Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a testing device and method for signal conversion of a data acquisition instrument. Background Technology

[0002] Data acquisition instruments are essential hardware products in the field of environmental monitoring, playing a crucial role. Currently, most emission-emitting enterprises use older 2G data acquisition instruments. Since most surrounding wireless networks have been upgraded from 2G to 4G, the 2G network is unstable, with slow transmission speeds and high packet loss rates, severely impacting the uploading of environmental data. Therefore, modern data acquisition instruments now feature 2G to 4G signal conversion, eliminating the need for users to purchase expensive integrated 4G data acquisition instruments, significantly reducing production and maintenance costs. However, there is a lack of testing devices for the uploaded environmental data.

[0003] In existing technologies, the success rate and stability of data transmission after signal conversion by data acquisition instruments are mostly determined manually. This method is inefficient and limited by the operating environment and time, resulting in low accuracy or errors in the test results. Furthermore, it makes it difficult to quickly determine the cause of data acquisition instrument malfunctions, leading to significant losses. Therefore, providing a testing device and method for signal conversion in data acquisition instruments is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a testing device and method for signal conversion of data acquisition instruments. This invention determines the test level by acquiring the upload transmission rate and upload efficiency of a preset data acquisition device, and determines whether a fault has occurred. When a fault occurs, the cause of the fault is determined and an alarm signal is sent. This solves the problems that the success rate and stability of data transmission after signal conversion by data acquisition instruments are mostly determined manually, resulting in low testing efficiency and low testing accuracy, and the inability to quickly determine the cause of faults when data acquisition instruments malfunction, leading to serious losses.

[0005] To achieve the above objectives, the present invention provides a testing apparatus and method for signal conversion in a data acquisition instrument, the testing apparatus comprising:

[0064] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0065] like Figure 1 As shown, an embodiment of the present invention discloses a testing device for signal conversion of a data acquisition instrument, the testing device 7 comprising:

[0066] The receiving module 101 is connected to the preset data acquisition device, and the receiving module is used to receive data transmitted by the preset data acquisition device;

[0067] Test module 102 is used to test the data transmitted by the preset data acquisition device to obtain the upload transmission rate and upload speed of the data;

[0068] The control module 103 is used to determine the test level of the preset data acquisition device based on the upload transmission rate and upload speed.

[0069] In some embodiments of this application, such as Figure 3 As shown, the preset data acquisition device includes:

[0070] The 2G data acquisition instrument 1 is connected to the environmental analyzer 8. The 2G data acquisition instrument 1 is used to receive, store and transmit the data collected by the environmental analyzer 8 through the RS232 / RS485 interface.

[0071] The signal conversion mechanism includes a 4G router 2 and a 4G network enhancer 4. The 4G router 2 is used to convert the 2G signal of the 2G data acquisition device 1 into a 4G signal, and the 4G network enhancer 4 is used to strengthen the 4G signal strength.

[0072] Power supply 5 is used to provide uninterrupted power to the signal conversion mechanism.

[0073] In this embodiment, the 2G data acquisition device 1 is connected to the environmental analysis instrument 8 at one end and to the 4G router 2 at the other end. The signal of the 2G data acquisition device 1 is transmitted to the 2G network through the 2G network antenna 6. The conversion mechanism also includes a 4G network antenna 3. The 4G router 2 and the 4G network enhancer 4 are connected through the 4G network antenna 3 to convert the 2G network to a 4G network. The preset data acquisition device is the 2G data acquisition device 1. Since most of the surrounding wireless networks have been upgraded from 2G to 4G, the 2G network is unstable, and the transmission rate is slow with a high packet loss rate, which seriously affects the uploading of environmental data. The 2G signal of the 2G data acquisition device 1 is converted to a 4G signal, and the test device 7 is used to test whether the data transmission is stable after the signal conversion of the preset data acquisition device.

[0074] In some embodiments of this application, the control module 103 acquires the upload transmission rate A0 and presets a first preset upload transmission rate V1, a second preset upload transmission rate V2, a third preset upload transmission rate V3, and a fourth preset upload transmission rate V4, wherein V1 < V2 < V3 < V4; and presets a first preset test level T1, a second preset test level T2, a third preset test level T3, a fourth preset test level T4, and a fifth preset test level T5, wherein T1 < T2 < T3 < T4 < T5;

[0075] When A0 < V1, the first preset test level T1 is selected as the current test level;

[0076] When V1≤A0<V2, the second preset test level T2 is selected as the current test level;

[0077] When V2≤A0<V3, the third preset test level T3 is selected as the current test level;

[0078] When V3≤A0<V4, the fourth preset test level T4 is selected as the current test level;

[0079] When V4≤A0, the fifth preset test level T5 is selected as the current test level.

[0080] In this embodiment, the test level of the preset data acquisition device after signal conversion is determined based on the upload transmission rate, which is the stability of data transmission. The higher the test level, the higher the stability of the preset data acquisition device after signal conversion.

[0081] In some embodiments of this application, the control module 103 acquires the upload rate H0 and presets a first preset upload rate L1, a second preset upload rate L2, and a third preset upload rate L3, wherein L1 < L2 < L3.

[0082] When L1≤H0<L2, the i-th preset test level Ti is reduced by one level, and the current test level is T(i-1). If i=1, the current test level is directly determined to be the first preset test level T1.

[0083] When L2≤H0<L3, the i-th preset test level Ti is increased by one level, and the current test level is T(i+1). If i=5, the current test level is directly determined to be the fifth preset test level T5.

[0084] When L3≤H0, the i-th preset test level Ti is increased by two levels, and the current test level is T(i+2). If i=5, the current test level is directly determined to be the fifth preset test level T5.

[0085] In this embodiment, the test level can be adjusted according to different upload speeds based on historical test data. When the upload speed is low, the corresponding test level is reduced by one level. If the test level is already the first preset test level, the current test level is directly determined as the first preset test level. When the upload speed is medium, the corresponding test level is increased by one level. If the test level is already the fifth preset test level, the current test level is directly determined as the fifth preset test level. When the upload speed is high, the corresponding test level is increased by two levels. If the test level is already the fifth preset test level, the current test level is directly determined as the fifth preset test level.

[0086] In some embodiments of this application, the control module 103 is further configured to determine whether the preset data acquisition device has malfunctioned based on the test level; if a malfunction occurs, the cause of the malfunction is obtained and an alarm signal is sent.

[0087] When the test level of the signal conversion of the preset data acquisition device is the first preset test level, it is determined that the preset data acquisition device has malfunctioned.

[0088] The control module 103 is pre-set with a preset fault transmission rate interval (g, f), where 0 < g < f < V1, and is pre-set with a first preset fault cause and a second preset fault cause. The fault cause is determined based on the relationship between the upload transmission rate A0 and the preset fault transmission rate interval (g, f).

[0089] When g≤A0≤f, the cause of the fault is determined to be the first preset fault cause;

[0090] When 0 ≤ A0 < g, the cause of the fault is determined to be the second preset fault cause.

[0091] When the upload transmission rate is within the preset fault transmission rate range, it is determined that the transmission module of the preset data acquisition device has malfunctioned.

[0092] In this embodiment, the most common causes of failure in the preset data acquisition device are data acquisition failure and data transmission failure. Data acquisition failure is caused by interrupted or invalid data transmission, which affects the data upload rate. The preset failure transmission rate can be obtained based on historical data. When the upload transmission rate is within the preset failure transmission rate, the cause of failure can be determined to be data acquisition failure. When the data on the preset data acquisition device is normal, but there is no data in the test device 7, the cause of failure can be determined to be data transmission failure, that is, the upload transmission rate is close to 0. Among them, the first preset failure cause is data acquisition failure, and the second preset failure cause is data transmission failure. The cause of failure can be determined and an alarm signal can be sent based on the upload transmission rate and the test level.

[0105] When V2≤A0<V3, the third preset test level T3 is selected as the current test level;

[0106] When V3≤A0<V4, the fourth preset test level T4 is selected as the current test level;

[0107] When V4≤A0, the fifth preset test level T5 is selected as the current test level.

[0108] In some embodiments of this application, the upload rate H0 is obtained, and a first preset upload rate L1, a second preset upload rate L2, and a third preset upload rate L3 are preset, where L1 < L2 < L3.

[0109] When L1≤H0<L2, the i-th preset test level Ti is reduced by one level, and the current test level is T(i-1). If i=1, the current test level is directly determined to be the first preset test level T1.

[0110] When L2≤H0<L3, the i-th preset test level Ti is increased by one level, and the current test level is T(i+1). If i=5, the current test level is directly determined to be the fifth preset test level T5.

[0111] When L3≤H0, the i-th preset test level Ti is increased by two levels, and the current test level is T(i+2). If i=5, the current test level is directly determined to be the fifth preset test level T5.

[0112] In some embodiments of this application, it is determined whether the preset data acquisition device has malfunctioned based on the test level; if a malfunction occurs, the cause of the malfunction is obtained and an alarm signal is sent.

[0113] When the test level of the signal conversion of the preset data acquisition device is the first preset test level, it is determined that the preset data acquisition device has malfunctioned.
