Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention is further described in detail below with reference to the accompanying drawings and examples.
Example 1:
as shown in fig. 1, the present embodiment provides a monitoring system for compensating a rod position, which includes a controller 1, a rod position measuring device 2, and a display device 3.
And the rod position measuring devices 2 are used for measuring the rod position values of the compensation rods, and the number of the rod position measuring devices 2 is matched with that of the compensation rods, namely one compensation rod corresponds to one rod position measuring device.
And the controller 1 is connected with the rod position measuring devices 2 and is used for screening the rod position values measured by the rod position measuring devices 2 to obtain the highest rod position value, the lowest rod position value and the marks of the compensation rods corresponding to the highest rod position value and the lowest rod position value.
The display device 3 is connected with the controller 1, and the display device 3 comprises a first display unit 31 and the first display unit 31 is used for displaying the highest rod position value, the lowest rod position value and the identification of the compensation rod corresponding to the highest rod position value and the lowest rod position value.
In this embodiment, if the number of the compensation rods is 15, the controller 1 compares and screens the measurement results obtained by the 15 rod position measurement devices 2, and screens out the corresponding relationship between the highest rod position value and the identifier of the compensation rod and the corresponding relationship between the lowest rod position value and the identifier of the compensation rod, as shown in fig. 2, the first display unit 31 of the display device 3 displays the corresponding relationship between the highest rod position value and the identifier of the compensation rod and displays the corresponding relationship between the lowest rod position value and the identifier of the compensation rod.
Optionally, the controller 1 is further configured to sort the rod position values measured by the plurality of rod position measuring devices 2, and obtain a result of sorting the identifiers of the compensation rods and their rod position values, wherein the identifiers are sorted in ascending order of rod position values or descending order of rod position values. The display device 3 further includes a second display unit 32, the second display unit 32 being configured to display the marks of the compensation sticks arranged in the ascending order of the stick position values or the descending order of the stick position values and the sorting results of the stick position values thereof.
In this embodiment, when the controller 1 performs descending sorting on the rod position values measured by the 15 rod position measuring devices 2 to obtain a sorting result, the second display unit shown in fig. 2 is configured to display the sorting result obtained by the controller 1, where the sorting result includes the identifier of the compensation rod, the rod position value, the sorting number, and the corresponding relationship among the identifier, the rod position value, the sorting number, and the sorting number.
Optionally, the monitoring system of the compensation rod position further comprises a fault detection device 4. The number of the fault detection devices is matched with that of the compensation rods, namely one compensation rod corresponds to one fault detection device, and each fault detection device is connected with each compensation rod respectively and used for detecting faults related to the compensation rods. Wherein the single failure detection device 4 comprises a first detection unit 41, a second detection unit 42 and a third detection unit 43.
And a first detecting unit 41 for detecting whether the motor driving device of the corresponding compensation rod is out of order and outputting a first failure signal when the failure is detected.
And a second detecting unit 42 for detecting whether the rod position measuring device of the corresponding compensation rod is failed, and outputting a second failure signal when the failure is detected.
And a third detecting unit 43 for detecting whether the gripper position measuring device of the corresponding compensation rod is out of order, and outputting a third failure signal when the failure is detected.
The controller 1 is connected with a plurality of fault measuring devices 4 respectively and is used for carrying out fault alarm according to the first fault signal, the second fault signal or the third fault signal.
Optionally, the display device 3 further comprises a third display unit 33, and the controller 1 is further configured to send the identifier of the compensation rod with the fault alarm to the third display unit 33, so that the third display unit 33 displays the identifier of the compensation rod with the fault alarm. That is, when any one of the motor driving device, the rod position measuring device, and the grip position measuring device of one compensation rod malfunctions, the controller 1 will perform a malfunction alarm, and the third display unit 33 will perform a malfunction alarm display on the identification of the malfunctioning compensation rod.
The malfunction warning display may adopt different colors to distinguish the malfunction from the normal state, and as shown in fig. 2, when the malfunction of the motor driving apparatus of the compensation rod No. 1 is detected, the rod No. 1 malfunction lamp in the third display unit 33 displays red to indicate that the compensation rod No. 1 is malfunctioning. Alternatively, the other compensating rod failure lamps in the third display unit 33, which do not detect the failure, display green to indicate a normal state.
It should be noted that the monitoring system for the rod position of the compensation rod of the embodiment may be an independent whole set of equipment, or may be mounted on a computerized monitoring system of a control room of a nuclear power plant, and the computerized monitoring system is used as an upper computer of an instrumentation and control system, and can display collected field data to an operator, or transmit a control command of the operator to a lower computer and field equipment. In a instrumentation and control system for a nuclear power plant, a lower computer transmits rod position measurements of a compensation rod to a computerized monitoring system.
The monitoring system of compensation stick position of this embodiment compares in current scheme and shows the stick position value of a plurality of compensation sticks simultaneously on the display interface, and the disordered and disorderly arrangement of a plurality of stick position values compares on the display interface, and this monitoring system can show the sign of the compensation stick that highest stick position value or minimum stick position value and its each corresponds fast to promote the judgement efficiency of the compensation stick of highest stick position value or minimum stick position value. For example, when the rod positions of 19 compensation rods are not listed in any sort in the display interface, the operator looking for the desired compensation rod to be lifted/dropped will need to compare the rod positions of all compensation rods one by one. If the operator needs to search for the compensation rod with the lowest rod position value, when the operator searches through the human eyes, the operator needs to take a long time to locate the rod position with the lowest rod position of 1987.98 for the very close rod position values of 1988.12, 1988.00, 1988.00 and 1987.98, and when the brain load of a person is high, the judgment error is easy, but the monitoring system in the embodiment cannot generate the judgment error.
Example 2:
the embodiment provides a method for judging balance of an adjusting rod and a bar grid, which comprises the following steps:
monitoring the rod position of the compensating rod by using the monitoring system for the rod position of the compensating rod described in the embodiment 1;

and when the rod position value of the adjusting rod is smaller than the lower limit threshold value of the adjusting band, the compensating rod corresponding to the highest rod position value displayed by the first display unit of the monitoring system is inserted downwards so that the rod position value of the adjusting rod returns to the adjusting band, and therefore rod grid balance of the adjusting rod is achieved.
Optionally, before selecting to lift the compensation rod corresponding to the lowest rod position value displayed by the first display unit of the monitoring system or selecting to insert the compensation rod corresponding to the highest rod position value displayed by the first display unit of the monitoring system, the method for determining the balance of the rod and the bar grid by adjusting further includes: and judging whether the compensating rods corresponding to the lowest rod position value/the highest rod position value displayed by the first display unit are consistent with the marks of the compensating rods arranged in the descending order of the rod position values and the rod position values thereof displayed by the second display unit, confirming that the compensating rods corresponding to the lowest rod position value/the highest rod position value displayed by the first display unit are correct when the judging results are consistent, and confirming that the compensating rods corresponding to the lowest rod position value/the highest rod position value displayed by the first display unit are wrong when the judging results are inconsistent. In the embodiment, a measure for confirming whether the result displayed by the first display unit is consistent with the sequencing result displayed by the second display unit is added, so that the safety of the nuclear power plant is improved.
Optionally, after confirming that the compensation rod corresponding to the lowest rod position value/the highest rod position value displayed by the first display unit is correct, and before selecting to lift the compensation rod corresponding to the lowest rod position value displayed by the first display unit of the monitoring system or to insert the compensation rod corresponding to the highest rod position value displayed by the first display unit of the monitoring system downwards, the method for determining rod-and-rod balance adjustment further includes: and checking whether the third display unit has fault alarm display or not, and abandoning the monitoring system for monitoring the rod position of the compensation rod to monitor the rod position of the compensation rod when the checking result shows that the fault alarm display exists.
In this embodiment, if any device of a certain compensation rod fails, the highest-order rod bit value or the lowest-order rod bit value obtained by the monitoring system for rod positions of the compensation rod in embodiment 1 and the sequencing result of the rod bit values are inaccurate, which indicates that the whole monitoring system for rod positions of the compensation rod is invalid. And auditing measures for fault alarm display are added for improving the safety of the nuclear power plant.
