Vehicle detector ND-1000

Vehicle Detector Model: ND-1000 Instrument: I. Introduction vehicle traveling speed detector is passing motor vehicles, traffic, road share of special test equipment. Product data processing system using quasi-military-grade embedded single board computers, 64M electronic processing module is mainly responsible for all signals from the detector card AS-241 is collected and processed. Communication is also responsible for monitoring the state of the system and with external devices. Detecting amplification system uses Ascentech boards, stable and reliable product quality, the detection module AS-241 is a four-channel induction coil test card, is responsible for collecting the toroidal coil inductance changes, and output to the processing module. 4-channel fully operational independence, not only to detect high precision and excellent crosstalk prevention function. And it has a high price; Ethernet, RS485 / RS232 communication mode communication control unit using a common, easy to install, especially for system integration. The series uses the anti-jamming design, enabling the system to normal operation in strong interference environment, to ensure detection accuracy. The detector box dimensions of 500 (W) × 450 (depth) × 650 (high). Door rubber seal waterproof; open to the police. The products in the off state by the battery (optional) power supply around the clock to ensure the detector uninterrupted work. Applicable to all forms of roads, tunnels, bridges, urban transport. Second, the vehicle detector function: a, each detector channel can reliably detect any vehicle, multi-axis, high vehicle body and trailer on the highway as a vehicle testing. Detector coil processing section matches and to prevent erroneous detection neighboring lane vehicles. b, the detector system can provide the following traffic parameters: a number of vehicle lanes, vehicle speed, vehicle occupancy (per lane car, carts, trailers are counted separately). c, the detector having a predetermined processing function, for the detection of the traffic parameters, can by 10 seconds, 30 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes, 1 hour and other period (this period can be reset) accumulated . d, the detector has a memory function that can store seven days of the test data, has two RS232 ports, can input data to a central computer and local maintenance terminal. e, vehicle detector sampling time traffic parameters can be set, you can adjust the sensitivity of the detector. f, detector panel indicates whether the machine is working properly displayed, the key parts of the abnormal reaction shows that each lane detection plate output is normal display. g, the detector count passing vehicles analog functions to facilitate commissioning and maintenance. h, the detector military design, continuous uninterrupted work. i, the detector has a self-test / troubleshooting feature that can provide processor machine and coil operating state information, available on the processor panel lights display (vehicle detector operating states: normal, alarm, communication fault) and It can be transmitted to the monitoring center computer system. j, detector power recovery (or reset) automatically return to normal state after 30 seconds, the original stored data remains unchanged k, when the same car in two adjacent coils on the two-lane, processor logic to identify line analysis and processing, to produce the corresponding signals and detect only one lane information l, vehicle detector can be set to a variety of coil oscillation frequency, so that the same chassis to minimize crosstalk m, vehicle detector with remote setting and remote reset capability performance Parameters: a 8-12 channel detection ports for 4-6 lane traffic parameter detection; (expandable to 16 lanes) communication uses RS232 standard interface, transfer rate: 4.8 ~ 19.2kbps. Optional hardware (on this basis can choose a variety of telecommunication components); communication protocols: RS232, RS422, RS485, V.24; detection probe sensitivity range: from 0.01% to 1.28%, the seven-speed sensitivity selection; detection probe adaptation Inductance range: 10 ~ 2000μH; vehicle false detection rate: ≤1%; (two-wheel motor vehicles of all types over large motorcycle); and speed range: 0 ~ 250Km / h; detection cycle: 15 seconds to 60 seconds adjustable; vehicle speed detection accuracy of detection accuracy: ≥97% traffic detection accuracy: ≥99% share in detection accuracy: ≥98% Power supply: 220VAC ± 20%, 50Hz ± 5Hz; power consumption: <200W Operating temperature: -20 ℃ ~ + 65 ℃, -40 ℃ ~ + 80 ℃ two specifications available; equipment MTBF MTBF: more than 40,000 hours; electrical pulse interference protection and electrostatic interference protective devices meet these IEC801-Ⅱ3 grade severity, shell protection grade IP65-IP66 two sizes optional equipment power input and signal input terminal have good lightning protection measures.
