The alarm rule configuration table stores the correspondence between fault rules and fault scenario codes. The alarm rule parameter configuration table stores the correspondence between fault scenario codes and parameter rules. If the electrical parameters are determined to match the first parameter rule, the first fault scenario code is output, which is used to characterize the static fault type of the turnout switch machine.

[0006] According to the fault diagnosis method of the turnout switch machine provided by the present invention, the alarm rule configuration table also stores the correspondence between the type of switch machine, the operation type, the wiring system of the switch machine and the fault scenario code; The determination that there is a first fault rule in the alarm rule configuration table that matches the relevant parameters of the first relay includes: Extract the target type and target track configuration of the turnout switch machine from the equipment data; Search the alarm rule configuration table for the first target fault rule corresponding to the target type, the target operation type, and the target line system; If the parameters related to the first relay match the first target fault rule, the first target fault rule is determined as the first fault rule.

If the electrical correlation curve parameters are determined to match the second parameter rule, the second fault scenario code is output, which is used to characterize the operation fault type of the turnout switch machine.

[0009] According to a fault diagnosis method for a turnout switching machine provided by the present invention, the step of determining that there is a second fault rule in the alarm rule configuration table that matches the relevant parameters of the second relay includes: Search the alarm rule configuration table for the second target fault rule corresponding to the target type, the target operation type, and the target line system; If the parameters related to the second relay match the second target fault rule, the second target fault rule will be determined as the second fault rule.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] Figure 1 This is one of the flowcharts illustrating the fault diagnosis method for a turnout switch machine provided in this embodiment of the invention, such as... Figure 1 As shown, the fault diagnosis method for this turnout switch machine includes the following steps: Step 101: Obtain the equipment data of the turnout switch machine.

[0024] The equipment data includes all data related to the operation of the turnout switch machine.

[0025] For example, when the lower-level machine obtains the equipment data of the turnout switch machine, it sends the equipment data to the Kafka message queue. The Kafka message structure consists of a message header MsgHead and a message body MsgBody. The message header MsgHead includes Line Label, Station Number LocationNo, System Label, etc., and the message body MsgBody includes core fields such as DeviceNo, AlarmLevel, and AlarmStatus. The parsing module consumes equipment data from the Kafka message queue to obtain the equipment data of the turnout switch machine. It then parses the equipment data according to the signal subsystem interface documentation, verifies the validity of the MsgHead fields, extracts information such as DeviceNo and AlarmStatus from the MsgBody, and triggers an alarm for abnormal data (such as missing DeviceNo) to ensure the stability of data transmission and the integrity of fields. Finally, it stores the parsed equipment data of the turnout switch machine in the IoTDB database.

[0026] Step 102: Extract the target operation type of the turnout switch machine from the equipment data.

[0027] For example, when the equipment data is obtained, the target operation type of the turnout switch machine is extracted from the equipment data. If the target operation type is 01, it is determined to be a static type. If the target operation type is 10, it is determined to be a reverse operation type. If the target operation type is 01, it is determined to be a fixed operation type.

[0028] Step 103: If the target operation type is static, extract the first relay related parameters and electrical related parameters of the turnout switch machine from the equipment data.

[0029] For example, when the target operation type is determined to be static, information related to the static type is extracted from the equipment data. Specifically, this may include parameters related to the first relay and electrical parameters. Taking the location of the DBJ relay falling fault as an example, the parameters related to the first relay may include the status of the 1DQJ relay, the status of the DBJ relay, and the status of the FBJ relay. The electrical parameters may include the X2-X4 DC voltage, X2-X4 AC voltage, X1-X2 DC voltage, X1-X2 AC voltage, X1-X4 DC voltage, and X1-X4 AC voltage.

[0030] Step 104: When it is determined that there is a first fault rule in the alarm rule configuration table that matches the relevant parameters of the first relay, determine the first fault scenario code corresponding to the first fault rule.

[0031] The alarm rule configuration table stores the correspondence between fault rules and fault scenario codes. The fault rules in the alarm rule configuration table alarm_rule are fault judgment logic defined based on fault scenarios, and different fault scenarios correspond to different fault rules.

[0032] For example, taking the location of a DBJ drop fault as an example, the first fault rule for the DBJ drop fault scenario stored in the alarm rule configuration table is: 1) Determine that the 1DQJ relay is in a drop state; 2) Determine that the DBJ is in a drop state; 3) Determine that the DBJ is in a drop state and, within a 1-second time range prior to it, the FBJ is continuously in a drop state. Then, the states of the 1DQJ relay, DBJ, and FBJ extracted from the device data are judged. If it is determined that the 1DQJ relay is in a drop state, the DBJ is in a drop state, and, within a 1-second time range prior to it, the FBJ is continuously in a drop state, then it is determined that a first fault rule matching the parameters of the first relay exists in the alarm rule configuration table. Therefore, the first fault scenario code corresponding to the first fault rule is searched in the alarm rule configuration table.

[0033] Step 105: Find the first parameter rule corresponding to the first fault scenario code in the alarm rule parameter configuration table.

[0034] The alarm rule parameter configuration table stores the correspondence between fault scenario codes and parameter rules. The parameter rules in the alarm_degree_param table are rules defined based on fault scenarios, and different fault scenarios correspond to different parameter rules.

[0035] For example, the alarm rule parameter configuration table stores the correspondence between fault scenario codes and parameter rules. Therefore, when the first fault scenario code is obtained, the first parameter rule corresponding to the first fault scenario code can be found in the alarm rule parameter configuration table. Taking the location of the DBJ drop fault as an example, the first parameter rule for the DBJ drop fault scenario stored in the alarm rule parameter configuration table is 50V>X2-X4 DC>30V, 90V>X2-X4 AC>70V, 90V>X1-X2 AC>70V, 50V>X1-X2 DC>30V, 4V>X1-X4 DC, 5V>X1-X4 AC.

[0036] It should be noted that in the correspondence between fault scenario codes and parameter rules, one fault scenario code can correspond to one parameter rule or multiple parameter rules. The specific settings need to be based on the fault scenario. When there are multiple corresponding parameter rules for the first fault scenario code stored in the alarm rule parameter configuration table, there will also be multiple first parameter rules corresponding to the first fault scenario code. This invention does not limit this.

[0037] Step 106: If the electrical related parameters match the first parameter rule, output the first fault scenario code. The first fault scenario code is used to characterize the static fault type of the turnout switch machine.

[0038] For example, the DC voltage of X2-X4, AC voltage of X2-X4, DC voltage of X1-X2, AC voltage of X1-X2, DC voltage of X1-X4, and AC voltage of X1-X4 extracted from the equipment data are judged. If the following conditions are met: 50V > X2-X4 DC > 30V, 90V > X2-X4 AC > 70V, 90V > X1-X2 AC > 70V, 50V > X1-X2 DC > 30V, 4V > X1-X4 DC, and 5V > X1-X4 AC, then it is determined that the electrical related parameters match the first parameter rule. At this time, the first fault scenario code is output. The first fault scenario code is used to characterize the static fault type of the turnout switch machine.

[0039] It should be noted that the fault cause description corresponding to each fault scenario code can also be stored in the alarm rule parameter configuration table. Therefore, when it is determined that the electrical related parameters match the first parameter rule, the fault cause description corresponding to the first fault scenario code can also be output, so that maintenance personnel can know the specific fault cause. This invention does not limit this.

[0040] The fault diagnosis method for a turnout switch machine provided by this invention extracts the target operation type of the turnout switch machine from the equipment data. When the target operation type is static, the method extracts the first relay-related parameters and electrical-related parameters of the turnout switch machine from the equipment data. When it is determined that there is a first fault rule in the alarm rule configuration table that matches the first relay-related parameters, the method determines the first fault scenario code corresponding to the first fault rule. The method then searches for the first parameter rule corresponding to the first fault scenario code in the alarm rule parameter configuration table. When it is determined that the electrical-related parameters match the first parameter rule, the method outputs the first fault scenario code used to characterize the static fault type of the turnout switch machine, thereby realizing automatic fault diagnosis of the turnout switch machine.

[0041] In one embodiment, the alarm rule configuration table also stores the correspondence between the type of switch machine, operation type, wiring system of the switch machine, and fault scenario code; the determination in step 104 above that there exists a first fault rule in the alarm rule configuration table that matches the relevant parameters of the first relay can be achieved in the following way: Extract the target type and target wiring configuration of the turnout switch machine from the equipment data; search the alarm rule configuration table for a first target fault rule corresponding to the target type, the target operation type, and the target wiring configuration; if the parameters related to the first relay match the first target fault rule, determine the first target fault rule as the first fault rule.

[0042] Among them, the track configuration of the turnout switch machine can be L5, L6, L8, etc.

[0043] For example, the alarm rule configuration table pre-stores the correspondence between the type, operation type, wiring system, fault scenario code, and fault rule of the switch machine. When the target type, target wiring system, and target operation type of the turnout switch machine are extracted from the equipment data, the first target fault rule corresponding to the target type, target wiring system, and target operation type can be found in the alarm rule configuration table. The relevant parameters of the first relay are matched with the first target fault rule, without having to match the relevant parameters of the first relay with all the fault rules stored in the alarm rule configuration table. When the relevant parameters of the first relay match the first target fault rule, it means that the first target fault rule is the first fault rule in the alarm rule configuration table that matches the relevant parameters of the first relay. Therefore, the first target fault rule is determined as the first fault rule.

[0044] In this embodiment, the first target fault rule corresponding to the target type, target operation type, and target wiring system is searched in the alarm rule configuration table. If the parameters related to the first relay match the first target fault rule, the first target fault rule is determined as the first fault rule. It is not necessary to match the parameters related to the first relay with all the fault rules stored in the alarm rule configuration table, thereby improving the matching efficiency and further improving the efficiency of static fault diagnosis.

[0045] In one embodiment, the device data includes switching data; the extraction of the first relay-related parameters and electrical-related parameters of the turnout switch machine from the device data in step 103 above can be achieved in the following way: Extract the state of the positioning relay and the state of the reverse position relay from the switch data; when the state of the positioning relay and the state of the reverse position relay are both zero, and the duration of the duration of the state of the positioning relay and the state of the reverse position relay being zero is greater than a first preset duration, and the time difference between any two adjacent switch data in a preset number of switch data is less than a second preset duration, extract the first relay related parameters and electrical related parameters of the turnout switch machine from the equipment data.

[0046] For example, the state of the positioning relay DBJ and the state of the reversing relay FBJ are extracted from the switch data. When both the state of DBJ and the state of FBJ are 0, it indicates that the turnout switch machine is neither in the positioning nor the reversing position and is in an abnormal out-of-position state. It is further determined whether the duration of the DBJ and FBJ states being 0 exceeds the first preset duration (e.g., 5s). If the duration of the DBJ and FBJ states being 0 exceeds the first preset duration, it is further verified whether the time difference between each two adjacent switch data in the preset number of switch data is less than the second preset duration. Taking the preset number of times as 6 and the second preset duration as 5s as an example, if it is determined that the time difference between each two adjacent switch data in the 6 switch data is less than 5s, it is determined that the turnout switch machine has a static fault. At this time, the first relay related parameters and electrical related parameters of the turnout switch machine are extracted from the equipment data.

[0047] It should be noted that when the status of DBJ and FBJ are not 0, it indicates that the turnout switch machine is not in an abnormal out-of-range state, and no further fault diagnosis will be performed at this time.

[0048] In this embodiment, when the state of both the positioning relay and the reverse positioning relay are zero, and the duration of the zero state of both the positioning relay and the reverse positioning relay is greater than a first preset duration, and the time difference between any two adjacent switch data in a preset number of switch data is less than a second preset duration, the relevant parameters of the first relay and the electrical parameters of the turnout switch machine are extracted from the equipment data. Then, the specific static fault type is determined based on the relevant parameters of the first relay and the electrical parameters, avoiding the judgment of the static fault type when no static fault has occurred, and further improving the efficiency of fault diagnosis.

[0049] In one embodiment, Figure 2 This is a second flowchart illustrating the fault diagnosis method for a turnout switch machine provided in this embodiment of the invention. Figure 2 As shown, after step 102 above, the fault diagnosis method for this turnout switch machine further includes the following steps: Step 107: If the target operation type is an action type, extract the second relay related parameters and electrical related curve parameters from the device data.

[0050] Among them, the electrical correlation curve parameters can include voltage correlation curve parameters composed of voltage at different times or current correlation curve parameters composed of current at different times, etc.

[0051] For example, when the target operation type is determined to be an action type, information related to the action type is extracted from the equipment data. Specifically, it may include the second relay related parameters and the electrical related curve parameters. Taking the turnout switch machine fixed operation failure as an example, the second relay related parameters may include the state of DCJ, the state of 1DQJF and the state of BHJ, etc., and the electrical related curve parameters include the A phase current, the B phase current and the C phase current.

[0052] Step 108: When it is determined that there is a second fault rule in the alarm rule configuration table that matches the relevant parameters of the second relay, determine the second fault scenario code corresponding to the second fault rule.

[0053] For example, taking a turnout switch machine's scheduled operation fault as an example, the second fault rule for the turnout switch machine's scheduled operation fault scenario stored in the alarm rule configuration table is: 1) DCJ is in the energized state, 2) 1DQJF is in the energized state, 3) BHJ is in the energized state and then drops, or BHJ is not in the energized state. Then, the states of DCJ, 1DQJF, and BHJ extracted from the equipment data are judged. If it is determined that DCJ is in the energized state, 1DQJF is in the energized state, BHJ is in the energized state and then drops, or BHJ is not in the energized state, then it is determined that there is a second fault rule in the alarm rule configuration table that matches the relevant parameters of the second relay. Therefore, the second fault scenario code corresponding to the second fault rule is searched in the alarm rule configuration table.

[0054] Step 109: If a second parameter rule corresponding to the second fault scenario code is found in the alarm rule parameter configuration table, the electrical correlation curve parameter is matched with the second parameter rule.

[0055] For example, the alarm rule parameter configuration table stores the correspondence between fault scenario codes and parameter rules. Therefore, when a second fault scenario code is obtained, the alarm rule parameter configuration table can be searched to see if a corresponding second parameter rule exists. If no corresponding second parameter rule is found, it means the fault scenario corresponding to the second fault scenario code only needs to be determined based on the relevant parameters of the second relay to determine the action fault type. In this case, the second fault scenario code is directly output, and this code is used to characterize the action fault type of the turnout switch machine. If a corresponding second parameter rule is found in the alarm rule parameter configuration table, it means the fault scenario corresponding to the second fault scenario code needs to be determined based on the relevant parameters of the second relay and the electrical correlation curve parameters to determine the action fault type. Therefore, the electrical correlation curve parameters are further matched with the second parameter rule. Taking the turnout switch machine's scheduled operation failure as an example, the second parameter rule for the turnout switch machine's scheduled operation failure scenario stored in the alarm rule parameter configuration table is: during the time period from when 1DQJF is in the energized state to when 1DQJF is de-energized, determine that the A-phase current is <0.3A, the B-phase current is >1.2A, and the C-phase current is >1.2A.

[0056] It should be noted that in the correspondence between fault scenario codes and parameter rules, one fault scenario code can correspond to one parameter rule or multiple parameter rules. The specific settings need to be based on the fault scenario. When there are multiple corresponding parameter rules for the second fault scenario code stored in the alarm rule parameter configuration table, there will also be multiple second parameter rules corresponding to the second fault scenario code. This invention does not limit this.

[0057] Step 110: If the electrical correlation curve parameters are determined to match the second parameter rules, output the second fault scenario code. The second fault scenario code is used to characterize the action fault type of the turnout switch machine.

[0058] For example, the A-phase current, B-phase current, and C-phase current extracted from the equipment data are judged. If the A-phase current is <0.3A, the B-phase current is >1.2A, and the C-phase current is >1.2A during the time period from when 1DQJF is in the energized state to when 1DQJF is de-energized, then it is determined that the electrical correlation curve parameters match the second parameter rule. At this time, the second fault scenario code is output. The second fault scenario code is used to characterize the static fault type of the turnout switch machine.

[0059] In this embodiment, when the target operation type is dynamic, the second relay-related parameters and electrical correlation curve parameters of the turnout switch machine are extracted from the equipment data. When it is determined that there is a second fault rule in the alarm rule configuration table that matches the second relay-related parameters, the second fault scenario code corresponding to the second fault rule is determined. When the second parameter rule corresponding to the second fault scenario code is found in the alarm rule parameter configuration table, and the electrical correlation curve parameters match the second parameter rule, the second fault scenario code used to characterize the dynamic fault type of the turnout switch machine is output, thereby realizing the automatic operation fault diagnosis of the turnout switch machine.

[0060] In one embodiment, determining in step 108 that a second fault rule matching the parameters of the second relay exists in the alarm rule configuration table can be achieved in the following way: The alarm rule configuration table is searched for a second target fault rule corresponding to the target type, the target operation type, and the target wiring system; if the second relay related parameters match the second target fault rule, the second target fault rule is determined as the second fault rule.

[0061] For example, the alarm rule configuration table pre-stores the correspondence between the type, operation type, wiring system, fault scenario code, and fault rule of the switch machine. When the target type, target wiring system, and target operation type of the turnout switch machine are extracted from the equipment data, the target operation type is the action type. The second target fault rule corresponding to the target type, target wiring system, and target operation type can be found in the alarm rule configuration table. The relevant parameters of the second relay are matched with the second target fault rule, without needing to match the relevant parameters of the second relay with all the fault rules stored in the alarm rule configuration table. When the relevant parameters of the second relay match the second target fault rule, it means that the second target fault rule is the second fault rule in the alarm rule configuration table that matches the relevant parameters of the second relay. Therefore, the second target fault rule is determined as the second fault rule.

[0062] In this embodiment, the second target fault rule corresponding to the target type, target operation type, and target wiring system is searched in the alarm rule configuration table. If the relevant parameters of the second relay match the second target fault rule, the second target fault rule is determined as the second fault rule. It is not necessary to match the relevant parameters of the second relay with all the fault rules stored in the alarm rule configuration table, thereby improving the matching efficiency and further improving the efficiency of action fault diagnosis.

[0063] In one embodiment, the extraction of the second relay-related parameters and electrical correlation curve parameters from the device data in step 107 above can be achieved in the following way: Extract the energizing duration of the permissible operating relay and the gap status of the turnout switch machine from the equipment data; if the target operation type is within the preset operation type range, determine the turnout operation direction based on the target operation type; if the energizing duration of the permissible operating relay is greater than or equal to the energizing duration threshold and the gap status does not match the turnout operation direction, extract the second relay related parameters and the electrical related curve parameters from the equipment data.

[0064] For example, the pull-up duration of the allowable operation relay YCJ of the turnout switch machine and the gap status of the turnout switch machine are extracted from the equipment data. Table 1 shows the correspondence between operation type, turnout direction, whether fault analysis is triggered, and supplementary explanation. When the target operation type is within the preset operation type range of 0x02 to 0x08, fault analysis is triggered. Based on the pre-stored correspondence between operation type and normal turnout direction of the turnout switch machine, the turnout direction of the turnout switch machine corresponding to the target operation type is determined. Taking a pull-up duration threshold of 10s as an example, if the pull-up duration of YCJ is greater than 10s and the gap status of the turnout switch machine does not match the turnout direction of the turnout switch machine, it indicates that the switching process of the turnout switch machine is blocked, and it is determined that the turnout switch machine has a fault. For example, if the obtained gap status is reversed and the turnout direction corresponding to the found target operation type is normalized, then the gap status of the turnout switch machine does not match the turnout direction of the turnout switch machine. At this point, the relevant parameters of the second relay and the electrical correlation curve parameters of the turnout switch machine are extracted from the equipment data.

[0065] Table 1 It should be noted that if the YCJ's lifting time is less than or equal to 10 seconds, or if the gap state of the turnout switch machine matches the turnout switch machine's operating direction, it indicates that the turnout switch machine has not experienced an operational fault, and no further fault diagnosis will be performed in this case.

[0066] In this embodiment, when the allowed operating relay's tethering duration is greater than or equal to the tethering duration threshold and the gap state does not match the operating direction, the relevant parameters of the second relay and the electrical correlation curve parameters are extracted from the equipment data. Then, based on the relevant parameters of the second relay and the electrical correlation curve parameters, the specific action fault type is determined, avoiding the judgment of the action fault type when no action fault has occurred, and further improving the efficiency of action fault diagnosis.

[0067] In one embodiment, the fault diagnosis method for the turnout switch machine further includes the following steps: If a static fault is determined to have occurred in the turnout switch machine, a first alarm message corresponding to the static fault is generated; if an operational fault is determined to have occurred in the turnout switch machine, a second alarm message corresponding to the operational fault is generated; the first alarm message and the second alarm message are stored, and the first alarm message and the second alarm message are sent to the turnout application terminal.

[0068] For example, when a static fault is determined to have occurred in a turnout switch machine, a first alarm message can be generated based on a first fault scenario code, or based on the first fault scenario code and the corresponding fault cause description. The first alarm message can also include the line number, station number, alarm level, and alarm status of the turnout switch machine. Specifically, when a static fault occurs, both the alarm level and alarm status can be set to 1, indicating that the turnout switch machine is currently in an alarm state with an alarm level of 1. If both the alarm level and alarm status are 0, the alarm is considered to have recovered. Finally, the first alarm message is stored in the corresponding log directory. For example, the first alarm message corresponding to a static fault can be stored in the log named "Switch_Rta + station number" under the directory ` / var / local / project / mss-app-bdms300`. Simultaneously, the first alarm message is sent to the turnout application terminal, facilitating maintenance personnel to trace the static fault that occurred in the turnout switch machine based on the logs.

[0069] When a fault is detected in the turnout switch machine, a second alarm message can be generated based on the second fault scenario code, or based on the fault cause description corresponding to the second fault scenario code. The second alarm message can also include the line number, station number, alarm level, and alarm status of the turnout switch machine. When a fault occurs, both the alarm level and alarm status can be set to 1, indicating that the turnout switch machine is currently in an alarm state with an alarm level of 1. If both the alarm level and alarm status are 0, the alarm is considered to have been resolved. Finally, the second alarm message is stored in the corresponding log directory. For example, the second alarm message corresponding to the fault can be stored in the log named "Switch_Ca + station number" under the directory ` / var / local / project / mss-app-bdms300`. Simultaneously, the second alarm message is sent to the turnout application terminal, facilitating maintenance personnel to trace the fault in the turnout switch machine based on the logs.

[0070] It should be noted that the fault diagnosis method for turnout switch machines provided by this invention can be adapted to different types of turnout switch machines. Fault rules and parameter rules corresponding to different types of turnout switch machines can be stored in the alarm rule configuration table and alarm rule parameter configuration table, respectively. For example, the type of turnout switch machine can be ZDJ9, ZD6, etc. It can focus on static and operational anomalies during the operation of the turnout switch machine. Through a closed-loop process of "data acquisition - rule parsing - dual-dimensional diagnosis (static and operational fault diagnosis) - alarm push," accurate fault identification and real-time feedback can be achieved, significantly improving the accuracy of turnout switch machine fault diagnosis, reducing manual inspection costs, and providing support for the stable operation of urban rail transit signaling systems. Furthermore, this invention can achieve both static and operational fault diagnosis, thereby improving the coverage of turnout switch machine diagnosis.

[0071] It should be noted that, in implementing the fault diagnosis method for turnout switch machines provided by this invention, it is necessary to complete the Kafka message queue access, IoTDB database deployment, and diagnostic module (static fault diagnosis / action fault diagnosis) architecture design, develop the data parsing handler, diagnostic logic code, and interface for pushing alarm information to the turnout application terminal; in addition, it is also possible to conduct scenario tests such as static table loss and action timeout to verify the accuracy of alarm information push and log integrity, so as to optimize the configuration of fault rules and parameter rules.

[0072] The fault diagnosis method for turnout switch machines provided by this invention improves the fault diagnosis accuracy to over 98%, covering core faults such as static table malfunction, action timeout, and gap anomalies, while reducing the false alarm rate by 60% (achieved through rule optimization and data verification). The log structure is clear (categorized by static type and action type), and alarm information directly reaches the turnout application end, reducing the fault investigation time for maintenance personnel by 50% and lowering new employee training costs by 40%. It is compatible with ZDJ9, ZD6, and other turnout switch machines, as well as L5, L6, and L8 track systems, supporting the fault diagnosis needs of turnout switch machines in multiple urban rail transit projects. It enables dynamic adaptation of fault scenario coding, fault rules, and parameter rules, and can also update the alarm rule configuration table and alarm rule parameter configuration table based on requirements, reducing the operational complexity for maintenance personnel by 30%.
