Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to a split type elevator communication system capable of being remotely monitored.
Background
The dependence on mobile communication networks is getting more and more severe, however, the indoor area is always a difficult point for signal coverage. The urban population density is large, high-rise buildings are very large, and the phenomenon that no signal exists in an elevator often occurs. The elevator coverage system is used for solving the problem of elevator mobile network coverage. Elevator covering systems generally consist of a main machine unit, which is mounted above the elevator machine room or shaft, and a follow-up unit. The following unit is installed above the elevator car, and the main unit and the following unit spatially transmit mobile communication network signals. When the elevator car is at the top, the car unit and the main machine unit adjust and reduce the system gain, and the system is guaranteed not to be self-excited. When the elevator car unit moves downwards, the system quickly adjusts and increases the gain, keeps the output radio frequency power of the elevator car unit stable, and ensures that a user mobile network signal in the elevator is good.
However, the stability of the communication device relates to the satisfaction of the user, which can affect the public praise of the operator. The first time processing when the equipment is abnormal can minimize the negative influence of the event on the user compared with the process of waiting for the complaint of the user to be processed. The remote monitoring function is a basic function of the communication apparatus. The split type elevator covering system with the wireless coupling access signal comprises two stages of equipment, and the simple method is that a monitoring modem is arranged in a host unit and a follow-up unit, and a network management platform is connected with an elevator communication system by using an SIM card in a short message or GPRS network mode, so that the elevator covering equipment (the host unit or the follow-up unit) can be remotely configured, parameters can be adjusted and the like. The network management platform can receive the abnormal alarm information of the host unit or the follow-up unit in time and prompt the user to reduce the damage degree caused by the fault.
However, this method requires that the host unit and the slave unit respectively have built-in monitoring modems and SIM cards are placed in the monitoring modems, which occupies more traffic card resources and is higher in cost. The cost difference is even more significant in the case of one host to multiple slave units.
Therefore, it is desirable to provide a system for real-time monitoring of signals in a split elevator communication network at a lower cost.
