More specifically, the touch panel is used to display a parameter index of the air in the gas insulated switchgear installation chamber, which index is displayed in a numerical form. The gas insulated switchgear installation chamber cannot reach the air purification index instantly after being started every day, and a waiting process is required. If the worker enters the air purification apparatus, the air outside the air purification apparatus is brought in, and indoor air flow is caused, thereby further influencing the purification process.
Therefore, the touch screen is arranged outside the installation chamber of the insulation switch installation chamber, before workers enter the installation chamber, whether the indoor air of the insulation switch installation chamber meets the purification standard or not is firstly confirmed, and after the indoor air of the insulation switch installation chamber meets the purification standard, the workers can enter the insulation switch installation chamber to work.
The insulating switch installation room door is further improved, an electromagnetic lock is arranged on the insulating switch installation room door and is controlled by a controller, before a worker enters the insulating switch installation room, identity information and a password which are authenticated in advance need to be input on a touch screen, and if the identity information and the password are input wrongly, the electromagnetic lock keeps the locking state of the insulating switch installation room door; however, even if the input is correct, it is determined in cases: if the air in the insulating switch installation room does not reach the purification standard, the insulating switch installation room door still keeps locked, and the touch screen outputs a warning message; only after identity information, password and the indoor air of insulating switch installation room reach the purification standard, the insulating switch installation room can be opened.
The touch screen is arranged outside the insulation switch installation room, and workers can know the indoor air purification condition at a glance, so that the air pollution of the insulation switch installation room caused by the fact that the workers enter the room without trade is prevented; the insulating switch installation room still is equipped with the electromagnetic lock, only after identity information, password and insulating switch installation room air purification reach preset's standard, the staff can get into insulating switch installation room work, and the indoor air quality of insulating switch installation is guaranteed.
Further, the monitoring host includes: the display, the camera and the touch screen are respectively electrically connected with the network video recorder.
Further, the control unit further includes: the touch screen is also used for storing the received work record input information into the work record memory, and the work record memory is electrically connected with the touch screen.
More specifically, the network video recorder is a Stereobasi graphic brand video recorder with model ST-3308, the video recorder can support a 6TB hard disk for storing video images, the video recorder converts analog images into digital images for storage by adopting H.264 coding, and the network video recorder is electrically connected with the display through a VGA interface or an HDMI interface.
The human-computer interface of the touch screen is provided with a work record filling interface used for registering the time for starting to install the gas insulation switch and the time for finishing the installation of the gas insulation switch, and the interface can be transmitted to the monitoring host, so that the time for installing the gas insulation switch can be seen on the monitoring host, the synchronous display of the work record, the video image and the air parameter of the insulation switch installation chamber on the same screen is realized, the synchronization of three kinds of data is realized, the quality problem is generated subsequently, and the reason is convenient to find.
The embodiments described above are only preferred embodiments of the invention and are not exhaustive of the possible implementations of the invention. Any obvious modifications to the above would be obvious to those of ordinary skill in the art, but would not bring the invention so modified beyond the spirit and scope of the present invention.
