Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

It will be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element.

As shown in FIG. 1 , NFC (Near Field Communication, near field wireless communication) communication adopts a polling mechanism. There are two working modes of NFC polling: Polling (active scanning mode) and Listening (passive listening mode). Among them, in the active scanning mode, the NFC will transmit the search frame signals Type A/B/F/V in turn in the polling mode; in the passive listening mode, the NFC is in the standby state or the listening mode. NFC specifies 5 different types of cards according to the four communication interface protocols of Type A/B/F/V, including:

(1) Type 1 tag (Tag1): Based on the ISO14443A standard, it has the ability to read and rewrite, the storage capacity is 96 bytes, the memory can be expanded to 2K bytes, the communication speed is 106Kbit/s, and the cost is relatively low Low;

(2) Type 2 tag (Tag2): Based on the ISO14443A standard, it has the ability to read and rewrite, the storage capacity is 48 bytes, the memory can be expanded to 2K bytes, and the communication speed is 106Kbit/s;

(3) The third type of tag (Tag3): Based on the Sony Felica system, the memory is 2K bytes, and the data communication speed is 212Kbit/s, which is suitable for more complex applications;

(4) Category 4 tags (Tag4): Compatible with ISO14443A and B standards, the memory is 32K bytes, and the communication speed is between 106Kbit/s and 424Kbit/s;

(5) Category 5 tag (Tag5): Type V standard defined by NFC Forum, based on ISO15693 specification, communication rate 106kbit/s, mostly used in logistics and warehousing industry.

The characteristics of different Type cards correspond to different usage scenarios. For example, in China, in addition to Type B cards for ID cards, most other cards such as bus cards, bank cards, and work cards are Type A cards, warehousing and logistics are Type V cards, and Type F cards. Type B cards are rarely used; in Singapore, Type B cards are widely used; in Japan and Hong Kong, Type F cards are widely used, and so on.

In this embodiment of the present application, GPS (Global Positioning System, global positioning system) positioning information can be used to determine the area code where the NFC device is located, and the area code is used to automatically identify the area where the user is located. The scan parameters of each communication type Type A/B/F/V are re-optimized and configured with appropriate weights, and the scan parameters include at least one of scan duration or scan order. For example, if it is found in China through country code positioning, then the proportion of A\B\F\V types used in China collected according to big data, for example, with 1 as the total amount, the proportion is 0.6:0.1:0.02:0.28, Then the proportions of A\B\F\V in the polling stage as shown in Figure 1 can be re-customized from the previous equal share, and the time proportion of types B and F can be relatively reduced, so as to shorten the duration of the total polling stage. Another example is in Singapore, where the communication type of Type B card is widely used, the corresponding communication type is Type A\F\V type, and the time proportion in the polling stage should be greatly reduced, which can greatly reduce the amount of time spent in polling. The time of the small total polling phase is used to save power consumption.

FIG. 2 is a schematic flowchart of a control method of a near-field wireless communication device in one embodiment. As shown in Figure 2, a method for controlling a near-field wireless communication device includes:

Step 202: Obtain current geographic location information of the near-field wireless communication device.

Wherein, the near field wireless communication device, that is, the NFC device may be a device including an NFC device, such as a smart phone, an ipad, a digital assistant, a tablet computer, a POS machine, a wearable device, and the like. Wearable devices such as smart watches, smart glasses, head-mounted devices, etc.

Specifically, the NFC device can obtain the current geographic location information through its own GPS, or an auxiliary device with a distance from the NFC device within a preset range, obtain the current geographic location information of the auxiliary device through the locator of the auxiliary device, and use the locator of the auxiliary device to obtain the current geographic location information of the auxiliary device. The location information is used as the current location information of the NFC device. The preset range is usually relatively small, such as a range of 10 meters, a range of 1 meter, and the like. The geographic location information may be latitude and longitude coordinates or area address information or area code. For example, the latitude and longitude coordinates are 114°15' east longitude and 22°15' north latitude. The regional address information is Hong Kong, China. An area code can be a code that uniquely identifies the area. The region may be a country or a region, or the like.

Step 204: Determine a near field wireless communication NFC configuration file corresponding to the current geographic location information, where the NFC configuration file includes scanning parameter values of each communication type of the near field wireless communication device in the active scanning mode.

Specifically, the corresponding relationship between the geographic location information and the NFC configuration file can be established in advance, and the NFC configuration file includes the scanning parameter values of each communication type of the near-field wireless communication device in the active scanning mode, and then based on the current geographic location information The corresponding NFC configuration file is determined from the corresponding relationship, that is, the scanning parameter value of each communication type of the near-field wireless communication device in the active scanning mode under the current geographic location information is determined. The communication types in the active scanning mode may include Type A, Type B, Type F, Type V, and so on. The scan parameter value may include at least one of scan duration or scan order. The scan duration, that is, the scan time slot, also called the scan duty cycle, may be 20mm (milliseconds), 50mm, and the like. In other embodiments, the scan duration may be represented by a proportional value to the active scan duration, for example, Type A accounts for one quarter of the active scan duration. The scanning sequence refers to the scanning sequence of each communication type in one polling cycle, and the scanning sequence may be the first, the second, the third, the fourth, and so on. For example, the scan sequence is Type A\B\F\V, or Type B\A\F\V, etc.

The scanning duration of each communication type in the active scanning mode refers to the effective duration of waiting for a response signal after transmitting a signal of a certain communication type, and the response signal received within this scanning duration is valid, indicating that there is a corresponding device or card nearby detected. . For example, the scan duration of Type A is 5 milliseconds, the scan duration of Type B is 5 milliseconds, the scan duration of Type F is 5 milliseconds, the scan duration of Type V is 5 milliseconds, and the scan sequence is Type A\B\F\V, then The NFC device first transmits a Type A signal to the surrounding area, and waits for a response within 10 milliseconds. If no response is received, it transmits a Type B signal and waits for a response within 5 milliseconds. If no response is received, it continues to transmit a Type F signal. Wait for a response within 5 milliseconds, if no response is received, transmit the Type V signal, wait for a response within 5 milliseconds, end one polling cycle, start the next polling cycle, and start scanning from the Type A signal. The scan duration of each communication type can be the same or different.

Under different geographic location information, the scanning duration of each communication type can be configured to be different, and the scanning sequence of each communication type can also be different.

In one embodiment, the corresponding relationship between the area and the scanning parameter values of each communication type of the near-field wireless communication device in the active scanning mode may also be established in advance, and after obtaining the current geographic location information, determine the location where the current geographic location information is located. area, and then acquire the scan parameter values of each communication type of the corresponding near-field wireless communication device in the active scan mode. The area can be represented by an area code or by an area name.

Step 206, configure the near field wireless communication device according to the NFC configuration file corresponding to the current geographic location information.

Specifically, after the NFC device detects the NFC configuration file corresponding to the current geographic location information, that is, the scanning parameter values of each communication type in the active scanning mode corresponding to the current geographic location information, the NFC device configures the scanning parameter value of each communication type, and performs active scanning. scanning.

In this embodiment, by acquiring the current geographic location information of the NFC device, an NFC configuration file corresponding to the current geographic location information is determined. Active scanning can accurately configure the scanning parameter values of each communication type in the active scanning mode according to the geographic location, and can quickly scan the corresponding detected objects, which greatly reduces the active scanning time and saves power consumption. , and compared with the short duration inductively detecting whether there is an NFC-related tag card around, and then returning to the normal polling mode, the active scanning control method of the near-field wireless communication device in this embodiment does not have a delay. , which can meet scenarios with high delay requirements and avoid delay overhead.

In one embodiment, before acquiring the current geographic location information where the near-field wireless communication device is located, the method further includes:

Collect the usage ratio of each communication type in active scanning mode of near-field wireless communication devices in each area;

According to the usage ratio of each communication type of the near-field wireless communication device in each area in the active scanning mode, the corresponding relationship between the area and the NFC configuration file is generated, and the NFC configuration file includes each communication type of the near-field wireless communication device in the active scanning mode The scan parameter value of the communication type; wherein, the scan parameter value of the communication type is positively correlated with the usage ratio of the communication type.

Specifically, the usage data of each communication type of the near-field wireless communication devices in each area in the preset time period in the active scanning mode is collected in advance, and then statistical analysis is performed to obtain the communication types of the near-field wireless communication devices in each area in the active scanning mode. Type usage ratio. The preset time period can be set as required, for example, from January 1, 2019 to December 31, 2019, and from January 1, 2010 to December 31, 2019, etc., but not limited to this.

Regions can be administrative regions such as countries or regions or provinces or cities or towns. The sweep parameter value is positively correlated with the usage ratio, that is, the larger the usage ratio, the larger or higher the sweep parameter value is. If the scan parameter value is the scan duration, the larger the usage ratio, the longer the scan duration; if the scan parameter value is the scan order, the larger the usage ratio and the higher the scan order. Taking countries as an example, the usage data of each communication type Type A/B/F/V in the active scanning mode of NFC devices in different countries can be collected, and the usage ratio of each communication type Type A/B/F/V can be obtained by statistical analysis, such as In China, the proportion of each communication type Type A\B\F\V is 0.6:0.1:0.02:0.28, and the corresponding scan parameter value is configured according to the proportion of each communication type, and the scan duration of type A and type V is lengthened. , shorten the scanning duration of B and F types, and place the scanning order of type A first, the scanning order of V type second, the scanning order of B type third, and the scanning order of F type fourth bit, as shown in Figure 3.

Configure the corresponding NFC configuration file in the area, and perform active scanning, which is more in line with the use of NFC in the area, and can quickly detect the detected object, shorten the scanning time, and save power consumption.

In one embodiment, as shown in FIG. 4 , the usage and proportion of each communication type of the NFC device in the active scanning mode is collected by country or region to generate a corresponding NFC configuration file. The method for controlling a near-field wireless communication device in this embodiment includes:

Step 402, collecting the usage and proportion of each Type card in different countries or regions.

Specifically, the usage situation and usage ratio of each Type card in different countries or regions, that is, the usage situation and usage ratio of each communication type are collected. The usage ratio refers to the usage ratio of each communication type.

Step 404: Generate NFC configuration files corresponding to different country codes according to the usage and proportion of each Type card in different countries or regions.

The NFC configuration file includes scanning parameter values for each communication type of the near-field wireless communication device in the active scanning mode. The scan reference value may include at least one of scan duration or scan order.

According to the usage and proportion of each Type card in different countries or regions, the corresponding relationship between the country code and the NFC configuration file is generated.

Step 406, locate the country code where the NFC device is located according to the GPS, and call the corresponding NFC configuration file according to the country code.

Locate the current geographic location of the NFC device through GPS, determine the country code according to the geographic location, and then determine the corresponding NFC configuration file from the corresponding relationship between the country code and the NFC configuration file according to the country code, and call the NFC configuration file. .

In this embodiment, by acquiring the current geographic location information of the NFC device and determining the NFC configuration file corresponding to the current geographic location information, the scanning parameter values of each communication type in the active scanning mode corresponding to the geographic location can be configured accurately, and the scanning parameter values of each communication type in the active scanning mode corresponding to the geographic location can be configured quickly. The corresponding detected object is scanned, which greatly reduces the time of active scanning and saves power consumption. Compared with the short duration, it senses whether there is an NFC-related tag in the surrounding area, and then returns to the normal polling mode. , the active scanning control method of the near-field wireless communication device in this embodiment does not have a delay, which can meet a scenario with high delay requirements and avoid delay overhead.

The sweep parameter value is positively related to the usage scale. The scan parameter value includes at least one of scan duration or scan order. The preset time period can be set as required. For example, from January 1, 2015 to December 31, 2019, the usage ratio of TypeA, Type B, Type F, and Type V for a certain near-field wireless communication device is 0.5:0.4:0.08 and 0.02, you can adjust the scanning parameter value configured by the original ratio of 0.6:0.1:0.02:0.28 according to the new use ratio of 0.5:0.4:0.08 and 0.02 to be more in line with the use of the near-field wireless communication device. user's usage. It can be understood that, according to the usage of each NFC device, the scan duration of a certain type of communication type that is not used can be configured to be 0 or a minimum value.
