The safety of individuals working at height is currently achieved through a body harness and lanyard. Protection against organ damage is through a shock-absorbing mechanism; stitching in the lanyard to create pleats of material, which when subjected to an impulsive force causes the stitching to break progressively resulting in attenuation of body momentum. New legislation requires the lanyard to withstand harsh cutting tests to avoid the risk of failure in use. Current weaving technology precludes the use of heavier, inflexible fibres and fabrics as narrow-fabric looms are not robust enough to weave the weight and type of fabric required without destruction of the loom lifting mechanisms. The objective is to investigate the feasibility of an innovative economic retrofit which will use electronics and embedded software to control servo motors to perform the lifting operation to produce a lanyard which is lighter and functionally superior to metal alternatives in conforming to legislation.

目前，高空作业人员的安全是通过身体安全带和系索来实现的。防止器官损伤是通过减震机制;在挂绳中缝合以产生材料褶皱，当受到冲击力时，导致缝合逐渐断裂，从而导致身体动量衰减。新的立法要求挂绳承受苛刻的切割测试，以避免使用失败的风险。目前的织造技术不允许使用较重的、不灵活的纤维和织物，因为窄幅织物织机不够坚固，无法在不破坏织机升降机构的情况下织造所需重量和类型的织物。其目的是研究一种创新的经济改造的可行性，该改造将使用电子和嵌入式软件来控制伺服电机以执行提升操作，从而生产出更轻且在符合法规方面优于金属替代品的功能上级的挂绳。
