In gateway communication, we usually encounter these situations: the gateway is offline, the upper limit is exceeded, the upper limit is higher, the lower limit is exceeded, the lower limit is exceeded, 0-1 displacement alarm, and 1-0 displacement alarm. This is basically the most common type of alarm in gateway communication. So how to realize the real-time alarm reminder (pop-up window, SMS, sound), historical alarm query and other functions under the technical selection of the front-end vue+back-end java mode?
There is no doubt that we are doing global real-time alarm processing.
