Synchronous alarm and reset method of the receiving end in the multi-send-one-receive Internet of Things

Abstract

The present invention proposes a synchronous alarm and reset method for the receiving end in the multi-send-one-receive Internet of Things. The method can simply set the on-site monitoring alarm to send alarm data in real time and send heartbeat data at regular intervals in the structure of the multi-send-one-receive Internet of Things. The synchronous alarm can reliably and synchronously alarm and synchronously reset. Even if there will be a small amount of data collision interference at the receiving end, and the large number of devices on the network and frequent heartbeats cause the remote synchronization alarm program execution to be interrupted frequently due to receiving new data, this method still ensures reliable synchronization of high real-time alarm states. Applying this method, the networking structure and data sending and receiving logic of the monitoring and alarming Internet of Things are simplified, and the sending and receiving logic of remote devices and field devices is easy to develop; The resource consumption of the in-device microprocessor that funnels received wireless data does not increase linearly.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method for synchronizing a remote synchronous alarm and a plurality of on-site monitoring alarms for synchronous alarming and automatic quick reset under the multi-send-one-receive star Internet of Things structure. Background technique [0002] In IoT applications that monitor temperature, smog, and gas concentrations and provide real-time alarms, a common technical solution is that multiple sensor devices installed on site can have their own warning signals such as sound and light alarms to remind nearby personnel of the alarm situation, and It can transmit the alarm information generated by its own sensor to the remote synchronous alarm installed in the duty room, monitoring room, etc. through wireless communication. According to the received alarm information, the remote synchronous alarm activates the sound and light alarm device of the device, thus prompting the near...

Problems solved by technology

In particular, the number of LAN devices is high, and when using spread spectrum communication technology with low airspeed such as Lora, the multi-send-one-receive network adopts polling or time-sliced ​​networking, and the delay is more prominent, making the on-site and remote The device is visibly out of sync

The above synchronization problems lead to complex networking and data reporting logic, high difficulty in development, and the time delay of remote alarm and reset may be large, and it is difficult to guarantee the real-time performance of alarm and reset, which will hinder low-cost and high-reliability multiple The engineering application of a simple Internet of things alarm system
