Description

System and method for online monitoring and maintaining filter Technical Field The invention relates to the technical field of heat dissipation equipment, in particular to a system and a method for on-line monitoring and maintenance of a filter. Background With the advancement of informatization technology, artificial intelligence has become an indispensable part of social development, and data centers serve as physical carriers thereof and play a key role. And the CDU is used as a cold energy distribution unit of the data center and plays a vital role in the normal operation of the data center. The abnormal judgment of the running of the CDU system of the current data center plays a vital role in the normal running of the whole data center, and the traditional CDU has a water pump redundancy design, and one water pump is connected with one set of pipelines and filters, as shown in figure 1. The filter can filter impurity etc. in the secondary side water route operation process, and the filter both ends are equipped with butterfly valve or other valve class, and the effect of valve is for cutting off the water route when the filter needs to maintain, changes the filter screen. However, the monitoring and maintenance of conventional CDU internal filters has the following problems: 1. the state of the filter cannot be monitored on line, and the blocking state of impurities in the waterway cannot be well judged; 2. In the maintenance process of the filter, the filter screen of the filter is replaced after the valve is manually operated, and the filter must be attended; 3. in order to maintain the filter, the two waterways are independent and the water pump resource can not be well utilized by the double redundancy design of the water pump.
