Wireless spread spectrum smart household measuring meter, remote gas meter system and control method

Abstract

The invention relates to a wireless spread spectrum intelligent household meter, a remote gas meter system and a control method. The household meter includes a power supply, a controller, a storage module and a wireless spread spectrum module. The controller is connected with the storage module and the wireless spread spectrum module respectively, and the meter measurement data in the storage module is sent out through the wireless spread spectrum module; it also includes a timer, and the timing output of the timer is connected with the controller and the wireless spread spectrum module respectively. The state control terminal of the spread spectrum module is connected to make the controller and the wireless spread spectrum module sleep and wake up synchronously. The invention adopts the wireless spread spectrum module, the signal transmission distance is long, the anti-interference ability is strong, the bit error rate is low, and the problem of difficulty exceeding the standard is solved; the timer is used to make the controller and the wireless spread spectrum module wake up at a certain frequency, It saves energy, improves the service life of the power supply, improves the reliability of the networking, and ensures the reliable and efficient operation of the network.

Description

Technical field [0001] The invention relates to the field of metering instruments, in particular to a wireless spread spectrum intelligent household metering instrument, a remote gas meter system and a control method. Background technique [0002] So far, the "wireless remote meter" existing on the market mainly uses traditional FSK modulated radio frequency modules, which have a weak radio wave diffraction ability. Due to the different user room types, the structure, height, and even furniture and kitchen utensils are different, and the shielding effect inside the kitchen is more obvious, resulting in a more complicated application environment for radio frequency communication. The number of effective transmission floors is generally less than 3 floors. Even if the FSK modulated wireless network adopts a meter-by-meter relay communication protocol, due to its micro power (less than 50mw) and short distance (less than 3 floors), plus factors such as weather, temperature, There a...
