Wireless intelligent weighing sensor system

Abstract

The invention discloses a wireless intelligent weighing sensor system. The system comprises a cloud server, a wireless access part, a weighing sensor module, a controller module, an LED screen, an A / Dconverter, a serial port and an intelligent weighing device. The system is connected with the wireless module through a standard interface, and after the configuration succeeds, a transparent transmission mode is started to transmit data; the weighing sensor amplifies a circuit signal to the controller after sensing through a strain gauge core to realize two-way transmission with the LED screen;then the signal is transmitted to the A / D converter, and the A / D converter selects the double-speed gain after receiving the data; and the A / D converter sends the data to the awakened intelligent weighing device, and the device can directly transmit generated background data to the cloud server in a wireless mode to be backed up and stored. The system is sensitive in response, high in coverage, low in power consumption, stable in operation and particularly suitable for being applied to the fields of small household weighing tools (such as weighing scales) and the like, cloud transmission of data can be achieved, and the observation requirement of a user for weighing changes within a certain period of time is met.

Description

technical field [0001] The invention belongs to the field of production and research of weighing sensors, and in particular relates to a wireless intelligent weighing sensor system. Background technique [0002] my country's weighing instrument industry has huge market potential, but currently there are few varieties of independent products in the market, and the technology is not strong, so the market competitiveness is limited, so further research and development is needed for this, and the weighing sensor is the core of the weighing instrument. The component is the key to the development of the entire industrial chain. It is a device that converts the quality signal into a measurable electrical signal output. It is specially used on the weighing instrument, and can convert the weight of the measured object on the weighing instrument into a certain functional relationship. Electrical signal output. According to different conversion principles, it can be divided into photoel...

Problems solved by technology

However, it is often used for one-time weighing, the data cannot be retained, and the long-distance transmission capability needs to be strengthened. With the rapid development of artificial intelligence, people also put forward higher intelligence requirements for daily appliances, so intelligent weighing As the core module of the intelligent weighing system, the sensor needs to be combined with other vehicles to further enhance the stability of interconnection and long-distance transmission
