Yadda ake samun RSSI da SNR akan isar da sako mara matuki?

tambaya: Na lura cewa shafin yanar gizon TX900 baya aika bayanan RSSI zuwa mai sarrafa jirgin; ba zai haifar da rashin tsaro ba lokacin da hanyar haɗin rediyo ta ɓace. Shin akwai wata hanya ta aiki a kan wannan batu?

Amsa: Bayanan halin haɗin mara waya ta RSSI yana buƙatar abokan ciniki (kamar masu kula da jirgin) don aika umarnin AT da hannu don samun shi. Ana iya samun ta ta hanyoyi biyu:

1. Sanya UART3 (tashar data 3rd) a matsayin AT umarni serial port, sannan aika umarnin AT ta hanyar UART3 (D3) a samu. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
2. Sabunta sigar firmware 1.5.1 ko sama, ta yadda za a sami ƙarin uwar garken TCP a ciki don abokan ciniki don shiga ta hanyar TCP don aika umarnin AT don samun matsayin mara waya..

Ga bayanin injiniyanmu.

1. Ana amfani da hasken LED don nuna halin haɗin mara waya (misali, idan an katse hanyar haɗin mara waya, hasken zai fita), kuma babu keɓaɓɓen fil na waje don sanar da abokin ciniki na sarrafa jirgin.
2. Babban tsarin mu yana da GPIO fils, amma suna da alaƙa da fitilun LED. Modul ɗinmu na vcan1681 shima yana da irin waɗannan fil, amma a halin yanzu, Hakanan ana haɗa shi da fitilun LED.
3. Idan kuna shirye ku kashe kuɗi akan gyare-gyare, za mu iya keɓance maka na musamman, kuma za'a iya canza yanayin waje.
4. Lokacin da abokan ciniki ke amfani da hanyoyin haɗin bayanan bidiyo mara waya mara waya ta mu, tabbas za su buƙaci samun bayanan kula da jirgin sama ta hanyar tashar jiragen ruwa ko tashar sadarwa zuwa tashar jiragen ruwa.
5. Hanyar gama gari ita ce ƙara tabbatarwa zuwa software na tashar ƙasa da software na sarrafa jirgin don auna amincin hanyar haɗin mara waya. A wannan lokacin, za ku iya fahimtar ingancin hanyar haɗin gwiwa gaba ɗaya da abubuwan da suka faru na yanke haɗin gwiwa a cikin software, sannan saita ƙofa a cikin software don ƙararrawa da sarrafa ta.
6. Wato a ce, lokacin da software ta tashar ƙasa ta sami bayanan tsarin tsarin jirgin sama ta hanyar haɗin yanar gizon mu mara waya idan adadin kuskuren ya wuce wani ƙira., ana iya la'akari da cewa hanyar haɗin mara waya ta kai matakin da ba za a iya dogara da shi ba kuma yana buƙatar sarrafa shi. Wannan al'ada ce ta gama gari tsakanin kamfanonin jiragen sama na kasar Sin.

Magana RSSI SNR don samfuran da ke ƙasa

tambaya: Za ku iya haɓaka mini sabon samfuri? Yana da sauƙi don samun RSSI da SNR?

Shin kawai kuna buƙatar samun matsayin ainihin lokacin ko an haɗa / cire haɗin haɗin mara waya? Ko muna buƙatar samun ko da RSSI?

Domin GPIO zai iya gane jihohi biyu ne kawai: 0/1, za a iya amfani da shi kawai don nuna ko an haɗa / cire haɗin haɗin mara waya, kuma ba zai iya bayyana ƙimar RSSI ba (Har yanzu ana buƙatar samun ƙimar RSSI da SNR ta umarnin AT)

Idan kana buƙatar mu mu ba da rahoton rayayyun bayanai kamar RSSI da SNR ban da matsayin hanyar haɗin da aka haɗa/katsewa., to dole ne ku yi aiki bisa ga aikin da aka keɓance. Kuna buƙatar bayyana buƙatun ku a sarari, docking musaya, da dai sauransu. (maimakon A cikin jumla mai sauki), ta yadda za mu iya tantance wahalar haɓaka gyare-gyare da hanyoyin da za mu bi.

Menene SNR da RSSI?

SNR (Rabon sigina-zuwa amo) is a ratio-based metric that measures your signal in relation to the noise.SNR is made up of two values that are measured as a positive number between 0db and 120db, with the closer it is to 120db, the better: signal value and noise value, both of which are commonly reported in decibels (DB).

TheRSSI (Received signal strength indication) will look at the Signal (Also known as RSSI) first this value is measured in decibels from 0 (zero) to -120 (minus 120) now when looking at this value the closer to 0 (zero) the stronger the signal is which means it’s better, typically voice networks require a -65db or better signal level while a data network requires -80db or better.

Because the signal is affected by the AP’s transmit power and antenna, as well as the client’s antenna, the normal range in a network would be -45db to -87db depending on power levels and design.

Ƙarfin sigina (RSSI, “signal strength”, Signal/Noise Ratio). It is often preferable to concentrate on RSSI.

• RSSI -90 dBm: This signal is incredibly faint, and it is at the limit of what a receiver can receive.
• RSSI -67dBm indicates a rather strong signal.
• RSSI greater than -55dBm indicates a very strong signal.
• RSSI > -30dBm indicates that your sniffer is right adjacent to the emitter.

tambaya: In case of signal loss from the operator, will FailSafe be activated?

Amsa: Failsafe is the function of the flight controller. We just provide signal transmission and transmit transparent data. What data do you give us, We transmit them for you.

tambaya: Unless your receiver reports that the connection is lost, FailSafe is not activated.

Amsa: You can get the signal strength. Mai watsa bayanan bidiyon mu mara waya da mai karɓa ba su da wannan aikin. Na yi imani cewa watsa hoton mara waya na masu samar da kayayyaki na kasar Sin ba shi da wannan aikin, sai dai saitin jirgi mara matuki ya riga ya yi aikin rashin tsaro.
