[0002] The distributed control system (DCS) is the "central nervous system" of the reactor monitoring. It is responsible for collecting and processing the signals from the 0-layer sensors such as the liquid level meter and electromagnetic flow meter and sending them to the host computer. Here, the distributed control system adopts a systematic, modular, and standardized open platform.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0028] At present, in order to ensure the continuous and uninterrupted operation of the distributed control system of the reactor, a large number of distributed control system spare parts are usually stored to replace the faulty DCS components. The distributed control system spare parts usually include distributed control system cards such as analog input cards, switch input cards, analog output cards, switch output cards, main control cards and communication cards. However, since these distributed control system cards as spare parts are only used when the main cards in service fail, it is necessary to store the distributed control system cards as spare parts. However, if these spare parts are not tested and maintained for a long time, it will cause unpredictable failures in the stored distributed control system cards. If the faulty distributed control system cards are applied to the reactor system, it will cause immeasurable losses to the reactor. The traditional storage method of distributed control system cards is limited to cleaning the storage environment of the spare parts of the distributed control system cards, and it is impossible to identify the distributed control system cards that fail during the storage process, and it is impossible to verify the availability of the distributed control system cards in storage.

[0029] In view of the above problems, in one embodiment, Figure 1 As shown, a storage device for distributed control system card components is provided, and the storage device for distributed control system card components applied to a reactor is used as an example for explanation. The storage device for distributed control system card components includes a spare maintenance cabinet 100 and an auxiliary test device 200.

[0030] The auxiliary test equipment 200 is used to simulate the operating environment of the reactor and collect environmental parameters of the operating environment; specifically, the auxiliary test equipment 200 can be composed of stainless steel water storage tanks, stainless steel water storage tanks, electromagnetic flowmeters, regulating valves, pumps, electric heaters, liquid level gauges, thermal resistors, thermocouples, differential pressure transmitters, pressure transmitters, flowmeters, valves, fans, electric control boxes and other components, and is used to simulate the operation of the real reactor, including simulating the process environment of the reactor. The sensors such as liquid level gauges, electromagnetic flowmeters and thermocouples of the auxiliary test equipment 200 can collect physical quantities such as liquid level, electromagnetic flow and temperature in the simulated operating environment based on the sensors when the auxiliary test equipment 200 simulates the operating environment of the reactor, and output sensor output signals corresponding to each physical quantity, and determine the above sensor output signals as environmental parameters.

[0031] Furthermore, the spare parts maintenance cabinet 100 is provided with a main control unit 110 and a plurality of card interfaces 120, each of which is used to connect to a distributed control system card 121. Figure 2 As shown, the card interface 120 is arranged inside the spare parts maintenance cabinet 100. The multiple card interfaces 120 include interfaces for accessing analog input cards, interfaces for accessing switch input cards, interfaces for accessing analog output cards, interfaces for accessing switch output cards, interfaces for accessing master control cards, interfaces for accessing communication cards, and other interfaces. Each distributed control system card can be accessed to the spare parts maintenance cabinet 100 through the card interface 120 to store the distributed control system card. At the same time, in order to meet the requirements of reliability, convenience, maintainability, scalability, diverse functions, and strong adaptability of the storage device of the distributed control system card, the storage device of the distributed control system card is implemented by modular configuration, so as to realize the rapid loading and unloading of the card interface 120, so as to replace other types of card interfaces 120 to adapt to different types of distributed control system cards. Furthermore, the card interface 120 in the spare maintenance cabinet 100 maintains consistency with the hardware platform of the reactor plant control system, that is, all distributed control system cards that can be connected to the reactor plant control system can be connected to the spare maintenance cabinet 100.

[0032] Further, such as Figure 1As shown, the main control unit 110 can be a computer device such as a system controller or a single-chip microcomputer, which is arranged in the spare parts maintenance cabinet 100 and connected to each card interface 120 through a serial communication unit 130. The main control unit 110 is also connected to a switch 150 through an Ethernet communication unit 140 such as a router, so that the main control unit 110 can be connected to a remote host computer (not shown in the figure) through the Ethernet communication unit 140 and the switch 150. Here, the Ethernet communication unit 140 and the switch 150 can be arranged in the spare parts maintenance cabinet 100. Further, the switch 150 can be connected to the host computer through multiple communication lines to establish a communication connection between the main control unit 110 and the host computer. Among them, the host computer can be a computer terminal arranged at a remote control center or other location.

[0033] Furthermore, auxiliary test equipment can be connected to the spare maintenance cabinet, such as Figure 3 As shown, a plurality of quick connection interfaces 123 can be provided on the outer surface of the spare part maintenance cabinet 100, and each quick connection interface 123 is used to receive one or more environmental parameters output by an auxiliary test device (not shown in the figure), such as environmental parameters output by sensors such as a liquid level meter, an electromagnetic flow meter, and a thermocouple. The auxiliary test device can be connected to the quick connection interface 123 via a quick connection cable to input the environmental parameters output by each sensor in the auxiliary test device into the spare part maintenance cabinet 100.

[0034] Further, such as Figure 1 As shown, according to the type of signal connected to the quick connection interface (not shown in the figure), the quick connection interface can be connected to the Ethernet communication unit 140 or the serial communication unit 130 through a cable inside the spare part maintenance cabinet 100, so that the environmental parameters output by the auxiliary test equipment can be transmitted to the Ethernet communication unit 140 or the serial communication unit 130 via the quick connection interface, and then the environmental parameters are sent to the main control unit 110, or output to the distributed control system card 121 via the card interface 120.

[0035] Furthermore, the main control unit 110 is used to perform a status test on the distributed control system card 121 connected to the card interface 120. Here, relevant staff can send a test execution instruction to the main control unit 110 to enable the main control unit 110 to perform a status test on the distributed control system card 121, or set a relevant program in the main control unit 110 to enable the main control unit 110 to perform a status test on the distributed control system card 121 at a preset time interval to determine the card availability status of the distributed control system card 121 and confirm whether the distributed control system card 121 in storage is available.

[0036] Wherein, the state test includes: first, the main control unit 110 controls the auxiliary test device 200 to simulate the operating environment of the reactor and sends the environmental parameters to the distributed control system card 121. Specifically, the main control unit 110 can send an operation instruction to the auxiliary test device 200 to make the auxiliary test device 200 enter the operating state, so that the auxiliary test device 200 simulates the actual reactor operation, including simulating the process environment of the reactor; further, the various sensor devices included in the auxiliary test device 200 can collect physical quantity information such as liquid level, electromagnetic flow and temperature in the simulated operating environment and output sensor output signals, and determine the above sensor output signals as environmental parameters. Further, the auxiliary test device 200 sends the above environmental parameters to the spare parts maintenance cabinet 100, and then sends the environmental parameters to the card interface 120 through the spare parts maintenance cabinet 100, so that the distributed control system card 121 connected to the card interface 120 can receive the above environmental parameters.

[0037] Then, the main control unit 110 controls the distributed control system card 121 to collect parameters of the environmental parameters, obtain parameter collection results, and determine the card availability status of the distributed control system card based on the parameter collection results. Specifically, the main control unit 110 can make the distributed control system card 121 enter the running state, and perform a logic function test on the distributed control system card 121 based on the pre-set logic function test software, including making the distributed control system card 121 process the environmental parameters for parameter collection, and obtain the parameter collection results of the distributed control system card 121 for the environmental parameters. Further, it is judged whether the collection results output by the distributed control system card 121 are accurate to determine the card availability status of the distributed control system card.

[0038] Specifically, the auxiliary test equipment 200 is provided with an environmental sensor (not shown in the figure), which is used to collect the environmental parameters of the simulated operating environment in the reactor and send the environmental parameters to the distributed control system card 121. The environmental sensor may include relevant sensors such as temperature sensors, liquid flow meters, and pressure sensors, and the environmental parameters include relevant parameter information of physical quantities in the reactor such as temperature information, liquid flow information, and pressure information. Here, the installation method, type, and quantity of the environmental sensor and the type and quantity of the environmental parameters are not limited and are also applicable to this embodiment.

[0039] Further, the main control unit 110 controls the distributed control system card 121 to collect parameters of the environmental parameters, obtains parameter collection results, and determines the available state of the card 121 of the distributed control system card based on the parameter collection results, including:

[0040] First, the main control unit 110 controls the distributed control system card 121 to receive the environmental parameters and perform parameter collection on the environmental parameters to obtain the parameter collection results.

[0041] Then, determine the parameter difference between the parameter value of the parameter acquisition result and the preset standard parameter value, and compare the parameter difference with the preset difference threshold. When the parameter difference is less than the preset parameter threshold, determine that the card availability status of the distributed control system card 121 is an available status. When the parameter difference is not less than the preset parameter threshold, determine that the card availability status of the distributed control system card 121 is an unavailable status.

[0042] Among them, the standard parameter value can be the real value of the environmental parameter to be collected by each environmental sensor device included in the auxiliary test device 200. For example, the environmental parameter collected by the thermocouple is the real temperature value of the operating environment simulated by the auxiliary test device 200. Because each simulation work is carried out under control, the real temperature value to be simulated can be predetermined, and the real temperature value is pre-stored in the main control unit 110 as the standard parameter value. Further, for each distributed control system card 121, the real value of the environmental parameter that the distributed control system card 121 can collect parameters can be stored in the main control unit 110 as the standard parameter value corresponding to the distributed control system card 121. When the distributed control system card 121 needs to be tested, the standard parameter value corresponding to the distributed control system card 121 can be obtained to subtract the parameter value of the parameter collection result output by the distributed control system card 121 to obtain the parameter difference.

[0043] Furthermore, the preset difference threshold is used to represent a tolerable error value, and the preset difference threshold can be set for each card 121 of each distributed control system card, and the preset difference threshold corresponding to the card 121 of each distributed control system card is stored locally.

[0044] As an example, if the tested distributed control system card 121 is used to collect the environmental parameters output by the thermocouple and restore the temperature value information in the environmental parameters as the parameter collection result, the main control unit 110 can enable the distributed control system card 121 to process the environmental parameters output by the thermocouple, and receive the temperature value output by the distributed control system card 121, and compare the temperature value with the standard parameter value preset as the actual temperature value of the distributed control system card 121, to determine whether the difference between the temperature value output by the distributed control system card 121 and the actual temperature value exceeds the preset difference threshold. If the numerical difference between the temperature value output by the distributed control system card 121 and the actual temperature value exceeds the preset difference threshold, the card availability status of the distributed control system card 121 is determined to be an unavailable status; conversely, if the numerical difference between the temperature value output by the distributed control system card 121 and the actual temperature value does not exceed the preset difference threshold, the card availability status of the distributed control system card 121 is determined to be an available status.

[0045] Furthermore, for other types of distributed control system card components 121, you can refer to the above-mentioned example, send the environmental parameters required for the distributed control system card component 121 to execute its processing functions, and obtain the parameter collection results output by the distributed control system card component 121, and judge whether the parameter collection results are accurate. When the parameter collection results output by the distributed control system card component 121 are accurate, the card availability status of the distributed control system card component 121 is determined to be an available status; when the error of the parameter collection results output by the distributed control system card component 121 is too large, the card availability status of the distributed control system card component 121 is determined to be an unavailable status.

[0046] Furthermore, when it is tested that the card availability status of a distributed control system card 121 is unavailable, the distributed control system card 121 is identified as an unavailable card, and the main control unit 110 can send an alarm message to the host computer to remind relevant staff that the distributed control system card 121 has an abnormality.

[0047] Furthermore, when it is necessary to debug the instrument sensors, actuator power equipment and other equipment to be debugged in the reactor system, if the above equipment is directly connected to the distributed control system card 121 on the operating reactor system to debug the above equipment, it may affect the operating reactor system. At this time, the instrument sensors, actuator power equipment and other equipment to be debugged can be connected to the distributed control system card 121 on the card interface 120 through hard wiring, and the storage device of the distributed control system card is run to put the distributed control system card 121 into working state, and the instrument sensors, actuator power equipment and other equipment connected to the distributed control system card 121 are debugged, which can improve the debugging efficiency of the instrument sensors, actuator power equipment and other equipment.

[0048] The present embodiment provides a storage device for a distributed control system card. First, multiple distributed control system cards as spare parts can be respectively inserted into the card interface in the storage device of the distributed control system card to store multiple distributed control system cards as spare parts. Further, the main control unit can respond to the test instruction of the distributed control system card, or regularly perform a state test on the distributed control system card stored in the storage device of the distributed control system card. When performing the state test, the main control unit can control the auxiliary test equipment used to simulate the reactor operating environment to run, so that the auxiliary test equipment simulates the operating environment of the real reactor, and the auxiliary test equipment collects the environmental parameters of the operating environment based on the sensors set on the auxiliary test equipment. Further, the main control unit controls the distributed control system card to collect parameters of the environmental parameters, obtains the parameter collection results, and determines the card available state of the distributed control system card based on the parameter collection results, wherein the card available state includes an available state and an unavailable state. The technical solution of the present application can determine whether the distributed control system card in storage is in an available state, thereby realizing the verification of the availability of the distributed control system card in storage.

[0049] In an optional embodiment, the main control unit is used to perform a status test on the distributed control system card connected to the card interface in such a way that the main control unit performs a status test on the distributed control system card connected to the card interface at a preset interval. Specifically, a test time interval can be pre-set at the main control unit, and the main control unit performs a status test on the distributed control system card connected to the card interface at a preset test time interval.

[0050] Furthermore, the main control unit is also used to determine the parameter difference corresponding to the distributed control system card component when performing each status test, and generate a processing accuracy trend chart of the distributed control system card component based on the parameter difference corresponding to the distributed control system card component when performing each status test.

[0051] As an example, if the distributed control system card under test is used to receive the environmental parameters output by the thermocouple in the auxiliary test equipment, and the temperature value of the operating environment collected by the thermocouple is restored in the environmental parameters as the parameter collection result, the value of the temperature value output by the distributed control system card during each state test can be determined as the parameter value. Further, the parameter difference between the parameter value and the standard parameter value corresponding to the distributed control system card is calculated. Specifically, after obtaining the parameter value corresponding to the parameter collection result output by the distributed control system card, the pre-stored standard parameter value corresponding to the distributed control system card is obtained, and the parameter value is subtracted from the standard parameter value to obtain the parameter difference, which can be used as the error value of the collection result of the distributed control system card.

[0052] Furthermore, the main control unit stores the parameter difference corresponding to the distributed control system card component during each state test, and generates a processing accuracy trend graph of the distributed control system card component based on the parameter difference. For example, the main control unit performs a state test on the distributed control system card component once a week, obtains the parameter difference of the distributed control system card component during each state test, processes each parameter difference into a processing accuracy trend graph, and sends the processing accuracy trend graph to a remote host computer, so that relevant staff can view the error value change trend of the distributed control system card component at the host computer, wherein the horizontal axis of the processing accuracy trend graph can be the state tests performed in sequence, and the vertical axis of the processing accuracy trend graph can be the parameter difference. When the error value of the distributed control system card component has a tendency to gradually increase, the distributed control system card component can be determined to be in an unavailable state.

[0053] The embodiments provided in the present application can determine the error change trend of the distributed control system card based on the error value of the distributed control system card obtained each time the distributed control system card is tested, so that relevant personnel can track the error changes of the distributed control system card in storage, thereby improving the functionality of the storage device of the distributed control system card.

[0054] In an optional embodiment, the main control unit is also used to determine the test response time required for the distributed control system card component to output the parameter collection results based on the environmental parameters of the operating environment when performing each status test, and generate a response time trend graph of the distributed control system card component based on the test response time corresponding to the distributed control system card component during each status test.

[0055] Specifically, each time the distributed control system card is tested, the length of time from receiving the environmental parameters to outputting the parameter collection results of the distributed control system card can be recorded as the test response time, and the test response time of each time can be stored. Further, based on the test response time corresponding to the distributed control system card during each state test, a response time trend graph of the distributed control system card is generated, wherein the horizontal axis of the response time trend graph can be the state tests performed in sequence, and the vertical axis of the processing accuracy trend graph can be the test response time.

[0056] Furthermore, after obtaining the response time trend graph, the response time trend graph can be sent to a remote host computer so that relevant staff can determine the response time required for the distributed control system card to process data based on the response time trend graph. When the response time tends to gradually increase, it can be determined that the distributed control system card is in an unavailable state.

[0057] The embodiment provided by the present application can determine the response time change trend of the distributed control system card based on the test response time of the distributed control system card obtained each time the distributed control system card is tested, so that the relevant staff can have a clear understanding of the response time change trend of the distributed control system card in storage, and enrich the functionality of the storage device of the distributed control system card. Furthermore, a spare parts maintenance database can be established based on the processing accuracy trend chart and response time trend chart of each distributed control system card to prompt the management capability of spare parts.

[0058] In an optional embodiment, the main control unit is further used to perform a hardware fault test on the distributed control system card connected to the card interface; and when the test result of the hardware fault test is an abnormal result, a hardware fault alarm signal containing the identification information of the distributed control system card is issued. Here, when the distributed control system card is connected to the card interface, the main control unit can read the identification information of the distributed control system card, wherein the identification information can be the name information of the distributed control system card, the hardware address, and other information that can distinguish the distributed control system card.

[0059] Specifically, the main control unit can be connected to the distributed control system card through the card interface, and the distributed control system card is subjected to a hardware test to determine whether each functional circuit of the distributed control system card is normal. Further, when the test result of the hardware test of the distributed control system card is an abnormal result, it can be determined that the hardware part of the distributed control system card is abnormal, and a hardware fault alarm signal containing the identification information of the distributed control system card is sent to the remote host computer, so that the relevant staff can be informed of the distributed control system card with hardware abnormality in time, and perform corresponding processing. The embodiment provided by the present application can perform a hardware test on the distributed control system card in storage to determine whether the distributed control system card in storage has a hardware abnormality, and send an alarm to the relevant working day personnel in time when the distributed control system card in storage has a hardware abnormality, so that the relevant staff can be informed of the abnormal situation of the distributed control system card in storage in time, and prevent the relevant staff from installing the distributed control system card with hardware abnormality as a spare part in the reactor system, thereby improving the functionality of the storage device of the distributed control system card.

[0060] In an optional embodiment, the card interface is arranged in the spare part maintenance cabinet, and the spare part maintenance cabinet is provided with a temperature and humidity measuring unit and a temperature and humidity control unit, wherein the card interface is pluggable to the spare part maintenance cabinet, and in actual use, the card interface with a different interface type can be replaced for the spare part maintenance cabinet; further, the temperature and humidity control unit in the spare part maintenance cabinet may include a heating device, a refrigeration device, a humidification device and a dehumidification device; further, the temperature and humidity measurement unit is used to collect temperature information and humidity information of the storage space in the spare part maintenance cabinet for storing distributed control system cards.
