1. A method of controlling an insulin patch performed by an insulin patch control device comprising: an insulin patch including an insulin pump and a blood sugar sensor; and a computing device that communicates with the insulin patch through a network, the method comprising the steps of:
obtaining, by the insulin patch, blood sugar information from the blood sugar sensor;
transmitting the blood sugar information obtained by the insulin patch to the insulin patch control device to input the same to a first neural network of the computing device;
estimating pump parameters of the insulin patch based on output data from the first neural network;
simulating the insulin patch by selecting one of the estimated pump parameters;
in a case where an expected blood sugar level exceeds an effective range as a result of simulation, determining that the estimated pump parameter is not effective, and selecting another pump parameter from among the estimated pump parameters; or re-estimating a pump parameter;
in a case when an expected blood sugar level exceeds an effective range as a result of simulation, transmitting a control signal to the insulin patch;
in a case where the insulin patch does not receive the control signal for a specified time due to communication failure of the network or a problem of the insulin patch control device,
estimating a pump parameter of the insulin patch through an algorithm based on the blood sugar information independently obtained by the insulin patch; and
transmitting a control signal to the insulin pump based on the estimated pump parameter.
