Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The inventor finds that, in the prior art, when a B line of a normal output circuit of a user is grounded, current output by the B line flows to the ground through the B line, as shown in fig. 1, the current output by a voice gateway cannot reach a telephone to cause a user line fault, and is unavailable; the manual repair is time-consuming and labor-consuming, and the efficiency is low.
In order to solve the above problems, various non-limiting embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, fig. 1 shows a method for detecting and processing a line fault in an analog telephone system according to an embodiment of the present invention, the method includes the following steps;
step S10: the telephone is connected with an analog chip of the voice gateway through an A line and a B line in advance, the line voltage of the A line is set to be 0V, the line voltage of the B line is set to be-48V, and the line voltage of the A line and the line voltage of the B line are set to be-48V; the telephone is in normal conversation.
In the invention, as shown in figure 3, a telephone is connected with an analog chip of a voice gateway through an A line and a B line in advance, the voltage of the A line is set to be 0V, the voltage of the B line is set to be-48V, and the voltages of the A line and the B line are set to be-48V; the telephone is in normal conversation.
For example, as shown in fig. 3, a telephone is connected to an analog chip of a voice gateway through an a line and a B line according to a normal output circuit in advance, the voltage of the a line is set to be 0V as a ground line, the voltage of the B line is reversed in polarity to be-48V, and the voltages of the a line and the B line are-48V; the telephone is in normal conversation.
Step S20: detecting the voltage value between the AB lines at regular time;
in the present invention, the B-line voltage is periodically (e.g., every 5 minutes) sensed.
For example, as shown in fig. 3, the voice gateway detects the voltage value between the a line and the B line at regular time; judging whether the voltage value between the line A and the line B is-48V or not; when the voltage value between the line a and the line B is not-48V, the subscriber line fault is determined as step S30.
That is, in the present invention, the voltage between the AB lines is-48V, when the B line is grounded, the B line is connected to the ground, the current in the B line flows to the ground, and the voltage between the AB lines becomes 0.
Step S30: when the voltage value output voltage between the AB lines is detected to be 0V, the B line is judged to be in ground fault;
for example, when the voice gateway detects that the voltage value output voltage between the AB lines becomes 0V, the B line is determined to be grounded, and the B line is determined to be a B line fault; and generates a fault signal.
When the B line of the normal output circuit of the user is grounded, the current output by the B line flows to the ground through the B line, as shown in fig. 1, the current output by the voice gateway cannot reach the telephone, so that the line of the user fails, and the user cannot use the line. Judging that the line B is grounded and is a line B fault; and generates a fault signal.
Step S40: when the voltage value output voltage between the AB lines is detected to be 0V, the A lines and the B lines are automatically controlled to perform polarity inversion, the line voltage A is controlled to be-48V, the line voltage B is controlled to be 0V, and faults are automatically repaired.
In the invention, when the output voltage of the voltage value between the AB lines is detected to be 0V and a fault signal is received, the line A and the line B are automatically controlled to carry out polarity inversion, the line A voltage is controlled to be-48V, the line B voltage is 0V, and the fault is automatically repaired.
When the voltage value output voltage between the AB lines is detected to be 0V, automatically controlling the A lines and the B lines to perform polarity inversion according to a fault signal, controlling the voltage of the A lines to be-48V, and controlling the grounding voltage of the B lines to be 0V;
and controlling the voltage of the line A and the line B to be restored to-48V, wherein the current output by the line A can normally pass through the telephone and return to the analog chip through the line B of the ground wire to form a normal line path, and the automatic fault repairing is completed.
The invention utilizes the polarity inversion function of an analog chip, wherein the polarity inversion function is to invert the voltage of a user, for example, the voltage before an AB line is 48v, and the voltage after the polarity inversion is-48 v, so that the output voltage of the AB line of the user is exchanged.
In the invention, when the output voltage of the voltage value between the AB lines is detected to be 0V, the A lines and the B lines are automatically controlled to perform polarity inversion, the voltage of the A lines is controlled to be-48V, the voltage of the B lines is controlled to be 0V, and the fault is automatically repaired.
As shown in fig. 3, if the voice gateway finds that the B line is grounded, the output voltage of the subscriber line can be changed through the reverse polarity function, and the output voltage of the a line is changed to (-48V) and the output voltage of the B line is changed to 0V through the reverse polarity function, so that the grounding of the B line (the 0V output of the B line is originally the ground line), which will not affect the line, and the current output by the a line can normally pass through the telephone and return to the analog chip through the ground line (the B line), thereby forming a normal line path.
In specific implementation, it is found that if the B line is grounded to cause a fault in the subscriber line, the faulty line may be configured through some configuration interface such as a command line, so that the line always keeps polarity inversion.
Therefore, the invention solves the technical problems of unavailable telephone, manual repair, time and labor waste and low efficiency caused by B line grounding of a POTS (plain old telephone service) circuit in the prior art. The invention can automatically repair the line fault of the analog telephone system and ensure normal conversation. The operation is simple and convenient, the manpower and material resources are saved, the fault repairing efficiency is improved, and the fault repairing cost is saved; and the realization is easy, and the reliability is high.
