If the specific situation of the other end is not known in the power supply system project by single construction work. The failure of normal communication is a serious safety hazard. How to solve the problem and solve the problem of mutual communication between stations, so that the construction work is safer and more efficient.
The subway temporary communication modes in the prior art include a mobile phone + interphone mode, a network system setting mode and a temporary telephone system setting mode.
The method comprises the following steps of (1) adopting a mobile phone + interphone mode: each time the communication between stations is carried out, three persons are required to be arranged as special communication personnel for each station. Each station is provided with one mobile phone and three interphones. With a corresponding increase following the participation of the station. The communication is delayed, repeated, simple and stable in connectivity, but the specific communication quality needs the language expression capability of a transmitter. The equipment in the system consumes about 1.86 ten thousand yuan per station in terms of communication and takes about 65 days per station from the installation to the reliable operation state.
Mode of setting up temporary telephone system: the early-stage erection requires manpower, and the later-stage use does not need. Each station is configured with a telephone, and communication service fees are paid to the operators according to the stations in the follow-up process every month. The communication basically has no delay, the first stations have better effect, and the subsequent stations have longer lines, so that the communication cannot be realized, and the subsequent stations use the traditional mode. The equipment in the system consumes about 1.57 ten thousand yuan per station in terms of communication and takes about 55 days per station from installation to reliable operation.
The method for setting the network facing system comprises the following steps: the early-stage erection requires manpower, and the later-stage use does not need. Each station is provided with a network system, and the network service fee is paid to the operator according to the station in the follow-up process every month. The communication effect is better, and the function is comparatively abundant, but the network is disconnected frequently, and it is comparatively complicated to maintain to later stage is with traditional mode. The equipment in the system consumes about 1.49 ten thousand yuan per station in terms of communication and takes about 55 days per station from installation to reliable operation.
