Failure information displaying processing method and device and heater

Abstract

The embodiment of the invention provides a failure information displaying processing method and device and a heater. The method comprises the following steps of: detecting the failure type of a system; searching at least two-bit failure codes corresponding to the failure type; and circularly displaying each one-bit failure code of the at least two-bit failure codes by adopting a flash code, wherein each one-bit failure code is displayed by adopting the flash code with the same frequency, flash code display between adjacent bits of failure codes is stopped for a certain period of time, and the flash code display time of each one-bit failure code is the number of the failure code. By adopting the failure information displaying processing method and device and the heater provided in the embodiment of the invention, failure protection as well as expression and output of self-diagnosis information can be realized instantaneously, easily and conveniently at low cost, encoding is easy, higher consistence to the number checking habit of a user is realized, and the user can read failure information easily and accurately.

Description

technical field The invention relates to the technical field of fault information display, in particular to a fault information display processing method, device and heater. Background technique Electronic control devices with single-chip microcomputers as the core have been widely used in industrial equipment and civilian products, greatly improving the intelligence of the products, among which fault protection and self-diagnosis functions are its unique advantages. Fault phenomena or diagnosis results are generally notified to users and maintenance personnel in the following ways: 1. Adopt LCD screen technology, but the cost of LCD screen is high and limited by the ambient temperature. For example, it cannot be displayed normally below -25°C; 2. Use handheld diagnosis instrument, the cost of the equipment is higher, and the failure information cannot be reported in time and immediately. Another fault reporting method is the light flash code method. This method is low in ...

This method does not conform to people's habit of checking and counting at a constant speed. One fast and one slow will easily cause confusion and misjudgment, and increase the workload of writing flash code output drivers.
