[0024] Functional Overview

[0025] Considering the problems in the related art that it is necessary to periodically go to the base station to remove dust from the heat exchanger and the maintenance cost is high, the embodiments of the present invention provide a method and system for detecting blockage of the air inlet of the heat exchanger. The method includes: the heat exchanger detects the rotation speed of the external circulation fan, and sends the detected rotation speed value to the network management center; the network management center compares the rotation speed value with a preset range to determine whether the external circulation air inlet is blocked.

[0026] The invention realizes the purpose of judging whether the external circulation fan is blocked by using the difference in wind speed between the two situations of the outer circulation fan being blocked and the air inlet not being blocked.

[0027] It should be noted that, in the case of no conflict, the em...

Abstract

The invention discloses a blocking detection method of an external circulation air inlet of a heat exchanger and a system thereof. The method comprises: a heat exchanger detects the rotation speed ofan external circulation fan and sends a detected rotation speed value to a network management center; the network management center compares the rotation speed value with a preset range so as to judgewhether the external circulation air inlet is blocked or not. The invention can solve the problems that the heat exchanger needs dedusting periodically on a base station site in the relevant technology and maintenance cost is high; thus, the invention can accurately and remotely judge the state of the external circulation air inlet of the heat exchanger and avoid aimless maintenance of the heat exchanger on the base station site, so that the invention not only effectively cleans the heat exchanger but also lowers the maintenance cost of equipments.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for detecting blockage of an air inlet of an external circulation of a heat exchanger. Background technique [0002] In the field of communication, outdoor base stations are more and more used in the global communication market due to their advantages of simple construction and low cost. The heat exchanger is a key component of the outdoor base station and is used for the heat dissipation of the system. The principle of the heat exchanger is to inhale the air outside the base station, then flow through the heat exchange core for heat exchange, reduce the temperature of the core, thereby reducing the internal problems of the base station. The heat exchanger external circulation air inlet refers to the inlet where the heat exchanger sucks in external air. When the air inlet of the external circulation is blocked due to wind, sand, dust, etc., the heat exchanger canno...
