The invention discloses a wireless monitoring device for infant apnea, which comprises a respiratory signal detection module for emitting microwave signals to detect infant respiratory conditions, an apnea detection module for comparing detected respiratory signals and converting frequency and a sound and light alarm module for comparing with a preset threshold and triggering an alarm. The wireless monitoring device for infant apnea wirelessly detects infant respiratory signals and then converts the signals to respiratory frequency signals and voltage signals. After the signals are compared with the preset threshold, when frequency is found to be too low so that apnea is caused, the alarm signals are triggered. By means of the sound and light alarm, guardians are informed and correct sleep positions of infants timely or do other treatments to ensure normal respiration of the infants.

The invention discloses a device for controlling the temperature of a large-space building. The device comprises an air supply man pipe, a system controller, a wireless temperature receiver and a wireless infrared counting receiver. The system controller is connected with the wireless temperature receiver and the wireless infrared counting receiver. A wireless temperature sensor and a wireless infrared counter are arranged in large space. The system controller is connected with the valve controller of the air supply main pipe. The wireless temperature receiver is in wireless connection with the wireless temperature sensor. The wireless infrared counting receiver is in wireless connection with the wireless infrared counter. The invention further discloses a method for controlling the temperature of the large-space building. The method comprises the first step that the device is started, the second step that the wireless infrared counter measures the number of seated people, the third step that when the seated rate is low, the valve controller closes a volume damper, and the fourth step that when the seated rate is high, the system controller adjusts the air volume of an air inlet. The device and method are reasonable in design and standard in process, achieve the horizontal temperature control over the large-space building and can be widely applied to various public buildings.

The present invention provides an online monitoring system for street lamps of the Internet of Things, including a lamp post, a wireless receiving monitoring cabinet structure, a street lamp monitoring box structure, a brightness monitoring lamp head structure, an online monitoring display cabinet structure, a remote display screen structure, a fixing seat, and a light pole. Camera, computer, monitoring platform, supporting legs, stable seat and data line, the lamppost bolts are connected to the middle of the upper surface of the fixed seat; the wireless receiving monitoring cabinet structure is connected to the left side of the lower surface of the monitoring platform by screws Position; the structural screw of the street lamp monitoring box is connected to the inner lower side of the lamp post. The setting of the wire harness frame of the present invention is beneficial to restrain the monitoring connecting wires and maintain a good monitoring environment; the wireless signal transceiver is electrically connected to the wireless router, which is conducive to realizing wireless monitoring of street lamps and improving monitoring efficiency; vertical partitions and The setting of the transverse partition is beneficial to divide the ventilation monitoring box into different spaces, and it is convenient to install multiple monitoring display screens.
