Single-lamp multi-information indication method

Abstract

The invention relates to a single-lamp multi-information indication method which comprises the following steps: different fault signal codes are compiled, corresponding numbers of flashing times of a lamp are respectively compiled according to the different fault signal codes, flashing frequencies corresponding to different faults are set, and time intervals for cyclic flashing are set; a compiled and debugged program is burnt in a microprocessor or externally arranged in a storage; when detecting the existence of a fault signal, the microprocessor compares the fault signal with pre-stored fault signal codes and determines a fault signal code of the fault signal; the microprocessor sends pulse electric waves to an indication lamp control port based on the fault signal code according to the preset number of flashing times, a set flashing frequency and a preset time interval for cyclic flashing; the indication lamp flashes according to the pulse electric waves; and people judge fault content according to a pre-established specific fault comparison table. The single-lamp multi-information indication method has the advantages of reduction in cost of material of product, reduction in energy consumption, and low carbon and environment-friendliness.

Description

technical field [0001] The invention relates to a single-lamp multi-information indication method suitable for intelligent switches, electronics, electrical equipment, instruments and meters, mechanical equipment, etc., as fault category indication. Background technique [0002] At present, when faults occur in intelligent switches, electronic, electrical equipment, instruments, mechanical equipment, etc., in order to facilitate maintenance personnel to quickly determine the type of fault, fault type indicators or fault diagnostic instruments are generally used for diagnosis, and the latter is more expensive. , Only large repair shops have this kind of professional equipment. Due to its simplicity and convenience, fault category indication is still widely used on various instruments or equipment. The current fault category indication methods can be roughly divided into the following types, one is single-light single-fault indication, that is, each fault corresponds to one i...

Problems solved by technology

[0003] Although the method of single-light and single-fault indication is clear, it occupies a large display area and consumes a lot of materials. It is not very suitable for equipment that is becoming smaller and smaller. Although the method of directly displaying fault text or codes on the LCD screen is intuitive, However, the material cost is high, the energy consumption is large, and there is also the problem of occupying a large display area; the main problems of the method of displaying fault codes on the digital tube are that it is not intuitive, high in cost, and has a high failure rate, and it is prone to broken lines on the digital tube Assuming that the original fault code is 7, if the upper display line of the digital tube is not bright, the displayed result is 1, which does not match the actual fault code, so the result is unimaginable
