Embodiment Construction

[0026] Such as Figure 1-2 As shown, the fire prevention monitoring method and system of the unmanned base station computer room, under normal load conditions, take the voltage of the power supply of the unmanned base station and compare it with the preset threshold voltage value. When the value of the voltage and the threshold voltage After comparing the values, if there is an abnormal current increase or load increase, an alarm signal will be output.

[0027] The value acquisition in the method refers to connecting the sampling resistor in series on the power line, and acquiring the value of the drop voltage of the sampling resistor.

[0028] The comparison in the method is by setting a voltage threshold value on the voltage comparator, and then comparing the drop voltage of the sampling resistor with the voltage threshold value.

[0029] The method can be realized by an unmanned base station machine room fire prevention early warning monitoring system, the system includes ...

Abstract

The invention discloses a fireproof pre-warning monitoring method for an unmanned base station and a system thereof. In the method, threshold values of a sample resistor and a voltage comparator are compared by two sets of power supply abnormal change monitoring circuits so as to obtain whether the power supply has abnormal changes and determine whether to warn or not. The method and the system first detect electric load increase, fire strike and jump spark on alternating current commercial 380V or 220V power supply, and secondly detect load increase (unknown increase) and direct current power supply short-circuit and fire strike on direct current 48V or 24V power supply which is outputted by a switch power supply cabinet for master equipment, so that the portent of a fire disaster in the equipment room of the base station can be found in advance, alternating current power supply can be automatically cut off in time, technicians can be dispatched for checking in the station in time, and fire hazards can be eliminated.

Description

technical field [0001] The invention relates to the technical field of communication base station equipment, in particular to a fire prevention early warning monitoring method and system for an unmanned base station computer room. Background technique [0002] At present, the wireless communication systems of the three major communication operators, mainly China Mobile, China Telecom, and China Unicom, are all composed of communication base station equipment distributed in cities and villages to complete the personal mobile phone call function. Most of these communication base stations are built unattended in the wild, and some belong to mobile prefab structures. [0003] At present, the base station equipment has an external alarm interface, and the base station equipment can send alarm information to the operation and maintenance system of the monitoring center according to the change of the interface voltage, which can realize remote monitoring. [0004] In the process o...
