In the launch vehicle parameter measurement system, the traditional sensor network is connected by cables. With the increase of test points, the use of a large number of cables not only brings excess load and power consumption, but also takes up a lot of cabin space , causing huge trouble for the layout and installation of other equipment in the rocket cabin. In response to the above problems, we propose a CC1310-based wireless sensor network (WSN) design scheme to realize the cableless test system. In this design, the ultra-low-power RF chip CC1310 with a communication frequency band below 1GHz (Sub-GHz) is selected as the sensor network controller, the low-power K-type thermocouple AD8495 is used to collect temperature data, and the lithium battery is used for power supply. The software design implements the periodic sleep and wake-up listening mechanism of sensor nodes, and the master node polls and accesses sensor nodes to obtain the function of status and data. The node low power consumption design is completed and the reliability of the data can be guaranteed. The experimental test shows that the system has a reasonable design, low power consumption, stable and reliable data transmission, and the average energy consumption of the system in working state is 88μA, which can realize long-term measurement of environmental parameters in the rocket cabin.
