Step 101: collecting voltage values of the isolation module at least once; the voltage values of the isolation module include input end voltage values and output end voltage values. Specifically, first of all, it needs to be pointed out that the execution subject of the embodiment is any isolation module in the fire-fighting system, which is used to realize short-circuit detection of the fire-fighting system based on the isolation module, so as to improve the accuracy and reliability of the short-circuit detection.

[0029] The fire-fighting system comprises a main control board, at least one isolation module and fire-fighting peripherals corresponding to each isolation module, for example, Figure 2 Figure 2 is one of schematic diagrams of a topological structure of a fire-fighting system provided by the application, Figure 3 Figure 3 is another schematic diagram of a topological structure of a fire-fighting system provided by the application, as shown in the figure, Figure 2 The topological structure of the fire-fighting system is a tree-shaped topological structure, as shown in the figure, Figure 3 The topological structure of the fire-fighting system is a ring-shaped topological structure, and the isolation module is usually used in a ring-shaped and tree-shaped topological structure in the actual application of the fire-fighting system. When the total length of the wiring line is less than or equal to 1200 meters (m), the ring-shaped topological structure is usually adopted, and when the total length of the wiring line is greater than 1200 m, the tree-shaped topological structure is adopted. The advantage of using the ring-shaped topological structure lies in that the redundant line is increased, and the system stability is improved.

[0030] The method for line short-circuit detection of the isolation module provided by the embodiment is as follows: First, initialization is performed. The relay corresponding to the input end of the isolation module and the relay corresponding to the output end of the isolation module are closed, so that the input end and the output end of the isolation module are conducted; the input end threshold voltage is initialized to obtain an initial input end threshold voltage; and the output end threshold voltage is initialized to obtain an initial output end threshold voltage. Specifically, the input and output end short-circuit indicator lights of the isolation module are extinguished, the relays of the input and output ends are closed to make the input and output ends conducted, and the initial values of the input and output end short-circuit threshold voltages are and Further, the input and output terminal voltages are collected. The voltage value of the isolation module is collected at least once, wherein the voltage value of the isolation module includes the input terminal voltage value and the output terminal voltage value. Specifically, the input and output terminal relays are closed, the AD voltage collection is started, and the input and output terminal voltage values are collected respectively. In one collection process, 10 times are collected respectively, and the last 5 times are taken respectively and averaged to obtain the input and output terminal voltage values, which are denoted as and respectively. The last 5 times are taken because the first few measurements are inaccurate after the AD is started. After the collection is completed, the AD is closed (energy saving). The collected input and output terminal voltage values and are stored in arrays and respectively.

[0031] Step 102, based on the current voltage collection times, determine whether the isolation module meets the threshold voltage update condition; the threshold voltage includes the input terminal threshold voltage and the output terminal threshold voltage, the input terminal threshold voltage is the threshold corresponding to the input terminal voltage value, and the output terminal threshold voltage is the threshold corresponding to the output terminal voltage value; Specifically, after the input and output terminal voltage values are collected, before the short circuit detection based on the isolation module is performed, the threshold voltage can be dynamically adjusted based on the real-time collected circuit parameters (input and output terminal voltages).

[0032] For example, first, based on the current voltage collection times, determine whether the isolation module meets the threshold voltage update condition. The threshold voltage includes the input terminal threshold voltage and the output terminal threshold voltage, the input terminal threshold voltage is the threshold corresponding to the input terminal voltage value, and the output terminal threshold voltage is the threshold corresponding to the output terminal voltage value. The current voltage collection times n is, for example, 100 times, 200 times, or 500 times. In one collection process, 10 times are collected respectively, and the last 5 times are taken respectively and averaged to obtain the input and output terminal voltage values.

[0033] Further, based on the current voltage collection times, determine whether to update the threshold voltage, for example, compare the current voltage collection times with the preset collection times threshold, and determine whether to update the threshold based on the comparison result.

[0034] Step 103, in the case where it is determined that the isolation module meets the threshold voltage update condition, update the threshold voltage according to the current collected voltage value of the isolation module, to obtain the updated threshold voltage; Specifically, in the case where it is determined that the isolation module meets the threshold voltage update condition, the threshold voltage can be updated according to the current collected voltage value of the isolation module, to obtain the dynamically adjusted updated threshold voltage.

[0035] The current collected voltage value of the isolation module includes an input end voltage value and an output end voltage value. Then, short circuit detection can be performed based on the updated threshold voltage. For example, the input end threshold voltage is updated by using the current collected input end voltage value of the isolation module, and the output end threshold voltage is updated by using the current collected output end voltage value of the isolation module.

[0036] In step 104, whether a short circuit occurs in a line to which the isolation module is connected is determined based on the updated threshold voltage and the current collected voltage value of the isolation module. The line is connected to the fire-fighting external device corresponding to each isolation module.

[0037] Specifically, after the updated threshold voltage is determined, whether a short circuit occurs in the line to which the isolation module is connected can be determined based on the updated threshold voltage and the current collected voltage value of the isolation module. The line is connected to the fire-fighting external device corresponding to each isolation module.

[0038] For example, the current collected voltage value of the isolation module is compared with the updated threshold voltage to determine whether a short circuit occurs.

[0039] The method provided in the embodiment is applied to any isolation module in a fire-fighting system. The fire-fighting system includes a main control board, at least one isolation module, and a fire-fighting external device corresponding to each isolation module. The method includes the following steps. First, a voltage value of the isolation module is collected at least once. The voltage value of the isolation module includes an input end voltage value and an output end voltage value. Then, whether the isolation module meets an update condition of a threshold voltage is determined based on a current voltage collection frequency. The threshold voltage includes an input end threshold voltage and an output end threshold voltage. The input end threshold voltage is a threshold value corresponding to the input end voltage value. The output end threshold voltage is a threshold value corresponding to the output end voltage value. In a case where it is determined that the isolation module meets the update condition of the threshold voltage, the threshold voltage is updated according to the current collected voltage value of the isolation module, to obtain an updated threshold voltage. Then, whether a short circuit occurs in a line to which the isolation module is connected is determined based on the updated threshold voltage and the current collected voltage value of the isolation module. The line is connected to the fire-fighting external device corresponding to each isolation module.

[0040] In the application, whether the isolation module meets the update condition of the threshold voltage is determined based on the current voltage collection frequency. In a case where it is determined that the isolation module meets the update condition of the threshold voltage, the threshold voltage is updated according to the current collected voltage value of the isolation module. Then, whether a short circuit occurs in a line to which the isolation module is connected is determined based on the updated threshold voltage and the current collected voltage value of the isolation module. The line is connected to the fire-fighting external device corresponding to each isolation module. The application realizes adaptive short circuit detection. In the application, the threshold voltage of the isolation module can be dynamically adjusted according to real-time monitored circuit parameters. The accuracy and reliability of short circuit detection of the isolation module in the fire-fighting system are improved.

[0041] According to the adaptive short-circuit detection method of the fire extinguishing system provided by the application, whether the isolation module meets the update condition of the threshold voltage is determined based on the current voltage collection frequency, including: obtaining a preset collection frequency threshold value; comparing the current voltage collection frequency with the preset collection frequency threshold value; in the case where it is determined that the current voltage collection frequency is greater than or equal to the preset collection frequency threshold value, it is determined that the isolation module meets the update condition of the threshold voltage; in the case where it is determined that the current voltage collection frequency is less than the preset collection frequency threshold value, it is determined that the isolation module does not meet the update condition of the threshold voltage.

[0042] Specifically, in some embodiments, the implementation process of step 102 of determining whether the isolation module meets the update condition of the threshold voltage based on the current voltage collection frequency includes the following steps: First, obtain a preset collection frequency threshold value. For example, set the input and output terminal voltage collection frequency to M (in the application, the value of M is 1000 by default, and the update duration is about 10 minutes).

[0043] Further, compare the current voltage collection frequency with the preset collection frequency threshold value. In the case where it is determined that the current voltage collection frequency is less than the preset collection frequency threshold value, it is determined that the isolation module does not meet the update condition of the threshold voltage, and then the initial threshold voltage is directly used for short-circuit detection judgment. In the case where it is determined that the current voltage collection frequency is greater than or equal to the preset collection frequency threshold value, it is determined that the isolation module meets the update condition of the threshold voltage, and then the threshold voltage is updated.

[0044] The method provided in this embodiment, by obtaining a preset collection frequency threshold value, then comparing the current voltage collection frequency with the preset collection frequency threshold value, judging whether to update the threshold voltage based on the comparison result, updating the threshold voltage in the case where it is determined that the isolation module meets the update condition of the threshold voltage, and then determining whether the line connected to the isolation module has a short circuit based on the updated threshold voltage and the voltage value of the isolation module collected at present, adaptive short-circuit detection is realized. In the application, the threshold voltage of the isolation module can be dynamically adjusted according to the real-time monitored circuit parameters, and the accuracy and reliability of the short-circuit detection of the isolation module for the fire extinguishing system are improved.

[0045] According to the adaptive short-circuit detection method of the fire extinguishing system provided by the application, the updated threshold voltage includes an updated input terminal threshold voltage; the threshold voltage is updated based on the input terminal voltage value in the voltage value of the isolation module collected at present, and the updated threshold voltage is obtained, including: constructing a first array based on the input terminal voltage value in the voltage value of the isolation module collected at present; Sum all elements in the first array to obtain a sum result of the first array; Divide the sum result of the first array by the preset acquisition frequency threshold to obtain a first average value; Determine a first standard deviation based on all elements in the first array, the first average value, and the preset acquisition frequency threshold; Construct a first confidence interval based on the first average value, the first standard deviation, and the current voltage acquisition frequency; Determine the minimum critical value of the first confidence interval as the updated input terminal threshold voltage.

[0046] Specifically, it should be noted that the updated threshold voltage includes the updated input terminal threshold voltage and the updated output terminal threshold voltage.

[0047] Correspondingly, the specific implementation process of updating the threshold voltage according to the current acquired voltage value of the isolation module in step 103 includes the following steps: If the acquisition frequency reaches the preset acquisition frequency threshold M times, update the threshold value. At this time, and respectively have M times of input and output terminal voltage values. The following takes as an example to illustrate the threshold value update.

[0048] Construct a first array based on the input terminal voltage value in the current acquired voltage value of the isolation module, wherein, conforms to the normal distribution, and let be the th element in the first array, ( ).

[0049] Further, the average value of all elements in the first array is obtained as follows: Sum all elements in the first array to obtain a sum result of the first array; divide the sum result of the first array by the preset acquisition frequency threshold to obtain a first average value, for example, the average value of all elements in the first array is obtained by using the following formula: wherein, represents the average value of the input terminal voltage value, is the preset acquisition frequency threshold, represents the i th element in the first array, and the first array has a total of M elements.

[0050] Further, the standard deviation of all elements in the first array is obtained as follows: Determine the first standard deviation based on all elements in the first array, the first average value, and a preset acquisition frequency threshold, for example, the average value of all elements in the first array is obtained by using the following formula: wherein, represents the standard deviation of the input terminal voltage value, is the preset acquisition frequency threshold, represents the i-th element in the first array, and the first array has M elements in total, represents the average value of the input terminal voltage value.

[0051] Further, the first confidence interval is constructed based on the first average value, the first standard deviation, and the current voltage acquisition frequency. Specifically, in the present application, the voltage value is continuously acquired for n times, and if the n times of results are all less than the threshold value, it is considered that a short circuit occurs. If the confidence level is set to 95%, the average value The confidence interval under the confidence level of 95% is: wherein z is the critical value corresponding to the confidence level of 95%, and the value is 1.96.

[0052] Further, the minimum critical value of the first confidence interval is determined as the updated input terminal threshold voltage. The input terminal voltage threshold is updated To 。

[0053] It should be noted that the updated input and output terminal voltage thresholds are usually greater than the default value (the default value is smaller in order to avoid false short circuit when the isolation module is just started), and the updated voltage threshold will become larger, so that the determination of the line short circuit is more sensitive.

[0054] The method provided by the embodiment first constructs a first array based on the input terminal voltage value in the currently acquired voltage value of the isolation module, and calculates the average value and the standard deviation of all elements in the first array; then, the first confidence interval is constructed based on the first average value, the first standard deviation, and the current voltage acquisition frequency; further, the minimum critical value of the first confidence interval is determined as the updated input terminal threshold voltage, which realizes the updating of the input terminal threshold voltage based on the currently acquired circuit parameters, dynamically adjusts the threshold value, and further improves the accuracy and reliability of the short circuit detection based on the threshold value.

[0055] According to the adaptive short circuit detection method of the fire-fighting system provided by the present application, the updated threshold voltage includes the updated output terminal threshold voltage, the threshold voltage is updated according to the currently acquired voltage value of the isolation module, and the updated threshold voltage is obtained, including: constructing a second array based on the output terminal voltage value in the current collected voltage value of the isolation module; summing all elements in the second array to obtain a summation result of the second array; dividing the summation result of the second array by the preset collection number threshold to obtain a second average value; determining a second standard deviation based on all elements in the second array, the second average value, and the preset collection number threshold; constructing a second confidence interval based on the second average value, the second standard deviation, and the current voltage collection number; determining the minimum critical value of the second confidence interval as the updated output terminal threshold voltage.

[0056] Specifically, the threshold voltage is updated based on the current collected voltage value of the isolation module to obtain an updated threshold voltage, and the output terminal threshold voltage is dynamically updated. The updating process refers to the updating process of the input terminal threshold voltage, as follows: First, a second array is constructed based on the output terminal voltage value in the current collected voltage value of the isolation module, and then a second average value and a second standard deviation are obtained from the second array. Then, a second confidence interval is constructed based on the second average value, the second standard deviation, and the current voltage collection number. The minimum critical value of the second confidence interval is determined as the updated output terminal threshold voltage.

[0057] Exemplarily, complying with normal distribution, let the i-th element in the second array be the number of elements in the second array be .

[0058] Then the average value of the output terminal voltage value is: wherein, the average value of the output terminal voltage value is represented by M, which is the preset collection number threshold, the i-th element in the second array, and the second array has M elements in total.

[0059] The standard deviation of the output terminal voltage value is: wherein, the standard deviation of the output terminal voltage value is represented by M, which is the preset collection number threshold, the i-th element in the second array, and the second array has M elements in total, the average value of the input terminal voltage value.

[0060] ​In the present application, n times of voltage are continuously collected, if n times of results are all less than the threshold voltage of the output end, it is considered that short circuit occurs at the output end. If the confidence level is set to 95%, the average value The confidence interval at the confidence level of 95% is Wherein z is the critical value corresponding to the confidence level of 95%, and the value is 1.96. The output end voltage threshold is updated to .

[0061] The method provided by the embodiment first constructs a second array based on the input end voltage value in the voltage value of the isolation module collected at present, and calculates the average value and the standard deviation of all elements in the second array; then, a second confidence interval is constructed based on the second average value, the second standard deviation, and the current voltage collection times; further, the minimum critical value of the second confidence interval is determined as the updated output end threshold voltage, which realizes updating the output end threshold voltage based on the circuit parameters collected at present, dynamically adjusts the threshold, and further improves the accuracy and reliability of short circuit detection based on the threshold.

[0062] According to the adaptive short circuit detection method of the fire fighting system provided by the present application, whether the line connected with the isolation module appears short circuit is determined based on the updated threshold voltage and the voltage value of the isolation module collected at present, which comprises the following steps. Based on the voltage value of the isolation module collected at present, the input end voltage value and the output end voltage value of continuous preset number of times are determined. If the input end voltage value and the output end voltage value of continuous preset number of times are all less than the threshold voltage, it is determined that the line connected with the isolation module appears short circuit. The line connected with the isolation module includes the incoming line end and the outgoing line end.

[0063] Specifically, in some embodiments, the implementation process of step 104 of determining whether the line connected with the isolation module appears short circuit based on the updated threshold voltage and the voltage value of the isolation module collected at present comprises the following steps. First, based on the voltage value of the isolation module collected at present, the input end voltage value and the output end voltage value of continuous preset number of times are determined. It should be noted that if the circuit parameter voltage value collected once is used to judge, the accuracy of the short circuit detection result may be reduced. In order to improve the accuracy of detection, the input end voltage value and the output end voltage value of continuous preset number of times can be used for judgment in the present embodiment, and further, the detection accuracy is improved.

[0064] Further, if the input end voltage value and the output end voltage value of continuous preset number of times are all less than the threshold voltage, it is determined that the line connected with the isolation module appears short circuit.

[0065] For the input and output ends, if the voltage collection results of continuous n times are all less than the threshold voltage, it is considered that a short circuit occurs. The accessed line includes an incoming line end and an outgoing line end, the incoming line end corresponds to the detection result of the input end, and the outgoing line end corresponds to the detection result of the output end.

[0066] The method provided in the embodiment determines whether the line accessed by the isolation module has a short circuit by comparing the input end voltage value and the output end voltage value with the threshold voltage for continuous preset number of times, and improves the accuracy of the short circuit detection result.

[0067] According to the adaptive short circuit detection method of the fire-fighting system provided in the application, the method further comprises: In the case where it is determined that the line accessed by the isolation module has a short circuit, the connection between the input end and the output end in the isolation module is cut off; The short circuit information is reported to the main control board card, and the short circuit information at least includes a short circuit indication bit and the self address of the isolation module.

[0068] Specifically, in some embodiments, the method further comprises reporting the short circuit information, and the process is as follows: In the case where it is determined that the line accessed by the isolation module has a short circuit, the connection between the input end and the output end in the isolation module is cut off, so as to avoid the influence of the short circuit of the input or output end on the normal operation of the other side line.

The line 1 refers to the line between the upper side of the main control board card and the fire-fighting peripheral N, and the line 2 refers to the line between the lower side of the main control board card and the fire-fighting peripheral N. If the fire-fighting peripheral N in the line 1 has a short circuit, the isolation module 2 detects the line short circuit, and cuts off all the output end lines (fire-fighting peripherals K+1 to N in the line 1) of the isolation module 2, while the fire-fighting peripherals 1 to K in the line 1 work normally.

If the fire-fighting peripheral M in the above figure has a short circuit, the isolation module 2 output end and the isolation module 3 input end will detect the line short circuit, all lines (fire-fighting peripheral K+1 to fire-fighting peripheral M) of the isolation module 2 output end and the isolation module 3 input end are cut off, and other modules operate normally. Line 1 refers to the line between the upper side of the main control board card and the fire-fighting peripheral N, and line 2 refers to the line between the lower side of the main control board card and the fire-fighting peripheral N.

[0071] Further, after cutting off the line, the further isolation module reports the short circuit information to the main control board card; the short circuit information at least includes: a short circuit indication bit and the address of the isolation module, wherein the short circuit indication bit is used to mark whether the input end or the output end is short-circuited, and the address of the isolation module is convenient for the main control board card to quickly locate the line short circuit position in the actual environment, and realize quick fault positioning.

[0072] The method provided by the embodiment can make the input and output ends of the isolation module cut off the connection between the input and output ends if the isolation module detects a short circuit, so as to avoid affecting the normal operation of the line on the other side due to the short circuit of the input or output end. At the same time, the short circuit information is reported to the main control board card, so as to realize quick fault positioning.

[0075] Step 403, satisfy the threshold update condition.

[0076] If the execution result of step 403 is yes, step 404 is executed: Step 404, update the input and output end threshold voltage.

[0077] If the execution result of step 403 is no, step 405 is executed: Step 405, judge whether there is a short circuit based on the initial threshold voltage.

[0078] If the execution result of step 405 is yes, step 406 is executed: Step 406, report the short circuit information to the main control board card according to the short circuit condition.

[0079] ​If the execution result of step 405 is no, return to step 402.
