具体地，在上述第一传感纱线31和第二传感纱线32之间存在一个交叉点时，若电池表面设置有多个织物传感器11时，具体的实现方式可以参照图3、图4、和图5是，图3为本申请提供的一种传感纱线交叉示意图，图4为本申请提供的第一种织物传感器布局示意图，图5为本申请提供的第二种织物传感器布局示意图。Specifically, when there is an intersection between the above-mentioned first sensing yarn 31 and the second sensing yarn 32, if multiple fabric sensors 11 are provided on the battery surface, the specific implementation method can refer to Figure 3 and Figure 3. 4. and Figure 5 are, Figure 3 is a schematic diagram of a sensing yarn intersection provided by this application, Figure 4 is a schematic layout diagram of the first fabric sensor provided by this application, and Figure 5 is a second fabric sensor provided by this application. Layout diagram.
图3中，假设多个横向的传感纱线为第一传感纱线31，多个竖向的传感纱线为第二传感纱线32，可见，多个第一传感纱线31之间相互平行，多个第二传感纱线32之间相互平行，且每相邻两个传感纱线之间均存在一定的距离，具体地，距离不小于预设距离，从而保证第一传感纱线31和第二传感纱线32之间只存在一个交叉点。In Figure 3, it is assumed that the plurality of transverse sensing yarns are the first sensing yarns 31, and the plurality of vertical sensing yarns are the second sensing yarns 32. It can be seen that the plurality of first sensing yarns 31 are parallel to each other, multiple second sensing yarns 32 are parallel to each other, and there is a certain distance between every two adjacent sensing yarns. Specifically, the distance is not less than the preset distance, thereby ensuring There is only one intersection point between the first sensing yarn 31 and the second sensing yarn 32 .
在具体应用中，可参照图4和图5，其中，图4中，假设成行排布的为第一传感纱线31，成列排布的为第二传感纱线32，第一传感纱线31和电池的一侧平行，第二传感纱线32和电池的另一侧平行，且与第一传感纱线31垂直，此时，每个交叉点作为一个点式传感器。其中，在编织方式上，可以是将多条传感纱线内嵌到编织布中。图5中，第一传感纱线31可以斜向电池边布局，斜角度不限定，布局为第一传感纱线31为左斜向格局，第二传感纱线32为右斜向格局。同样的，每个交叉点作为一个点式传感器，在编织方式上，可以是将多条传感纱线内嵌到编织布中。In specific applications, reference can be made to Figures 4 and 5. In Figure 4, it is assumed that the first sensing yarns 31 are arranged in rows, and the second sensing yarns 32 are arranged in columns. The sensing yarn 31 is parallel to one side of the battery, and the second sensing yarn 32 is parallel to the other side of the battery and perpendicular to the first sensing yarn 31. At this time, each intersection serves as a point sensor. Among them, in terms of the weaving method, multiple sensing yarns can be embedded into the woven cloth. In Figure 5, the first sensing yarn 31 can be arranged diagonally toward the battery side, and the angle of inclination is not limited. The layout is that the first sensing yarn 31 is in a left diagonal pattern, and the second sensing yarn 32 is in a right diagonal pattern. . Similarly, each intersection serves as a point sensor. In the weaving method, multiple sensing yarns can be embedded into the woven fabric.

One end of the voltage dividing resistor in the circuit is connected, and the other end of the voltage dividing resistor is connected to a low-voltage power supply or a constant current source (it can also be understood that the first sensing yarn 31 is connected to the positive electrode). The plurality of second sensing yarns 32 are connected with the same polarity. For example, when they are all connected to their corresponding voltage dividing circuits, the second sensing yarns 32 are all grounded (can also be understood as the second sensing yarns 32 are connected to the negative pole). Then, through the connection relationship of each connection and the measured resistance value, it can be determined which intersection point causes the deformation, that is, where the bulge occurs in the battery.
综上，本实施例中的方式可以实现对电池表面的多个位置进行测量的功能，且实现方式简单可靠。In summary, the method in this embodiment can realize the function of measuring multiple positions on the battery surface, and the implementation method is simple and reliable.
