[0018] In addition, it should be noted that Figure 1 What is shown is only one system provided by the present disclosure. In practical applications, other systems may also be included, for example, more terminals may be included.

[0019] In the embodiments of this specification, the terminal 10 and the server 20 may be directly or indirectly connected via wired or wireless communication, which is not limited in the present disclosure.

[0020] See next Figure 2 , Figure 2 The overall flow chart of a method for tracking the trajectory of a cigarette workshop staff provided in an embodiment of the present specification is shown. The method for tracking the trajectory of a cigarette workshop staff can be used in the server 20.

[0021] like Figure 2 As shown, the trajectory tracking method of the cigarette workshop staff may at least include the following steps: Step 201: Acquire at least one periodic Bluetooth signal emitted by a Bluetooth beacon in real time.

[0022] Wherein, the Bluetooth beacon is carried by the staff of the cigarette workshop.

[0023] In the embodiments of this specification, in order to determine whether the current operating procedures of the staff in the cigarette workshop are in compliance with regulations and whether they can meet the production requirements, that is, the effectiveness of the production operation, it is necessary to track the trajectory of the staff in the cigarette workshop. When obtaining the movement trajectory of the staff, data can be collected through the Bluetooth positioning method. Therefore, after the staff enters the cigarette workshop, the staff wears or carries a Bluetooth beacon and turns on the working state. In the cigarette workshop, the periodic Bluetooth signal emitted by each Bluetooth beacon can be obtained in real time through a pre-installed Bluetooth receiver or a target terminal with a Bluetooth receiving function. In general, a Bluetooth beacon corresponds to a single staff member, and the Bluetooth signal emitted by the Bluetooth beacon can be obtained by multiple Bluetooth receivers to obtain multiple periodic Bluetooth signals corresponding to a single Bluetooth beacon.

[0024] In one possible implementation, the real-time acquisition of at least one periodic Bluetooth signal emitted by a Bluetooth beacon, wherein the Bluetooth beacon is carried by a cigarette workshop staff, includes: Based on each Bluetooth receiver acquiring in real time a periodic Bluetooth signal sent by at least one Bluetooth beacon, each of the Bluetooth receivers is evenly distributed in the cigarette workshop, and the Bluetooth beacons are carried by the staff of the cigarette workshop.

[0025] In the embodiments of this specification, in order to obtain the Bluetooth signal emitted by the Bluetooth beacon in real time and determine the real-time trajectory of the staff through the difference of the Bluetooth signal obtained by different Bluetooth receivers, multiple Bluetooth receivers can be evenly installed inside the cigarette workshop to ensure that the total receivable range corresponding to all Bluetooth receivers can cover the working area of ​​the entire cigarette workshop, and ensure that there is no significant signal interference between the Bluetooth receivers. Then, the staff carries the Bluetooth beacon to the cigarette workshop, and the Bluetooth beacon remains turned on. The periodic Bluetooth signal sent by the Bluetooth beacon is continuously obtained through the set multiple Bluetooth receivers. Every transmission cycle, the receiving data of all Bluetooth receivers are counted, and a group of periodic Bluetooth signals will be obtained.

[0026] Step 202: Determine the transmission position coordinates corresponding to each of the periodic Bluetooth signals based on a positioning algorithm.

[0027] In the embodiments of the present specification, after multiple periodic Bluetooth signals sent by a Bluetooth beacon are acquired through multiple Bluetooth receivers or target terminals, the signal arrival angles corresponding to the acquired Bluetooth signals with different periodicities can be determined. Then, the received periodic Bluetooth signals are combined with the physical positions between the Bluetooth receivers through a positioning algorithm, and the transmission position coordinates corresponding to the periodic Bluetooth signal are calculated through mathematical modeling.

[0028] Among them, the transmission position coordinates can be determined by positioning algorithms such as the Angle of Arrival (AOA) positioning algorithm, the Time Difference of Arrival (TDOA) positioning algorithm, and the Received Signal Strength Indicator (RSSI) positioning algorithm. Optionally, when the AOA positioning algorithm is used, the transmission position coordinates can be calculated by combining each physical position and each signal arrival angle. When the TDOA positioning algorithm is used, the transmission position coordinates are determined by measuring the time difference of the Bluetooth signal reaching different Bluetooth receivers. When the RSSI positioning algorithm is used, the transmission position coordinates can be determined by the received Bluetooth signal strength.

[0029] In one possible implementation, the determining the transmission position coordinates corresponding to the transmission of each periodic Bluetooth signal based on a positioning algorithm includes: Determine the physical location of each Bluetooth receiver, and determine the signal arrival angle corresponding to each Bluetooth receiver receiving each Bluetooth signal; Based on the Bluetooth AOA positioning algorithm, each of the physical positions and each signal arrival angle is calculated to obtain the transmission position coordinates corresponding to each of the periodic Bluetooth signals.

[0030] In the embodiments of this specification, when the positioning algorithm is used to determine the transmission position coordinates corresponding to each transmission of the group of periodic Bluetooth signals, the physical parameters of each Bluetooth receiver can be determined by measuring and setting the standard coordinate system, and then uploaded to the data record library. Therefore, the physical position of each Bluetooth receiver can be directly determined from the data record library. Then, the signal arrival angle corresponding to each Bluetooth signal when it is received by the Bluetooth receiver is determined by combining the determined physical position of each Bluetooth receiver with the phase difference method. Furthermore, the obtained physical positions and signal arrival angles are mathematically modeled by the Bluetooth AOA positioning algorithm, and the transmission position coordinates corresponding to each periodic Bluetooth signal are determined by geometric relationships.

[0031] As an example, Figure 3 As shown, assume that there are two Bluetooth receivers BS1 and BS2, and the coordinates of Bluetooth receiver BS1 are marked as (x1, y1), the coordinates of Bluetooth receiver BS2 are marked as (x2, y2), the coordinates of the Bluetooth signal transmitting point MS under test are (x, y), and the signal arrival angles of the transmitted Bluetooth signal to Bluetooth receivers BS1 and BS2 are α1 and α2 respectively. Then the equations of the lines where the two transmitting lines are located are y−y1=k1(x−x1) and y−y2=k2(x−x2), where k1=tan(α1) and k2=tan(α2). By combining the following equations, the coordinates of the intersection of the two lines can be obtained.

[0032] The solution to the equation is as follows: In one possible implementation manner, determining the signal arrival angle corresponding to each Bluetooth signal received by each Bluetooth receiver includes: Determine at least one antenna array in each of the Bluetooth receivers, and obtain a receiving phase corresponding to when each of the antenna arrays receives the Bluetooth signal; The receiving phases are calculated based on the phase difference method to obtain the signal arrival angles corresponding to the Bluetooth signals received by each Bluetooth receiver.

[0033] In the embodiments of this specification, after each Bluetooth receiver is installed and set up, the multiple antenna arrays automatically generated by it can be determined accordingly. When the Bluetooth beacon transmits a Bluetooth signal, the antenna array receives the Bluetooth signal and forms a different receiving phase. Then, the determined receiving phases are calculated using the phase difference method to obtain the corresponding signal arrival angle when each Bluetooth receiver receives the Bluetooth signal. The phase difference calculation formula is as follows: α = arcsin(Δϕ / 2πd) Where Δϕ is the phase difference and d is the distance between the antenna arrays.

[0034] Step 203, perform trajectory modeling on the coordinates of each of the launch positions to obtain the real-time trajectory of the cigarette workshop staff, and generate work information of the cigarette workshop staff based on the real-time trajectory and the position of each cigarette process equipment, wherein the work information is used to characterize the effectiveness of the current production operation of the cigarette workshop staff.

[0035] In the embodiment of the present specification, after determining the emission position coordinates corresponding to each periodic Bluetooth signal emitted by the Bluetooth beacon, all emission position coordinates within a fixed time are counted, and the fixed time is set to be greater than the theoretical maximum process operation time. Next, the real-time trajectory of the cigarette workshop staff is determined through trajectory modeling based on each emission position coordinate. Furthermore, the trajectory movement sequence of the cigarette workshop staff between each cigarette process equipment and the length of stay at each cigarette process equipment position are determined by combining the determined real-time trajectory with the equipment position corresponding to each cigarette process equipment, and compared with the preset target process and target time, and the comparison result is used to determine whether the current production operation of the cigarette workshop staff is compliant and effective, and is defined as work information.

[0036] In one possible implementation, the performing trajectory modeling on the coordinates of each of the emission positions to obtain the real-time trajectory of the cigarette workshop staff includes: Constructing the initial trajectory model of cigarette workshop workers based on machine learning algorithms; Based on the time series analysis method, the coordinates of each launch position are input into the initial trajectory model to obtain the real-time trajectory of the cigarette workshop staff.

[0037] In the embodiments of this specification, a large amount of historical test position coordinate data can be obtained first, and pre-processing operations such as data cleaning and normalization can be performed on each coordinate data, and then a neural network model can be selected to train the labeled standard position data to obtain a trained initial trajectory model. Next, the launch time corresponding to each position coordinate obtained in real time is determined based on the time series analysis method, and arranged in chronological order to obtain time series data. Further, the determined time series data is input into the initial trajectory model to obtain and display the real-time trajectory of the cigarette workshop staff.

[0038] In one possible implementation, after performing trajectory modeling on the coordinates of each of the emission positions to obtain the real-time trajectory of the cigarette workshop staff, the method further includes: Determining a matching result between the real-time trajectory and a preset danger zone; The danger warning mode is determined based on the matching result and the warning information is uploaded.

[0039] In the embodiment of this specification, in addition to the normal operable area, there are many dangerous areas in the cigarette workshop during the production process. When the staff enters the dangerous area or stays in the dangerous area, it is very easy to cause a safety accident. Therefore, after determining the real-time trajectory of the staff of the cigarette workshop, the determined real-time trajectory can be matched with the preset dangerous area to obtain a matching result. Among them, when the matching result is 0, it indicates that there is no contact coverage between the determined real-time trajectory and the preset dangerous area. When the matching result is not 0, it indicates that there is contact coverage between the real-time trajectory and the preset dangerous area, and the larger the matching result, the larger the contact coverage rate. Therefore, the dangerous alarm mode can be determined by determining the matching result and uploading the warning information. When the matching result is 0, no warning information is generated and the continuous monitoring state is maintained. When the matching result is not 0, but does not exceed the matching threshold preset by the target terminal, the dangerous alarm model is determined to be the first alarm mode, that is, voice broadcast and upload the warning information. When the matching result exceeds the matching threshold preset by the target terminal, the dangerous alarm mode is determined to be the second alarm mode, and the production of the cigarette workshop process is immediately stopped, and the warning light and voice broadcast are turned on at the same time, and the warning information is uploaded.

[0040] In one possible implementation, the generating of the work information of the cigarette workshop staff based on the real-time trajectory and the location of each cigarette process equipment includes: Determine the working order and stay time of the staff of the cigarette workshop between the locations of the cigarette process settings based on the real-time trajectory and the locations of the equipment of each cigarette process; Comparing the working sequence with the preset process to obtain a first comparison result, and comparing the residence time with the theoretical minimum operation time to obtain a second comparison result; The work information of the cigarette workshop staff is generated based on the first comparison result and the second comparison result.

[0041] In the embodiment of the present specification, the determined real-time trajectory is combined with the position of each cigarette process equipment to determine the work order and residence time of the staff between the various process equipment in the cigarette workshop. Then, the work order is compared with the preset process that meets the standard requirements to obtain a first comparison result, and the residence time is compared with the theoretical minimum operation time that meets the standard requirements to obtain a second comparison result. Further, only when the first comparison result is characterized by the actual work order obtained being the same as the preset process, and the second result is characterized by the residence time being greater than the theoretical minimum operation time, it is judged that the current production operation of the cigarette workshop staff is valid at this time, and the corresponding operation compliance work information is generated. Except for the above situation, the operation non-compliant work information is generated. By collecting the work information of the staff for the supervision and management of the subsequent production process and the production plan arrangement, when the operation non-compliant work information is received, the staff can be automatically prompted to perform a second re-inspection operation to reduce human operation errors and improve production efficiency.
