[0066] Before the safety control method is controlled, the type of the system and the parameters of the safety control are set: the type of the system Es and the control parameters of the safety working are set, including the highest normal working temperature T max , the low-temperature early warning value T min , the smoke data acquisition error limit value S y_dif , the total sampling configuration point number n of the temperature sensor, the total sampling configuration point number m of the smoke sensor, the temperature correction coefficient γ, the control output temperature control adjustment parameter u and the fire control parameter.

[0067] Step S201: collecting the temperature data and smoke data of multiple measurement points in the system in real time by using multiple temperature sensors and multiple smoke sensors;

[0068] Step S202: collate the temperature data and the smoke data to obtain the temperature data set and the smoke data set;

[0069] Step S203: calculate the highest temperature and the lowest temperature of the temperature data set by using a formula;

[0070] Real-time acquisition of multi-point temperature data t1, t2,... t n , and calculation of real-time highest temperature value t max according to formula 1 min ;

[0071] t max = max{t1, t2,... t n} (1)

[0074] Step S204: judge whether the highest temperature is greater than a preset highest temperature and whether the lowest temperature is less than a preset lowest temperature;

[0075] Step S205: output a control instruction according to the judgment result of step S203;

[0076] The temperature control control output signal is a PWM control signal with adjustable duty cycle, and the formula is:

[0077]

[0078] Wherein, T d_PWMcon(t) is the adjustment value of the temperature control PWM signal, wherein u is a control output temperature control adjustment parameter, and ε is the power of the machine working.

[0079] The collected temperature data is accurately distinguished, specifically: if the real-time highest temperature value exceeds the set highest value, the high-temperature control signal is started, and the temperature control PWM signal is adjusted according to u·ε(t max -T max) setting the adjustment value of the PWM wave control signal, adjusting the duty cycle of the PWM control signal according to the adjustment value of the PWM wave control signal, the greater the difference between the maximum temperature and the preset temperature value, the greater the duty cycle of the output PWM wave control signal, the faster the cooling power of the cooling system, and as the maximum temperature decreases, the duty cycle of the PWM wave control signal output each time also decreases, so the cooling power of the cooling system also decreases, the power of the cooling system is adjusted in real time according to the change of the temperature, which can accurately adjust the power of the cooling system and save energy; when the real-time minimum temperature is lower than the set low temperature warning value, the low temperature control signal is started, and the temperature of the energy storage system is raised according to u·ε(T min -t min ) setting the adjustment value of the PWM wave control signal, adjusting the duty cycle of the PWM control signal according to the adjustment value of the PWM wave control signal, the greater the difference between the maximum temperature and the preset temperature value, the greater the duty cycle of the output PWM wave control signal, the faster the cooling power of the cooling system, and as the maximum temperature decreases, the duty cycle of the PWM wave control signal output each time also decreases, so the cooling power of the cooling system also decreases, the power of the cooling system is adjusted in real time according to the change of the temperature, which can accurately adjust the power of the cooling system and save energy; when the real-time minimum temperature is lower than the set low temperature warning value, the low temperature control signal is started, and the temperature of the energy storage system is raised according to u·ε(T min -t min ) value, the greater the duty cycle of the PWM wave control signal, the faster the corresponding heating power of the heating system; when the temperature of the energy storage system is normal, the PWM control signal is set to 0, and the heating and cooling systems are turned off. The present application not only obtains the starting and stopping control signals, but also accurately controls the power of the cooling system and the heating system according to the real-time system temperature, reduces the control energy consumption, and improves the control precision.

[0081] Step S206: judging whether the smoke data set is an abnormal situation by using a formula;

[0082] Read the multi-point smoke collection parameters s1, s2,..., s m , calculate the smoke abnormal situation, and the calculation formula is:

[0083]

[0084] Among them, s1, s2,..., s m are the real-time data of m smoke detection sensors set according to the system type, S y_flag is a fire control judgment signal flag.

[0085] Step S207: if the smoke data is an abnormal situation, outputting a fire extinguishing equipment opening instruction and a smoke warning instruction;

[0086] Step S208: when the smoke data collected afterwards is normal data, outputting a fire extinguishing equipment closing instruction and a smoke warning closing instruction.

[0087] The collected smoke sensing parameters are identified and determined, specifically: As shown in the formula, if the abnormal value of the smoke data exceeds the set error limit value, that is, S y_flag = 1, the fire control signal is started, including the starting control of the switch type fire extinguishing equipment and the pulse type smoke warning instruction output, wherein the pulse type smoke indication is adjusted and controlled according to the abnormal value in real time to output the fire control parameter; if the abnormal value of the smoke data is lower than the set error limit value, that is, S y_flag = 0, the fire control signal output is closed.

[0088] The collected temperature, smoke information and data of each path are stored, and the feedback safety control action value log information is recorded.

[0089] In the embodiment, the safety control method of the system is described in detail, the real-time temperature data and the data collected by the smoke sensor are taken as the standard of the starting control signal, whether the highest temperature and the lowest temperature of the system meet the requirements is determined respectively, different control instructions are made according to the calculation results, precise control is realized, and different control strategies are realized according to the height of the temperature, and the control is stopped when the temperature becomes normal; then the smoke data is also judged, whether it belongs to an abnormal situation, if it belongs to an abnormal situation, a fire extinguishing equipment opening instruction and a smoke warning instruction are issued, the fire extinguishing device is controlled to extinguish the fire, and the smoke warning device is controlled to alarm, until the collected smoke data is normal data, a closing instruction is output. According to the real-time collected temperature and smoke data as the starting signal, compared with the control strategy of the prior art, the control of the present application is more accurate, the comprehensive energy consumption of the conventional control is reduced, and the control effect is improved.

The adjusted PWM wave control signal is input into the heating system, and the heating system is started to heat up according to the adjusted PWM wave control signal. like If so, the PWM wave control signal is set to 0, and the heating system is turned off.

8.
