Description

TECHNICAL FIELD

[0001] The present application relates to the field of mobile communication, and in particular to a price tag battery voltage acquisition method, device and computer readable storage medium. BACKGROUND

[0002] Electronic price tags are electronic labels that display price information in supermarkets, convenience stores, pharmacies and the like. They are mainly placed on shelves and can replace traditional paper price tags. Each electronic shelf label is connected to a computer database in a shopping mall through a wired or wireless network and displays the latest product prices on the screen of the electronic shelf label.

[0003] In the existing application of electronic price tag technology, the battery voltage of the electronic price tag is collected by an ADC (Analog-to-Digital Converter). However, considering that the ADC accuracy is not high at the present stage and there are large differences in the ADC of each chip, the battery voltage collected by each electronic price tag has poor consistency.

[0005] When the price tag is powered on, collect the battery voltage ten times at intervals and continuously, take the average of the ten battery voltages as the current battery voltage of the price tag, and store the current battery voltage in a first register.

[0006] When the price tag heartbeat wakes up, collect the battery voltage once, and take the average of the battery voltage and the average as the current battery voltage, and store the current battery voltage in a second register.

[0007] Repeat the step of waking up the price tag heartbeat, and in the tenth heartbeat wake-up, store the current battery voltage in ten registers.

[0008] Repeat the step of waking up the price tag heartbeat, and in each heartbeat wake-up after the tenth heartbeat wake-up, reassign the current battery voltage stored in the ten registers in turn, and take the average of the current battery voltage stored in the ten registers after reassignment as the latest battery voltage.

[0011] The above steps are repeatedly performed until ten battery voltages Vbat_vt10, Vbat_vt12…Vbat_vt19 are measured.

[0012] Optionally, when the price tag is powered on, ten battery voltages are collected at intervals and continuously, the average value of the ten battery voltages is taken as the current battery voltage of the price tag, and the current battery voltage is stored in the first register.

[0013] The average value of the ten collected battery voltages Vbat_vt10, Vbat_vt12…Vbat_vt19 is calculated as Vbat_vt1=Vbat_vt1_avg(Vbat_vt10+Vbat_vt12......Vbat_vt19) / 10.

[0070] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present application are proposed.

[0071] Embodiment One

[0072] Figure 3 is a flow chart of the first embodiment of the present application for collecting the voltage of a price tag battery. A method for collecting the voltage of a price tag battery, the method comprising:

[0073] S1, when the price tag is powered on, collect the battery voltage ten times at intervals and continuously, take the average of the ten battery voltages as the current battery voltage of the price tag, and store the current battery voltage in a first register.

[0074] S2, when the price tag is awakened by a heartbeat, collect the battery voltage once, and take the average of the average of the battery voltage and the average as the current battery voltage, and store the current battery voltage in a second register.

[0075] S3, repeat the step of awakening the price tag by a heartbeat, and at the tenth heartbeat, store the current battery voltage in ten registers.

[0076] S4, repeat the step of awakening the price tag by a heartbeat, and at each heartbeat after the tenth heartbeat, reassign the current battery voltage stored in the ten registers in turn, and take the average of the current battery voltage stored in the ten registers after reassignment as the latest battery voltage.

[0077] Optionally, in this embodiment, after the electronic price tag is powered on, the electronic price tag power collection unit delays Tstart to measure the battery voltage 2.94V, and after delaying 10ms, the electronic price tag measures the second battery voltage 2.96, and according to such steps, a total of ten battery voltages Vbat_vt10, Vbat_vt12,..., Vbat_vt19 are measured. Then, the electronic price tag calculates the average of the ten collected battery voltages Vbat_vt10, Vbat_vt12,..., Vbat_vt19, Vbat_vt1 = Vbat_vt1_avg(Vbat_vt10+Vbat_vt12,..., Vbat_vt19) / 10 = 2.95V, this Vbat_vt1 is the initial battery voltage of the electronic price tag when it is powered on, and 2.95V is stored in the register reg1.

[0078] Optionally, in this embodiment, the electronic price tag enters the hibernation state after processing the corresponding business, the electronic price tag hibernation timing module starts to work, and the electronic price tag hibernation timing reaches the hibernation setting threshold 17S. The electronic price tag exits the hibernation and enters the second wake-up state. The electronic price tag power acquisition unit measures the battery voltage 2.97V after a delay of 10ms. The electronic price tag calculates the second wake-up average battery voltage 2.97V of the electronic price tag and the first wake-up battery voltage reg1=2.95V of the electronic price tag. The average battery voltage Vbat_vt2_avg=(reg1+Vbat_vt2) / 2=2.96V is 2.96V, which is the current electronic price tag battery voltage, and 2.97V is stored in the register reg2.

[0079] Optionally, in this embodiment, as described above, when the electronic price tag exits the hibernation and enters the tenth wake-up state, the electronic price tag power acquisition unit measures the battery voltage 2.95V after a delay of 10ms. The electronic price tag calculates the tenth wake-up average battery voltage Vbat_vt1 of the electronic price tag and the first, second,..., ninth wake-up battery voltage reg1, reg2, reg9 of the electronic price tag. The average battery voltage Vbat_vt10_avg=(reg1+reg2+...+2.95) / 10=2.95V is 2.95V, which is the current electronic price tag battery voltage, and 2.95V is stored in the register reg10.

[0080] Optionally, in this embodiment, when the electronic price tag exits the hibernation and enters the eleventh wake-up state, the electronic price tag power acquisition unit measures the battery voltage 2.94V after a delay of Tstart. The electronic price tag reassigns reg1-reg10 and the register, reg1=reg2, reg2=reg3, reg3=reg4, reg4=reg5, reg5=reg6, reg6=reg7, reg7=reg8, reg8=reg9, reg9=2.95V, and reg10=2.94V.

[0081] Optionally, in this embodiment, the electronic price tag then calculates the eleventh wake-up average battery voltage Vbat_vt of the electronic price tag and the average battery voltage Vbat_vt_avg=(reg1+reg2+...+2.94V) / 10=2.95V of the electronic price tag for the previous nine wake-ups. The 2.95V is the current electronic price tag battery voltage.

[0082] It can be seen that in the present embodiment, when the price tag is powered on, the average value of ten consecutive acquisitions is taken as the first battery voltage of this time, and then the battery voltage is acquired once every time the heart wakes up, and the average value of the previous several acquired battery voltages is taken as the current battery voltage, and the actual acquisition of the battery voltage is stored in the corresponding register. When the battery voltage is acquired for the eleventh time and after the eleventh time, the battery voltage acquired by the recent ten heartbeat awakenings is filled into the corresponding ten registers reg1-reg10 to overwrite the previous data. Thus, the electronic price tag battery voltage data is more accurate and smoother, and the accuracy of the price tag battery voltage is improved.
