Common faults in the installation and use of parking lot barrier radar

In large-angle (over 30 degrees) turning scenarios such as large vehicle logistics parks, the left and right detection ranges are adjusted to more than 1m or lane guide cones are added to guide vehicles to drive in the direction perpendicular to the radar illumination.

How to debug the radar when used in telescopic doors or sliding doors

A radar needs to be installed on each side of the door, 50-60cm away from the telescopic door or sliding door. The detection range of the radar close to the door is set to 0.1m, and the detection range of the other side without the door is set to 0.5-1m according to the actual situation on site.

Is the radar set to differentiate between people and vehicles, or does it detect people?

The radar has a default delay of 6 seconds for distinguishing between pedestrians and vehicles, that is, within 6 seconds after the green light of the radar goes out, a person can trigger the radar. This is to avoid pedestrians following the vehicle and hitting the vehicle or people. Therefore, during the test, you need to wait for 6 seconds after the green light of the radar goes out before triggering the radar test.

How to install radar for advertising pole scene?

Mixed-in and mixed-out scene settings: a radar on each side of the pole, with a height of 65-80cm.

Single-channel scene setting: It must be installed in the direction of the oncoming vehicle. The car passes the radar first and then the pole to ensure timely and stable detection.

02 Common radar problems: connection

Why can't I select the trigger mode after connecting to the radar?

Anti-smash radar can only select anti-smash mode, and trigger radar can select trigger mode; anti-smash radar and trigger radar are two models, anti-smash radar cannot select trigger mode, and trigger radar cannot select anti-smash mode.

Cannot search Bluetooth, and the Bluetooth connection is unstable?

The effective connection range of radar Bluetooth is about 1 meter. Try to get close to the radar when connecting to it, otherwise it may not be searched or the connection may be unstable and easy to disconnect. The radar can only be connected to one device. When reconnecting, you need to disconnect the current connection before connecting to another device; power off and restart can force the radar to disconnect from the current device.

After entering the password, the connection fails and the message "Operation timed out" appears after entering the password again?

If the power supply is unstable, this may cause this situation. First check whether it is caused by unstable wiring or poor contact. If the power supply is unstable, the radar green light may flash or the radar green light may be always on after power-on.

03 Common radar problems: rod drop/rod ejection

The radar light is always green, and the pole will not fall?

First, check whether the radar is installed properly; secondly, check whether there are license plate recognition, telescopic doors, other metal objects or ground protrusions within the radar detection range that affect radar detection. If so, move the objects that affect radar detection away, modify the radar parameters appropriately, and adjust the radar installation position. Parameter debugging: Check the radar log or display the virtual scene function, check the coordinate position inside, and then optimize the distance parameters.

Sometimes a car passes by without the barrier lowering, but it can be lowered using the remote control, or another car passes by but it will lower?

The radar is set to distinguish between people and vehicles, and the sensitivity is too low. It is recommended to set the radar to distinguish between electric vehicles, which can also distinguish between people and vehicles and has higher sensitivity.

What is the false alarm displayed in the APP? What scenarios are they generally used for?

It is mainly used after radar debugging. If the radar green light is always on, you can display the false alarm to see the distance and position information of the target in front of the radar to confirm the reason why the radar is always on. If there is no real object, you can eliminate the radar false alarm.

It takes a long time for the barrier to drop after the car passes. Is there a delay in the radar?

First, check the time when the radar green light goes out after the car passes. The radar green light and the signal are generally synchronized. If the radar green light is still on after the car has gone a long way, it is a radar problem. The reason may be that the radar is installed at a low height, and the radar will detect the weak target false alarm point on the ground, resulting in a delay. Slightly raising the installation height of the radar (no more than 85cm) can solve the problem; if the green light goes out quickly after the car leaves, but the gate does not drop, you need to check the gate problem.

The straight rod rises and falls repeatedly, and there is a rod bounce phenomenon?

Possible reasons: The billboard is hung on a straight pole, or there is a telescopic joint;

Setting method: When saving parameters, click "Yes" and select the straight pole direction. After learning, eliminate false alarms. For details, refer to the document "Unconventional Straight Pole Scenario Radar Debugging Method".

The fence posts rise and fall repeatedly, bounce up and fall down repeatedly?

Possible cause: The pole was detected.

Solution: Relearn the background or seek remote debugging.

On rainy days, the straight pole is repeatedly raised and lowered, or the pole is lowered immediately after being raised. Is this normal on sunny days?
