Basic Functions and Performance of Spark M Type
Police speed sensors are specially designed for traffic police to monitor road speed.
Velocity sensors mounted on patrol vehicles can be measured in a moving or static manner. In the latter case, the speed sensor can be measured through the windshield or rear glass of the patrol car. The speed sensor can be used manually or automatically. Velocity sensors can also be installed on fixed objects. In static mode, speed sensors can provide the fastest target in traffic operation. In motion mode, the speed of the patrol car depends on the speed of following the target or your opposite target. Motion sensors can choose the direction of the target: following, reverse or moving. Motion sensors can provide the fastest target or the largest regional reflection target. (Maximum)
Sensor has no control device. It runs as a part of speed control system, and its control function and function, as well as information display function, are performed by means of additional devices: camera or platform. Exchange data with additional equipment can be transmitted to peripheral equipment associated with speed sensors (manufactured by other manufacturers) by means of RS-232 interface (buyer's choice) open data exchange protocol.
The power of the speed sensor is supplied by the automobile follow-up system or additional power supply.
The three-system method of signal processing can provide a unique recognition level, which can make the motion sensor of mobile patrol vehicle run steadily.
Signal processing method:
1. General mode: Used in the control system of patrol vehicle, it stipulates not only the fastest speed limit but also the maximum target speed limit. Under the movement mode, it ensures the maximum detection distance, reasonable speed and stable operation.
Fast mode: In static mode, it is used to determine the fastest and largest target. The measurement time is reduced by about half, and the distance is also reduced slightly.
3. Fast Zone Mode: In static mode, the measurement time can be shortened to the maximum extent. Only this method can determine the maximum target, but in this case, it is possible to simultaneously measure traffic moving in opposite direction.
Radar structural characteristics:
1. Unique weight (220 g) and size.
2. One of the world's smallest speed sensors.
3. Standard, widely applicable DB9 interface connecting COM-port (using data lines from other manufacturers).
4. Creative safety and convenient design.
5. The sensor shell is made of impact-resistant ABC plastic (brand NOVODUR).
6. Two kinds of fixing methods: movable-fixed with VELCRO belt and fixed-fixed with fixed screw.
The main functions and possibilities of radar:
1. Exchange data with external devices through two interfaces: USB or any of RS-232 (depending on the subscriber's choice).
2. The new method of calculating three modes of signal processing ensures the fast response and stable operation of the patrol vehicle in the moving state.
3. The working frequency is within K-range.
4. Choose the direction of motion: reverse, co-directional or all targets.
5. Velocity measurement in fixed mode and patrol vehicle motion mode.
6. Separate the fastest and/or most recent targets from the vehicle fleet.
7. Two values are obtained in one measurement, which can be used to evaluate the road condition in traffic flow more accurately.
8. Open communication protocol to connect other devices in radar and speed measurement systems.
9. Low energy consumption and wide range of speed measurement (10-300 km/h).
