Embodiment Construction

[0009] Such as figure 1 , figure 2 As shown, an intelligent master key for electric industry includes a key body 1 and a data display part arranged in the key body. The data display part includes a power supply 5, a photoelectric counting touch mechanism, a counting chip and a counting display mechanism 4. The photoelectric counting and triggering mechanism includes a pinball 2 arranged on the key body 1, and a push rod 3 connected with the pinball 2. The push rod 3 moves and touches the counting chip to make the infrared light-emitting diode emit infrared light.

[0010] After the key is inserted into the lock hole, when the marble on the key body touches the lock body, under the pressure of the lock hole, it will move inward along the limit hole, push the push block, touch the counting chip, and make the infrared The light-emitting diode emits infrared light. When the phototransistor VT1 receives the infrared light from the infrared light-emitting diode VD1, its bright cur...

Abstract

The invention discloses an intelligent master key for electric undertaking, comprising a key body and a data display part arranged in the key body. The data display part comprises a power supply, a photoelectric counting touch mechanism, a counting chip and a counting display mechanism, wherein the photoelectric counting touch mechanism comprises a hoodle arranged on the key body, and a push rod connected with the hoodle; and the push rod moves the touch counting chip so that an infrared emitting diode transmits infrared rays. In the invention, due to the data display mechanism arranged in the key body, the evidence for using once can be displayed on the key after the master key is used once, and then the evidence is well recorded. Then the using frequency of the master key can be known by the data change on the counter. Obvious evidence of the unauthorized use of the key can be naturally left. Therefore, the use of the master key can be effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of auxiliary supplies for power supply safety, and in particular relates to an intelligent master key for electric industry. Background technique [0002] In the switching operation of power system substation equipment outage and power transmission, in order to avoid large-scale power outage accidents due to human factors, a complete set of operating procedures is required. Sequentially designed a set of locking procedures, technically guaranteeing that the next step cannot be performed when the previous step is not completed. However, due to the aging and rusting of the locking equipment during operation, problems such as being stuck and unable to be opened or the sequential key cannot be inserted into the locking equipment when opening, the power supply system ensures that the equipment in all areas can be locked under special circumstances. To open, there is generally a set of keys that can open all cont...
