Specifically, in the step S3, the step of determining the electrode sheet set pitch includes:
Acquiring the surface humidity of the electrode plate at the side of the electrode plate contacted with the surface of the patient;
comparing the surface humidity of the electrode plate with a preset humidity;
if the surface humidity of the electrode plate is larger than the preset humidity, increasing the set interval of the electrode plate;

Specifically, the reduction amplitude of the height of the bed where the patient is located is determined by the difference value between the preset average electrocardiosignal intensity and the average electrocardiosignal intensity.
Specifically, the calculation formula of the average electrocardiographic signal intensity is:
Wherein I is the average electrocardiosignal intensity, Ia is the electrocardiosignal intensity monitored by the electrode plate at the same position in the a-th monitoring period, n is the number of the monitoring periods, and n is a natural number which is more than or equal to 1.
In practice, the average value of the preset electrocardiosignals is generally in the range of [0.92mV,0.96mV ].

Specifically, the difference between the preset electrocardiosignal average value and the electrocardiosignal average value is within 0.02mV, and the height of the bed where the patient is positioned is reduced by 5cm; when the difference between the preset electrocardiosignal average value and the electrocardiosignal average value exceeds 0.01mV, the height of the patient bed is reduced by 2cm every time the difference is smaller than 0.01mV, for example, the electrocardiosignal average value is 0.9mV, the height of the patient bed is 100cm, and the height of the patient bed is reduced to 100cm-5cm-2cm multiplied by 2=91 cm.
In implementation, the method adjusts the height of the bed where the patient is by setting the preset electrocardiosignal average value, and the mutual induction effect between the electric fields of the wires is generated due to different vertical degrees of the wires of the monitoring equipment and the ground, so that the influence on the monitoring result is caused, and the vertical angle of the wires of the monitoring equipment is increased by reducing the height of the bed where the patient is positioned, so that the influence of the mutual induction effect of the wires is reduced, the occurrence rate of false alarm and false identification is reduced, and the stability of the monitoring environment is further improved.
Specifically, in the step S7, the step of determining the stability of the monitoring environment includes:

Specifically, in the step S8, the step of adjusting the inflation rate of the cuff includes:
Comparing the cuff lateral pressure with the preset pressure;
and if the lateral pressure of the cuff is smaller than or equal to the preset pressure, the inflation rate of the cuff is reduced.
Specifically, the magnitude of the decrease in inflation rate of the cuff is determined by the difference between the preset pressure and the cuff side pressure.
In practice, the preset pressure is typically in the range of 62mmHg,68 mmHg.
Preferably, the preferred embodiment of the preset pressure is 64mmHg.
Specifically, every time the cuff side pressure is less than the preset pressure of 1mmHg, the inflation rate of the cuff is reduced by 0.5mmHg/s, for example, 60mmHg, at which time the inflation rate of the cuff is 25mmHg/s, and the inflation rate of the cuff is reduced by 25mmHg/s-0.5 mmHg/sx4=23 mmHg/s.
