Abstract

The utility model discloses a novel sensor data acquisition module which comprises a serial port, a complex programmable logic device (CPLD), a MIPS processor, a DM9000a Ethernet interface chip, a control switch and an MAX232 chip. The serial port is connected with multiple paths of sensors for acquiring multiple paths of acquisition signals. The CPLD is connected with the serial port and is used for realizing switching of channels between multiple paths of acquisition signals and the start/stop of an analog-digital converter. The MIPS processor is used for receiving the multiple paths of acquisition signals and processing the acquired signals. The DM9000a Ethernet interface chip is connected with the MIPS processor and is used for connecting with a wireless network. The control switch is used for controlling the work state of the MIPS processor. The MAX232 chip for realizing conversion between the TTL level and the 232 level is arranged between the CPLD and the MIPS processor. Through the adoption of the above technical scheme, the novel sensor data acquisition module realizes rapid accurate transmission of multiple paths of sensor signals. Since the novel sensor data acquisition module adopts the DM9000a Ethernet interface chip, signals acquired by the sensors can be transmitted to a remote-end control terminal through Ethernet transmission, and at the same time, instruction signals from the remote-end control terminal can also be received.

Description

A kind of novel sensor data acquisition module

Technical field

The utility model relates to sensor technical field, particularly relates to a kind of novel sensor data acquisition module.

Background technology

As everyone knows, sensor is a class signal pickup assembly very conventional in robotization and intelligent field, in use, the output port of sensor is connected by data line with the input port of controller, but find by long-term practice, there is following defect in traditional sensor use procedure: one, due in actual signal acquisition process, tend to remove to gather multiple signals to a plurality of sensors, therefore this just needs to have a plurality of input ports on a controller, so can cause port nervous, connect up loaded down with trivial details; Two, traditional sensor does not have the signal is far passed function, therefore causes the extraction comparison difficulty of signal.Therefore design and develop a kind of have transmit multiple sensor signal simultaneously, and the novel sensor data acquisition module with remote transmission ability seems particularly important.

Utility model content

The technical problems to be solved in the utility model is: provide a kind of have transmit multiple sensor signal simultaneously, and there is the novel sensor data acquisition module of remote transmission ability.

The technical scheme that the utility model is taked for the technical matters existing in solution known technology is:

A novel sensor data acquisition module, comprising:

Be connected and then obtain the serial ports of multi pass acquisition signal with multiple sensor;

Be connected with described serial ports for realizing the switching of channel between multi pass acquisition signal, the CPLD element that opens/stop of analog to digital converter;

For the MIPS processor that receives multi pass acquisition signal and collection signal is processed;

Be connected the DM9000a Ethernet chip for being connected with wireless network with described MIPS processor;

And for controlling the gauge tap of MIPS processor working state;

Wherein, between described CPLD element and MIPS processor, be provided with for realizing the MAX232 chip of Transistor-Transistor Logic level and 232 level conversion.

Advantage and the good effect that the utlity model has are: by adopting technique scheme, the utility model compare with conventional art have advantages of as follows: one, by adopting technique scheme, the utility model realized multiple sensor signal fast, accurately transmission; Two, because the utility model has adopted DM9000a Ethernet chip, the signal that therefore sensor can be collected transfers to the control terminal of far-end by Ethernet, also can receive the command signal of far-end control terminal simultaneously.
