And S4, if the smoke exhaust fan does not work, controlling the monitoring host to enter a sleep mode.

When the monitoring host is in the sleep mode, the processor can cut off the power supply of each device in the monitoring host, and the processor also enters the sleep mode and is in a low power consumption state. The power consumption of the monitoring host in the sleep mode is lower than that of the monitoring host in the oil smoke concentration monitoring of the oil smoke gas, so that the power supply pressure of the wind driven generator and the power supply module can be reduced, and 24-hour continuous power supply is facilitated.

And S5, if the smoke exhaust fan works, acquiring the oil smoke concentration of the oil smoke gas through an oil smoke sensor, and sending the oil smoke concentration to a monitoring platform through a communication module.

Wherein, if smoke exhaust fan is working, show that the exhaust pipe is discharging oil smoke gas to the outside this moment, at this moment, the treater starts the air pump and begins to extract oil smoke gas, and open sensor power and communication module's power, acquire the gaseous oil smoke concentration of oil smoke through the sensor in the monitoring host computer and wait to detect data, and connect monitoring platform through communication module, with the gaseous detection data such as oil smoke concentration and send to monitoring platform, thereby make monitoring platform's staff judge whether up to standard of the oil smoke gas of exhaust pipe emission, realize the on-line monitoring of oil smoke concentration.

And S6, controlling the monitoring host to enter a sleep mode.

After the detection data such as oil smoke concentration and the like are reported to the monitoring platform, the monitoring host is controlled to enter a sleep mode, at the moment, the power supply of the sensor power supply and the power supply of the communication module are turned off, and the processor enters the sleep mode, so that the power supply pressure of the wind driven generator and the power supply module is reduced, and 24-hour continuous power supply is facilitated.

And S7, when the first timing duration reaches a first preset threshold value, controlling the monitoring host to exit the sleep mode, and repeating the steps S2 to S6.

And when the first timing duration reaches a first preset threshold, the timer is triggered in an interruption mode, the processor is awakened, the processor is quitted from the sleep mode, and the steps S2-S6 are repeated to realize the online monitoring of the oil smoke concentration.

The first preset threshold is set according to the time interval of reporting the detection data required by the monitoring platform. For example, the first preset threshold may be between 30 seconds and 3600 seconds, but is not limited thereto.

It can be understood that the larger the first preset threshold is set, the lower the frequency of reporting detection data such as oil smoke concentration and the like to the monitoring platform by the oil smoke online monitoring device is, the lower the frequency of the monitoring host exiting the sleep mode is, the lower the average power consumption of the oil smoke online monitoring device is, and the longer the duration of the oil smoke online monitoring device is facilitated to be increased.

Optionally, acquire the oil smoke concentration of oil smoke gas through the oil smoke sensor, include:

the method comprises the steps that the real-time oil smoke concentration of once oil smoke gas is obtained through an oil smoke sensor every a first preset time, and the number of the obtained real-time oil smoke concentrations is a first preset number.

And calculating the average value of the real-time oil smoke concentrations of the first preset number as the oil smoke concentration.

For example, the processor may continuously read the values of the sensors for a first predetermined number of times (e.g., 5 times) at intervals of a first predetermined time (e.g., 1 second), average the values of the sensors, and report the averaged values to the monitoring platform, so as to improve accuracy of detection data such as reported oil smoke concentration.

Wherein, it is long when first predetermineeing and first predetermineeing quantity all can set up according to the actual demand, the embodiment of the utility model provides a do not do the injecing to this.

In this embodiment, a low power consumption control strategy is designed, when it is monitored that the smoke exhaust fan works, the online oil smoke monitoring device periodically starts the air pump to begin to pump oil smoke gas according to a requirement of a time interval of detection data reported by the monitoring platform, acquires detection data such as oil smoke concentration of the oil smoke gas through the sensor, and reports the detection data to the monitoring platform. When the smoke exhaust fan does not work and in the time interval of reporting the detection data, the monitoring host is controlled to enter the sleep mode, so that the power consumption of the oil smoke online monitoring device is reduced, the improvement of the endurance time is facilitated, and 24-hour continuous power supply is realized.

It should be understood that various forms of the flows shown above may be used, with steps reordered, added, or deleted. For example, the steps described in the present invention may be executed in parallel, may be executed sequentially, or may be executed in different orders, as long as the desired result of the technical solution of the present invention can be achieved, and the present invention is not limited thereto.

The above detailed description does not limit the scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions may be made in accordance with design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
