Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method for detecting the train overload based on the weight can be applied to an application environment as shown in fig. 1, wherein the application environment comprises a server and a client, and the client communicates with the server through a wired network or a wireless network. Among other things, the client may be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The server can be implemented by an independent server or a server cluster composed of a plurality of servers. The client side is used for collecting the weight of the carriage, and the server side is used for analyzing the weight of the carriage and determining that the target train and/or the target carriage is overloaded.
In an embodiment, as shown in fig. 2, a method for detecting a weight-based train overload is provided, which is described by taking the method as an example of the client in fig. 1, and includes the following steps:
and S10, acquiring the carriage position of the target carriage of the target train.
Specifically, in order to accurately acquire the car position of a target car of a target train, a position detector for detecting the falling of the car is installed on each target car of the target train, the position detector is installed in different car areas for each target car, a client acquires the area position of each car area of the target car by using the position detector, the average value of all the area positions of the target car is determined as the car position of the target car, for example, if the position value of one end of the target car is 5 cm and the position value of the other end of the target car is 7 cm after detection, the average value 6 between 5 and 7 is taken as the car position of the target car.
And S20, acquiring a target resistance corresponding to the carriage position based on the preset position resistance corresponding relation between the carriage position and the resistance.
Specifically, the client obtains a target resistance corresponding to the carriage position based on a position resistance corresponding relationship between a preset carriage position and a resistance in a preset resistance database, for example, if a detector for detecting the carriage slide-down position is a variable resistor, and if the carriage position is 6 cm and the target resistance corresponding to 6 cm is 10 ohms, 10 ohms is obtained based on the position resistance corresponding relationship between the preset carriage position and the resistance.
And S30, acquiring target pressure corresponding to the target resistance as the weight of the carriage based on the preset resistance-pressure corresponding relation between the resistance and the pressure.
Specifically, the client obtains a target pressure corresponding to the target resistance based on a resistance-pressure correspondence between preset resistance and pressure in a preset pressure database, and takes the obtained target pressure as the weight of the carriage.
The target pressure is a pressure to which the floor of the vehicle compartment is subjected, that is, the weight of the vehicle compartment is a load weight excluding the weight of the vehicle compartment itself in an empty state.
And S40, sending the weight of the carriage to a service end, so that the service end can carry out weight analysis processing on the weight of the carriage to obtain a weight analysis result.
Specifically, in order to analyze whether the target train or the target car is overloaded, the car weight obtained in step S30 needs to be sent to the server, and when the server receives the car weight, the server obtains a storage path of the maximum allowable total target weight of the target train in the weight database, and then extracts the total target weight according to the storage path, and obtains a sub-target weight storage path of the maximum allowable load of each target car of the target train in the weight database, and then extracts the sub-target weight according to the storage path. Wherein, the total target weight and the sub-target weight are preset, stored in the weight database and can be called at any time.
For example, the weight database is a MySQL database, the maximum storage path of the total target weight allowed to be borne by the target train is C: \ ProgramFiles \ MySQL \ MySQL Server5.0\ data \ of the target train, firstly, C: \ ProgramFiles \ MySQL \ MySQL Server5.0\ data \ is obtained in the MySQL database, and then the total target weight is extracted according to the C: \ ProgramFiles \ MySQL \ MySQL Server5.0\ data'.
It should be noted that the maximum allowable sub-target weight of each target car in a target train is equal. The weight database may be a MySQL database or an oracle database, and the specific content of the weight database may be set according to the actual application, which is not limited herein.
Further, when the service end obtains the car weight, the total target weight and the sub-target weight, the car weight of each target car is used as the total car weight, then the total car weight and the total target weight are subjected to size analysis and comparison to obtain a total weight analysis result, if the total car weight is larger than the total target weight, the total weight analysis result is determined to be failed, and if the total car weight is smaller than or equal to the total target weight, the total weight analysis result is determined to be passed. Meanwhile, the server side analyzes and compares the weight of each compartment with the weight of the sub-targets to obtain a sub-weight analysis result, if the weight of the compartment is greater than the weight of the sub-targets, the sub-weight analysis result is determined to be failed, and if the weight of the compartment is less than or equal to the weight of the sub-targets, the sub-weight analysis result is determined to be passed.
And S50, if the received weight analysis result sent by the service end is failed, determining that the target train is overloaded.
Specifically, when the server analyzes the total weight analysis result or the sub-weight analysis result, the total weight analysis result or the sub-weight analysis result is sent to the client, and if the total weight analysis result sent by the server received by the client fails, the target train is determined to be overloaded, or if the sub-weight analysis result sent by the server received by the client fails, the target train is determined to be overloaded.
Further, if the total weight analysis result received by the client and sent by the server passes, it is determined that the target train is not overloaded, that is, if the total weight analysis result received by the client and sent by the server passes, it is determined that the target train is empty, full or not full; or if all the sub-weight analysis results received by the client and sent by the server are passed, determining that the target compartment of the target train is not overloaded, that is, if all the sub-weight analysis results received by the client and sent by the server are passed, determining that the target compartment of the target train is empty, full or not full.
Further, after determining that the target car of the target train is overloaded, the method further includes: receiving an overload early warning instruction sent by a server; and outputting overload early warning prompt information based on the overload early warning instruction. For example, when the client receives the overload warning instruction, the client outputs a voice that "the current train is overloaded, the passenger who gets on the train last gets off, waits for the next train, thanks", or outputs "the current train is overloaded, the passenger who gets on the train last gets off, waits for the next train, thanks" through the display screen.
Meanwhile, after the overload early warning prompt information is output based on the overload early warning instruction, the client records the output record of the overload early warning prompt information; sending the output record to a server, when the server receives the output record, performing record analysis processing on the output record to obtain a record analysis result, that is, obtaining a preset target condition, if the output record is in the preset target condition, determining that the record analysis result is passed, if the output record is not in the preset target condition, determining that the record analysis result is failed, and simultaneously sending the record analysis result to a client, if the record analysis result received by the client is passed, returning to the step S10, if the received record analysis result is failed, counting the number of the overloaded target cars, sending the number of the cars to the server, when the server receives the number of the cars, performing number analysis processing on the number of the cars to obtain a number analysis result, that is, judging whether the number of the cars is less than the total number, if the number of the cars is less than the total number, sending a residual compartment identifier filling instruction to the client, and uploading residual compartment identifiers of the residual compartments to the server by the client according to the residual compartment identifier filling instruction when the client receives the residual compartment identifier filling instruction, wherein the residual compartments are compartments except for the overloaded target compartment; determining the difference value between the carriage weight of the overloaded target carriage and the sub-target weight as the overloaded weight by the server, sending a carriage weight allocating instruction, an overloaded carriage identifier and a residual carriage identifier to a carriage weight allocating system by the server, allocating the overloaded weight to the residual carriage with the unique identifier of the residual carriage identifier from the carriage weight of the target carriage with the unique identifier of the overloaded carriage identifier when the carriage weight allocating system receives the carriage weight allocating instruction, the overloaded carriage identifier and the residual carriage identifier, and sending an overload warning relieving instruction to the client; when the client receives the overload early warning removing instruction, the overload early warning removing processing is carried out on the target train based on the overload early warning removing instruction, so that the target carriage is not overloaded, the weight of the target train is balanced, and the safety of the target train is improved.
Further, if the number of the carriages is equal to the total number, determining that the target train is overloaded, and if the number of the carriages is greater than the total number, outputting number error prompt information.
And if the number of the carriages is equal to the total number, determining that the target train is overloaded, and if the number of the carriages is greater than the total number, outputting number error prompt information.
It should be noted that the specific contents of the overload warning prompt message, the overloaded carriage identifier, the remaining carriage identifiers, and the number error prompt message may be set according to practical applications, and are not limited herein.
In the embodiment corresponding to fig. 2, the carriage position of the target carriage of the target train is accurately and quickly acquired, then the target resistance corresponding to the carriage position is quickly acquired, then the target pressure corresponding to the target resistance is quickly acquired as the carriage weight, so that the accurate carriage weight is obtained, then the carriage weight is sent to the service end, so that the service end can perform weight analysis processing on the carriage weight, and thus an accurate weight analysis result is obtained, and finally, if the received weight analysis result sent by the service end is failed, the target train overload is accurately determined, and the monitoring accuracy of the train overload is improved.
