Description

Technical Field

[0001] This application relates to the field of indicator display control, and specifically relates to a method for synchronous and same-frequency flashing of indicators in a DCS, a device for synchronous and same-frequency flashing of indicators in a DCS, and a processor. Background Art

[0002] On the header APPBAR of the DCS control system, multiple indicators are supported for configuration. Each indicator is an independent program and there is no interaction during operation. Please refer to Figure 1 , the figure includes three upper computers A, B, and C. Among the above indicators, there are: between different indicators of the same upper computer (such as indicator 1.1, indicator 2.1, indicator 3.1); between indicators at the same position of different upper computers (such as indicator 1.1, indicator 1.2, indicator 1.3); between different indicators of different upper computers (such as indicator 1.1, indicator 2.2, indicator 3.3).

[0003] In the traditional DCS control system, each indicator modifies the display state of the indicator according to the running state of its own program, and can be displayed in flat light, highlighted, fast flashing, or slow flashing. Since there is no interaction between the indicators, even if the flashing frequencies are the same, due to the inconsistent start times between the indicators, the flashing of each indicator does not look synchronized. Each indicator has an independent flashing cycle, which seriously affects the operator's observation. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a method, device, and processor for synchronous and same-frequency flashing of indicators in a DCS, so as to keep the consistency of flashing between indicators that have no interaction with each other, which is beneficial for the operator to observe.

[0005] To achieve the above purpose, in the first aspect of this application, a method for synchronous and same-frequency flashing of indicators in a DCS is provided.

[0006] Based on the first aspect, in some embodiments of the present invention, the flashing frequency is Freq; the calculation formula for the flashing interval is as follows:

[0007] time_align = 1000 / (2 * Freq); (1)

[0008] In formula (1), time_align represents the flashing interval, and 1000 is the unit time of 1000 milliseconds.

[0009] Based on the first aspect, in some embodiments of the present invention, the calculation formula for the sleep time is as follows:

[0013] In formula (3), time_align represents the flashing interval, and % represents the modulo operation.

[0014] Based on the first aspect, in some embodiments of the present invention, when the current moment is the flashing moment of the reference indicator, the following numerical relationship exists between the sleep time sleep_period and the flashing interval time_align:

[0015] sleep_period = time_align.

[0016] Based on the first aspect, in some embodiments of the present invention, the display state includes a first display state and a second display state; predicting the display state of the reference indicator after the sleep time includes:

[0017] Let A = (next_time / time_align) % 2; (4)

[0018] When A = 0, the display state of the reference indicator after the sleep time is the first display state; when A = 1, the display state of the reference indicator after the sleep time is the second display state;

[0019] In formula (4), next_time represents the next flashing moment, time_align represents the time interval, and %2 represents taking the remainder of 2.

[0020] Second aspect, the present application provides a device for synchronous and same-frequency flashing of indicators in a DCS. The device includes: a setting module for setting the flashing frequency of the indicators; an acquisition module for determining the flashing interval for modifying the state of the indicators based on the flashing frequency; a calculation module for calculating the sleep time of the target indicator that joins the flashing at the current moment in combination with the flashing interval; a prediction module for predicting the display state of the reference indicator after the sleep time; and an execution module for making the target indicator be consistent with the display state of the reference indicator after the sleep time.

[0021] Based on the second aspect, in some embodiments of the present invention, the acquisition module calculates the flashing interval through the following formula:

[0022] time_align = 1000 / (2 * Freq); (1)

[0023] In formula (1), time_align represents the flashing interval, Freq represents the flashing frequency, and 1000 is 1000 milliseconds in the unit time.

[0024] Based on the first aspect, in some embodiments of the present invention, the calculation module calculates the sleep time through the following formula:

[0025] sleep_period = next_time - current_time; (2)

[0026] In formula (2), sleep_period represents the sleep time, next_time represents the next flashing moment, and current_time represents the current moment; wherein, the calculation formula for the next flashing moment next_time is as follows:

[0027] next_time = current_time - (current_time % time_align) + time_align; (3)

[0028] In formula (3), time_align represents the flashing interval, and % represents the remainder operation.

[0029] Based on the first aspect, in some embodiments of the present invention, the display state includes a first display state and a second display state; the prediction module predicts the display state of the reference indicator after the sleep time through the following method, including:

[0030] Let A = (next_time / time_align) % 2; (4)

[0036] 2) Support cross-host computer synchronization: Ensure the flashing synchronization between the same indicators of different host computers and the flashing synchronization between different indicators of different host computers, which is convenient for the collaborative work of multiple operators.

[0037] 3) High flexibility: The flashing frequency can be configured through a configuration file; if it is necessary to modify the flashing frequency, only the corresponding configuration file needs to be modified.

[0038] 4) Strong scalability: Each indicator is still an independent program, and the flashing start time and flashing frequency are processed inside the program. When adding or deleting some indicators, it will not affect the work of the remaining indicators.

[0039] 5) Fault controllability: When some indicators restart due to some other reasons, or after the host computer restarts, they can still be consistent with the flashing frequencies and flashing start times of other host computers, meeting the requirements of synchronous and same-frequency flashing.

[0056] Embodiment 1

[0057] The method for synchronously and equally flashing indicators in the DCS provided by the present application can be applied to an application environment as Figure 2 shown. Among them, the terminal 102 communicates with the server 104 through the network. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, and portable wearable devices, and the server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0058] Figure 3 Schematically shows a flowchart of the method for synchronously and equally flashing indicators in the DCS according to an embodiment of the present application. As Figure 3 shown, in this embodiment, a method for synchronously and equally flashing indicators in the DCS is provided, including the following steps:

[0059] S1. Set the flashing frequency of the indicator;

[0060] For example, the time frequency Freq of the indicator flashing can be customized through a configuration file: the frequency of fast flashing is Freq = 2, that is, the highlight and flat light are each twice within 1 s (as Figure 4 shown); the frequency of slow flashing is Freq = 0.5, that is, the highlight and flat light are each once within 2 s (as Figure 5 shown).

[0061] S2. Determine the flashing interval for the indicator to modify the state based on the flashing frequency (as Figure 4 shown, the time points marked by circles in the figure indicate the flashing moments, and the time interval between two adjacent flashing moments is the flashing interval defined in the present application);

[0062] Specifically, obtain the flashing interval time_align according to the flashing frequency, that is, the time interval for the indicator to modify the state within 1 second, and the unit of time_align is milliseconds:

[0063] time_align = 1000 / (2 * Freq); (1)

[0064] Among them, 1000 represents 1000 milliseconds, that is, 1 second; because in one flash frequency, the indicator state needs to be modified twice. That is, at the start of the flash, the indicator is modified to the highlighted state, and when the flash resumes, the indicator is modified to the flat light state. Therefore, the number of times the indicator state needs to be modified is the flash frequency * 2.

[0065] Therefore, the flash interval = the highlighted time = the flat light time.

[0066] S3. Combine the flash interval to calculate the sleep time of the target indicator that joins the flash at the current moment;

[0067] Specifically, the sleep time sleep_period is the time interval between the start time of the next flash cycle and the current time, that is:

[0068] sleep_period = next_time - current_time; (2)

[0069] next_time represents the next flash moment, and current_time is the current moment obtained through the interface provided by the DCS control system. The time synchronization program of the DCS control system ensures the stability of the clock in the system and high-precision clock synchronization. Each indicator obtains the time through the interface provided by the DCS control system, so that the time inside the program of each indicator always remains consistent.

[0070] Among them, the next flash moment next_time is the previous flash moment plus the flash interval, and the previous flash moment is the current time minus the time interval between the previous flash moment and the current time, that is:

[0071] next_time = current_time - (current_time % time_align) + time_align; (3)

[0072] In formula (3), time_align represents the flash interval, and % represents the modulo operation.

[0073] Furthermore, there are two cases for the current time point current_time (the time when the target indicator joins the flash):

[0074] 1) The target indicator joins the flash at the flash moment of the reference indicator (as Figure 6 shown);

[0075] At this time, current_time % time_align = 0, that is, next_time = current_time + time_align. At this time, the sleep time is equal to the blinking time interval, that is, sleep_period = time_align, which means that the sleep time to be slept is the entire blinking time interval. During the entire blinking time interval, the status of the target indicator remains unchanged. After the sleep time, that is, at the next blinking moment, the target indicator changes its blinking status with the reference indicator and blinks synchronously (changing from high-brightness display to flat-light display, or from flat-light display to high-brightness display).

[0076] 2) The target indicator starts blinking at a non-blinking moment of the reference indicator (as Figure 7 shown);

[0077] At this time, the blinking time interval is greater than or equal to the sleep time, that is, time_align >= sleep_period, which means that the sleep time to be slept is sleep_period = next_time - current_time. In order to maintain blinking synchronization between different indicators of this host computer, between the same indicator of different host computers, and between different indicators of different host computers, the current moment will not immediately display in high brightness, but will blink together with other indicators at the next blinking moment.

[0078] S4. Predict the display status of the reference indicator after the sleep time;

[0079] Specifically, the display status of the indicator includes two types: the first display status (high brightness) and the second display status (flat light). By dividing the next blinking moment by the blinking time interval, the number of blinking phases experienced by the current indicator is obtained. Taking the remainder of the number of blinking phases of the indicator by 2, the blinking status of the target indicator after the sleep time is obtained. Let: A = (next_time / time_align) % 2; (4)

[0080] In formula (4), next_time represents the next blinking moment, time_align represents the time interval, and % 2 represents taking the remainder by 2.

[0081] If A = 0, it means that the display status of the reference indicator after the sleep time is the first display status;

[0082] If A = 1, it means that the display status of the reference indicator after the sleep time is the second display status.

[0083] S5. Make the display status of the target indicator consistent with that of the reference indicator after the sleep time.

[0084] Embodiment 2

[0085] In this embodiment, as Figure 8 shown, a device for synchronous and same-frequency flashing of indicators in a DCS is provided, including: a setting module 1 for setting the flashing frequency of the indicators; an acquisition module 2 for determining the flashing interval for modifying the status of the indicators based on the flashing frequency; a calculation module 3 for calculating the sleep time of the target indicator that joins the flashing at the current moment in combination with the flashing interval; a prediction module 4 for predicting the display status of the reference indicator after the sleep time; and an execution module 5 for making the target indicator be consistent with the display status of the reference indicator after the sleep time.

[0086] Further, the acquisition module 1 calculates the flashing interval through the following formula:

[0087] time_align = 1000 / (2 * Freq); (1)

[0088] In formula (1), time_align represents the flashing interval, Freq represents the flashing frequency, and 1000 is 1000 milliseconds of the unit time.

[0089] Further, the calculation module 3 calculates the sleep time through the following formula:

[0090] sleep_period = next_time - current_time; (2)

[0091] In formula (2), sleep_period represents the sleep time, next_time represents the next flashing moment, and current_time represents the current moment; among them, the calculation formula for the next flashing moment next_time is as follows:

[0092] next_time = current_time - (current_time % time_align) + time_align; (3)

[0093] In formula (3), time_align represents the flashing interval, and % represents the modulo operation.

[0094] Further, the display status includes a first display status and a second display status; the prediction module 4 predicts the display status of the reference indicator after the sleep time through the following method, including:

[0095] Let A = (next_time / time_align) % 2; (4)

[0096] When A = 0, the display state of the reference indicator after the sleep time is the first display state; when A = 1, the display state of the reference indicator after the sleep time is the second display state; in formula (4), next_time represents the next flashing moment, time_align represents the time interval, and %2 represents the remainder when divided by 2.
