Problems solved by technology

Another example is the abnormal situation that the transmission line of the telephone is accidentally pulled out during the call, which leads to the interruption of the call
At present, in the prior art, there is no simple technical solution for reliable detection of various abnormal conditions of the telephone set, and at the same time, the abnormal conditions of the telephone set have not attracted enough attention, thus affecting the normal operation of the telephone set. use, and may even lead to a series of security issues

Embodiment 1

[0052] Embodiment 1. Parallel detection of telephone sets

[0053] When the microprocessor module 303 detects that the voltage data at the second moment on the transmission line of the telephone is different from the voltage data at the first moment, the change difference of the first voltage data is 0, and the second voltage data drops And the drop amount reaches the set first threshold, then it is judged that the telephone set enters a parallel state at the second moment, and the parallel state is a state in which the extension phone is off-hook during a normal conversation of the telephone set. Parallel detection here corresponds to Figure 4 The voltage and current change waveforms marked as 7, that is, when the extension is off-hook, the voltage on the transmission line of the local machine will remain unchanged, but the current will drop instantaneously.

Embodiment 2

[0054] Embodiment 2, the transmission line of the telephone is pulled out

[0055] When the microprocessor module 303 detects that the voltage data at the second moment on the transmission line of the telephone is different from the voltage data at the first moment, the change difference of the second voltage data is 0, and the first voltage data drops And the drop amount reaches the set second threshold value, then it is determined that the transmission line of the telephone set is pulled out at the second moment. Here the condition of detecting that the transmission line is unplugged corresponds to Figure 4 The voltage and current change waveforms marked as 14, that is, when the telephone transmission line is pulled out, the current signal on it will remain unchanged, and the voltage will drop instantaneously.

Embodiment 3

[0056] Embodiment 3, the off-hook detection of telephone set

[0057] When the microprocessor module 303 detects that the difference between the voltage data at the second moment on the transmission line of the telephone and the voltage data at the first moment is: the first voltage data drops and the amount of drop reaches the set third threshold , the second voltage data rises and the rising amount reaches the set fourth threshold, then it is judged that the telephone set enters the off-hook state at the second moment, that is, the off-hook action is performed at the second moment. Here, off-hook detection corresponds to Figure 4 The voltage and current variation waveforms marked as 5, that is, when the telephone is off-hook, the voltage on its transmission line will drop instantly, while the current will rise instantly.

Abstract

The invention discloses a detection method of a working condition of a telephone set. The detection method of the working condition of the telephone set is characterized in that the detection method comprises step 1: respectively acquiring voltage data corresponding to a first moment and a second moment at a preset time interval from the first moment on a telephone set transmission line; step 2: judging the working condition of the telephone set at the second moment according to the difference between the voltage data corresponding to the second moment and the voltage data corresponding to the first moment on the telephone set transmission line. The invention further provides a telephone set condition detection device, which mainly comprises an acquisition module for acquiring voltage data on the telephone set transmission line, and a judgment module for judging the working condition of the telephone set according to the difference between the voltage data corresponding to the two moments; the detection method and the detection device of the working condition of the telephone set provided by the invention can effectively detect whether an abnormal situation occurs in the telephone set at any moment or not, and are very suitable for telephone switchboard management mechanisms.

Description

technical field [0001] The invention relates to a detection method and a detection device for the working condition of a telephone set, which can effectively detect the working condition of the telephone set at any moment, and is extremely suitable for the telephone exchange management organization. Background technique [0002] With the rapid development of communication technology, its application to all aspects of social life has also greatly shortened the "distance" between people. Usually, communication technology includes wireless communication and wired communication. With the development of society, although wireless communication gradually replaces wired communication, wired communication has its unique advantages that wireless communication cannot be popularized, that is, better sound quality. The degree of influence by interference is small, and the signal transmission is stable. Therefore, the way of wired communication cannot be completely replaced by wireless ...
