Trigger Radar

1.1 Installation
1.1.1 Install on bracket
The bracket of the trigger radar should be installed in the side road of the camera captured position( which is far away from camera straight line 4meters, and the vertical distance 0.5~0.7meters from the lane lines.)
Compare the mounting holes of the radar support column, drill 3 holes 50mm deep on the ground with the M6 drill bit, and then fix the support column on the ground with 3pcs M6 expansion screws, as shown in figure 1.

At a height of 600mm ~ 800mm from the road surface (not guard room table), fix the radar backside on the support column with 4pcs flange screws, and then fix the radar backside with 4pcs M4 screws. The radar wire harness and the protective wire sleeve are threaded into the column through the nearest round hole, as shown in figure 2.

Final installation like figure 3,

1.1.2 Install on gate box
Slotting a hole with a diameter of 13mm at a position 600 ~ 800mm above the ground on the barrier gate box (the center line of the same direction as the gate arm). show as picture 8.
Notice: It is recommended to apply glass glue around the contact surface between the radar shell and the barrier gate box to prevent rainwater from infiltrating into the box.

Put the communication cable through the round hole into the barrier gate box, and then use the PG connector nut to lock it. See figure 5.

Final installation like figure 6,

Notice：

1. Make sure the barrier gate box and radar sensor is install fastness, otherwise, it will influence radar detection accuracy if the barrier gate box and radar sensor is shaking.
2. Don’t put any objects in the radar detection area.
3. Install the fence out of the radar detection area, try not move around as much as possible.
4. Please calibrate radar sensor soon after situation is changed.
5. Don’t calibrate radar sensor in rain and snow condition.
6. When the vehicle passes through the anti-hit area, the greater the angle between the vehicle and the road, the worse the radar detection performance will be. We suggest use the radar in a situation which the angle is less than 30 degree when driving.

Light goes off when there is no object be detected(or object left)

Table 2 Indicator light definition and description

1.4 Automatic calibration
Press the button of the end line of the radar cable with 1 second and then loosen, radar will automatically update the background threshold, the green light will flash 4 seconds during the recording period, when the light stops lighting means update the background threshold succeed.
Please assure there is no object pass by within the radar detection range for 4 seconds.

1.5 Parameter setting
The radar sensor’s default detection range(meter) and gate arm fall time(second) is show as figure 3.

Table 3 The default parameter table of the trigger radar sensor

1.6 Check the statue of Radar Sensor
First of all, human enter into the radar detection area, the radar green light OFF, the barrier gate camera doesn’t snap, the gate arm not up.
Second, vehicle enter into the radar detection area, the radar green light ON, the barrier gate camera is snapping, the gate arm up.
Third, vehicle enter into the radar detection area with the speed of <10km/h, the radar green light always ON, the camera doesn’t shoot continuously.
Finally, vehicle enter into the radar detection area with different speed of 0~30km/h, contrast the camera’s snap position, it will be <0.5meters difference.

Anti-hit Radar Sensor

2.1 Installation
Slotting a hole with a diameter of 13mm at a position 600 ~ 800mm above the ground on the barrier gate box (the center line of the same direction as the gate arm). show as picture 8.
Notice: It is recommended to apply glass glue around the contact surface between the radar shell and the barrier gate box to prevent rainwater from infiltrating into the box.

Put the communication cable through the round hole into the barrier gate box, and then use the PG connector nut to lock it. See figure 9.

Final installation like picture 10 and picture 11:

Notice：

1. Make sure the barrier gate box and radar sensor is install fastness, otherwise, it will influence radar detection accuracy if the barrier gate box and radar sensor is shaking.
2. Don’t put any objects in the radar detection area.
3. Install the fence out of the radar detection area, try not move around as much as possible.
4. Please calibrate radar sensor soon after situation is changed.
5. Don’t calibrate radar sensor in rain and snow condition.
6. When the vehicle passes through the anti-hit area, the greater the angle between the vehicle and the road, the worse the radar detection performance will be. We suggest use the radar in a situation which the angle is less than 30 degree when driving.

2.6 Check the statue of Radar Sensor

1. Function test for human and vehicle distinction:
   First of all, raise the barrier gate arm, human enter into the radar detection area, the green light of the radar sensor is OFF, after human is left the radar detection area, the barrier gate arm is not down;
   Then, raise the barrier gate arm, vehicle enter into the radar detection area, the green light of the radar sensor is ON, after vehicle is left the radar detection area, the barrier gate arm is down.

2. Function test for vehicle anti-hit:
   First of all, raise the barrier gate arm, the vehicle pass under the barrier gate arm at the speed of 10km/h, the radar sensor light is always ON when vehicle is under the gate arm, and the gate arm don’t shake and don’t hit the vehicle.

3. Function test for human anti-hit：
   First of all, after the vehicle is gone, human is passing by under the gate arm during the gate arm down period. At this time, the radar sensor light is ON, the barrier gate arm up and don’t hit human;
   Then, human is moving forward and backward in the horizontal direction of the gate arm, the radar sensor light is always ON, the gate arm is not down and don’t hit human.

Maintenance and common failure predication

Radar has the characteristics of high technical content and strong professionalism. Please read the product operation manual and relevant documents carefully before use.

1. Caution

1. The power supply voltage should be appropriate, not too high or too low, so as not to affect the radar performance;
2. Don’t cover the radar front;
3. Don’t plug the serial port;
4. Avoid impact and drop, so as not to damage the product.

2. Common failure predication

1. The test management software can’t be connected
   Check whether the power supply is connected properly, whether the serial port is connected securely, and whether the line sequence is correct. Check whether the serial cable and converter is damage.
2. Can’t detect the object
   Open the test management software to read the configuration information and check whether the parameters are read correctly: if there is no change, there is a problem with the serial connection. Please make sure the serial connection is normal and the serial parameters are configured correctly.
   If the detection state remains unchanged, the radar needs to be re-calibrated and please ensure that there are no targets within the radar detection area.
3. Radar unresponsive when human passes
   Open the test management software to read the radar configuration information and check whether the human and vehicles distinction function is on, if YES, change it to NO and save the parameters.
4. The barrier gate arm can’t down after the vehicle is pass
   Open the test management software to read the radar configuration information and check whether the detection distance setting exceeds the actual lane width. If so, it is required to change according to the detection distance setting table and save the parameters(Notice ： the detection distance has to be set less than the actual lane width)
5. Radar sensor green light always ON
   Check whether there is any change in the surrounding environment background. For example, if the position of the surrounding lane fence changes, if yes, the background threshold should be renewed (Notice：don’t update background threshold in snow and rain condition).
   Please take attention that changes or modification not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
