Description
Technical Field
The invention belongs to the technical field of Bluetooth video transmission, and particularly relates to a data transmission system and method based on dual-mode Bluetooth in an underground tunnel.
Background
At present, China is increasing investment construction of underground comprehensive pipe galleries, and billions of underground comprehensive pipe galleries are constructed each year. However, many underground pipe gallery do not provide the forceful electric power for the safety consideration, also do not have the cell-phone signal, and the construction is patrolled and examined personnel and is got into the tunnel after, can't communicate with the external world, seriously reduces construction patrolled and examined personnel's work efficiency, and how to solve low-power consumption high rate communication problem in the underground tunnel has become a difficult problem of putting in the face of underground pipe gallery constructor.
Since power consumption of WiFi communication is too large compared with that of Bluetooth communication and the like, the method does not consider WiFi communication and is only realized from the perspective of Bluetooth technology. BLE is short for bluetooth Low Energy (bluetooth Low Energy); SPP (Serial Port Profile) is the standard Bluetooth mode of Bluetooth. The Bluetooth Serial port is based on SPP (Serial Port Profile), and can create a Serial port between Bluetooth devices for data transmission.
Bluetooth Low Energy (Bluetooth Low Energy) technology is a Low-cost, short-range, interoperable wireless technology, and operates in the unlicensed ISM radio frequency band of 2.4 GHz. It was designed from the beginning as an ultra low power wireless technology. It utilizes many intelligent means to minimize power consumption. The Bluetooth Low Energy has the following characteristics:
power consumption: the technology has extremely low operation and standby power consumption, and can work continuously for years even by using one button cell.
Speed: the ultra-short data packet under the data transmission rate of 1Mbps is supported, and the number of the ultra-short data packets is at least 8 and eight groups of bits and at most 27. All connections use the bluetooth 2.1 added deceleration breathing mode (sniff) to achieve ultra low duty cycle.
Frequency hopping: the use of adaptive frequency hopping common to all bluetooth specification versions minimizes cross talk with other 2.4ghz ism band radio technologies.
Delaying: it takes only 3ms to "complete" a connection (i.e., scan other devices, establish a link, send data, authenticate, and end appropriately). Whereas standard bluetooth technology requires hundreds of milliseconds to complete the same connection cycle.
Distance: the modulation index is improved, and the maximum range can exceed 100 meters (the distance is different according to different application fields).
Safety: and performing data packet encryption and authentication by using an AES-128CCM encryption algorithm.
Standard bluetooth has a maximum transmission rate of up to 24Mbps, but power consumption is high. Bluetooth low energy can be used for years with a button cell. In contrast, standard bluetooth technology typically requires the use of at least two AAA batteries (10 to 12 times the charge of button cells) and more often only for days or weeks at most. Therefore, the problem of low-power consumption and high-speed communication in the underground tunnel cannot be solved by simply using the low-power consumption Bluetooth or the standard Bluetooth.
