The invention relates to the technical field of Internet of Things communication, discloses an Internet of Things multi-Android client state synchronization method, and solves the problems of poor state consistency, high back-end dependence, large delay and insufficient compatibility in the prior art. According to the scheme, the method comprises the steps that after a client completes initialization, MQTT connection with a rear end is established, an MQTT state message pushed by the rear end is monitored, after the message is received, equipment state information is obtained through analysis, local state cache and a UI interface are updated, meanwhile, the client serves as a distribution node, a UDP synchronization message containing the equipment state and the IP of the distribution node is established, and the UDP synchronization message is sent to the client. The UDP synchronization message is broadcasted to the local area network, other clients in the local area network receive the UDP synchronization message and then verify whether the distribution node IP is the client in the local area network, if the verification is passed, the message is analyzed, the state updating timestamp and the local cache timestamp are compared, and the local state cache and the UI interface are updated only when the state updating timestamp is larger.

The utility model relates to a hearing aid technical field, concretely relates to an ear hanging type hearing aid, include: a main part assembly for wearing at the head or neck of user, its end part setting has the host unit of built -in talk microphone, two ear hanging assemblies are connected to both ends of main part assembly respectively, and the ear hanging assembly is flexible arc structure, is used for around setting at the ear of user, two connecting assemblies are connected to an ear hanging assembly respectively, and at least one connecting assembly is equipped with hearing aid microphone, two receivers are connected to a connecting assembly respectively, and the receiver assembly is equipped with the ear -entering part to be used for putting into the ear canal of user. The ear hanging assembly is around setting on the ear, and the ear -entering part of receiver assembly cooperates to make the connecting assembly stably wear at the front side of ear of user, and hearing aid microphone can reliably receive the sound of the front and both sides of user, can also avoid the noise brought by the shaking or the friction, help the hearing aid accurate reception of external sound, improve the hearing aid effect.

This application relates to an end cap and a clothes drying rack, including: an end cap body and a microphone mounting base disposed on the end cap body, wherein: the microphone mounting base is used to fix the microphone on the end cap body, and the microphone's pickup end faces the outside of the end cap body. By disposing the microphone mounting base on the end cap body and making the microphone's pickup end face the outside of the end cap body, this application satisfies the need to acquire the user's voice information through the microphone while avoiding potential microphone obstruction in different usage states of the clothes drying rack. This effectively ensures that the microphone can stably and reliably receive the corresponding voice information in all states of the clothes drying rack, effectively improving the clothes drying rack's response to the user's voice control commands and enhancing the user experience.

The utility model discloses a motorcycle steering lamp structure, including the lamp shell and the lamp pearl, the inside of lamp shell is provided with the circuit board, and the top of lamp shell is provided with the lamp shade, the surface of circuit board is provided with the lamp pearl, and one side of lamp shell is provided with the steering pole, the utility model discloses a double fixed structure through bolt and elastic buckle, has realized the firm connection of lamp shade and lamp shell, has guaranteed the stability of steering lamp under complex road condition, and the lamp shade and lamp shell installation disassembly are more convenient further, through the cooperation of the plug -in pole in lamp shell and the plug -in barrel on the circuit board, make the circuit board can accurate installation in lamp shell, has guaranteed the stability of circuit connection, through the reflection of the light -reflecting part can effectively reflect the ambient light, even if the steering lamp is not opened, also can through the reflection car headlamp, street lamp etc. Light, make the motorcycle contour more clear, remind other road user's attention, through the good refraction and dispersion effect of arc lamp shade to light, has improved the visibility of the steering signal significantly.

The invention discloses a ring main unit storage battery online health management device and method, and belongs to the technical field of ring main unit storage battery health management, and the device comprises a power supply module, a sensor module, an edge calculation module, a man-machine interface module, a communication module and an execution mechanism.
