[0002] The concrete pump truck currently uses an industrial wireless remote controller for operation control. Due to the interference of interphones, same-frequency remote controllers and the like or internal faults of the remote controller, the remote controller occasionally appears frequency drop phenomenon and cannot continue to operate the pump truck.

[0052] Figure 1 The flowchart of the method for processing frequency drop of the truck-mounted pump truck according to the embodiments of the present application is schematically shown. As shown in Figure 1 The embodiments of the present application provide a method for processing frequency drop of the truck-mounted pump truck, which can include the following steps:

[0053] Step 101, when the frequency drop of the truck-mounted pump truck occurs, it is judged whether the truck-mounted pump truck is successfully reconnected within the first preset time;

[0054] Step 102, in the case that the truck-mounted pump truck is successfully reconnected within the first preset time, it is judged whether the frequency drop times of the truck-mounted pump truck within the single working time exceed the first preset number;

[0055] Step 103, in the case that the frequency drop times of the truck-mounted pump truck within the single working time exceed the first preset number, it is determined that the reason for the frequency drop of the truck-mounted pump truck is strong interference;

[0056] Step 104, in the case that the truck-mounted pump truck fails to reconnect within the first preset time, it is judged whether the frequency drop times of the truck-mounted pump truck exceed the second preset number every interval of the second preset time;

[0057] Step 105, in the case that the frequency drop times of the truck-mounted pump truck exceed the second preset number, it is determined that the reason for the frequency drop of the truck-mounted pump truck is strong interference.

[0058] In the embodiments of the present application, the truck-mounted pump truck refers to a truck-mounted concrete pump, which is installed on a motor vehicle chassis, has a driving function and a concrete pumping function, and is mainly used in the fields of concrete pouring construction of buildings and factories, concrete pouring construction of roads, overpasses and bridges, concrete pouring construction of airports, rail transit and tunnels, etc. The frequency drop refers to a communication terminal. By detecting the frequency drop of the truck-mounted pump truck at the first time, the safety of operation can be improved. The first preset time can refer to a single reconnection safety time. The first preset time is counted by a single working time timer. At the same time, when the truck-mounted pump truck drops frequency, the single working time frequency drop times of the truck-mounted pump truck are increased by 1. The single working time frequency drop times are counted by a single working time frequency drop times counter. By judging whether the truck-mounted pump truck reconnects successfully within the first preset time, the occasional frequency drop event can be handled.

[0059] In the case that the truck-mounted pump truck reconnects successfully within the first preset time, the working state is maintained. The single working time has no fixed value, which refers to the time from the product power-on to the product power-off and stop working. The first preset number refers to the maximum number of frequency drops within the single working time. The first preset number is also not a fixed value, which increases with the increase of working time. In one example, the first preset number increases by 2 times per minute, that is, every 1 minute of the single working time, the first preset number increases by 2 times. In the case that the truck-mounted pump truck reconnects successfully within the first preset time, the truck-mounted pump truck restores communication, and it is also necessary to judge whether the frequency drop times within the single working time exceed the maximum number of frequency drop times within the single working time. By judging whether the frequency drop times within the single working time exceed the maximum number of frequency drop times within the single working time, it can be determined whether the frequency drop is an occasional frequency drop or a fault frequency drop, so as to make further judgment and adjustment to improve the safety of operation.

[0060] Strong interference refers to a fault that causes frequent frequency drop of wireless operation or long time unable to reconnect, for example, line damage, strong magnetic interference, etc. In the case that the frequency drop times of the truck-mounted pump truck within the single working time exceed the first preset number, it means that the frequency drop times within the single working time have exceeded the maximum value allowed by safety. At this time, it is determined that the reason for the frequency drop of the truck-mounted pump truck is strong interference. In one example, the truck-mounted pump truck frequently drops frequency due to line damage.

[0061] In the case that the vehicle-mounted pump truck fails to reconnect within the first preset time, a frequency drop reminder is given on the man-machine interface. The man-machine interface can include, but is not limited to, a display on the vehicle-mounted display, a Bluetooth APP, and a display screen on a wireless remote controller, etc. At the same time, it is determined whether the frequency drop number of the vehicle-mounted pump truck exceeds the second preset number per second preset time interval. The second preset time refers to the frequency drop number rolling statistical time. The second preset time is counted by a frequency drop number rolling statistical time timer. The second preset number refers to the maximum frequency drop number within the frequency drop number rolling statistical time. The second preset number is counted by a frequency drop number counter within the frequency drop number rolling statistical time. The frequency drop number of the vehicle-mounted pump truck is determined whether it exceeds the second preset number per second preset time interval, i.e., the frequency drop number is determined in a loop. In an example, the loop time is 1 minute, and the frequency drop number counter within the frequency drop number rolling statistical time is cleared and starts counting from 0 every 1 minute. When the frequency drop number of the vehicle-mounted pump truck exceeds the second preset number, i.e., the frequency drop number exceeds the maximum safe value within a certain loop time, it is determined that the cause of the frequency drop of the vehicle-mounted pump truck is strong interference. By determining whether the frequency drop number exceeds the maximum safe value within the loop time, it can be determined whether it is a high-frequency drop failure, and the safety and stability of the operation can be compatible.

[0062] Through the above technical solution, when the vehicle-mounted pump truck drops frequency, it is determined whether the vehicle-mounted pump truck reconnects successfully within the first preset time; in the case of successful reconnection, it is determined whether the frequency drop number of the vehicle-mounted pump truck within the single working time exceeds the first preset number; in the case that the frequency drop number of the vehicle-mounted pump truck within the single working time exceeds the first preset number, it is determined that the cause of the frequency drop of the vehicle-mounted pump truck is strong interference; in the case of failed reconnection, the frequency drop number of the vehicle-mounted pump truck is determined whether it exceeds the second preset number per second preset time interval; in the case that the frequency drop number of the vehicle-mounted pump truck exceeds the second preset number, it is determined that the cause of the frequency drop of the vehicle-mounted pump truck is strong interference. Through multi-layer logical judgment, the wireless operation environment of the vehicle-mounted concrete pumping equipment is analyzed in detail, and the occasional frequency drop and the fault frequency drop are dealt with respectively, the safety and the stability of the operation are improved, and the working efficiency of the vehicle-mounted pump truck is improved.

[0063] In the embodiments of the present application, the method can further include:

[0064] In the case that the vehicle-mounted pump truck fails to reconnect within the first preset time, it is determined whether the pumping system is in a working state;

[0065] In the case that the pumping system is in a working state, it is determined whether the vehicle-mounted pump truck reconnects successfully within the third preset time;

[0066] In the case that the vehicle-mounted pump truck fails to reconnect within the third preset time, it is determined that the cause of the frequency drop of the vehicle-mounted pump truck is strong interference.

[0067] Specifically, the working state of the pumping system refers to a pumping state. The third preset time can refer to a reconnect time for maintaining the working state, i.e., a time for maintaining the pumping state to complete the reconnection. The third preset time is timed by a reconnect time timer for maintaining the working state. In the case that the truck-mounted pump truck fails to reconnect within the first preset time, whether the truck-mounted pump truck has dropped frequency more than the second preset number of times is determined every second preset time, and whether the pumping system is in the working state is determined. Whether the working state is determined can be determined by the pumping working pressure, and can also be determined according to information such as the engine speed, the torque, the pumping displacement, the valve power-on state, the switch input signal and the output signal. In the case that the pumping system is in the working state, whether the reconnection is successful within the third preset time is determined. In the case that the reconnection is successful within the third preset time, the pumping state is maintained, the counter is controlled to clear the actual reconnect time for maintaining the working state, and the frequency drop prompt of the man-machine interface is closed. In the case that the reconnection fails within the third preset time, it is determined that the frequency drop of the truck-mounted pump truck is caused by strong interference. By correspondingly adjusting different working states of the pumping device, the stability of the truck-mounted pump truck operation can be improved.

[0068] In the embodiment of the present application, determining whether the pumping system is in the working state can include:

[0069] acquiring the pressure of the pumping system;

[0070] determining whether the pressure of the pumping system is greater than the working pressure of the pumping system;

[0071] In the case that the pressure of the pumping system is greater than the working pressure of the pumping system, it is determined that the pumping system is in the working state.

[0072] Specifically, the working pressure of the pumping system refers to the pressure of the system in the pumping process. The working pressure of the pumping system is generally 3MPa-6MPa. When determining whether the pumping system is in the working state, the pressure of the pumping system can be used for determination. When the pressure of the pumping system is higher than the working pressure of the pumping system, it is determined that the system is in the pumping working state at this time. When the pressure of the pumping system is lower than the working pressure of the pumping system, it is determined that it is in a non-working state at this time. When the pumping system is in a non-working state, the working is prohibited to be started. By determining whether the pressure of the pumping system is greater than the working pressure of the pumping system, whether the pumping system is in the working state can be determined, so as to specify different adjustment strategies according to different working states.

[0073] In the embodiment of the present application, the controller also communicates with the timer and the counter, and the method can further include:

[0074] In a case where the frequency drop times of the truck-mounted pump truck in a single working time do not exceed the first preset number of times, it is determined whether the single working is ended.

[0075] In a case where the single working is ended, the timer and the counter are controlled to be cleared.

[0076] In a case where the single working is not ended, it is continuously determined whether the frequency drop times of the truck-mounted pump truck in the single working time exceed the first preset number of times.

[0077] Specifically, in a case where the frequency drop times of the truck-mounted pump truck in a single working time do not exceed the first preset number of times, it is indicated that the frequency drop times in the single working time are within a safety threshold. The single working time refers to a time from product power-on to product power-off and stop working. At this time, it is determined whether the single working is ended. In a case where the single working is ended, the timer of the single working time and the counter of the frequency drop times in the single working time are controlled to be cleared. And when the next single working starts, the timer and the counter are restarted and counted. In a case where the single working is not ended, it is continuously determined whether the frequency drop times of the truck-mounted pump truck in the single working time exceed the first preset number of times. Until the frequency drop times in the single working time exceed the first preset number of times or the single working is ended. By counting the frequency drop times in the single working time, it can be further determined whether the reason for the frequency drop of the truck-mounted pump truck is strong interference, thereby improving the safety of the working.

[0078] In the embodiment of the present application, the controller communicates with the alarm module, and the method can further include:

[0079] In a case where it is determined that the frequency drop of the truck-mounted pump truck is caused by strong interference, an alarm instruction is sent to the alarm module to control the alarm module to alarm.

[0080] Specifically, the alarm module refers to a module that can perform an alarm operation. The alarm operation performed by the alarm module can include but is not limited to human-computer interaction interface alarm, horn sounding and wireless remote controller vibration. In a case where it is determined that the frequency drop of the truck-mounted pump truck is caused by strong interference, it is indicated that the fault is relatively strong at this time and needs to be detected. Then the controller sends an alarm instruction to the alarm module at this time. The alarm module alarms after receiving the alarm instruction to prompt the operator to troubleshoot the on-site problem.

[0081] In the embodiment of the present application, the controller further communicates with the cloud server, and the method can further include:

[0082] The frequency drop times are uploaded to the cloud server.

[0083] Specifically, the cloud server refers to a basic computing component composed of CPU, memory, operating system and cloud hard disk. It has data storage function. When detecting the frequency drop times in a single working time and the frequency drop times in a rolling statistical time of the frequency drop times, there are timers and counters respectively to record the frequency drop times in a single working time and the frequency drop times in a rolling statistical time of the frequency drop times. After recording the data, the timer and the counter upload the data to the cloud server for storage, so that the operating personnel can analyze the data according to the data stored in the cloud server. In one example, it can be known from the frequency drop times in each interval of the preset time stored in the cloud server that there is a situation of too much frequency drop in a certain morning or afternoon, and whether the frequency drop fault occurs at a fixed time, so as to better determine the fault and make response adjustment. In another example, the frequency drop times in a single working time stored in the cloud server can be combined with the regional difference of the frequency drop fault of the vehicle-mounted pump truck. The remote controller of the vehicle-mounted pump truck frequently appears frequency drop fault, but after checking each hardware and software for many times, the fault is removed after the product is transferred to other places. At this time, the frequency drop times in a single frequency drop time can clearly know the fault characteristics.

[0084] In the embodiment of the present application, when the frequency drop times of the vehicle-mounted pump truck do not exceed the second preset number of times, the frequency drop times rolling statistical time timer continues to count, and at the same time, it is judged whether the frequency drop times in a single working time exceed the first preset number of times. When the frequency drop times of the vehicle-mounted pump truck do not exceed the second preset number of times but exceed the first preset number of times, the instruction corresponding to the first preset number of times is executed preferentially, that is, it is determined that the frequency drop reason of the vehicle-mounted pump truck is strong interference, and an alarm is triggered. When the vehicle-mounted pump truck fails to reconnect within the first preset time, it is judged whether the pumping system is in working state and whether the frequency drop times of the vehicle-mounted pump truck within each interval of the second preset time exceed the second preset number of times. When the vehicle-mounted pump truck reconnects successfully within the third preset time, it is continued to judge whether the frequency drop times in a single working time exceed the first preset number of times. When the vehicle-mounted pump truck reconnects successfully within the third preset time but the frequency drop times in a single working time exceed the first preset number of times, the instruction corresponding to the first preset number of times is executed preferentially. When the vehicle-mounted pump truck reconnects successfully within the third preset time but the frequency drop times of the vehicle-mounted pump truck within each interval of the second preset time exceed the second preset number of times, the instruction corresponding to the second preset number of times is executed preferentially. That is, the instruction corresponding to the first preset number of times is prior to the instruction corresponding to the second preset number of times, and the instruction corresponding to the second preset number of times is prior to the instruction corresponding to the third preset time.

[0085] By the technical scheme, when the frequency drop of the truck-mounted pump truck occurs, it is judged whether the truck-mounted pump truck reconnects successfully within a first preset time; in the case of successful reconnection, it is judged whether the frequency drop times of the truck-mounted pump truck within a single working time exceed a first preset number; in the case that the frequency drop times of the truck-mounted pump truck within the single working time exceed the first preset number, it is determined that the frequency drop reason of the truck-mounted pump truck is strong interference; in the case of failed reconnection, it is judged whether the frequency drop times of the truck-mounted pump truck exceed a second preset number every second preset time; in the case that the frequency drop times of the truck-mounted pump truck exceed the second preset number, it is determined that the frequency drop reason of the truck-mounted pump truck is strong interference. Through the multi-layer logic judgment, the wireless operation environment of the truck-mounted concrete pumping device is analyzed in detail, logic 1 single frequency drop reconnection analysis, logic 2 single working time range analysis, logic 3 fixed cycle analysis, logic 4 reconnection analysis while keeping the working state, which respectively deals with the occasional frequency drop and the fault frequency drop, improves the working efficiency of the truck-mounted pump truck while improving the safety and the stability of the operation.

[0086] Figure 2 A flow chart of a method for processing frequency drop of a truck-mounted pump truck according to an embodiment of the application is schematically shown, as shown in Figure 2 The method for processing frequency drop of a truck-mounted pump truck according to an embodiment of the application can include the following steps:

[0087] S1, the frequency drop occurs, the frequency drop times N within a single working time T1 +1;

[0088] S2, it is judged whether the reconnection is successful within T time (i.e. the first preset time in the application), if yes, go to S3, if no, go to S7 and S14;

[0089] S3, it is judged whether N T1 (i.e. the frequency drop times within the single working time in the application) exceeds a threshold N1 (i.e. the first preset number in the application) within a single working time T1, if yes, go to S4, if no, go to S5;

[0090] S4, it is determined that the frequency drop reason is strong interference, and an alarm is triggered;

[0091] S5, it is judged whether the single working is finished, if yes, go to S6, if no, return to S3;

[0092] S6, T1 is cleared, N T1 is cleared, and the counting is kept;

[0093] S7, it is judged whether the frequency drop times N T2 +1 within T2 time (i.e. the second preset time in the application);

[0094] S8, it is judged whether NT2 If yes, go to S9, if no, go to S10 and S3;

[0095] S9, determine that it is strong interference, stop working immediately, and trigger an alarm;

[0096] S10, continue to count the frequency drop times in the current T2 time;

[0097] S11, determine whether the T2 timing reaches the set value, if yes, go to S12, if no, go to S13;

[0098] S12, restart T2 timing;

[0099] S13, continue T2 timing;

[0100] S14, detect the system pressure;

[0101] S15, determine whether the system pressure is greater than the working pressure P1 (i.e., the working pressure of the pumping system in the present application), if yes, go to S16, if no, go to S19;

[0102] S16, keep working state, and start T3 timing;

[0103] S17, determine whether the reconnection is successful within T3 time, if yes, go to S18 and S3, if no, go to S9;

[0104] S18, keep working state, and clear T3 timing;

[0105] S19, stop working immediately.

[0106] Specifically, when determining that the frequency drop occurs, the frequency drop times N T1 +1 within a single working time are counted. Then, it is determined whether the reconnection is successful within T time (i.e., the first preset time in the present application). In the case of successful reconnection, it is determined whether N T1 (i.e., the frequency drop times within a single working time in the present application) exceeds the threshold N1 (i.e., the first preset number in the present application) within the single working time T1. In the case of exceeding the first preset number, it is determined that the frequency drop of the vehicle-mounted pump truck is caused by strong interference, and the controller sends a control instruction to the alarm module to alarm. In the case of not exceeding the first preset number, it is determined whether the single working is ended. In the case of ending the single working, the single working time and the frequency drop times within the single working time are cleared. And the counting is restarted when the next single working starts. In the case of failed reconnection, the frequency drop times N T2+1. Determine whether the frequency drop times per second preset time interval exceed a second preset number. In the case of exceeding the second preset number, determine that the frequency drop cause of the truck-mounted pump truck is strong interference, immediately stop working, and the controller sends a control instruction to the alarm module to alarm. In the case of not exceeding the second preset number, continue to count the second preset time, and continue to determine N T1 In the case of exceeding the threshold N1 within the single working time T1, determine whether the second preset time reaches a set value. When the set value is reached, the timer is restarted. When the set value is not reached, the timer continues to count. In the case of reconnection failure, the pressure of the pumping system is detected, and it is determined whether the pressure of the pumping system is greater than the working pressure of the pumping system. In the case of the pressure of the pumping system being greater than the working pressure of the pumping system, it indicates that the pumping system is in a working state at this time. It is determined whether the reconnection is successful within the reconnection time of maintaining the working state. If the reconnection is successful, the working state is maintained, and the timer is cleared. If the reconnection is not successful, it is determined that the frequency drop cause of the truck-mounted pump truck is strong interference, and the working is immediately stopped, and the controller sends a control instruction to the alarm module to alarm. In the case of the pressure of the pumping system being less than the working pressure of the pumping system, it indicates that it is not in a working state at this time, and the working is prohibited to be started. Through the multi-dimensional frequency drop analysis of the truck-mounted pump truck when the frequency drops, the occasional frequency drop and the fault frequency drop can be better coped with, the operation experience of the user is improved, and the safety is guaranteed.

[0137] Figure 4 A structural diagram of an apparatus for processing frequency drop of a truck-mounted pump truck according to an embodiment of the application is schematically shown. As shown in Figure 4 The apparatus for processing frequency drop of a truck-mounted pump truck according to an embodiment of the application comprises:

[0138] According to the controller 401 described above;

[0139] The alarm module 402 communicates with the controller 401 and is configured to receive the instruction sent by the controller 401 and alarm.

[0140] Specifically, the alarm module 402 is arranged on the truck-mounted pump truck and is used to receive the instruction sent by the controller 401 and alarm. The alarm module 402 can alarm by sound or light. Therefore, the alarm module 402 can include but is not limited to a truck-mounted siren and an alarm prompt light. In a case that the frequency drop reason of the truck-mounted pump truck is strong interference, the controller 401 sends an alarm instruction to the alarm module 402, and the alarm module 402 receives the alarm instruction sent by the controller 401 and alarms.

[0141] In the embodiment of the application, the apparatus can further comprise:

[0142] a timer 403, in communication with the controller 401, configured to record time data and receive instructions from the controller 401 to clear the data;

[0143] a counter 404, in communication with the controller 401, configured to record the number of frequency drops and receive instructions from the controller 401 to clear the number.

[0144] Specifically, the timer 403 is used to record time data. The timer 403 can include but is not limited to a single working time timer, a frequency drop number rolling statistical time timer, and a keep working state reconnection time timer. The single working time, the rolling number frequency drop statistical time, and the keep working state reconnection time are recorded respectively. The counter 404 is used to record the number of frequency drops. The counter 404 can include but is not limited to a single working time frequency drop number counter and a frequency drop number rolling statistical time frequency drop number counter. The number of frequency drops in the single working time and the number of frequency drops in the rolling statistical time are recorded respectively. At the same time, the timer 403 and the counter 404 also receive instructions from the controller 401 to clear the data. For example, in the case of the end of single working, the controller sends a clear instruction to the timer of the single working time and the counter of the number of frequency drops in the single working time to clear the data.

[0145] In the embodiments of the present application, the device can further include:

When detecting the number of frequency drops in the single working time and the number of frequency drops in the rolling statistical time, the timer 403 and the counter 404 are used to record the number of frequency drops in the single working time and the number of frequency drops in the rolling statistical time respectively. After recording the data, the timer 403 and the counter 404 upload the data to the cloud server 405 for storage, so that the operating personnel can analyze the data according to the data stored in the cloud server 405. In one example, according to the number of frequency drops in each interval of the preset time stored in the cloud server, it can be known that there is a situation of too many frequency drops in a certain morning or afternoon, and whether the frequency drop fault occurs at a fixed time, so as to better determine the fault and make response adjustment. In another example, the number of frequency drops in the single working time stored in the cloud server can be combined with the regional difference of the frequency drop fault of the truck-mounted pump truck. The remote controller of the truck-mounted pump truck frequently appears frequency drop fault, but after checking each hardware and software for many times, the fault is removed after the product is transferred to other places. At this time, according to the number of frequency drops in the single frequency drop time, the fault characteristics can be clearly known.

[0148] By the technical scheme, when the frequency drop of the truck-mounted pump truck occurs, it is judged whether the truck-mounted pump truck reconnects successfully within the first preset time; in the case of successful reconnection, it is judged whether the frequency drop times of the truck-mounted pump truck within the single working time exceed the first preset number; in the case that the frequency drop times of the truck-mounted pump truck within the single working time exceed the first preset number, it is determined that the frequency drop reason of the truck-mounted pump truck is strong interference; in the case of failed reconnection, it is judged whether the frequency drop times of the truck-mounted pump truck exceed the second preset number every second preset time; in the case that the frequency drop times of the truck-mounted pump truck exceed the second preset number, it is determined that the frequency drop reason of the truck-mounted pump truck is strong interference. The wireless operation environment of the truck-mounted concrete pumping device is analyzed in detail through multi-layer logic judgment, and the occasional frequency drop and the fault frequency drop are respectively coped with, so that the safety and the stability of operation are improved, and the working efficiency of the truck-mounted pump truck is improved.
