Technical Field

[0001] The present invention relates to the field of vehicle testing technology, and more particularly to a multi-test system joint adjustment emergency stop control system and a control method thereof. Background Art

[0002] At present, there is a separate emergency stop control device for a single test system. In case of an emergency, press the emergency stop button and the test system will stop supplying power. With the development of testing requirements, it is necessary to complete the separate testing of all controllers before the controllers are installed on the actual vehicle, as well as the testing of multiple controllers connected according to the actual vehicle network layout. In response to this testing requirement for the controller, the test system needs to support both the separate testing of a single controller and the joint testing of multiple controllers. Accordingly, the emergency stop control of the test system needs to support both the separate control of a single test system for emergency power off and the use of multiple test systems for joint testing. Pressing the emergency stop button of any test system can realize the emergency power off of multiple systems at the same time. The emergency stop control of the two scenarios can be switched without affecting each other. Summary of the invention

[0003] The purpose of the present invention is to design and develop a multi-test system joint emergency stop control system, which not only ensures the independence of each test system but also enables the series connection of multiple test systems, thereby improving safety and intelligence.

[0004] The present invention also designs and develops a control method for a multi-test system joint emergency stop control system, which realizes emergency stop control of a single test system and multiple test systems through signal detection at different positions of different loops.

Multiple test systems all work normally, and multiple power switches all remain in a normally closed state.

[0019] When any test system is tested, the corresponding detection switch is connected to the corresponding second signal receiving end. If the corresponding second signal sending end is turned on and sends a constant voltage or PWM signal, the corresponding constant voltage or PWM signal is detected at the second signal receiving end, the test system works normally, and the power switch corresponding to the test system remains in a normally closed state;

[0020] Step 3: When testing multiple test systems simultaneously, if any one of the first control switches is turned on, the first signal receiving end of the main test system cannot detect the constant voltage or PWM signal, the first signal sending end of the main test system stops sending the constant voltage or PWM signal, the first signal receiving ends of the multiple groups of test modules cannot detect the constant voltage or PWM signal, and the multiple groups of detection loop modules turn off the corresponding multiple power switches;

[0031] The present invention is further described in detail below so that those skilled in the art can implement it according to the description.

[0032] like Figure 1 As shown, a multi-test system joint debugging emergency stop control system provided by the present invention includes multiple power switches and multiple groups of test modules. The multiple test systems are all connected to an external power supply circuit for powering on the multiple test systems; the multiple power switches are respectively and one-to-one arranged between the external power supply circuit and the multiple test systems; the multiple groups of test modules are respectively arranged corresponding to the multiple test systems, and each group of test modules corresponds to a test system, for respectively and one-to-one controlling the opening or closing of the multiple power switches.

[0033] The test module includes a detection circuit module and an emergency stop control module, specifically:

[0034] The detection loop module includes a first signal emitting terminal a, a first signal receiving terminal b, a second signal emitting terminal aˊ and a second signal receiving terminal bˊ. The emergency stop control module includes a first control switch S1 and a second control switch S2. The first signal emitting terminal a can be selectively connected or disconnected with the first signal receiving terminal b. One end of the first control switch S1 is connected to the first signal receiving terminal b, and the other end is connected to the first signal emitting terminal a of other test modules, so that the first signal emitting terminal a, the first signal receiving terminal b and the first control switch S1 in multiple groups of test modules are connected in sequence and then connected end to end to form a series loop 1; one end of the second control switch S2 is connected to the second signal emitting terminal aˊ, and the other end is connected to the second signal receiving terminal bˊ, so that the second signal emitting terminal aˊ and the second signal receiving terminal bˊ form a loop 2 through the second control switch S2.

[0035] A detection switch S3 is provided at the first signal receiving end b and the second signal receiving end b', and the detection switch S3 can selectively output a signal at the first signal receiving end b or the second signal receiving end b'.

[0036] In this embodiment, the external power supply circuit is 220V / 380V mains electricity.

[0037] In this embodiment, the multiple detection switches S3 are all single-pole double-throw switches, and when the detection switch S3 is in the middle position, the detection switch S3 is neither connected to the first signal receiving terminal b nor to the second signal receiving terminal bˊ, that is, the detection switch S3 does not output a signal at this time; when the detection switch S3 is in the left position, the detection switch S3 is connected to the first signal receiving terminal b, and the first signal receiving terminal b in the loop 1 can be used for signal or voltage detection; when the detection switch S3 is in the right position, the detection switch S3 is connected to the second signal receiving terminal bˊ, and the second signal receiving terminal bˊ in the loop 2 can be used for signal or voltage detection, and when the detection switch S3 is turned on, the signal can be collected through other detection modules.

[0038] The invention designs and develops a multi-test system joint adjustment emergency stop control system, which not only ensures the independence of each test system, but also can realize the series connection of multiple test systems, thereby improving safety.

[0039] The present invention also provides a control method for a multi-test system joint debugging emergency stop control system, which specifically comprises the following steps:

[0040] Step 1: Connect multiple groups of test modules to multiple test systems one by one;

[0041] The multiple test systems are divided into a main test system and multiple auxiliary test systems, and the first signal sending end a and the first signal receiving end b in the main test system are kept disconnected. Figure 2 As shown, the first signal emitting terminal a and the first signal receiving terminal b in the multiple sub-test systems are kept in a connected state, so that the first signal emitting terminal a, the first signal receiving terminal b and the first control switch S1 in the multiple groups of test modules are connected in sequence and then connected end to end to form a series loop 1; the second signal emitting terminal aˊ and the second signal receiving terminal bˊ in each group of test modules are formed into a loop 2 through the second control switch S2, and the first control switch S1 and the second control switch S2 in the multiple sub-test systems are both in a normally closed state. At this time, loop 1 is used to connect multiple test systems in series, and loop 2 is only used for this test system. At the same time, the detection loop module can The power switch is used to control the emergency power off of 220V / 380V power supply, and the emergency stop control module is used to control the disconnection of loop 1 and / or loop 2. The first signal sending terminal a and the second signal sending terminal aˊ of loop 1 and loop 2 of the test module in the main test system both have the function of sending signals. The test modules in multiple sub-test systems only have the function of sending signals from the second signal sending terminal aˊ of loop 2. All test modules have the function of detecting signals from the first signal receiving terminal b and the second signal receiving terminal bˊ of loop 1 and loop 2, and which signal receiving terminal the substrate uses for signal detection is determined by the detection switch S3.

[0042] Step 2: When testing multiple test systems simultaneously, multiple detection switches S3 are connected to the first signal receiving end b one by one, that is, loop 1 is selected to detect the signal, and loop 1 is a series loop. If the first signal sending end a of the main test system is turned on and sends a constant voltage or PWM signal, the corresponding constant voltage or PWM signal can be detected at the first signal receiving end b of each test system, and multiple test systems are working normally, and multiple power switches are kept in a normally closed state.

[0043] When multiple test systems are tested simultaneously, multiple detection switches are connected to the first signal receiving end b one by one. If the first signal sending end a of the main test system is turned on and sends a constant voltage or PWM signal, and the first signal receiving end b of any one or more test systems cannot detect the constant voltage or PWM signal, then the first signal sending end a of the main test system stops sending the constant voltage or PWM signal, and the first signal receiving ends b of the multiple groups of test modules cannot detect the constant voltage or PWM signal, and the multiple groups of detection loop modules shut down the corresponding multiple test systems;

[0044] When testing a single test system, the detection switch S3 corresponding to the test system is connected to the corresponding second signal receiving terminal bˊ, that is, loop 2 is selected to detect the signal. If the corresponding second signal sending terminal aˊ is ​​turned on and sends a constant voltage or PWM signal, the corresponding constant voltage or PWM signal is detected at the second signal receiving terminal bˊ, the test system works normally, and the power switch corresponding to the test system remains in a normally closed state;

[0045] Step three, when testing multiple test systems at the same time, if any one of the first control switches S1 is turned on, at least the first signal receiving end b of the main test system cannot detect the constant voltage or PWM signal. At this time, the first signal sending end a of the main test system stops sending the constant voltage or PWM signal, and the first signal receiving ends b of multiple groups of test modules cannot detect the constant voltage or PWM signal. Multiple groups of detection loop modules turn off the corresponding multiple power switches, that is, multiple test systems are disconnected from the 220V / 380V power supply, so that all test systems are disconnected from the 220V / 380V power supply;

[0046] When testing a single test system, if the second control switch S2 corresponding to the test system is pressed (on state), only the second signal receiving end bˊ corresponding to the test system cannot detect the constant voltage or PWM signal emitted by the second signal sending end aˊ, and the detection loop module corresponding to the test system controls the corresponding power switch to turn off, that is, the 220V / 380V of this test system is urgently powered off, and the power switches corresponding to the other test systems all remain in the normally closed state, which does not affect the signal detection and 220V / 380V power supply of the second signal receiving end bˊ of loop 2 of other test systems.

[0047] In this embodiment, the constant voltage value is 5V.

[0048] like Figure 3 As shown, in the present embodiment, three test systems are controlled by a joint emergency stop control system, with test system 1 being the main test system, and test systems 2 and 3 being auxiliary test systems. After being connected according to the control method of the present invention, loop 1 is a series loop, and loop 2 is a single detection loop for each test system. Once multiple test systems need to be emergency stopped at the same time, it is only necessary to press the first control switch S1 in any emergency stop control module to achieve simultaneous power off of the three test systems. If only a single test system needs to be emergency stopped, press the second control switch S2 in the corresponding emergency stop control module to achieve power off of the single test system, but it does not involve the power supply of other test systems.

[0049] A control method for a multi-test system joint emergency stop control system designed and developed by the present invention not only realizes the individual emergency stop control of each test system, but also realizes the simultaneous emergency stop control of multiple test systems, thereby improving the detection efficiency and the detection safety.

They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
