How does Hua Weihai think of chip to answer the job below extreme environment to challenge?

Hua Weihai thinks of chip to basically be designed through optimizing hardware, use advanced enclose technology, promotion the circuit stability, job challenge that enhances the means such as interference rejection ability and design of low power comsumption to answer extreme environment to fall, specific as follows:

• Optimize hardware design to increase defend: The consolidate of Lin chip holds embarking Hai Saiqi 3 prevent flat computer, employ unifinication magnalium alloy frame and quadrilateral suspension amortize structure, passed 1.2 meters 6 are fought decline attestation, can resist accident collision. In the meantime, overall through 5 class waterproof, 6 class are dustproof detect, can cut off effectively mist of grit, lunt, salt is right of in-house component erode, get used to the harsh environment such as desert, rain forest.
• Use advanced enclose a technology: If the sea thinks of AC9610 chip to use,enclose a technology advancedly, promoted the dependability of chip and stability, make its can be in – 40 ° C moves to the stability inside the wide lukewarm range of 125 ° C, and have extremely low temperature drift character, can get used to industrial answer miscellaneous environment.
• Promote imitate circuit stability: The data that uses tall stability, optimize circuit layout to wait in order to reduce thermal stress and electromagnetism interference, raise the environmental suitability of imitate circuit. In the meantime, use advanced hot emulation technology and cooling technology, ensure chip can maintain good performance and stability below all sorts of work requirements.
• Enhance interference rejection ability: Partial sea thinks of chip to have outstanding noise to control capacity, if AC9610 chip is below 2Msps sampling rate, letter a confusion of voices is compared (SNR) can amount to 103.5dBFS, be to be as high as 138dBFS more below 1Ksps sampling rate, signal of target of can accurate in strong interference environment resolution and noise signal, ensure the accuracy of data and dependability.
• Design of low power comsumption promotes add boat: If chip of couplet of Hi2131 Cat.1 content is used,exceed small amount chip framework and extremely brief dormancy management, dormancy power comsumption is compressed to 150uA, relatively at be the same as type chip commonly, the power comsumption that keep work falls continuously 30% above, data transmission power comsumption also is reduced 10% , middleman and guarantor holds the extreme environment that can supply inconvenience in a few electric power to work for long. In addition, signal of its be issued to lower levels received function to promote 1dBm more on average than be the same as type chip, in the network brim environment such as well of subterranean parking lot, elevator, still can provide stabler communication link, reduce data to lose bag and communication to interrupt a phenomenon.
• Establish test of lab of extreme operating mode: China stand to drive automatically for Hai Saijian chip ” lab of extreme operating mode ” , imitate – 40 ℃ are pounded to difference in temperature of 150 ℃ instantaneous, through be in lab environment imitate all sorts of extreme conditions, have a large number of tests to chip, discover potential problem ahead of schedule and optimize a design, ensure chip can stabilize the job in actual extreme environment.
