Abstract

The invention discloses a collision avoidance controller for a pram, which belongs to the technical field of controllers and comprises a power module, a CPU (central processing unit) module, an ultrasonic transmission driving module, an ultrasonic receiving module, a signal amplification processing module, an alarm and a receiving and transmitting integrated probe module. The power module is electrically connected with the CPU module, the CPU module is respectively electrically connected with the ultrasonic transmission driving module, the signal amplification processing module and the alarm, the ultrasonic transmission driving module is electrically connected with the receiving and transmitting integrated probe module, and the signal amplification processing module is electrically connected with the receiving and transmitting integrated probe module by the ultrasonic receiving module. The collision avoidance controller has the advantages that a ranging sensor is mounted on the pram in a specific direction, and collision avoidance protection for a pram body in the specific direction is realized; when the distance from the pram to an obstacle is equal to or smaller than a preset value, the alarm can raise an alarm to remind a user that a child is in danger; when the distance from the pram to the obstacle is larger than the preset value, the collision avoidance controller does not actuate any operation; and the collision avoidance controller is simple in structure and convenient in use.

Example Embodiment

[0008] The present invention will be further described below in conjunction with the drawings.
[0009] Such as figure 1 As shown, the present invention includes a power supply module, a CPU module, an ultrasonic transmission driving module, an ultrasonic receiving module, and a signal amplification processing module. It also includes an alarm and a transceiver integrated probe module. The power supply module is electrically connected to the CPU module, and the CPU module is respectively connected to the ultrasonic transmitter The driving module, the signal amplification processing module and the alarm are electrically connected, the ultrasonic transmission driving module is electrically connected with the transceiver integrated probe module, and the signal amplification processing module is electrically connected with the transceiver integrated probe module through the ultrasonic receiving module.
[0010] Working process: After startup, the ultrasonic sending and driving module sends out ultrasonic signals, and the sent ultrasonic signals encounter obstacles and return to be received by the transceiver integrated probe module, and convert mechanical sound waves into weak electrical signals, and then transmit them to Ultrasonic receiver module, then the weak electrical signal is amplified and filtered by the signal amplifying processing module, and the analog signal is converted into a digital signal that can be recognized by the CPU, and then transmitted to the CPU module. The CPU module calculates the obstacles according to the time interval of sending and receiving. When the distance to the obstacle reaches or is less than the preset value, the alarm will sound an alarm to remind the user that the child is in danger. When the distance to the obstacle is greater than the preset value, no operation is performed.
