A human-shaped target damage parameter testing device is shown in figure 1 and comprises an equivalent human-shaped target, human organ sensors at different parts, a multi-path data acquisition and storage module and a data processing module.
The human organ sensor is designed according to the shape and the size of key organ parts (including a head, a lung, a heart, a liver, a stomach, a large intestine, arms, legs and the like) to be tested and is fixed at the corresponding part of the equivalent human-shaped target.
As shown in fig. 2, the organ sensor includes a substrate (the substrate may be a PET film, etc.), and positive and negative electronic circuits printed thereon at equal intervals, wherein the positive and negative electronic circuits of each organ sensor have shapes and sizes corresponding to those of the simulated organ; both ends of each positive electron circuit of each human organ sensor are connected to the same anode, and both ends of each negative electron circuit are connected to the same cathode; the positive electron circuit and the negative electron circuit are insulated from each other.
The division of the body organ sensors is performed according to the area occupied by the shape and size of the organ itself, as shown in fig. 3, when two organs are overlapped, for example, the left lung a and the right lung C are overlapped with the heart, the overlapped area constructs a single body organ sensor, and the sensors B, D, E are obtained respectively, and the rest of the left lung a and the right lung C except the overlapped area is used as another single body organ sensor.
The positive and negative outputs of each human organ sensor are led out to a signal output port at one side of the human organ sensor. When the fragments or the bullets pass through a certain human organ sensor test target surface, the positive and negative electrode electronic circuits which are alternately arranged in the human organ sensor are conducted and are in short circuit by the fragments or the bullets, and an over-target signal is generated. The size resolution is the distance between the adjacent anode electronic circuit and the cathode electronic circuit.
In a certain distance from the explosive core, attaching each human organ sensor to a key organ part to be tested of the equivalent humanoid target towards the explosive core, performing self-defined matching on an output port of each testing area of the human organ sensor and input ports (with serial numbers A, B and C \8230; and the like) of a multi-path data acquisition and storage module, and defining a matching rule into a data processing module; when the fragments/pills pass through the human organ sensor, current signals are generated, the current signals are collected and stored by the multi-path data collecting and storing module and are sent to the data processing module in a wireless or wired mode, and according to the serial numbers of the current signals generated when the fragments/pills pass through the human organ sensor, which human organ the fragments/pills are invaded through can be calculated.
As shown in FIG. 4, each human organ sensor can be arranged in the human equivalent target in multiple layers at equal intervals, the distance between two adjacent layers is set as l, according to the response condition of each layer of human organ sensor, if the human organ sensor has response before the kth, the depth of the broken pieces penetrating into the humanoid target is calculated as (k-1) l. The human-shaped target damage parameters tested based on the method can provide criterions for the evaluation of the human target damage.
The multi-path data acquisition module: when the fragments or the shots pass through the human organ sensor, the fragments or the shots serve as conductors to conduct positive and negative electronic circuits alternately arranged in the region where the human organ sensor is located to generate target passing signals, multi-path data acquisition and storage are carried out after signal conditioning, as shown in fig. 5, an electrode output port of a negative electronic circuit module and electrode output ports of a plurality of positive electronic circuit modules of the human organ sensor are connected with a signal input port of the multi-path data acquisition and storage module in a self-defined sequence matching mode, multi-path target passing signal information is processed by the multi-path data acquisition and storage module to obtain target passing signal partition number information and target passing signal time information, the data are stored as files, and the data are read by the data processing module.
The data processing module: based on QT5.12.0 platform programming, a modularized compiling method is adopted, a dynamic loading mode is adopted, data transmission adopts a data flow idea, and the data processing module interface is shown in figure 6 and comprises data reading and generating, result displaying, waveform displaying, parameter setting and the like.
When the multi-path acquisition module transmits the partition number information of the over-target signals and the time information of the over-target signals to the data processing module, the calculation process is as follows:
the output ports of all human organ sensors (including the head, the lung, the heart, the liver, the stomach, the large intestine, the arms, the legs and the like) are matched with the input ports (with the serial numbers A, B, C, 8230and the like) of the multi-path data acquisition and storage module in a self-defining way, the matching is defined into the data processing module, and when a fragment or a bullet hits an organ area of the human organ sensors, the data processing module can calculate the position of a target organ in the fragment according to the serial number information responded by the ports of the multi-path data acquisition and storage module, and the specific figure 7 shows that.
The invention can also calculate the depth of the broken piece damaging the corresponding organ of the humanoid target, which specifically comprises the following steps:
the invention arranges a plurality of human organ sensors, arranges each human organ sensor in an equivalent humanoid target at a plurality of intervals, wherein the number of the output ports of the human organ sensors in the first layer, which are connected with the input ports of the multi-path data acquisition and storage module, is A 1 ～x 1 The output port of the nth layer of human organ sensor is connected with the input port of the multi-path data acquisition and storage module and is A n ～x n The number of input ports of the multi-path data acquisition and storage module is A in total 1 ～x n . As shown in fig. 8. When the broken pieces penetrate through the human body to the kth layer, namely every A in the front of the human body organ sensor at the kth layer i ～x i If all the ports (i is more than or equal to 1 and less than or equal to k) have over-handle signal responses, the data processing module resolves the fragmentsThe penetration depth of the human body is (k-1) l.
