Embodiment 1
[0041] Such as figure 1 As shown, the embodiment of the present invention provides an intelligent control system for a guest room, and the system includes a Doppler sensor, a filter amplifier module, a control module, and a power control module.
[0042] The Doppler sensor is installed on the roof of the guest room, and is used to transmit microwave signals to the human body and receive feedback signals from the human body.
[0043] In order to achieve the above functions, the Doppler sensor is the 24GHz microwave Doppler sensor NJR4262 produced by Japan's New Japan Radio Co., Ltd., which outputs two signals through quadrature detection: I signal and Q signal.
[0044] It should be noted that in the sensor device, every time a sensor is added, the detection range will be expanded and the function will be increased. Install the connector for adding sensors to achieve the best results. For example, the detection of the presence of all living organisms in the house and the vital...
Embodiment 2
[0070] Such as image 3 As shown, on the basis of Embodiment 1, a communication module and an alarm module are added.
[0071] The communication module provides a wired LAN interface or a wireless communication module to realize the communication between the control module and the front desk of the hotel or hotel.
[0072] Wired LAN is a wired LAN plug-in IC conforming to IEEE.802, and the EthernetConnector TM11RD with a built-in pulse transformer performs input and output to the 3-wire serial communication of the CPU.
[0073] In order to prevent the wired LAN from generating noise, line filters DLW 2 1 S900 are respectively inserted in TX and RX. And when used in hospitals and other occasions, in order to avoid affecting the use of medical equipment, an EMS filter BLM31PG330 is inserted into the ground line.
[0074] The wireless communication module can choose 120A connector, and the 120A connector is loaded with the Wifi plug-in (ESP8266) circulating in the market, and a...
Embodiment 3
[0091] Such as Figure 4 As shown, on the basis of Embodiment 2, input and output interfaces are provided for connecting external devices and realizing data interaction with external devices.
[0092] The input contact is to use the J20 connector to connect the switch and relay of the non-voltage a contact outside the circuit board. Not only that, but in practical applications, a diode can be inserted externally to protect it when the external 5V is wrongly connected.
[0093] The output contact is a non-voltage a contact, and it is output externally through the J5 connector. Assuming that the external output of display lamps, doorbells, internal communication equipment, etc. (AC or DC up to 24V 100mA), photorelays can be used correspondingly.
