Description

Device for monitoring opening and closing state of rocker switch

Technical Field

The utility model relates to a security protection control technical field especially relates to a device for monitoring the switching state of rocker switch.

Background

School staff need patrol the illuminating lamps, the fresh air systems and the like of all classrooms and offices after leaving school, so that the power utilization safety is ensured, and the energy-saving requirement is met. Many classrooms and offices of many schools are scattered in different buildings, the patrol workload of workers is large, and the workers can leave the schools after the patrol is finished, so that the energy is consumed. In order to reduce workload and improve efficiency, the ideal mode is to automatically detect whether the lighting lamp and the fresh air system of the school classroom are closed or not, and carry out remote control, thereby facilitating remote control and operation of workers.

At present, most of reports about monitoring of illuminating lamps and fresh air systems focus on how to decide the work of the illuminating system or the fresh air system, for example, the work mode of the fresh air system is decided according to the number of people, the brightness is matched and the air quality, and the functions are integrated in the illuminating system and the fresh air system. Many places, including school classrooms, lighting system and new trend system do not have these functions, can not provide the information whether light, new trend system are closed for the staff long-rangely.

The lighting lamp and the fresh air system of the school usually adopt a rocker switch to control the on-off of the power supply. The products of remote control rocker switches exist in the market, but only operation commands can be executed, the remote control rocker switches cannot be detected to be in a closed state or an open state, the situation that the commands are not executed in place cannot be detected, and whether the executed commands really close or open the rocker switches needs manual judgment or confirmation, so that the remote control rocker switches are suitable for places where users stay on the spot when the remote control rocker switches are used, such as bedrooms, and the use requirements of people leaving the spot cannot be met, such as public places like offices, school classrooms, libraries, hotels and cinemas.

In addition, many control switch products need to be installed by removing the original switch, some control switch products even need to process the wall surface, and the original circuit needs to be modified, which needs to be implemented by professional personnel. Some switch control devices are attached to the outer layer of the switch, original circuits can not be modified, but the wanes of the original switch are shielded and cannot be manually operated, even if part of the switch control devices provide alternative manual operation mechanisms, the operation hand feeling is not consistent with the original wanes, and users need to adapt to new devices and change habits.

In the aspect of detecting the on/off of a switch, the conventional reports mainly focus on electromagnetic switching devices such as contactors and circuit breakers, air switches and the like in electric power and electrical equipment, and the existing reports are used for detecting the on/off state or the on/off state of the switch by utilizing electric signals, image information, magnetic field changes and position changes of a switch handle in an original circuit, and are used in places such as substations and the like.

The detection is carried out by utilizing the image information, the technology is complex, the requirement is high, and the cost is high; the magnetic field change is used for detection, so that the device is suitable for large-current occasions and is not suitable for illuminating lamps and fresh air systems; the electric signal in the original line is used for detection, a 220V line needs to be modified, and the construction is troublesome; different from a contactor, a circuit breaker and an air switch, the rocker switch has no brake handle and cannot detect according to the position change of the brake handle.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a safe and reliable, structure meet singly, do not change the seesaw switch monitoring device of the original custom of user, can long-range acquisition seesaw switch's switching state information, can long-range controlling and master the operation result, needn't worry "false" operation that maloperation or action are not in place, satisfy public place user demands such as classroom, library, office.
