When the analog processing system is in a simulation state, real data does not need to be considered in data processing, and the whole simulation processing process is based on simulation data input by a user. For example, when the current room temperature is 20 degrees and the room temperature to be simulated is 18 degrees, the running condition of the system is controlled, and a simulation temperature, such as 18 degrees, is directly set on a page of the analog processing system by using a simulation function, so that the analog processing system processes according to the set simulation temperature.
In step S230, the received target simulation input data may be calculated by:

The specific description can refer to the description of step S130, and the same technical effects can be achieved, which will not be repeated.
S240, determining the target simulation output data to output to the simulation output data based on the simulation output data corresponding to the preset simulation output data.
According to the analog quantity processing method, various processing states can be integrated on one system, for example, the analog quantity processing system can simultaneously comprise a simulation state and a non-simulation state, and at the moment, only a part of the analog quantity processing system is required to be ensured to be in the simulation state, so that corresponding simulation actions are executed; and the other part of the processing system is in a non-simulation state, and can execute alarm operation in the non-simulation state, namely the simulation operation and the alarm operation can be performed simultaneously. Therefore, a plurality of functional modules can be formed in the system, and the functional modules are not affected when executing actions, so that the standardization of the system is improved, the processing time of the system is saved, and the cost is reduced.

and S340, if the target simulation control data is detected not to be the preset simulation control value, determining the target actual analog quantity input data to be an algorithm input value.
In the step, target simulation control data is input through a simulation data control port which is selected by a user and corresponds to the simulation control data, then the target simulation control data is compared with a preset simulation control value, the state of the system is determined according to the comparison result, and a value is input by a further determination algorithm according to the determined state; when the target simulation control data is the preset simulation control value, the system is in a simulation state, and at the moment, the algorithm input value is the target simulation input data; when the target simulation control data is not the preset simulation control value, the system is in an un-simulation state, namely an actual working state, and at the moment, the algorithm input value is the target actual analog input data.
In practical application, the analog processing system uses either an actual program or a simulation program to perform operation, so the analog processing system either receives target actual analog input data, where the target actual analog input data may include multiple or all of an analog input signal InDp, an upper limit alarm value inopdp, a lower limit alarm value InLowDp, an upper limit alarm delay time TdUp, and a lower limit alarm delay time TdLow; or receive target simulation input data.

In addition, the open/close state of the analog-to-analog state switch Off can be used to determine whether the system is in an analog state or an un-analog state, i.e., when Off is on, the system is in an analog state, and when Off, the system is in an un-analog state.
Specifically, judging whether the simulation control input Off is true, if so, taking target simulation input data as an algorithm input value AlgDp; if not, the target actual analog input data is used as an algorithm input value AlgDp.
