Problems solved by technology

In addition, in most systems, the control function of the computer is limited to the expansion of an operating keyboard as a video matrix switcher / controller. The command control function is not obvious enough, and its core role has not been highlighted. The situation of resources is not suitable, the reason for this situation is that the general function of the video matrix switch / control device is not strong. Especially the upward communication function after the real-time response to the alarm is not strong

specific Embodiment approach

[0041] Such as figure 1 As shown, the Visual basic software and monitoring management scheduling software are loaded into the multi-coal body computer [8] in advance, and the data acquisition and communication alarm software is run in the high-end programmable controller [7]. When the anti-theft alarm sensor triggers the device [ 3] When an alarm signal is detected, the high-end programmable controller [7] responds in real time to the alarm signal generated by the anti-theft alarm sensor trigger device [3], and on the one hand, actively transmits the information to the multimedia computer [8], and the multimedia computer [ 8] Analyze, store, and print this information, and switch the corresponding image to the monitor display device [6]; on the other hand, the high-grade programmable controller [7] directly outputs the corresponding control signal, Start the lighting control device [5]. Realize image, sound and light linkage alarm function.

Abstract

The invention provides a multimedia computer with a programmable controller structure. The multimedia computer consists of three levels, namely on the first level, different types of input / output and control equipment are adopted and belong to conventional configuration; on the second level, a high-grade programmable controller is adopted, has an active communication function so as to be connected with the equipment of the first level easily and can upwards transmit an alarm signal in real time once an alarm signal is generated; and on the third level, the multimedia computer is adopted, runs system monitoring, scheduling and managing software under the support of tool software, such as Windows, VisualBasic and the like, and finishes functions of monitoring closed circuit televisions, processing anti-theft alarm and the like; and works of a foreground and a background can be realized.

Description

technical field [0001] The invention is a multimedia computer with a programmable controller structure. Background technique [0002] The existing security system structure is centered on the manual / automatic video sequence switcher or matrix video switcher / controller to realize the switching selection of video signal input and the control of the up, down, left, right and rotation motion of the installed camera pan / tilt. Control the zoom lens of the camera, control the wiper, fan, heating defroster, etc. inside the camera cover, specify the monitor for displaying images, receive alarm input signals from various sensors in real time, and generate Alarm signal output, etc.; all switching / control actions are realized through panel operation or control keyboard. The security system introduced in recent years has gradually introduced microcomputers for video image signal processing and sound prompts; however, the real-time communication between the computer and the alarm signal ...
