specific Embodiment approach 1

[0022] Such as figure 1 As shown, a substation lightning arrester instrument reader includes a main controller 1, a cache module 2, a communication module 3 and a human-computer interaction module 4, and is characterized in that it also includes a camera module 5 and a camera power supply module 6, and the main controller 1 are respectively electrically connected to the camera module 5, the camera power supply module 6, the cache module 2, the communication module 3 and the human-computer interaction module 4;

[0023] The camera module 5 is used to align the display screen of the arrester, collect the image of the display value of the arrester instrument, and send the image of the display value of the arrester instrument to the main controller 1;

[0024] The camera power supply module 6 is used to provide working power to the camera module 5;

[0025] The main controller 1 is used to receive the image of the display value of the arrester meter sent by the camera module 5, a...

specific Embodiment approach 2

[0029] The difference between the second embodiment and the first embodiment is that the main controller 1 can use an STM32F4 series MCU. Specifically preferably adopt STM32F407 single-chip microcomputer.

specific Embodiment approach 3

[0030] The difference between the third embodiment and the second embodiment is that the camera power supply module 6 includes a voltage regulator chip I7 and a voltage regulator chip II8, such as figure 2 As shown, the voltage regulator chip Ⅰ7 is the TPS79613 voltage regulator chip. The IN pin of the voltage regulator chip Ⅱ8 is electrically connected to the 3.3V power supply and grounded, the OUT pin is electrically connected to the 1.3V power supply output terminal and grounded, and the EN pin is electrically connected to the main control The GPIO pin of device 1, the GND pin and the NR / FB pin are grounded;

[0031] Such as image 3 As shown, the voltage regulator chip Ⅱ8 is the TPS79628 voltage regulator chip. The IN pin of the voltage regulator chip Ⅰ7 is electrically connected to the 3.3V power supply and grounded, the OUT pin is electrically connected to the 2.8V power supply output terminal and grounded, and the EN pin is electrically connected to the main control T...

Abstract

Provided in the invention is an identifying and reading instrument of a lightning arrester instrument of a transformer substation. The invention relates to an instrument data transmission device, particularly to a transmission device for a measuring value, a control signal or other similar signals so that problems that errors are made frequently and the efficiency is low because only manual monitoring is carried out by the lightning arrester instrument can be solved. The identifying and reading instrument is composed of a main controller, a caching module, a communication module, a human-computer interaction module, a camera module and a camera power supply module. The camera power supply module and the camera module are electrically connected; and the main controller is connected with thecamera module, the camera power supply module, the caching module, the communication module and the human-machine interaction module electrically. Therefore, a problem that the lightning arrester instrument can not transmit data remotely because of lack of a data transmission interface is solved and thus the labor intensity of the staff is reduced. Moreover, the identifying and reading correctionrate is close to the 100 percent, so that the reading error caused by manual reading is reduced and thus the work efficiency is improved.

Description

technical field [0001] The invention relates to a device for transmitting instrument data, in particular to a device for transmitting measured values, control signals or similar signals. Background technique [0002] In order to ensure the safe operation of the DER new power grid, it is particularly important to monitor the number of operations and leakage current of the arrester. However, because the arrester instrument does not provide a data transmission interface, the current domestic arrester monitoring is to use manual meter reading records to monitor the leakage current and the number of operations of the arrester. However, this method of manual regular inspection and meter reading is labor-intensive, and it is subject to human factors, which is prone to errors and low in efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a substation lightning arrester instrument reading instrument to solve the problem that the arrest...
