Indication method, detection method, indication device, detection device and equipment of running status

Abstract

The invention discloses an indication device of a running status. The indication device of the running status comprises a control unit, a coding / modulating unit, a logic AND unit, a driver and an indication lamp. Further disclosed is a detection device of the running status. The detection device of the running status comprises an optical detection unit, a demodulating / decoding unit and a display unit. Further disclosed are an indication method, a detection method and equipment of the running status. Extra hardware interfaces are not required to be added on a tested device, the multiple running statuses of the tested device can be displayed to users, and therefore the monitoring and detecting requirements to field devices are met, and the indication device, the detection device, the indication method, the detection method and the equipment have large advantages in application when the multiple complex running statues of the devices are monitored.

Description

technical field [0001] The invention relates to detection technology in wireless communication, in particular to an operation state indication and detection method, device and equipment. Background technique [0002] More and more communication devices are provided with light-emitting diode (LED) indicator lights, and people can conveniently judge the operating status of the equipment by means of the LED indicator lights of the equipment. The LED indicator light can indicate various operating states of the device through color, on and off (always on or off), flashing, etc. Due to the persistence of vision of the human eye (when the image seen by the human eye disappears, the The eye can continue to retain its image for about 0.1-0.4 seconds, this phenomenon is called persistence of vision), the flicker frequency that the human eye can distinguish is limited, and there must be a large enough difference to make the human eye correct Therefore, the higher frequency LED indicat...

Problems solved by technology

The LED indicator light can indicate various operating states of the device through color, on and off (always on or off), flashing, etc. Due to the persistence of vision of the human eye (when the image seen by the human eye disappears, the The eye can continue to retain its image for about 0.1-0.4 seconds, this phenomenon is called persistence of vision), the flicker frequency that the human eye can distinguish is limited, and there must be a large enough difference to make the human eye correct Therefore, the higher frequency LED indicators cannot be recognized by human eyes. In addition, in order to facilitate maintenance, the definition of LED flashing lights is usually required to be simple and clear in the engineering maintenance site. In this way, the number of LED indicators indicating the operating status of the equipment is also required restricted

[0003] When the field application of radio frequency identification (RFID, Radio Frequency Identification) passive UHF reader fails, it is usually necessary to detect various operating information such as power supply, temperature, antenna, interface, and standing wave ratio of the reader and Reading, in order not to affect the normal operation of the reader, the circuit cannot be detected by opening the reader or occupying the working network of the reader. The status can only be read through the LED indication on the reader. The number of LED indicator lights is limited, and various operating states cannot be defined. As a result, the information that equipment maintenance personnel can read through the LED indicators of the reader is limited, and it is difficult to meet the indication and detection needs of various operating states, thus causing serious damage to equipment maintenance.
