Wireless network pressure instrument

Abstract

The invention discloses a wireless network pressure instrument, which comprises a pressure information acquisition unit, a signal processing unit, a data processing unit, a display unit, a storage unit, a communication processing unit and a wireless module, wherein the pressure information acquisition unit acquires a pressure signal; the signal processing unit is used for performing analog-to-digital conversion on the pressure signal to form a 24bit digital pressure signal; the data processing unit is used for performing linearization and calibration on the 24bit digital pressure signal, converting the processed signal into an actual pressure number and outputting the actual pressure number; the display unit is used for displaying the actual pressure number; the storage unit is used for storing the actual pressure number obtained by the linearization and calibration; the communication processing unit is used for monitoring channel energy, determining whether a channel is occupied, and sending network request information when no channel is occupied; and the wireless module is connected with the communication processing unit and used for transmitting and receiving wireless signals. The wireless network pressure instrument can perform wireless communication and form a network to enlarge the information range; because a contained battery is adopted, an external power supply is not needed; the wireless network pressure instrument can be connected with a public network and added into a public system; and the network is automatically built without management expense.

Description

technical field [0001] The invention relates to an instrument capable of collecting and processing pressure data, which is mainly used for the measurement and monitoring of natural gas, coal gas, water and other media, for monitoring and recording pressure and temperature, and is powered by an internal battery. Background technique [0002] There are many instruments capable of measuring pressure in the market, such as pressure transmitters, pressure recorders, etc. These instruments either need external power supply and are connected to the control system through wired methods, or they can only collect and record, and cannot be connected to the control center. If the pressure recorder is connected through a wired network, the wiring and cable costs of the instrument are quite large, and the debugging cost is also very high. If the pressure recorder is not connected through a wired network, it is impossible to check the measurement information in time, and it takes a lot of ...

Problems solved by technology

These instruments either need external power supply and are connected to the control system through wired methods, or can only collect and record, and cannot be connected to the control center

If the pressure recorder is connected through a wired network, the wiring and cable costs of the instrument are quite large, and the debugging cost is also very high. If the pressure recorder is not connected through a wired network, it is impossible to check the measurement information in time, and it takes a lot of manpower to transcribe.
