Description

The utility model relates to the field of mechanical engineering and can be used in the protection and control systems of lifting machines for recording, processing, accumulating and storing operational and long-term information about the parameters of their work.

From the copyright certificate SU 998309, MPK3 В 66 С 13/16, 02/23/1983, a device for measuring and recording the magnitude and time of operation of a lifting machine (crane) is known, which contains force and angle sensors for the boom, the outputs of which are connected to a summing motor with gearbox, as well as a separate calendar time counter.

The disadvantage of this device is the limited functionality due to the lack of registration of the load on the load gripping body and the position of the load relative to the lifting machine.

More perfect and closest to the proposed one is the registration system of the operating parameters of a lifting machine according to the patent RU 2280609 C2, B 66 C 13/18, G 05 D 9/00, July 27, 2006. It contains load and spatial sensors of the boom equipment of the lifting machine , a microprocessor calculator, a real-time clock, an indication device and a storage device connected to the microprocessor calculator. These sensors are connected to the microprocessor computer directly or through an additional matching device, made in the form of an analog-to-digital converter or interface of a multiplex data exchange channel, and

the microprocessor computer is configured to connect to it an external portable device for reading data from the parameter logger via an electrical connector or a wireless device. The microprocessor computer is configured to overwrite additional data from a portable reader into a memory device or its memory, as well as the ability to change the program of its work in accordance with these additional data.

In this system, all the basic parameters characterizing the load and spatial position of the boom equipment of the lifting machine are recorded, as well as the time of occurrence of critical conditions and the mutual rewriting of information between the portable reader and the storage device, which expands the functionality of the registration system.

The disadvantage of this system is the reduced safety of the lifting machine, due to the lack of control of fuel availability and, accordingly, the possibility of a sudden stop of the engine of the lifting machine during the lifting and moving loads. The operator (operator, crane operator) of the lifting machine, not being able to control the remaining fuel in the fuel tank of the machine, can start another lifting operation with an unacceptably small remaining fuel. In this case, it is possible to suddenly stop the engine and, accordingly, stop the mechanisms of lifting and moving the load in any position, which causes an emergency.

In addition, the inability to control fuel consumption does not allow to identify the deterioration of the technical condition of the machine and, accordingly, to timely carry out the necessary preventive or repair work of the lifting machine, which also leads to a decrease in the safety of its operation.

The technical result, the achievement of which the proposed utility model is aimed at, is to increase work safety

lifting machine by monitoring the availability of fuel and, accordingly, preventing a sudden stop of the engine of the lifting machine during lifting and moving the cargo, as well as by identifying, through an increase in specific fuel consumption, the need for preventive or repair work of the lifting machine, increasing reliability and, accordingly , the safety of her work.

Additional technical results of the utility model are the accounting and rationing of fuel consumption by a lifting machine, as well as the optimization of the time for preventive and repair work based on the results of monitoring the dynamics of changes in fuel consumption.

These technical results are achieved due to the fact that in the registration system of the operating parameters of the hoisting machine, containing the recorder of the operating parameters of the hoisting machine, made autonomous or included in the device or safety system of the hoisting machine, a computer and means for transmitting data about the operating parameters of the hoisting machine from the recorder parameters in the computer, which is configured to process this data, and the parameter logger contains sensors operation parameters load of a machine, a calculator based on a microcontroller with the ability to process the output signals of the sensors of the parameters of the lifting machine, and a storage device connected to the microcontroller, and the sensors of the parameters of the lifting machine are connected to the calculator, which, if necessary, matching the microcontroller with these sensors, made in the form of an analog-to-digital converter, an interface of a multiplex data exchange channel or other interface device, A level or quantity sensor of fuel in the fuel tank of the lifting machine or a fuel consumption sensor by the engine of the lifting machine is introduced, the output of which is connected to a computer that contains, if necessary, an additional matching device for this sensor with a microcontroller, and

the calculator is capable of recording data on the value of the output signals of this sensor in the storage device and / or transmitting them to the computer by means of these means for transmitting data.

These results can also be achieved due to the fact that the means for transmitting data on the operating parameters of the lifting machine from the parameter logger to the computer are made in the form of a portable reader equipped with a non-volatile memory device and devices for matching it with a computer and a computer, or a radio channel, or optical communication channel, or wired cable. These tools can also be made in the form of controllers for a wired or wireless USB interface, the first of which is connected to the calculator of the data logger, and the second is part of the computer. The reader may include a USB interface controller and may be implemented as a Flash USB Drive.

In addition, the means for transmitting data on the operating parameters of the lifting machine from the parameter logger to the computer can be implemented as a controller interface card non-volatile memory, for example Secure Digital Card or Memory Stick connected to the microcontroller of the computer, a reader for this card connected to the computer, and non-volatile memory cards.

To achieve the necessary technical results, the parameter logger may additionally contain a real-time clock and / or controls connected to the microcontroller of the calculator.

These technical results are achieved, in particular, due to the fact that the calculator is configured to further process data on the level or fuel consumption and generate as a result of this processing a warning signal for the driver of the lifting machine to reduce the level or quantity of fuel to a predetermined value, and / or about the excessive consumption of fuel, and / or the need for preventive or repair work of the lifting machine,

or due to the fact that the computer is capable of processing data on the level or consumption of fuel received from the data transmission device, and identifying as a result of this processing an excessive consumption of fuel and / or the need for preventive or repair work of the lifting machine.

The identification of excessive fuel consumption and / or the need for preventive or repair work of the lifting machine can be carried out due to the fact that the calculator or computer is configured to calculate the ratio of fuel consumption over a specified period of time for the lifting machine to the total mass of lifted and moved loads in this period of time and comparing this relationship with a predetermined normative value or by comparing the values of fuel consumption when performing the same type of lifting cycles volume and movement of the cargo and detecting an increase in this flow rate in any cycle in relation to the flow rate in a previously completed cycle.

Thanks to these distinguishing features, the proposed registration system provides:

- timely informing the driver of the lifting machine about the presence (balance) of fuel, allowing the driver to timely refuel it and prevent a sudden stop of the engine and the machine as a whole during lifting and moving loads;

- the formation of warning information signals about a decrease in the level or quantity of fuel to a predetermined minimum acceptable value;

- control, accounting and rationing of fuel consumption;

- optimization of the timing of preventive and repair work of the lifting machine on the basis of identifying the dynamics of changes in fuel consumption and determining the specific fuel consumption for lifting operations.

These signs are in direct causal connection with the achieved technical result and, accordingly, are significant.

These distinctive features in the registration systems of the operating parameters of hoisting machines have not been previously used.

The drawing, as an example of the implementation of the proposed technical solution, presents a functional diagram of a system for recording the parameters of a load-lifting machine with a parameter recorder that is part of the safety system of this machine.

The registration system of the operating parameters of the lifting machine comprises a recorder of operating parameters of the lifting machine 1, a personal computer 2 and means for transmitting data 3 from the parameter logger 1 to the computer 2.

Means for transmitting data 3 about the operating parameters of the lifting machine from the parameter logger to the computer include two wired or wireless data transmitting / receiving devices 4, 5 and, if necessary, a mobile (portable) reading device 6. In particular, transmitting / receiving devices Data 4, 5 can be made in the form of controllers for a wired or wireless interface USB, CAN, LIN, RS-232C, RS-485, Wi-Fi, Bluetooth, ZigBee, GSM, etc., a radio channel (two specialized transceivers) or optical data channel (e.g. x transceivers IrDA). The device for receiving / transmitting data 5 can be made autonomous or included in the computer 2 (the drawing conventionally shows the first option).

Data on the operating parameters of the lifting machine from the parameter logger can be transmitted either directly to the computer 2 or to the reader 6, followed by the transfer of this data from the reader 6 to the computer 2. In the latter case, the reader 6 is connected to the parameter logger 1 ( to device

receive / transmit data 4) and to a computer 2 (to a device for receiving / transmitting data 5).

The reader 6 (if present in the system) contains a non-volatile memory device 7 controller of any wired or wireless interface 8. As it is convenient to use some standard storage device that is identical or structurally compatible with a mobile storage medium of a personal computer, digital video camera etc. In particular, the reader 6 is made in the form of a Flash USB Drive or non-volatile Flash memory card - Secure Digital Card, Memory Stick, etc. Accordingly, data transmitting / receiving devices 4, 5 are made in the form of USB interface controllers or non-volatile memory card interface controllers (card reader). Reader 6 may be called a “parameter recorder reader”, “telemetry information reader”, “black box copyist”, etc., which is not of fundamental importance.

The parameter logger 1, combined with the device or the safety system of the lifting machine, contains load sensors, spatial position, conditions and operating modes of the lifting machine 9, a level sensor, fuel quantity or flow rate 10, a digital or analog-to-digital calculator 11, implemented on the basis of a microcontroller with the ability to process the output signals of the sensors 9 and 10, as well as a storage device 12 connected to the calculator 11.

Sensors 9 generally include a strain gauge load sensor of the load-lifting machine (force or pressure), a sensor for lifting / tilting the boom, sensors for the length of the boom and the angle of rotation of the load-lifting machine (azimuth angle), as well as sensors for wind speed, ultimate lifting of the load-lifting member, proximity to the power line, the provisions of the controls of the lifting machine and other sensors,

the need for installation of which is determined by the design of the lifting machine on which the recorder is installed 1.

The sensor level, quantity or fuel consumption 10 may be capacitive, float, ultrasonic or turbine, installed, respectively, in the fuel tank or in the fuel lines of the lifting machine.

The sensors 9 and 10 are connected to the calculator 11, containing, if necessary, matching device microcontroller with these sensors.

If the sensors 9 and 10 have analog outputs, and the microcontroller of the calculator 11 has a built-in multi-channel analog-to-digital converter, then the sensors 9 and 10 are connected directly to the inputs of the microcontroller of the calculator 11. In this case, if necessary, matching devices can be used - additional amplifiers, level converters signals, as well as circuits or devices for protecting the inputs of the microcontroller from overvoltages in communication lines. In this case, an analog-to-digital computer 11 is used.

If the sensors 9 and 10 are made digital (with digital outputs), then each of these sensors and calculator 11 contain a transceiver, controller, or serial interface driver for a multiplex data transmission channel (CAN, LIN, etc.), which can be autonomous - in the form of an integrated circuit or integrated in the microcontroller of the calculator 11. In this case, the processing of analog signals in the calculator 11 is not performed, i.e. he is digital.

If the calculator 11 has an interface (a data receiving / transmitting device 4) compatible with any standard interface of a personal computer 2, for example, USB, RS-232C, Bluetooth, Wi-Fi, IrDA, etc., then this computer can directly used to read data from the parameter logger 1.

The parameter logger 1 may additionally contain controls 13, made in the form of a set of button keys and designed

to control the operating modes of the registrar and the safety system of the lifting machine, an indication device 14, made, for example, in the form of a set of LEDs and symbolic liquid crystal indicators designed to display the operating modes and / or results of recording the parameters of the lifting machine, as well as a real-time clock 15, made based on a clock microcircuit with an autonomous power source and designed to determine the operating time of a lifting machine and the time of changing its parameters bots when registering these parameters.

The security system of the lifting machine, which includes the parameter logger 1, additionally contains an executive unit 16, made, for example, in the form of a set of power electronic keys, the inputs of which are connected to the outputs of the calculator 11, and the outputs to the actuators of the machine.

Sensors 9 and 10, calculator 11, controls 13, indicators 14, as well as, if necessary, a memory device 12 and a real-time clock 15, in addition to the parameter logger, are simultaneously used when the security system is operating in the mode of load limiting, coordinate protection, etc. P. in accordance with the program of work of the microcontroller of the calculator 11.

The storage device 12 and the non-volatile storage device 7 can be made in the form of flash memory chips. The calculator 11 in addition to the microcontroller additionally contains its power supply circuit, initial start-up, clock generator, input / output overvoltage protection, and other devices functionally necessary in accordance with the used microcontroller switching circuit.

The proposed parameter registration system with a recorder integrated into the safety system of a hoisting machine works as follows.

Before starting the work of the lifting machine, in the memory of the microcontroller of the calculator 11 or in the storage device 12 previously (before the start of the operation of the lifting machine) loads are recorded that are permissible for the various spatial positions of its boom or load-gripping organ. These values are determined, as a rule, by calculation when designing a lifting machine and are presented in the form of its cargo characteristics.

If necessary, the driver, using the controls 13, enters parameters that determine the operating modes of the hoisting machine — the position of the retractable supports, the degree of storage of the sheave, the presence, length and angle of the jib, etc. Similarly, the driver enters the coordinate protection parameters that determine the zone of permissible positions of the lifting (boom) equipment. The parameters entered by the driver are also stored in the storage device 12 or in the memory of the microcontroller of the calculator 11.

During the operation of the lifting machine, the driver acts on the control levers, for example, by hydraulic distributors of the drives of the machine mechanisms, providing lifting operations - raising and lowering the boom, lifting and lowering the load with a winch, turning the platform of the lifting machine, etc.

In this case, the microcontroller of the calculator 11 operates according to the program recorded in its built-in program memory or in the storage device 12 and exchanges information with the sensors 9 and 10 via a common multiplex communication line or receives information from the sensors 9, 10 via separate wires. After receiving information from the sensors 9, the calculator 11 using the mathematical model of the lifting machine determines its current load and the actual position of the lifting equipment. After which, the calculator 11 compares the current position of the lifting equipment (boom or lifting body) with the threshold levels set by the driver when introducing

coordinate protection parameters, as well as comparing the current load with the stored permissible load for the current spatial position of the boom or load-gripping body. Further, depending on the results of this comparison, i.e. when the boom approaches the boundaries of the permitted area of work for coordinate protection or in case the maximum permissible load is exceeded, the calculator 11 generates warning signals received by the indicating device 14 and a shutdown signal of the currently running machine drive, which, through the actuating unit 16, enters the actuating device blocking this movement of the hoisting machine. Due to this, coordinate protection and protection of the lifting machine against overload are carried out.

At the same time, the microcontroller of the calculator 11, working according to the program developed during the design of the registrar of parameters or the security system and previously recorded in the memory of the microcontroller or to the storage device 12, performs primary processing and conversion of the information received from the sensors 9 and 10 in order to prepare the necessary operational data on the load-lifting operation machines for recording in the storage device 12 (in the memory of the registrar). These include, in particular, data on the load on the load-gripping body, on the coordinates of the cargo relative to the load-lifting machine, on the presence and consumption of fuel in the fuel tank of the load-lifting machine, on the control actions of the driver, on the condition and operability of the components and mechanisms of the load-lifting machine, on the operation of restrictions (blocking) of individual movements of the hoisting machine and other indicators provided by the technical specifications for the design of the registrar of parameters. In addition, the microcontroller of the calculator 11 similarly determines the basic information about the work of the lifting machine or its mechanisms for a certain period of its operation, for example, from the moment it is equipped with a recorder. These include the total operating time of the lifting machine, the total number of duty cycles, the total mass of the lifted loads,

characteristic number and other parameter indicators provided by the technical specifications for the design of the parameter registrar.

The indicated parameters are recorded by the microcontroller of the calculator 11 in the storage device 12. At the same time, the date and time of recording the operational parameters are recorded, which are determined using the real-time clock 15, if this clock is in the system. All entries are made repeatedly, for example, periodically. The recording period is selected on the basis of obtaining the necessary information content in the dynamic operating modes of the lifting machine and can be constant or changing depending on the load of the lifting machine and the speed of movement of its boom equipment.

For operational monitoring of the operation of the load-lifting machine, individual results of recording the parameters of the load-lifting machine, including data on fuel consumption, operating hours, characteristic number, etc., are displayed on the display device 14 by commands from the control elements 13.

Before performing each cycle of lifting and moving the load, the driver, focusing on the indications of the indicating device 14, controls the remaining fuel in the fuel tank of the lifting machine. Further, based on the experience of his work, he evaluates the sufficiency of this residue to complete this cycle. Otherwise, the operation of the lifting machine is stopped and refueling is carried out. This eliminates the possibility of a sudden stop of the engine of the lifting machine due to lack of fuel directly in the process of lifting and moving the load and, accordingly, increases the safety of the lifting machine.

In the memory of the microcontroller of the calculator 11 or in the storage device 12 can be pre-recorded the minimum allowable fuel value in the fuel tank of the lifting machine, sufficient to complete the cycle of lifting and moving the load as much as possible

possible duration or the maximum possible energy intensity. In this case, the microcontroller of the calculator 11 compares the current value of the amount of fuel in the fuel tank received from the sensor 10 with the specified minimum acceptable value and, if the current value is reduced to the minimum acceptable, an appropriate warning indication signal is generated for the lifting machine operator. This eliminates the mistakes of the driver in determining the minimum allowable fuel supply and, accordingly, increases the safety of the machine.

Fuel consumption during the operation of a lifting machine depends on its technical condition. Over time, as its components and mechanisms wear out, in particular, the efficiency of the engine, hydraulic pumps and hydraulic motors decreases. This leads to increased fuel consumption.

Therefore, by monitoring the dynamics of changes in fuel consumption, it is possible to assess the technical condition of the lifting machine and, accordingly, to determine or adjust the timing of preventive and repair work of the lifting machine.

To implement this, the microcontroller of the calculator 11, working according to the program, by integrating the current value of fuel consumption (if the sensor 10 is made in the form of a flow sensor) or detecting a decrease in its quantity in the fuel tank (if the sensor 10 is made in the form of a fuel level sensor in the tank), determine the fuel consumption for any pre-installed and recorded in the memory of the microcontroller of the calculator 11 the period of time of operation of the lifting machine, for example, for one shift. Since fuel consumption depends on the load of the lifting machine, the total weight of the lifted and moved loads is calculated over the same period of time. Next, the microcontroller of the calculator 11 calculates the ratio of the magnitude of this fuel consumption to the total mass of lifted and moved loads in this time period and records the value of this

relations in the storage device 12 for its further reading and analysis on a personal computer 2.

At the same time, the previously recorded standard value of this ratio is stored in the memory of the microcontroller of the calculator 11, i.e. standard value of specific fuel consumption. Next, the microcontroller of the calculator 11 compares the current value of this ratio with a predetermined standard value and, if it is exceeded, generates a warning signal to the indicating device 14, informing the driver about the excessive consumption of fuel. For the driver, this is a signal about the improperly selected operating mode of the lifting machine (deviation from the established rules for its operation) or the need for preventive or repair work of this machine. At the same time, all the data obtained is recorded in the storage device 12 for the purpose of subsequent monitoring of the operation of the machine and clarifying the reasons for the excessive consumption of fuel and the need for preventive or repair work by maintenance personnel.

The microcontroller of the calculator 11 can carry out more operational control of the work of the lifting machine by analyzing the fuel consumption in each cycle of lifting and moving the load. For this, the microcontroller, by integrating the current value of fuel consumption or detecting a decrease in its amount in the fuel tank (determining the difference in fuel levels at the beginning and at the end of the working cycle with an appropriate coefficient depending on the configuration of the tank), determines the fuel consumption during each lifting and moving cycle cargo. Next, the microcontroller compares the fuel consumption values in this cycle with the fuel consumption in a similar (same type) load lifting and moving cycle, which this lifting machine previously performed and which data (including fuel consumption in it) are stored in the storage device 12. After that, the microcontroller the calculator 11, in the case of an increase in this flow rate in this cycle in relation to the flow rate in the previously executed

the cycle, in the same way, generates a warning signal indicating the excessive consumption of fuel and / or the need for preventive or repair work of the lifting machine. Moreover, all the data obtained by the microcontroller of the calculator 11 is also recorded in the storage device 12 for subsequent transmission to the computer 2.

If it is necessary to read the recorded data, a reader 6 is connected to the calculator 11 via an electrical connector or a wireless interface. The microcontroller of the calculator 11, in accordance with its program of work, detects the fact of connecting a portable reader 6 and, according to the established standard procedure, via a data receiving / transmitting device 4 (input / output device, controller, transceiver, reader / writer, etc.) and controller 8 overwrites (copies) the data from the memory device 12 into a non-volatile storage device (in Flash memory) 7 of a reader 6. Next, a reader 6 is disconnected from the parameter logger 1 and connected to a personal computer 2 (to a data receiving / transmitting device 5) to transfer (overwrite) data from a non-volatile Flash memory 7 in this computer 2 for secondary processing. These data can also be transmitted to the computer 2 directly from the parameter logger 1 without using a reader 6.

A computer 2, using the secondary data processing algorithms transmitted to this computer, which was previously determined during the development of the parameter registration system and previously stored in its memory, likewise monitors fuel consumption, including detecting a decrease in its remainder of a predetermined value, and monitors the technical condition of the lifting machine through excessive consumption of fuel. Accordingly, the computer 2 identifies the need for preventive or repair work of the lifting machine and generates the necessary warning signals.

Based on the foregoing, the utility model provides increased safety of the hoisting machine by controlling the availability of fuel

and, accordingly, providing the possibility of preventing a sudden stop of the lifting machine during the lifting and moving cargo operation, optimizing the timing of preventive or repair work of the lifting machine, and also allows for accounting and rationing of fuel consumption by the lifting machine.
