Product Details

Vehicle weighing systems static truck scale, its weighing accuracy can reach the national level Ⅲ standard, fully meet the national standard of measurement commerce, to meet the plan need to re-charge system, vehicle weighing system and design the axle load detection, driving directions and traffic lights to guide indicates that the vehicle is determined through balance and other functions, can meet the technical requirements of the highway toll by weight.

Static Truck choose larger tonnage, countertops longer scale body to meet the weighing needs of most vehicles, vehicles for special long, can weigh several segmentation method to complete the vehicle weighing.

Use the tread plate scales countertops to prevent skidding or because the weighing platform surface ice to lose control of the vehicle.

Vehicle weighing system consists of a static truck scale, axle recognition, infrared vehicles separator, traffic light indicator and control cabinets and other components.

Vehicle weighing system capable of static and low-speed vehicle weighing adopted, can detect the number of axes, axle load and vehicle weight of the vehicle, the vehicle can be accurately separated vehicle weighing information can be detected by specified protocol send first bit machine, for not fully reverse or incomplete entry vehicle, the system can correctly judge handling vehicles weighing data. Scales table used tire tread plate rolling position to prevent skidding or because the weighing platform surface ice surface of the vehicle out of control.

⑴, weighing platform

Rated load: 180 tons

Weighing Accuracy: GB (Ⅲ) level

Sensor Rated capacity: 40t;

Maximum Security overload: ≥125% F.S;

Output Sensitivity: 2 ± 0.002mV / V

For pavement slope aspect: ≤2%;

Basic form: shallow pit type

Working temperature: -20 ℃ ~ + 60 ℃

Humidity: ≦ 95%

Equipment Protection Level: control devices: IP65; weighing sensors: IP68

Weighing station anti-corrosion strong, both buried in the underground part of or exposed parts can prevent corrosion, especially salt spray and motor vehicle emissions.

⑵, axis identifier

①, using pressure sensor, single sensor payloads ≥5t,

②, the vehicle identification number of axes, axle load, driving direction and speed, with the weighing station to provide data communication interface to the system;

③, with a self-diagnostic function, when the shaft identification fails, the fault can send information via hardware and software;

④, the working environment: temperature: -20 ℃ ~ + 75 ℃; Relative humidity: 0 ~ 95% RH;

⑤, protection class: IP67; life of more than 8 years;.

⑶, infrared vehicles separator

①, using infrared light curtains and high-energy, high transmittance photoelectric cells, infrared emission tube length is 1100mm;

②, can distinguish the vehicle from the ground up height: ≤1500mm, minimum height from the ground: ≥400mm; within this range, the minimum resolution size is not greater than 50mm; the minimum distance separable two vehicles is not more than 200mm;

③, in good weather, separate determine the correct rate ≥99.5%, in bad weather, separate determine the correct rate of more than 98%;

④, with electrical heating the glass and temperature control device, can automatically clear the surface condensation, frost or fog;

⑤, with a self-diagnostic function, when the separator failure, can send information via hardware and software fault; when the sludge, excessive dust or photocell fault on the windows, you can automatically detect faults, and ignore or block have beam problem, still work, while the output alarm signal when troubleshooting can automatically return to work status;

⑥, in harsh environments, such as: light interference, rain, snow, fog, temperature anomalies, able to ensure reliable operation, and ignore the interference of snow, stones, such as insects or birds;

⑦, scanning time: each beam 50μs, the processing time is 200μs, beam spacing 19.1mm;

⑧, vibration: 0 to 100Hz; acceleration: 98M / S2,10g; impact: 4.1JouIes, 3 ft.-1b;

⑨, the working environment: temperature: -20 ℃ ~ + 60 ℃; Relative Humidity: 0 ~ 95% RH; work around the clock; splitter shell is made of 1.5mm thick stainless steel; Protection class: IP65;

⑩, life: more than 8 years.

⑷, traffic light indicator

Indicator lights mounted on the front end of the island of charge for directing vehicle weighing into the region, with high brightness for outdoor use LED, high density arrays are arranged, superior ability to penetrate the fog, light body structure sealed, rain and dust , IP65 protection standards, low power consumption, long life, good weather resistance.

⑸, control cabinet

①, installation costs island place, using basic installation, control cabinet power supply unit, weighing instruments, axis identification instruments and external control units, weighing field device data are transmitted to the control cabinet, after treatment by RS232 Interface lane toll uploaded to the computer.

②, control cabinet with 1.5mm stainless steel design, the use of anti-theft door locks, door to take edging seal protection; entire cabinet have rain, dust; cabinet temperature control device enables the internal maintained at an appropriate the temperature range; with lightning, anti-surge means for controlling the internal structure of the cabinet arrangement is reasonable, easy to maintain.

③, when a device fails, it can send a clear message through hardware and software fault;

④, the working environment: temperature: -20 ℃ ~ + 60 ℃; Relative humidity: 0 ~ 95% RH;

⑤, protection class: IP65.

⑥, stainless steel 650 (width) × 600 (depth) × 800mm (high)

⑦, Power: AC220V (+ 10% -15%) 50 ± 1Hz

⑧, the working environment: Temperature: -40 ~ + 80 ℃ Relative humidity: ≤95%
