Embodiment 1

[0017] Short message and digital transmission remote communication testing device of the present invention, as figure 1 As shown, it includes a first analog Modem, a first communication interface and a first AT command unit corresponding to the first device under test, a second analog Modem, a second communication interface and a second AT command corresponding to the second device under test units, and data interaction modules.

[0018] The first device under test, the first communication interface, the first analog Modem, the data interaction module, the second analog Modem, the second communication interface and the second device under test are connected in sequence, and the first AT command unit and the second AT command unit are respectively Connect with the first analog Modem and the second analog Modem.

[0019] The functions of the simulated Modem and the real Modem are the same, that is, by querying the AT command in the AT command unit, the received SMS and data tra...

Embodiment 2

[0022] Since the communication interface on the computer is generally an RS232 interface, the two communication interfaces in Embodiment 1 are realized by the RS232 interface in this embodiment, and can also be general communication interfaces such as network port or USB port in addition. The first device to be tested is connected to the first communication interface, and the joint connected to the first communication interface is a DB9 interface. The TX of the DB9 interface is connected to the RX of the first communication interface, and the RX of the DB9 is connected to the TX of the first communication interface. The second device to be tested is connected to the second communication interface, and the connection at the second communication interface end is a DB9 interface, the TX of the DB9 interface is connected to the RX of the second communication interface, and the RX of the DB9 is connected to the TX of the second communication interface.

Embodiment 3

[0025] The difference between this embodiment and Embodiment 2 is that the remote communication test device of this embodiment also includes a configuration module, such as figure 2 As shown, the configuration module is used to configure the parameters of the first analog Modem, the second analog Modem, the first communication interface and the second communication interface, and also configure the AT commands in the first AT command unit and the second AT command unit to adapt to the first AT command unit A device under test and a second device under test. The closer the simulation Modem is to the real Modem, the closer the remote communication test results using the simulation Modem are to the results obtained through the real Modem. The parameters of the first simulation Modem and the second simulation Modem include Modem name, Modem model and telephone number, and the parameters of the first communication interface and the second communication interface include the port n...

Abstract

The invention discloses a testing device for remote communications of short messages and data transmission. The testing device comprises a first analog modem, a first communication interface and a first attention (AT) instruction unit which correspond to a first device to be tested; and a second analog modem, a second communication interface and a second AT instruction unit which corresponding to a second device to be tested. The first analog modem and the second analog modem have the same function as a real global system for mobile communications (GSM) modem, are arranged in the same computer, and communicate with each other through a data interactive module instead of the real GSM modem for developing, debugging and testing, and therefore neither the constraint of the network quality is imposed, nor the communication cost is generated.

Description

technical field [0001] The invention relates to the field of remote communication technology, in particular to a short message and data transmission remote communication test device. Background technique [0002] At present, many remote monitoring devices and monitored devices are equipped with GSM Modem for remote communication and monitoring management. Before the remote monitoring equipment and the monitored equipment are put into use, it is necessary to carry out the remote communication test of SMS and data transmission. The remote communication test needs to send and receive short messages and data transmission data through the GSM Modem. Since the GSM Modem communicates through the network, the remote communication test will generate communication costs, and the cost is not low. At the same time, limited by the signal quality and network speed, it is impossible to test the stress and performance of a large number of SMS or data transmission data. Contents of the in...
