Communication system for enabling low-power consumption alarm equipment to quickly access NB-IOT platform and method

Abstract

The invention relates to a communication system for enabling low-power consumption alarm equipment to quickly access an NB-IOT platform and method. The system comprises a smoke / temperature sensor detector, a manual alarm button and a sound-light alarm, wherein the smoke / temperature sensor detector can manually trigger the manual alarm button to send an alarm signal A; the alarm signal A is transmitted to the sound-light alarm in an LoRa wireless communication mode; the sound-light alarm sends sound and light warning signals and sends an alarm signal B at the same time; the alarm signal B can be transmitted to the NB-IOT platform at a COAP protocol through the NB-IOT module; and the NB-IOT platform finally transmits the alarm signal to a mobile phone APP client through the network. By adopting the above technical scheme, the time of alarm signal network access and transmission is greatly shortened, time is saved for person and property transfer in a fire area, and disaster avoidance anddisaster relief are more timely.

Description

technical field [0001] The invention relates to the field of fire alarm communication, in particular to a communication system and method for a low-power alarm device quickly accessing a NB-IOT platform. Background technique [0002] Existing fire alarm systems generally include smoke detectors, temperature detectors, fire alarm hosts, manual alarm buttons, sound and light alarms and other auxiliary equipment. When the smoke detectors or temperature detectors in the detection area detect When there is a fire, the alarm signal will be sent to the fire host. At the same time, if there is a fire in the early stage of the fire, you can press the manual alarm button in the nearby area. The manual alarm button will send the alarm signal to the fire host. The fire host judges that it is a fire. If an emergency occurs, the sound and light alarm equipment in the relevant area will be activated, and a strong sound and light alarm will be issued to remind the surrounding personnel to e...

Problems solved by technology

[0003] The inventor found that in the existing NB-IOT communication system, low-power devices such as smoke detectors, temperature detectors, and manual alarm buttons communicate with the server platform through NB-IOT communication. Both the temperature detector and the manual alarm button are powered by batteries. Usually, the device is in a low power consumption state, and the NB-IOT module is in a dormant or power-off state. When a fire alarm occurs, if a fire alarm signal is to be sent to the NB-IOT server platform, you must start the NB-IOT module first, and then establish a network connection with the system. It takes 3 to 5 minutes from the start of the module to the official connection to the network (the official time is considered normal), and the time for the device to connect to the network is too long. A delay of 3 minutes may cause irreparable major losses, delay the timing of the alarm, and will not have the early warning effect on the initial fire at all.
