1. Ultrahigh frequency anti-metal radio frequency identification

The tool box has the main functions of detecting the in-place condition of tools, timely and reliably providing the tool information in the tool box for users, and prompting the users to timely reset the tools to the correct positions in the case of missing or misplacement of the tools in a voice broadcasting and display mode. The radio frequency identification adopts an integrally packaged 915Mhz ultrahigh frequency radio frequency identification module, an R2000 radio frequency identification chip is built in, the chip is the best solution in the current radio frequency identification industry, the chip has the characteristics of high power, strong signal, high identification speed and multi-target accurate identification, an I-Search dynamic Q anti-collision algorithm of version 2.0 is built in, and the algorithm adopts a brand new data model, so that the hardware resource of the chip can be fully utilized, and the difference between the identification efficiency and the identification accuracy of the chip and the traditional algorithm can be obviously felt when the number of labels is large. The main control chip used by the tool box control circuit is STM32F407VGT6 of ST company, the chip has 1024K flash memory space and 192K RAM, and has abundant on-chip peripheral resources, the main frequency 160Mhz and F4 have lower power consumption compared with F1 series, are suitable for mobile electronic products powered by batteries, have stronger floating point operation capability, have higher main frequency, are suitable for rapidly processing a large amount of data, are used as a 32-bit embedded system main control chip, can meet the requirement of high-speed communication with a radio frequency identification module, and can combine a simplified and efficient control resolving program to filter and convert the data returned by the radio frequency module in a short time to obtain effective tool information and convert the effective tool information into display content and voice prompt information on a display screen. The radio frequency identification process is as follows: after the box closing action is detected by a Hall element arranged in the box, radio frequency identification is started within 200ms, and along with voice prompt in detection, all tag information in the tool box is carried out within 2 seconds, two groups of flat antennas are respectively subjected to 3 tag inventory operations, and an anti-collision algorithm is carried out twice for each inventory operation, so that the optimal collocation of the tested recognition efficiency and accuracy is achieved. If the tool is lost, a wheel storing operation is performed, so that the missing reading rate is reduced. In the testing process, the method has the advantages that the repeated values are firstly stored for multiple times, then the repeated values are removed to be cached, and then compared with the method of reading the stored data in real time and then removing the repeated values, the method is higher in efficiency, and the characteristics of the dual-CPU architecture of the radio frequency identification module can be better played, namely, the main CPU is responsible for polling the tags, and the auxiliary CPU is responsible for data management and processing. But this approach presents difficulties in serial port reading because the data time intervals returned by the modules are not uniform. If the STM32 frame interrupt mode is adopted to read the data returned by the serial port, for the program in the first mode, the data uploaded by each frame in real time can be accurately analyzed; however, for the program of the second reading mode, abnormal situations of packet loss and packet sticking occur for many times in the testing process. In order to avoid the situation, a frame interrupt mode is abandoned, a frame of data is read firstly, the length of the subsequent data is determined according to the frame of data, the returned tag information is read in byte units, when all the returned data are judged to be stored in the buffer area, serial port interrupt is triggered, the CPU responds to the interrupt to perform data processing, corresponding tool box number and tool label information are obtained, retrieval and comparison are performed with tool information in the SD card, all the tool information in the tool box is detected at the time, comparison is performed with all the tool information, and tools of missing tools and error-free tool boxes are prompted. While the tool tag information may also include other information over the life of the tool, including date of start-up and responsible person, etc. All tool information is stored in the EPC region of the tag in a coded manner, which can greatly improve the reading efficiency, the time for tool identification is reduced, and the requirements of actual use conditions are met.

2. Fingerprint unlocking, use information recording and inquiring

In order to ensure that only internal personnel can use the tool box, a fingerprint identification unlocking function is added to the tool box. In view of the fact that a large amount of fingerprint information and usage records cannot be stored in the STM32F407VGT6 chip for a long time, stable storage of the fingerprint information is necessary for normal use of the tool box, and recording of the usage information of the tool box is an essential ring in maintenance work of the machine.

On hardware, the ATK-301 capacitive fingerprint identification module has the advantages of low power consumption, high identification speed, high accuracy, small volume and the like, and can meet the use requirement of being installed on a toolbox. The tool box is internally provided with an 8GB SD card for stably storing fingerprint information (50 groups) and usage records (5000 pieces).

In the standby state, the tool box is in a low power consumption mode. Pressing fingerprint sensor under the low-power consumption state, power module can be for bluetooth communication module, fingerprint module, SD card storage module, voice broadcast module and OLED display module power supply, and the toolbox begins normal work.

The tool box is controlled by the WeChat applet to input and delete fingerprints: the low-power consumption state of the toolbox is relieved by pressing the fingerprint module, then the Bluetooth and WeChat applet of the mobile phone are opened, bluetooth link is established with the toolbox, and at the moment, fingerprint input and fingerprint deletion operations can be performed according to the prompt of the WeChat applet. Personnel information input in the fingerprint input process is stored in sectors (0-49) specified by the SD card according to specific codes.

Fingerprint entry

And opening a micro-letter applet, establishing a Bluetooth link with the tool box, opening a fingerprint input interface in the micro-letter applet, clicking a fingerprint input start, and sending a fingerprint recording instruction to the tool box by the micro-letter applet. When the tool box receives a fingerprint recording instruction sent by the WeChat applet through the Bluetooth serial port, the tool box can enter a working state of fingerprint recording. The fingerprint recording process comprises the following eight steps:

and (1) displaying action prompt sentences through a display screen, and waiting for the corresponding position of the finger to press the fingerprint template.

And (2) displaying a fingerprint recording progress bar through a display screen, acquiring a fingerprint image through a fingerprint sensor, and generating fingerprint characteristics.

And (3) synthesizing a fingerprint template according to the fingerprint characteristics generated in the step (2).

And (4) storing the fingerprint template synthesized in the step (3) into an internal storage unit of the fingerprint sensor.

And (5) repeating the steps (2) - (4) five times, wherein the fingerprint recording progress bar is one more lattice after repeating the steps once, and when the fingerprint recording progress bar on the display screen is full, the composition and storage of five fingerprint templates are completed on the position of the finger.

And (6) changing action prompt sentences displayed on a display screen, prompting positions (upper edge of a finger, lower edge of the finger, left side of the finger and right side of the finger) for recording fingerprints, repeating the steps (1) - (5), and respectively synthesizing and storing five fingerprint templates at four positions of one finger.

And (7) inputting personnel information (name, job and ID card number) corresponding to the finger through a WeChat applet.

Step (8), judging whether an instruction for suspending fingerprint input is received in the fingerprint input process, if yes, exiting the fingerprint input process and clearing all information recorded in the fingerprint input process; if not, all information of the currently entered finger is recorded in one sector in the SD card.

(II) fingerprint deletion

And opening a WeChat applet, establishing a Bluetooth link with the toolbox, opening a fingerprint input interface in the WeChat applet, clicking a fingerprint deletion, and sending a fingerprint deletion instruction to the toolbox by the WeChat applet. When the tool box receives a fingerprint deleting instruction sent by the WeChat applet through the Bluetooth serial port, the tool box enters a fingerprint deleting working state. The fingerprint deleting process comprises the following three steps:

and (1) receiving an instruction sent by the WeChat applet through the Bluetooth module.

And (2) reading the data bit of the instruction, and judging the fingerprint deleting mode (deleting specific fingerprint information and deleting all the fingerprint information) according to the data bit.

Step (3), if the deleting mode is to delete specific fingerprint information, searching and clearing corresponding specific fingerprint information (including all relevant information in SD card and fingerprint sensor) according to the information read out by the data bit of the instruction; and if the deleting mode is all deleting, all the recorded fingerprint information in the SD card and all the fingerprint templates generated in the fingerprint sensor are emptied.

(III) fingerprint search

For a toolbox with stored fingerprint information, the electromagnetic lock in the toolbox is opened firstly by brushing the fingerprint when the toolbox is used, and then the toolbox is opened. The "fingerprint search" process automatically generates a usage record for the tool box and stores it in a specific sector of the SD card. The storage of the toolbox usage records adopts a storage mode of a queue, so that the latest 5000 usage records are always reserved in the SD card.

When the tool box is in a normal working state, the fingerprint sensor is pressed by a finger, and the tool box can enter a working state of fingerprint searching (if the tool box is in a low-power-consumption state, the tool box can enter the normal working state from the low-power-consumption state). The fingerprint searching process comprises the following five steps:

and (1) automatically collecting fingerprints through a fingerprint sensor, and searching matched templates in a fingerprint library.

Step (2), if a matched template is searched, returning storage position information corresponding to the template, changing the level of electromagnetic lock control voltage, controlling the telescopic shaft of the electromagnetic lock to retract, and opening the electromagnetic lock; if not, the fingerprint searching process is aborted.

And (3) storing the position information according to the fingerprint template returned in the step (2), and finding out the corresponding personnel information in the SD card.

And (4) encoding the personnel information found in the step (3) and the time information at the moment into a use record according to a specific format.

And (5) storing the usage record generated in the step (4) in a specific sector of the SD card according to a certain format (the latest 5000 usage records are always stored in the SD card).

3. OLED display

In terms of human-computer interaction, we use a 126×64 resolution OLED screen for the display of the toolbox operation panel. The display screen commonly used by the intelligent electronic equipment is LCD, OLED, TFT, and the OLED screen is selected because the contrast is higher, the color is more bright, the using effect is excellent under the outdoor strong illumination condition compared with other display screens of several types, so that the OLED screen is more suitable for the characteristics of the duty work under the outfield condition.

During use of the tool box, when the tool box is in the following working phase, the display will display the following:

standby mode-in standby state, the screen is off screen and does not display content.

Wake mode—when in standby state, after the staff presses the fingerprint identifier, the tool box enters the wake mode, at this time, if the fingerprint is pressed, the tool box will enter the working state, at this time, the screen will display the tool state in the box as shown in fig. 6 (a), wherein the upper right corner displays the electric quantity, the tool number display number will change along with the change of the tool number in the box, at the same time, when the tool in the box is not full, the tool box on the left side of the screen will show the pattern of fig. 6 (b).

If the pressed fingerprint is not entered, the toolbox will enter a time display state in which the display screen will display the current date and time in the center of the screen, while the lower right corner of the screen will display a petaline progress bar as in fig. 7, when the progress bar rotates two turns (i.e. after 3 seconds), the screen will stop, and the toolbox will reenter the standby mode.

Bluetooth mode-if a user wants to enter information and fingerprint, he needs to enter information after the Bluetooth mode is used to connect the tool box with the corresponding mobile phone Bluetooth.

When the tool box is in the Bluetooth mode, the display screen displays the Bluetooth mode as shown in fig. 8, and in the process of Bluetooth connection with the mobile phone, the four small frames at the periphery of the Bluetooth mode display frame in the center of the screen rotate and disappear to represent the connection state of Bluetooth, and after connection is completed, the four small frames appear simultaneously to represent that connection is completed.

Fingerprint input mode-after the Bluetooth connection is finished, a worker can transmit an instruction for inputting the fingerprint to the tool box through a mobile phone. At this point, the tool box enters a fingerprint-entry mode.

After entering the fingerprint-entry mode, the middle of the screen will display an indication as in fig. 9 (a), in turn prompting the operator to perform the finger up (down, left, right) operation along the pressing sensor. While each time the sensor is pressed, the screen will display a progress bar as in fig. 9 (b) to indicate the progress of the fingerprint entry, and when the progress bar is full, the next finger pressing sensor operation can be entered.

When the fingerprints are recorded on the upper, lower, left and right edges of the finger, the screen displays the number of the recorded fingerprints after the fingerprints are recorded, and the screen enters a standby mode after a few seconds.

4. Voice prompt

In order to ensure that the toolbox can bring better human-computer interaction experience to a user, a voice broadcasting function is added to the toolbox. The voice broadcasting modules on the market at present have a lot, comprehensively consider the cost and performance scheduling problem, and this toolbox selects JQ8400 pronunciation chip, and this chip has following advantage: MP3 and WAV hardware decoding is supported, so that the voice prompt is convenient to manufacture, input and play; the combined broadcasting function is supported, and the missing or misplaced tools in the tool box can be subjected to voice prompt in a combined broadcasting mode; the tool box can enter a deep sleep state after entering a low power consumption mode, the current is as low as 600 microamps, and after the tool box main control chip is awakened, the voice module can be awakened to work under the control of instructions, so that the purpose of reducing power consumption is achieved.

In the process of using the toolbox, when the staff executes the operations of resetting the toolbox, opening/closing the toolbox, connecting Bluetooth and the like, the staff has corresponding voice broadcasting prompts:

when the toolbox is powered on or reset and restarted, a prompt 'n-number toolbox initialization success' is reported after the initialization is completed.

When the tool box is opened by a worker, the tool box can report a prompt of welcome use.

After the tool box is closed by a worker, the tool box can automatically search the in-place situation of the internal tool and report a prompt of 'in-process detection', and after the detection of the tool is finished, the tool box can report the in-place situation of the internal tool through voice when transmitting information to an upper computer:

(1) the tools are all reset, and the tool box can report that the tools are all in place.

(2) Tools are not reset in the tool box, and the tool box can detect which tool or tools are not reset and report XX (tools) and XX (tools) missing.

(3) Tools which do not belong to the tool box are misplaced in the tool box, and the tool box can detect which tool or tools are misplaced and broadcast XX (tool) and XX (tool) misplaced tool box.

When the tool box is connected with the Bluetooth of the upper computer, the tool box can broadcast a prompt that Bluetooth is connected and enter a Bluetooth mode, and at the moment, fingerprint input, tool inquiry and other operations can be performed through the mobile phone applet control tool box.

When the tool box is disconnected with the Bluetooth of the upper computer, the tool box can report a prompt that the Bluetooth is disconnected and exits from the Bluetooth mode, and the system enters into the low-power consumption mode after waiting for a short time.

5. Bluetooth communication

The wireless Bluetooth version of the IOneBox intelligent tool box realizes data transmission between the tool box and the mobile terminal through Bluetooth wireless communication. Since the WeChat applet used by the mobile only supports BLE4.0 and above communication protocols, we use the Bluetooth module HC-08 supporting BLE4.0 protocol. The Bluetooth module is in a low-power consumption state when not connected so as to save the use of the electric quantity of the tool box; the HC-08 module can replace physical connection in full duplex communication in a connection state, and can realize 80 m ultra-long distance communication in an open environment.

To solve the problem that BLE4.0 communication protocol cannot exceed 20 bytes per frame data when data transmission is performed, we define a bluetooth packet protocol suitable for the toolbox: each piece of transmission data is divided into a header end (used for determining whether the transmission data is a valid data packet or not), a data length (the byte length of the whole data packet), a command (a specific operation command can support 256 different command instructions at most), a data packet (the transmission data content can send data packets with more than 20 bytes) and a checksum (checking whether the transmission data has errors). The data transmission is carried out through the data packet protocol, so that the instruction operation and the data content to be carried out can be simply extracted, and whether the transmission data has errors or not can be checked.

The wireless Bluetooth version of the IOneBox intelligent tool box is matched with a WeChat applet to provide mobile terminal software helper service, the OITB cloud helper is searched in the mobile phone WeChat applet, and the mobile phone WeChat applet can be used after entering. The functions supported by the WeChat applet are as follows:

carry out bluetooth with the toolbox and connect:

bluetooth connection with the tool box can be performed at the bluetooth interface of the OITB cloud assistant. The WeChat applet supports the BLE4.0 communication protocol, and the software assistant uses the API related to peripheral equipment, bluetooth and low-power consumption Bluetooth of the WeChat applet to communicate with the HC-08 Bluetooth module on the toolbox, and can realize data mutual transmission after successful connection.

Checking the in-place condition of tools in the tool box:

the user can check in real time whether each tool in the tool box is in place or not on the tool box interface of the OITB cloud assistant. If the tool is lost, the picture of the tool can be displayed by clicking the name of the tool, so that a user can find the tool conveniently. In addition, tools not belonging to the tool box may also be displayed in the mobile software assistant.

Fingerprint input and deletion of a user:

the user can perform fingerprint input and deletion on the fingerprint input interface of the OITB cloud assistant. After clicking the key for starting fingerprint input and pressing the step of toolbox prompt to finish fingerprint acquisition, the user also needs to input names, identification numbers and job titles on the software aid in sequence, and after all the information is input, the fingerprint input process is finished. After clicking the "delete fingerprint" button, the name and ID card number of the owner of the fingerprint to be deleted are input on the software assistant to delete the fingerprint, and in addition, the specific instruction can be input to clean all the fingerprints.

(4) Synchronizing time and viewing usage records

The user can synchronize the time on the tool box and view the tool box usage record on the use interface of the OITB cloud assistant. The software assistant can acquire the Internet time in real time, and can click a 'synchronous time' button to manually synchronize the time of the toolbox in order to prevent the time on the toolbox from generating deviation. After the page selects the month for which a query is desired, the name and time of use (specifically to minutes) of the user using the toolbox during the month may be displayed.

The OITB cloud assistant is matched with the wireless Bluetooth version of the IOneBox intelligent tool kit, and obtains corresponding services through Bluetooth connection with the tool kit.
