Description

Technical Field

[0001] This invention relates to the field of smoke alarm technology, and in particular to a floor smoke alarm system with wireless communication function. Background Technology

[0002] With the development of modern building and electrical technologies, modern buildings contain a large number of electrical devices, and the large number of residents makes their internal environments complex. To ensure the safety of buildings and their occupants, smoke detectors are typically installed on each floor to trigger an alarm when smoke is detected, preventing fires from going undetected and causing loss of life and property. However, current smoke alarm systems have a fixed sensitivity and cannot adjust in real time based on external environmental factors, making them prone to false alarms. For example, smoke from someone smoking might trigger an alarm; children might intentionally create smoke around the sensor, triggering an alarm; or objects that produce smoke might be left unattended and trigger an alarm. This not only causes panic among other people but also misleads safety personnel and wastes social resources. Summary of the Invention

[0003] The purpose of this invention is to address the problem that current smoke alarm systems cannot adjust their sensitivity in real time according to external environmental factors, which easily leads to false alarms. Therefore, this invention proposes a floor smoke alarm system with wireless communication capabilities.

[0027]

[0028] Where LMD is the sensitivity adjustment value, T is the real-time temperature data, ht is the real-time humidity data, N is the building's service life data, H is the number of households on the current floor, and D is the number of households on the current floor. i The electricity load for each household is i.

[0032] Alarm information forwarding module: Used to forward alarm information to the property management platform module to realize alarm operation.

[0033] Furthermore, the process by which the determining module determines whether a fire has occurred at the location of the smoke and temperature sensor is as follows: When the smoke and temperature sensor module senses smoke with temperature, it collects smoke concentration and smoke temperature data per second over a period of time. If:

[0034]

[0035] If the smoke and temperature sensing module is located at the same location, a fire is determined to have occurred; otherwise, no fire is determined to have occurred at the same location. Wherein, YN s YT s These represent the smoke concentration and temperature data per second (s), respectively, where t is the total time and Z is the preset threshold data.

[0036] Furthermore, after receiving the alarm information, the property management platform continues to collect smoke concentration and smoke temperature data every minute for a period of time. If:

[0037]

[0038] The property management platform sends an alarm signal to the fire protection platform, which then sends an alarm to the nearest fire station. Conversely, if the signal is not received from the fire protection platform, no alarm is sent. (YN) m YT m The data are smoke concentration and temperature per minute (m), t1 is the total time, and Z1 is another preset threshold data.

[0043] S r = (YN + YT) × μ

[0044] Among them, S r YN and YT represent the smoke concentration and temperature data at the production site, respectively, and μ is the dispatch coefficient: 0.05-0.1.

[0045] Then, randomly select the number of personnel to be dispatched from the property management staff closest to the incident point:

[0046] B = (L / random) → S r random∈(0,L]

[0047] Where B is the sorting number, L is the total number of property management personnel closest to the occurrence point, and random is a random number, "→S r Run S for the formula "B = (L / random)". r Second-rate.

[0048] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0049] This invention can collect external factors at the location where the smoke and temperature sensing module is located in real time, and adjust the sensitivity of the smoke detection system accordingly. Furthermore, upon detecting smoke accompanied by temperature, it does not immediately trigger an alarm; it waits for confirmation before triggering the alarm. Compared to current smoke alarm systems, this system greatly reduces the likelihood of false alarms, preventing panic and misleading safety personnel. Additionally, after confirming a fire at the location of the smoke and temperature sensing module, several property management personnel will be dispatched to handle the situation, avoiding both insufficient manpower and wasted resources. During the dispatch, the fire situation will continue to be monitored, and if the monitoring personnel are unable to handle the fire, the nearest fire station will be automatically alerted.
