Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

Referring to fig. 1, a method for automatically unhooking a train coupler according to an embodiment of the present invention includes steps S101-S105:

step S101: and detecting the states of the couplers of all the carriages of the train, and acquiring the distance between the carriages when all the couplers are in a locking state.

As a preferred solution of this embodiment, the detecting the states of the couplers of all the carriages of the train, and when all the couplers are in a locked state, obtaining the separation distance between the carriages specifically includes:

The method comprises the steps that state detection is carried out on couplers of all carriages of a train through a coupler state detection encoder, so that the couplers are in an initialized locking state; the state of the coupler comprises a locking state, an unlocking state and a fully-opened state; when the coupler is in a locking state, the distance between the train carriages is measured by the distance radar.

It should be noted that, the present train coupler includes a spiral coupler, an automatic coupler, a tight-lock automatic coupler, a rotary coupler, etc., and the freight train coupler mainly adopts an automatic coupler, which mainly pulls up the coupler lever of the carriage to be pulled up, and then controls the carriage to pull open or collide with another carriage coupler, so that the coupler is pulled up or pulled up.

In the embodiment, the state detection of the couplers of all carriages of the train can be performed by reading the coupler state detection encoder, and the states of the automatic couplers of the carriages comprise a locking state, an unlocking state and a fully-opened state; the locking state is a state that the coupler knuckle of the coupler is blocked by the coupler lock, so that the coupler knuckle cannot rotate outwards to be opened, namely, when every two carriages are connected together, the coupler is in the locking state. The unlocking state is that the lock iron of the coupler lifting rod is lifted, the coupler knuckle can be outwards turned open only by outwards pulling force of two carriages, and the coupler is in a state of exiting, so that when the coupler of one carriage is at the unlocking position during uncoupling, the two carriages connected together can be separated. The fully opened state is a state that the coupler knuckle is completely outwards turned, and when two carriages need to be connected and hooked, the coupler of one carriage is only required to be in the fully opened position, so that the coupler can be hooked after collision with the coupler of the other carriage.

In the preferred embodiment, positioning information of each carriage is obtained by reading an RFID chip of each carriage, and a first detection distance between the carriages is calculated according to the positioning information of each carriage and the length of a preset carriage; when the first detection distance is smaller than the preset compartment distance, detecting the compartment distance through a vehicle-mounted radar among the compartments to obtain a second detection distance; and correcting the second detection distance by combining the positioning information of each carriage, so that the corrected second detection distance is used as the interval between the corresponding carriages.

In this embodiment, the positioning information of each carriage of the train is determined through the RFID chip of each carriage, so that the detected train number and the carriage corresponding to the train can be ensured, and since in the automatic dispatch control system, the coupler hooking of one train is not necessarily controlled in a single thread mode, the accuracy of measuring the inter-carriage distance can be further improved by firstly determining the positioning information of the measured train carriage, the problem that the control error is easy to be caused when the coupler hooking is controlled in a plurality of trains in a multi-thread mode is avoided, and when the first detection distance is smaller than the preset carriage distance, the detected train belongs to the carriage on the same normal running train, the carriage with the distance larger than the preset carriage distance is the carriage with the possibility of identification error, so that the error carriage can be directly rejected and alarmed, and the error carriage can be further detected by staff.

Further, by detecting the carriage with the first detection distance smaller than the preset carriage distance and then detecting the vehicle-mounted radar, the accuracy of carriage distance detection can be improved, namely the distance between the carriages is the real carriage distance, and the measurement reliability and the authenticity are improved.

It can be understood that the couplers of all carriages of the train are determined to be in an initialized state, so that the uniformity of all coupler states in the process of executing automatic coupler uncoupling can be ensured, and further, coupler control errors caused by the non-uniformity of coupler states can be avoided in the process of carrying out automatic coupler control, the occurrence of coupler control errors is reduced, and the accuracy and the efficiency of coupler control are further improved.

Step S102: when the intervals of all the carriages are in a preset interval range, acquiring each carriage number of the train, and determining a trailer carriage to be picked and the number thereof according to a preset carriage scheduling plan of the train, thereby generating a coupler picking request and a trailer hook request; the preset carriage dispatching plan comprises carriage numbers corresponding to the carriages after the carriages are picked up and arranged in the train, and the number of the carriages to be picked up is at least one.

As a preferred solution of this embodiment, when the intervals of all the carriages are within the preset interval range, the numbers of the carriages of the train are obtained, and the trailer carriage to be picked and the number thereof are determined according to the preset carriage scheduling plan of the train, so as to generate a hook picking request and a hook picking request, specifically:

When the intervals of all carriages are in a preset interval range, identifying each carriage number of the train by reading the RFID chip of each carriage of the train, and taking the carriage number as the corresponding carriage number before picking up the trailer carriage; comparing a preset carriage dispatching plan of the train with a carriage number corresponding to the front of the trailer carriage, screening out carriage numbers only existing in the front of the trailer carriage or behind the trailer carriage as the number of the carriage to be picked up, and determining to obtain the trailer carriage to be picked up; when only the number of the compartment before the compartment is picked up exists in the numbers of the compartments to be picked up, a hook picking request is generated, and a trailer hook request filled with blank data is generated; when only the number of the compartment after the compartment is picked up exists in the numbers of the compartment to be picked up, a trailer hook request is generated, and a trailer hook request filled with blank data is generated; and when the numbers of the to-be-picked trailer compartments are all compartment numbers before and after the picking of the trailer compartments, generating a picking hook request and a picking hook request.

In this embodiment, when the intervals of all the carriages are within the preset interval range, that is, the carriages are already in the step of normal unhooking operation, so that the automatic operation step of unhooking the coupler can be directly performed, and the number of each carriage of the train is obtained and combined with the preset train scheduling plan, so that the carriages with different carriage numbers in the preset train scheduling plan are obtained, that is, the carriages are used as the trailer carriage to be unhooked and the number thereof. The preset train dispatching plan is designated or acquired by a vehicle dispatching control center, and can be specifically designed and generated by a computer through a vehicle dispatching algorithm or manual demands.

In the preferred embodiment, when the distance between the carriages exceeds the preset interval range, positioning the adjusted carriages exceeding the preset interval range, and taking all carriages connected with the other end of the adjusted carriages as a readjusted carriage group; generating a displacement signal for controlling the readjustment carriage group according to the spacing of the adjustment carriage so as to enable the readjustment carriage group to move, thereby enabling the spacing of the adjustment carriage to be smaller than a preset spacing range; and re-monitoring the intervals of the carriages in the readjusted carriage group through the vehicle-mounted radar until the intervals of all carriages are controlled to be in a preset interval range.

In this embodiment, when it is detected that the distance between the cars exceeds the interval range of the normal unhooking operation, the distance between the cars exceeding the interval range can be quickly adjusted, and because the cars are connected together through the coupler before the unhooking operation, when the adjusted cars are moved, displacement is generated in all the cars connected to the other end of the adjusted cars, and therefore, the distance between the cars needs to be determined and adjusted again, so that the distance between the cars is prevented from not meeting the requirement of unhooking the coupler.

In this embodiment, only the number of the carriage before the carriage is picked up is existed in the number of the carriage to be picked up, that is, no new carriage is needed to be added, only the original carriage is needed to be removed, which means that the train only needs to be picked up, no trailer hook operation is needed, and in order to control the unified data structure of the message, the trailer hook requests to fill in blank data, thereby avoiding the long analysis time and high error rate of the server caused by the diversity of the message structure.

Further, only the number of the car after the car is picked up is existed in the number of the car to be picked up, namely, the car of the original train is not required to be removed, but a new car is required to be added, which means that the train only needs to carry out the operation of the coupler and does not need to carry out the operation of the coupler, so that the coupler requests to fill blank data.

Step S103: determining a first target carriage from the to-be-picked carriage according to the coupler picking request, and generating a first target coupler list corresponding to the first target carriage, so that unlocking control signals of the first target couplers are sequentially generated according to the first target coupler list, and after all the first target couplers receive the unlocking control signals corresponding to the first target couplers, state detection is carried out on the first target couplers; the first target car list comprises a plurality of first target cars, and the first target car list comprises front and rear first target car couplers to be unhooked, which correspond to the first target cars.

As a preferred solution of this embodiment, according to the request for picking a car, a first target car is determined from the cars to be picked, and a first target car list corresponding to the first target car is generated, so that according to the first target car list, unlocking control signals of the first target car are sequentially generated, and after all the first target car receives the unlocking control signals corresponding to the first target car, state detection is performed on the first target car, which specifically includes:

according to the car picking request, the car number which belongs to the front of the car to be picked is screened from the cars to be picked, so that the first target car is determined; setting all front and rear couplers of the first target carriage as first target couplers, and generating a first target coupler list corresponding to the first target carriage; and sequentially generating unlocking control signals corresponding to the first target couplers according to the first target coupler list, so that after each unlocking control signal is generated, the unlocking control signals are sent to the corresponding first target couplers, the states of the first target couplers are monitored through a coupler state detection encoder, and when the first target couplers are in an unlocking state, the unlocking control signals are generated for the next first target coupler in the first target coupler list until all the first target couplers finish the generation and state detection of the unlocking control signals.

In this embodiment, through the coupler picking request, the car number before the hooked car can be screened from the car to be picked, that is, the car number before the hooked car is the train car that needs to be picked from the original train, so that the train car is used as the first target car, the problem that the control scheme of the existing automatic hooked car is inaccurate in car target control due to simultaneous implementation is avoided, meanwhile, the coupler picking operation is different from the coupler operation of the hook, the number of couplers of the corresponding cars is different, and therefore the message structure for controlling the coupler operation in the prior art is complex, so that the terminal control server is slow in analysis speed, high in error rate and easy to have the problem of data analysis failure. According to the method and the device for controlling the unlocking control signals of the train coupler, the first target carriage and the first target coupler list of the train coupler are directly determined, so that the train terminal control server is small in data processing amount and high in analysis speed, meanwhile, the structure of the control signal messages is uniform, the error rate of data analysis is low, and the accuracy is high.

Further, when the request for the coupler is blank data, it indicates that the first target car and the first target coupler do not exist, and step S104 may be directly performed.

Step S104: when all the first target couplers are in an unlocking state, determining a second target car from the to-be-picked cars according to the trailer coupler request, and generating a second target coupler list corresponding to the second target car, so that full-open control signals of the second target couplers are sequentially generated according to the second target coupler list, and state detection is carried out on the second target couplers after all the first target couplers receive the corresponding full-open control signals; the second target car list comprises a plurality of second target cars, and the second target car list comprises one or two second target car couplers to be unhooked corresponding to each second target car.

As a preferred solution of this embodiment, when all the first target couplers are in an unlocked state, according to the trailer hook request, a second target car is determined from the to-be-picked trailer cars, and a corresponding second target coupler list is generated, which specifically includes:

when all the first target car couplers are in an unlocking state, screening car numbers belonging to the picked cars from the cars to be picked according to the trailer hook request, so as to determine the second target car; sorting the carriage numbers after all the carriages are picked up according to the preset train dispatching plan to obtain a final carriage sorting, and determining a second target coupler corresponding to the second target carriage according to the position of the second target carriage in the final carriage sorting; when the second target carriage is positioned between the two carriages at the final carriage sequencing position, taking the two couplers of the second target carriage as second target couplers; when the second target carriage is at the position of the head and tail of the train at the final carriage sequencing position, the couplers of the second target carriage connected with the rest carriages are used as second target couplers; and generating a second target coupler list according to the second target couplers determined by all the second target carriages.

In this embodiment, when all the first target couplers are in the unlocking state, that is, the coupler hooking operation of the train is completed, the coupler needs to be further controlled to perform the coupler hooking operation, and then the car numbers belonging to the cars after the coupler is hooked are screened out from the cars to be hooked, that is, the car numbers after the coupler is hooked are the train cars which need to be newly added to the original train, so that the train cars are used as second target cars.

Further, since the newly added car is not necessarily at the two ends of the train and may be at the middle of the train, the position of the second target car which needs to be removed in the process of hooking the second target car, and when the hooking operation of the car is performed at the head-tail position of the train, the control operation of the coupler at one side of the second target car is only required; when the hooking operation of the carriage is performed at the middle position of the train, the front and rear hooks of the second target carriage are required to be connected with the carriage, so that the control operation of the couplers at the two sides of the second target carriage is involved. Thus, a second target car may have one or two second target couplers. In this embodiment, through a preset train dispatching plan, the car numbers after all the cars are picked up and hung are sequenced to obtain a final car sequencing, so that the positions and the connection relations between the cars can be quickly generated, and further, the second target couplers corresponding to the second target cars and the number of the second target couplers can be quickly determined.

As a preferred solution of this embodiment, according to the second target coupler list, the full-open control signals of the second target couplers are sequentially generated, so that after all the first target couplers receive the corresponding full-open control signals, state detection is performed on the second target couplers, where the method specifically includes:

In the embodiment, the problem that the control of the carriage target is inaccurate due to simultaneous implementation in the existing control scheme for automatically picking and hanging the carriage is also avoided, so that the structural uniformity of the car coupler control message is ensured, and the accuracy and the efficiency of data analysis are improved.

Further, when the trailer hook request is blank data, it indicates that the second target car and the second target coupler are not present, and step S105 may be directly performed.

Step S105: and after all the second target couplers are in a fully opened state, controlling each trailer carriage to be picked to move, and generating all coupler locking signals after checking the train carriage and the preset carriage scheduling plan, thereby completing automatic picking and hanging of the train couplers.

As a preferred solution of this embodiment, after all the second target couplers are in a fully opened state, each trailer to be picked is controlled to move, and after checking the train carriage and the preset carriage scheduling plan, all the coupler locking signals are generated, so as to complete automatic picking and hanging of the train couplers, which specifically includes:

after all the second target couplers are in a fully-opened state, positioning the position of the carriage to be picked by reading the RFID chip of the carriage to be picked; generating a corresponding control scheduling plan of the carriage to be picked up based on the position of the carriage to be picked up through a train terminal command system; performing movement control on each trailer carriage to be picked according to the control scheduling plan so as to enable each trailer carriage to be picked to move to the connection position corresponding to the train carriage, and positioning the position of the trailer carriage to be picked in real time through an RFID chip of the trailer carriage to be picked; when the position of the trailer carriage to be picked is positioned in real time and is the same as the position of each carriage in the preset carriage scheduling plan, generating an actual carriage sequence after the carriage is currently picked, and carrying out consistency check on the actual carriage sequence and the final carriage sequence; after the consistency check is passed, corresponding locking signals of all the couplers are generated, and state detection is carried out on all the couplers, so that when all the couplers are in a locking state, automatic uncoupling of the couplers of the train is completed.
