Embodiment 1

[0028] A smart home data acquisition system based on ZigBee, the water meter data acquisition system can realize the meter reading work of water meters in a residential area or even multiple residential areas. The water meter data acquisition system includes a water meter, a ZigBee wireless communication module, a ZigBee routing module, a ZigBee coordinator, a GPRS module and a central processing unit. This water meter is installed in the resident's family of community by water meter box body 7, namely every family one gas tank one water meter. Each water meter corresponds to a ZigBee wireless communication module or multiple water meters correspond to a ZigBee wireless communication module. Each ZigBee wireless communication module can be provided with a ZigBee routing module correspondingly or a plurality of ZigBee wireless communication modules can be provided with a ZigBee routing module correspondingly. Each ZigBee routing module can be provided with a corresponding ZigB...

Embodiment 2

[0034] On the basis of Embodiment 1, a ball head placement groove 59 is provided on the end surface of the plug assembly 53 close to the side of the water inlet channel 515, and a rubber ball head 52 is arranged in the ball head placement groove 59, and the rubber ball head 52 can rotate freely in the ball head placement groove 59; a fine-tuning spring 524 is also provided between the rubber ball head 52 and the bottom of the ball head placement groove 59, and the rubber ball head 52 can be adjusted according to the water inlet flow path The flatness and inclination of the end surface of the 515 end face are adaptively changed, so that the end face of the rubber ball head 52 is in full contact with the end face of the water inlet channel 515, and the sealing performance of the contact part is improved.

[0035] Preferably, a spherical water outlet 525 is provided at the end of the water inlet channel 515 close to the plug assembly 53 , and the radius of curvature of the spheric...

Embodiment 3

[0037] On the basis of Embodiment 1 or Embodiment 2, a damping hole 518 is provided inside the central core drainage hole 519, and the drainage aperture of the damping hole 518 is smaller than the aperture of the central core drainage hole 519, so the water pressure in the water inlet channel 515 is relatively high. hour, the water is discharged through the damping hole 518, and because the cross section of the damping hole 518 is smaller, the flow rate of the water discharged in the water inlet channel 515 is smaller, and the water pressure in the water inlet channel 515 increases faster, so it can Make the middle spool 58 and the outer spool 57 separate quickly at the discharge hole, improve and accelerate the pressure relief.

Abstract

The invention discloses a smart home data collecting system based on ZigBee, belongs to the technical field of smart homes, and aims at providing the smart home data collecting system with higher reliability and instantaneity. According to the technical scheme, the smart home data collecting system comprises a water meter, a ZigBee wireless communication module, a ZigBee routing module, a ZigBee coordinator, a GPRS module and a central processor. A water meter sensor in the water meter transmits water volume data information collected by the water meter sensor to the ZigBee coordinator through the ZigBee wireless communication module and the ZigBee routing module in sequence, and the ZigBee coordinator transmits the received water volume data information to the central processor through the GPRS module and a GPRS network. The smart home data collecting system is suitable for being used as a data collecting system in a smart home.

Description

technical field [0001] The invention belongs to the technical field of smart home, and relates to a water meter data acquisition system used in smart home, in particular to a ZigBee-based water meter data acquisition system used in smart home. Background technique [0002] With the development of modern technology, new requirements have been put forward for the meter reading method of water meters in smart homes, that is, water meters and meter reading methods of water meters are required to have higher reliability, real-time performance and data processing convenience in smart homes. , it is necessary to fundamentally solve the troubles caused by the existing household meter reading and charging to users and meter reading personnel, and improve the meter reading efficiency of water meters. [0003] In addition, water meters are a kind of measuring equipment for tap water, and they are generally used to measure the flow of water flowing through the water meter. The water in...
