The testing helmet is connected with the monitoring center through the second communication module;
the working principle and the beneficial effects of the technical scheme are as follows:
the testing helmet or the protective head cover is internally provided with a physiological health monitoring assembly, and the physiological health monitoring assembly (such as a blood pressure sensor, a heart rate sensor, a blood pressure saturation sensor, a gas sensor and the like) is used for testing a series of indexes of blood pressure, heartbeat, blood oxygen saturation, carbon dioxide concentration in the head cover and the like of a wearer. When the multifunctional protective clothing is used, a test helmet is worn firstly (because different people have different body qualities such as body surface areas, sweating degrees, vital capacity, metabolic capacity and the like, comfortable breathing air quantity and cooling air quantity are different, more importantly, the comfortable feeling is realized, and the physiological indexes are healthy), the test helmet is required to be worn before a user wears the protective clothing, data (such as data for using comfort timely and including blood pressure, heartbeat, blood pressure saturation, oxygen content and the like) are tested, and vital capacity data (air quantity required by a wearer for small-amount exercise, medium-amount exercise and large-amount exercise breathing in work is recorded) are also included so as to be convenient for intelligent distribution; the data is transmitted to a cloud data center (a monitoring center) and is used for controlling a data standard value (a blood pressure standard value) of a control box which is defaulted at ordinary times;
the controller intelligently controls the micro-positive pressure ventilation circulating system (such as adjusting the wind speed) and the second ventilation and exhaust system to work according to the detection result of the physiological health monitoring assembly of the protective clothing and the data transmitted by the helmet for testing and transmitted by the monitoring center (such as software), so that the use comfort and safety are ensured.
Air is introduced and exhausted into the interior of the protective hood through a micro-positive pressure ventilation circulating system, air is introduced and exhausted into the protective suit body through a second air introducing and exhausting circulating system 1, and the protective hood and the protective suit body are respectively ventilated; compared with the existing positive pressure protective clothing, the positive pressure protective clothing is only provided with a ventilation circulating system, air enters from the top of the head and goes out of legs and feet, so that positive pressure large air supply in the hood mask causes triple damage to a wearer, one is that a large amount of rapid air blows the head of the face for a long time to cause vegetative nerve disorder of a person, the other is that eyes are dry, and the noise of the three air affects hearing; the invention can solve the problem and has the advantage of comfortable use;
