3. the temperature regulator calculates the temperature difference between the temperature set value and the current temperature value;
4. if the temperature difference value is smaller than the preset temperature difference value, the temperature of the micro fluidized bed is not required to be adjusted for the moment, and the temperature set value sent by the user can be accepted again;
5. if the temperature difference is larger than or equal to the preset temperature difference, the temperature of the micro fluidized bed does not meet the user requirement, and therefore the temperature regulator generates a temperature driving signal according to the temperature difference and drives the temperature of the micro fluidized bed to meet the user requirement.
Wherein the user may be an operator using a micro-fluidized bed; the temperature regulator is a technical service tool for temperature regulation, and the temperature regulator can respond to, process and regulate the temperature according to a temperature set value sent by a user. As shown in fig. 1, after the temperature regulator receives the temperature setting value, if the temperature difference value set by the temperature regulator is satisfied, the temperature of the micro fluidized bed is correspondingly regulated; the micro fluidized bed is a reactor which makes solid particles in a suspension motion state by utilizing gas or liquid to pass through a granular solid layer and performs a gas-solid phase reaction process or a liquid-solid phase reaction process, is also called as a fluidized bed, generally has the advantages of simple structure, reliable work, convenient regulation and control, high heat and mass transfer efficiency and the like, and is often used as a biomass pyrolysis reactor to prepare bio-oil.
In detail, in the embodiment of the present application, the temperature regulator includes a temperature receiving module, a temperature collecting module, a temperature difference calculating module, a temperature generating module, and a temperature driving signal generating module. After the thermostat receives the temperature set value, the data interaction process between the modules is as shown in fig. 2, and includes:

2. the temperature acquisition module acquires a current temperature value from the micro fluidized bed, inputs the current temperature value into the temperature difference calculation module, and calculates the current temperature value and the temperature set value to obtain a temperature difference value;
3. if the temperature difference value is smaller than the preset temperature difference value, the temperature of the micro fluidized bed is not required to be adjusted temporarily, so that the temperature receiving module is informed of re-receiving the temperature set value input by the user;
4. if the temperature difference value is larger than or equal to the preset temperature difference value, the temperature of the micro fluidized bed does not meet the requirement of a user, and therefore the temperature generation module is informed to generate the current adjustable temperature;
5. and generating a temperature driving signal according to the current adjustable temperature by using a temperature driving signal generating module, and driving the micro fluidized bed to change the temperature to the current adjustable temperature.
Referring to fig. 3, a schematic flow chart of a method for intelligently adjusting temperature based on a micro fluidized bed according to an embodiment of the present application is shown. In this embodiment, the method for intelligently adjusting the temperature based on the micro fluidized bed includes:
and S1, receiving a temperature set value input by a user, and acquiring the current temperature value and the current time of the micro fluidized bed.
The method can simultaneously dock a plurality of users, so that each user can be docked in a multithreading mode, and the temperature setting of the micro fluidized bed by each user can be responded to the maximum extent.
Further, referring to fig. 4, the obtaining of the current temperature value of the micro fluidized bed includes:

s12, generating a constant current by using the temperature test circuit where the platinum resistor is located and passing through the platinum resistor;
s13, calculating the voltage difference generated by the platinum resistor under the constant current;
and S14, converting the voltage difference into the current temperature value by using a pre-constructed analog-to-digital conversion interface.
In the embodiment of the present application, since the platinum resistor has the advantages of small temperature coefficient of resistance dispersibility, good linearity, good sensitivity and stability, and the like, the method can help the application to perform temperature adjustment more accurately, and further, in the embodiment of the present application, the Pt100 platinum resistor is used, but the Pt100 platinum resistor is easy to fail in a high temperature environment, and therefore, the calculating of the voltage difference generated by the platinum resistor under the constant current includes:
judging whether the platinum resistor generates a voltage difference under the constant current;
when the platinum resistor does not generate a voltage difference under the constant current, the platinum resistor is removed from the inner wall of the micro fluidized bed, and a user is informed to replace the platinum resistor;
judging whether the replaced platinum resistor generates a voltage difference under the constant current;
and when the replaced platinum resistor still does not generate voltage difference under the constant current, starting the pre-built alarm device.
In detail, after the platinum resistor extends into the inner wall of the micro fluidized bed, the temperature of the platinum resistor extending into one side of the inner wall of the micro fluidized bed changes, so when a temperature test circuit where the platinum resistor is located generates a constant current and passes through the platinum resistor, a voltage difference is generated due to uneven heating of two ends of the platinum resistor, the current temperature value is generated by the voltage difference, if the platinum resistor does not generate the voltage difference, the platinum resistor is possibly failed due to a high-temperature environment, and the voltage difference is not generated when the platinum resistor is further replaced, the micro fluidized bed or the temperature regulator is abnormal, so that a technician is required to check, and an alarm device is started.
It can be seen that the current temperature value represents the real-time temperature of the micro fluidized bed at the current moment.
And S2, calculating the temperature difference between the current temperature value and the temperature set value.
And calculating the difference value between the A degree and the B degree to obtain the temperature difference value when the temperature set value input by the user is A degrees and the current temperature value of the micro fluidized bed is B degrees.

In another embodiment of the present application, if the temperature difference is smaller than the preset temperature difference, it indicates that the current temperature value of the micro fluidized bed meets the temperature setting value input by the user, and the micro fluidized bed does not execute the temperature adjustment operation for the moment.
If the temperature difference is greater than or equal to the preset temperature difference, it indicates that temperature adjustment operation needs to be performed on the micro fluidized bed, but since temperature adjustment is limited by the temperature adjuster, temperature adjustment parameters corresponding to the temperature adjuster need to be acquired.
The response speed parameter is the ratio of the predicted time for the temperature regulator to complete temperature regulation at the current moment to the temperature regulation difference value, and the temperature regulation amplitude parameter is the maximum temperature regulation value which can be completed by the temperature regulator within a fixed time period.

and combining the temperature control deviation integral function of the response speed parameter and the temperature control deviation integral function of the temperature adjusting amplitude parameter according to a preset operation rule to obtain the temperature adjusting function.
Specifically, the temperature adjustment function is:

And B: adjusting the response speed parameter to a preset high-response interval to obtain a high-response parameter, and adjusting the temperature adjustment amplitude parameter to a preset low-amplitude interval to obtain a low-amplitude parameter;
in the embodiment of the present application, the response speed parameter indicates how fast the temperature regulator can respond to the temperature setting value input by the user, and since the user wants the temperature regulator to respond and realize temperature regulation in a short time, the response speed parameter needs to be regulated to a preset high-response interval.
In addition, because the temperature regulation amplitude parameter is too high, the temperature regulation of the micro fluidized bed is easily caused to exceed the range of the temperature set value, so that the temperature regulation amplitude parameter is firstly regulated to a preset low-amplitude interval in the early stage, and the phenomenon that the temperature control of the micro fluidized bed generates too large errors due to the fact that the response speed parameter and the temperature regulation amplitude parameter are both too high is prevented.
And C: replacing the first temperature regulation time interval with a differential interval of the temperature regulation function, and modifying the temperature regulation function by using the high response parameter and the low amplitude parameter to obtain a first temperature regulation function;

Step D: adjusting the response speed parameter to a preset low-response interval to obtain a low-response parameter, and adjusting the temperature adjustment amplitude parameter to a preset high-amplitude interval to obtain a high-amplitude parameter;
in the embodiment of the application, after the temperature regulator has completed the response, that is, after the temperature regulator has started the relevant hardware equipment and prepared to regulate the temperature of the micro fluidized bed, the temperature regulation amplitude parameter can be properly increased, and the rapid temperature regulation of the micro fluidized bed is completed.
Step E: replacing the second temperature regulation time interval with a differential interval of the temperature regulation function, and modifying the temperature regulation function by using the low response parameter and the high amplitude parameter to obtain a second temperature regulation function;
in an embodiment of the present application, the first temperature adjustment function is:
wherein m (Δ t) represents Δ t at the current time1+ Δ t, output temperature of said thermostat, kp2Represents the low response parameter, ki2Is representative of the high-amplitude parameter,

step H: and combining the first adjustable temperature and the second adjustable temperature to obtain the current adjustable temperature.
Therefore, in the embodiment of the present application, the current adjustable temperature includes a first adjustable temperature and a second adjustable temperature, wherein the first adjustable temperature is [0, Δ t ]1]Internal finishing pair micro fluidized bedThe second adjustable temperature is [ delta t ]1,Δt]The temperature of the micro fluidized bed is adjusted.
Therefore, in this embodiment of the present application, the first adjustable temperature and the second adjustable temperature are utilized to generate corresponding temperature driving signals respectively, so as to change the temperature of the micro fluidized bed, and in detail, the utilizing the current adjustable temperature to generate the temperature driving signal to drive the micro fluidized bed to change the temperature to the current adjustable temperature includes:
