Description

Technical Field

[0001] The present invention relates to the technical field of CPE design, and in particular to a CPE testing method and system based on a circuit testing board. Background Art

[0002] With rising living standards, the demand for CPEs continues to grow, and the number of CPEs produced has also increased. This has necessitated a simpler, more portable, and less expensive method for performing CPE ringing aging tests. Current CPE ringing aging testing methods rely on either connecting to a wired telephone, which requires a wired telephone for each CPE device under test. Alternatively, they rely on voice cards, which are costly and require specialized voice card hardware and software. With both methods, the more devices tested simultaneously, the more wired phones or voice cards required, increasing the cost. Conversely, with fewer devices tested simultaneously, the test efficiency decreases, making them inefficient and unable to meet the testing needs of high-volume factory production. Summary of the Invention

[0003] The invention discloses a CPE testing method and system based on a circuit testing board, which reduces the cost of CPE testing and improves the efficiency of CPE testing.

[0004] To achieve the above objectives, in a first aspect, the present invention provides a CPE testing method based on a circuit testing board, comprising:

[0005] By changing the current switch on the circuit test board, a current and a voltage are formed between the circuit test board and the CPE, thereby obtaining the current value and the voltage value between the circuit test board and the CPE;

[0006] According to the current and a preset CPE ringing test program, the ringing time of the CPE is obtained by using an electrical signal simulation device preset on the circuit test board;

[0007] The test result of the CPE is obtained by comparing the current value, the voltage value and the ringing time with preset test thresholds respectively.

The circuit test board has no restrictions on the type of CPE and can adapt to the type of CPE, reducing testing costs. The CPE is then continuously ringed based on the current and a preset ringing program, so that the circuit test board receives the ringing current generated by the CPE ringing and displays the current according to a preset electrical signal simulation device on the circuit test board. The ringing time of the CPE is then obtained, and the CPE test results are obtained based on the current, voltage, and ringing time. Using this test board, the present invention can complete CPE ringing aging and off-hook detection tests in conjunction with a simple CPE ringing program without using a telephone, reducing testing costs. Furthermore, different tests can be completed by changing the circuit switches on the test board, improving testing efficiency.

[0022] If the off-hook voltage value is not within the off-hook voltage threshold range or the off-hook current value is not within the off-hook current threshold range, the off-hook detection test result of the CPE is unqualified.

[0023] The present invention can judge whether the current off-hook mode is normal by comparing the current and voltage when the off-hook circuit is formed with a preset threshold value, thereby improving the test efficiency.

[0073] Example 2

[0074] This embodiment provides another CPE testing method based on a circuit testing board. Figure 3 , which mainly includes steps 301 to 303. In this embodiment, each step specifically includes:

[0075] Step 301: Connect a circuit testing board and a CPE, and change a circuit switch on the circuit testing board to form a current and a voltage between the CPE and the circuit testing board.

[0076] In this embodiment, this step mainly includes: connecting the CPE and the RJ11 interface of the circuit test board through a preset telephone line, and connecting the TIP and RING of the telephone line to the DC or AC circuit of the circuit test board; by changing the circuit switch of the circuit test board, a voltage is formed on the TIP and RING at both ends of the RJ11 interface, and a current is generated according to the voltage.

[0077] In this embodiment, the steps are as follows: both the CPE and the voice test board include RJ11 interfaces, which are connected via a common AB telephone line to simulate the CPE being connected to a telephone. Therefore, the CPE short-circuits a variable load circuit between the TIP and RING terminals via the telephone line, and then connects to the corresponding load circuit via the switch on the test board.

[0078] Step 302: Activate the off-hook DC circuit switch or the on-hook DC circuit switch on the circuit testing board to obtain the current value and voltage value between the circuit testing board and the CPE.

[0079] In this embodiment, this step specifically includes: starting the off-hook DC circuit switch to generate an off-hook voltage at both ends of the TIP and RING, and forming an off-hook current based on the off-hook voltage; starting the on-hook DC circuit switch to generate an on-hook voltage at both ends of the TIP and RING, and forming an on-hook current based on the on-hook voltage.

[0080] In this embodiment, the steps are as follows: starting the off-hook DC circuit switch, the CPE directly enters the off-hook state, and when the voice port of the device is connected normally and working, it will remain in the off-hook state, and an off-hook voltage and current will be generated at both ends of TIP and RING; starting the on-hook DC circuit switch, the CPE directly enters the on-hook state, and TIP and RING generate a DC on-hook voltage and a DC current.

[0081] Step 303: Start a preset ringing program and start the ringing AC circuit switch on the circuit test board to obtain the ringing time of the CPE.

[0082] In this embodiment, this step specifically includes: continuously starting the CPE ringing test program and the ringing AC circuit switch to generate an AC or AC / DC voltage at both ends of the TIP and RING, thereby providing a ringing current for the circuit test board; based on the ringing current, displaying the current through an electrical signal simulation device preset on the circuit test board, and obtaining the display time of the electrical signal simulation device, thereby obtaining the ringing time of the CPE.

[0083] In this embodiment, this step specifically involves: in conjunction with the CPE ringing test procedure, the circuit test board receives the AC or AC / DC ringing current voltage at the TIP and RING terminals, generates a current in the ringing AC circuit to simulate the ringing current of a telephone, and displays this electrical signal in a visible form (the circuit ringing LED flashes during ringing and turns off otherwise). Therefore, in conjunction with the CPE continuous ringing test procedure, the CPE's ringing signal continuously passes through the test board, generating a simulated ringing current that is consumed by the test board to obtain the CPE's ringing duration.

[0084] Step 304: Obtain a test result of the CPE according to the current value, the voltage value, and the ringing time.

[0085] In this embodiment, this step mainly includes: obtaining the off-hook or on-hook voltage value and the off-hook or on-hook current value, and comparing them with the preset off-hook or on-hook voltage threshold and the off-hook or on-hook current threshold, respectively, to obtain the off-hook or on-hook detection test result of the CPE, and according to the obtained ringing time, obtaining the aging test result of the CPE.

[0086] In this embodiment, the specific steps are as follows: when the CPE enters the off-hook state, if the voice port of the device is connected normally and working, it will remain in the off-hook state, and a voltage difference of about 10V off-hook voltage and a current of about 22mA will be generated at both ends of TIP and RING, which can complete the off-hook detection simulation test. When the CPE enters the on-hook state, a DC voltage difference of 47.7V and a DC current of 30μA will be generated between TIP and RING. At the same time, based on the ringing time, the aging time of the CPE is obtained, and then the aging test result of the CPE is obtained.

[0087] In addition, in this embodiment, a circuit test board is also provided. Figure 4It mainly consists of RJ11, toggle switch, off-hook DC circuit, ringing AC circuit and on-hook DC circuit. RJ11 connects the TIP and RING of the telephone line to the DC or AC circuit of the test board. The positive voltage difference between the TIP and RING at both ends of RJ11 generates a driving current to drive the LED light. Among them, the toggle switch determines the closed connection of the circuit. When it is dialed up, the off-hook DC circuit is connected to the closed circuit at both ends of TIP and RING, and the ringing and on-hook circuits are disconnected. At this time, the LEDs DS1, DS2 and DS3 of the off-hook circuit are on, and the CPE enters the off-hook state; on the contrary, when the switch is dialed down, the off-hook circuit is disconnected, and the ringing and on-hook currents are closed and connected. At this time, the LED DS5 of the on-hook circuit is slightly bright, and the CPE enters the on-hook state. In conjunction with the CPE ringing program, the CPE is prompted to ring actively. At this time, the LED DS4 of the ringing circuit flashes for 4S off and 1S repeatedly until the ringing ends. By checking the LED status, you can determine whether the CPE voice port has corresponding power supply, and thus simply determine whether the voice function is enabled or running normally.

[0088] In this embodiment, a simple, low-cost, and highly portable circuit test board is used to implement the CPE ringing aging test and off-hook detection. This solves the problem that the CPE ringing aging test requires a telephone test. The number of simultaneous measurements during the ringing aging test can be increased at a low cost. In addition, the device voice port can be tested in an intuitive manner to determine whether power is being fed to determine whether the device voice function is working properly.

[0089] The specific embodiments described above further illustrate the objectives, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it should be noted that any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of protection of the present invention for those skilled in the art.
