Wireless pressure sensor system

The rapid development of wireless communication technology and computer technology has been applied to sensor technology. It makes wireless data collection of pressure sensors possible. Its unique performance is more advantageous than traditional pressure sensors. It can be used in areas where wiring and power supply are difficult, areas where people cannot reach. Such as high temperature, severe cold, high humidity areas, contaminated areas or areas where the environment is destroyed. And some temporary occasions. Realized the sensing system Remote testing. This is also an inevitable trend of testing in the information age.

System design

The pressure sensor wireless acquisition system designed in this paper is composed of the front-end sensor data acquisition transmitter part and the terminal data receiver part. Figure 1 shows the block diagram of the transmitter part (upper) and the receiver part (lower) of the sensor data collection.

The sensor data acquisition and transmission part is composed of a pressure sensor, a temperature sensor, a signal processing part, a microprocessor (generally a microcontroller) and a wireless transmission circuit.

Pressure and temperature sensors acquire pressure and temperature values ​​of the surrounding environment.

The signal processing part includes the preceding channel, program-controlled amplifier and A/D converter. Its function is to extract and amplify the analog signal of the sensor under program control and perform analog/digital conversion.

The microprocessor is responsible for controlling the work of each part of the system and processing digital signals. The wireless transmission circuit is under the control of the microprocessor. The encoder encodes and processes the collected information data and transmits it with the transmission module.

The data receiving part is composed of wireless receiving circuit, microprocessor and display part.

Receive data from radio under the control of a microprocessor. After receiving a set of format data, the decoder in the receiving circuit decodes the format data. The current pressure information of the environment is obtained. Then the pressure information is displayed on the LED receiving panel.

How Wireless Pressure Transmitter Works ?

Install the wireless pressure transmitter on the pipeline.
When the medium in the pipeline acts on the sensitive element, it is pressed.
Its internal circuit detects an electrical signal proportional to the process pressure.
After the signal is accurately amplified and compensated by the linear amplifier circuit.
Enter the microprocessor to measure, process and display data.
And wirelessly transmit the measurement data to the remote terminal equipment.
The wireless pressure transmitter adopts the wireless remote transmission module added on this basis. It can form a pressure acquisition system with our intelligent wireless receiving terminal.This system changes the transmission mode and switching power supply mode of RS485 and 4-20mA in the industry.
