DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and should not be construed as limiting the present invention.

[0045] It should be noted that although the functional modules are divided in the schematic diagram, in some cases, the module division can be different from that in the system.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0047] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0048] Before industrial product equipment is put into operation or during the production process, the modules of the equipment need to be functionally tested and verified to prevent problems during subsequent assembly that make module replacement difficult. However, there may be multiple solenoid valves, position control valves or sensors in the module. During testing and verification, they need to be controlled at the same time to keep them open or closed, or to show a certain state. For example, for a pressure test, it is necessary to continuously open the solenoid valves on all pipelines in the module, open the proportional valve to one position, or detect whether the signal continuously fed back by the sensor in the module is accurate and stable. In addition, before the industrial product equipment is put into operation, if it fails to connect to the control device, the industrial product equipment will temporarily be unable to use the program to control the above-mentioned valve body and sensor at the same time.

[0049] In the existing technology, commonly used signal generators can only output or receive a single channel for a short period of time, and cannot provide signals for a long time. It is difficult to provide multiple different model sources for testing and verification of industrial products and equipment.

[0050] Reference Figures 1 to 4 In some embodiments of the first aspect of the present invention, the multi-channel signal source integrated generator includes: a power configuration module 100, a power distribution terminal block 200, at least one variable signal generation module 300 and at least one power supply module 400.

[0051] The external input power supply is electrically connected to the input end of the power configuration module 100. The power configuration module 100 receives the external input power supply and is configured to output a first DC power supply and at least one AC power supply.

[0052] Among them, the external input power supply and AC power supply are both 220V AC power supplies.

[0053] The input port of the power distribution terminal block 200 is electrically connected to the output end of the power configuration module 100 . The power distribution terminal block 200 receives the first DC power supply and separately configures it to obtain at least one second DC power supply.

[0054] Specifically, the first DC power supply of the power configuration module 100 is input to the power distribution terminal block 200 as a power supply. The input terminals on the power distribution terminal block 200 are fixedly connected to the first DC power supply, distributing the first DC power supply. Several output terminals lead to several second DC power supplies. Both the first and second DC power supplies are 24V DC power supplies.

[0055] The input end of each variable signal generating module 300 is electrically connected to the output end of the power configuration module 100. The variable signal generating module 300 can receive an AC power source, measure the input detection signal, and output a required supply signal.

[0056] That is, one AC power source of the power configuration module 100 is used as a power supply and is electrically connected to the input terminals of the multiple variable signal generators. Each variable signal generating module 300 is capable of measuring an external input detection signal and outputting a required supply signal.

[0057] The detection signals can be voltage, current, and resistance. The required supply signals can be a voltage signal of 0 to 24V, a DC current signal of 0 to 20mA, and a resistance signal of 0 to 400Ω, with a minimum output resistance signal of 15Ω. Multiple variable signal generation modules 300 are used to simultaneously output different types of supply signals and measure different types of detection signals.

[0058] The input end of each power supply module 400 is electrically connected to the output port of the power distribution terminal block 200 , and the power supply module 400 can supply the second DC power source as power supply to the outside.

[0059] That is, a single power supply module 400 is electrically connected to a single output port in the power distribution terminal to supply the second DC power source led out of the power distribution terminal. Multiple power supply modules 400 are used to achieve simultaneous output of multiple second DC powers.

[0060] Among them, the variable signal generating modules 300 can be set to 4, the power supply modules 400 can be set to 10, and 10 second DC power supplies can be output.

[0061] The first DC power output by the power configuration module 100 is separately configured through the distribution terminal block 200, so that at least one power supply module 400 can simultaneously output multiple second DC power supplies, and the input detection signal can be measured through at least one variable signal generating module 300, and multiple adjustable required supply signals can be output simultaneously. The utility model integrates multiple power supply modules 400 and multiple variable signal generating modules 300 to form a signal source generator with multiple outputs, and the output signal source is stable and adjustable. It adopts a one-to-many signal generation mode and can output multiple signal sources at the same time, meeting the testing requirements of industrial product equipment, reducing related instruments in the testing device, and reducing testing costs.

[0064] The first power adapter 120 can convert the external input power into a first DC power. That is, the first power adapter 120 can convert 220V AC power into 24V DC power.

[0065] The input of backup power circuit 130 is electrically connected to an external input power source, and the output of backup power circuit 130 is electrically connected to an input port of power distribution terminal block 200. Backup power circuit 130 can output one channel of AC power. Backup power circuit 130 can provide backup AC power in the event of an abnormality in the remaining AC power supply.

[0066] The input end of the terminal strip circuit 140 is electrically connected to an external input power source, and the terminal strip circuit 140 is electrically connected to the input port of the power distribution terminal block 200. The terminal strip circuit 140 can output a single AC power source. The terminal strip circuit 140 can supply AC power to the power distribution terminal block 200 for subsequent connection to other generators. The power distribution terminal block 200 can also be used or removed by an on / off switch in the terminal strip circuit 140.

[0067] In the prior art, testing is achieved by temporarily bridging various DC power supplies and other various signals, which results in a large wiring workload, low efficiency, and easy misconnection of lines. In comparison, the present embodiment configures the external input 220V AC power supply through the power configuration module 100, outputs one 24V DC power supply and several 220V AC power supplies, thereby providing multiple and stable DC power supplies, and can provide signals for a long time compared to a handheld signal generator.

[0068] Reference Figures 1 to 4 In some embodiments of the first aspect of the present invention, the variable signal generating module 300 includes: a second power adapter 310, an adjustment button, a multi-signal generator 320, a measurement interface 330, a supply output interface 340 and a common end interface 350.

[0069] The adjustment button is electrically connected to the input end of the multi-signal generator 320 . The adjustment button can respond to an adjustment instruction from a user and send an adjustment signal to the multi-signal generator 320 .

[0070] The multi-signal generator 320 receives the adjustment signal and outputs an adjusted voltage signal, current signal or resistance signal, that is, supplies the desired supply signal required by the user.

[0071] The supply output interface 340 is electrically connected to the output end of the multi-signal generator 320 . The supply output interface 340 is electrically connected to an external device through a wire. The supply output interface 340 can output a required supply signal to the external device.

[0072] In one embodiment, when the adjustment instruction is passive current output and outputting 10mA current, the adjustment button can respond to the adjustment instruction and output the adjustment signal. The multi-signal generator 320 outputs a 10mA passive current signal through the supply output interface 340 according to the adjustment signal.

[0073] In one embodiment, when the adjustment instruction is voltage output and outputting a 15V voltage, the adjustment button can respond to the adjustment instruction and output the adjustment signal. The multi-signal generator 320 outputs a 15V DC voltage signal through the supply output interface 340 according to the adjustment signal.

[0074] In one embodiment, when the adjustment instruction is to output the thermal resistance and output a resistance of 100Ω, the adjustment button can respond to the adjustment instruction and output the adjustment signal. The multi-signal generator 320 outputs a 100Ω thermal resistance signal through the supply output interface 340 according to the adjustment signal.

[0075] The measurement interface 330 is electrically connected to an external device under test via a wire, and is electrically connected to an input terminal of the multi-signal generator 320.

[0076] The multi-signal generator 320 is provided with a display screen. The multi-signal generator 320 measures the detection signal and displays the value of the detection signal through the display screen.

[0077] For example, when the input detection signal is a current of 10 mA, the multi-signal generator 320 can measure a passive current signal of 10 mA through the measurement interface 330. When the input detection signal is a voltage of 15 V, the multi-signal generator 320 can measure a voltage signal of 15 V through the measurement interface 330.

[0078] The input of the second power adapter 310 is electrically connected to the output of the power configuration module 100, which is in turn electrically connected to the input of the multi-signal generator 320. The power configuration module 100 receives an AC power input, and the second power adapter 310 converts the input AC power to generate a third DC power supply. The third DC power supply is then output as a power supply to the multi-signal generator 320.

[0079] The detection signals can be voltage, current, and resistance. The required supply signals can be a voltage signal of 0 to 24V, a DC current signal of 0 to 20mA, and a resistance signal of 0 to 400Ω, with a minimum output resistance signal of 15Ω. Multiple variable signal generation modules 300 are used to simultaneously output different types of supply signals and measure different types of detection signals.

[0080] In this embodiment, a plurality of variable signal generating modules 300 cooperate with each other to obtain a multi-channel integrated signal generator, which can continuously and stably output multiple channels of different types of signals while measuring the input signals of external devices, thereby meeting the testing and verification requirements of various industrial products and reducing the use of related instruments.
