Patent ID: 8130094

Claim:
A mistake-proof monitoring method applied to a bedridden care system, wherein the bedridden care system includes a computer, a plurality of transmitters and a warning device, each transmitter includes a device identification code, the computer is coupled to each transmitter and the warning device for receiving messages from and transmitting messages to each transmitter and the warning device respectively and has a healthcare database installed therein for storing the device identification codes of all transmitters and healthcare data lists corresponding to the device identification codes, and each transmitter is coupled to a sensor for receiving a sensing message transmitted from the sensor, encoding the device identification code of the transmitter into the sensing message and then transmitting the sensing message to the computer, the method comprising the steps of: the computer comparing the device identification code encoded in the sensing message with the device identification code stored in the healthcare database, and determining whether or not the sensing message transmitted from one of the transmitter has not been received for a predetermined time or in a predetermined number of times; the computer determining whether or not an ambient datum exists in the sensing message after the sensing message is received; the computer reading the ambient datum existing in the sensing message, and then determining whether or not a numeric value of the ambient data is normal; and the computer determining whether or not a time interval between a current time and a previous time occurring an abnormal situation is beyond a predetermined normal time interval, when the numeric value of the ambient datum is normal.
