Problems solved by technology

[0003] The existing air defense and disaster prevention alarm equipment covers the city with sound through loudspeaker equipment. Since the information that can be conveyed by sound is simple and single, when an air raid or disaster occurs, the notification effect of the air defense and disaster prevention alarm is poor.

Embodiment 1

[0056] figure 2 A schematic flow diagram of a method for broadcasting an air defense and disaster prevention warning provided in Embodiment 1 of the present application, as shown in figure 2 As shown, this embodiment mainly includes:

[0057] S201: Receive the disaster prevention information data sent by the air defense and disaster prevention server, and perform content verification on the disaster prevention information data according to the calculated first content check code.

[0058] here, as image 3As shown, the air defense and disaster prevention server may include at least one of an air defense and disaster prevention alarm distribution system, a smart civil air defense multimedia education release system, a multimedia release, a digital (smart) civil defense system, and a civil defense ground network integrated information system. In times of disaster and war, civilian networks are usually unreliable, and it is necessary to broadcast air defense and disaster prev...

Embodiment 2

[0072] Existing Bluetooth devices usually need to establish a pairing connection before data communication can be carried out, which cannot meet the timeliness requirements of air defense and disaster prevention alarms, and the two-way communication can be carried out between the sending end and the receiving end of air defense and disaster prevention alarms by establishing a pairing connection. Therefore, using Bluetooth name data and / or Bluetooth broadcast data to send air defense and disaster prevention alarms can avoid the above problems. Embodiment 2 of the present application provides a method for air defense and disaster prevention alarm broadcasting using Bluetooth name data.

[0073] Such as Figure 4 As shown, embodiment two of the present application provides the broadcasting method of air defense and disaster prevention warning, including:

[0074] S401: Receive the disaster prevention information data sent by the air defense and disaster prevention server, and pe...

Embodiment 3

[0082] Embodiment 3 of the present application provides a method for broadcasting air defense and disaster prevention alarms by using Bluetooth broadcast data. Such as Figure 5 As shown, embodiment three of the present application provides the broadcasting method of air defense and disaster prevention warning, including:

[0083] S501: Receive the disaster prevention information data sent by the air defense and disaster prevention server, and perform content verification on the disaster prevention information data; when the content verification of the disaster prevention information data is correct, encrypt the disaster prevention information data.

[0084] S502: Divide the encrypted disaster prevention information data into at least one data frame; wherein, each data frame contains at most a preset number of bytes.

[0085] In order to ensure that each data frame can be completely received, frame number, frame end identifier and byte quantity information are added to each d...

Abstract

The invention discloses a broadcasting method and device of air defense and disaster prevention alarm, an electronic device and a storage medium, and relates to the air defense and disaster preventionalarm technology. The method comprises the following steps: receiving disaster prevention information data sent by an air defense and disaster prevention server, and carrying out content verificationon the disaster prevention information data according to a first content check code obtained through calculation; when the content of the disaster prevention information data is verified to be correct, encrypting the disaster prevention information data; generating Bluetooth data according to the encrypted disaster prevention information data; and respectively sending the Bluetooth signals carrying the Bluetooth data at high power and low power, and repeatedly and circularly executing the step of respectively sending the Bluetooth signals carrying the Bluetooth data at high power and low power until a preset stop condition is met. According to the method, disaster prevention information data are transmitted through a digital method, and the notification effect of air defense and disasterprevention alarm is greatly improved.

Description

technical field [0001] The present application relates to air defense and disaster prevention alarm technology, in particular to a method, device, electronic equipment and storage medium for air defense and disaster prevention alarm broadcasting. Background technique [0002] Air defense and disaster prevention alarm equipment is an important part of urban air defense and disaster prevention projects. It is usually used for disaster forecast and emergency notification in disaster relief and emergency situations, and it is used for civil air defense in wartime. It is the people's government at all levels to implement civil air defense. The basic means of commanding and organizing personnel evacuation. [0003] The existing air defense and disaster prevention alarm equipment covers the city with sound through loudspeaker equipment. Since the information that sound can convey is simple and single, when an air raid or disaster occurs, the notification effect of the air defense a...
