Detailed description of the invention
As shown in Figure 1: a kind of Watt-hour meter 1 facilitating reading at night, including kilowatt-hour meter 1 body, on the eyeglass 2 of kilowatt-hour meter 1, the reading around kilowatt-hour meter 1 is provided with ring-type LED 3, the mirror lid 4 hinged with kilowatt-hour meter 1 side by a side it is additionally provided with on the whole at eyeglass 2, described mirror lid 4 rotates by means of motor 5 folding of one end, and described motor 5 and LED 3 are controlled by the control unit being positioned at kilowatt-hour meter 1 side.Described control unit includes: touch sensor 6, single-chip microcomputer, first electric-controlled switch the 7, second electric-controlled switch the 8, first power supply 9, second source 10 and the first limit switch 11 and the second limit switch 12 being provided with in the rotational travel of mirror lid 4.
As shown in Figure 2: the positive pole of described first power supply 9 is divided into circuit 1 and circuit 2 14 after being connected by wire and the first electric-controlled switch 7, described circuit 1 is by being connected with the first power supply 9 negative pole after the first limit switch 11 and motor 5, described circuit 2 14 passes through the LED 3 negative pole the most also with the first power supply 9 and is connected, and described first limit switch 11 and motor 5 are in series；The negative pole of described second source 10 by after the second electric-controlled switch 8 with by being connected before motor 5 and by the circuit 1 after the first limit switch 11, the positive pole of described second source 10 is connected with by the circuit 1 after motor 5 after passing through the second limit switch 12.The described outfan of touch sensor 6 is connected with the access port of single-chip microcomputer, and the outfan of described single-chip microcomputer connects respectively at the first electric-controlled switch 7 and the second electric-controlled switch 8.Described mirror lid 4 touches the first limit switch 11 when turning to eyeglass 2 in 180 degree angles after opening, described mirror lid 4 touches the second limit switch 12 after closing.Described touch sensor 6 is positioned at below kilowatt-hour meter 1, and the height on its distance ground is 1 to 1.7 meters.
nullAs shown in Figure 2: the first electric-controlled switch 7 is normal open switch，Second electric-controlled switch 8 is normally closed switch，After mirror lid 4 covers, the second limit switch 12 is opened，When mirror lid 4 rotate be 180 degree of angles as eyeglass 2 when the first limit switch 11 open，Mirror lid 4 is both of which Guan Bi when other states，The concrete reading operating process of this kilowatt-hour meter 1 is: at night，Touch with finger and be positioned at the touch sensor 6 below kilowatt-hour meter 1，Touch sensor 6 converts a signal into the signal of telecommunication after signal being detected and passes to single-chip microcomputer，Single-chip Controlling the first electric-controlled switch 7 closes，Second electric-controlled switch 8 is opened，Now motor 5 and LED 3 are all energized，Motor 5 rotates forward band index glass lid 4 and opens，After mirror lid 4 is opened, the second limit switch 12 closes，When the position that mirror lid 4 turns to eyeglass 2 is 180 degree of angles，First limit switch 11 is opened，Although because now the second limit switch 12 closes，But the second electric-controlled switch 8 is opening，So motor 5 stops operating；After reading is complete, finger leaves touch sensor 6, and touch sensor 6 sends the signal of telecommunication to single-chip microcomputer, Single-chip Controlling the first electric-controlled switch 7 is opened, second electric-controlled switch 8 closes, and now LED 3 is extinguished, owing to now the second limit switch 12 is in closure state, so motor 5 inverts under the rotation of second source 10, making mirror lid 4 rotate backward, after mirror lid 4 covers eyeglass 2, the second limit switch 12 is opened, motor 5 stops operating, and so completes reading and is also covered on eyeglass 2 by mirror lid 4.
Use and have the beneficial effects that produced by technique scheme: on kilowatt-hour meter, 1, be provided with the Jing Gai for covering eyeglass, the strong surface cleanness that ensure that eyeglass, prevent eyeglass damaged, and the unlatching of this Jing Gai only just can need to automatically turn on finger contact touch sensor, read finger touch sensor after reading, then Jing Gai can close automatically, operates very convenient；2, more weak at night, contact touch sensor with finger when of needing to carry out reading, Jing Gai opens, and the ring-type LED on eyeglass is opened simultaneously, is illuminated by reading, facilitates staff to read.
