Magnetic sensor output circuit and data wireless transmission and control system method

Abstract

The invention provides an anisotropic magnetic sensor output circuit and a data wireless transmission and system control method. A differential output circuit is adopted, a positive output path and a negative output path are respectively connected to an amplifier for a two-path instrument and are subjected to amplification so that two paths of differential signals are produced. The differential signals are connected to a differential ADC driver. The driver provides enough electric currents for a later circuit. Positive and negative output parts of the driver are respectively connected to an analog input end of a first wireless transceiver module chip with an ADC. In the module, through AD conversion and primary processing, the data is sent to a second wireless transceiver module through a wireless channel. The second wireless transceiver module is connected to a computer. The data received through the second wireless transceiver module is transmitted to the computer through USB. A signal can be transmitted and amplified through a differential line transmission operational amplifier. Compared with a single-ended transmission method, the method provided by the invention can effectively inhibit interference noise in a line and improves a signal transmission distance.

Description

technical field [0001] The present invention relates to a control system of a data wireless transmission method, in particular to a magnetic sensor output circuit and data wireless transmission and control system method, the magnetic sensor output circuit and data wireless transmission and control system method are mainly used for measuring and monitoring equipment The operating state belongs to the technical field of detection. Background technique: [0002] The state monitoring of equipment usually refers to judging the operating state of the equipment by measuring and monitoring the state information or the change of characteristic parameters during the operation of the equipment. The basis is that if the equipment is abnormal or faulty, the state information or characteristic parameters will change accordingly. Through the analysis and processing of these state information and characteristic parameters, it is possible to predict and judge the abnormal or faulty condition...

Problems solved by technology

[0007]So although these above-mentioned patents all relate to magnetic sensor, and all have improved magnetic sensor or the method for utilizing magnetic sensor to detect, but all do not have how to prevent magnetic The sensor is magnetized by an external magnetic field to propose improvements. Therefore, under a strong magnetic field, the problem that the magnetic sensor is often magnetized by the external magnetic field still exists. At the same time, the signal detected by the sensor will be affected by environmental parameters such as external temperature. The magnetic sensor The transmitted signal is prone to distortion and still needs further improvement
