Embodiment 1

[0040] This embodiment provides a sensor signal network transmission converter, including an input interface, a central processing system and an output interface. The input interface is connected with the sensor through the signal line to receive the sensor signal. The central processing system is connected with the input interface to identify and process the received sensor signal. The central processing system includes a signal attribute setting module, a signal identification module and a signal conversion module. The signal attribute setting module sets the type of the sensor signal it receives, such as temperature signal, pressure signal, humidity signal and so on. The signal identification module identifies the sensor signal according to the setting type of the signal attribute setting module, and the signal conversion module converts the identified sensor signal into a network signal supporting a network transmission protocol. The output interface is connected with th...

Embodiment 2

[0047] This embodiment provides a sensor signal network transmission converter, including an input interface, a central processing system and an output interface.

[0048] The input interface is connected to the sensor through the RS485 communication line to receive the sensor signal. The signal connected to the input interface here can be any one of DC signal, pulse signal or AC signal.

[0049] The central processing system is a single-chip microcomputer, including a signal attribute setting module, a signal identification module, a signal conversion module, an ID number setting mechanism, a clock synchronization mechanism, and an addressing mode setting mechanism.

Abstract

A sensor signal network transmission converter comprises an input interface, a central processing system and an output interface, wherein the central processing system comprises a signal attribute setting module, a signal identification module and a signal conversion module, types of received sensor signals are set through the signal attribute setting module, the input interface receives the sensor signals, the sensor signals are identified through the signal identification module according to the set types of the signal attribute setting module, the sensor signals after being identified are converted into network signals supporting a network transmission protocol, and the network signals are sent to a distant receiver by the output interface through a network. The technical problem that a plurality of kinds of transmitted sensor signals can not be identified and processed by a network converter in the prior art is solved. The sensor signal network transmission converter is particularly applicable to the field of sensor networks.

Description

technical field [0001] The invention relates to a network signal converter. Specifically, it is a sensor signal network transmission converter. Background technique [0002] The network conversion of signals is the process of converting ordinary semaphores into network signals that can be transmitted in the network. The electrical components that complete the signal network conversion are called signal network converters. At present, the more common signal network converters include video network converters and audio network converters, but these two converters can only convert AC signals, and the output signals of sensors are generally DC signals, pulse signals or very low frequency Therefore, the sensor signal cannot be converted directly by a video network converter or an audio network converter. [0003] The existing patent document CN201243303Y discloses an IP sensor for network measurement and control, including the front-end part of the sensing element, the A / D and ...
