Description

Technical Field

[0001] The present invention relates to the technical field of IP intercom, and in particular to a method for emergency calling in the case of network disconnection. Background Art

[0002] The most mature ward technology solution currently is the IP intercom solution. Whether it is a wired network, a wireless network, or an analog-to-digital solution, it all relies on the network. When the basic network infrastructure fails, the entire system will be paralyzed and calls will be unable to proceed normally. In hospital scenarios, this is a major hidden danger. Based on this, we have proposed a method for emergency calls in the event of a network outage. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention proposes a method for emergency calling in the event of a network outage.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A method for making an emergency call in a network disconnection situation, comprising the following steps:

[0006] S1: The device automatically detects available communication resources. When the device detects that there is no network, it automatically triggers the emergency call mode. The device sends a message to search for relay devices or base stations to scan for available relay devices or base stations nearby and initiates a connection request.

[0007] S2: The device uses a multimodal communication protocol adaptation algorithm to select the optimal communication protocol and optimal communication path to establish a stable connection with an available relay device or base station.

[0008] S3: The device is in a stable connection with the available relay device or base station in S2. When the device triggers a call, the device selects the corresponding communication protocol to send a call message;

[0009] S4: The call message is transmitted to the nurse station or management center through the relay device or base station;

[0010] S5: The nurse station or management center receives and processes the call information and goes to the ward to handle it.

[0011] Preferably, in said S1, the available communication resources detected by the device are preferably IP wired network communications.

[0012] Preferably, in S2, the multimodal communication protocol adaptation algorithm means that the device supports multiple communication protocols, the communication protocols include IP wired network, and IP wired network is preferred. When the IP wired network is abnormal and cannot be used, other communication protocols are switched. The selection of other communication protocols selects the optimal communication protocol and the optimal communication path based on performance indicators and application scenarios.

[0013] Preferably, the other communication protocols may be one or more of Bluetooth protocol, Zigbee protocol and LoRa protocol.

[0014] Preferably, in S2, the specific steps of selecting the optimal communication protocol are as follows:

[0015] S201: The device sends a search broadcast, and the base station or relay device responds after receiving the broadcast. The response information includes the unique identifier of the device and device parameters;

[0016] S202: The device receives the response information, sorts it in the order of receipt, and sorts and weights the response information according to the device parameter list to select the optimal communication solution.

[0017] Preferably, in S202, the equipment parameter list can be reorganized and redefined according to different project requirements, and the weights can be reallocated.

[0018] Compared with the existing technology, the present invention can make calls in a network-free environment and supports multiple communication protocols. In addition, it selects multiple communication protocols through a multimodal communication protocol adaptation algorithm, greatly improving the system's response speed and rescue rate. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] This embodiment provides a method for making an emergency call in the event of a network outage, including the following steps:

[0021] S1: The device automatically detects available communication resources, preferably IP wired network communication. When the device detects that there is no network, it automatically triggers the emergency call mode, sends a message to search for relay devices or base stations, scans for nearby available relay devices or base stations, and initiates a connection request.

[0022] S2: The device uses a multimodal communication protocol adaptation algorithm to select the optimal communication protocol and optimal communication path to establish a stable connection with an available relay device or base station.

[0023] The multimodal communication protocol adaptation algorithm means that the device supports multiple communication protocols, including IP wired network, with IP wired network as the first choice. When the IP wired network fails to function properly, it switches to other communication protocols, which can be one or more of Bluetooth, Zigbee, and LoRa. The selection of other communication protocols selects the optimal communication protocol and optimal communication path based on performance indicators and application scenarios.

[0024] S3: The device is in a stable connection with the available relay device or base station in S2. When the device triggers a call, the device selects the corresponding communication protocol to send a call message;

[0025] S4: The call message is transmitted to the nurse station or management center through the relay device or base station;

[0026] S5: The nurse station or management center receives and processes the call information and goes to the ward to handle it;

[0027] This embodiment can make calls in an environment without a network and supports multiple communication protocols. In addition, multiple communication protocols are selected through a multimodal communication protocol adaptation algorithm, which greatly improves the system's response speed and rescue rate.

[0028] In S2 of this embodiment, the specific steps of selecting the optimal communication protocol are as follows:

[0029] S201: The device sends a search broadcast, and the base station or relay device responds after receiving the broadcast. The response information includes the unique identifier of the device and device parameters;

[0030] S202: The device receives the response information, sorts it in the order of receipt, and sorts and weights the response information according to the device parameter list to select the optimal communication solution. The device parameter list can be reorganized and redefined according to different project requirements, and the weights can be reallocated.
