Valve opening and closing angle position wireless sensor based on Internet of Things

Abstract

The invention relates to the technical field of sensors, and discloses a valve opening and closing angle position wireless sensor based on the Internet of Things, the valve opening and closing angle position wireless sensor comprises a lower computer and an upper computer, the lower computer transmits valve rotating disc information to the upper computer, and the upper computer is used for receiving the information sent by the lower computer and transmitting the information to a user. The lower computer comprises a valve turntable and a circuit board, the circuit board is provided with a plurality of groups of sensors, the plurality of groups of sensors are uniformly distributed on the outward extending half circle of the valve turntable, a magnet pointer is arranged on a main shaft of the valve turntable, and the plurality of groups of sensors are matched with the magnet pointer to trigger different signals. According to the invention, the position of the valve turntable can be accurately determined through the cooperation of the sensors and the magnetic pointer, a message is received to a second microprocessor through a wireless receiver in the upper computer, and the user can check the message through the cooperation of an RS485 interface circuit and external configuration software.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a wireless sensor for opening and closing angle positions of valves based on the Internet of Things. Background technique [0002] Industrial valves play the functions of controlling fluid on-off, adjusting fluid pressure and changing the direction of fluid flow in the pipeline system. There are pneumatic, electric and other methods to control valve actuators, and the control method usually adopts wired transmission. This control method is suitable for ordinary places such as industrial factories, with perfect working conditions, convenient wiring, and various power sources. For outdoor and remote environments, it is not conducive to laying cables, air pipes, etc., and the flexibility is poor, and it is easily damaged if exposed to the wild for a long time, which is not conducive to maintenance. [0003] In some long-distance pipeline transmission systems, a certain number of v...

Problems solved by technology

For outdoor and remote environments, it is not conducive to the laying of cables, air pipes, etc., and the flexibility is poor, and it is easily damaged if exposed to the wild for a long time, which is not conducive to maintenance

[0003] In some long-distance pipeline transmission systems, a certain number of valves are distributed along the pipeline system. The distance between the valves is far from each other, and they are all far away from the monitoring center. Manual methods, or pneumatic and electric methods based on wired transmission control valve, high cost

When the cable is damaged, or it is impossible to determine which valve is damaged, in order to confirm the latest status of the valve, it is often necessary to send personnel to check one by one. This method is labor-intensive and time-consuming, so it is necessary to remotely control the valve in a wireless way, and The valve terminal is equipped with a power source and a power supply device to ensure its normal operation within the design life cycle. For this reason, we propose a wireless sensor for valve opening and closing angle position based on the Internet of Things
