  The present invention relates to a remote service system and a service method for an automatic analyzer, and more particularly, to a remote service system for an automatic analyzer that is a main device that uses a pure water production apparatus as an auxiliary device.

  Conventionally, information collection by an automatic analyzer is performed as shown in the following Patent Documents 1 to 3. For example, in Patent Document 1, an automatic analyzer is connected to an operation information analysis center by a line via a repeater. A configuration is disclosed in which operation information of an automatic analyzer is once accumulated in a repeater, an urgency level is determined, and is appropriately transmitted to an information analysis center according to the urgency level.

  Patent Document 2 describes that a result of data obtained by an automatic analyzer is judged and warning information or the like is transmitted to a service base through a communication line.

  Furthermore, Patent Document 3 describes that information from a plurality of devices installed at remote locations is determined by determining the contents of a contract and determining whether or not to connect remotely to suppress useless communication. In the above patent documents, there is no example in which the information of the auxiliary device is taken into account and used for the analysis of the device abnormality of the automatic analyzer which is the main device.

  An example of collecting information on a pure water production apparatus can be found in Patent Document 4. However, the obtained information is independently transmitted to a remote monitoring center and is not used for abnormality analysis of other devices such as an automatic analyzer. Patent Document 5 discloses that pure water information of a pure water production apparatus is input to a terminal of an automatic analyzer. However, the information includes supply volume and discharge volume and does not include water quality data.
