Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping safety monitoring, and in particular to a GNSS receiver and a method for reducing the power consumption of the receiver. Background Art

[0002] In order to achieve high integration of GNSS receivers and facilitate transportation and installation, GNSS receivers currently choose to integrate solar panels, machines and batteries. However, for the sake of the beauty and coordination of the equipment, only small solar panels can be used, and it is difficult to achieve charge and discharge balance.

[0003] Considering that the solution software generally produces a solution result every half an hour to an hour, normal solution can be achieved as long as the data can be pushed to the solution software completely during this period. In this way, the receiver can be controlled to cache data within a period of time, and the 4G communication module will be put to sleep during the cache period. After the cache time is up, the 4G communication module will be awakened to send the data to the solution software. Compared with traditional real-time data transmission solutions, this method can greatly reduce the power consumption of the device and achieve the balance of device charging and discharging. Summary of the invention

[0004] The purpose of the present invention is to provide a GNSS receiver and a method for reducing the power consumption of the receiver, and solve the problems raised in the above-mentioned background technology through a data cache transmission method, so as to realize low-power operation of the equipment without affecting the solution accuracy and solution effect.

[0005] To achieve the above-mentioned purpose, the present invention provides a GNSS receiver, including a receiver body, a main board is arranged inside the receiver body, a main control chip, a 4G communication module and a positioning module are arranged on the main board, the positioning module and the 4G communication module are respectively connected to the main control chip through data cables, the main board is respectively connected to the solar panel and the battery through power cables, the solar panel is connected to the outside of the receiver body, the battery is arranged inside the receiver body, and is connected to the main board through a connecting wire.

[0006] Preferably, when there is sunlight, the solar panel powers the main control chip, 4G communication module and positioning module, and stores the remaining electric energy in the battery; when the electric energy provided by the solar panel cannot meet the power supply requirements of the main control chip, 4G communication module and positioning module, the battery provides power to meet the power supply requirements.

[0007] Preferably, a random access memory RAM is provided on the main control chip. When the main control chip receives the position data sent by the positioning module, the main control chip first stores the position data in the random access memory.

[0008] Preferably, two independent cache areas are provided in the random access memory RAM. When one cache area is being read to prepare to send position data, the other cache area continues to receive new position data, thereby ensuring the continuity and integrity of the data.

[0009] Preferably, a timer is provided in the main control chip, and the setting time of the timer is 10 minutes. Within 10 minutes, the location data collected by the main control chip is stored in the cache area and is not sent. When the setting time of the timer is reached, the main control chip starts the 4G communication module, packages all the location data in the cache and sends it to the server solution software through the 4G network.

[0010] A method for reducing power consumption of a GNSS receiver comprises the following steps:

[0011] Step S1, first check the voltage level of the solar panel in the initialization stage to determine whether the solar panel is powered; if not, switch to battery power supply;

[0012] Step S2, entering a low-power listening state, waiting for the location data transmitted by the positioning module. After receiving the location data, the main control chip writes it into the buffer area currently in use, and keeps the 4G communication module in a dormant state to save energy;

[0013] Step S3: After every 10 minutes, the main control chip completes a data upload process, including waking up the 4G communication module, combining all the location data in the first cache area to form a data packet and sending it to the server. During this period, any new location data will be written to the second cache area. After the location data is sent, the 4G communication module is put into sleep mode again, and the two cache areas exchange reading and storage functions.

[0014] Therefore, the present invention adopts the above-mentioned GNSS receiver and the method for reducing the power consumption of the receiver, which has the following beneficial effects:

[0015] (1) Reduce the energy consumption of the receiver and save energy.

[0016] (2) There will be no imbalance in charging and discharging, no need for manual maintenance, and no situation where the battery runs out and the equipment fails to work.

[0017] (3) It can ensure data integrity and reliability while reducing device power consumption.

[0018] (4) No hardware changes are required, only software adjustments are required.

[0023] Example

[0024] See also Figure 1 The present invention provides a GNSS receiver, including a receiver body, a mainboard is arranged inside the receiver body, a main control chip, a 4G communication module and a positioning module are arranged on the mainboard, the positioning module and the 4G communication module are respectively connected to the main control chip through data lines, the mainboard is respectively connected to the solar panel and the battery through power lines, the solar panel is connected to the outside of the receiver body, the battery is arranged inside the receiver body, and is connected to the mainboard through a connecting line. When there is sunlight, the solar panel supplies power to the main control chip, the 4G communication module and the positioning module, and stores the remaining power in the battery; when the power provided by the solar panel cannot meet the power supply requirements of the main control chip, the 4G communication module and the positioning module, the battery supplies power to meet the power supply requirements.

[0025] The main control chip is responsible for the control and coordination of the entire system and manages the working status of each module. The main control chip is equipped with a random access memory RAM. When the main control chip receives the location data sent by the positioning module, in order to reduce the additional power consumption caused by the continuous operation of the 4G communication module, the main control chip first stores the location data in the random access memory instead of sending it out immediately. There are two independent cache areas in the random access memory RAM. In order to avoid the loss of new data during the sending process, the main control chip uses two independent cache areas to switch in turn: when one cache area is being read to prepare to send location data, the other cache area continues to receive new location data to ensure the continuity and integrity of the data.

[0026] A timer is set in the main control chip, and the setting time of the timer is 10 minutes. Within 10 minutes, the location data collected by the main control chip is stored in the cache area and is not sent. When the setting time of the timer is reached, the main control chip starts the 4G communication module, packs all the location data in the cache at one time and sends it to the server solution software through the 4G network.

[0027] The method for reducing the power consumption of the GNSS receiver comprises the following steps:

[0028] Step S1, first check the voltage level of the solar panel during the initialization phase to determine whether it is possible to supply power only through the solar panel; if not, switch to battery power supply;

[0029] Step S2, entering a low-power listening state, waiting for the location data transmitted by the positioning module. After receiving the location data, the main control chip writes it into the buffer area currently in use, and keeps the 4G communication module in a dormant state to save energy;

[0030] Step S3: After every 10 minutes, the main control chip completes a data upload process, including waking up the 4G communication module, combining all the location data in the first cache area to form a data packet and sending it to the server. During this period, any new location data will be written to the second cache area. After the location data is sent, the 4G communication module is put into sleep mode again, and the two cache areas exchange reading and storage functions.

[0031] Through the above method, the overall power consumption of the receiver can be significantly reduced without affecting the data integrity, thereby improving the reliability and durability of the system and reducing the maintenance cost.

[0032] Therefore, the present invention adopts the above-mentioned GNSS receiver and the method for reducing the power consumption of the receiver to reduce the energy consumption of the receiver and save energy; there will be no imbalance in charging and discharging, no need for manual maintenance, and no failure of the device due to battery exhaustion; it can ensure data integrity and reliability while reducing the power consumption of the device; no changes to the hardware are required, only software adjustments are required.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
