In the measurement of environmental parameters of rocket cabin, the traditional wired measurement method will increase the overall weight of the rocket cabin. Therefore, it is of great significance to use wireless sensor network to replace the traditional wired measurement method to reduce the weight of the rocket cabin. Aiming at the above problems, a wireless sensor network based on AD hoc network protocol is proposed, which is based on wireless transceiver chip CC1310 to build a wireless sensor network, selects 915 MHz frequency band as the data transmission channel, and designs an AD hoc network protocol, the wireless sensor nodes in the network only need to keep the same static address as the collector. When the node is powered on, it can automatically join the network, and the collector will assign a unique dynamic address to each node, adds CSMA/CA mechanism to prevent channel data collision, and is successfully applied to this wireless sensor network. The test results show that: when the data transmission rate of the wireless sensor network is 250 Kbps and the signal sampling frequency is 100 SPS, the wireless sensor node can automatically join the network created by the collector after being powered on, and successfully upload the sensor data according to the time interval configured by the collector, and no node data loss within the range of 10 m. It can meet the measurement needs of environmental parameters in the capsule of the launch vehicle.
