Method and device for adjusting frequencies of intercom apparatuses

A method for adjusting frequencies of intercom apparatuses, the method applied to a first intercom apparatus and comprising:

• sending an apparatus identification to a first terminal, wherein the apparatus identification is indicative of a sending apparatus, a speech signal being sent from the sending apparatus and received by the first intercom apparatus, the first intercom apparatus communicating directly with at least one second intercom apparatus associated with at least one second terminal without through the first and second terminals;
• if apparatus identifications of the at least one second intercom apparatus do not contain the apparatus identification sent from the first intercom apparatus, determining that there is an unknown speech signal at a current operating frequency of the first intercom apparatus;
• receiving an adjusting instruction sent from a first terminal associated with the first intercom apparatus, wherein the first adjusting instruction carries a target operating frequency, and the target operating frequency is determined when the unknown speech signal is detected at the current operating frequency of the first intercom apparatus;
• adjusting the current operating frequency of the first intercom apparatus to the target operating frequency according to the first adjusting instruction;
• and
• sending another adjusting instruction instructing at least one second intercom apparatus to adjust the current operating frequency to the target operating frequency.

A device for adjusting frequencies of intercom apparatuses, the device comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor;
• wherein the processor is configured to:
• receive an apparatus identification sent from a first intercom apparatus, wherein the apparatus identification is indicative of a sending apparatus, a speech signal being sent from the sending apparatus and received by the first intercom apparatus, the first intercom apparatus communicating directly with at least one second intercom apparatus associated with at least one second terminal without through the first and second terminals;
• if apparatus identifications of the at least one second intercom apparatus do not contain the apparatus identification sent from the first intercom apparatus, determine that there is an unknown speech signal at a current operating frequency of the first intercom apparatus;
• determine a target operating frequency;
• send a first adjusting instruction instructing the first intercom apparatus to adjust the current operating frequency to the target operating frequency;
• and
• send a frequency changing message to the at least one second terminal for controlling the at least one second intercom apparatus to adjust the current operating frequency to the target operating frequency, such that the first intercom apparatus communicates, at the target operating frequency, directly with the at least second intercom apparatus without through the first and second terminals.
