[0021] This invention addresses the wireless communication transmission of construction data at oil exploration sites. By using Sub-G wireless communication technology and low-power, low-cost communication chips, a self-organizing portable terminal device can autonomously form a communication network in uninhabited areas to complete the real-time transmission of exploration data.

[0022] The present invention will be further described below: A portable terminal device for self-organizing networks based on SUB-1G radio communication technology, wherein the portable terminal device for self-organizing networks combines a server, a base station, and a mobile application to participate in... Figures 1 to 6 The self-organizing network portable terminal device includes an antenna, a Si4432 communication module, a dual-serial-port MCU controller, a Bluetooth module, a power supply module, a lithium battery, and a charging module. The MCU controller is electrically connected to both the Bluetooth module and the Si4432 communication module. The Si4432 communication module is manufactured using Silicon Laboratories. The wireless module made with the SI4432 chip is typically used in sub-1G wireless communication technology. It is a low-power, multi-band wireless transceiver chip with an operating voltage of 1.9–3.6V, a 20-pin QFN package (4mm × 4mm), and can operate in four frequency bands: 315 / 433 / 868 / 915MHz. Internally, it integrates a diversity antenna, power amplifier, wake-up timer, digital modem, 64-byte transmit and receive data FIFO, and configurable GPIO. The Si4432 communication module wirelessly connects to the base station via the antenna, and the Bluetooth module wirelessly connects to the Bluetooth module of the mobile phone. The power supply module supplies power to the Si4432 communication module, MCU controller, and Bluetooth module. The self-organizing network portable terminal device charges the lithium battery via the charging module. This utility model is based on SUB-1G communication technology as a long-distance information transmission method. It adopts the mature Si4432 chip communication module and wireless Bluetooth as the data access method for various businesses at the oil exploration and construction site. It solves the data backhaul problem of various construction teams at the oil exploration and construction site through SUB-1G communication technology and wireless Bluetooth technology.

[0023] Among them, data is collected on the mobile phone. Data such as measurement, drilling, arrangement, seismic source, and chemical dosing in oil exploration and construction operations are input into the mobile phone. The mobile phone encodes the data into GBK and converts it into a fixed-format data packet. The data packet is then sent to a self-organizing network portable terminal device based on SUB-1G communication technology via Bluetooth.

[0024] Portable terminal devices in self-organizing networks forward, receive, store, and retrieve data.

[0025] Data forwarding: The Bluetooth data received by the device is transmitted to the radio frequency module based on the Si4432 chip via serial port, and then the radio frequency module broadcasts the data wirelessly.

[0026] Data reception: Data reception is the reverse of transmission. The RF module receives data packets and transmits them to Bluetooth via serial port. It also stores the received data. Bluetooth receives the serial data and sends it to the mobile phone, completing the data reception process.

[0027] Data storage and retrieval: The self-organizing network portable terminal device has a built-in MCU controller, which allocates a portion of flash memory for data storage. Data exceeding the storage space is overwritten and saved. Data is read via Bluetooth by sending the character "?", and deleted via the character "?".

[0028] The system's communication process is as follows:

[0029] Open the mobile app, input the collected production data, and use the phone's built-in Bluetooth communication function to send data to the Bluetooth module of the self-organizing network portable terminal device. The self-organizing network portable terminal device receives the data packet and sends it to the Si4432 communication module via serial port. The Si4432 communication module forwards the received data packet to the base station via antenna. If the base station has a public network, the data packet is sent directly to the server via TCP. If the base station does not have a public network, the data packet is forwarded to other base stations, which then send it to the server.

[0030] The self-organizing network portable terminal device is equipped with a self-locking switch, which is electrically connected to the EN pin of the power supply module. The self-locking switch controls the 3.3V power output to enable device operation. The input of the power supply module is connected to the lithium battery, and the charging terminal of the lithium battery is connected to the charging module.

[0031] The self-organizing portable terminal devices are wirelessly connected via antennas and Si4432 communication modules. The self-organizing portable terminal devices can form a self-organizing network and forward data through the Si4432 communication module, with a communication distance of 2-3km.

[0032] The base stations are wirelessly connected to each other, and the base stations communicate with the server via 4G or 5G signals. If a base station has a 4G / 5G network, it uploads data to the server via 4G / 5G. If there is no 4G / 5G network nearby, the base station forwards the data to other base stations, which then transmit the data back to the server via the 4G / 5G network using the TCP protocol. This entire process completes the data transmission for the construction operation.

[0033] The Si4432 communication module operates on a 433MHz channel, connects to the antenna via an SMA RF connector, and connects to the MCU microcontroller via a serial TTL port.

[0034] The MCU microcontroller has dual serial ports and uses either the ESP32 or STM32F103 series. The MCU microcontroller connects to the Bluetooth module via TTL serial port, and all serial ports have the same speed.

[0035] The Bluetooth module is a Bluetooth 2.0-based serial communication module with a serial TTL interface for data communication.

[0036] The power supply module stabilizes the lithium battery voltage to 3.3V and simultaneously powers the Si4432 communication module, MCU, and Bluetooth.

[0037] The above provides a detailed description of the portable terminal device for self-organizing networks based on SUB-1G radio communication technology provided by this utility model. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope.
