The pressure sensors 400 are divided into four groups, which are respectively located at the upper end, the lower end, the left end and the right end of the inflatable capsule 100, each group has 2 or more pressure sensors 400, and each group of pressure sensors 400 is set to have a gas pressure set value of X at each point inside the inflatable capsule 100 in an initial state.
The outer windshield comprises the following use steps:
step S1: the rail transit vehicle is pre-inflated before running. The inflatable capsule 100 of the outer windshield of the rail transit vehicle is pre-inflated, so that the inflatable capsule 100 has a constant initial air pressure value and keeps a constant distance value connected to the vehicle body.
The control system controls the inflation system to pre-inflate the inflatable capsule 100 of the external windshield, and the pressure sensor inside the inflatable capsule 100 detects the pressure of the inflated gas so that the pressure value of the gas inside the inflatable capsule 100 reaches an initial set value X; meanwhile, the distance between the two car bodies on the two sides of the inflatable capsule 100 is detected by the position sensors 200 which are positioned on the inner side and the outer side of the inflatable capsule 100 and connected between the two car bodies of the rail transit car, so that the distance value between the two car bodies connected with the inflatable capsule 100 reaches the initial distance set value A. And only under the condition that the gas pressure value is X and the distance value is A, controlling the rail transit vehicle to start running by the control system. When the gas pressure value in the pre-inflation process exceeds the initial pressure set value X, the control system controls the inflation system to be closed, the exhaust system is opened, and the pressure of the inflatable capsule 100 is regulated until the gas pressure value in the inflatable capsule 100 reaches the initial pressure set value X.
Step S2: the position sensor detects an inter-vehicle distance. The first position sensor 301, the second position sensor 302 and the third position sensor 303 in the position sensor 300 realize multipoint real-time monitoring of the distance value between the car bodies on two sides of the rail transit car in operation, and feed back the distance value information to the control system in real time.

The first position sensor 301, the second position sensor 302 and the third position sensor 303 of the position sensor 300 for real-time position detection are respectively located inside the inflatable capsule 100, and the first outer side of the inflatable capsule 100 and the second outer side of the inflatable capsule 100 are used for real-time distance detection. To achieve accurate detection of the position between the vehicle body and the vehicle body, the position sensors 300 at each end of the inflatable bladder 100 are in one group, with a total of multiple groups, preferably 4 groups.
Step S3: the pressure sensor detects the outer windshield gas pressure. The pressure sensor 400 realizes multipoint real-time monitoring of the gas pressure value inside the inflatable capsule 100 during operation of the rail transit vehicle, and feeds back the information of the gas pressure value to the control system in real time.
The pressure sensors 400 are used for detecting the gas pressure inside the inflatable capsule 100 in real time, for accurately feeding back the pressure inside the inflatable capsule 100 under each running state of the vehicle body, the pressure sensors are respectively arranged at the upper end part, the lower end part, the left end part and the right end part of the peripheral wall of the inflatable capsule 100 connected to the vehicle bodies on two sides, the gas pressure inside the inflatable capsule 100 changes when the inflatable capsule is stretched or compressed, specifically, the local pressure increase and the local pressure decrease are shown, the pressure sensors 400 adopt multiple groups, each group is not less than 2 in number, namely, each end part is distributed with not less than 2 pressure sensors 400, and 3 pressure sensors are preferentially and equidistantly arranged.
Step S4: the inflation port and the exhaust port are opened or closed according to the position sensor and/or the pressure sensor. The control system inflates or deflates the inflatable capsule 100 according to the feedback information of the position sensor 300; the control system inflates or deflates the inflatable capsule 100 according to the feedback information of the pressure sensor 400; the control system inflates or deflates the inflatable capsule 100 based on the feedback information from the position sensor 300 and the pressure sensor 400.
When the rail transit vehicle runs through a non-linear section or a section with high and low drop, the position and the distance between the vehicle body and the vehicle body are changed, when the vehicle body stretches the inflatable capsule 100 in the running process, a first position sensor 301, a second position sensor 302 and a third position sensor 303 in the position sensor 300 for real-time position detection are respectively positioned in the inflatable capsule 100, and the distance is detected in real time on a first outer side of the inflatable capsule 100 and a second outer side of the inflatable capsule 100. Taking the upper left end of the inflatable capsule 100 as an example for description, the first position sensor 301, the second position sensor 302 and the third position sensor 303 respectively detect the distance values a1, a2 and A3 of the upper left end of the inflatable capsule 100, feed back the information of the distance values detected in real time to the control system, compare the actual distance value information fed back by the position sensor 300 with the theoretical distance average value a after performing average arithmetic calculation by the control system, and when the actual distance average value is not less than 110% of the initial distance set value a, the control system controls the inflation system to be opened, and inflates the interior of the inflatable capsule 100 through the inflation inlet 500.
Meanwhile, when any one of the distance values A1, A2 and A3 detected by the first position sensor 301, the second position sensor 302 and the third position sensor 303 arranged between any two end positions of the upper left end portion, the upper right end portion, the lower left end portion and the lower right end portion is larger than or equal to 130% of the initial distance set value A, the control system controls the inflation system to be started, and the interior of the inflatable capsule 100 is inflated through the inflation inlet 500. Meanwhile, when any one of the distance values A1, A2 and A3 detected by the first position sensor 301, the second position sensor 302 and the third position sensor 303 arranged between any two end positions of the upper left end portion, the upper right end portion, the lower left end portion and the lower right end portion is compared with the initial distance set value A, the actual distance average value is larger than 90% of the theoretical distance average value A, and the actual distance average value is smaller than 100% of the theoretical distance average value A, the control system controls the inflation system to be closed, and the inflation inlet 500 does not inflate the interior of the inflatable capsule 100 any more.
As the vehicle body compresses the inflatable bladder 100 during operation, the control system controls the exhaust system to open, and exhausts excess high-pressure gas inside the inflatable bladder 100 through the exhaust port 600.
The inflation or the exhaust of the inflatable capsule 100 can not be performed simultaneously, that is, the exhaust port of the exhaust system must be closed when the inflation system inflates the inflatable capsule 100 through the inflation port; and vice versa. According to the actual operation condition of the rail transit vehicle, the interior of the inflatable capsule 100 is inflated or exhausted in a reciprocating manner, so that the inflatable capsule 100 always meets the use requirement of the vehicle body in the operation process.
