Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that, if directional indications (such as up, down, left, right, front, and back … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indications are changed accordingly.
The intelligent data acquisition system mainly comprises an upper computer and a front end. Front-end refers to independently developed field data collection devices. The operation parameters of the front end and the acquired signals need to interact with an upper computer. Therefore, a set of reliable, mature and easy-to-implement communication protocols is the key for stable operation of the intelligent data acquisition system, wherein the Modbus protocol is a better choice.
The Modbus protocol adopts a master-slave working mode, allows one host device to communicate with a plurality of slave devices, the address of each slave device is set by a user, and the address range is 1-255. The Modbus protocol has the advantages of simple and clear structure, reliable communication and large communication data volume. However, at present, when the master device collects data of the slave devices through the Modbus protocol, data collection must be performed in a polling collection manner of the slave devices, which results in low data collection efficiency.
In view of the above-mentioned defects in the prior art, the present invention provides a method for collecting slave device data in batches, which obtains a set of slave devices by obtaining basic parameters of slave devices to be collected and classifying the slave devices to be collected according to the basic parameters. And then, register address range data corresponding to each slave device in the slave device set is obtained, and hash buckets corresponding to the slave devices are determined according to the register address range data. And finally, acquiring the data stored in the slave equipment to be acquired in batches according to the hash buckets corresponding to the slave equipment respectively. The invention can lead the host equipment to collect the data of the slave equipment in batch, and solves the problem that the host equipment in the prior art has to collect the data in a polling collection mode of the slave equipment, which causes lower data collection efficiency.
As shown in fig. 1, the method comprises the steps of:
step S100, obtaining basic parameters of the slave equipment to be collected, and classifying the slave equipment to be collected according to the basic parameters to obtain a slave equipment set.
Specifically, in order to enable the master device to successfully collect data on the slave devices in batch, in the present embodiment, firstly, the slave devices need to be classified, as shown in fig. 2, a specific classification result is determined according to a basic parameter of each slave device itself, and since the basic parameter of the slave device may reflect some attribute information of the slave device itself, such as address information of the slave device, function information of the slave device, and the like, the present embodiment classifies the slave devices according to the basic parameter of the slave device, and can classify the slave devices having close attributes, so as to realize better batch collection of device data for different types of slave devices in the following process.
In one implementation, the step S100 specifically includes the following steps:
step S101, obtaining basic parameters of the slave equipment to be collected, and determining station address data and functional code data corresponding to the slave equipment to be collected according to the basic parameters;
step S102, all the slave devices to be collected with the same station address data and the same function code data are used as a slave device set.
Specifically, in this embodiment, it is required to obtain basic parameters of the slave device to be acquired, and obtain station address data and function code data in the basic parameters, where the station address data may indicate a base station to which the slave device belongs, and the function code data may reflect a type of a function executed by the slave device to be acquired. In the embodiment, the slave devices with the same station address data and function code data are classified into one slave device set so as to realize the subsequent batch collection of the slave device data which is regularly and sequentially executed.
As shown in fig. 1, the method further comprises the steps of:
step S200, register address range data corresponding to each slave device in the slave device set is obtained, and hash buckets corresponding to each slave device are determined according to the register address range data.
Specifically, after the slave devices to be collected are classified into a plurality of slave device sets, if the batch collection process of the slave device data is directly executed according to the slave device sets, the situation that data collection fails due to the fact that the address range of the slave device register is discontinuous is likely to occur. Therefore, in order to smoothly perform batch collection of data of the slave devices, in this embodiment, register address range data corresponding to each slave device in the slave device set needs to be acquired, hash buckets corresponding to each slave device are determined according to the register address range data, each hash bucket is used as a new batch collection unit, and the data of the slave devices are collected in batches according to the batch collection unit during collection.
In one implementation, the step S200 specifically includes the following steps:
step S201, taking any slave device in the slave device set as a slave device to be processed;
step S202, register address data and register length data of the to-be-processed slave device are obtained, and register address range data corresponding to the to-be-processed slave device are determined according to the register address data and the register length data;
step S203, determining a hash bucket index value corresponding to the slave device to be processed according to the register address range data, and obtaining hash bucket index values corresponding to each slave device in the slave device set;
and step S204, determining the hash bucket corresponding to each slave device according to the hash bucket index value corresponding to each slave device.
It should be noted that, in this embodiment, it is necessary to determine the hash bucket corresponding to each slave device in each slave device set, and since the same determination method is adopted, the embodiment takes one of the slave devices as an example to describe how to determine the hash bucket corresponding to the slave device. Specifically, any one of the slave devices in the slave device set is used as a slave device to be processed, then register address data and register length data of the slave device to be processed are obtained, and register address range data corresponding to the slave device to be processed is determined according to the register address data and the register length data. In an implementation manner, in order to accurately determine register address range data corresponding to the to-be-processed slave device, in this embodiment, the register address data and the register length data are added and then subtracted by 1 to obtain ending address data corresponding to the to-be-processed slave device, and then the register address data is used as start address data, and the register address range data corresponding to the to-be-processed slave device is determined according to the start address data and the ending address data. For example, if the register address data of the to-be-processed slave device a is 24 and the register length data is 8, the corresponding cutoff address data of the to-be-processed slave device a is 24+8-1, which is 31, and the corresponding register address range data is 24-31.
After determining the register address range data corresponding to the to-be-processed slave device, the embodiment needs to further determine the hash bucket index value corresponding to the register address range data corresponding to the to-be-processed slave device according to the register address range data corresponding to the to-be-processed slave device. The hash table is a data structure that is directly accessed based on the key value, and it accesses the record by mapping the key value to a location in the table to speed up the lookup. The hash bucket index value is an index of the hash array, and converts the searched key code value into an index in the hash table through a certain hash algorithm. In an implementation manner, in order to determine the hash bucket index value, in this embodiment, it is necessary to obtain preset maximum batch acquisition register length data, perform integer division on the register address range data of each slave device according to the maximum batch acquisition register length data and perform downward rounding to obtain an integer value, and then determine the hash bucket index value corresponding to each slave device according to the integer value. For example, if the register address range data of the slave device a to be collected is 9 to 12, and the maximum batch collection register length data is 8, the value obtained by dividing 9 by 8 is equal to 1.125, the value obtained by rounding down is 1, the value obtained by dividing 10 by 8 is equal to 1.25, and the value obtained by rounding down is 1, the hash bucket index value corresponding to the slave device a to be collected is 1, and the hash bucket index value corresponds to the hash bucket 1.
As shown in fig. 1, the method further comprises the steps of:
and step S300, acquiring the data stored in the slave equipment to be acquired in batch according to the Hash barrel.
In brief, in this embodiment, it is required to determine hash bucket index values corresponding to all slave devices in each slave device set, and further determine hash buckets corresponding to all slave devices in each slave device set, and perform batch collection of the slave devices by using one hash bucket as a batch collection unit.
In one implementation, the step S300 specifically includes the following steps:
step S301, storing the basic parameters of each slave device into a corresponding hash bucket according to the basic parameters of the slave device to be collected;
step S302, any one of the hash buckets corresponding to the slave devices is used as a batch acquisition unit;
step S303, register address data corresponding to the batch acquisition units are obtained, and target register address data are obtained;
s304, acquiring register length data corresponding to the batch acquisition units to obtain target register length data;
step S305, acquiring station address data corresponding to the batch acquisition unit and functional code data corresponding to the batch acquisition unit to obtain target station address data and target functional code data;
step S306, collecting data stored in the slave device to be collected in batch according to the target register address data, the target register length data, the target station address data and the target function code data.
First, for each slave device set, basic parameters of each slave device in each slave device set need to be stored in its corresponding hash bucket. In the present embodiment, any one of the hash buckets corresponding to each slave device is used as a batch acquisition unit, and it can be understood that each hash bucket is a batch acquisition unit, and the principles of batch acquisition of slave device data are the same.
Firstly, register address data corresponding to one batch acquisition unit is obtained, and target register address data is obtained. Specifically, in this embodiment, the register address data corresponding to the batch acquisition unit is obtained by obtaining the hash bucket index value corresponding to the batch acquisition unit, multiplying the hash bucket index value corresponding to the batch acquisition unit by the maximum batch acquisition register length data, and then taking the register address data corresponding to the batch acquisition unit as the target register address data. For example, assuming that the hash bucket index value corresponding to the batch acquisition unit a is 3 and the maximum batch acquisition register length is 8, the target register address corresponding to the batch acquisition unit a is 3 × 8 — 24.
And then, register length data corresponding to the batch acquisition units are required to be acquired to obtain target register length data. In an implementation manner, the obtained address data of the target register is added to the length data of the maximum batch collection register to obtain a value to be verified. And then, acquiring the maximum register address data of the slave equipment set corresponding to the batch acquisition unit, and comparing the value to be verified with the maximum register address data. Specifically, the maximum register address data of the slave device set corresponding to the batch acquisition unit may be obtained by: register address range data respectively corresponding to each slave device in a slave device set corresponding to the batch acquisition unit is obtained, and according to the register address range data respectively corresponding to each slave device in the slave device set corresponding to the batch acquisition unit, cutoff address data respectively corresponding to each slave device in the slave device set corresponding to the batch acquisition unit is determined, so that cutoff address data to be screened are obtained. And then, the cutoff address data with the largest value in the cutoff address data to be screened is used as the maximum register address data of the slave equipment set corresponding to the batch acquisition unit. For example, if the slave device set B corresponding to the batch collection unit B includes slave devices B1, B2, and B3, where register address ranges of B1, B2, and B3 are 8 to 12, 9 to 15, and 10 to 19, respectively, the respective cut-off address data of B1, B2, and B3 are 12, 15, and 19, respectively, where 19 is the maximum value, and then 19 is used as the maximum register address of the slave device set B.
The value to be verified is then compared to the maximum register address data. And when the value to be verified is less than or equal to the maximum register address data, taking the maximum batch acquisition register length data as the register length data corresponding to the batch acquisition unit. And when the value to be verified is larger than the maximum register address data, subtracting the maximum register address data from the obtained target register address data and adding 1 to obtain the register length data corresponding to the batch acquisition unit. For example, assuming that the target register address data corresponding to the batch acquisition unit a is 24 and the maximum batch acquisition register length is 8, the value to be verified is 24+8 equals 32, and the maximum register address of the slave device set corresponding to the batch acquisition unit a is 30, the register length corresponding to the batch acquisition unit a is 7 according to 30-24+1 equals 7.
And finally, acquiring station address data corresponding to the batch acquisition unit and functional code data corresponding to the batch acquisition unit to obtain target station address data and target functional code data. And then, acquiring data stored in the slave equipment to be acquired in batch according to the target register address data, the target register length data, the target station address data and the target function code data. Specifically, in order to realize batch acquisition of data of the slave devices, in this embodiment, a batch acquisition instruction needs to be generated according to the obtained target register address data, target register length data, target station address data, and target function code data, and then the batch acquisition instruction is used to perform batch acquisition on data stored in the slave devices to be acquired. It can be understood that, in order to perform batch collection on data on all slave devices to be collected, in this embodiment, a batch collection instruction for each hash bucket corresponding to each slave device set needs to be generated, and the batch collection instruction polls data in each hash bucket corresponding to each slave device set in sequence.
