Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

First, the classification of the intercom provided by the present invention is explained: according to the hierarchical arrangement habit of fire fighting teams, the interphone is divided into two types and five levels.

Specifically, as shown in fig. 7:

color separation: different purposes are distinguished through the color of the machine body, and the machine body corresponds to rescue workers with different roles, so that the workers with different roles can quickly and accurately select equipment. The interphone is distinguished according to the colors of red, blue, yellow, green and black. Specifically, the method comprises the following steps: and red, commander type and leader use. Blue, battle type, and leader use. Yellow, battle type, used by the chief of the team. Green, battle type, and group leader. Black, battle type, used by firefighters. Red priority > blue priority > yellow priority > green priority > black priority.

Dividing the right: the method is characterized in that priorities are bound to different interphone hardware, the conversation priorities of the interphones in different levels are different, the higher the level is, the higher the priority is, and a user with high priority can interrupt the speech of a user with low priority.

Specifically, as shown in fig. 6:

and the first-level network corresponds to the public network, is communicated with the public network through the poc system and is used for leading the leaders to remotely command. And the secondary network is used for interphones held by the main team and the large and medium teams. The three-level network is used for interphones held by fire fighters in the large and medium teams, the group leader and the team leader. First level network priority > second level network priority > third level network priority.

Further, different interphones are classified to divide responsibility and authority, and the main differences of the types are as follows:

1. command type: the system is designed for commanders or teams and leaders, has a standard talkback function and a rear command center conversation function, has the capability of combining the rear command center conversation and the field direct call in one group, and supports the recording and playback of field command and scheduling voice.

2. The battle type: the system is designed for a middle captain, a team leader, a group leader or a fighter, supports the function of robbing words, is divided according to different levels, and supports the function of standard talkback.

3. Relay type: the method is mainly used for supplementing blind signal relay under the condition of insufficient talkback coverage (such as basements, large-scale complexes and the like) in complex scenes, and has relay forwarding capability.

Recording, namely recording outgoing calls and incoming calls to the SD card. Each interphone has a recording function, and voice in one session is stored in the SD card and is played if necessary.

And in the process of emergency call, the high-priority interphone can interrupt the call of the low-priority interphone and establish a new call with the low-priority interphone.

The ranking for the network includes: the first-level network is specially used for public network communication by using POC technology, and the second-level network and the third-level network are distinguished by using different frequency points.

In particular, the implementation of the secondary and tertiary networks is supported by various types of channels at the lower layers. Wherein, the common channel comprises a single frequency point. As shown in fig. 5, the relay channel includes two frequency points F1 and F2, and can work in two modes:

scanning mode: and scanning two frequency points F1 and F2 at the same time in idle, and if a call exists, selecting a better signal to access the call.

A forwarding mode: the two frequency points F1 and F2 are scanned simultaneously in idle time, if a call exists, a better signal is selected to be accessed into a conversation, and the signal is forwarded at the other frequency point according to a certain rule (interphone function).

The interphone with the high priority can interrupt the interphone with the low priority in conversation, and initiate a new conversation, so that the aim that the upper level command timely issues the lower level command is fulfilled. The call snatching function has priority division, and only the interphone with high priority can snatch the call of the interphone with low priority.

Embodiments of the present invention will now be described in detail:

it should be noted that, in the present technical solution, the priority of the network level is greater than the priority of the color. Specifically, since interphones of the same color may exist in two network levels, the network level priority is preferably considered during call preemption. For example: blue interphones exist in both the secondary network and the tertiary network, and the priority of the blue interphones belonging to the secondary network is higher than that of the blue interphones in the tertiary network under the condition. For another example: yellow interphones are arranged in the second-level network and the third-level network, blue interphones are arranged in the third-level network, and the priority of the yellow interphones in the second-level network is higher than that of the blue interphones in the third-level network. Correspondingly, if the red interphone with the highest priority is in the three-level network, the priority of the red interphone is also behind the black interphone in the two-level network.

In particular, the method comprises the following steps of,

the main call-robbing process is shown in fig. 1, and the call-robbing situation across networks is included in fig. 1:

for the local machine, pressing a call grabbing key PTT, judging whether the local machine is in a receiving state, if so, judging whether the network level of the local machine is higher than that of the transmitter, if so, transmitting an interrupt signaling to initiate a cross-network call grabbing process (refer to figure 4), otherwise, initiating a new call.

If the network of the local machine is not higher than the transmitter, judging whether the network level of the local machine is lower than the transmitter, if so, interrupting the failure of the opposite side, thereby failing to realize the call robbing; if not, judging that the priority of the local network is the same as that of the transmitter, judging whether the color level of the local network is higher than that of the transmitter, if not, interrupting the failure of the opposite side, thereby failing to realize the call robbing; otherwise, the color of the local machine is higher than that of the transmitter, an interruption signaling (carrying out same-level network session preemption) is sent to the transmitter, whether interruption is successful or not is judged, if yes, a new call is initiated, and if not, session preemption fails.

The same level network session is shown in fig. 2 and 3:

fig. 2 is a flow chart of the local device when initiating a call snatching:

the local machine continuously listens to the channel signal, if the first time slot has service, the second time slot is idle, if yes, the channel seizing frame is sent in the second time slot, and if not, the second time slot is idle, the operation is finished.

And waiting for a preset time, judging whether the first time slot of the local machine has no service or not, if so, successfully seizing the channel, and otherwise, failing to seize the channel.

Fig. 3 is a flow chart of the case where the transmitter side corresponding to fig. 2 is called for:

and the transmitter continuously transmits the service in the first time slot, judges whether a channel seizing frame is received in the second time slot, processes the channel seizing frame if the channel seizing frame is received in the second time slot, and continues to process the service in the first time slot until the service is finished if the channel seizing frame is received in the second time slot. And judging whether the processing of the channel seizing frame is finished, if so, immediately finishing the first time slot sending service and establishing a communication with the local machine according to the channel seizing frame, and otherwise, continuously processing the first time slot service until finishing.

The network scanning schematic diagram of cross-level network session preemption is shown in fig. 4:

the receiving interphone (transmitter) with low priority level must work in the dual-network channel to support the cross-network call robbery. The transmitter working in the dual-network channel processes the transmitted or received data, and monitors two frequency points (F3/F4) of the priority channel (corresponding to the first-level network) in real time in an idle time slot, and any frequency point stops transmitting or receiving voice after receiving a reverse interrupt signaling.

High priority intercom (robbing phone/native):

1. in the receiving state, after the PTT is pressed down in receiving, a reverse signaling is transmitted in an idle time slot (second time slot), then the local machine enters a waiting state, if the working time slot (first time slot) is detected to have no signal strength any more, the interruption is considered to be successful, then a new call is initiated, and the call grabbing process is completed.

2. In non-receiving state, the high-priority interphone (local) in different network segments can stay at a frequency point different from that transmitted by the transmitter, when the interphone works in an idle state, after the call grabbing PTT is pressed down, a reverse signaling is transmitted in an idle time slot, then the interphone enters a waiting state, if the working time slot has no signal strength, the interphone is considered to be interrupted successfully, then a new call is initiated, and the call grabbing process is completed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and these modifications or substitutions do not depart from the spirit of the corresponding technical solutions of the embodiments of the present invention.
