[0030]The online inspection system according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0031]The online inspection system according to the embodiment of the present invention includes an informationized miner's lamp and a mobile terminal.
[0032]Specifically, according to the online inspection system of the embodiment of the present invention, the informationized miner’s lamp includes a positioning component and a Bluetooth component. The informationized miner’s lamp establishes a Bluetooth communication connection with the mobile terminal through the Bluetooth component, so that the positioning component connects and moves according to the Bluetooth communication connection. The terminal performs data exchange.
[0033]In other words, the online inspection system according to the embodiment of the present invention is mainly composed of an informationized miner’s lamp and a mobile terminal. The informationized miner’s lamp has a positioning component and a Bluetooth component. The Bluetooth in the informationized miner’s lamp can be connected to the Bluetooth of the mobile terminal. The positioning component It can locate the wearer of the informationized miner's lamp and transmit the position information to the mobile terminal through the Bluetooth component. Specifically, the Bluetooth connection status is indicated to the master control of the positioning component through high and low levels. The Bluetooth is not connected and the positioning component is working in its original function. When Bluetooth is connected, the positioning component sends and receives functional data through the serial port to realize data interaction with the mobile terminal. The Bluetooth component has the characteristics of small size, low power consumption, low cost, two-way transmission, and no data packet loss. Putting the Bluetooth component into the informationized miner's lamp will not affect the original functions of the informationized miner's lamp. Bluetooth components are mainly composed of Bluetooth chips, buttons, LED indicators, serial ports and antennas, among which the Bluetooth chip is based on 64MHz, 32-bit The core low-power Bluetooth system-level SOC chip nRF52810QCAA. Such asfigure 1 Shown is the schematic diagram of the Bluetooth components.
[0034]The mobile terminal may be a smart device such as a smart phone or a mobile phone for miners. The mobile terminal is equipped with app software that matches the informationized miner's lamp. Underground workers can locate themselves according to the positioning components in the informationized miner’s lamp, and can also identify dangerous areas, and transfer relevant information to the mobile terminal app software via Bluetooth, which is not only convenient for underground workers to check at any time, but also to know themselves in time The location, with the app software, can perform operations such as diagnosis, inspection, number change, and alarming of the informationized miner’s lamp at any place in the coal mine. Specifically, the diagnosis methods of the informationized miner's lamp include user self-diagnosis and black box data diagnosis. Among them, using a diagnostic function on the app software, through text and image prompts, guide users of informationized miner's lamp step by step to test miner's lamp lighting, power, distance measurement and other functions to realize the user's self-diagnosis. On the other hand, the mobile terminal app software can easily read the running records of the miner's lamp positioning component, and realize the black box function.
[0035]Furthermore, mobile management can be realized. Under normal circumstances, the informationized miner’s lamp positioning component works in tag mode, and communicates with the underground positioning base station for distance measurement. Through the mobile terminal app, the informationized miner’s lamp positioning component can be switched to the base station mode and act as a mobile positioning base station. Realize management operations such as patrol inspection, number change, and alarm sending for other information miner's lamps around. It can not only diagnose the faults of the informationized miner's lamp in time, but also greatly facilitate the management personnel to carry out mobile management of the positioning card, and reduce the equipment cost.
[0036]Therefore, according to the online inspection system of the embodiment of the present invention, the data interaction between the positioning component in the informationized miner's lamp and the mobile terminal is realized through the Bluetooth communication connection. On the one hand, the online inspection system realizes human-computer interaction and provides data support for the location of the underground personnel. On the other hand, it enables the informationized miner's lamp to have a mobile base station mode, which can identify the fault of the informationized miner's lamp. The online inspection system has the advantages of low cost, low power consumption, good scalability, no impact on the original functions and performance of the informationized miner's lamp, and easy use.
[0037]According to an embodiment of the present invention, the Bluetooth component controls the Bluetooth component to be in different modes according to the connection state and communication condition between the Bluetooth component and the mobile terminal. The modes of the Bluetooth component include sleep mode, broadcast mode and transparent transmission mode. In other words, the Bluetooth communication component can be operated in different working modes according to the connection status and communication conditions between the mobile terminal and the Bluetooth communication component. Without affecting the normal use of the original functions of the information miner's lamp, the information miner's lamp has diversified functions and human-computer interaction to meet the needs of multiple application scenarios.
[0038]Such asfigure 2 As shown, further, the sleep mode, the broadcast mode and the transparent transmission mode can be switched mutually. Among them, the sleep mode can make the Bluetooth component in the lowest power consumption mode, so that the core of the Bluetooth component and all running tasks are stopped, only Wake up in response to the GPIO level of the button. Specifically, the current in the sleep mode is less than 1uA, the power consumption is extremely small, and it does not cause any impact on the lighting time of the information miner's lamp. When the button level change is detected in the sleep mode, the Bluetooth component will exit the sleep mode and enter the broadcast mode.
[0039]The broadcast mode can make the Bluetooth component work in the slave mode, and send a broadcast packet to wait for the Bluetooth connection with the mobile terminal, and after the connection is successful, the Bluetooth component enters the transparent transmission mode. In the broadcast mode, the broadcast interval is 100ms, the broadcast timeout is 300s, the average working current is about 1mA, the working time is short, and the power consumption of one broadcast cycle will not affect the lighting time of the information miner's lamp.
[0040]The transparent transmission mode enables the Bluetooth component to notify the positioning component of the current Bluetooth connection status through the control level change, so that the positioning component works in a data interaction mode with the mobile terminal. Specifically, the Bluetooth component notifies the positioning component through the level change of IO to change the connection state of the Bluetooth. In the transparent transmission mode, the Bluetooth component uses the transparent transmission principle to transmit the communication data between the positioning component and the mobile terminal. When the mobile phone is actively disconnected or the Bluetooth component detects that there is no Bluetooth data communication for a long time, the Bluetooth connection is disconnected, the transparent transmission mode is exited, and the broadcast mode is entered. The average working current of the Bluetooth component in the transparent transmission mode is about 10mA.
[0041]In some specific embodiments of the present invention, when the Bluetooth component in the sleep mode detects a key level change, it will exit the sleep mode and enter the broadcast mode; when the Bluetooth component in the broadcast mode is connected to the mobile terminal over time, it will enter the sleep mode; When the Bluetooth component is in the transparent transmission mode, if the mobile terminal actively disconnects or the Bluetooth component detects that there is no Bluetooth data communication for a long time, the Bluetooth component will disconnect the Bluetooth, exit the transparent transmission mode, and enter the broadcast mode. Specifically, the Bluetooth component can have separate buttons, or can share the buttons of the positioning component. By operating the buttons, the Bluetooth component in the sleep mode can be awakened to enter the next working mode.
[0042]According to an embodiment of the present invention, the online inspection system further includes a monitoring center, which communicates with the mobile terminal to obtain information of the informationized miner's lamp through the mobile terminal, and perform online monitoring based on the information of the informationized miner's lamp. Through the monitoring center, the working status of the informationized miner’s lamp and the location of the underground workers can be learned in time, and the danger can be dealt with in time, which provides protection for the safety of underground workers.
[0043]Optionally, the positioning component is a UWB positioning component, and the informationized miner's lamp uses the positioning function of the UWB positioning component and the UWB positioning component to perform data interaction with the mobile terminal to realize the mobile base station function. UWB has many advantages such as strong anti-interference performance, high transmission rate, extremely wide bandwidth, low power consumption, and low transmission power. UWB accurate positioning has a large coverage area, and the coverage radius of a single base station is more than 500 meters. The UWB positioning component can accurately locate underground workers. Through the Bluetooth component, accurate position information can be sent to the mobile terminal, and the transmission rate is high. Users of informationized miner's lamps can accurately know their location.
[0044]In summary, according to the online inspection system of the embodiment of the present invention, the Bluetooth component is an intermediate link for data interaction between the positioning component and the mobile terminal. Through the online inspection system, not only the informationized miner's lamp has a mobile base station mode, but also realizes human-computer interaction, which has the advantages of easy management, lower costs, and timely detection of problems.
[0045]The online inspection method based on Bluetooth transmission according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
[0046]Such asimage 3As shown, the online inspection method based on Bluetooth transmission according to the embodiment of the present invention can be applied to any one of the above-mentioned online inspection systems, and the online inspection method includes the following steps:
[0047]S1. Turn on the Bluetooth in the mobile terminal;
[0048]S2. Turn on the Bluetooth component in the informationized miner's lamp by pressing the button, the Bluetooth component exits the sleep mode and enters the broadcast mode, and the informationized miner's lamp sends out broadcast packets through the Bluetooth component to prepare to establish connection with the Bluetooth of the mobile terminal;
[0049]S3. After the Bluetooth component in the informationized miner's lamp is successfully connected with the mobile terminal, the Bluetooth component enters the transparent transmission mode, so that the positioning component can interact with the mobile terminal according to the Bluetooth communication connection.
[0050]Optionally, switch between sleep mode, broadcast mode and transparent transmission mode. The sleep mode can make the Bluetooth component in the lowest power consumption mode, so that the core of the Bluetooth component and all running tasks are stopped and only responds to keystrokes. GPIO level wakeup; broadcast mode can make the Bluetooth component work in slave mode, and send broadcast packets to wait for Bluetooth connection with the mobile terminal, and after the connection is successful, the Bluetooth component enters the transparent transmission mode; the transparent transmission mode enables the Bluetooth component to control the power Level changes to change the Bluetooth connection state, so that the Bluetooth component can realize the data interaction between the positioning component and the mobile terminal.
[0051]Preferably, when the Bluetooth component in the sleep mode detects a key level change, it will exit the sleep mode and enter the broadcast mode; when the Bluetooth component in the broadcast mode is connected to the mobile terminal over time, it will enter the sleep mode; when the Bluetooth component is in the transparent transmission mode If the mobile terminal actively disconnects or the Bluetooth component detects that there is no Bluetooth data communication for a long time, the Bluetooth component will disconnect the Bluetooth connection, exit the transparent transmission mode, and enter the broadcast mode.
