Step 302, obtaining the longest time for the spherical element to pass between any two adjacent counters according to the distance set between each counter and the preset minimum speed of the spherical element.
Step 302 in this embodiment is substantially the same as step 101 in the first embodiment, and will not be described here.

In addition, the position of the counter and the pulse time width of the counter are sequentially adjusted, so that the situation of miscounting or missing counting can be avoided, and the accuracy of the counting method is further improved.
The fourth embodiment of the application relates to a counting method which is applied to a high-temperature gas-cooled reactor fuel loading and unloading system, wherein the system comprises a spherical element and a counting device, the counting device at least comprises three counters which are sequentially arranged in a loading and unloading pipeline, and the counting method is shown in fig. 5 and specifically comprises the following steps:
step 501, obtaining an identifier of each counter based on the total number of counters and the location of each counter in the loading and unloading pipeline.
Step 502, obtaining the longest time for the spherical element to pass through between any two adjacent counters according to the distance set between each counter and the preset minimum speed of the spherical element.
Step 502 in this embodiment is substantially the same as step 101 in the first embodiment, and will not be described here.
In step 503, when the ball-shaped element passes through the loading and unloading pipeline, the number of valid counters and the number of invalid counters are obtained, wherein the valid counter indicates that the next counter has a count within the longest time after the last counter counts, and the invalid counter indicates that the next counter has not counted within the longest time after the last counter counts.
Step 504, when the number of valid counters is greater than the number of invalid counters, the number of spherical elements passing through the loading and unloading pipeline is obtained according to the valid counters.
Step 505, automatically identifying the invalid counter and the number of missed counts of the invalid counter according to the identifier of the valid counter and the number of counts of the valid counter.
Specifically, step 505 may be implemented by using a basic logic gate circuit, taking the counting device of 3 counters in fig. 2 as an example, the counter a and the counter B may be taken as an and output X1, X1 represents that the counter a and the counter B are valid counts, the counter a and the counter C are taken as an and output Y1, Y1 represents that the counter a and the counter C are valid counts, the counter B and the counter C are taken as an and output Z1, Z1 represents that the counter B and the counter C are valid counts, AB count is unsuccessful (X1 is inverted), AC count is unsuccessful (Y1 is inverted), BC count success (Z1) is taken as an and logic for the counter a to be missed; taking the logic of the AND logic of unsuccessful AB count (X1 negation) and successful AC count (Y1) and unsuccessful BC count (Z1 negation) as the leakage of the B counter; the AB count was successful (X1), the AC count was unsuccessful (Y1 was inverted), and the BC count was unsuccessful (Z1 was inverted) and logic was left as the C counter miss.
And step 506, when the missed count exceeds a preset threshold, sending an alarm prompt message to the counting device, wherein the alarm prompt message comprises an identifier of the invalid counter.
Compared with the prior art, the embodiment of the application has the advantages that at least three counters are sequentially arranged in the loading and unloading pipeline to obtain the number of the effective counters and the number of the ineffective counters when the spherical elements move, when the number of the effective counters is larger than the number of the ineffective counters, the counting device is indicated to count successfully, the number of times that the spherical elements pass through the loading and unloading pipeline can be obtained through the effective counters, and the counters are in contrast or reference with each other, so that the condition of missing or missing counting can be accurately avoided, and the number of times of passing balls in the loading and unloading pipeline of the high-temperature gas cooled reactor can be simply, accurately and rapidly obtained. In addition, the invalid counter can be quickly positioned by sending an alarm prompt message to the counter setting, so that the missing counting reason is further analyzed.

Further, as shown in fig. 7, the counting device further includes:
and the alarm prompting module 603 is configured to send an alarm prompting message to the counting device when the missed count exceeds a preset threshold, where the alarm prompting message includes an identifier of an invalid counter.

TABLE 1
Note that in fig. 9, OR (block 33) indicates that any of AND (block 24), AND (block 28), AND (block 32) is triggered, since the A, B, C counter is a sequential count AND the trigger time is short, it may happen that the A, B, C counter counts in turn, TP01, TP02 is triggered AND held for 6 seconds simultaneously (assuming that the maximum time for a spherical element to pass between any two adjacent counters is 3 seconds), AND TP03 is triggered AND held for 3 seconds at the time of B triggering. AND (block 24) triggers AND remains the same time as B when B triggers AND (block 28), AND (block 32) triggers AND remains the same time as C when C triggers. At this time, the OR (block 33) will trigger 2 times, but only 1 spherical element is actually used, if the output of the OR (block 33) is used as the count determination of the 3-out-of-2 counter, the count value will not be consistent with the actual number of goals. To avoid this, TP07 is added after OR (block 33), and for the case of 1 spherical element passing ball, since the time from the start of the 1 st trigger to the end of the 2 nd trigger of OR (block 33) is necessarily less than 3 seconds, the time of TP07 takes 3 seconds, which means that the short pulse of OR (block 33) is prolonged to 3 seconds long pulse at the 1 st trigger, so that the 2 nd trigger is filtered out, ensuring that the count value is consistent with the number of passing balls.
In addition, the module 47 is a delay module TON01, the delay time is 3 seconds (assuming that the maximum time that the spherical element passes between any two adjacent counters is 3 seconds), where the TON module plays a role in filtering invalid pulses, and cannot be omitted. If the delay block is not used, the AND (46) is directly connected to CL (like AL, BL), considering the case where the A, B, C counter counts normally in turn, where X1 will trigger AND hold for 4 seconds when B triggers, Y1 AND Z1 will trigger AND hold for 4 seconds when C triggers, C is missed on condition that X1 AND Y1 (inverse) AND Z1 (inverse), since B, C counter detects an overball in turn, x1=1 when the ball reaches B counter, where the ball has not reached C counter, Y1 (inverse) =1, Z1 (inverse) =1, Y1 (inverse) =0, Z1 (inverse) =0 when the ball reaches C counter. When the ball is in the middle of the B, C counter, CL is false triggered, i.e., C is considered to be missed 1 time.
It is not difficult to find that the module in the present embodiment is a system example corresponding to the first embodiment, and thus the present embodiment can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and in order to reduce repetition, a detailed description is omitted here.
