[0002] With the development of industrial automation, machine vision systems have become the core driver of industrial automation. Lighting is a key factor affecting machine vision system input. Since there are no universal standards for light source equipment, controllers are used to adjust the light source for each specific application scenario to achieve optimal machine vision system performance.

[0003] To meet current industrial needs, controllers often need to control multiple light source outputs and multiple camera outputs, each of which is controlled by an independent timer. As the number of light source outputs and camera outputs increases, the requirements for the controller's control chip also increase. To precisely control N light source outputs and N camera outputs, the controller processor needs at least 2N independent timers, and each of these 2N timers must support at least one PWM (Pulse Width Modulation) output. However, general-purpose processors generally support 3-5 (less than 2N) independent timers, which is insufficient for meeting the requirement of 2N independent timers. Summary of the Invention

[0014] In combination with the first aspect, in one implementable manner, obtaining one-way light source control output and one-way camera control output based on the count value of the counting register and the working mode of the timer includes: outputting a level by comparing the count value of the counting register with the value of a channel comparison register; turning off the light source output when the first count value of the timer is equal to zero; and turning off the control camera output when the second count value of the timer is equal to zero.

[0015] In combination with the first aspect, in one implementable manner, when the light source is outputting and the working mode of the timer is down counting, outputting a level by comparing the count value of the counting register with the value of the channel comparison register includes:

[0016] When the count value of the counting register is greater than the first value of the channel comparison register, a low level is output;

[0035] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] Machine vision automates factory processes based on acquired image data. Machine vision primarily involves light sources, lenses, and cameras. Lighting is a crucial factor affecting the input of machine vision systems. Since there are no universal standards for light source equipment, controllers adjust the lighting for each specific application scenario to achieve optimal results.

[0038] The main function of a light source controller is to control the brightness and lighting status (e.g., on, off, etc.) of the light source. Generally speaking, the controller has two main light source control modes: constant light mode and strobe mode. In constant light mode, the light source remains illuminated at a set current or voltage value. In strobe mode, the light source controller illuminates the light source at specific moments and remains off at other times. This can instantly increase the light source's brightness several times without affecting its lifespan.

[0039] The controller in strobe mode provides instant brightness by controlling the light source device. Since the light source is on for a short time, the internal temperature rise of the light source device is suppressed, thus extending the service life of the light source device.

[0040] To precisely control N light source outputs and N camera control outputs, the controller processor requires at least 2N independent timers, each of which must support at least one PWM (Pulse Width Modulation) output. However, general-purpose processors typically support 3-5 (less than 2N) independent timers, making them incapable of meeting the 2N independent timer requirement.

[0041] In order to solve the above problems, some embodiments of the present application provide a strobe controller, such as Figure 1 As shown, the strobe controller includes N light source outputs, N camera outputs, and a processor. The processor has M timers (N≤M<2N), each of which is independent. Each timer includes a counter auto-reload register, a channel comparison register, a count register, and a channel control register.

[0042] For ease of description, in this embodiment, the counter auto-reload register is recorded as PERIOD; the channel comparison register is recorded as CHxVAL, where x is 0 for light source output and x is 1 for camera control output; the counting register is recorded as COUNT; and the channel control register is recorded as CHxCTL, where x is 0 for light source output and x is 1 for camera control output.

[0043] Each timer is configured as:

[0044] Obtain configuration information, including a preset light source output delay, a preset light source output pulse width, a preset camera output delay, and a camera output pulse width. For ease of description in this embodiment, the preset light source output delay is denoted as dch, the preset light source output pulse width is denoted as pch, the preset camera output delay is denoted as dtr, and the camera output pulse width is denoted as ptr.

[0045] The camera output pulse width is a fixed value. The units of the preset light source output delay, preset light source output pulse width, preset camera output delay, and camera output pulse width are in µs and are positive integers.

[0046] Determine whether the configuration information meets the configuration conditions, the configuration conditions being that the preset light source output delay is greater than the delay threshold, the preset light source output pulse width is greater than or equal to 0us and less than or equal to 999us, and the preset camera output delay is greater than or equal to the preset light source output delay and less than the sum of the preset light source output delay and the preset light source output pulse width. That is, the configuration conditions are that the preset light source output delay dch > delay threshold; the preset light source output pulse width pch > = 0us and the preset light source output pulse width pch = < 999us; the preset camera output delay dtr > = dch and the preset camera output delay dtr <dch+pch。

[0047] In one embodiment, the delay threshold may be set to 10 us. For general hardware, if the delay is within 10 us, software compensation is required to reach a state close to 10 us. At the same time, the delay threshold may also be set to 20 us.

[0048] When the configuration information does not meet the configuration conditions, the current configuration operation is terminated and the previous configuration information can be retained.

[0049] When the configuration information meets the configuration conditions, it is determined according to the configuration of the channel control register that the timer has one PWM mode output for light source output and one comparison mode output for controlling camera output, and the values ​​of the channel comparison register and the counting register are modified according to the configuration information, and the value of the counter automatic reload register is configured according to the configuration information.

[0050] The value of the counter automatic reload register is greater than the sum of the preset light source output delay and the preset light source output pulse width.

[0051] Modifying the values ​​of the channel comparison register and the counter register according to the configuration information includes:

[0052] The value of the counting register COUNT is the sum of the preset light source output pulse width and the preset light source output delay, that is, COUNT=dch+pch.

[0053] In PWM mode output (ie, light source output), the value of the channel comparison register CH0VAL (ie, the corresponding first value) is the preset light source output pulse width, ie, CH0VAL=pch.

[0054] In comparison mode output (i.e., controlling camera output), the value of the channel comparison register CH1VAL (i.e., the corresponding second value) is the sum of the preset light source output pulse width and the preset light source output delay minus the preset camera output delay, i.e., CH1VAL=dch+pch–dtr.

[0055] Configure the channel control register CH0CTL for PWM output mode, i.e., light source output; configure the channel control register CH1CTL for compare output mode, i.e., camera output control. The light source output controls the strobe lighting according to the preset light source output pulse width and preset light source output delay. Camera output controls the camera according to the camera output pulse width and preset camera output delay. Edge-triggered signals are typically used, outputting a rising edge signal from a low level to a high level, or a falling edge signal from a high level to a low level.

[0056] like Figure 2 As shown, the control camera output can be triggered by a rising edge, and the following embodiments of the present application will take the rising edge trigger as an example; the control camera output can also be triggered by a falling edge. Figure 2 In , time means as follows:

[0057] t0: starting time;

[0058] t1: The strobe controller receives an external rising edge trigger signal;

[0059] t2: The light source starts to output a high level;

[0060] t3: Control the camera to start outputting high level;

[0061] t4: The light source stops outputting;

[0062] t5: Control the camera to end output;

[0063] t6: The strobe controller ends the current trigger output and disables the timer counting function. During t1 to t6, it only responds to the trigger signal at time t1, and the trigger signal between t5 and t6 is ignored.

[0064] The configuration information must be confirmed before the trigger signal is received for the configuration to take effect.

[0065] A trigger signal is obtained, and a counting function of the timer is started.

[0066] When the light source is output, when the timer count value COUNT is equal to 0 for the first time, the light source output is turned off.

[0067] In one embodiment, the timer adopts a down-counting working mode. When the count value COUNT of the counting register is greater than the channel comparison register CH0VAL, that is, CH0VAL=pch, the timer outputs a low level; when the count value COUNT of the counting register is less than or equal to the channel comparison register CH0VAL, that is, CH0VAL=pch, the timer outputs a high level.

[0068] When controlling the camera output, the camera output will be turned off only when the second count value COUNT of the timer is equal to 0.

[0069] In one embodiment, Figure 2 As shown, at time t1, the count value COUNT of the count register in the timer is greater than the channel comparison register CH1VAL, and the output is low; at time t3, the count value COUNT of the count register in the timer is equal to the channel comparison register CH1VAL, and the output is high; at time t4, the count value COUNT of the count register in the timer is equal to 0, and the output is still high, and the counter starts counting the next cycle (counting down from the value PERIOD of the counter automatic reload register); at time t5, the count value COUNT of the count register in the timer is equal to the channel comparison register CH1VAL again, and the output is low.

[0070] For example, when precise control of four light source outputs and four camera control outputs is required, the processor in the strobe controller requires at least eight independent timers, and each of these eight timers supports at least one PWM (Pulse Width Modulation) output. However, general-purpose processors generally support three to five independent timers, which cannot meet the requirement for eight independent timers. This application enables a general-purpose processor (supporting at least four independent timers) to meet the requirements for controlling four light source outputs and four camera control outputs.

[0071] As can be seen from the above technical solution, the present application provides a strobe controller, including N light source outputs, N camera outputs, and a processor, wherein the processor has at least M timers (N≤M<2N), each timer including a channel comparison register, a count register, and a channel control register, and each timer is configured to: obtain configuration information, wherein the configuration information includes a preset light source output delay, a preset light source output pulse width, a preset camera output delay, and a camera output pulse width. When the configuration information meets the configuration conditions, the timer is determined to have one PWM mode output for light source output and one comparison mode output for controlling camera output according to the configuration of the channel control register, and the values ​​of the channel comparison register and the count register are modified according to the configuration information; a trigger signal is obtained, and the counting of the timer is started; according to the count value of the count register and the working mode of the timer, one light source output and one camera control output are obtained. The present application uses one timer to realize one light source output and one camera control output; reduces the requirements for the number of timers in the processor, reduces the difficulty of processor selection, and uses a general-purpose processor to realize the functions of the strobe controller.

[0072] Some embodiments of the present application provide an output control method for a strobe type controller, such as Figure 3 As shown, the output control method includes the following steps:

[0073] S101. Acquire configuration information, where the configuration information includes a preset light source output delay, a preset light source output pulse width, a preset camera output delay, and a camera output pulse width.

[0074] The camera output pulse width is a fixed value. The units of the preset light source output delay, preset light source output pulse width, preset camera output delay, and camera output pulse width are in µs and are positive integers.

[0075] S102. When the configuration information meets the configuration conditions, determine, according to the configuration of the channel control register, that the timer has one PWM mode output for light source output and one comparison mode output for controlling camera output, and modify the values ​​of the channel comparison register and the counter register according to the configuration information.

[0076] The value of the counting register COUNT is the sum of the preset light source output pulse width and the preset light source output delay, that is, COUNT=dch+pch.

[0077] In PWM mode output (ie, light source output), the value of the channel comparison register CH0VAL (ie, the corresponding first value) is the preset light source output pulse width, ie, CH0VAL=pch.

[0078] In comparison mode output (i.e., controlling camera output), the value of the channel comparison register CH1VAL (i.e., the corresponding second value) is the sum of the preset light source output pulse width and the preset light source output delay minus the preset camera output delay, i.e., CH1VAL=dch+pch–dtr.

[0079] S103: When the configuration information does not meet the configuration conditions, end the configuration operation.

[0080] At this point, you can keep the previous configuration information.

[0081] S104: Acquire a trigger signal and start counting of the timer.

[0082] S105 , obtaining one light source output and one camera control output according to the count value of the count register and the working mode of the timer.

[0083] When the light source is output, when the timer count value COUNT is equal to 0 for the first time, the light source output is turned off.

[0084] In one embodiment, the timer adopts a down-counting working mode. When the count value COUNT is greater than the channel comparison register CH0VAL, that is, CH0VAL=pch, the timer outputs a low level; when the count value COUNT is less than or equal to the channel comparison register CH0VAL, that is, CH0VAL=pch, the timer outputs a high level.

[0085] When controlling the camera output, the camera output will be turned off only when the second count value COUNT of the timer is equal to 0.

[0086] In one embodiment, Figure 2 As shown, at time t1, the timer count value COUNT is greater than the channel comparison register CH1VAL, and the output is low; at time t3, the timer count value COUNT is equal to the channel comparison register CH1VAL, and the output is high; at time t4, the timer count value COUNT is equal to 0, and the output is still high, and the counter starts counting the next cycle (counting down from the value PERIOD of the counter auto-reload register); at time t5, the timer count value COUNT is equal to the channel comparison register CH1VAL again, and the output is low.

[0087] As can be seen from the above technical solution, the present application provides an output control method for a strobe-type controller, including obtaining configuration information, wherein the configuration information includes a preset light source output delay, a preset light source output pulse width, a preset camera output delay, and a camera output pulse width. When the configuration information meets the configuration conditions, the timer is determined to have one PWM mode output for light source output and one comparison mode output for controlling camera output according to the configuration of the channel control register, and the values ​​of the channel comparison register and the counting register are modified according to the configuration information; a trigger signal is obtained, and the counting of the timer is started; according to the count value of the counting register and the working mode of the timer, one light source output and one camera control output are obtained. The present application uses a one-way timer to realize one-way light source output and one-way camera control output; reduces the requirements for the number of timers in the processor, reduces the difficulty of processor selection, and uses a general-purpose processor to realize the functions of the strobe-type controller.
