1、A list ITS-A08 is a set of system developed by Changsha Mozhibi Intelligent Technology Co., Ltd. for forward collision warning FCW, which gives early warning to dangerous targets in the lane directly ahead. Its unique ability to penetrate smoke, fog, and dust is available for allday, all-weather applications. ITS-A08 can detect targets as far as 80M. The alarm type includes 485 communication and IO level output.
2. Product features ⚫ spectrum: 77-81G ⚫ appearance size: 107.5 * 73.2 * 18 mm ⚫ waterproof level: IP67 FIG. 2.1 Dimension drawing Remark: Unmarked dimensional tolerance: When ≤10mm, the tolerance is ±0.3mm;When between (10~50) mm, the tolerance is ±0.5mm;When ≥50mm, the tolerance is ±0.8mm.
3. Product parameters The ITS-A08 radar adopts the FMCW modulation mode with high complexity, and is accurate in the measurement range determine the coordinates and velocity of the target relative to the radar. Table 3.1 ItS-A08 Performance parameters features System property Detection performance Communication interface parameter Technical indicators Working voltage 9-24V Working temperature - 40 ℃ ~ 85 ℃ Power consumption < 2.5 W.
4. Product functions 4.1 Longitudinal stationary target recognition The self-propelled vehicle moves forward at a constant speed in the center of the lane towards a stationary vehicle. The self-propelled vehicle starts one within a safe distance Level 2 alert. Activate level 2 within a critical distance. Figure 4.1 Static target recognition 4.
The self-propelled vehicle and the target vehicle travel at the same speed in the center of the lane, and the vehicle in front of the adjacent lane slows down to a speed significantly lower than that of the self-propelled vehicle and the target vehicle in front; No alarm will be issued during overtaking. Figure 4.3 Lateral target identification 4.
4.5 Interference recognition in adjacent areas (1) According to the regulation of road clearance height in 2.0.7 of JTG B01-2014, the clearance height is 4.5m, and no alarm will be issued if the self-propelled vehicle drives under the target with a height of 4.
6. Quick Use guide 6.1 Pin definition Stitch definition and interface cable description are shown in Table 5.1.
FIG. 6.2 Radar installation diagram 6.3 Output Agreement Radar has two warning modes, one is IO output warning mode, the other is 485 output warning mode. IO port output mode Radar warning protocol: In IO port output mode, the radar warning information is composed of warning lights and buzzers, and the warning level is determined by TTC (collision time, unit second) and absolute distance threshold L1 (unit meter). L1 is the range threshold detected by radar.

To save the Settings. 6.3.2 Radar boot self-test The radar will conduct self-check at startup. If the radar output mode is IO port output mode, the buzzer and the early-warning light will work twice at the same time at startup.
