Detailed Description
The invention will be further explained by means of embodiments in conjunction with the attached drawings.
Fig. 1 is a schematic diagram of an operating method of an intercom according to an embodiment of the present invention; as shown in fig. 1, in this embodiment, the method for operating an intercom provided by the present invention includes the following steps:
s101: when the interphone is in a power-saving mode, whether a carrier signal is carried on a channel is detected; if yes, executing step S102; if not, the present inspection flow is ended, the power saving mode is maintained, and the process returns to continue to execute step S101 after a predetermined time or immediately.
In the invention, the working states of the interphone are defined as two types: the system comprises a power saving mode and a normal working mode, wherein the power saving mode refers to a working state that the interphone does not receive carrier signals sent by external equipment and/or other interphones; correspondingly, the normal working mode refers to a working state of the interphone for receiving the external carrier signal.
When the intercom communication is performed, two or more interphones transmit/receive data information through the carrier signal, so that when the carrier signal appears on the working channel of one interphone, it means that there is an external call request to access the interphone, and at this time, step S102 is executed;
s102: and entering a normal working mode.
The mode that the intercom got into normal mode specifically is: the interphone awakens a communication function module of the interphone and enters a normal working mode of receiving and transmitting carrier signals; the communication function module herein refers to a module for implementing functions of receiving, processing, sending, etc. of the intercom, and the specific implementation mechanism and the working principle thereof are not the key points of the present invention, and are not described in detail in this embodiment.
Since the interphones of the same model share the same communication channel, in order to avoid the influence of the carrier signal calling other interphones on the interphone, the invention also provides the function of carrying out identity verification on the carrier signal, and only when the target interphone of the carrier signal is the interphone, the step S102 is executed, which is specifically as follows:
fig. 2 is a schematic diagram of an intercom operating method according to another embodiment of the present invention; as can be seen from fig. 2, in this embodiment, on the basis of the embodiment shown in fig. 1, specifically, after the determination result of step S101 is "carrier signal exists" and before step S102, the method for operating an interphone according to the present invention further includes:

since the embodiment shown in fig. 2 only adds step S201 to the description of the embodiment shown in fig. 1, other steps are the same as those shown in fig. 1, and are not repeated in this embodiment.
In order to implement the determination function of step S201 in the embodiment shown in fig. 2, the present invention provides various determination mechanisms, such as: adding identification information of the carrier signal source terminal in a carrier signal, detecting whether the identification information of the carrier signal source terminal is matched with the identification information of a communication terminal of the interphone by the interphone, when the carrier signal source terminal belongs to a communication terminal member of the interphone, the matching is successful, and the judgment result of the step S201 is whether a target receiving end of the carrier signal is self, and executing the step S102, wherein the identification information can be information which can uniquely determine and identify the identity of the interphone, such as the number of the interphone; adding a verification field in the carrier signal, detecting whether the verification field carried by the carrier signal is consistent with the verification field stored by the interphone, when the verification field carried by the carrier signal is consistent with the verification field stored by the interphone, matching is successful, the judgment result of the step S201 is whether the target receiving end of the carrier signal is the target receiving end of the carrier signal, and at the moment, executing a judgment mechanism of the step S102 and the like; in another embodiment, the present invention provides a method for determining whether a target receiving end of a carrier signal is itself according to identification information of the target receiving end carried by the carrier signal, with reference to fig. 3:

each interphone has unique identification information, and whether the target receiving end of the carrier signal is the interphone can be accurately judged according to the fact that whether the target address carried by the carrier signal is matched with the address of the interphone.
When the interphone supports multi-mode transmission, such as speech, image and data transmission, the user also needs to manually select the corresponding working mode to transmit and receive carrier signals with different frequencies, and for convenience of description, the normal working mode of the interphone is divided into two modes: a high speed mode and a low speed mode; these two normal operating modes will now be explained: in the high-speed mode, the megagrade spread spectrum code rate can be supported, and meanwhile, a data frame only has a structure of a spread spectrum modulation frame header and a spread spectrum modulation data section; the low-speed mode can support the spread spectrum code rate of several K to several hundred K, and the data frame has two structures of a spread spectrum modulation frame head and a spread spectrum modulation data section and a continuous phase modulation frame head and a continuous phase modulation data section.

At this time, according to the correspondence between the spreading code rate obtained in step S401 and the above, a normal operating mode corresponding to the spreading code rate of the carrier signal is selected, such as a first normal operating mode or a second normal operating mode, to wake up itself, and enter the selected normal operating mode.
In another embodiment of the present invention, the method for operating an intercom further includes:
when the interphone is in a normal working mode, detecting whether a carrier signal is carried on a channel or not; and if the carrier signal is not detected on the channel in the preset time period, entering a power saving mode.
In this embodiment, if there is no carrier signal on the channel of the intercom, it indicates that the intercom is not called in this period of time, and in order to save power, the intercom can be controlled to enter the power saving mode to save power; in order to ensure the accuracy of the judgment result, after the carrier signal is detected, whether the target receiving end of the carrier signal is itself can be further detected, if the target receiving end of the carrier signal is not itself, the carrier signal is considered to be absent, and certainly, the working mode of the carrier signal itself can be automatically switched according to the spreading code rate of the carrier signal of which the detected target receiving end is itself, and the like.
