It provides timely and effective warnings of the proximity of dangerous vehicles approaching a school bus. TechSols Inc.2586 Carp Rd. Ottawa, ON.

(CLZ), and Braking Zone. Mounting Offset (MO):The distance is from the radar installation position to the front edge of the bus for the front radar, or the distance is from the radar installation position to the rear edge of the bus for rear radar. Safety Zone(SZ):The distance is from stop line to the front edge of the bus, for front radar. The distance of stop line to the rear edge of the bus, for rear radar. Clearance Zone (CLZ): CLZ is defined to avoid near-distance noise interfere. This setting is important to eliminate false alarms in hostile weather conditions, such as heavy rain. Braking Zone: The area in front of the stop line. TechSols Inc.2586 Carp Rd. Ottawa, ON. K0A 1L0 Canada Tel:613 435 2292 Fax: 613 435 2846 www.techsols1.com 2.2 Alert trigger conditions 2.2.1 The target(s) within braking zone The braking curve of a car approximates a parabola. Fig.3: Alert trigger conditions The radar measures the distance D1 and velocity V of the target. The built-in program calculates the required braking distance D2 for the target by the formula D2=kV2. We define the parameter ALATPC asalarm parabola coefficient k(ALATPC is not a real K. The built-in program converts ALATPC to K. Here, the user can approximate that ALATPC is equal to the braking distance that the target speed from 100km/h--0km/h), the parameter WARADM as warning parabolic adjustment value. a, If D2>D1, radar outputs alarm. b, If D1>= D2>D1- WARADM, radar outputs warning. TechSols Inc.2586 Carp Rd. Ottawa, ON. K0A 1L0 Canada Tel:613 435 2292 Fax: 613 435 2846 www.techsols1.com 2.2.2 The target(s) within the safety zone or mounting offset zone Since the car is not allowed in this range, the violation and alarm will be triggered as soon as the target speed is found to be greater than 15km/h. This speed threshold is based on the exclusion of pedestrians and other situations in this area. 2.2.3 Heartbeat and Health check If the radar is available, it sends a heartbeat ($READY) every 5 seconds. The client also can send a health check message (@RADAR \r\n) to check the radar status when the timer expires. If the system status is normal, the system will reply $READY, otherwise the system will reply $RADARINOP. 2.3 Intelligent rainfall judgment Radar can use algorithms to determine the intensity of rainfall and change its configuration parameters in real time. The algorithm allows the radar to work in extreme weather conditions and improve alert accuracy. If there is no rain or light rain, CLZ will be modified to 6m and VIO will be modified to 15Km/h. If there is moderate rain, CLZ will be modified to 10m and VIO will be modified to 15Km/h. If there is heavy rain, CLZ will be modified to 10m and VIO will be modified to 35Km/h.

Violation works independently, but Violation will trigger Alarm. For example:
1. If the system detects Alarm, Warning, Violation at the same time, it will output Alarm and Violation. 2. If the system detects Alarm, Violation at the same time, it will output Alarm, Violation. 3. If the system detects Warning, Violation at the same time, it will output Alarm, Violation. 4.If the system detects Alarm, Warning at the same time, it will output Alarm. 5. If the system only detects Alarm, it will output Alarm. 6.If the system only detects Warning, it will output Warning. 7. If the system only detects Violation, it will output Alarm and Violation. 2.5 LOG output control Radar output of large amounts of data is a burden for the radar and not useful to the customer. This radar allows customers to change LOG output rules. The default LOGMODE = 0: the radar only outputs heartbeat. If LOGMODE = 1, the radar outputs heartbeat and detected data. If LOGMODE = 2, the radar outputs heartbeat and alarm. If LOGMODE = 3, the radar outputs heartbeat and detected raw data and alarm. TechSols Inc.2586 Carp Rd. Ottawa, ON.
