Intelligent gas water heater diagnostic system

Abstract

The invention relates to an intelligent gas water heater diagnostic system which is characterized in that the intelligent gas water heater diagnostic system comprises an analysis diagnostic module, awireless communication module and a remote service center; the analysis diagnostic module is connected with a controller of a gas water heater and can collect and detect operational parameters of thegas water heater in real time; the wireless communication module is connected with the analysis diagnostic module; and the analysis diagnostic module can collect the operational parameters of the gaswater heater in real time, divides failures of the gas water heater into at least two categories, namely, non-serious safe failures and serious safe failures according to the real-time operational parameters of the gas water heater, and then carries out treatment according to the two categories of failures correspondingly. Compared with the prior art, the intelligent gas water heater diagnostic system has the advantages that a user can check specific running conditions of the gas water heater through the analysis diagnostic module, and carries out simple operation according to a diagnostic result of the analysis diagnostic module, so that the difficulty of handling a part of failures of the gas water heater by the user voluntarily is lowered, the failure handling cycle is shortened substantially, the user is prevented from getting into a panic, and the number of times of on-site repair by service technicians is reduced.

Description

technical field [0001] The invention relates to an intelligent diagnosis system for a gas water heater. Background technique [0002] Gas water heaters have high safety requirements, and the controller will provide safety protection for various software and hardware faults. These software and hardware faults are divided into serious safety faults, performance-affecting faults, and faults that can be cleared after power-on. In the event of software and hardware failures, the controller will send out an alarm sound through the alarm and display the fault code on the display screen. When faced with this situation, users often panic or worry, and do not know the fault code. It is possible to contact after-sales service technicians for on-site maintenance, and after the service technicians come to the door, because the use environment may not be consistent with the fault, it is difficult to reproduce the fault; this processing method has the following disadvantages: [0003] 1. ...

Problems solved by technology

In the event of software and hardware failures, the controller will send out an alarm sound through the alarm and display the fault code on the display screen. When faced with this situation, users often panic or worry, and do not know the fault code. It is possible to contact after-sales service technicians for on-site maintenance, and after the service technicians come to the door, because the use environment may not be consistent with the fault, it is difficult to reproduce the fault; this processing method has the following disadvantages:

[0003] 1. For non-serious safety faults, users can continue to use after simple treatment, but the maintenance cycle of the existing treatment method is long, which affects the normal use of users;

[0004] 2. It is cumbersome to use the built-in operator of the gas water heater to make related settings. Most users do not have the habit of reading the product instruction manual or product installation and maintenance manual, and generally do not troubleshoot by themselves;

[0005] 3. The fault site is easy to lose, and it is difficult to reproduce the scene at that time;

[0006] 4. The fault diagnosis algorithm of the gas water heater itself is limited by the computing power and storage space of the controller, so it cannot detect complex faults, and the diagnosis algorithm cannot be upgraded;

[0007] 5. On-site maintenance by service technicians brings higher maintenance costs
