Abstract
The utility model discloses a network intelligent control system of a multi-media classroom. The system comprises a single chip microcomputer, wherein a main controller and a projector are connected to the single chip microcomputer, a luminance sensor is connected to the single chip microcomputer and arranged in the front of the projector, a main power supply control circuit is connected to the single chip microcomputer, and the output of the main power supply control circuit controls the automatic switching of a power supply. The illumination can be detected timely, the service life of bulbs can be determined in accordance with the illumination of the projector, backup bulbs can be purchased timely, and the effect on teaching due to the fact that bulbs cannot be replaced timely is avoided. The opening/closing of the power supply of the projector can be determined in accordance with the illumination of the projector, the main controller instructs the single chip microcomputer, the main power supply control circuit controls the automatic switching of a power supply, site inspection of persons is not required and the time and the labor are saved.
Description
Technical field
The utility model relates to a kind of multi-media classroom network control system, especially a kind ofly can judge the use state of projector and the life-span of bulb according to projector light source brightness, and can automatically be controlled by master controller the multi-media classroom network intelligence control system of general supply.
Background technology
At present, the multi-media classroom network is equipped with the center-control terminal, include to control and use single-chip microcomputer, be connected to master controller, computing machine, teaching display device (as projector, large screen television) and signal input device (as video presenter, set-top box, projection screen lifting port, the network port, VGA port, video port, audio port, power port etc.) with single-chip microcomputer, the center-control terminal is divided into unit control type and network controllable type.Existing single-chip microcomputer can only receive the instruction that network transmits, and realizes the simple function of controlling of projector power switch, and can not the execution result of instruction be fed back.Need the teaching equipment maintainer often to arrive on-the-spot the tour, confirm the instruction implementation effect, waste time and energy; Can't judge the serviceable life of projector bulb, often can not purchase in advance the bulb spare part, often delay the use of projector because can not in time more changing the bulb, teaching is impacted.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical matters of prior art, providing a kind of can judge the use state of projector and the life-span of bulb according to projector light source brightness, and can automatically be controlled by master controller the multi-media classroom network intelligence control system of general supply automatic switch.
Technical solution of the present utility model is: a kind of multi-media classroom network intelligence control system, single-chip microcomputer is arranged, be connected to master controller and projector with single-chip microcomputer, it is characterized in that: be connected to single-chip microcomputer the luminance sensor that is placed in the projector front, also be connected to the general supply control circuit with single-chip microcomputer, automatic power switch is controlled in the output of general supply control circuit.
The utility model is to be provided with the luminance sensor that joins with single-chip microcomputer before projector, can immediately detect the brightness of projector, can judge according to the brightness of projector the serviceable life of bulb on the one hand, be convenient in time purchase spare bulb, avoid the impact because can not in time more changing the bulb teaching is caused; Can judge according to the brightness of projector on the other hand whether the power supply of projector closes, and can assign instruction to single-chip microcomputer by master controller, control by the general supply control circuit and close the general supply automatic switch, the personnel that need not are on-the-spot to make an inspection tour, time saving and energy saving.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: same as the prior art, single-chip microcomputer is arranged, be connected to master controller and projector with single-chip microcomputer, to be connected to single-chip microcomputer the luminance sensor that is placed in projector front (projection screen rear) with the prior art difference, also be connected to the general supply control circuit with single-chip microcomputer, automatic power switch is controlled in the output of general supply control circuit.The general supply control circuit can be the control circuits such as relay, and the length of relay is closed contact and is connected in the general supply loop as automatic power switch.
Principle of work:
1. can by manually controlling total power switch, open general supply, projector power supply etc.;
2. luminance sensor detects the display brightness of projector immediately, at this moment, single-chip microcomputer is drawn brightness curve and sends measurement data by LAN (Local Area Network) to master controller according to built-in embedded software, master controller is according to measurement data, judge whether projector needs it is safeguarded, whether need to be equipped with bulb, and show by the gui interface of controlling software, the system maintenance personnel can monitor the equipment state in all classrooms by software interface; Master controller can judge according to the display brightness of projector also whether projector is in off-mode, if not shutdown, first send shutdown command to projector, projector shuts down and carries out cooling, single-chip microcomputer is after waiting for that projector is cooling and completing, send instruction to the general supply control circuit, the general supply control circuit length of pilot relay closes the contact disconnection, to cut off general supply.
Claims (1)
1. multi-media classroom network intelligence control system, single-chip microcomputer is arranged, be connected to master controller and projector with single-chip microcomputer, it is characterized in that: be connected to single-chip microcomputer the luminance sensor that is placed in the projector front, also be connected to the general supply control circuit with single-chip microcomputer, automatic power switch is controlled in the output of general supply control circuit.
