Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present invention provides a device for matching a tested object with a test device, which can solve the technical problems of the prior art that manual identification and matching may result in misjudgment and low efficiency.

[0034] See also Figure 1As shown, an embodiment of the present invention provides a device for matching a tested object with a testing device, including: a signal acquisition unit and a controller.

[0035] The signal acquisition unit is used to connect with the object to be measured and collect the identity feature information of the object to be measured.

[0036] The controller is connected to the signal acquisition unit and is used to connect to the test equipment, and the controller is configured as follows:

[0037] Acquire the identity feature information of the object under test collected by the signal collection unit and a preset identity feature information database;

[0038] Identify the identity of the object under test based on the acquired identity feature information and a preset identity feature information database;

[0039] The test equipment is matched according to the identified identity of the object under test.

[0040] Specifically, the identity characteristic information is switch characteristic information, voltage characteristic information, frequency characteristic information or communication coding characteristic information.

[0041] See also Figure 2 As shown, when the identity feature information is switch feature information, the signal acquisition unit includes: a main switch K0, multiple auxiliary switches (K1-Kn) and multiple switch signal acquisition circuits, multiple auxiliary switches are used to be set on the object to be measured, and each of the signal acquisition circuits includes: a current limiting resistor, a pull-up resistor and an isolation module. Optionally, the isolation module is a photoelectric coupler, which transmits electrical signals using light as a medium and has a good isolation effect on input and output electrical signals.

[0042] When the object to be measured is connected to the matching device, the first end of the main switch K0 is connected to the positive pole of the power supply, the first end of each of the auxiliary switches is connected to the second end of the main switch, the second end of each of the auxiliary switches is connected to the first end of each of the isolation modules, the second end of the isolation module is connected to the first end of a corresponding current limiting resistor, the second end of the current limiting resistor is connected to the negative pole of the power supply, the third end of the isolation module is connected to the first end of a corresponding pull-up resistor and the controller, the second end of the pull-up resistor is connected to the pull-up voltage, and the fourth end of the isolation module is grounded. The closed or open states of the plurality of auxiliary switches on different objects to be measured are different.

[0043] See also Figure 2As shown, taking the first signal acquisition circuit as an example, the first signal acquisition circuit includes: a current limiting resistor R11, a pull-up resistor R12 and an isolation module U1. The first end of the auxiliary switch K1 is connected to the second end of the main switch K0, the second end of the auxiliary switch K1 is connected to the first end of the isolation module U1, the second end of the isolation module U1 is connected to the first end of the current limiting resistor R11, the second end of the current limiting resistor R11 is connected to the negative pole of the power supply, the third end of the isolation module U1 is connected to the first end of the pull-up resistor R12 and the controller, the second end of the pull-up resistor R12 is connected to the pull-up voltage, the fourth end of the isolation module U1 is grounded, and the remaining signal acquisition circuits are also connected in a similar manner.

[0044] The closed or open states of the plurality of auxiliary switches on different measured objects are different, that is, the different closed or open states of the auxiliary switches K1 to Kn in different measured objects correspond to the identity characteristic information of the measured objects one by one. When the controller controls the main switch K0 to close, the different closed or open states of the auxiliary switches K1 to Kn in different measured objects are output to the controller through the corresponding isolation module. For example, assuming that the auxiliary switches are K1 to K8, and the closed or open states of the switches K1 to K8 of the measured object A are open, closed, open, closed, open, closed, open, closed, then the controller can obtain the switch characteristic information of low level, high level, low level, high level, low level, high level, low level, high level, and high level, which can be recorded as (0, 1, 0, 1, 0, 1, 0, 1).

The present invention can guide the measured object to match with the corresponding test equipment, and the whole process is automatically performed, with high recognition accuracy and high matching efficiency.

[0046] As an optional implementation, in an embodiment of the invention, matching the test device according to the identified identity of the object to be tested includes:

[0047] The identified identity of the object under test is sent to the test device, so that the test device runs the application matching the object under test according to the identity of the object under test.

[0048] As an optional implementation, in one embodiment of the invention, the controller is a single chip microcomputer or a DSP. A single chip microcomputer is also called a single chip microcontroller, which has the characteristics of small size, light weight and low price. A DSP has high precision, flexibility, programmability, real-time performance, powerful digital filtering function, and convenient storage and transmission capabilities.

Optionally, the isolation module is a photoelectric coupler, which transmits electrical signals using light as a medium and has a good isolation effect on input and output electrical signals.

[0057] When the object to be measured is connected to the matching device, the first end of the main switch K0 is connected to the positive pole of the power supply, the first end of each of the auxiliary switches is connected to the second end of the main switch, the second end of each of the auxiliary switches is connected to the first end of each of the isolation modules, the second end of the isolation module is connected to the first end of a corresponding current limiting resistor, the second end of the current limiting resistor is connected to the negative pole of the power supply, the third end of the isolation module is connected to the first end of a corresponding pull-up resistor and the controller, the second end of the pull-up resistor is connected to the pull-up voltage, and the fourth end of the isolation module is grounded.

[0059] The closed or open states of the plurality of auxiliary switches on different measured objects are different, that is, the different closed or open states of the auxiliary switches K1 to Kn in different measured objects correspond to the identity characteristic information of the measured objects one by one. When the controller controls the main switch K0 to close, the different closed or open states of the auxiliary switches K1 to Kn in different measured objects are output to the controller through the corresponding isolation module. For example, assuming that the auxiliary switches are K1 to K8, and the closed or open states of the switches K1 to K8 of the measured object A are open, closed, open, closed, open, closed, open, closed, then the controller can obtain the switch characteristic information of low level, high level, low level, high level, low level, high level, low level, high level, and high level, which can be recorded as (0, 1, 0, 1, 0, 1, 0, 1). The switch characteristic information can be marked as (0, 1, 0, 1, 0, 1, 0, 1) in the preset identity information feature information library, which refers to the object under test A. That is, when the controller actually obtains the switch characteristic information (0, 1, 0, 1, 0, 1, 0, 1), the identity of the object under test can be identified, and finally the identified identity of the object under test can be matched with the test equipment.
