Embodiment 1

[0033] This embodiment provides a broadcast message transmission method, first combined before the method will be described. figure 1 A broadcast system consisting of the loss device involved in the method will be described. figure 1 A positional relationship of the loss device X, relay device A, relay device B, and receiving device O may be presented, wherein figure 1 Turning in the periphery of the middle device is used to represent the coverage of the device signal, based on figure 1 The process of retrieving the lost device X is retrieved by the loss device X, relay device A, relay device B, and receiving device O can include: relay device A receives the broadcast information of the lost device X, forwarding, The relay device B receives the broadcast information forwarded by the relay device A, then forwards, the receiving device O receives the broadcast information forwarded by the relay device B, and the receiving device O finds the position of the lost device X. It should b...

Embodiment 2

[0051] This embodiment provides another broadcast message transmission method, which is implemented by a relay device, and the relay device can be used to receive the broadcast message of the lost device, and broadcast the received broadcast message to expand the loss of equipment. Signal coverage, Figure 4 It is a flow chart of this method, such as Figure 4 As shown, the method includes:

[0052] Step 401: Receive broadcast messages;

[0053] In step 401, the acquired broadcast signal may be issued by the lost device, in which case, the received broadcast message includes the location information of the lost device.

[0054] Step 402: Save in the third preset cycle, determine the third broadcast frequency;

[0055] Step 403: Broadcasting the broadcast signal that is broadcast in the third broadcast frequency point.

[0056] In the present embodiment, after receiving the broadcast message, the broadcast message can be directly determined, and the broadcast message is received, and...

Embodiment 3

[0061] This embodiment provides a broadcast message transmitting apparatus for implementing a broadcast message transmission method provided by the first embodiment. Figure 5 Is a block diagram of the device, such as Figure 5 As shown, the device 50 includes:

[0062] The first determination module 51 is configured to scan in the first preset cycle while determining the operating state abnormality of the device to determine the first broadcast frequency point;

[0063] Get module 52 for acquiring location information of the device;

[0064] The first broadcast module 53 is used to use the location information of the first broadcast frequency broadcast device;

[0065] The second determination module 54 is configured to increase the preset cycle to the second preset period in the case where the broadcast message containing the device location information is swept in the second preset cycle to determine the second broadcast frequency. point;

[0066] The second broadcast module 55 i...

Abstract

The purpose of the present disclosure is to provide a broadcast message sending method, device, storage medium, device and broadcast system to solve the problem of difficulty in obtaining location information of lost devices in related technologies. The disclosed broadcast message sending method includes: in the case of judging that the working state of the device is abnormal, performing frequency scanning in a first preset period to determine the first broadcast frequency point; obtaining the location information of the device; using the first broadcast frequency point to broadcast the device location information; in the case of obtaining a broadcast message containing device location information, increase the preset period to the second preset period, and perform frequency scanning with the second preset period to determine the second broadcast frequency point; When the second preset period is reached, the location information of the device is broadcast at the second broadcast frequency. The present disclosure improves the probability of finding the lost device on the basis of reducing the energy consumption of the lost device.

Description

Technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a broadcast message transmission method, device, storage medium, device, and broadcast system. Background technique [0002] Currently, unmanned aircraft, no car and other equipment, often occur due to equipment failure, interference, collision, etc., causing the equipment to lose control and loss. In order to retrieve the lost device, you need to position the lost device, but is limited by the lost device itself, and the communication function is limited. If the lost device is far away, the positioning information of the lost device is more difficult. It is possible to search in a larger range, for example, a communication network may need to be temporarily formed, and a large number of human resources can be searched. Inventive content [0003] It is an object of the present disclosure to provide a broadcast message transmission method, device, storage medium...
