Notes

• WCN（Wireless Call Number）
  WCN is a 12-digit unique number attached to each OBE. In other words, the vehicle can be dentified by WCN.
• DSRC（Dedicated Short Range Communication）
  DSRC is the name of wireless communication technology. One application of DSRC technology is ETC used on highway.

System configuration

ME9300 system consists of DSRC antenna ME9301/ME9301V, Interface Box ME9302 and Dedicated I/F cable ME9303.

Features

Various services to vehicles installing registered WCN will be provided.

It communicates with the OBE installed in the vehicle to read WCN and it’s checked whether the read WCN coincides with the registered WCN.
Digital output DO is determined from digital input DI and coincidence/difference of WCN.

Equipped with digital input DI and digital output DO.

Input format of DI is photo coupler and output format of DO is photo MOS relay, and 6 inputs and 6 outputs are equipped with.

Dedicated I/F cable of 100m maximum

The length of Dedicated I/F cable ME9303 connected to DSRC antenna ME9301 is 100m maximum.

Maximum number of WCN registrations of 160,000

The maximum number of WCN registrations that can be registered in Interface Box ME9392 is 16,000.

With preparatory function for providing various services

With ME9300 control software MAS930 on the PC, "Sequence setting" is performed according to the scenario of processing.
The WCN of the vehicle is read using DSRC communication unit ME9115A/A+C and it’s registered in ME9302 in advance.

Capable of communication with external devices.

Interface Box ME9302 has LAN and RS-232C as interfaces for communicating with external devices.

It’s also possible to transfer the read WCN directly to the external device.

It’s also possible to transfer that data to the external device after communicating with the ETC OBE to read WCN. In this case, pre-registration of WCN is unnecessary.

ME9301V can adjust the transmission power

The ME9301 has a fixed transmission power of 5mW.
The ME9301V can change the transmission power in the range of 0.2 to 1.25mW(8dB variable width).

ME9300 system application examples

Parking lot management

If it’s installed at the entrance/exit point of the parking lot, the gate opens automatically when a registered vehicle comes close. Passing only permitted vehicles will be a security measure.

Area entrance vehicle management

The admission of vehicles non-registered will be restricted at disaster areas and construction sites. Prevent entry of unnecessary vehicles so that prevent traffic jams or confusion at the site.

Traffic congestion survey

The WCN of vehicles traveling on highways and national roads are detected at two points and the time between two points and traffic jam will be estimated from the passing time of the same vehicle.

Vehicle movement management

It’s installed in major places in vast factory and automatically records passing vehicles. This allows to grasp the movement of the vehicle in the factory.
