The control mode is as follows: the control mode of the master station comprises unified control (alarm is uniformly distributed to all alarms in the whole city), regional control (alarm is distributed to all the alarms in a certain prefecture county), city group control (partial alarms are selected in the city to form a predetermined plan group, and all the alarms in the predetermined plan group are distributed), district group control (partial alarms are selected in the prefecture county to form a predetermined plan group, and all the alarms in the predetermined plan group are distributed), and single control (one or a small number of distributed alarms are independently selected).

Alarm issuing: the issuing of the alarm comprises air defense alarm (advance, air attack and relief), disaster alarm, remote power on and off, intelligent voice, control mode and alarm type which are respectively combined into different communication instructions to form issuing data stream for issuing.

And (3) state query: all the state queries are issued in a system control mode, all the devices are returned in a unified mode, the main control end records the operated device list before issuing, the devices in the operation list make return response, and other devices only update the device states.

Heartbeat monitoring: and the heartbeat monitoring is also completely distributed in a system control mode, and the returned result updates the equipment state and presents the state to the user operation interface in real time.

Communication maintenance pipe: communication maintenance generally refers to operations of configuring base station and alarm communication network parameters, updating keys and configuring channels.

FIG. 9 is a diagram illustrating an information interaction method according to the present invention. As shown in fig. 9, alert and intelligent voice delivery: the alarm and the intelligent voice issuing instruction are directly issued to the base station through the master station, the base station forwards the alarm and the intelligent voice issuing instruction, generally, under the condition of no interference, the alarm can receive the alarm and the intelligent voice issuing instruction by 100%, and after the instruction is received, the alarm can be sounded normally, so that the sounding rate of the alarm can be ensured to be 100%. Whether an alarm rings normally or not is judged, the master station actively sends a state query instruction to acquire a ring state, and after the alarm issuing instruction is sent, the state query instruction is directly sent to acquire the alarm ring state. This approach is more suitable for the current construction situation of civil air defense alarms. Meanwhile, the state query instruction is accompanied by other parameters of the alarm, and the heartbeat state is copied.

Status accompanied by heartbeat query: the main control end automatically detects that the idle communication time (the idle communication time: the system does not have any data transmission and reception, and the timing is started from the last transmission or reception) exceeds 5 minutes, then a heartbeat inquiry is initiated, the heartbeat inquiry feeds back whether the alarm is on line and the state of the equipment currently, and meanwhile, the channel communication effect is automatically analyzed according to the feedback condition, so that the optimal channel is intelligently judged and selected for issuing operation.

And (3) reporting abnormal state or check-in: when the alarm equipment generates an abnormal condition, the alarm equipment actively reports, the reporting mode is the same as the return mode, and the function can be configured in a background to determine whether to start or not in order to ensure the normal operation of alarm distribution; similarly, a sign-in button is arranged on the alarm panel, and when the active state reporting mode is the opening mode, the sign-in information can be actively reported to the server.

Communication maintenance pipe: the communication maintenance management mainly realizes that configuration parameters are issued to the alarm at a main control end, the alarm receives the configuration information and then returns the configuration information to the main control end to prompt the success of configuration, and meanwhile, a configuration parameter query function is provided, and the main control end can query the configuration parameters of the alarm at any time.

Real-time online: the alarm communication realizes real-time online of civil air defense alarm through data transfer radio communication, can directly check whether equipment is normally servo or not, provides decision basis for judging whether the alarm can be sounded in real time or not, and can prove that at least one path of frequency points used by the current equipment is normal and interference does not exist as long as the equipment is normally online, so that the alarm and intelligent voice broadcast can be safely and normally provided, when the equipment is disconnected, a system gives an alarm, and provides an auxiliary means for ordinary operation and maintenance of the civil air defense alarm.

Further explanation is provided for the presentation of the present application:

the alarm can automatically select a communication optimal channel from three channels F4, F5 and F6 according to the heartbeat inquiry communication effect through a data transmission radio station, F4, F5 and F6 are a plurality of alarm return channels preset by the alarm, the optimal channel can be understood as a target alarm return channel, and if the return is needed, a frequency locking instruction is sent from the target alarm return channel, and a set period or times are continuously sent; the base station receiving end digital radio station will poll the switching channel all the time, once receiving the frequency locking command sent by the alarm end digital radio station, will stop polling the switching channel, lock in the channel receiving the frequency locking command, wait for the data transmission of the alarm end data string radio station; if the data is received, after the data is received and the function operation is analyzed and executed, continuously polling the switching channel; if no data is received for more than 3 seconds, the switching channel is continuously polled.

Or the three channels of F4, F5 and F6 of the alarm data transmission station all transmit data, and the channel F4 is locked firstly to transmit the data; then locking the F5 channel to send data; the F6 channel is locked again and data is transmitted. The three channels are ensured to send the same issuing command data, and after the data transmission station of the base station receives the data of the F4 channel, if the data can be analyzed normally and executed directly, the data received by the subsequent two channels are automatically ignored, and similarly, the F5 receives the normal command and the F6 receives the neglect.

Fig. 10 is a schematic diagram of the operational flow 100 of the present invention. As shown in fig. 10, before the device online condition of the existing alarm is confirmed, each alarm point is respectively started to test for machine before the alarm is issued, then the main controller detects, sends a silent test tone instruction, receives a response indicating that the representative device is online, does not receive that the representative is not online, and then issues the alarm to the online device, and the offline device has a local key of the alarm point personnel to issue the alarm. This approach does not guarantee a 100% ring of alarms, exposing the failure of the faulty device to the immediate prior to the alarm being issued. For equipment which cannot be repaired in a short period, alarm issuing of the alarm point can only be abandoned, and if the equipment is in wartime and disaster, the risk is quite high, alarm coverage of partial areas can be omitted, and unnecessary life and property loss is caused.

FIG. 11 is a schematic diagram of the operation 200 of the present invention. As shown in fig. 11, in the present technology, when the idle communication time is longer than 5 minutes, a heartbeat query is initiated, status queries are performed on all alarms in the urban area, and if the status queries can be returned normally, the device is identified to be online, and the device status is recorded. If the equipment is not shown again for 5 times continuously, the equipment is marked to be offline, and an alarm is given to prompt a relevant person in charge of the communication station, so that the communication station immediately sends a technician for troubleshooting and maintenance, and the maintenance technician is urged to recover the normal operation of the equipment as soon as possible. Thus, the equipment failure is eliminated in normal times. When the alarm issuing requirement exists, the alarm or the intelligent voice is remotely issued through multiple channels and multiple hands of the master control, so that each alarm can be ensured to sound normally, the coverage of the alarm is 100 percent, and each person in a city is not abandoned in disaster and wartime.

The real-time online technology enables the alarm to form a closed loop in operation and maintenance at ordinary times, immediately checks and solves problems when the problems are found, enables the whole set of emergency response alarm system to be in a standby state at any time, and enables the alarm system to really serve in disaster time and wartime.

And (3) reporting the state:
