Background technique

The main purpose of power emergency communication is to meet the communication needs between on-site repair personnel and rear command and management personnel. The content of communication transmission includes voice, video and business data. In the existing technology, power emergency communication mainly relies on satellite communication, 3G communication and Long-distance communication methods such as ordinary mobile phone communication, and medium-distance communication technologies such as microwave communication. the

Satellite communication mainly has two forms: satellite phone and satellite command vehicle. The former is only used for voice calls, while the latter can transmit video and data. However, satellite communication is easily affected by weather, such as heavy rain and snow, but often such bad The weather is easy to cause a large power grid accident and needs the support of emergency communication technology. the

3G transmission requires base station access. In commercial office buildings with heavy traffic or many people surfing the Internet during holidays, base stations are prone to communication congestion, causing emergency communication interruptions or long delays. The construction of 3G networks in various cities is quite different, and some cities have poor infrastructure conditions. 3G networks can only meet the transmission of voice and small data volumes, and do not support real-time video transmission. the

Whether it is satellite communication or 3G mode, there will be expenses during the use process, especially the demand for video traffic is relatively large. the

Using microwave technology to achieve medium-distance communication, the voice, video, data and other information on the emergency repair site are connected to nearby substations, power business halls, office buildings and other places, and then transmitted to the command center through dedicated lines. The advantages of this method are: There will be no communication costs, but the installation of microwave communication equipment is a time-consuming and technically demanding process, and it must be powered by on-board power supply or power generation equipment. Emergency communication often requires two-way communication between the front and rear as soon as possible in an emergency , so there are many deficiencies in the use of microwave communication in the power emergency communication industry. the
