Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Fig. 1 is a schematic flow chart of a tag data collection method according to an embodiment of the present invention, where the method may be performed by a tag data collection device, the tag data collection device may be implemented in hardware and/or software, and the tag data collection device may be configured in a computer device such as a server. Referring to fig. 1, the method may specifically include the steps of:
S110, acquiring the current power consumption gear and the current transmission speed of the data acquisition equipment.
The data acquisition equipment is wireless equipment integrated with radio frequency identification technology and is used for acquiring commodity information in the signal coverage range of the equipment through the RFID technology, the commodity information is stored in radio frequency tags corresponding to each commodity, so that the acquisition of tag data can be realized through the scanning of the radio frequency tags by the data acquisition equipment, and the acquired tag data is further sent to the mobile terminal to be displayed or stored so as to obtain commodity information of the commodity, and therefore a user can manage the commodity at the mobile terminal conveniently.
The data acquisition device is provided with a power consumption mapping relation table, wherein the power consumption mapping relation table comprises at least one power consumption gear, and one power consumption gear corresponds to one transmission speed interval.
When the radio frequency tag information is acquired through the data acquisition equipment, the acquired radio frequency tag information is subjected to data transmission, and whether the power consumption gear of the current data acquisition equipment is reasonable or not can be judged through the transmission speed. If the current power consumption gear of the data acquisition equipment is higher, the current data acquisition equipment is possibly far away from the mobile terminal, and communication is poor, so that data transmission is slow, and the effective working time of the data acquisition equipment is influenced; if the current power consumption gear of the data acquisition equipment is lower, but the current signal is possibly better, so that a large amount of acquired data cannot be quickly transmitted, the problem that the receiving end (mobile terminal) displays transmission data and is blocked is easily caused, the display time is longer, the label acquisition working cannot be completed on time, and the like is solved. Therefore, the transmission speed of the data acquisition device should correspond to the power consumption gear.
Each power consumption gear corresponds to a transmission speed interval, and the current transmission speed interval can be understood as a maximum value and a minimum value of a corresponding transmission speed when the current power consumption gear is suitable for data transmission. For example, the power consumption mapping relationship table includes three gears, which are A, B, C, respectively, and the three gears are gradually increased, that is, the C gear is the maximum power consumption gear. The transmission speed interval corresponding to each gear may be [ m 0,m1)、[m1,m2 ] and [ m 2, ], and the values of m 0、m1 and m 2 are not limited herein, based on the actual needs of the developer.
Before the radio frequency tag is acquired at the current moment, the current power consumption gear and the current transmission speed of the data acquisition equipment are acquired at first, and the purpose of the method is to judge whether the current transmission speed is matched with a transmission speed interval corresponding to the current power consumption gear.
If the data acquisition equipment is matched with the power consumption gear, the current transmission speed is in a transmission speed interval corresponding to the current power consumption gear, and the power consumption gear adjusting operation is not needed, and the data acquisition equipment continues to acquire the radio frequency tag according to the current power consumption gear.
If the power consumption shift position of the data acquisition equipment is not matched, the current transmission speed is not in the transmission speed interval corresponding to the current power consumption shift position, and the steps S120-S130 are executed.
When judging whether the current transmission speed is matched with the transmission speed interval corresponding to the current power consumption gear, the current transmission speed can be judged once every fixed time period; the data acquisition device may also perform a judgment after each frame of tag data is acquired, and the specific judgment mode is not limited herein.
And S120, when the current transmission speed is not matched with the transmission speed interval corresponding to the current power consumption gear, acquiring the target power consumption gear in the power consumption mapping relation table according to the current transmission speed.
When the current transmission speed is not matched with the transmission speed interval corresponding to the current power consumption gear, the target power consumption gear is required to be obtained in the power consumption mapping relation table according to the current transmission speed, so that the current transmission speed is matched with the power consumption gear. The method has the advantages that the power consumption gear can be dynamically adjusted according to the current transmission speed when the data acquisition equipment acquires the radio frequency tag, so that the working time of the data acquisition equipment is prolonged when the working efficiency is ensured.
S130, acquiring the radio frequency tag according to the target power consumption gear at the current moment to obtain a current tag data set.
The data acquisition equipment can directly acquire radio frequency tags in a signal coverage range, and the number of the radio frequency tags acquired each time can be multiple, so that a current tag data set can be obtained according to the acquired multiple radio frequency tags, and the acquired tag data set can be further sent to the mobile terminal, thereby facilitating the operations of storage or management and the like of the mobile terminal.
The label data acquisition method comprises the steps of firstly, acquiring a current power consumption gear and a current transmission speed of data acquisition equipment; when the current transmission speed is not matched with a transmission speed interval corresponding to the current power consumption gear, acquiring a target power consumption gear in a power consumption mapping relation table according to the current transmission speed; and finally, acquiring the radio frequency tag at the current moment according to the target power consumption gear to obtain a current tag data set. The power consumption gear is set in the data acquisition equipment, and the current transmission speed is compared with the transmission speed interval corresponding to the current power consumption gear, so that whether the data acquisition equipment needs to adjust the power consumption gear is determined, the data acquisition equipment adjusts the target power consumption gear corresponding to the current transmission speed, and the purpose of dynamically adjusting the power consumption of the data acquisition equipment is achieved. When the transmission speed is high, the data acquisition equipment is controlled to be in a high-power-consumption gear, so that the beneficial effect of rapidly acquiring tag data is achieved; when the transmission speed is low, the data acquisition equipment is controlled to be in a low-power-consumption gear, and the beneficial effect of prolonging the working time of the acquisition equipment is achieved.
Fig. 2 is another flow chart of a tag data collection method according to an embodiment of the present invention, where the relationship between the present embodiment and the above embodiment further refines the corresponding features of the above embodiment. As shown in fig. 2, the method may include the steps of:
S210, acquiring the current power consumption gear and the current transmission speed of the data acquisition equipment.
The data acquisition equipment is stored with a power consumption mapping relation table, wherein the power consumption mapping relation table comprises at least one power consumption gear, and one power consumption gear corresponds to one transmission speed interval.
S220, when the current transmission speed is not matched with the transmission speed interval corresponding to the current power consumption gear, acquiring the target power consumption gear in the power consumption mapping relation table according to the current transmission speed.
S230, acquiring standard transmission speed and standard acquisition quantity corresponding to the target power consumption gear.
Because a power consumption gear corresponds to a transmission speed interval, the maximum value and the minimum value in the transmission speed interval have a certain difference, and when data transmission is performed according to the current transmission speed, the data acquisition amount of the data acquisition equipment needs to be considered, if the transmission speed is lower, but the data acquisition amount is higher, the acquired data is easy to cause to be transmitted to the mobile terminal for display, and the problem of blocking exists. Therefore, the current acquisition number adapted to the current transmission speed needs to be further calculated in the target power consumption gear.
When the current acquisition quantity is calculated, the standard transmission speed and the standard acquisition quantity corresponding to the target power consumption gear are preferably acquired, namely, the standard transmission speed and the standard acquisition quantity at the standard transmission speed are defined in each power consumption gear, and the current standard acquisition quantity refers to the quantity of the radio frequency tags acquired by the data acquisition equipment at one time. The purpose of this is to provide a basis for the subsequent calculation of the current acquisition quantity.
S240, obtaining the current collection number according to the standard transmission speed, the standard collection number and the current transmission speed.
An optional implementation manner, obtaining the current collection number according to the standard transmission speed, the standard collection number and the current transmission speed, includes the following steps:
a) And obtaining the change rate of the transmission speed according to the current transmission speed and the standard transmission speed.
Taking the standard transmission speed V 1, the standard collection number N 1 and the current transmission speed V 2 as examples in the target power consumption gear, the transmission speed change rate delta is obtained according to V 1 and V 2 first, and can be expressed as the following relationship:
Δ＝V2/V1 (1)
b) And obtaining the current acquisition quantity according to the product of the transmission speed change rate and the standard acquisition quantity.
Assuming that the current acquisition number is N 2, the following relationship can be expressed in the current step:
N2＝Δ*N1 (2)
If the standard transmission speed V 1 is greater than the current transmission speed V 2, the transmission speed change rate delta is smaller than 1, and the current acquisition number is N 2 which is correspondingly obtained and is smaller than the standard acquisition number and is N 1; if the standard transmission speed V 1 is less than the current transmission speed V 2, the transmission speed change rate delta is greater than 1, and the current acquisition number is N 2 > the standard acquisition number is N 1.
The determining mode of the standard transmission speed and the standard collection number corresponding to each power consumption gear may be that an average speed value and an average collection number corresponding to each power consumption gear; the optimal value of the collection number corresponding to the transmission speed in the current power consumption gear may also be the specific standard transmission speed and the determination mode of the standard collection number are not limited herein, and the actual requirement of the developer is determined.
S250, acquiring radio frequency tags at the current moment according to the target power consumption gear and the current acquisition quantity to obtain a current tag data set.
And S260, packaging the current tag data set and then sending the packaged current tag data set to the mobile terminal.
According to a data transmission protocol, the collected tag data set is generally packaged in a specific data structure, so that data transmission is facilitated. Specifically, the current data structure may be: and the data head, the tag data and the check data encapsulate the acquired tag data set and the current data structure and send the encapsulated tag data set and the current data structure to the mobile terminal.
After receiving the current punctuation data set, the mobile terminal needs to analyze in a specific form, so that the packaged label data set is displayed on the mobile terminal.
The mobile terminal is generally in communication connection with the data acquisition equipment, the current connection mode can be wired connection or wireless connection, and when the mobile terminal is in wired connection, data transmission can be carried out through a serial port communication mode, but the data acquisition equipment is inconvenient to acquire tag data due to the limitation of a data line. When the wireless connection is performed, the data transmission can be performed through the WI-FI module or the bluetooth module, and the connection mode of the specific mobile terminal and the data acquisition device is not limited herein.
When the mobile terminal is in wireless connection with the data acquisition equipment, the interval distance between the mobile terminal and the data acquisition equipment can influence the data transmission speed, and the transmission speed can be reduced along with the increase of the distance. The data acquisition equipment can determine the size of an encapsulation data packet according to the current transmission speed and the current power consumption gear, and the size of the encapsulation data packet can influence the refreshing display effect after the mobile terminal receives the data packet.
The data acquisition method provided by the embodiment of the invention formulates a data transmission strategy at the data acquisition equipment end: defining that when the standard transmission speed is V 1 under the current power consumption gear, each time the package data packet contains N 1 pieces of collected tag data, according to the transmission protocol, the data structure of the package data packet is data head+N 1 pieces of radio frequency tag data+check data, after the mobile terminal receives the current package data, analyzing the current package data packet, namely refreshing N 1 pieces of tag data, and displaying the current tag data set on the mobile terminal; if the current transmission speed is lower than delta times (delta=v 2/V1) of the normal speed, the single package data packet contains delta×n 1 tag data, and according to the transmission protocol, the data structure of the package data packet is data header+delta×n 1 tag data+data check, after receiving the current package data, the mobile terminal analyzes the current package data packet, and can refresh delta×n 1 tag data, and the current tag data set can be displayed on the mobile terminal.
In the above scenario, if the current transmission speed does not correspond to the data collection amount, the current transmission speed is lower, but the data collection amount is larger, for example, due to higher power consumption of the data collection device, after the collected tag data set is packaged, the mobile terminal will wait for a long time to receive the packaged data packet, and when the display interface of the mobile terminal analyzes the packaged data packet to display the tag data set, the mobile terminal will have a click feeling, and will not directly display the tag data set completely. According to the label data acquisition method provided by the embodiment of the invention, the steps S210 to S250 are repeated all the time in the transmission process, so that the current transmission speed, the power consumption gear of the acquisition equipment and the current data acquisition amount are corresponding, the effect of smooth display can be achieved after the acquired current label data set is transmitted to the mobile terminal, and the display interface can not feel tired. By the current mode, the beneficial effect of reducing the refreshing waiting time of the display interface of the mobile terminal is achieved on the premise of dynamically adjusting the power consumption of the data acquisition equipment.
Referring to fig. 3, fig. 3 is a schematic flow chart of a tag data collection method according to an embodiment of the invention. The present embodiment is related operation steps of the previous embodiment in the mobile terminal. Specifically, after the mobile terminal receives the current tag data set, the following operation steps are performed:
S310, analyzing the current tag data set.
The mobile terminal may analyze the current tag data set in such a manner that after receiving the package data packet, the mobile terminal first completes verification in a specific manner, and then obtains the current tag data set in the package data packet, so as to analyze a plurality of tag data included in the current tag data set.
S320, comparing the current tag data set with the last tag data set to obtain the data repetition rate.
The last tag data set is the tag data set sent by the data acquisition equipment, which is received and analyzed by the mobile terminal at the last moment.
The purpose of obtaining the data repetition rate of the current tag data set and the last tag data set is to know the condition of the radio frequency tag acquired by the current data acquisition equipment on site, if the data repetition rate is too high, the effective moving range of the current data acquisition equipment when acquiring the radio frequency tag on site is smaller, but the data repetition rate acquired twice may be too high due to the reasons that the radio frequency tag of the commodity is blocked and the like; if the data repetition rate is extremely low, there may be a case where the radio frequency tag is not completely acquired.
S330, obtaining a power consumption gear control instruction according to the data repetition rate and a transmission speed interval of the current transmission speed corresponding to the current power consumption gear.
The mobile terminal sends the obtained power consumption gear control instruction to the data acquisition equipment so that the data acquisition equipment can realize data acquisition operation according to the current power consumption gear control instruction
Optionally, in the data acquisition method provided by the embodiment of the present invention, the power consumption gear control instruction includes a power consumption gear lowering instruction and a power consumption gear raising instruction.
