ETC / ITS spot electric field strength measurement system ME9200
- With this system, after measuring the electric field strength distribution of the ETC/ITS spot with operation wave or CW wave in a short time, the electric field strength graph and the map diagram are created.
- The price is inexpensiveness
- the electric field strength measurement function of the ITS spot
- Automatically measure while driving.
It is possible to measure by handcart or by in-vehicle, and the price of ETC measurement system (9 antennas) is inexpensive.
Optionally, the electric field strength measurement function of the ITS spot can be added.
When measuring the plural roadside units on the main line, the measurement is automatically performed even while driving according to the positions of the measurement section and measurement conditions registered in advance if the automatic measurement mode is used.
When equipping handcart type with17 antennas, the lane of 3.2 m width can be measured at a time.
The standard type consists of 9 antennas and the lane of 3.2m width can be measured at two times. <Antenna interval 20cm> The number of antennas can be increased up to 17 units. In addition, using a single antenna, the transmission frequency and power of the roadside unit outputting CW wave can be measured.
Outside domensions:138(W)×30(D)×101(H)mm (excluding projections)
Since the speed sensor is equipped, the measurement distance is automatically calculated. When 17units of antennas are attached, the lane of 3.2 m width can be measured at one time. The ground height of antenna can be set to 1m or 2m.
Outside domensions:700(W)×1000(D)×350(H)mm (when folding)
Outside domensions:700(W)×1000(D)×900(H)mm (when assembled)
The start switch and the switch to adjust position of roadside unit to zero point are equipped. When measuring by in-vehicle, the distance is calculated by taking in the vehicle speed pulse of the car. Power supply of 12 VDC is required.
Outside domensions:430(W)×450(D)×101(H)mm (excluding projections)
It controls the control unit and immediately displays the measured electric field strength as a graph or map diagram. The automatic measurement mode can be used to measure the electric field strength of the plural roadside units on the main line. This means the labor saving because it's possible to measure without operating at each point while traveling by registering the spots "kilo-post" of multiple measurement sections and the measurement conditions beforehand.
Electric field strength measurement method
[Measurement by handcart]
Measure the electric field strength distribution of the roadside unit installed on the ETC gate of the highway accurately and in short time with the CW wave or the operation wave.
[Measurement by in-vehicle]
The electric field strength distribution of the roadside unit installed on ETC gate, main line or ITS spot on the highway can be easily measured with the operation wave while traveling by normal speed (100 km / h or less).
Electric field strength measurement example
The software of ME 9200 operating on PC controls the control unit and performs the measurement, and further collects, analyzes and displays the data automatically.
Example1 [ Electric field strength measurement by handcart ]
- The measurement can be performed in detail at ETC tollgate.
Example 2 [ Electric field strength measurement by in-vehicle ]
- The measurement can be easily performed at ETC tollgate.
- The measurement can be performed while traveling by less than 100 km / h at ETC notice antenna or ETC free flow where it's difficult to stop.
Example 3 [ Electric field strength measurement at ITS spot by in-vehicle ]
- The measurement can be easily performed while traveling by normal speed on a highway.
- The measurement can be performed by slowing down or stopping at ITS spot in a highway service area.
