The invention provides a fault judgment method for a Lora wireless ad hoc network, and relates to the field of communication, in order to solve the problems that after the LoRa wireless ad hoc network breaks down, judgment is difficult, and the operation and maintenance cost and the maintenance difficulty are increased easily, and the method comprises the steps that common fault results and fault causes of the LoRa wireless ad hoc network are classified; a LoRa ad hoc network fault judgment Bayesian network diagram is formed; assigning the probability of each node in the Bayesian network diagram by adopting an expert assignment method; calculating a connection probability and a conditional probability table of each node in the LoRa ad hoc network fault judgment Bayesian network graph; and applying the connection probability and the conditional probability table to a Bayesian network graph to carry out LoRa ad hoc network fault judgment. According to the method, the fault information of the LoRa wireless ad ho
