I want a wireless video transmitter for my AGV ground EOD robot

I want a wireless video transmitter for my AGV ground EOD robot

I have 4 IR bullet cameras from the Dahua company. Every 2 meqapiksel. I want to convert them into one video feed (4 videos in 4 corners of the screen, makes 1 video) and send the 1 video wirelessly to a receiver, and see that 1 video (olan 4 video feeds in 4 corners) in an hdmi screen. So video is the unidirectional transmission. Mən avtomobilə audio və rəqəmsal məlumat göndərəcəyəm və Avtomatlaşdırılmış İdarəetmə Vasitələrindən audio və rəqəmsal məlumatları alacağam. Beləliklə, iki yönlü audio və iki yönlü məlumat ötürülməsi. 400 MHz 1km NLOS.

I need the ground robot video transmitter always to keep at Channel One video.

sual: Video kanalı PC interfeysi proqramı PlatformSetv1.17.14.zip vasitəsilə dəyişə bilər. Video kanalını dəyişdim 1; Kanalda video ala bilirem 1. Fərdi və birlikdə ötürücü və qəbuledicidəki parametrləri dəyişdirməyə çalışdı. Sistem yenidən başladıldıqda, video sistem kanalı Dörd şəkilə dəyişdi. Parametrlər sistemdə saxlanmır. Zəhmət olmasa, mənə kanal üçün sistemin yenidən başlaması üçün bir həll təqdim edin 1 yalnız.

cavab: Bu veb idarəetmədə təyin edilə bilər.

I hope that the data transmission of your ground robot UGV video transmitter and receiver will not retransmit unsent data when it resumes after a signal interruption.

Ötürücü məlumat ötürürsə, qəbuledici diapazonu pozulduqda. When the receiver comes in range it delivers the data to the receiver with data it held previously, and after a few seconds, then it transmits the new data. Is there any provision that it should not try to re-transmit the old data if the receiver range starts breaking? Then it should discard the data. Is there any software configuration to change this parameter to control retransmission?

We have tried the PC interface software PlatformSetv1.17.14.zip. There is no configuration in basic settings to control retransmission. When we try to open Advance Settings, it asks for a username and password. Unable to open advanced settings. cavab: İstifadəçi adı: admin, parol: 123456

Please provide me with a solution to reduce the retransmission of data, when the receiver range starts to break.

cavab: Zəhmət olmasa qəbuledicini master rejiminə, ötürücünü isə qul rejiminə qoyun.

Is it normal for the case temperature to be very high?

Göstərilən temperaturdur 65 dərəcə C, bu da xarici temperatur olduqda 9 dərəcə C. Yayda nə olacağını təsəvvür edə bilərsiniz 45 dərəcə C.

cavab: Bu yerüstü robot mini avtomobil dəstinin video ötürücü avadanlığının ötürmə gücü 4W-dir, müəyyən miqdarda istilik əmələ gətirən. İstifadə zamanı, hava kanalı tələb edir (fanat) və ya istiliyi passiv şəkildə yaymaq üçün robotun qabığının istifadəsi. Möhürlənmiş bir mühitdə quraşdırılıbsa, istilik yığılmasına səbəb olacaq.

How do you test the latency of the wireless video transmitter and receiver?

1. Saniyəölçəni adətən kompüterdə işlədirik.
2. Və sonra kompüterin saniyəölçəni ilə qarşılaşmaq üçün simsiz ötürmə sisteminin kamerasından istifadə edirik.
3. Saniyəölçən video simsiz ötürmə sisteminin ötürücü və qəbuledicisindən keçdikdən sonra, we can see the currently displayed stopwatch time on the HDMI display.
4. Through the continuous shooting function of the mobile phone, take pictures of the delay between the two stopwatches.
5. And subtract the values between the two stopwatches to get the data that is the delay of the current wireless transmission system.
6. In the obtained data, average the maximum data and the minimum data to get the average delay of this wireless transmission system.

How to calculate the camera latency?

Ultra-low latency is very important for wireless transmission equipment. Vcan1935 is a one-way four-way video, two-way audio and data wireless transmission system. It is suitable for ground robots or mini vehicles.

Let’s test its delay and latency. The black box is a wireless video transmitter. It supports four AHD or CVBS camera video input simultaneously. Let’s take a look at the silver receiver. The receiver is connected to this display via an HDMI cable. This is a computer playing a stopwatch, and we can clearly see the changes in milliseconds.

The camera is an AHD camera for video input. It is connected to our video transmitter which is to be tested for time delay. This camera is filming the computer monitor playing a stopwatch, showing changes in milliseconds. This live video will go through our wireless transmitter, wirelessly transmit to our video receiver,
Displayed on this screen, you can see a millisecond stopwatch. video.
Now I use my mobile phone to take pictures of these two screens continuously. Observe and calculate the time difference between the stopwatches on these two screens. By subtracting the two data points, we can get the delay from the transmitter camera to the receiver display.

The stopwatch on the computer screen is captured by the camera and transmitted to the wireless transmitter. Via our wireless transmission system, the receiver receives it and displays it on the screen. The currently calculated delay includes camera encoding, simsiz ötürmə, receiver decoding, and HDMI monitor display.

Now let’s pause the video and see what the current delay is: 000+215-997=218ms. Pause the video again and calculate the time difference. 871-637=234ms. Because the time of each calculation may be different, you need to calculate the average value. Əlavə olaraq, the encoding time of the camera is also different. It is best to connect the camera to the display screen and calculate the camera delay separately. From the total delay, we need to subtract the camera delay and the display time of the HDMI screen, which is the delay of the wireless transmitter and receiver. The minimum latency of our video encoding board is 50-80 ms. In any case, the latency of the entire system will be less than 250 ms.

This wireless video transmission system is also used on fire-fighting robots in China. Please see the video link. If you have any suggestions for our testing, or if you would like to see other testing methods, bizə müraciət edin.

I need a cofdm 4 Channel video transmission for the EOD (Explosive Ordnance Disposal) robot.

I recommend the best model of Vcan1935 is suitable. The full set of Vcan1935 includes one transmitter (support four-video camera, two-way data, iki tərəfli audio), one receiver (HDMI video receiver, two-way data, iki tərəfli audio), və 5 antenalar.

müştəri: I need it in the ground station box with the monitor and control software.

iVcan: Vcan1935 is a full set of video and data transmission systems between the EOT robot and the ground control station. (we don’t offer you the robot and ground control station. )

For the ground control station, please check the model of https://ivcan.com/p/robot-remote-control-handheld-wireless-video-transmitter/

The ground control station needs to be customized according to your demand. Misal üçün, the control platform of our fire fighting robot, in addition to the basic control buttons such as forward and backward, is more customized according to the needs of fire police customers by adjusting the angle of water spraying and controlling the amount of water.

We want to use your radios in our application involving one-way video and two-way data transmission.

Our deployment setup includes rugged laptops equipped with user interfaces and control algorithms tailored to our operational needs.

Software Integration for Radio Configuration: Our first requirement involves the capability to programmatically adjust the radio settings directly from our software. This is all user-configurable options detailed in your user manual, including but not limited to frequency, şifrələmə, and other pertinent settings. . Could you provide detailed documentation or an API that enable this level of integration?  I presume this is either a USB connection.

​At our Vcan1935, there are three ways to check and change the parameter.

1. On the serial software via the serial port
2. With RJ45 connection (type IP address to open web management system or use a serial software tool in Windows PC).
3. We also can offer you the private command set to change the parameter if you need built-in your software. Vcan1935 Communication protocol sample document

Data Transfer Specifications: The potential for data transfer via RS232/485 was mentioned. Does the system support full-duplex operations?

bəli, our video transmission is one-way from the transmitter to the receiver, and data and audio are two-way transmissions between the transmitter and receivers. ​Vcan1935 supports both R​S232/485 serial ports. They are full duplexes.

Compatible Camera Hardware: The types of cameras directly connectable to your device is required. We assume compatibility with IP or USB cameras; lakin, a precise definition of supported models or connection interfaces is needed.

​Support PAL/NTSC/AHD-1080P/AHD-720P ​camera

Video Reception on Laptops: On the receiver side, clarity on how the video feed is interfaced with our laptops is necessary. The documentation does not explicitly detail the method for connecting the received video feed to our systems. Could you specify the available options? Are the feeds accessible via USB, Ethernet, or another interface? 

​Support RTSP protocol or UDP method to obtain video data ​(ethernet RJ45 to PC)

The remote controller that you have developed:  I would like to know what is needed to consider using that device. Is it a windows machine? How would we develop our own application to use that device?

​The remote control is a Linux system, and the API is currently not open (made). The interface and functions need to be customized through consultation.

I need a 1.4 GHz video transceiver with IP-based. I will transmit 4 IP cameras concurrently. Distance will be maxed 200 m LOS, Bu model ikitərəfli simsiz məlumat bağlantısı ilə video və məlumatların simsiz ötürülməsi üçün nəzərdə tutulmuşdur. Environmental conditions will be -30, +50. Could you give me info about your product?

Sorğunuz üçün təşəkkür edirik. If you agree the camera is CVBS or AHD, then I will recommend vcan1935. As this model camera does not support IP-based cameras.

If you need a video transceiver with only four IP cameras, then I will recommend TX900 və ya Vcan1401.

Do you have a user manual for Vcan1935?

How many frequencies and antennae are at the transmitter?

The Vcan1935 supports one-way video transmission (frequency range 300Mhz-800Mhz ), two-way audio transmission, and two-way data transmission (frequency range 902Mhz-928Mhz). So there are two antenna at the transmitter.

From the transmitter to the receiver, the audio transmission is on the base of the video transmission. From the receiver to the transmitter, the audio transmission is on the base of the data transmission.
