Alternating-current contactor type selection processing method and system

Abstract

The invention provides an alternating-current contactor type selection processing method and system. The method is used for performing data query and retrieval between a user side and a database server through an application server to complete type selection of an alternating-current contactor. The application server receives instruction information used for starting type selection and sent by the user side, receives one or more parameter information, of the alternating-current contactor, needed for alternating-current contactor type selection and sent by the user side, generates query statements in one-to-one correspondence to the parameter information according to the parameter information of the alternating-current contactor, retrieves a database in the database server according to the query statements, searches an alternating-current contactor type matched with the query statements, and finally returns the matched alternating-current contactor type to the user side. The alternating-current contactor type selection processing system can efficiently and accurately select the alternating-current contactor type matched with the conditions, so that no mistake is made to type selection, reliability in design is improved, and the most accurate type selection scheme is provided for a user.

Description

technical field [0001] The invention relates to the field of computers, in particular to a type selection processing method and system for an AC contactor. Background technique [0002] AC contactors are widely used as circuit control components in central air-conditioning systems. At the same time, central air-conditioning systems are used in various large buildings and public places. With the advancement of technology and the rapid development of central air-conditioning systems, the processing capacity of central air-conditioning systems is becoming more and more heavy when selecting AC contactors. In the process of design, installation and commissioning of a huge central air-conditioning system, it is necessary to continuously select the type of AC contactor. This process often involves many types of AC contactors and corresponding working condition information, and this work is often difficult. Any mistakes will consume a lot of human resources at the same time. [00...

Problems solved by technology

At the same time, central air-conditioning systems are used in various large buildings and public places. With the advancement of technology and the rapid development of central air-conditioning systems, the processing capacity of central air-conditioning systems is becoming more and more heavy when selecting AC contactors. In the process of design, installation and commissioning of a huge central air-conditioning system, it is necessary to continuously select the type of AC contactor. This process often involves many types of AC contactors and corresponding working condition information, and this work is often difficult. Any error occurs while consuming a lot of human resources

[0003] In the prior art, the selection of AC contactors used in central air conditioners mostly adopts the method of manual self-selection. This method sometimes leads to the wrong AC contactor selection due to calculation errors or search errors.

[0004] In general, the existing central air-conditioning system mainly faces the following problems when selecting AC contactors. First, the selection efficiency is low, and the processing speed of AC contactors through manual selection and calculation is low.

2. The selection error rate is high, and the selection of AC contactors through manual selection and user experience is easy to cause selection errors

3. It is not possible to provide more optimized and more selected models as a reference plan

Because the subjectivity of manual selection users has a greater impact

Therefore, for the existing technology, how to efficiently and accurately select the model of the AC contactor that meets the conditions, so that the selection will not be wrong, increase the reliability of the design and provide the user with the most accurate selection plan is a difficult problem to solve
