For example, the low byte storage position D1D0 bit storage position of the 1 st register is used to indicate a broadcast control instruction for a pre-recorded broadcast, for example, [ D1D0] = [10] is used to indicate a broadcast control instruction for controlling the end of a pre-recorded broadcast, and [ D1D0] = [01] is used to indicate a broadcast control instruction for controlling the start of a pre-recorded broadcast.

The function code is used to indicate an operation to write to or read from one or more registers, and may be represented in one byte.
It may be understood that, in this embodiment of the present application, since the operator performs the broadcast control instruction issuing operation on the terminal of the integrated monitoring system, the integrated monitoring system may determine that the broadcast control instruction data corresponding to the broadcast control instruction issuing operation needs to be written into the register of the interface server, so that the interface server reads the broadcast control instruction data in the register, and by using the interface server to control the broadcast system, a function of a function code in an instruction packet including the broadcast control instruction data may be determined as: the broadcast control instruction data is written into a register.
Optionally, a plurality of system controls may be displayed in a display interface displayed on a display screen of the integrated monitoring system, where one or more system controls may be used to control a fire alarm system, a broadcasting system, or an environment and equipment monitoring system integrated in the integrated monitoring system, and when a control instruction needs to be issued to a certain system, an operator may use the system control to issue an instruction, where the system control may be a button or a file editing box. In the instruction issuing process, the comprehensive monitoring system can respond to the instruction issuing operation of an operator on the system control to acquire control instruction data, and control the system equipment corresponding to the system control to perform corresponding actions based on the control instruction data. The instruction issuing operation may be a touch operation of an operator on numbers or characters on the system control, or a number or character input operation through the system control.
It should be noted that, in the embodiment of the present application, the broadcasting system controls may include a plurality of controls, each for enabling the operator to select a broadcasting operation type, a broadcasting operation priority, a voice segment ID, a broadcasting content repetition number, a broadcasting microphone number, a broadcasting station number, and/or a train number to determine the broadcasting control instruction.

The instruction data packet also comprises a function code corresponding to the instruction data packet, and a message header determined by determining the data length and distributing transaction processing identifiers to the instruction data packet by acquiring the terminal identifiers of the integrated monitoring system. The function code is an operation for indicating writing or reading to one register.
The process of the comprehensive monitoring system responding to the instruction issuing operation to acquire the broadcast control instruction data can be as follows: after detecting the instruction issuing operation of the operator to the broadcast system control, the terminal of the comprehensive monitoring system responds to the instruction issuing operation of the operator to acquire broadcast control instruction data corresponding to the broadcast control instruction, wherein the broadcast control instruction data can be binary numbers. For example, the terminal of the integrated monitoring system detects a touch selection operation of the operator on the number 3 in the sub-control corresponding to the broadcast operation priority, determines the broadcast control instruction as the broadcast operation priority 3, and determines the broadcast control instruction data corresponding to the broadcast control instruction as 11.
For example, assuming an operation client of the integrated monitoring system, in response to an operator's instruction issuing operation to the broadcast system, determining the broadcast control instruction includes: and controlling the station 1 to broadcast the prerecorded broadcast content with the voice segment ID of 5, the broadcast priority of 3 and the repetition number of 2, and then the comprehensive monitoring system generates a broadcast control instruction by writing binary values into the storage positions of the corresponding registers after defining the storage positions of the registers according to a network protocol as shown in fig. 3. Binary data corresponding to station number 1 is written into a storage position D0 of the 4 th register, binary data 01 corresponding to the start of the control prerecorded broadcast is written into a storage position D1D0 of the 1 st register, binary data 000101 corresponding to speech segment ID 5 is written into a storage position D15-D8 in the high byte of the 2 nd register, or D10-D8 in the storage position D15-D8 in the high byte can be preferentially defined according to the numerical range of the speech segment ID for indicating the speech segment ID, for example, binary data 101 to D10-D8 are written for indicating the speech segment ID.
Binary data 11 corresponding to the broadcast priority 3 is written into a storage position D1D0 of the low byte of the 2 nd register, and binary number 10 corresponding to the repetition number 2 is written into a storage position D1D0 of the low byte of the 3 rd register.
When the instruction data packet is generated, the integrated monitoring system reads the broadcast control instruction data and the register number of the corresponding storage position in the register to generate the instruction data packet. The instruction packet corresponding to the above scenario includes the control instruction data 00000000 00000001 of the 1 st register; control instruction data 00000101 00000011 of the 2 nd register; control instruction data 00000000 00000010 of the 3 rd register; control instruction data 00000000 00000001 of the 4 th register; control instruction data 00000000 00000000 of the 5 th register; then the comprehensive monitoring system determines that the function code corresponding to the instruction data packet is 10, and the transaction identification in the message header can be 0102. And generating an instruction data packet after obtaining the broadcast control instruction data, the function code and the message header.
And 203, the interface server analyzes the instruction data packet according to the network protocol to obtain the broadcast control instruction data.
In this step, the process of the interface server parsing the command packet according to the network protocol to obtain the broadcast control command data may include: the interface server determines whether the instruction data packet is correct according to the network protocol, and when the interface server determines that the instruction data packet is the correct instruction data packet according to the network protocol, the interface server analyzes the instruction data packet according to the network protocol to obtain broadcast control instruction data.
The process of determining whether the instruction data packet is correct by the interface server according to the network protocol may be: after the interface server receives the instruction data packet, reading a message header, a function code and broadcast control instruction data in the instruction data packet, judging whether the message header, the function code and the broadcast control instruction data conform to identifiable message header, function code and broadcast control instruction data specified in a network protocol or not based on the network protocol, and if so, determining that the instruction data packet is a correct instruction data packet; if any one of the message header, the function code and the broadcast control instruction data does not accord with the data rule or standard specified in the network protocol, determining that the instruction data packet is an error instruction data packet, and the interface server needs to send an error instruction response data packet generated according to the analysis result of the network protocol to the comprehensive monitoring system. Wherein the error instruction packet includes: message header and fault function code, this fault function code can be: an illegal function code, an illegal data address code, an illegal data value code, a slave station equipment fault code and the like, wherein the illegal function code indicates that the function code in a received instruction data packet is an unidentifiable function code, the illegal data address code indicates that broadcast control instruction data of an undefined register in a protocol is contained in the received instruction data packet, the illegal data value code indicates that the received broadcast control instruction data cannot be identified, and the slave station equipment fault code indicates that equipment receiving the instruction data packet fails and the like.
The process of obtaining the broadcast control instruction data by the interface server according to the network protocol may be: the interface server writes the broadcast control instruction data into the corresponding storage location of a register, which is preconfigured according to the network protocol.
For example, for the command packet with the transaction identifier 0102, the interface server may read the header, the function code, and the broadcast control command data in the command packet, and determine that the header, the function code, and the broadcast control command data are all data conforming to the rules in the network protocol, then the broadcast control command data 00000000 00000001 may be written into the register No. 1, the broadcast control command data 00000101 00000011 may be written into the register No. 2, the broadcast control command data 00000000 00000010 may be written into the register No. 3, the broadcast control command data 00000000 00000001 may be written into the register No. 4, and the broadcast control command data 00000000 00000000 may be written into the register No. 5.
In this step, the interface server reads the broadcast control instruction data of the storage location corresponding to the register, calls the operation interface corresponding to the broadcast system according to the broadcast control instruction data, and transmits the broadcast control instruction data corresponding to the broadcast device included in the broadcast system through the operation interface.
For example, the interface server reads the broadcast control instruction data of the storage positions corresponding to the 5 registers, invokes the operation interface of the broadcasting device No. 1 corresponding to the broadcasting system, and sends the prerecorded broadcast content with the broadcast voice segment ID of 5 to the broadcasting device No. 1 in the broadcasting system through the operation interface, so that the broadcasting device No. 1 can broadcast the prerecorded broadcast content according to the broadcasting rule with the broadcasting priority of 3 and the repetition number of 2.
It should be noted that, in the embodiment of the present application, the broadcast system stores one or more prerecorded broadcast contents, and assigns a voice segment ID to each prerecorded broadcast content, and stores each prerecorded broadcast content and the voice segment ID in a prerecorded broadcast content table.
When the received instruction data comprises a certain voice segment ID, searching the prerecorded broadcast content corresponding to the voice segment ID in the prerecorded broadcast content table, and playing the prerecorded broadcast content.
