Embodiment 1

[0027] Embodiment 1. This embodiment proposes a water heater communication fault detection method. The connection structure of the gas water heater used in this embodiment is as follows: figure 1 As shown, the gas water heater at least includes a main control module 11 and one or more operation modules 13 with power carrier communication function. The operation module 13 is connected to the mains, and the main control module 11 is connected to the carrier receiving module 14 through a weak current signal line. The carrier receiving module 14 is connected to the commercial power, and the operation module 13 and the main control module 11 communicate through the power line. The carrier receiving module 14 is used to receive the signal sent by the operation module 13 in the power line, and convert it to generate a weak current signal and send it to the main control module. 11. The water heater communication fault detection method in this embodiment includes the following steps:

Abstract

The invention discloses a water heater communication failure detection method, including the following steps: (11), an operation module collects a key signal, processes the key signal to generate a control command, and sends the control command to a carrier receiving module, and the carrier receiving module sends an answer signal to the operation module; (12), after receiving the control command,the carrier receiving module converts the control command and sends the converted control command to a main control module, and the main control module receives a converted signal sent by the carrierreceiving module, generates a confirmation signal, and sends the confirmation signal to the carrier receiving module; and (21), after receiving the converted signal sent by the carrier receiving module, the main control module generates a display signal, a display module sends a request signal to the main control module, and the main control module sends the display signal to the display module after receiving the request signal. According to the water heater communication failure detection method disclosed by the invention, the location where the failure occurs can be accurately positioned, the after-sales service personnel can be facilitated to judge which part is damaged, and the time and cost of maintenance can be saved.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a method for detecting communication faults of water heaters. Background technique [0002] At present, some water heaters, such as gas water heaters, need to install one or more operation modules at the water point because the installation location is not in the same room as the water point. At present, the gas water heater and its operation module generally use the power carrier communication method, which requires multiple communication transformations to control The gas water heater can be turned on and off, adjust the temperature, check the status information of the water heater, etc. The communication involves the communication between each operation module and the power carrier receiving module, between the power carrier receiving module and the main control board, and between the main control board and the display module. Communication, once a communication failure ...
