are currently cached, and caches the device information of the smart device and the RSSI value as a set of correspondence. The device information of the intelligent device may be a unique identification code of the intelligent device, such as a hardware address of the intelligent device or a device number of the intelligent device in the internet of things system.
More specifically, the broadcasting device may filter the currently buffered RSSI values and the device information. For example, the broadcasting device may only store the maximum RSSI value and the device information thereof if only one RSSI value with the maximum RSSI value exists among all the RSSI values currently cached by the broadcasting device, and the other RSSI values with the maximum RSSI value are equal. That is, the broadcasting device may perform certain processing on the buffered RSSI value.
And step 204, sending all the currently cached RSSI values and all the equipment information to the intelligent equipment.
Specifically, the broadcasting device sends all currently buffered RSSI values and all device information to the smart device through the wireless communication connection established in step 201.
In this embodiment, the technical staff sets the broadcasting equipment to have a data self-cleaning function, for example, the broadcasting equipment detects whether an overtime received signal strength RSSI value exists in all currently cached received signal strength RSSI values, and if it is detected that an overtime received signal strength RSSI value exists in all currently cached received signal strength RSSI values, the overtime received signal strength RSSI value and the corresponding equipment information are deleted, so as to clear the overtime and invalid information in time and vacate a position for storing a subsequent RSSI value. Wherein the time value of whether the broadcast equipment measures time out can be preset by a technician.
In actual operation, the technician may also set that the intelligent device sends a cleaning instruction to the broadcasting device after determining whether the received signal strength RSSI value is greater than or equal to the cache threshold value of the broadcasting device, so that the broadcasting device deletes each overtime received signal strength RSSI value and the corresponding device information in all currently cached received signal strength RSSI values according to the cleaning instruction. It also enables the broadcaster to clear timely the overtime, invalid information in order to make room for the storage of subsequent RSSI values.
Therefore, the broadcasting equipment can clear all the received signal strength RSSI values and all the equipment information which are cached at present by self, and can also passively clear all the received signal strength RSSI values and all the equipment information which are cached at present when a clearing instruction sent by the intelligent equipment is received. In this regard, the present embodiment is not limited at all.
It should be noted that, after acquiring the RSSI value of the received signal strength sent by the smart device, the broadcasting device may detect whether the RSSI value of the received signal strength is the maximum value among all the RSSI values currently cached.
