在游乐设施信号测量系统中,数据的传输方式常采用有线的传输方式,以保证数据的准确性、可靠性和稳定性。然而在高温场合、野外及条件比较恶劣的环境,待测系统中的某些参数(如温度、压力、应变等)需要实时传输出来给控制中心时,由于输出线路的存在,限制了它在特殊情况下的使用(还包括测量点不易穿线或者处在运动的情况下)。另外,输出线路上不但耗散信号功率,而且易使传感器信号受到外界环境的干扰,甚至线路的长短也会影响测量结果。而传统的遥测系统存在着结构复杂、体积大、耗电大、使用不便等缺陷。在这样的场合根本无法实现信息的有线传输。因此迫切需要一种灵巧、小型、低功耗的新型的无线传感系统。
In the amusement park signal measurement system, the data transmission method often adopts the wired transmission method to ensure the accuracy, reliability and stability of the data. However, in the hot environment, the field and the harsh environment conditions, the system under test some parameters (such as temperature, pressure, strain, etc.) need to be transmitted to the control center in real time, due to the existence of the output line, which limits its special The use of the case (also includes the measuring point is not easy to threading or in the case of exercise). In addition, the output line not only dissipates signal power, but also easy to make the sensor signal by the external environment interference, and even the length of the line will affect the measurement results. However, the traditional telemetry system has the defects of complex structure, large volume, large power consumption and inconvenient use. In such situations, wired transmission of information can not be achieved at all. Therefore, there is an urgent need for a smart, small, low power consumption of the new wireless sensor system.
