Description

TECHNICAL FIELD

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

[0002] Electronic Shelf Label (ESL) is used to replace the traditional paper price tag and has become a trend. It has become a standard in the new retail industry, and some large supermarkets have used electronic price tags. The use of electronic price tags improves the work efficiency of the store, frees the hands of employees, and can save a lot of manpower and time cost for the merchant in the long run.

[0003] With the upgrading needs of supermarket system management, shelf labels gradually introduce electronic price tags to facilitate label changes and replacements in supermarket and other selling markets. At present, electronic price tags are basically battery-powered, and different specifications and quantities of batteries are configured according to size and business complexity. The service life of the battery is limited, and reducing power consumption and prolonging the service life are the functional points that every manufacturer must consider. The working power of the price tag is the key factor to determine the power consumption. High power consumption and fast power consumption can quickly and stably receive and send information, but the signal is strong. Reducing power consumption can save power, but the signal is weak, which is easy to fail to receive. At the same time, the power size is also related to the limited coverage radius of the price tag, involving the number of base stations used and the push map success rate.

[0004] As can be seen, in the prior art, it is difficult to develop a unified or appropriate power scheme for electronic price tags due to various factors. SUMMARY

[0005] In order to solve the above technical defects in the prior art, the present application provides a price tag power dynamic regulation method, which comprises:

[0006] In the idle state, the transmit power of the price tag is gradually reduced, and the received signal value when entering the same base station is recorded.

[0007] The lowest transmit power when failing to enter the network to the base station and the corresponding lowest receive signal value are recorded, and the minimum unit incremental value of the lowest transmit power is used as the transmit power threshold of the price tag, and the lowest receive signal value is used as the comparison threshold of the signal test value.

[0008] When the price tag is in the network state, the receive signal value of the price tag is monitored.

[0009] If the received signal value is greater than the comparison threshold, the current transmission power is decreased by the minimum unit step by step until the received signal value is in the proximity of the comparison threshold, and if the received signal value is less than the comparison threshold, the current transmission power is increased by the minimum unit step by step until the received signal value is in the proximity.

[0010] Optionally, the step of decreasing the transmission power of the price tag step by step in the idle state and recording the received signal value when entering the same base station each time comprises:

[0011] When the price tag is powered on, if a push image task is not received within a first preset time, it is determined that the price tag enters the idle state.

[0012] In the idle state, information is transmitted at the maximum transmission power, and after a base station with the highest signal strength is searched for, the price tag enters the network.

[0013] Optionally, the step of decreasing the transmission power of the price tag step by step in the idle state and recording the received signal value when entering the same base station each time further comprises:

[0014] When the base station with the highest signal strength is successfully entered, the base station and the current received signal value are recorded.

[0015] The transmission power of the price tag is decreased step by step by the minimum unit based on the maximum transmission power.

[0016] Optionally, the step of decreasing the transmission power of the price tag step by step in the idle state and recording the received signal value when entering the same base station each time further comprises:

[0017] After the transmission power is decreased each time, the searching for and entering of the base station are re-executed.

[0018] When the base station is successfully entered, the current transmission power and the current received signal value are recorded, and a correspondence between the current transmission power and the current received signal value is established.

[0019] Optionally, the step of decreasing the transmission power of the price tag step by step in the idle state and recording the received signal value when entering the same base station each time further comprises:

[0020] When the base station is first entered unsuccessfully, the entering of the base station is repeatedly executed with the same transmission power within a second preset time.

[0021] If the base station cannot be successfully entered within the second preset time, the current transmission power is determined to be the lowest transmission power when the base station cannot be entered.

[0022] Optionally, the record is unable to access the minimum transmit power of the base station and the corresponding minimum receive signal value, and the minimum unit increment value of the minimum transmit power is taken as the transmit power threshold of the price tag, and the minimum receive signal value is taken as the comparison threshold of the signal test value, comprising:

[0023] The minimum unit increment value of the minimum transmit power is taken as the transmit power threshold of the price tag.

[0024] According to the corresponding relationship, the receive signal value corresponding to the transmit power threshold is determined as the comparison threshold of the signal test value.

[0025] Optionally, when the price tag is in the network access state, the receive signal value of the price tag is monitored, comprising:

[0026] The replacement of the base station in the network access state is monitored.

[0027] If the price tag is replaced to a new base station, the transmit power threshold and the comparison threshold corresponding to the new base station are determined in the idle state.

[0028] Optionally, when the price tag is in the network access state, the receive signal value of the price tag is monitored, comprising:

[0029] The replacement of the channel connected to the base station in the network access state is monitored.

[0030] If the price tag is replaced to a new channel, the transmit power threshold and the comparison threshold corresponding to the new channel are determined in the idle state.

[0031] The present application also proposes a price tag power dynamic regulation device, which comprises a memory, a processor and a computer program stored in the memory and executable on the processor, and the computer program realizes the steps of the price tag power dynamic regulation method according to any one of the above when executed by the processor.

[0032] The present application also proposes a computer readable storage medium, which stores a price tag power dynamic regulation program, and the price tag power dynamic regulation program realizes the steps of the price tag power dynamic regulation method according to any one of the above when executed by the processor.

[0033] The tag power dynamic regulation method, device and computer readable storage medium of the present application are characterized in that: in an idle state, the transmitting power of the tag is gradually reduced, and the received signal value when entering the same base station is recorded; the lowest transmitting power when failing to enter the base station and the corresponding lowest received signal value are recorded, and the minimum unit incremental value of the lowest transmitting power is used as the transmitting power threshold of the tag, and the lowest received signal value is used as the comparison threshold of the signal test value; when the tag is in an entering state, the received signal value of the tag is monitored; if the received signal value is greater than the comparison threshold, the minimum unit is gradually reduced from the current transmitting power until the received signal value is in the adjacent range of the comparison threshold, and if the received signal value is less than the comparison threshold, the minimum unit is gradually increased from the current transmitting power until the received signal value is in the adjacent range. An efficient and flexible tag power dynamic regulation scheme is realized, which greatly reduces the power consumption of the tag under the premise of ensuring the normal operation of the tag, effectively delays the battery life of the tag, and significantly improves the product competitiveness of the tag.

[0070] Although the above describes the LTE system as an example, those skilled in the art should know that the present application is not only applicable to the LTE system, but also applicable to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems, etc., which are not limited here.

[0071] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the method of the present application are proposed.

[0072] Embodiment one

[0073] Figure 3 is a flow chart of the first embodiment of the tag power dynamic regulation method. A tag power dynamic regulation method, the method comprising:

[0074] S1, in the idle state, the transmitting power of the tag is gradually reduced, and the received signal value when entering the network successively is recorded.

[0075] S2, the lowest transmitting power when failing to enter the network to the base station and the corresponding lowest received signal value are recorded, and the minimum unit incremental value of the lowest transmitting power is taken as the transmitting power threshold of the tag, and the lowest received signal value is taken as the comparison threshold of the signal test value.

[0076] S3, when the tag is in the network entry state, the received signal value of the tag is monitored.

[0077] S4, if the received signal value is greater than the comparison threshold, the current transmitting power is gradually decreased by the minimum unit until the received signal value is in the adjacent range of the comparison threshold, and if the received signal value is less than the comparison threshold, the current transmitting power is gradually increased by the minimum unit until the received signal value is in the adjacent range.

[0078] Optionally, in this embodiment, an automatic adjustment mechanism is introduced, and the tag will automatically adjust the working power according to the working state of the tag. The tag can minimize the power consumption while ensuring the reliability of the transmission information, and uses the minimum power for signal transmission and reception. Similarly, the transmitting power can be automatically adjusted when the position of the tag changes, so as to ensure that the push picture success rate is at a stable and high level. That is, when the tag moves from a close distance to a far distance, the transmitting power of the tag will automatically increase, and when the tag moves from a far distance to a close distance, the working transmitting power of the tag will automatically decrease.

[0079] Optionally, in this embodiment, an entry threshold related to RSSI (signal strength) and a receiving threshold are introduced, and the entry registration and picture transmission of each tag are carried out according to the RSSI signal value. Among them, the tag selects the base station with the optimal signal value according to the RSSI signal to register and enter the network, and after completion, starts to listen to the base station signal and receives the price picture and other information. It should be understood that the transmitting power of the base station is generally higher than that of the tag, and the signal received by the tag is higher than that received by the base station, so the minimum RSSI value required for the electronic tag to normally enter the network and successfully push the picture business needs to be referred to the transmitting power of the tag and the signal value received by the base station.

[0080] Optionally, in the embodiment, first, a theoretical network access RSSI threshold is set according to the environment and the barrier blocking the price tag, and the threshold is set slightly higher than the minimum RSSI value of successful network access, considering the dynamic fluctuation of RSSI. When the RSSI value fluctuates near the threshold, the embodiment defines a basic transmission power. At this time, the transmission power can be dynamically adjusted according to the comparison value of RSSI and the threshold at this time, and dynamically fluctuates near the basic power, which synchronously reduces the interference to the signal, and finally makes the power and the RSSI signal value stable, and ensures the network access and the success of picture transmission and reception.

[0081] Optionally, in the embodiment, it needs to be explained that, considering that the base station and the price tag use the same working frequency, the base station transmits signals and the price tag transmits signals of the same frequency, which can be understood as the same attenuation and interference ratio. Therefore, when the base station signal is poor, the price tag signal transmitted to the base station is also poor, and vice versa. When the base station signal quality received by the price tag is improved, the base station signal received after the price tag transmits is also improved. Based on this, in the embodiment, the price tag can judge that the strength of the price tag transmitted signal changes synchronously by measuring the change of the signal strength transmitted by the base station, which is used as a functional strategy scheme point of the embodiment.

[0082] Specifically, in the embodiment, first, in the idle state, the transmission power of the price tag is gradually reduced, and the received signal value when accessing the same base station is recorded; then, the lowest transmission power when failing to access the base station and the corresponding lowest received signal value are recorded, and the minimum unit incremental value of the lowest transmission power is used as the transmission power threshold of the price tag, and the lowest received signal value is used as the comparison threshold of the signal test value; in the subsequent implementation process, the received signal value of the price tag is monitored when the price tag is in the network access state. If the received signal value is greater than the comparison threshold, the minimum unit of the current transmission power is gradually reduced until the received signal value is in the adjacent range of the comparison threshold, and if the received signal value is less than the comparison threshold, the minimum unit of the current transmission power is gradually increased until the received signal value is in the adjacent range.

[0083] The beneficial effect of the embodiment is that, by successively reducing the transmitting power of the price tag in the idle state, and recording the received signal value when successively accessing the same base station, recording the lowest transmitting power and the corresponding lowest received signal value when failing to access the base station, and taking the minimum unit increment of the lowest transmitting power as the transmitting power threshold of the price tag, and taking the lowest received signal value as the comparison threshold of the signal test value, when the price tag is in the access state, the received signal value of the price tag is monitored, if the received signal value is greater than the comparison threshold, the current transmitting power is successively reduced by the minimum unit until the received signal value is in the adjacent range of the comparison threshold, if the received signal value is less than the comparison threshold, the current transmitting power is successively increased by the minimum unit until the received signal value is in the adjacent range. A high-efficiency and flexible price tag power dynamic regulation scheme is realized, which greatly reduces the power consumption of the price tag under the premise of ensuring the normal work of the price tag, effectively delays the battery life of the price tag, and significantly improves the product competitiveness of the price tag.

[0084] Embodiment two

[0085] Figure 4 is a flowchart of the second embodiment of the price tag power dynamic regulation method of the application, based on the above embodiment, the successively reducing the transmitting power of the price tag in the idle state, and recording the received signal value when successively accessing the same base station, comprises:

[0086] S11, when the price tag is powered on, when no push picture task is received within the first preset time, it is determined to enter the idle state.

[0087] S12, in the idle state, transmitting information with the maximum transmitting power, and after searching for the base station with the highest signal strength, accessing the network.

[0088] Optionally, in the embodiment, when the price tag is powered on, first, access the network with the default power, monitor the base station signal and transceiving information.

[0089] Optionally, in the embodiment, when the price tag waits for the first preset time, for example, about 30 minutes, and no push picture task, the price tag automatically enters the power threshold determination state. In this state, the stage of transmitting information with the maximum transmitting power, and after searching for the base station with the highest signal strength, accessing the network is started.

[0090] The beneficial effect of the embodiment is that when the price tag is powered on, when a push map task is not received within a first preset time, it is determined to enter the idle state; in the idle state, information is sent at the maximum transmission power, and after searching for a base station with the highest signal strength, it is accessed into the network. The threshold strategy before making a decision is provided to realize an efficient and flexible price tag power dynamic regulation scheme, the power consumption of the price tag is greatly reduced under the premise of ensuring the normal work of the price tag, the battery life of the price tag is effectively delayed, and the product competitiveness of the price tag is significantly improved.

[0091] Embodiment three

[0092] Figure 5 The flowchart is a third embodiment of the price tag power dynamic regulation method, based on the above embodiment, in the idle state, the transmission power of the price tag is gradually reduced, and the received signal value when accessing the same base station is recorded, and the method further comprises:

[0093] S13, when successfully accessing the base station with the highest signal strength, the base station and the current received signal value are recorded.

[0094] S14, gradually reducing the transmission power of the price tag based on the maximum transmission power in the minimum unit.

[0102] Optionally, in the embodiment, the same network entering and exiting actions are repeatedly executed, and the related results are gradually recorded, as follows:

[0103] 6dB, RSSI=90;

[0104] 5dB, RSSI=80;

[0111] Embodiment five

[0112] Figure 7 is a flow chart of the fifth embodiment of the price tag power dynamic regulation method, based on the above embodiment, the transmitting power of the price tag is gradually reduced in the idle state, and the received signal values when entering the same base station are recorded, and the embodiment further comprises the following steps:

[0114] S18, if the network access to the base station fails within the second preset time, determining the current transmission power as the lowest transmission power when the network access to the base station fails.

[0115] Optionally, in the embodiment, it needs to be explained that the recorded multiple pairs of associated current transmission power and current received signal value are recorded in an ideal case. Generally, when the price tag is reduced to 2dB, it may have failed to access the network successfully, or the probability is very low, at this time, the embodiment sets a second preset time, for example, 10 minutes, to detect whether the network access within the time period. Based on this, the embodiment records the lowest power and signal value when the network access fails, for example, sets the power value when the network access and the push chart probability is reduced to 90% as the lowest power of the price tag at this position, and the signal value as the network access threshold: such as m=2dB, RSSI=50.

[0116] The beneficial effects of the embodiment are that when the first network access to the base station fails, the network access operation of the base station is repeatedly performed with the same transmission power within a second preset time; if the network access to the base station fails within the second preset time, the current transmission power is determined as the lowest transmission power when the network access to the base station fails.

[0119] S21, taking the minimum unit incremental value of the lowest transmission power as the transmission power threshold of the price tag.

[0120] S22, according to the corresponding relationship, determining the received signal value corresponding to the transmission power threshold as the comparison threshold of the signal test value.

[0121] Optionally, in this embodiment, based on the above embodiment, the tag is set to work at a threshold M = m + 1 = 3dB as the transmission power threshold.

[0122] Optionally, in this embodiment, similarly, RSSI = 50 is set as the signal test value comparison threshold N.

[0123] Optionally, in this embodiment, the power adjustment reference threshold M = 3dB of the tag in this environment is determined, and the base station reference RSSI threshold N = 50 is measured by the tag.

[0124] The beneficial effects of this embodiment are that the minimum unit incremental value of the minimum transmission power is taken as the transmission power threshold of the tag, and the corresponding relationship is determined to take the received signal value corresponding to the transmission power threshold as the comparison threshold of the signal test value. Two threshold setting methods are provided to realize an efficient and flexible tag power dynamic regulation scheme, which greatly reduces the power consumption of the tag under the premise of ensuring the normal operation of the tag, effectively delays the battery life of the tag, and significantly improves the product competitiveness of the tag.

[0125] Embodiment Seven

[0126] Figure 9 is a flowchart of the seventh embodiment of the tag power dynamic regulation method of the present application, based on the above embodiment, the monitoring of the received signal value of the tag when the tag is in the network state comprises:

[0127] S31, monitoring whether the base station in the network state is replaced.

[0128] S32, if the tag is replaced to a new base station, the transmission power threshold corresponding to the new base station and the comparison threshold are determined in the idle state.

[0129] Optionally, in this embodiment, the threshold of the tag is recorded in the database after the determination of the threshold of the tag in the network state is completed, and the future reference threshold is used to automatically adjust the working power state. If the stable base station registered by the tag changes, the tag will re-adjust the threshold. That is, when the tag registers different base stations, the reference threshold may not be the same as the original base station. Similarly, the work of measuring and determining the new threshold of the tag must be performed when there is no related push information sent in the system.

[0130] The beneficial effect of the embodiment is that by monitoring whether the base station in the network entry state is replaced, if the price tag is replaced to a new base station, the transmit power threshold and the comparison threshold corresponding to the new base station are determined in the idle state. The update condition of the threshold is provided to realize an efficient and flexible price tag power dynamic regulation scheme, the power consumption of the price tag is greatly reduced under the premise of ensuring the normal work of the price tag, the battery life of the price tag is effectively delayed, and the product competitiveness of the price tag is significantly improved.

[0131] Embodiment eight

[0132] Figure 10 The flowchart is the eighth embodiment of the price tag power dynamic regulation method, based on the above-mentioned embodiment, the receiving signal value of the price tag in the network entry state is monitored, which comprises:

[0133] S33, monitoring whether the channel connected to the base station in the network entry state is replaced.

[0134] S34, if the price tag is replaced to a new channel, the transmit power threshold and the comparison threshold corresponding to the new channel are determined in the idle state.

[0135] Optionally, in the embodiment, the threshold of the price tag is recorded in the database after the determination of the base station in the network entry is completed, and the future reference threshold is used to automatically adjust the working power state; wherein, if the stable base station registered by the price tag in the network entry changes, the price tag will re-adjust the threshold. That is, when the price tag is connected to different channels of the base station, the reference threshold may not be the same as the channel of the original base station. Similarly, the work of measuring and determining the new threshold of the price tag must be carried out when there is no related push information sent in the system.

[0136] Specifically, for example, when the price tag works near the M=3dB threshold, with the change of the environment and the fluctuation of the signal, it gradually rises and falls, when RSSI=60>N, the transmit power of the price tag is reduced to M-1=2dB, when RSSI=40<50, the transmit power is appropriately increased, M+1=3dB, so as to ensure the network entry and the successful push of the map.

[0137] The beneficial effect of the embodiment is that by monitoring whether the base station in the network entry state is replaced, if the price tag is replaced to a new base station, the transmit power threshold and the comparison threshold corresponding to the new base station are determined in the idle state. The update condition of the threshold is provided to realize an efficient and flexible price tag power dynamic regulation scheme, the power consumption of the price tag is greatly reduced under the premise of ensuring the normal work of the price tag, the battery life of the price tag is effectively delayed, and the product competitiveness of the price tag is significantly improved.
