Problems solved by technology

General wireless sensor devices mainly use close-range objects less than tens of meters as the measurement objects. When the ambient temperature and power supply voltage change within the rated range, the measurement accuracy will be affected, resulting in poor anti-interference ability; traditional mechanical adjustment The zero method is to add a potentiometer to the circuit, and use the method of changing the value of the divided voltage to perform zero adjustmen

Abstract

The invention discloses a wireless sensor system, and the system comprises a sensor, a signal conditioner, a voltage-stabilizing circuit, an analog/digital converter, a main control module, a storage module, a communication interface, an upper computer, a power module, and a zero setting module. The sensor, the signal conditioner, the voltage-stabilizing circuit, the analog/digital converter and the main control module are sequentially connected. The main control module is connected with the storage module, the power module and the zero setting module, and is connected with the upper computer through the communication interface. The system can achieve the real-time collection and processing of the data through the upper computer, is high in measurement precision, is strong in anti-interference capability, is long in transmission distance, is convenient for zero setting, and is suitable for popularization and application.

Description

technical field [0001] The present invention relates to the technical field of sensors, in particular to a wireless sensor system. Background technique [0002] A sensor (English name: transducer / sensor) is a detection device that can feel the measured information, and can transform the sensed information into an electrical signal or other required form of information output according to a certain rule, so as to meet the information requirements. transmission, processing, storage, display, recording and control requirements. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. Usually according to its basic perception function, it can be divided into ten categories such as thermal sen...
