Abstract

There is provided a system for servicing and maintaining heat supply equipment which ensures reliable analysis and high efficiency. Heat supply equipment 1 is composed of a control unit 5 to be attached to the heat supply equipment 1, and an equipment-side modem 6 for mediating the control unit 5 and a communication line 4. A management station 3 is composed of a management unit 7 for managing the heat supply equipment 1, and a station-side modem 8 for mediating the management unit 7 and the communication line 4. Upon reception of abnormality occurrence data sent from the control unit 5, the management unit 7 further receives detailed information data on an abnormality of the heat supply equipment 1 from the control unit 5, analyses by itself the received detailed information data, and creates recovery data for recovering the heat supply equipment 1 from the abnormality.

Claims

1. A system for servicing and maintaining heat supply equipment, established at least between one or more equipment sites that have heat supply equipment and conclude a servicing and maintenance contract regarding the heat supply equipment, and a management station that performs servicing and maintenance of the heat supply equipment in an area in which the equipment sites are located, the system being established through use of a communication line,

the heat supply equipment comprising:

a control unit to be attached to the heat supply equipment; and

an equipment-side modem for mediating the control unit and the communication line,

the management station comprising;

a management unit for managing the heat supply equipment; and

a station-side modem for mediating the management unit and the communication line, wherein

upon reception of abnormality occurrence data sent from the control unit, the management unit further receives detailed information data on an abnormality of the heat supply equipment from the control unit, analyses by itself the received detailed information data, and creates recovery data for recovering the heat supply equipment from the abnormality.

2. The system for servicing and maintaining heat supply equipment as defined in claim 1, wherein

the recovery data is data regarding recovery instruction information for instructing procedures of recovering the heat supply equipment, and the control unit, upon reception of the recovery data regarding the recovery instruction information from the management unit, displays the recovery instruction information based on the recovery data on a display section provided in the control unit.

3. The system for servicing and maintaining heat supply equipment as defined in claim 1, wherein

the recovery data is data regarding recovery instruction information for instructing procedures of recovering the heat supply equipment, and the management unit sends the recovery data regarding the recovery instruction information to a portable terminal carried by a maintenance man by wireless communication means.

4. The system for servicing and maintaining heat supply equipment as defined in claim 3, wherein

the management unit collects location information transmitted by the portable terminal and determines the maintenance man who can recover the heat supply equipment fastest.

5. The system for servicing and maintaining heat supply equipment as defined in claim 1, wherein

the recovery data is data regarding change in setting values and the like of the heat supply equipment, and the control unit, upon reception of the recovery data regarding the change in setting values and the like, changes setting values and the like of the heat supply equipment based on the recovery data.

6. The system for servicing and maintaining heat supply equipment as defined in claim 1, wherein

the management unit stores readable data on a maintenance manual.

7. The system for servicing and maintaining heat supply equipment as defined in claim 1, wherein

the management unit has a function to transfer the received abnormality occurrence data to a management center supervising a plurality of management stations including the management station through the communication line.
