The present invention relates to a security supervisory control system control method and particularly to a control method for a security supervisory control system to control remote sensors.
A conventional security system for residence discloses in U.S. Pat. No. 7,113,099 and U.S. Pat. No. 5,689,235 which generally consists of a system host, various types of sensors, monitor video cameras and various types of alarms. These devices are communicated through radio frequency signals. In the past, when the system host is in an alert condition, namely people are absent from the house, commands have to be entered in advance on the keyboard of the system host to make all the sensors and alarms under the control of the system host to enter an alert condition to guard against intruders or detect risky environmental conditions. When the people of the house return or are resting indoors at night, the alarms and sensors cannot be all set ON, otherwise the sensors in the house could be mistakenly triggered to generate a faulty alarm. Hence the system host should be able to selectively actuate the sensors. While such a technique resolves the problem of triggering faulty alarm, it also creates other problems to users. Because the sensors have to be selectively actuated, all the alarms and sensors have be coded and numbered. And the individual number of the alarms and sensors have to be entered on the keyboard of the system host according to requirements so that the computer of the system host can determine which alarms and sensors to be set ON and OFF. In a smaller space in which the number of the alarms or sensors is smaller, a user can set the required sensors based on his/her memory. In the event that the scope of security alarm is greater, and the number of sensors increases. To set the required sensors not only has to rely on user's memory but also has to enter the number of the individual sensors into the system host. It is tedious and takes a lot of time. At present setting a complete security system still has to rely on the technicians of the security service provider. The service fee is charged according to the service content. Altering system procedures incurs additional expense to house owners. Alteration of the security system also cannot be done instantly according to requirement.
The primary object of the present invention is to simplify setting of a security system and reduce setting time and cost. To achieve the foregoing object the invention provides a remote control security supervisory control method adopted for use on a security supervisory control system. The security supervisory control system includes at least a sensor to detect risky conditions in a surveillance scope and a system host to execute a security supervisory control system procedure. The security supervisory control method includes steps of: providing a remote control device controlled at a remote site to output a wake-up signal to the sensor; the sensor received the wake-up signal entering a setting mode from a sleeping mode to change system procedure; the remote control device delivering a command signal through the sensor to the system host to change the existing security supervisory control system procedure to redo setting of the system procedure; the system host received the command signal feeding back a confirmation signal to the sensor to finish alteration of the setting. In addition, after the sensor has received the wake-up signal, it transforms to a first determination signal to be selectively sent to the system host or the remote control device. The system host or remote control device feedbacks a second determination signal to determine whether the sensor to receive the command signal from the remote control device to change the system. By means of the remote control security supervisory control method of the invention users can easily set ON and OFF of the individual sensors through a remote control approach without setting on the system host for the detection scope as the conventional security system does. Hence setting of the security system is greatly simplified. It also requires only a lower technical skill and less time to do the setting.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

In order to prevent the sensors 20 from erroneously entering the setting mode by a signal of a lower power caused by the remote control device 10 due to their being too close to one another, the invention provides two measures to determine which sensor 20 to receive the first command signal 121 from the remote control device 10 thereby to alter the security supervisory control system procedure.

The remote control security supervisory control method of the invention controls the sensor 20 through the remote control device 10. It simplifies the alteration procedure of the conventional security supervisory control system that has to be performed on the system host 30. The remote control device 10 can directly set ON/OFF of alarm function of the individual sensor 20 or set clusters of sensors 20. Thus time and effort for setting the sensor 20 can be reduced. The setting procedure of the sensor 20 is simpler. And users can perform setting immediately according to requirements.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
