[0018] The utility model provides a kind of embodiment, further illustrate the low-power bluetooth baby cushion alarm device described in the utility model.

[0019] As Figs. 1-3 As shown in a kind of low-power bluetooth baby cushion alarm device, including the film support plate 1 that can be arranged in cushion, cushion can be general child seat, film support plate 1 is equipped with control module 2, pressure sensing module 3, voltage boosting circuit module, power supply;The control module 2 is electrically connected with pressure sensing module 3, voltage boosting circuit module, power supply;The control module 2 is also connected with crystal. The control module 2 uses CMT4502.

[0020] The pressure sensing module 3 is equipped with multiple, the pressure sensing module 3 is thin film pressure sensor, 8 are used in the embodiment, are evenly distributed on the surface of film support plate 1;Pressure sensing module 3 is electrically connected between each other, the control module 2 is equipped with communication module 4, control module 2 is also connected with mobile alarm device and is matched, the mobile alarm device is equipped with communication module 4, buzzer 5 and vibration motor 6, battery, led lamp in.

[0021] Further, when being installed in child seat, insulating layer is also laid on film support plate 1.

[0022] Further, the communication module 4 is a Bluetooth 5.0 low-power Bluetooth chip.

[0023] When the baby is placed on the cushion, if the pressure sensing module 3 receives an activated baby with a weight of about 0.5GKG, it will send a BLE activation signal through the low-power Bluetooth chip of the control module 2, and the mobile alarm device will be activated after receiving the signal; after activation, if no BLE handshake is detected for 30 seconds, the buzzer 5 and the vibration motor will be activated every 3 seconds to remind the user, and the red light will flash twice for 3 seconds; the user can press the button for 1 second to cancel the alarm. If the BLE signal returns to the signal range, the mobile alarm device will automatically reactivate; the user can press the button at any time to check the system status. The color of the LED light can be set a. Green: BLE is connected with the baby on the cushion. b: Red: BLE is not connected or the baby is not on the cushion; the baby is picked up or leaves the cushion, if the pressure sensing module 3 does not detect the baby for 2 seconds, it will send a BLE signal through the communication module 4 of the control module 2 to deactivate the mobile alarm device. After the mobile alarm device is deactivated, the cushion enters standby state. If the BLE deactivation signal is received, the mobile alarm device stops the activated state. After stopping activation, it automatically enters standby state. When the battery is low, the mobile alarm device flashes twice every 60 seconds.

[0024] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
