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.

ME9300 system consists of DSRC antenna ME9301, Interface Box ME9302 and Dedicated I/F cable ME9303.
ME9301 communicates with OBE installed in the vehicle and reads the WCN of OBE. This read WCN is transmitted to ME9302 via the cable ME9303 with a maximum length of 100 m.

ME9301 communicates with OBE installed in the vehicle and reads the WCN of OBE. This read WCN is transmitted to ME9302 via the cable ME9303 with a maximum length of 100 m.
ME9302 compares the read WCN with the WCN registered in ME9302 in advance. Meanwhile, since ME9302 has the digital input DI (maximum 6 inputs), the digital output DO (maximum 6 outputs) will be decided from these DI information and coincidence/difference of WCNs (the read WCN is coincident with/different from the read WCN registered).
In addition, ME9302 has LAN and RS-232C as interfaces for communication with external networks and external devices. Either LAN or RS-232C should be preselected at the factory shipment. However, it can be changed at a later date.

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.
