The application provides a test method for an analog signal communication system; the application also provides a testing device for the analog signal communication system. Details are described in the following examples one by one.
The present application provides a first embodiment, namely an embodiment of a test apparatus for an analog signal communication system.
The present embodiment is described in detail below with reference to fig. 1, where fig. 1 is a block diagram of a testing apparatus for an analog signal communication system according to an embodiment of the present application.
Referring to fig. 1, the present application provides a testing apparatus for an analog signal communication system, including: the system comprises a wireless communication module 101, a control module 102 and a test module 103;
the wireless communication module 101 is configured to receive request information for testing the first analog channel transmitted in a wireless communication manner.
Wireless communication is a communication method for exchanging information by using the characteristic that an electromagnetic wave signal can propagate in a free space. The most common wireless communication methods include: communication methods conforming to mobile communication protocols, such as 2G, 3G, 4G, 5G, etc. in mobile communication. Meanwhile, the wireless communication mode also comprises satellite communication.
A channel, which refers to a channel for communication, is a medium for signal transmission.
Analog channels, which refer to channels capable of carrying analog signals, are referred to as analog channels. The level of the analog signal varies continuously with time, and the speech signal is a typical analog signal.
The purpose of this embodiment is to automatically establish a test environment for an analog channel at a dispatch master station through a device for remotely controlling a substation.
The receiving of the request information for testing the first analog channel transmitted in the wireless communication mode is to receive the information for requesting the test of the first analog channel sent by the dispatching master station by using the wireless communication module 101 of the substation. For example, a Data Transfer Unit (DTU) device is used for wireless communication modules of the scheduling master station and the substation, the DTU device is a wireless terminal device that is specially used for converting serial Data into IP Data or converting IP Data into serial Data and transmitting the serial Data through a wireless communication network, a computer of the scheduling master station, on which the DTU device is installed, sends request information for testing a first analog channel to a specified substation through the DTU device, and the device of the embodiment in the substation receives the request information through the DTU device connected thereto.
The control module 102 is electrically connected to the wireless communication module 101, and configured to establish an electrical connection between the first analog channel and the test module 103 according to the request information; the test module 103 is configured to respond to test information transmitted by the electrically connected analog channel.
When the first analog channel is electrically connected to the test module 103, an independent test environment for testing the first analog channel is generated. The test module 103 receives the test information of the scheduling master station, analyzes the test information, completes the test according to the convention in the test information, and returns the test result to the scheduling master station. And the scheduling master station evaluates the test result and generates a test conclusion.
The control module 102 is electrically connected to the wireless communication module 101, that is, the wireless communication module 101 sends the received wireless communication information to the control module 102 for analysis and processing, and the control module 102 returns the information required by the scheduling master station to the scheduling master station through the wireless communication module 101. For example, the control module is a single chip microcomputer installed in a transformer substation, and the single chip microcomputer is connected with the DTU through a USB port.
The control module 102 includes: a judging unit and a connecting unit.
And the judging unit is used for judging whether the first analog channel is in the data information transmission process after the request information is obtained.
The purpose of the judging unit is to prevent the first analog channel from receiving the request message for testing the first analog channel during the data transmission period, which results in the interruption of data transmission.
The data information transmission process at least comprises one of the following transmission processes:
in the first transmission process, the amplitude of the data information continuously changes during the transmission process. In this case, it indicates that data is being transmitted continuously.
In the second transmission process, the amplitude of the data information changes discontinuously within a preset time interval range. For example, the amplitude of two different pieces of data varies discontinuously during transmission, but the time interval of transmission is within a preset time interval, and the two pieces of data are defined as the same transmission process. For example, the preset time interval is 1 second.
And a third transmission process, wherein the data information transmission process completes the preset data information transmission scheme. For example, the preset data information transmission scheme includes a series of data information including control information for causing the substation to perform a specific set of actions, wherein the amplitude of the data information includes continuous variation and/or discontinuous variation. For example, the scheduling master station transmits a series of control messages, wherein the amplitude of each control message is continuously varied, a time interval exists between each control message, and the amplitude between two adjacent control messages is non-continuously varied.
All three transmissions are defined as not suitable for terminal transmission during transmission, and enter the testing stage. The operation of the connection unit can be performed only outside the above three transmission procedures.
And the connection unit is used for establishing the electrical connection between the first analog channel and the test module 103 when the output result of the judgment unit is negative.
The control module 102 further includes: and a disconnection unit.
The operation of the disconnection unit is performed while the operation of the connection unit is performed.
The disconnection unit is used for electrically disconnecting the first analog channel from the working module; the working module responds to the working information of the control substation equipment transmitted by the electrically connected analog channel. For example, the working module is a computer for controlling the telemechanical of the transformer substation to work, when a test environment for a first simulation channel is built, a disconnection unit of the control module in the single chip microcomputer disconnects the first simulation channel from the computer, so that the test environment becomes an independent closed environment, and normal operation of the transformer substation is influenced by testing.
Furthermore, the normal operation of the master station and the substation is not affected by the test. The disconnection unit further includes:
a second analog channel subunit is connected and used for connecting a second analog channel in the analog signal communication system and electrically connecting the second analog channel with the working module; the second analog channel functions in the same way as the first analog channel. For example, the second analog channel is a spare analog channel of the first analog channel, and when the first analog channel builds a test environment, the second analog channel takes over the responsibility of the first analog channel to transmit analog information between the scheduling master station and the substation.
The wireless communication module further comprises: and the system is used for transmitting return information of the permission test to the request end in a wireless communication mode.
In the embodiment, the test information is sent through wireless communication, so that the influence of information transmission through a simulation channel on normal work is avoided, and the time, the fund and the occupied space consumed by laying a special wired channel are reduced; by using the method in the transformer substation, the communication channel test becomes simple, workers do not need to go to each transformer substation for field test, and the labor cost and the time cost are reduced; and a double-channel working mode is adopted, so that the influence on the work during single-channel testing is avoided.
