The power spectral density of very little, i.e. signal is very low, so using the Resistant DS Spread Spectrum System of spread spectrum code sequence spread-spectrum, can be
Under the background of interchannel noise and thermal noise, communicated on very low power spectrum density.
（3）With anti-fading, anti-multipath jamming ability：Due to the signal spectrum of spread spectrum communication system it is broadened, so expand
Display system has the ability of potential mitigating frequency-selective fading, additionally, spread spectrum communication system can also be dry efficiently against multipath
Disturb.
（4）With multiple access capability, it is easy to accomplish CDMA：Spread using pseudo-random sequence in spread spectrum communication system,
Can be by the use of different pseudo-random sequences as the address code of different user, so as to realize CDMA in actual communication system
Communication.
（5）The numeral of gas meter counter character wheel is directly read, it is not necessary to accumulated pulse, conversion numerical value, without the need for storing number
According to, there are no cumulative errors, it is truly realized " meter reading ".
（6）The devices such as the enumerator in electronic section and gas meter do not have Mechanical Contact, are completely independent, and do not affect base table
Measuring accuracy.
（7）Directly transmit data, and non-pulse signal.It is not only affected by mechanical shock, while to electromagnetic interference
With high anti-interference, so can stable, accurately and reliably realize metering under complicated use environment.
（8）Without the need for power supply, moment powers when only checking meter for routine work.This is the basic spy for being different from pulsed gas meter, flow meter
Point, it is to avoid the error in dipping caused due to power supply instability or failure and substantial amounts of maintenance work.
（9）Gas meter, flow meter realizes all the life zero error with teletransmission data.
