[0001] The utility model relates to computer technical field especially a tobacco risk early warning device based on multimodal cloud technique. BACKGROUND

[0002] In recent years, multimodal cloud technology has gradually been applied in various scenarios since its rise, thereby realizing early warning effects in various scenarios and ensuring safety in scenarios. In the tobacco field, the Chinese utility model patent with application number 202322080298.9 provides a double early warning system based on tobacco safety management, which uses a temperature sensor, a smoke concentration sensor, and a carbon monoxide sensor. The system not only warns about the temperature and smoke concentration in the factory building but also warns about the carbon monoxide concentration in the factory building and takes remedial measures, producing a relatively obvious early warning effect.

[0003] However, the double early warning system only performs multimodal detection on the factory building, while the machines producing tobacco are not monitored. If the tobacco production equipment such as the cut tobacco machine in the factory building has multiple local heating phenomena due to loose, corroded, or poor contact electrical connections during long-term production, which may cause a fire, the double early warning system will alarm too late, and the tobacco production equipment such as the cut tobacco machine cannot continue to be used, resulting in significant losses.

[0004] That is, the double early warning system in the prior art has the problem of not being comprehensive when using multimodal cloud technology to warn the factory building, leading to significant losses of the tobacco production equipment in the factory building.

[0005] Therefore, the utility model provides a new scheme to solve this problem. SUMMARY

[0008] The temperature detection unit is connected with the MCU through the temperature confirmation unit.

[0009] Further, the temperature detection unit performs subtraction operation on the first temperature signal and a first temperature signal at a previous moment to obtain a first temperature difference signal, starts the temperature confirmation unit based on the first temperature difference signal, and outputs the first temperature signal to the temperature confirmation unit.

[0010] Further, the temperature confirmation unit performs operation on the second temperature signal and the first temperature signal to obtain the first reminder signal and the second reminder signal.

[0011] Further, the temperature confirmation unit performs subtraction operation on the second temperature signal and the third temperature signal to obtain a second temperature difference signal, and performs operation on the second temperature signal and the first temperature signal based on the second temperature difference signal to obtain the first reminder signal and the second reminder signal.

Figs. 1-2 In the detailed description of the embodiments, the structure content mentioned in the following embodiments will be clearly presented with reference to the drawings.

[0019] The various exemplary embodiments of the utility model will be described below with reference to the accompanying drawings.

[0020] A tobacco risk early warning device based on multi-modal cloud technology, comprising an MCU, the device further comprises an equipment detection module, the equipment detection module comprises a temperature detection unit and a temperature confirmation unit, the temperature detection unit and the temperature confirmation unit detect a first temperature detection point, a second temperature detection point and a third temperature detection point of the tobacco production equipment respectively to obtain a first temperature signal, a second temperature signal and a third temperature signal, and obtain a first warning signal and a second warning signal based on the first temperature signal, the second temperature signal and the third temperature signal, and output the first warning signal and the second warning signal to the MCU;

[0021] The temperature detection unit is connected with the MCU through the temperature confirmation unit.

[0022] The humidity detection unit detects a first temperature signal of the tobacco production equipment based on the temperature sensor U1. The first temperature signal can be the temperature signal of the tobacco production equipment, such as a cut tobacco machine and a tobacco cutting machine. The first temperature signal is divided into two paths. One path is directly output to the inverting terminal of the operational amplifier U1A. The other path is output to the non-inverting terminal of the operational amplifier U1A after being delayed by the resistor R8 and the capacitor C2. The non-inverting terminal of the operational amplifier U1A receives the first temperature signal at the previous time. The inverting terminal of the operational amplifier U1A receives the first temperature signal at the current time. The operational amplifier U1A performs subtraction operation on the two first temperature signals to obtain a first temperature difference signal, which is the temperature change value of the tobacco production equipment at this position between the two times. The first temperature difference signal is judged by the transistor Q2. If the transistor Q2 is not turned on, the temperature change at this position is not significant, and no processing is required. If the transistor Q2 is turned on, the temperature change at this position is significant, and the relay K2 is turned on by the diode D2 and the transistor Q2. The switch S1 is closed by the relay K2, and the temperature confirmation unit is turned on. The capacitor C1 ensures that the relay K1 is continuously powered. The first temperature signal is output to the temperature confirmation unit.

[0023] The temperature detection unit includes a resistor R7, one end of the resistor R7 is connected to the out pin of the temperature sensor U1, the other end of the resistor R7 is connected to one end of the resistor R8, the inverting terminal of the operational amplifier U1A, and one end of the resistor R2, the non-inverting terminal of the operational amplifier U1A is connected to the other end of the resistor R8, one end of the capacitor C2, and one end of the resistor R3, the output terminal of the operational amplifier U1A is connected to the other end of the resistor R2 and the base of the transistor Q2, the collector of the transistor Q2 is connected to one end of the resistor R5 and the positive electrode of the diode D2, the emitter of the transistor Q2 is connected to one end of the resistor R15, the other end of the resistor R5 is connected to the vcc pin of the temperature sensor U1 and the positive electrode of the power supply VCC, the negative electrode of the diode D2 is connected to one end of the capacitor C1 and one end of the relay K2, the other end of the relay K2 is connected to the other end of the capacitor C1, the other end of the capacitor C2, the other end of the resistor R3, the other end of the resistor R15, and the gnd pin of the temperature sensor U1, and is connected to the ground.

[0024] The temperature confirming unit then outputs second temperature signals and third temperature signals of other two temperature-rising parts on the tobacco production equipment, which are output by two other temperature sensors U1 arranged on the tobacco production equipment, respectively. The two parts can also be the same, such as the left and right parts of the motor or the front and rear ends of the cylinder of the cylinder-type cut tobacco dryer. The parts are used for drying cut tobacco, and thus the temperature of the parts rises fastest and reaches the highest temperature value most easily. The second temperature signal and the third temperature signal are transmitted to the operational amplifier U4A through the 1 pin and the 2 pin, the 3 pin and the 4 pin of the switch S1, respectively. The operational amplifier U4A then performs subtraction operation on the second temperature signal and the third temperature signal to output a second temperature difference signal, and performs voltage judgment on the second temperature difference signal based on the triode Q3. If the triode Q3 is turned on, it indicates that the temperature difference between the second temperature signal and the third temperature signal is not large. At this time, the triode Q3 turns on the thyristor Q1 through the diode D3. The thyristor Q1 then transmits the second temperature signal to the operational amplifier U3A. The operational amplifier U3A also receives the first temperature signal output by the temperature detecting unit. The operational amplifier U3A then performs subtraction operation on the second temperature signal and the first temperature signal to obtain a third temperature difference signal. The third temperature difference signal is subjected to voltage judgment by the triode Q4. If the third temperature difference signal turns on the triode Q4, it indicates that the voltage of the first temperature signal is close to that of the second temperature signal at this time, i.e., the temperature of the first temperature signal is close to that of the second temperature signal. The triode Q4 outputs a first reminding signal to the MCU through the diode D4, reminding that the temperature of the tobacco production equipment such as the cut tobacco dryer is rising, but is within a normal range and does not need to be processed. If the third temperature difference signal turns on the diode D3, it indicates that the voltage of the first temperature signal is greatly different from that of the second temperature signal at this time, i.e., the temperature of the first temperature signal is greatly different from that of the second temperature signal. The triode Q4 outputs a second reminding signal to the MCU through the diode D4, reminding that the temperature of the tobacco production equipment such as the cut tobacco dryer is rising, but is greatly different, and cannot produce uniform drying effect on cut tobacco, and needs to be processed or repaired.

[0025] The temperature confirmation unit includes switch S1, the 1 pin of switch S1 is connected with the third temperature signal, the 3 pin of switch S1 is connected with the second temperature signal, the 2 pin of switch S1 is connected with one end of resistor R1, the 4 pin of switch S1 is connected with one end of resistor R9, one end of resistor R1, one end of resistor R16 and anode of thyristor Q1 are connected with the other end of resistor R1, the output end of operational amplifier U1A is connected with one end of resistor R14 and base of triode Q3, the emitter of triode Q3 is connected with the other end of resistor R14, one end of resistor R13, the emitter of triode Q4 and the other end of resistor R5 in the temperature detection unit and connected with positive power supply VCC, the collector of triode Q3 is connected with one end of resistor R10 and positive of diode D1, the negative of diode D1 is connected with the control pole of thyristor Q1 and one end of capacitor C3, the cathode of thyristor Q1 is connected with the non-inverting terminal of operational amplifier U3A and one end of resistor R6, the inverting terminal of operational amplifier U3A is connected with one end of resistor R4, the other end of resistor R7 in the temperature detection unit and the inverting terminal of operational amplifier U1A, the output end of operational amplifier U3A is connected with the other end of resistor R13, the other end of resistor R4, positive of diode D3 and base of triode Q4, the collector of triode Q4 is connected with one end of resistor R12 and positive of diode D4, the negative of diode D4 is connected with the negative of diode D3 and MCU, the other end of resistor R12 is connected with the other end of resistor R6, the other end of capacitor C3, the other end of resistor R10, the other end of resistor R11 and the other end of capacitor C1 in the temperature detection unit and connected with ground.

[0026] As in actual use, the humidity detection unit collects the first temperature signal as 2.7V through temperature sensor U1, and the temperature signal at the last moment is 2V, then the first temperature difference signal obtained through operational amplifier U1A is 0.7V, then the temperature confirmation unit is turned on, then the second temperature signal of 2.9V and the third temperature signal of 2.8V are subjected to subtraction operation through operational amplifier U4A to obtain the second temperature difference signal of 0.1V, then the thyristor Q1 outputs the second temperature signal to the operational amplifier U3A at this time, the operational amplifier U3A outputs the third temperature difference signal of 0.1V between the second temperature signal and the first temperature signal, then the triode Q4 outputs the first reminding signal to the MCU through the third temperature difference signal, reminding that the tobacco production equipment at this time although the temperature rises, but is in the normal range, and does not need to be handled.
