Abstract

The subject of the application is a method for verifying and controlling a heating device installed, in particular, in the sanitary compartments of ambulances, comprising determining a confidence interval for the temperature of the sanitary compartment and taking into account the heating intensity estimated using a differential method, applicable in electronic systems for controlling ambulance heating. The method for verifying and controlling a heating device installed, in particular, in the sanitary compartments of ambulances, comprising determining a confidence interval for the temperature of the sanitary compartment and taking into account the heating intensity estimated using a differential method, in which the temperature is measured using at least one temperature sensor mounted at the point of intersection of the heater outlet axes or in the center of the stretcher, is characterized in thatthat based on the sequence of temperature readings {Ttj}0≤j≤n at moments t0≤t1≤…tn (the moment of the last measurement is less than the required heating time tn <treq przedziału sanitarnego) wyznacza się wartość oczekiwaną parametru efektywności ogrzewania przedstawioną za pomocą wzoru A, wariancję przedstawioną za pomocą wzoru B, gdzie: Tmax — maksymalna temperatura ogrzania; T0 — poziom referencyjny, równy temperaturze początkowej pomiaru; Ttj — wartość temperatury w momencie tj, 0≤j≤n; Treq — minimalny wymagany poziom temperatury po czasie treq; treq — wymagany czas ogrzewania ambulansu, dla którego temperatura przedziału sanitarnego powinna być nie mniejsza niż Treq, następnie dla poziomu istotności α wyznaczamy przedział ufności (T15(λL),T15(λU)), gdzie granice przedziału wyznaczamy za pomocą wzoru C, natomiast λL to wzór D, λU to wzór E oraz wielkość u1-α / 2 jest kwantylem rzędu 1—α / 2 dla rozkładu normalnego N(0,1); jeżeli na podstawie obserwacji {(Ttj,tj)}0≤j≤n,if the inequality T15(λU)≤Treq is met, then with probability 1—α / 2 the required temperature of the sanitary compartment will not be achieved and the power of the heating device should be increased so that at the moment treq the temperature of the sanitary compartment exceeds the required value Treq; if, on the basis of the observation {Ttj)0≤j≤n, the inequality T15(λL)≥Treq is met, then with probability 1—α / 2 it should be assumed that the minimum required value of the temperature Treq of the sanitary compartment after time treq will be achieved; if, on the basis of the observation {(Ttj,tj)}0≤j≤n, the required temperature belongs to the confidence interval, i.e. Treqϵ(T15(λL),T15(λU)), then the behavior of the temperature of the sanitary compartment should be observed.,
