Set up the column:
An antenna mounting pole with a diameter of ø50-120 mm and a length of 1.8 m, preferably made of stainless steel with a wall thickness of more than 1.2 mm, is to be erected on the barrier island at the entrance to the car park. The position of the antenna mounting pole on the barrier island is shown in the figure below.
Mounting the antenna:
Secure the microwave antenna to the top of the riser with the fasteners supplied in the antenna box, the distance from the centre of the antenna to the level of the driveway is about 1.5-2.0m.
Adjust the angle of the antenna, the antenna pitch angle refers to the angle between the antenna tilted towards the ground and the riser pole, about 20~25°.
Install the antenna:
Keep the antenna connector facing down to prevent it from getting wet from rain and seal it with waterproof tape if necessary.
Antenna azimuth angle, refers to the offset angle of the antenna towards the direction of the lane, about 30~40°.
Note: The above installation dimensions are designed for a lane width of 3.0 metres, and should be adjusted appropriately for specific lane conditions in actual application.
In order to solve the problem that behind a car which has affixed the long-distance range card opens the gate for a car which has not installed the long-distance range card in front, designs the antenna installment method, does not request reads the electronic label the distance farthest, but lets the vehicle close to the antenna can read the label, goes to opens the gate.
Antenna side-mounted:
The direction of polarisation is kept the same between the card and the antenna;
The trajectory of the card must pass through the centre axis of the information field to the maximum extent possible;
For optimal system performance, the card is kept as parallel as possible to the reader as it passes through the information field.
Antenna top mounting:
1. the direction of polarisation between the card and the antenna remains the same;
2. the trajectory of the card must pass through the centre axis of the information field to the maximum extent possible;
3. In order for the system to achieve optimum performance, the tag should remain as parallel as possible to the reader as it passes through the information field;
4. Take care to determine the height of the reader;
5. Pay attention to the card through the information field when the card and the information field axis line angle.
Installation of the reader:
The reader is installed in the lower part of the ‘manual card spitting machine’, due to the different specifications of the card spitting machine produced by each manufacturer, so how to install the reader into the card spitting machine, the system integrator is responsible for solving.
As the length of the microwave cable connecting the reader and the antenna is 3.0 metres, the installation of the reader should be considered to facilitate the connection of the cable.
Note: The reader and the microwave antenna are connected by a low-loss high-frequency cable, and it is recommended that the cable length be as short as possible, with the maximum length not exceeding 10m.
8、Electronic tag/card installation
The card can be mounted on the inside of the car windscreen using a card holder. And keep the card facing the reader.
The best position for the card to be placed in the windscreen of the car: B, at the rear view mirror of the window.
Considering the actual situation of the project, the card can also be placed in other positions such as A, E, C, D, and so on. When placing the card in other positions, it must be kept at a distance of 8cm from the car’s side frame.
Note: Some cars have windscreens with metallic anti-explosion film, which can cause the reader to be unable to read the card.
Original with anti-ultraviolet film front windscreen: according to European standards, the front windscreen upper rear-view mirror behind the position (B position), the car manufacturer will set aside a 120mm long, 70mm wide, metal ion-free components of the bare glass window exclusively for the electronic tag with the installation of the label can be installed as long as the label is installed in this.
After the installation of anti-ultraviolet film mounted on the front windscreen: the installation of the label, you can be in a more hidden position (such as B, E, D position) will be cut out of the anti-ultraviolet film length of 120mm, width of 70mm of the bare glass window exclusively for the use of electronic tags.
9、Installation case: one in one out
Vehicle speed is below 15km/h:
Entrance and exit without intermediate isolation of the security island, road gates and other equipment installed on both sides of the road, the speed of vehicles entering and exiting requires 0 to 15 km / h into the card reading area.
In this case, the reader antenna (or integrated reader) is required to be installed close to the road gate equipment, and at the same time, the reader should be adjusted to effectively read the tag card range to be able to cover the position of the vehicle ground sensing coils of the inlet and outlet transmitter position (the distance between the antenna and the transmitter is about 1 to 3M).
Vehicle speeds of 15 kilometres per hour or more:
Entrance and exit without intermediate isolation of the security island, road gates and other equipment installed on both sides of the road, in and out of the vehicle speed requirements in the 15 ~ 30 km / h into the card reading area.
This case requires the reader antenna (or integrated reader) from the road gate equipment 1 ~ 2M or so installed, at the same time should be read to read the reader effectively read the tag card range needs to be adjusted to cover the entry and exit card issuer position of the vehicle ground sensing coil position (antenna and the distance between the card issuer in the 2 ~ 3M or so).
Note: In the same system, if the read-write reading fails to reach the normal reading distance or the reading performance is weakened, it is necessary to set the read-write to a different RF channel. At this time, you need to open the reader setup software, according to the site environment to find the best reading channel.
10、Understanding antennas
Note: The antenna is an important part to realise the reading distance and reading range, mastering the performance of the antenna plays a decisive role in the final effect achieved by the project.
If the card is tilted at an angle of 45º with respect to the centre axis, the range will be attenuated by about 30%.
Therefore, in the engineering design/construction, the antenna height up/down and angle left/right are adjusted by predicting the direction of the vehicle travelling, so that the line of travel of the vehicle and the card passes through the central axis as much as possible.
11、Installation cases：Access control
The reader is mounted invisibly. The reader is mounted on the ceiling in any direction that the card is orientated.
Review-Precautions ＞
1. When the antenna is not connected to the reader, the reader cannot be energised;
2. The feeder cable used to connect the antenna and the reader, the maximum connection length is 10 m. The standard configuration of the equipment is 3 m, please try to control it within 3 m during the engineering design/construction;
3. The antenna is an important component to achieve the reading distance and reading range, master the performance of the antenna, the final effect of the project to achieve a decisive role;
4. Must consider the tag through the information field, the front of the tag and the information field axis of the angle caused by the reading distance attenuation;
5. Card and antenna between the existence of polarisation direction, card and antenna in the same polarisation direction is the farthest reading distance. Card and antenna in different polarisation direction is also can read the card, but the distance is very close. At this time, just rotate the card by 90 degrees;
6. When installing the antenna, the feeder connector of the antenna must be facing down;
7. There are some cars with metal anti-explosion film attached to the windscreen, which will cause the reader to be unable to read the card, so you need to cut off part of the anti-explosion film;
8. For wiring, it is best to bury the power line and signal line in separate pipes;
9. In the multi-lane installation, read-write reading does not reach the normal reading distance or reading performance is weakened, the need to read-write set to a different radio frequency channel. At this time you need to open the reader setup software, according to the site environment to find the best reading channel.
