The invention discloses a snake escape-proof system by frictional force direction judgment. The snake escape-proof system by frictional force direction judgment comprises a current detection circuit and a force detection circuit and a strong light LED, wherein the current detection circuit comprises a thermistor and a current detector; the force detection circuit includes a force sensor; the current detection circuit is used for detecting a difference value of current and sending the difference value to a processor; the force detection circuit is used for detecting the magnitude value of forcein the direction of the force and judging; the strong light LED is used for preventing snakes from escaping. When the system is started, the processor judges the magnitude of the current value of thecurrent detection circuit and compares the difference value, and detects the magnitude value of force in the direction of the force. If the magnitude of the force value is greater than the set threshold value and the corresponding current value has a difference value, the processor analyzes according to the two values to judge whether there is an escape risk of snakes in the snake house and starts the strong light LED.
