Simsiz video ma'lumotlar audio uzatuvchi va qabul qiluvchi, Ikki tomonlama, Download-Upload
A customer saw our real test video about the 2 vatt quvvat kuchaytirgichi 27km uzoq masofali simsiz video uzatuvchi va qabul qiluvchi. He placed an order for this equipment. He hoped we would also bring the transmitter to the top of the mountain and the receiver to the seaside for testing before shipment. We have done our best to meet the needs of the customers. So we did it and created today’s video. If you want to learn about the actual transmission effect of long-range HD 1080P wireless video transmission, as well as how to operate it. Please keep watching.
Let’s begin by looking at the test location and distance on Google Earth. Search Meishajian, which is located on Shenzhen’s third highest peak, for no obstructions and simulate the situation of an aircraft with a transmitter in the air, ensuring that the test is within the line of sight. There are many high-rise buildings in a coastal city like Shenzhen. Finding a test environment with a line of sight and a distance of 30 kilometers is difficult. A T-shape is formed from here to the seaside of Nan’ao. Our receiving station is on the beach, and we can see the top of the transmitter from a distance of 27 kilometr.
We used the good distance tool to determine that the distance between the transmitter and the receiver is nearly 27km. In the following video, we can see from the receiver’s web UI page that the current transmitter to receiver distance is 27390 metr.
Now let’s take a look at the situation of the transmitter on the mountain. The transmitter, IP network camera, and battery are placed on the rock. The trekking pole and red bubble belt make a red flag, which is fluttering in the wind so that the picture on the receiver screen is not static, it can be observed whether the wireless transmission video is smooth. The receiver is on the other side of the sea. The black transmitter is connected to two 30cm height transmitting antennas, the left part is the IP network camera, which is connected to the transmitter with a network cable, and the right part is a 12V battery, which powers the transmitter and the IP network camera.
Please try to position the transmitter and receiver vertically while transmitting. The signal strength will then be strong. Allow me to turn the transmitter and receiver in my hand, and the receiver monitor video will begin to move. The receiver will determine whether or not the video is smooth.
Now let’s take a look at the picture of the receiver.
The receiver is connected to the computer through the network cable. We can use the RTSP player on the computer and see the smooth picture directly.
We can also enter 192.168.8.11 in the browser to open the setting page of the receiver. On this parameter setting page, we can see various parameters of the current transmitter and receiver. An important parameter in this table is the distance and the signal strength. Now we can see that from the current transmitter to the receiver distance is 27390 metr.
In the computer’s RTSP player, we can see that the wireless video transmission picture from the mountain transmitter has been kept very smooth, and the little red flag and the grass are fluttering in the wind without any lag, frozen, mosaic.
We are using an IP network camera to test, if your camera has HDMI 1080P, 4K HD, SDI, AHD, or CVBS output, we also can add an encoder to the transmitter, connect your video output, and send out the IP living streaming to the transmitter. Qabul qilgichda, output the video to a computer through a network cable, or to a network video recorder.
It can be seen that the picture is very smooth,
Here we continue to play the videos recorded by the transmitter and receiver on the computer, and we can also answer some questions that some clients care about and always asked.
Two-Way full duplex Wireless Video Data Audio Transmission
Birinchidan, this set of wireless video data transmission transmitters and receivers is a two-way full duplex transmission system, it is like setting up an invisible wireless network in the air, two computers can be connected, and ping can be used in the computer’s cmd command state. In addition to transmitting video, data and audio can also be transmitted.
Power Amplifier options 2W, 5W, and 10W to support longer distance
Ikkinchi, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. Masalan, 300mW, 2 Vatt, 5 Vatt, 10 Watts power amplifier, the corresponding transmission distance is 7 km, 15 km, 30 km, 80 km, 100 km, the farthest can be transmitted to 150 km, we also have a 110 km The actual test video. If you are interested, I can also edit it and upload it for everyone to watch.
Up to 150Km, 4 times of English Channel Width
uchinchi, what is the concept of supporting up to 150 kilometr? It is equivalent to 93 miles. The UK is separated from Europe by the English Channel, and its width is only 35 kilometr, anavi, 150 kilometers is equivalent to the width of 4 times English Channels. It can also transmit high-definition videos with good signals.

Tez-tez so'raladigan savollar
Ushbu transmitter va batareyaning quvvat manbai ikkalasi ham 3A@28V. Oddiy vaqtda, biz sinovdan o'tkazgan batareya 7AH, u 2 ~ 4 soat ishlashi mumkin. Agar siz 15AH zaryadlanuvchi batareyani sotib olsangiz, taxminan 4 ~ 8 soat davomida uzluksiz ishlashi mumkin.
Web UI parametrida nafaqat chastotani osongina almashtiring, chastotani o'zgartirgandan keyin, shuningdek, ichidagi Quvvat kuchaytirgichni va bir xil chastotali uzatuvchi va qabul qiluvchi antennani o'zgartirishi kerak. Shunday qilib, xaridor etkazib berishdan oldin qaysi chastota kerakligini tasdiqlashi kerak. Antenna ushbu chastotaga muvofiq moslashtirilgan.
RF kabeli haqida, our engineer doesn't recommend that you used it so long. Bir metrli RF kabeli uchun 0,5 dB kamayadi. Uchun 3 metrli RF kabeli, signal kuchi 1,5 dB ga kamayadi.
Uzoq masofani qo'llab-quvvatlash uchun, RF kabelidan kamroq foydalanganingiz ma'qul 1 metr?
Aslini olib qaraganda, transmitter juda kichikroq, transmitterdan uzatuvchi antennaga qisqa masofani saqlash yaxshiroqdir. Transmitterning quvvat manbai va kameradan uzatuvchiga chekilgan kabeli uzoqroq bo'lishi mumkin, chunki RF kabeli kabi yo'qotishlar yo'q..
ha, standart video kirish IP RJ45 chekilgan portidir, agar sizning kamera HDMI yoki SDI yoki AHD, bu muammoni hal qilish uchun faqat bitta kichik kodlovchi quti. Iltimos, quyidagi modelni tekshiring.
- Agar sizning hududingizda DVB-T yoki DVB-T2 raqamli televizion signal mavjud bo'lsa, The Televizor chastota diapazoni 170-860 MGts, u 800 MGts chastotaga ega, shuning uchun 1.4G ni tanlash yaxshidir.
- Chunki GPS antennasi GPS signalini oladi va drondagi GPS yo'nalishi yuqorida, bizning transmitter antennamiz signalni erga yuborish uchun pastga qaratilgan. Natijada, GPS-da 1,4G chastotasi ta'siri juda kam.
Paket hajmi 125 x 23 x 11 sm. Brutto vazni：3.72KG， Hajmi Og'irligi：7.5KG
Mana to'liq to'plam rasmi.
Chastotani sakrash haqida, muhandisning siz uchun ba'zi takliflari bor.
- Tizim chastota diapazoni 20 Mb bo'lgani uchun, agar sizning tarmoqli kengligingiz 20 Mb tanlangan bo'lsa, keyin sakrab bo'lmaydi (faqat bitta nuqta). Agar tarmoqli kengligi 10 Mb tanlangan bo'lsa, keyin sizda sakrash uchun ikkita ochko bor, agar tarmoqli kengligi 5 Mb tanlangan bo'lsa, keyin sizda bor 4 sakrashga ishora qiladi.
- Agar 1410 MHz tiqilib qolgan bo'lsa, keyin 1420Mhz ham tiqilib qoldi, chunki chastota juda yaqin.
- Chastotani sakrashda, ma'lumotlar yoki video uzatish uzilib qoladi, va videongiz muzlatiladi.
- Oddiy vaqtda, sakrashni tanlash yaxshidir EMAS.
- Agar sizning uzatish masofangiz 15 ~ 22 km dan kam bo'lsa, keyin biz tanlash uchun yana bir variant bor, chastotasi 110 Mb, va hatto 20Mb tarmoqli kengligini tanlasangiz ham, bor 5 chastota sakrash uchun tanlash uchun nuqta.
Agar siz S.busni qo'llab-quvvatlashingiz kerak bo'lsa, keyin jo'natishdan oldin bizga xabar bering, va biz RS232 ni TTL ga o'zgartiramiz.
Bizning TX900-da uchta RS232 porti mavjud. Agar sizga S.busni qo'llab-quvvatlash uchun kerak bo'lsa, S.BUS dan RS232 ga qo'shimcha bitta kichik konvertor kerak bo'ladi. ( Mini SBUS Uart-dan Sbus-ga o'tkazish moduli, Sbus - Uart ).
Iltimos, etkazib berishdan oldin sizga sbus porti kerakmi yoki yo'qligini ayting. Bizning muhandisimiz D2 portini RS232 dan Sbusga o'zgartiradi.
RSSI simsiz ulanish holati ma'lumotlari mijozlarni talab qiladi (parvoz boshqaruvchilari kabi) uni olish uchun AT buyruqlarini qo'lda yuborish. Uni ikki yo'l bilan olish mumkin:
- UART3 ni sozlang (ma'lumotlar porti 3) AT buyrug'ining ketma-ket porti sifatida, va keyin UART3 orqali AT buyruqlarini yuboring (D3) olish. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
- Mikrodastur versiyasini yangilang 1.5.1 yoki yuqorida, Shunday qilib, mijozlar simsiz maqomini olish uchun AT buyruqlarini yuborish uchun TCP orqali kirishlari uchun qo'shimcha TCP serveri mavjud bo'ladi..
- LED chiroq simsiz ulanish holatini ko'rsatish uchun ishlatiladi (misol uchun, simsiz aloqa uzilgan bo'lsa, yorug'lik o'chadi), va mijozning parvoz boshqaruvini xabardor qilish uchun maxsus tashqi pin mavjud emas.
Yoki qarang UART AT buyruqlar ro'yxati bu yerda.
yoki qarang https://ivcan.com/how-to-get-the-rssi-and-snr-on-the-drone-transmitter/
- Simsiz video uzatishimizning ketma-ket porti shaffof, va parvoz boshqaruvchisiga hech qanday ma'lumot faol yuborilmaydi. Bu yerosti stansiyasi tomonidan boshqariladi.
- It won't send the failsafe command, lekin siz signal indikatoridan havola holati chiroqini ko'rishingiz mumkin.
- Bu erda havola holati signal kuchi ko'rsatkichi anglatadi
- Yorqin emas: Modulning simsiz aloqasi ulanmaganligini bildiradi
- qizil: Modulning simsiz aloqasi ulanganligini bildiradi, lekin simsiz signal kuchi juda zaif
- apelsin: Modulning simsiz aloqasi ulanganligini bildiradi, va simsiz signal kuchi o'rtacha
- yashil: Modulning simsiz aloqasi ulanganligini bildiradi, va simsiz signal kuchi juda kuchli
- Siz ushbu funksiyaga ega bo'lishingizni tushunamiz, Agar samolyot parvoz paytida signalni yo'qotsa, u uyga qaytmaydi, chunki parvoz boshqaruvchisi rc aloqasi yo'qolganini tushunmaydi.
- Siz havola holatining LED yorug'ligini ko'rishingiz kerak, agar u to'q sariq yoki qizil bo'lsa, siz samolyotni oldindan nazorat qilishingiz kerak.

4K video qo'llab-quvvatlanadi.
4K video oqimi odatda 8Mbps dan ortiq, va 1080P video odatda 2M dan ortiq, shuning uchun 4K videoni uzatishda simsiz video uzatish masofamiz 1080P dan qisqaroq bo'ladi..
Bir so'z bilan, videoning aniqligi qanchalik baland bo'lsa, uzatish masofasi qanchalik qisqa bo'lsa.
Videoni siqish kichikroq, va uzatish masofasi uzoqroqda qo'llab-quvvatlanadi.
Video uzatish jarayonida, agar ma'lumotlar yo'qolsa, rasmda mozaik yoki turg'unlik paydo bo'ladi, muzlash va boshqa hodisalar.
Simsiz aloqa darajasida cheklangan miqdordagi qayta uzatish bo'ladi (albatta, agar vaziyat yaxshi bo'lmasa, ma'lumotlar xatosi ham sodir bo'ladi). Oxiridagi yuqori qatlamli dastur bundan xabardor bo'lmaydi, Shuningdek, u jo'natuvchidan qayta yuborishni so'ramaydi.
Masofa uzaytirilgandan keyin ma'lum bir nuqtada simsiz aloqaning signali yaxshi bo'lmasa, va har doim kichik xatolar mavjud, uni har doim qayta uzatish uchun loyihalash mumkin emas, shuning uchun oxirgi foydalanuvchi tajribasi juda yomon bo'ladi.
Simsiz aloqa qatlami cheklangan qayta uzatish mexanizmiga ega. Biz video uzatish qatlamida uzatish uchun tcp protokolini sinab ko'rdik (tcp protokoli orqali yuqori qatlamda qayta uzatishga harakat qilmoqda), ammo sinov aniq yaxshilanish yo'qligini aniqladi, va bu boshqarib bo'lmaydigan kechikishlarga ham olib keladi.
- Samolyot tomonida hosil bo'ladigan issiqlik er yuzidagi issiqlikdan ancha katta. Agar fan ishlayotgan bo'lsa, pastki fanning havo kirishi va chiqishini tekshiring (har ikki uchida issiqlik qabul qiluvchilarning pozitsiyalari) bloklanadi
- Havo bloki uzatgichining quvvat manbaini 24V dan 12~18V ga o'zgartirib ko'ring (uzatish quvvati taxminan 35 ~ 36DB gacha kamayadi)
- Quyidagi AT buyruqlari bilan samolyotning uzatish quvvatini biroz kamaytiring: AT^DSSMTP="23" Sozlashdan keyin qayta yoqing
savol: Ushbu sozlamalar modulning maksimal quvvati? (24 dBm)
javob: 24dBm - ulanish modulining maksimal chiqish quvvati, va PA daromadi (taxminan 14 dBm) qo'shish kerak. 24V quvvat manbai PA chiqishidan keyin haqiqiy uzatish quvvati taxminan 38dBm ni tashkil qiladi.

Havo birligi orasidagi farq (uzatuvchi) va tuproq birligi (qabul qiluvchi) ikki nuqtadan iborat:
Ulardan biri qurilma turi: Havo birligi (uzatuvchi) bo'ladi kirish tuguniga va yer birligi (qabul qiluvchi) bo'ladi markaziy tugun.
Ikki - pastga va yuqoriga ulanish tezligi nisbati. 30 km dan ortiq, eng yaxshi nisbati hisoblanadi 4:1 yoki 3:2.
If you don't want to connect the receiver ethernet cable directly to the computer. Keyin mahalliy tarmoqdagi qabul qiluvchiga kirish oson emas.
Mana siz uchun ikkita yechim.
1. Kompyuter tomonida 192.168.1.x tarmoq segmentining IP manzilini qo'shing (kompyuterni bir nechta tarmoq segmenti IP manzillari bilan sozlash mumkin)
2. Simsiz video ma'lumotlarni qabul qiluvchining IP-ni o'zgartiring 192.168.1.12 mahalliy tarmoq bilan tanishish uchun 10.220.20.x tarmoq segmenti manziliga.
Qo'shimcha savollar va yechimlar uchun, Iltimos, mahalliy tarmoqdagi hamkasbingiz yoki muhandisingiz bilan gaplashing, bizning qabul qiluvchimiz IP manzilli kompyuterga o'xshaydi, u tarmoq segmentining IP manzilini bir xilda saqlashi kerak, misol uchun, 192.168.1.xxx.
- ha, Buning uchun uchta yechim bor.
- TX900 uchta ma'lumot portiga ega. Turli shaffof ketma-ket portlar orqali farqlang, masalan, D2 releyli samolyotni boshqarish uchun va D3 missiya samolyotlarini boshqarish uchun. Kamchilik shundaki, ko'rsatmalarni alohida yuborish uchun TX900 qabul qilgich ikkita ketma-ket portga ulanishi kerak..
- Ma'lumotlarni ommaviy yuborish uchun bir xil shaffof ketma-ket portdan foydalaning, va keyin qatlam protokollarini qo'shing (sarlavha ma'lumotlari kabi) qaysi samolyot ma'lumotlarni qabul qilishi va qayta ishlashi kerakligini aniqlash uchun ma'lumotlarga. Kamchilik shundaki, ma'lumotlarni yuborish va qabul qilish jarayoni murakkab.
- Yoki ikkita qabul qiluvchidan foydalaning: Bitta qabul qiluvchi missiya samolyoti uchun (uzatuvchi), va yana bir qabul qiluvchi takrorlovchi dron uchun. Ulanish va ishlash osonroq.
