The working process of the mining portable positioning transceiver specifically comprises the following steps:
s1: the mining portable positioning transceiver is in a low-power-consumption standby mode in an initial state, the mobile terminal and the mining portable positioning transceiver are in wireless connection through the Bluetooth module 32, and the mobile terminal sends a mode instruction to control the mining portable positioning transceiver to execute a corresponding working mode.
It should be noted that the mobile terminal is an intrinsically safe mobile phone carried by a worker, the worker can select to establish bluetooth connection with the mining portable positioning transceiver after opening the intrinsically safe mobile phone, and the intrinsically safe mobile phone can send a mode instruction to the mining portable positioning transceiver through bluetooth. For example, when the intrinsically safe mobile phone sends a card searching instruction, the mining portable positioning transceiver enters a card searching mode, the mining portable positioning transceiver can search for a plurality of nearby tag cards to communicate, and upload the information of the searched tag cards to a display interface of the intrinsically safe mobile phone through bluetooth, so that a worker can conveniently check or modify the information. The mining portable positioning transceiver of this embodiment can carry out three kinds of mode: the system comprises a locator mode, a navigation mode and a wireless upgrading mode. The mode commands for the three operation modes are shown in table 1, and comprise a start bit, a serial-secret array, a mode code, a spreading code, a check code, and an end bit, wherein different values (e.g. 1, 2, 3) of the mode code represent the locator mode, the navigation mode, and the radio upgrade mode, respectively. And after the Bluetooth is disconnected for a long time, the Bluetooth is returned to a low-power consumption standby mode by default.

S2: when the mobile terminal controls the mining portable positioning transceiver to execute the locator mode, the UWB positioning module 33 searches for nearby UWB tag cards, performs polling and accurate ranging on all the searched UWB tag cards, and uploads real-time data obtained by the polling and accurate ranging to the mobile terminal.
It should be noted that the mining portable positioning transceiver may further include an RFID positioning module 36, and when the mining portable positioning transceiver executes the locator mode, the card search is performed first. For example, the UWB positioning module 33 may search for nearby UWB tag cards, and the RFID positioning module 36 may search for nearby RFID tag cards. The UWB positioning module 33 may perform polling and accurate ranging on all the searched UWB tag cards. The RFID positioning module 36 has no function of precise distance measurement, and the embodiment reserves the RFID positioning module 36 so as to be compatible with an RFID tag card which is arranged before in a mine. The UWB positioning module 33 and the RFID positioning module 36 can obtain information such as a card number, an electric quantity, an alarm state, and the like of the tag card when searching for the card. The UWB positioning module 33 may measure the distance of the UWB tag card by using a tof (time of flight) principle, obtain the flight time of the electromagnetic wave by recording a timestamp from the time when the electromagnetic wave is transmitted from the portable positioning transceiver for mining to the time when the electromagnetic wave is received by the UWB tag card, and then obtain the distance between the portable positioning transceiver for mining and the UWB tag card by multiplying the flight time by the propagation speed of the electromagnetic wave. The mobile terminal can also perform card number modification or alarm state setting on the tag card after obtaining the information of the tag card, the card number modification can facilitate the unified management of all the tag cards by workers, the alarm state setting enables the tag card to emit buzzer and vibrate when the tag card triggers the alarm, the appointed tag card can emit the buzzer and vibrate after the card number alarm command is issued, and a user can conveniently and quickly find the appointed tag card from a plurality of tag cards.
S3: when the mobile terminal controls the portable positioning transceiver for mine to execute the navigation mode, the positioning base station arranged underground can accurately measure the distance of the portable positioning transceiver for mine through the UWB positioning module 33 to obtain a distance value, meanwhile, the nine-axis sensor module 34 sends the sensing data of the portable positioning transceiver for mine measured in real time to the positioning base station, the positioning base station uploads the distance value and the sensor data to the personnel positioning server through the ring network, and the personnel positioning server calculates the accurate coordinate of the portable positioning transceiver for mine according to the distance value and the sensor data.
It should be noted that the nine-axis sensor module 34 includes a three-axis accelerometer, a three-axis angular velocity meter, and a three-axis magnetometer, where the three-axis accelerometer is used to measure the acceleration of the portable positioning transceiver for mine, the three-axis angular velocity meter is used to measure the angular velocity of the portable positioning transceiver for mine, and the three-axis magnetometer is used to measure the earth magnetic field. The underground positioning base station has its own coordinate position in the underground map, and the distance value between the mining portable positioning transceiver and the positioning base station can be measured according to the UWB positioning module 33. The personnel positioning server can calculate the current initial coordinate of the mining portable positioning transceiver according to the distance value. However, since the mining portable positioning transceiver is carried by the worker, the mining portable positioning transceiver may move or rotate, so that the calculated preliminary coordinates may have a deviation. Therefore, the initial coordinate is corrected by combining the angular velocity, the acceleration and the earth magnetic field data measured by the nine-axis sensor module 34, the current accurate coordinate of the mining portable positioning transceiver can be obtained, the error of the obtained accurate coordinate is not more than 0.1m, and the new technical requirements are met. The staff can look over the current accurate coordinate in real time through the 3D navigation APP who installs in this ampere of type cell-phone to can search for the destination site and carry out route planning and navigation. Because the underground roadway is very complex and the environment is very bad, if the current position cannot be accurately determined, errors may occur in the path and navigation to the destination station, so that the staff cannot accurately arrive at the destination, the working efficiency is affected, and potential safety hazards may exist.
S4: when the mobile terminal controls the mining portable positioning transceiver to execute the upgrading mode, the UWB positioning module 33 can establish upgrading connection with the underground equipment A to be upgraded and send the upgrading program package to the equipment A to be upgraded, and the equipment A to be upgraded automatically carries out program upgrading after receiving the upgrading program package.
It should be noted that, when the downhole device only has the UWB function, the UWB positioning module 33 of the mining portable positioning transceiver may establish an upgrade connection with the device a to be upgraded through UWB. When the underground equipment only has the RFID function, the RFID positioning module 36 of the mining portable positioning transceiver can establish upgrading connection with the equipment B to be upgraded through RFID. Generally, when upgrading, because the type of the device to be upgraded is clear, only one module is used for establishing upgrading connection, but from the power consumption perspective, if the device to be upgraded has the functions of RFID and UWB, the device to be upgraded preferentially tries to establish upgrading connection in the RFID mode with lower power consumption, and if the device to be upgraded cannot establish connection successfully, the device to be upgraded tries to establish upgrading connection in the UWB. After receiving the upgrade program package with the specified version, the device to be upgraded can automatically enter an upgrade mode to update the hardware program for itself. The equipment to be upgraded has a preset upgrading function, and can be upgraded without sending an upgrading operation instruction by the mobile terminal, namely, the mobile terminal only needs to send a complete upgrading program package, so that the upgrading method is simple and convenient.
The program upgrading specifically comprises the following steps:
t1: loading a program package: and sending the local upgrading program package in the memory of the mobile terminal to the mining portable positioning transceiver through Bluetooth.
T2: and number section issuing: in a program upgrading interface of the mobile terminal, a worker sets an equipment ID number segment range to be upgraded and sends the equipment ID number segment range to the mining portable positioning transceiver.
T3: establishing an upgrading connection: the mining portable positioning transceiver establishes upgrading connection with the equipment to be upgraded of the accessory through the UWB positioning module 33 or the RFID positioning module 36, so that the equipment to be upgraded enters a state of waiting for receiving an upgrading program package.
T4: starting upgrading: and after receiving the upgrading program package, the equipment to be upgraded carries out program upgrading.
T5: and (3) state inspection: in the upgrading process, the states of the upgraded equipment are patrolled in real time, for example, the upgraded equipment waits for upgrading, the upgraded equipment is upgraded and the upgraded equipment is finished, the state information is uploaded to the mobile terminal, the mobile terminal carries out state marking on each piece of equipment to be upgraded according to the state information, for example, red indicates that the upgrading is waited for, yellow indicates that the upgrading is finished, and green indicates that the upgrading is finished, so that a worker can conveniently distinguish the upgrading process.
In the present embodiment, the three operation modes are divided from the purpose of use, but require cooperation with each other in a specific operation process. For example, the locator mode is also started in the navigation mode, and the nearby tag cards are searched in real time and the state information of the tag cards is counted, so that the information of nearby people can be conveniently checked in real time. One tag card represents one person information, and the two modes are started simultaneously, so that the time can be saved, and the working efficiency is improved. When the wireless upgrading mode is entered, if the upgrading object is a tag card, the locator mode is simultaneously started, the transmitting power is adjusted to be maximum, the tag cards nearby are searched as much as possible, upgrading connection is established with the tag cards, the indicator lamp on the tag card is changed into red and is normally on to enter the upgrading state, and after the upgrading is completed, the indicator lamp is changed back to green and flickers for one second, namely, the normal working state is achieved.
In conclusion, the mining portable positioning transceiver device is small in size, easy to carry and flexible in working mode, can be combined with a mobile terminal through a special casing for use, can also be fixed at positions such as a belt of a worker through a buckle, and is small, exquisite and light. The device can independently complete the search and the positioning of nearby tag cards, and can report related data after establishing communication connection with any mobile terminal through Bluetooth, thereby improving the problems of hardware solidification, difficult maintenance and the like of the all-in-one machine. This device function is abundant, and the mode is various, is connected the back with mobile terminal and this device bluetooth, and the staff only need operate in mobile terminal can accomplish functions such as tag card search and management, position service system navigation in the pit, wireless upgrading of underground equipment, accords with the trend and the trend of coal mine technical development.
