Automatic Call Distribution System

Automatic Call Distribution is used where a large number of incoming calls are processed. The system enables the processing of an increased number of daily incoming calls, and facilitates supervisor’s management of the operators. The monitoring of on and off duty, the work efficiency, wage administration, etc., are all processed automatically by computers.

The system reasonably arranges the operator resources according to a specific algorithm, and analyzes the customer’s call number, call time, selected service and other factors, and automatically assigns the customer’s call to the most suitable operator.



  • IVR intelligent navigation: Provide customers with self-service voice services and guide customers to choose manual service content or self-service.
  • ACD intelligent distribution: ACD (Automatic Distributed Traffic) intelligently queues up customer calls and distributes traffic according to a pre-set strategy.
  • Service time strategy: Set up corresponding service procedures according to different time periods such as commuting and holidays.
  • Member identification: When a customer calls, the member information is inquired according to the caller number, and different service processes are entered according to the membership status.
  • Seat queue: The operator is added to the agent queue, and the system automatically allocates the traffic, and monitors the traffic situation of the agent queue in real time.
  • Satisfaction survey: After the call, guide the customer to evaluate the service, and evaluate the overall service quality through statistical reports.

Anti-Lock Braking System (ABS)

ABS is used to prevent a vehicle’s wheel from locking as a result of excessive operation of the service brake, especially on a slippery road surface. During such situations, the vehicle may become unstable and/or less controllable.


Overall diagram of an ABS  in a car:

An ABS consists of three main parts: actuators, sensors and a controller system. Actuators transmit the driver’s pressure on the brake pedal to the braking system. Sensors essentially collect information that the controller needs in order to detect potentially dangerous situations in which the ABS can help stabilize the vehicle and avoid skidding. The controller system decides on both when and how to use the features of the ABS as a whole in order to best assist the driver.The ABS control unit is based on the microcontroller unit system board STM32F446MC. The ABS control unit is used to receive the braking signal from the electric brake pedal, the ABS operation signal from the switch unit, the wheel speed signal from the wheel speed sensor and the fault signal from the brake control unit, to execute the ABS algorithm, and to output the signal to the brake control unit. The schematic of the ABS control unit is illustrated in

Automobile Anti-Collision Radar System

The automobile anti-collision radar system based on frequency-modulated continuous wave (FMCW), can measure the distance and velocity of a target and effectively avoid car crashes by alarming or braking, making the driving safety from “passive” to “active”.

The system comprises three parts:

  • Signal collection: use radar sensor and filter measure the speed of the vehicle, the speed of the vehicle ahead, and the distance between the two vehicles.
  • Data processing: the spectral analysis is performed by means of FFT and the frequency measurement results are converted into distance information and velocity information; and different warning modes are adopted according to the measurement results.
  • Actuator: Responsible for implementing instructions from the data processing system, issuing alarms and reminding the driver to brake. If the driver does not execute the instructions, the actuator will take measures, such as closing the windows, adjusting the seat position, locking the steering wheel, and automatically braking.


Radar Features:

  • Modulation: FMCW
  • Transmit frequency: 77GHz
  • Accurately measure the direction, range, velocity and angle of stationary and moving targets
  • Detection Range: 0.2~170m (short, middle mode, ±45˚), MAX detection range 170 meters, assist drivers to make judgement in advance to ensure the safety of vehicles and personnel.
  • Accuracy:  ±0.1m



  • Traffic Monitoring
  • Speed/Direction Reporting
  • Presence Detection
  • Collision Avoidance
  • Lane Change assistant
  • Rear crash collision warning
