Working electrode (anode) CO+H
2O → CO
2+ 2H
++ 2e
To electrode (negative electrode) l/2O
2+ 2H
++ 2e → H
2O
CO concentration is big more, and is many more to the oxygen of consumption of electrode.Different with working electrode, the current potential of electrode is then allowed to change.When CO concentration is very low, to electrode potential near the working electrode current potential.When electrode current was increased, current potential also increased, so the effect of potentiostatic circuit is to guarantee to electrode being provided enough electric currents and being in proper voltage.When gas concentration was low, the electric current that working electrode produces was less, at this moment a spot of oxygen of consumption of electrode is kept balance.If but oxygen content is not enough, then can produce other materials, possibly also can produce hydrogen.So, must guarantee during use that oxygen can effectively be input to electrode, this has higher requirement to structure.

One of active label key for design problem is a power consumption, addresses this problem the general two kinds of approach that lean on, the one, select components and parts low in energy consumption, and CC2500 is when the speed of 250kb/s, and the current drain of reception is 13.3mA, in the industry cycle has been very low.The method that another kind improves power consumption is to utilize the software of science to realize, utilizes the electromagnetism arousal function WOR (Wake On Radio) of CC2500 can design a kind of good solution.When CC2500 was in the SLEEP state under the WOR operation, except the counter works of inside realization arousal function, other functions all stopped, and this moment, the power consumption of CC2500 was merely 900nA.When counter arrives programmable fixed time, switch to the IDEL state from the SLEEP state automatically, get into the RX state again.If receive data this moment, just withdraw from WOR and get into normal mode; Can not receive data if be in the Rx state at the appointed time, then get back to the SLEEP state automatically.As long as therefore guarantee at a complete W0R in the cycle, the label overwhelming majority time all is in the SLEEP state, just can reduce the power consumption of label greatly.
After the reader start resets, on channel, send querying command constantly,, get into the RX state and receive data in case receive the commands in return of label.
Label at first carries out CCA (clear channel assessment (CCA)) and detects after receiving the querying command of reader, if testing result is a channel busy, detects after then waiting for random time again; Testing result is a channel idle, then gets into the TX state and sends packet.
The CC2500 chip has carried reception signal strength signal intensity indication RSSI (Received Signal Strength Indicator) module.RSSI is through the distance of the strong and weak measured signal point of the signal that receives with acceptance point, and then positions a kind of location technology of calculating according to corresponding data.Therefore, can estimate the distance between intelligent helmet and the nearest downhole communication substation 16 through the intensity that receives signal, thereby can realize the personnel positioning function, and send locating information to the ground monitoring center.
