In order to achieve the purpose, the scheme provides an intelligent home system which comprises a cloud server, an intelligent mobile phone terminal, an alarm module and a data acquisition module; the cloud server is respectively in wireless connection with the smart phone terminal, the alarm module and the data acquisition module; the data acquisition module comprises at least one ZigBee terminal;

The intelligent mobile phone terminal sends a household appliance control instruction, and the household appliance control instruction reaches the ZigBee terminal node through the cloud server to realize remote control on household appliances;
the ZigBee terminal is wirelessly connected with a carbon monoxide detection box; the carbon monoxide detection box comprises a box body and a palladium chloride solution; the upper end of the box body is provided with a sieve mesh, the bottom of the box body is connected with a first pipeline, and a floating ball is arranged in the first pipeline; the first pipeline is provided with a pressure sensor which is in communication connection with a corresponding ZigBee terminal; the upper end of the first pipeline is arranged outside the box body, the lower end of the first pipeline is arranged in the box body, and the lower end of the first pipeline is connected with a second pipeline made of calcium carbonate; the upper end of the second pipeline is sealed; the palladium chloride solution is arranged in the box body, and the height of the sealing position at the upper end of the second pipeline is lower than that of the palladium chloride solution.
The principle of the scheme is as follows: firstly, the carbon monoxide detection box and the ZigBee terminal corresponding to the carbon monoxide detection box are placed in a kitchen or the like where carbon monoxide is easy to generate, and then the carbon monoxide detection box is placed beside a carbon monoxide generation source. When no carbon monoxide is generated in the kitchen, the concentration of the carbon monoxide in the air is not more than 0.01 percent, and the carbon monoxide in the air hardly reacts with the palladium chloride solution in the box body. When carbon monoxide is generated in the kitchen, the carbon monoxide in the air continuously reacts with the palladium chloride solution in the box body to generate metal palladium (Pd) powder, carbon dioxide and hydrochloric acid along with the gradual increase of the concentration of the carbon monoxide.
Because the uppermost part of the palladium chloride solution in the box body can firstly react with carbon monoxide in the air to generate hydrochloric acid, and then the generated hydrochloric acid directly reacts with the upper end part of the second pipeline, because the upper end part of the second pipeline is a plane, the plane shape can contact more hydrochloric acid and then react with the hydrochloric acid to dissolve the second pipeline formed by calcium carbonate. Then liquid in the box body passes through the second pipeline and then enters the first pipeline, so that a floating ball in the first pipeline rises, the rising floating ball touches the pressure sensor, the pressure sensor sends a signal to the corresponding ZigBee terminal, the corresponding ZigBee terminal sends the signal to the cloud server and stores the signal, and the alarm module alarms according to an alarm signal sent by the cloud server to remind an indoor user of paying attention to the fact that the indoor carbon monoxide concentration is higher and processes the indoor carbon monoxide as soon as possible.
Then the smart phone terminal interface acquires information and then issues an alarm signal to remind a user of paying attention, the user can operate the smart phone terminal interface after checking the information or the smart phone terminal automatically closes sources releasing carbon monoxide such as a natural gas pipeline and a cooking bench in a house through program setting, and meanwhile, an indoor window is opened to ventilate and disperse the indoor carbon monoxide.
The palladium chloride solution reacts to generate metal palladium (Pd) powder which falls to the bottom of the box body because of self gravity and cannot be attached to the wall of the second pipeline to prevent the second pipeline from reacting with the hydrochloric acid.

When the floating ball contacts the pressure sensor, the pressure sensor transmits a signal to the PLC, the PLC starts the fan to suck carbon monoxide in the air into the palladium chloride solution through the channel, so that the palladium chloride solution absorbs the carbon monoxide to eliminate the carbon monoxide in the air.
Furthermore, the pipeline is made of rubber, the rubber does not react with hydrochloric acid, and the corrosion of the rubber by hydrochloric acid generated by the reaction of a palladium chloride solution and carbon monoxide is avoided.
