Abstract

The invention discloses a transmitting base station with a water-cooling monitoring device. The transmitting base station comprises a wireless signal transmitting system, a microwave optical fiber transmission device, a water-cooling device and the water-cooling monitoring device, the microwave optical fiber transmission device is used for communication between the main base station and the plurality of sub base stations; the water cooling devices are respectively arranged in the wireless signal transmitting systems; the water cooling monitoring device comprises a main controller unit, a communication unit, a phase sequence protector, a switching power supply, an analog quantity input module and a sensor. According to the invention, the water cooling device is adopted to dissipate heat ofthe high heating element, and the water cooling monitoring device realizes control of key equipment of the water cooling device and process processing of various alarm signals according to control requirements; phase discrimination and amplitude monitoring are directly carried out on reference signals returned by the sub-stations, absolute full phase compensation of optical links of the sub-stations is not needed, only relative compensation among the sub-stations needs to be carried out, and the phase consistency among the sub-stations is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of signal transmission, and in particular relates to a transmitting base station with a water-cooled monitoring device. Background technique [0002] At present, in multi-site distributed microwave signal transmission base stations, it is necessary to transmit high-stability microwave signals between the main base station and the base station. In the case of long-distance transmission and high environmental adaptability, especially in the transmission of broadband microwave signals During the process, the continuous phase adjustment range needs to reach hundreds of nanoseconds. At this time, it is very difficult to ensure the phase consistency of the broadband microwave signal, and the transmission base station generates a lot of heat. Most of the water-cooling monitoring systems in the prior art are controlled by logic circuit boards and low-voltage electrical appliances. Analog signal sensors cannot collec...
