[0002] my country is a large maritime country with a vast sea area and abundant marine resources. More and more companies are turning their attention to the development of marine resources, resulting in an increasing number of various offshore operating platforms. Since the platform is far away from the land, the signals of various mobile base stations cannot cover the offshore operating platforms, resulting in the construction process of each platform being unsupervised, and the operators cannot communicate with the outside world and live an isolated life. Due to the complex and changeable marine environment, platform operation accidents occasionally occur, but the lack of real-time communication and supervision means has resulted in weak response and handling capabilities for emergency events on the platform, and the safety of offshore operators cannot be guaranteed. Therefore, offshore operating platforms are in urgent need of a communication method to enable communication between offshore operating platforms and land.

[0003] At present, the widely used maritime communication methods mainly include submarine optical cable communication, satellite communication and shore-based mobile base station communication. The submarine optical cable communication system mainly relies on submarine optical cables, but the laying cost of submarine optical cables is expensive, the construction period is long, and the maintenance is difficult; satellite communication has low bandwidth, high usage fees, difficult resource application, and long transmission delay; shore-based mobile base station communication has a short coverage range and no signal in the open sea. Therefore, submarine optical cable communication, satellite communication and shore-based mobile base station communication are not convenient to use as daily communication methods.

[0056] 8) Support free allocation of point-to-multipoint uplink / downlink bandwidth;

[0057] Support remote control, device software supports remote upgrade and wireless side upgrade, and supports installation of Chinese centralized control management software for Windows system.

[0058] The communication link between the relay base station module 2 and the working platform module 3 is called the access link. The access link is used to establish a long-distance and high-bandwidth link between the working platform module 3 and the fixed platform of the relay base station module 2. The access link is also suitable for microwave transmission. The relay base station module 2 is equipped with several access link base station transmission devices and several directional antennas, and the number of configurations can meet the coverage of the construction area. The working platform module 3 is equipped with several access link terminal devices 302 and several directional antennas to form omnidirectional communication.

[0059] Access link equipment (i.e. access link base station transmission equipment) main parameters:

[0060] 1) Working frequency band: 4.9GHz-6.0GHz, 4 radio frequencies;

[0061] 2) Rate bandwidth: ≥300Mbps (typical value for line of sight);

[0066] 7) Smart antenna technology: MIMO2x2 meets the requirements of high capacity, non-line-of-sight or mobile deployment;

[0067] 8) Network interface: provides a 10 / 100 / 1000Mbps Ethernet interface;

[0069] 10) Average power consumption: ≤18W;

[0070] Support remote control, device software supports remote upgrade and wireless side upgrade, and supports installation of Chinese centralized control management software for Windows system.

[0071] The signal strength of the microwave link between the main base station module 1 and the relay base station module 2 is calculated as follows: microwave link signal strength = transmission power + main base station antenna gain + relay station antenna gain - free space loss - feeder line loss - fading margin.

[0072] The calculation formula for free space loss Ld (in dB) is Ld=92.4+20lg(D)+20lg(F), distance D=35km, frequency F=5.8GHz. Substituting into the formula, the free space loss Ld=92.4+20lg(35)+20lg(5.8)≈138.55dB.

[0073] The product transmission power is selected as 27dBm, the antenna gain is selected as 32dBi, the combiner, feeder or waveguide loss is generally considered to be 2dB, and the attenuation margin is 8.75dB (according to the 70th announcement of the international FCCOET, for the 5GHz frequency, the signal attenuation is 0.25dB / km when the rainfall is 100mm per hour, and the signal attenuation is 8.75dB when the transmission distance is 35km.).

[0074] The signal strength of the 35km microwave link = 27 + 32 + 32 - 138.55 - 2 - 8.75 = -58.3dBm, and the full bandwidth receiving sensitivity of the equipment is -74dBm. Since -58.3dBm > -74dBm, the signal strength at 35km is sufficient to meet the full bandwidth requirement and has sufficient redundancy.

[0075] Similarly, the microwave link signal strength between the relay station module and the work platform module 3 (such as a construction vessel) is calculated as follows: microwave link signal strength = transmission power + relay station antenna gain + terminal antenna gain - free space loss - feeder line loss - fading reserve.

[0076] The calculation formula for free space loss Ld (in dB) is Ld=92.4+20lg(D)+20lg(F), distance D=30km, frequency F=5.8GHz. Substituting into the formula, the free space loss Ld=92.4+20lg(30)+20lg(5.8)≈137.25dB.

[0077] The relay station transmission power is selected as 27dBm, the relay station antenna gain is selected as 19dBi, the terminal antenna gain is selected as 17dBi, the combiner, feeder or waveguide loss is generally considered to be 2dB, and the attenuation reserve is taken as 7.5dB (according to the 70th announcement of the international FCCOET, for the 5GHz frequency, the signal attenuation is 0.25dB / km when the rainfall is 100mm per hour, and the signal attenuation is 7.5dB when the transmission distance is 30km.).

[0078] The signal strength of the 30km microwave link = 27 + 19 + 17 - 137.25 - 2 - 7.5 = -83.75dBm, and the receiving sensitivity of the device at 100Mbps bandwidth is -88dBm. Since -83.75dBm > -88dBm, the signal strength at 30km is sufficient to meet the full bandwidth requirement and has a certain redundancy.

[0079] 5.8GHz is a microwave frequency band with poor signal diffraction capability. According to the Fresnel zone calculation formula, when the height of both ends of the current platform is 25 meters, the full-speed communication distance of 5.8GHz is 23km. When the distance between the two platforms is 30km, some side lobes and main lobes of the wireless signal are blocked by the sea surface with strong absorption ability. The bandwidth is expected to be lower than 300Mbps for full-speed communication. However, the line-of-sight distance when the antenna height of the two platforms is 25m is 35.6km. When the two platforms are 30km apart, they have line-of-sight conditions and can still maintain a communication bandwidth of more than 150Mbps. When the antenna height reaches 43.4m, the full-speed communication requirements are met.

[0080] Then, according to the longitude and latitude of the relay station platform and the longitude and latitude of the working platform site, draw a distribution map of several coordinate points, and calculate the maximum angle α between the relay station and the working platform according to the scope boundary of the working platform construction; then according to the coverage range β of the directional antenna used by the relay station, if the α value is greater than the β value, the number of directional antennas used will be less, if the α value is less than the β value, a single directional antenna can meet the requirements; finally, the number of directional antennas set up on the working platform needs to be calculated based on the comparison values ​​of α and β based on the actual working platform.

[0081] The power supply design of the relay base station module 2 needs to select a suitable relay base station power supply according to the power consumption of the second backbone link microwave equipment, the first access link microwave equipment and the first POE switch 201 installed in the relay base station; the conversion efficiency of the solar controller 206 is generally calculated as 95%, from which the daily power consumption of the equipment can be calculated as: 24h×total power consumption of the equipment / 95%;

[0082] According to local meteorological conditions, the daily effective sunshine time is T; considering the charging efficiency and process loss, the solar energy conversion efficiency is calculated as 70%, the number of solar panels and the power generation power W are selected, and the daily solar panel power generation is calculated as: number of solar panels × W × T × 70%. The solar power supply system can meet the load of the relay base station module 2 to work continuously for 24 hours, and there is a surplus to charge the battery.

[0083] The battery pack 208 is composed of batteries selected according to the total power consumption of the relay station module. The output power of the battery pack 208 needs to be greater than the total power consumption of the relay station module and can support several days of continuous rainy days (based on the average number of continuous rainy days reported in the weather forecast).

[0084] The digital control unit 209 is used to remotely monitor the power generation of the solar panels, the power storage of the batteries, the power consumption of the loads, etc., and to control the power supply to the loads.
