FIG. 5 is a flow chart of the steps of a simulated annealing algorithm.
As shown in fig. 5, the set control command algorithm is a simulated annealing algorithm, and the basic idea is as follows:
(1) initializing, namely, initializing the temperature T (which is sufficiently large), randomly generating an initial solution W, and obtaining the iteration times L of each value T;
(2) carrying out the steps (3) to (6) on k which is 1, … … and L;
(3) generating a new solution w';
(4) calculating an increment Δ f (w') -f (w), where f (w) is an objective function;
(5) if Δ f <0, accepting w 'as a new current solution, otherwise accepting w' as a new current solution with probability exP (— Δ f/T);
(6) and if the termination condition is met, outputting the current solution as the optimal solution, and ending the program.
The termination condition is typically taken to terminate the algorithm when no consecutive number of new solutions have been accepted.
FIG. 6 is a schematic diagram of a hill-climbing algorithm and a simulated annealing algorithm to obtain a solution.
As shown in fig. 6, assuming that a is the current solution, the hill-climbing algorithm continues searching forward, and when B, which is the local optimal solution, is searched, the search is stopped.
The simulated annealing algorithm receives a solution worse than the current solution with a certain probability, so that the local optimal solution may be jumped out to reach the global optimal solution. In view of the above, after the local optimal solution B is searched, the simulated annealing algorithm will accept a rightward shift with a certain probability. The peak D between BC may be reached after several such moves that are not locally optimal, thus jumping out the locally optimal solution B and continuing to move to the right makes it possible to obtain the globally optimal solution C. The present embodiment employs a simulated annealing algorithm.
In this embodiment, the set control command algorithm includes the following steps:
step one, making K equal to 1,
step two, generating an intermediate control command S' by disturbance,
step three, substituting the temperature T detected by the temperature detection unit 20, the initial control command S, and the intermediate control command S 'into the following equation (1) and calculating an increment Δ T', if Δ T '< 0, making S ═ S', otherwise making S ═ S 'with a probability exP (— Δ T'/T),
△t’＝C(S’)-C(S) (1)
step four, K is equal to K +1, when K is equal to L, the step five is entered, otherwise, the step two is entered,
step five, judging whether the termination condition is met, outputting S as a control instruction when the termination condition is not met, otherwise, entering the step one,
wherein C (S) is an evaluation function value for S, C (S ') is an evaluation function value for S ', K is an iteration number, L is a set maximum iteration number value, and the termination condition is that S is not set to S ' for a plurality of consecutive times in step three.
In this embodiment, the artificial intelligence processing center 40 is capable of continuously learning and adjusting itself. After generating the control command, the artificial intelligence processing center 40 sends the control command as a history control command, a temperature signal at the time of sending the history control command as an initial temperature signal, and a temperature signal after a predetermined time has elapsed since sending the history control command as a command-implemented temperature signal to the dedicated database 50. In the present embodiment, the predetermined time is 15 s.

As shown in fig. 5, in the first embodiment, the operation flow S1 of the temperature control operation of the intelligent temperature control system 100 includes the following steps:
in step S1-1, the plurality of face recognition devices 10 perform face recognition on the people in the plurality of regions to obtain a plurality of crowd characteristics, and respectively send the crowd characteristics corresponding to each region to the artificial intelligence processing center 40, and then the process proceeds to step S1-2.
In step S1-2, the temperature detectors 20 detect temperatures in the areas in real time to generate temperature signals, and transmit the temperature signals to the smart processing center 40, and the process proceeds to step S1-3.
In step S1-3, the artificial intelligence processing center 40 receives the crowd characteristics and the corresponding temperature signals of each region, obtains the historical control commands corresponding to the similar crowd characteristics and the temperature signals in the dedicated database 50 based on the crowd characteristics and the corresponding temperature signals, and uses the historical control commands as the current initial control commands, and then proceeds to step S1-4.
And S1-4, the artificial intelligence processing center 40 obtains the temperature which the region should reach based on the crowd characteristics as a target temperature, further generates a control instruction through a set control instruction algorithm according to the target temperature, the temperature signal corresponding to the region and the initial control instruction, respectively sends the air volume control instruction and the opening degree control instruction to the air conditioner air outlet control mechanism 30 and the electric window opening control mechanism in the corresponding region, and then enters S1-5.
In step S1-5, the artificial intelligence processing center 40 sends the control command as a history control command, the temperature signal at the time of sending the history control command as an initial temperature signal, and the temperature signal after sending the history control command for a predetermined time as a command to the dedicated database 50, and then proceeds to step S1-6.
At step S1-6, the dedicated database 50 receives and stores the historical control command, the initial temperature signal, and the post-command temperature signal, and then enters the end state.
In the above operation flow, the initial control command in step three may also be randomly generated by the artificial intelligence processing center 40.
