Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing:

[0010] Such as figure 1 Shown: the number of poles of the plug in this embodiment is 4 poles; the precision resistance in the characteristic resistance circuit is 4.

[0011] The plug J1 of this embodiment adopts a 3.5mm universal 4-pole earphone plug with a model of XXHD / p20, 1 pole and 2 poles are serial port terminals, 1 pole is sending Tx, 2 poles are receiving Rx, 3 poles are connected to the positive pole of the DC power supply, and 4 poles Connect the negative pole of the DC power supply, and connect the characteristic resistance circuit in parallel between the 3 poles and 4 poles.

[0012] The Bluetooth serial communication module IC1 adopts the Bluetooth serial communication module of model HC 05, which is powered by 3.3V, where Tx (terminal 1) is connected to the 1st pole of the plug, Rx (terminal 2) is connected to the 2nd pole of the plug, and Vcc (terminal 12)...

Abstract

The invention relates to a plug-type Bluetooth serial-port electronic key. The plug-type Bluetooth serial-port electronic key is composed of a plug, a characteristic resistance circuit and a Bluetooth serial-port communication module, and is characterized in that two poles of the plug are connected to a serial-port sending end pin of the Bluetooth serial-port communication module and a serial-port receiving end pin of the Bluetooth serial-port communication module respectively, and the two other poles of the plug are connected with the characteristic resistance circuit in parallel, connected to an external power source and then connected with a power source leading end pin of the Bluetooth serial-port communication module and a grounding end pin of the Bluetooth serial-port communication module respectively. According to the plug-type Bluetooth serial-port electronic key, as the plug-type structure with the Bluetooth serial-port communication module is adopted, the plug-type Bluetooth serial-port electronic key has the advantages of being small in volume, light in weight and convenient to carry, wireless communication between the plug-type Bluetooth serial-port electronic key and an intelligent mobile phone can be also achieved, and therefore controlling of five-prevention APP software in the intelligent mobile phone is used to avoid incorrect operation of a site.

Description

technical field [0001] The invention relates to a locking device for preventing misoperation of electrical equipment, in particular to a plug-type bluetooth serial port electronic key. Background technique [0002] In substation operation mode switching or maintenance operations, it is often necessary to continuously operate multiple switches and switches and other primary equipment. In order to ensure correctness and prevent misuse, substations are equipped with five-prevention systems. Operation and maintenance personnel must first operate on the simulation panel or The simulation operation is carried out on the five-proof computer, and then the device number is transmitted to the five-proof key according to the operation sequence by the simulation disk or the five-proof machine. During formal operation, the operation and maintenance personnel insert the five-proof key into the five-proof socket on the operation screen of the primary equipment, and a pair of normally open ...
