Description

Technical Field

[0001] This invention relates to the field of mobile terminal technology, specifically to an anti-interference mobile terminal for on-site safety management. Background Technology

[0002] The on-site safety management mobile terminal mainly uploads on-site video data to the back-end management system in real time, generates corresponding data reports, and enables unified scheduling, which greatly improves work efficiency, timely predicts misoperations, and avoids safety accidents.

[0003] Existing mobile control terminals cannot classify data during data transmission, leading to bandwidth congestion and low transmission efficiency when the amount of collected data is large. Furthermore, the lack of signal or low transmission rate at the construction site can interfere with data transmission. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing mobile terminals being unable to transmit data reasonably, easily causing bandwidth congestion, low transmission efficiency, and interference with data transmission due to the lack of signal at the construction site, and to propose an anti-interference mobile terminal for on-site safety management.

[0005] The objective of this invention can be achieved through the following technical solution: an anti-interference mobile terminal for on-site safety management, comprising a mobile terminal body, wherein the mobile terminal body is internally provided with a data acquisition module, a data identification module, a real-time transmission module, a data storage module and a data analysis module;

[0006] The data acquisition module is used to collect equipment information and site information at the construction site and send them to the data recognition module;

[0007] The data recognition module is used to identify and classify equipment information and field information to obtain corresponding first and second collected information, and sends the first collected information to the real-time transmission module and the second collected information to the data storage module for storage.

[0008] The real-time transmission module receives the first collected information and sends it to the backend server;

[0009] The data analysis module is used to perform storage volume statistics and analysis on the second collected information. The specific analysis process is as follows:

[0010] When the storage amount of the second collected information is equal to or greater than the set storage threshold, the second collected information is encrypted and compressed to obtain an encrypted compressed package.

[0011] Send a transmission request command to the registration end to obtain a confirmation signal from the registration end, and mark the registration end that sends the confirmation command as the request originator; parse the confirmation signal to obtain the confirmation information of the request originator, which includes the model, location and remaining memory; process the confirmation information to obtain the request value of the request originator, and mark the request originator with the largest request value as the relay end;

[0012] Send a transmission confirmation message to the relay terminal. After receiving the transmission confirmation message, the personnel at the relay terminal will bring the relay terminal to the location of the mobile terminal and connect the relay terminal to the data analysis module via Bluetooth or data cable.

[0013] The encrypted compressed package is sent to the relay terminal via Bluetooth or data cable. After receiving the encrypted compressed package, the relay terminal arrives at the corresponding location and sends the encrypted compressed package to the backend server.

[0014] In a preferred embodiment of the present invention, the specific process of processing the confirmation information is as follows:

[0015] The distance between the location of the requesting terminal and the location of the mobile terminal is calculated to obtain the mobile terminal spacing TG1. Then, the model of the requesting terminal is matched with several preset models stored in the data storage module, where each preset model corresponds to a preset fixed value. When a matching preset model is found, the preset fixed value of that preset model is marked as the initial terminal base value of the requesting terminal. An upload rate acquisition signal is sent to the requesting terminal to obtain the average upload rate of the requesting terminal. The initial terminal base value, the average upload rate, and the remaining memory are normalized, and the normalized values ​​are marked as D1, D2, and D3, respectively. The weight coefficients for the initial terminal base value, the average upload rate, and the remaining memory are set as fs1, fs2, and fs3, respectively, and substituted into the formula... Get the hard base value TG2 of the request origin; get the end-transmitted value TG3 of the request origin. When the request origin is the initial registration, the end-transmitted value is directly taken as ten.

[0016] Draw circles with the base value and end-transfer value as radii, align the centers of the two circles on the same horizontal line, and make the two circles tangent to each other. Select the point of tangency between the two circles, and draw a spacing line segment perpendicular to the horizontal line starting from this point of tangency. The length of the spacing line segment is equal to the value distance ratio obtained by dividing the preset value by the end-transfer distance. Draw tangents to the two circles from the end points of the spacing line segments to obtain point tangents. Calculate the area of ​​the closed region constructed by the point tangents and the two circles, extract the area value, and mark it as the input value.

[0017] In a preferred embodiment of the present invention, the data analysis module further includes an information acquisition unit. This unit acquires the time at which the relay receives the encrypted compressed package (time 1) and the time at which the backend server receives the encrypted compressed package (time 2). It then performs time difference analysis on time 1 and time 2 to obtain the single transmission duration of the relay. The single transmission duration is labeled as Tj, where j = 1, 2, ..., n, and n is the total number of single transmission durations. Finally, the single transmission duration values ​​are chronologically input into a line graph, and points corresponding to adjacent single transmission duration values ​​are connected to obtain the transmission timeline. Calculate the slope of the transmission line and its angle with the horizontal line. When the angle between the transmission line and the horizontal line is greater than 90 degrees, the slope of the transmission line is marked as the first slope. When the slope of the transmission line is less than 90 degrees, it is marked as the second slope. Summate the absolute values ​​of all the first slope values ​​to obtain the total first slope. Sum the values ​​of the second slope values ​​to obtain the total second slope. Divide the total first slope by the total second slope to obtain the time slope ratio and mark it as Sg. Use the formula TG3=Sg×fs4+n×fs5+10 to obtain the end-transmission value TG3 of the relay end. Where fs4 and fs5 are weighting coefficients.

[0018] In a preferred embodiment of the present invention, the real-time transmission module further includes a rate detection unit. The rate detection unit is used to detect the upload rate of the real-time transmission module. When the upload rate is less than or equal to a preset rate threshold, the received first collection information is encrypted and compressed to obtain an encrypted compressed package and sent to the data analysis module.

[0019] In a preferred embodiment of the present invention, the mobile terminal body is further provided with a data registration module. The data registration module is used for on-site security personnel to submit personnel information for registration through the smart terminal and send the successfully registered personnel information to the data storage module. At the same time, the smart terminal that has successfully registered is marked as the registration terminal. The personnel information includes the security personnel's name, length of employment, communication number, etc.

[0020] In a preferred embodiment of the present invention, the mobile terminal body is installed inside the outer casing. A set of brackets is installed on each of the six outer side walls of the mobile terminal body. Each bracket consists of two shaft mounting brackets symmetrically installed at the edge of the outer side wall. An intermediate shaft is installed on the two shaft mounting brackets, and multiple support rods are installed on the intermediate shaft. A motor is installed on one of the shaft mounting brackets, and the output shaft of the motor is connected to one end of the intermediate shaft through a coupling. Two springs are symmetrically installed on both sides of the shaft mounting bracket, and the two ends of the springs are fixedly connected to the outer side wall of the mobile terminal body and the inner wall of the outer casing, respectively.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention identifies and classifies equipment information and field information through a data identification module to obtain corresponding information. Then, a portion of the collected information is transmitted to the back-end server through a real-time transmission module, thereby achieving real-time transmission of important data and avoiding transmission of it along with some less important data, which would cause bandwidth congestion and low transmission efficiency.

[0023] 2. This invention uses a data analysis module to statistically analyze the storage volume of the second collected information. When the storage volume of the second collected information is equal to or greater than a set storage threshold, the second collected information is encrypted and compressed to obtain an encrypted compressed package. Then, the confirmation information of the corresponding request terminal is obtained, processed to obtain the corresponding input value, and the corresponding relay terminal is obtained through the input value. Then, the collected data is transmitted to the backend server through the relay terminal. On the one hand, this reduces the real-time transmission pressure. On the other hand, when there is no signal in the on-site construction environment, the data is sent to a place with good signal through the relay terminal and transmitted to the backend server through wireless network or bandwidth, avoiding the problem of mobile terminals being unable to transmit data.

[0024] 3. The present invention detects the upload rate of the real-time transmission module through the rate detection unit. When the upload rate is less than or equal to the preset rate threshold, the received first collection information is encrypted and compressed to obtain an encrypted compressed package and sent to the data analysis module. The upload rate is detected by the rate detection unit to facilitate reasonable data transmission and avoid interference with data transmission caused by no signal or low transmission rate at the construction site.

[0025] 4. The pressure detection module of this invention is used for the pressure data of the outer shell. When the pressure data is greater than the set threshold, the motor is controlled to drive the intermediate shaft to rotate, which in turn drives the support rod to rotate, so that the support rod is parallel to the corresponding outer wall. Thus, the outer shell and the mobile terminal body are supported by the spring, and the pressure of the outer shell is absorbed by the spring to prevent the pressure on the outer shell from being transmitted to the mobile terminal body and causing damage to its internal modules.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 As shown, an anti-interference mobile terminal for on-site safety management includes a shell 2, a mobile terminal body 1 installed inside the shell 2, and a backend server that is communicatively connected to the mobile terminal body 1.

[0033] Please see Figure 2 As shown, a set of brackets is installed on each of the six outer side walls of the mobile terminal body 1. Each bracket consists of two shaft mounting brackets 21 symmetrically installed at the edge of the outer side wall. An intermediate shaft is installed on the two shaft mounting brackets 21, and multiple support rods 22 are installed on the intermediate shaft. A motor 23 is installed on one of the shaft mounting brackets 21, and the output shaft of the motor 23 is connected to one end of the intermediate shaft through a coupling. Two springs 24 are symmetrically installed on both sides of the shaft mounting bracket 21, and the two ends of the springs 24 are fixedly connected to the outer side wall of the mobile terminal body 1 and the inner wall of the outer shell 2, respectively.

[0034] The mobile terminal body 1 is internally equipped with a data registration module, a data acquisition module, a data recognition module, a real-time transmission module, a data storage module, a data analysis module, and a stress detection module;

[0035] On-site safety personnel submit their information to the data registration module via a smart terminal for registration. The information of successfully registered personnel is sent to the data storage module for storage, and the smart terminal that has successfully registered is marked as the registration terminal. The personnel information includes the safety personnel's name, length of employment, and contact number.

[0036] The data acquisition module collects equipment and site information from the construction site and sends it to the data recognition module. The equipment information includes the operating parameters and monitoring data of the equipment at the construction site. The site information includes videos captured by on-site cameras.

[0037] The data recognition module identifies and classifies equipment information and field information, classifying information that needs to be uploaded in real time into first-collection information and information that does not need to be transmitted in real time into second-collection information; the first-collection information is sent to the real-time transmission module and the second-collection information is sent to the data storage module for storage;

[0038] The real-time transmission module receives the first collected information and sends it to the backend server. The real-time transmission module is equipped with a rate detection unit, which detects the upload rate of the real-time transmission module. When the upload rate is less than or equal to a preset rate threshold, the received first collected information is encrypted and compressed to obtain an encrypted compressed package and sent to the data analysis module. The upload rate is detected by the rate detection unit to facilitate reasonable data transmission and avoid interference with data transmission caused by no signal or low transmission rate at the construction site.

[0039] The data analysis module performs storage volume statistics and analysis on the second collected information. When the storage volume of the second collected information is equal to or greater than the set storage threshold, the second collected information is encrypted and compressed to obtain an encrypted compressed package.

[0040] A transmission request command is sent to the registration terminal to obtain a confirmation signal from the registration terminal, and the registration terminal that sends the confirmation command is marked as the request initiator. The confirmation signal is parsed to obtain the confirmation information of the request initiator, which includes the model, location, and remaining memory. The confirmation information is processed to obtain the request value of the request initiator. Specifically, the distance between the location of the request initiator and the location of the mobile terminal body 1 is calculated to obtain the mobile terminal distance TG1, and the model of the request initiator is matched with several preset models stored in the data storage module. Each preset model corresponds to a preset fixed value; when a matching preset model is found, the preset fixed value of that preset model is marked as the initial base value of the requesting end; an upload rate acquisition signal is sent to the requesting end to obtain the average upload rate of the requesting end; the initial base value, the average upload rate, and the remaining memory are normalized, and the normalized values ​​are taken and marked as D1, D2, and D3 respectively; the weighting coefficients of the initial base value, the average upload rate, and the remaining memory are set as fs1, fs2, and fs3, and substituted into the formula. Get the hard base value TG2 of the requesting end; get the end-transmitted value TG3 of the requesting end. When the requesting end is the initial registration, the end-transmitted value is directly taken as ten; the values ​​of fs1, fs2 and fs3 can be 0.28, 0.33 and 0.47 respectively.

[0041] Please see Figure 3 As shown, draw circles with the base value and the endpoint value as radii, and make the centers of the two circles on the same horizontal line. At the same time, make the two circles tangent to each other, select the point of tangency of the two circles, and draw a spacing line segment perpendicular to the horizontal line with the point of tangency as the starting point. The length of the spacing line segment is equal to the value distance ratio obtained by dividing the preset value by the endpoint spacing. Draw tangents to the two circles with the end points of the spacing line segment to obtain point tangents. Calculate the area of ​​the closed region constructed by the point tangent and the two circles, extract the area value and mark it as the input value. Mark the request endpoint with the largest input value as the relay endpoint.

[0042] Send a transmission confirmation message to the relay terminal. After receiving the transmission confirmation message, the personnel at the relay terminal will bring the relay terminal to the location of the mobile terminal body 1 and connect the relay terminal to the data analysis module via Bluetooth or data cable.

[0043] The encrypted compressed package is sent to the relay terminal via Bluetooth or data cable. After receiving the encrypted compressed package, the relay terminal arrives at the corresponding location and sends the encrypted compressed package to the backend server.

[0044] The data analysis module also includes an information collection unit;

[0045] Please see Figure 4 As shown, the information acquisition unit collects the time when the relay end receives the encrypted compressed package (time 1) and the time when the backend server receives the encrypted compressed package (time 2). Time difference analysis is performed between time 1 and time 2 to obtain the single transmission duration of the relay end. The value of the single transmission duration is marked as Tj, j=1,2,...,n; n is the total number of single transmission durations. Then, the values ​​of the single transmission durations are substituted into a line graph according to the chronological order, and the points corresponding to two adjacent single transmission duration values ​​are connected to obtain the transmission time line. The slope of the transmission time line and its angle with the horizontal line are calculated. When the transmission time line and the horizontal line... When the angle is greater than 90 degrees, the slope of the transmission line is marked as the first slope. When the slope of the transmission line is less than 90 degrees, it is marked as the second slope. The absolute values ​​of all the first slope values ​​are summed to obtain the total first slope. The values ​​of the second slope values ​​are summed to obtain the total second slope. The total first slope is divided by the total second slope to obtain the time slope ratio and marked as Sg. The end-transmission value TG3 of the relay end is obtained using the formula TG3=Sg×fs4+n×fs5+10. Where fs4 and fs5 are weighting coefficients. The values ​​of fs4 and fs5 can be 0.75 and 0.64, respectively.

[0046] The pressure detection module is used to collect pressure data of the outer shell 2. When the pressure data is greater than the set threshold, the motor 23 is controlled to drive the intermediate shaft to rotate, which in turn drives the support rod 22 to rotate, making the support rod 22 parallel to the corresponding outer wall. This allows the outer shell and the mobile terminal body 1 to be supported by the spring 24. The spring 24 also absorbs the pressure of the outer shell 2, preventing the pressure on the outer shell 2 from being transmitted to the mobile terminal body 1 and causing damage to its internal modules.

[0047] The above formulas are all derived from software simulation using a large amount of data, and are selected to be close to the true values. The coefficients in the formulas are set by those skilled in the art based on the actual situation.

[0048] In use, this invention uses a data identification module to identify and classify equipment and site information to obtain corresponding information. Then, a portion of the collected information is transmitted to the backend server via a real-time transmission module, thus achieving real-time transmission of important data and preventing it from being transmitted along with less important data, which would cause bandwidth congestion and low transmission efficiency. A data analysis module performs storage volume statistics and analysis on the second set of collected information. When the storage volume of the second set of collected information is equal to or greater than a set storage threshold, the second set of collected information is encrypted and compressed to obtain an encrypted compressed package. Then, the confirmation information from the corresponding request endpoint is obtained, processed to obtain the corresponding request value, and used to obtain the corresponding relay endpoint. The relay endpoint then transmits the collected data to the backend server, reducing real-time transmission pressure. Furthermore, in situations where there is no signal at the construction site, the relay endpoint can send the data to a location with good signal via Wi-Fi or other means. Data is transmitted to the backend server via a wide-area transmission method to avoid data transmission problems on the mobile terminal. The upload rate of the real-time transmission module is detected by the rate detection unit. When the upload rate is less than or equal to the preset rate threshold, the received first collection information is encrypted and compressed to obtain an encrypted compressed package and sent to the data analysis module. The upload rate is detected by the rate detection unit to ensure reasonable data transmission and avoid interference with data transmission caused by no signal or low transmission rate at the construction site. The pressure detection module is used to collect pressure data of the outer shell 2. When the pressure data is greater than the set threshold, the motor 23 is controlled to drive the intermediate shaft to rotate, which in turn drives the support rod 22 to rotate, making the support rod 22 parallel to the corresponding outer wall. This allows the outer shell and the mobile terminal body 1 to be supported by the spring 24. The spring 24 also absorbs the pressure of the outer shell 2, preventing the pressure on the outer shell 2 from being transmitted into the mobile terminal body 1 and causing damage to its internal modules.
