[0002] At present, the control and operation between devices requires the control device and the controlled device to agree on the control code in advance. For example, for a controlled air conditioner, its control code: 1 means the air conditioner is on, 2 means the air conditioner is off, 3 means the temperature plus 1 degree, 4 means that the temperature minus 1 degree, ... If a control device needs to control the air conditioner, the control device is required to know in advance that the controlled device is an air conditioner, and know each control code and meaning of the air conditioner, so that it can control the air conditioner. The air conditioner performs related control and operation. When the function of the air conditioner is upgraded, for example, a function is added, the working mode is set to heating mode, and the control code is 8. At this time, if the control device does not perform the corresponding function upgrade, then Unable to generate control code 8, unable to control upgraded equipment, let alone control unknown equipment

The invention discloses a method for realizing equipment mutual control through equipment self-description. The method uses a self-describing file to represent equipment and allows equipment to submit the self-describing file to be recognized and understood by other equipment, thereby realizing equipment mutual control and operation. The invention relates to a self-describing method for interconnection equipment. According to the method, interconnected equipment describes resources and functional service interfaces of the interconnected equipment. During interconnection, the equipment can be recognized and understood by other equipment by submitting the equipment description of the equipment so as to carry out related functional operation and call services. Thus, interconnected equipment does not need to clearly know functions and operations of the connected equipment before interconnection, and can carry out mutual control and operation according to equipment description by acquiring mutual equipment description after interconnection.
Description
technical field [0001] The invention relates to a method for realizing mutual control of devices through self-description of devices in a device interconnection network involved in environments such as enterprises, public places, individuals and families. technical background [0002] At present, the control and operation between devices requires the control device and the controlled device to agree on the control code in advance. For example, for a controlled air conditioner, its control code: 1 means the air conditioner is on, 2 means the air conditioner is off, 3 means the temperature plus 1 degree, 4 means that the temperature minus 1 degree, ... If a control device needs to control the air conditioner, the control device is required to know in advance that the controlled device is an air conditioner, and know each control code and meaning of the air conditioner, so that it can control the air conditioner.
