Control system for controlling intelligent system to reduce power consumption based on bluetooth device

A control system for controlling an intelligent system to reduce power consumption based on a Bluetooth device, comprising:

• a main control chip of the intelligent system;
• the Bluetooth device connected with the main control chip;
• a controller connected with the Bluetooth device and the main control chip, respectively, wherein the controller is connected with a power supply and is used for controlling an on and off of a power supply circuit of the main control chip;
• an isolation circuit connected among the Bluetooth device, main control chip and the controller, when the controller controls the power supply circuit of the main control chip to be switched off, the isolation circuit enables the Bluetooth device at an enabled state,
• wherein the isolation circuit includes a first isolation circuit and a second isolation circuit,
• the first isolation circuit is a first triode, the first triode comprising a first base, a first collector and a first emitter;
• wherein the first base is connected with a WI_PWREN pin of the main control chip, and is provided with a first base resistor;
• the first collector is connected with the first controller, the first collector is also connected with a WIFI_PWRENI pin of the Bluetooth device, and a first collector resistor is disposed between the first collector and the controller;
• and
• the first emitter is grounded;
• the second isolation circuit is a second triode, the second triode comprising, a second base, a second collector and a second emitter;
• wherein the second base is connected with BT_EN pin of the main control chip, and is provided with a second base resistor;
• the second collector is connected with the second controller, the second collector is also connected with a BT_ENI pin of the Bluetooth device, and a second collector resistor is disposed between the second collector and the controller;
• and
• the second emitter is grounded.
