Referring to fig. 1, a schematic structural diagram of a smoke sensing device provided in an embodiment of the present application is shown in fig. 1, where the smoke sensing device includes a smoke sensing module 110, a wireless access module 120, and an external power supply module 130; the wireless access point module 130 is connected with a wired network; wherein:
an external power supply module 130, configured to supply power to the smoke sensing module 110 and the wireless access point module 120;
a wireless access point module 120 for providing wireless access;
and the smoke sensing module 110 is configured to perform smoke detection and upload alarm information through a wired network connected to the wireless access point module 120 when it is determined that an alarm condition is met.
In the embodiment of the application, the influence on the attractiveness of the use environment is considered when the independent smoke sensor and the wireless access point are separately installed and deployed.
In addition, the smoke sensing equipment is short in service life cycle when powered by a battery, high in maintenance and management difficulty, and easy to report alarm information due to unsatisfactory signals when reporting the alarm information through a wireless network.
Therefore, by the integrated deployment of the smoke sensing module and the wireless access point module, under the condition that the smoke sensing function and the wireless access function are ensured (the terminal equipment with the wireless internet access function can access the wireless network through the wireless access point module 120 of the smoke sensing equipment, and further network access is realized), the positions occupied by the installation and deployment of the smoke sensing equipment and the wireless access point are reduced.
In addition, the smoke sensing module and the wireless access point module are powered through the external power supply module, frequent replacement of a battery is avoided, the service life cycle of smoke sensing equipment is prolonged, and the maintenance and management difficulty is simplified.
The smoke sensing module reports alarm information through a wired network connected with the wireless access point module, for example, when the smoke sensing module detects that smoke meets an alarm condition, the smoke sensing module sends the alarm information to the wireless access point module, and the wireless access point module reports the alarm information through the wired network connected with the smoke sensing module, so that the stability and reliability of uploading the alarm information are improved.
It should be noted that, in the embodiment of the present application, when the smoke sensing module determines that the alarm condition is met, the alarm information may be reported according to the above method, and in addition, the alarm may be given in an acoustic/optical alarm manner.
For example, a buzzer may be built in the smoke sensing device, and when the smoke sensing module 110 determines that the alarm condition is satisfied, the buzzer may make a strong sound to implement local alarm.
In an example, the external Power supply module 130 may supply Power to the smoke sensing module 110 and the wireless access point module 120 through a direct current voltage stabilization Power supply manner or a POE (Power Over Ethernet) Power supply manner.
In one possible embodiment, as shown in fig. 2, the smoke sensing apparatus may further include a standby network module 140; wherein:
the smoke sensing module 110 is further configured to upload alarm information through a network provided by the standby network module when it is determined that the alarm condition is met and the wired network connected to the wireless access point module 120 is abnormal.
Illustratively, in order to further improve the stability and reliability of the alarm information reporting and avoid that the alarm information cannot be reported due to an abnormal wired network connected to the wireless access point module 120, a standby network module 140 may be further deployed in the smoke detector.
In one example, the standby network module 140 may be a telecommunications carrier communication module, such as an NB-IOT (Narrow Band Internet of Things) module, a 2G module, a 3G module, a 4G module, or a 5G module, etc.
For example, when the smoke sensing module 110 determines that the alarm condition is satisfied and the wired network connected to the wireless access point module 120 is abnormal, the smoke sensing module 110 may upload the alarm information through the network provided by the standby network module 140.
For example, the network provided by the standby network module 140 may include an NB-IOT network, a 2G network, a 3G network, a 4G network, or a 5G network, among others.
Illustratively, the standby network module 140 may be powered by an external power module.

and the standby power supply module 150 is used for supplying power to the smoke sensing module 110 when the external power supply module 130 is powered off.
Illustratively, in order to improve the operation stability of the smoke sensing module 110 and avoid the smoke sensing module 110 from being unable to operate due to the power failure of the external power supply module 130, a standby power supply module 150 may be further disposed in the smoke sensing device.
Illustratively, the backup power module 150 is a backup battery.
When the external power module 130 is powered off, the smoke sensing device can supply power to the smoke sensing module 110 through the standby power module 150 to ensure that the smoke sensing module 110 can continue to work.
It should be noted that, considering that the wired network connected to the wireless access point module 120 is also usually abnormal when the external power supply module 130 is powered off, when the smoke sensor device is deployed with a standby network module (for example, the standby network module 140 in the smoke sensor device shown in fig. 2), the standby power supply module 150 may also supply power to the standby network module when the external power supply module 130 is powered off, so as to ensure that the smoke sensor module 110 can still report alarm information when the external power supply module 130 is powered off.
In a possible embodiment, the smoke sensing module 110 may be further configured to report the device operating status through a wired network connected to the wireless access point module 120.
For example, in order to enable the management end to remotely know the working state of the smoke sensing device, the smoke sensing module 110 may report the working state through a wired network connected to the wireless access point module 120, that is, whether the smoke sensing module 110 is in a normal working state.
For example, the smoke sensing module 110 may periodically (the period duration may be set according to actual requirements) report the operating state through a wired network connected to the wireless access point module 120.
For example, reporting the working state of the smoke sensor module 110 may be implemented by sending a heartbeat message, and when the management end device receives the heartbeat message sent by the smoke sensor module 110, it may be determined that the smoke sensor module 110 is in a normal working state; when the management-side device does not receive the heartbeat messages sent by the smoke sensing module 110 within a period of a continuous preset number, it may be determined that the smoke sensing module 110 is abnormal.
It should be noted that, in this embodiment of the application, when a standby network module (for example, the standby network module 140 in the smoke sensing apparatus shown in fig. 2) and a standby power supply module (for example, the standby power supply module 150 in the smoke sensing apparatus shown in fig. 3) are deployed in the smoke sensing apparatus, when a wired network connected to the wireless access point module 120 is abnormal, the smoke sensing apparatus may be switched to use the standby power supply module and the standby network module, and the smoke sensing module 110 may report the operating state of the apparatus through a network provided by the standby network module.
