As shown in fig. 5, the method for controlling broadcast communication provided in the embodiment of the present application is applied to the communication host of the control system, and includes:
And 502, if the remote control operation is determined to be accepted, generating an access success instruction to the program controlled exchange, and receiving a dual-audio signal fed back by the program controlled exchange.
In this step, after receiving the play area signal, decoding the play area signal, converting the play area signal into a digital signal, and determining a dial number sent by the telephone from the digital signal.
The dialing number may be a numerical value, or a numerical value sequence formed by combining a string of numerical values according to a predetermined rule.
In this step, a play area corresponding to the received dial number is determined according to a preset correspondence between the dial number and the play area.
Here, each telephone number key is assigned with a special control function, and each key may correspond to a broadcast area, so as to control the communication host to broadcast in a designated area, and for each setting of the broadcast area, one key may correspond to one broadcast area, or one number may correspond to one broadcast area, and taking a key to one broadcast area as an example, the rule of correspondence between keys and broadcast areas may be set as: keys 1-6 represent areas 1-6, respectively, of the control system 100 broadcast outside; the ALL key represents selection of the ALL broadcast area, and the OFF key represents cancellation of the ALL area selection.
The descriptions of step 501, step 502, and step 505 may refer to the descriptions of step 402 and step 404 in step 401, and the same technical effect can be achieved, which is not described in detail herein.
Further, the acceptance of the remote control operation is determined by the following steps: separating a contact signal from the remote control signal; determining a priority of the contact signal and a priority of each of the other plurality of contact signals received simultaneously with the contact signal; detecting whether the priority of the contact signal is highest among a plurality of contact signals received at the same time; if the priority of the contact signal is the highest among the priorities of the plurality of contact signals received simultaneously, it is determined to accept remote control.
In this step, after receiving the remote control contact signal, determining the priority of the received remote control contact signal, determining the priority of other contact signals received while receiving the remote control contact signal, determining whether the priority of the remote control contact signal is higher than that of the other contact signals received while receiving, and if it is determined that the priority of the remote control contact signal is higher than that of the other contact signals received while receiving, that is, the priority of the remote control contact signal is the highest, determining to receive and receive remote control.
The priority of each type of contact signal is preset, when each type of contact signal is set, the contact signal is set according to different communication functions of a ship on the whole sea, on the ship, the contact signal corresponding to the early warning type of signal is the contact signal with the highest level, and when other contact signals are in communication control, the early warning type of contact signal can directly cut off other communication; in the embodiment of the application, the priority of the contact signal corresponding to the broadcast signal is after the contact signal of the early warning signal, and when the priority is higher than the priority of the received remote control contact signal, the communication host determines that the remote control is not accepted.
According to the control method for broadcast communication, after the remote control signal is received, whether remote control operation is received or not is detected; if the remote control operation is determined to be accepted, generating an access success instruction to the program controlled exchange, and receiving a dual-audio signal fed back by the program controlled exchange; determining a dialing number sent by the telephone based on a digital signal converted from a playing area signal in the dual-audio signal; and determining a playing area corresponding to the dialing number based on the preset corresponding relation between the dialing number and the playing area.
Like this, generate remote control signal after the phone receives predetermined special number, send remote control signal to the communication host computer through the stored program control switch and request broadcast remote control communication host computer agrees to receive the remote control after, the phone passes through the stored program control switch send the dual audio signal who includes broadcast area signal and audio signal extremely the communication host computer, the communication host computer is based on broadcast area signal confirms broadcast area, based on dual audio signal to broadcast area broadcast information that broadcast area signal indicates can reduce and increase equipment quantity along with the regional increase, helps saving the shared space of communication equipment.
