Jcast Vehicle Detection System SC-100 User Manual - 3 - Introduction This guide provides information and procedures for installing Jcast Vehicle Detection Sensor Node(ORSN) SC-100 in conjunction with the Jcast Vehicle Detection System and ORSN Specifications.
Jcast Vehicle Detection System SC-100 User Manual - 4 - Overview In this section explains a Jcast Vehicle Detection Sensor, the contents of a Sensor Information and Sensor Specifications On Road Sensor Node (ORSN) SC-100 A Jcast On Road Sensor Node (ORSN) is a magnetometer capable of low-power radio communications packaged in a small, hardened plastic case suitable for in-pavement mounting. ORSN detect canges in the earth’s magnetic field to determine the presence or absence of vehicles relative to the detection zone of the ORSN. Detection “events” are transmitted via Wireless Communications to a Jcast Road Side GateWay(RSGW) where they processed, stored and forwarded to other systems(SUS). ORSN utilizes multifunctional sensors which consist of three-axis AMR, physical and pressure sensors listed in Tables I and II. The three-axis AMR is used for vehicle detection, classification and speed measurement while other sensors are used for calibration and enhancement of measurements.

Jcast Vehicle Detection System SC-100 User Manual - 8 - Installation Procedures This section discusses installation requirements and provides step-by-step installation procedures. Required Equipment Before installing a ORSN, ensure that the following components are available :  Jcast On Road Sensor Node(ORSN)(s)  A minimum of one tube of FJS epoxy for each ORSN A 2:1 ratio pack of Fablck Joint Seal(FJS), a two-component 100% solid silicone polyurea-based joint sealant is recommende. This self-leveling joint sealant displays fast cure times and excellent adhesion to concrete. In ambient temperatures from 20°F (-6.6°C) to 180°F (82.2°C) the epoxy cures in approximately five minutes.  Coring bit suitable for creating a hole (4” diameter, 2 ¼” depth [10.2 cm, 5.7 cm]) in the target surface Two types of 4-inch drill bits, each with 1¼” standard machine threaded sleeves, are recommended as shown in the following diagram.
Jcast Vehicle Detection System SC-100 User Manual - 9 - Coring bits For soft road surface, a 4” double cylinder coring bit is recommended. Once a 2” (5cm) deep hole is drilled, chisel any remaining material so that the result is a flat bottomed hole. For harder surfaces, a 4” grinding coring bit is recommended. Use a shop vacuum or other implement to ensure that the hole is free of all dust, debris and loose impediments.  Coring drill and frame  Cold chisel and club hammer or a power chisel  A shop vacunm, brush of other implement suitable for removing dust and debris from a hole cored in the oave ment  Heat gun propane torch (helpful in environments with significant roadway moisture)
Jcast Vehicle Detection System SC-100 User Manual - 10 - Step-by-Step Procedures Installing the Sensor/Shell Assembly into the Pavement 1. Find and mark the center of the desired ORSN location. 2. Core a hole approximately 4”(10cm) in diameter, and 2¼” (6 cm) deep into the pavement Check depth as your drill, remove debris periodically. Coring Sensor Hole 3. Vacuum or brush the hole clear of dust and debris Clearing Sensor Hole Ensure that the hole is dry as moisture may impede the curing of the epoxy. If moisture is observed, use the heat-gun or torch to dry the inside of the hole completely.

Place Sensor in hole. Verify the following  Label is visible  Arrow on label points in the direction of traffic flow 6. Fille the hole with epoxy, empletely covering the ORSN Filling Hole With Epoxy
