[0058] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0059] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0060] The technical principles of the wireless card, data analysis method / system, readable storage medium and server provided by the present invention are as follows:

[0061] The wireless card based on wifi technology uses the wifi 801.11g / b protocol and uses data frames to define the card's mac address, transmission channel, voltage conditions, out of monitoring range, etc. during communication data transmission. It uses wifi radio frequency to transmit wireless signals and transmit them to AP, so that AP receives the data and uploads it to the positioning server for analysis, thereby realizing the positioning function.

[0062] Among them, wifi wireless technologies are as follows:

[0063] WiFi uses the IEEE802.11 protocol suite, which includes many sub-protocols. Among them, in chronological order, they are: (1) 802.11a, (2) 802.11b, (3) 802.11g, and (4) 802.11n. In network communication, data is encapsulated into frames, and a frame refers to a data block in communication. However, frames have a fixed format when transmitted at the data link layer. They cannot be transmitted by random encapsulation and packaging. The size is limited, with a minimum of 46 bytes and a maximum of 1500 bytes. Therefore, the wireless card provided by the present invention encapsulates data frames according to this rule.

[0064] Embodiment 1

[0065] This embodiment provides a wireless card, which is attached to the asset equipment to be monitored; the wireless card includes:

[0066] A contact sensing module, used for sensing and sending data signals of the force acting thereon;

[0067] a data processing module, electrically connected to the contact sensing module, for receiving the force data signal, and forming a data frame for transmission according to the force data signal; the frame structure of the data frame includes a first address filled with a broadcast address, a second address filled with a MAC address of the wireless card, and a third address filled with real-time status information of the wireless card;

[0068] The signal transmitting module is electrically connected to the data processing module and is used to transmit the data frame formed by the data processing module.

[0069] The wireless card provided in this embodiment will be described in detail below with reference to the diagram. Figure 1 , which is a schematic diagram showing the principle structure of a wireless card in one embodiment. Figure 1 As shown, the wireless card 1 includes: a contact sensing module 11 , a data processing module 12 , a signal transmitting module 13 , a power supply module 14 , a charging port 15 and a display module 16 .

[0070] The contact sensing module 11 is used to sense and send data signals of the force acting on it. Figure 2 , which is a schematic diagram of the principle structure of the contact sensing module. Figure 2 As shown, the contact sensing module 11 includes a sensor 111 , a connecting member 112 , a force value calculator 113 and an electrical signal converter 114 .

[0071] The sensor 111 protruding from the plane of the wireless card is used to sense the action occurring on the wireless card. The action includes removal or peeling. In this embodiment, the sensor 111 protrudes 2mm from the plane. The connecting piece is a spring. When the sensing occurs when the wireless card is removed or peeled off from the asset device, the spring is in an extended state, which indicates that the asset device is in a dangerous state; when the action occurring on the wireless card is not sensed, the spring is in a compressed state, which indicates that the asset device is in a safe state.

[0072] The force calculator 113 connected to the sensor 111 via a compressible and stretchable connecting member 112 is used to record the force of the connecting member when the sensor senses the action and the connecting member is in an extended state.

[0073] The electrical signal converter 114 electrically connected to the force value calculator 113 is used to convert the applied force into a force data signal, and make a judgment based on a preset force value threshold. If the preset force value threshold is exceeded, the status information of whether the wireless card is removed is marked as wireless card removal status information, and the wireless card removal status information and the wireless card removal alarm information are written into the data frame defined by the data processing module, specifically, written into the third address of the data frame.

[0074] The data processing module 12 electrically connected to the contact sensing module 11 is used to receive the force data signal and form a data frame for transmission according to the force data signal. In this embodiment, the data frame for transmission also needs to be converted into binary data and transmitted in byte mode. In this embodiment, the data processing module 12 can be a microprocessor.

[0075] See also Figure 3 , showing a schematic diagram of the principle structure of the data frame defined by the data processing module. The frame structure of the data frame follows the standard format defined by 802.11g / b, such as Figure 3 As shown, the frame structure 3 of the data frame includes a frame control (Frame Control) 31, a duration (Duration ID) 32, a first address (Address1) 33 filled with a broadcast address, a second address (Address2) 34 filled with a MAC address of the wireless card, a third address (Address3) 35 filled with real-time status information of the wireless card, a sequence control field (Sequence Control) 36, a data segment (Data) 37, and a frame check sequence (FCS) 38. In this embodiment, the real-time status information of the wireless card includes information for indicating the transmission channel identification information of the wireless card, the battery status information of the wireless card, the status information of whether the wireless card is removed, and the removal alarm information of the wireless card.

[0076] For example, the broadcast address defined in the first address (Address1) is: 01-80-80-A2-A2-A2, and the wireless access point devices within the broadcast address range are limited to receive the data frames transmitted by the data processing module. If the wireless access point device is not within the broadcast address range, the data frame will not be received.

[0077] For example, the label MAC address defined in the second address (Address2) is 60-01-94-7e-ea-2f. Each label MAC address is unique and matches each asset device to be used to find the asset device).

[0078] For example, the first 4 bits of the third address (Address3) are the channel (for example, if the channel is 5, the first 4 bits of address3 are 0101; if the channel is 1, the first 4 bits of address3 are 0001)

[0079] The first 2 bits of the second byte of the third address (Address3) are low power and removed flags, respectively, indicating that the voltage of the wireless card is low power and has been removed. In this case, the second byte of Address3 is 11000000. If the second byte of Address3 is 00000000, it indicates that the voltage of the wireless card is not low power and has not been removed.

[0080] In this embodiment, the data format of the complete third address (Address3) is shown in Table 1 in binary format, and its length is 6 bytes, each byte is 8 bits. If there is a specific business expansion requirement, data can be defined in the reserved position of the reserved field.

[0081] Table 1: Example of the data format of the third address (Address3)

[0082] Channel ID Card removal alarm Reserved Fields Reserved Fields Reserved Fields Reserved Fields 00010000 11000000 00000000 00000000 00000000 00000000

[0083] The signal transmitting module 13 electrically connected to the data processing module 12 is used to transmit the data frame formed by the data processing module. In this embodiment, the signal transmitting module 13 transmits wireless signals according to the 802.11g / b protocol standard. The signal transmitting module 13 transmits information in turn according to channels 1 to 13 of 802.11g / b, and it will be marked in the data of the transmitting frequency channel. For example, the signal is first transmitted on channel 1, and the first 4 bits of Address3 can be identified at this time; then the signal is transmitted on channel 2 again after a few seconds, which is similar to cyclic transmission.

[0084] The power supply module 14 is electrically connected to the data processing module 12 and the signal transmission module 13 and is used to supply power to the wireless card 1. When the operating voltage of the power supply module is lower than the voltage warning value, the power supply module 14 reports to the data processing module 12 so that the data processing module 12 writes the operating voltage lower than the voltage warning value into the battery status information of the wireless card at the third address Address3. In this embodiment, in order to charge the power supply module, a charging port 15 is also provided on the wireless card 1, for example, a USB2.0 interface.

[0085] The display module 16 electrically connected to the signal transmission module 13 and / or the power supply module 14 includes a working signal light 161 and a radio frequency signal light 162 .

[0086] The working signal light 161 is electrically connected to the power supply module 13. When the wireless card 1 is powered on, the working signal light 161 is on.

[0087] The RF signal light 162 is electrically connected to the signal transmitting module 13 and the power supply module 14. When the signal transmitting module 13 transmits a data frame, the RF signal light 162 is displayed.

[0088] The wireless card described in this embodiment defines the data format to be sent, transmits wireless signals through the WiFi radio frequency module, and follows the WiFi 802.11g / b protocol to ensure that the data can be transmitted in a wireless environment and acquired by the wireless device, so as to achieve support for wireless devices from multiple manufacturers; and the wireless card has the function of an alarm signal: that is, when the battery of the wireless card is insufficient, a battery alarm signal will be sent and the administrator will be informed; when the wireless card is separated from the asset equipment or when the wireless card exceeds a certain area of ​​AP signal strength, a removal alarm signal will be sent and the administrator will be informed, so as to facilitate the administrator's daily maintenance and management.

The wireless card is used to form a data frame in a standard format defined by 802.11g / b, and transmit the data frame to a wireless access point defined within its broadcast address range.

[0091] The frame structure of the data frame includes a frame control (Frame Control), a duration (DurationID), a first address (Address1) filled with a broadcast address, a second address (Address2) filled with a MAC address of the wireless card, a third address (Address3) filled with real-time status information of the wireless card, a sequence control field (Sequence Control) and a data segment (Data).
