In another example, when the group device is controlled by the control system, a user adds a plurality of device names through a group device agent, a client registers a subscription function to a related device service according to the device names, and sets a unique ID to the group, the group device realizes naming assignment of a plurality of devices in a release manner, and the system service updates a plurality of pieces of device attribute information simultaneously through an event mechanism to realize control and monitoring of the group device. As shown in fig. 9, the group device control and monitoring mechanism is implemented, the client CGroupProxy implements a device group control interface through a group control interface of a database service, the database service provides an interface for commands, attribute reading, and attribute writing to the outside, and input parameters of the database service include function attribute names, a device name list, and input parameter values. When a function calls or writes an attribute value, the database issues data to a system service by an event mechanism, and the system service calls related equipment to realize and control functions through a thread pool; when the function calls the write attribute, the database service realizes the reading of a plurality of equipment attribute values through an equipment service process interface and returns the values to the client.
When the control command is issued, the array field comprises a function name, a device name list and an input parameter.
The client agent provides a group control interface to the outside as follows.
// function name input parameter output parameter
a) CDeviceDataListgroup _ command (…); // string-function name, CdivviceData-device name list, CdivviceData-input parameter;
b) void group _ write _ value (…); // string-attribute name, CdviceData-device name List, CdviceData-data value;
c) cdeviceatttrvaluelitlisgroup _ read _ value (); // string-attribute name, CdiviceData-device name list.
The above scheme is merely illustrative of the preferred embodiment, but not limiting. When the invention is implemented, appropriate replacement and/or modification can be carried out according to the requirements of users.
