Description

Technical Field

[0001] The utility model relates to the technical field of power supply for monitoring equipment, in particular to a GNSS monitoring equipment with real-time battery heating. Background Art

[0002] As the country pays more and more attention to safety monitoring, more and more units and individuals choose GNSS equipment to monitor dangerous objects such as slopes, goafs, landslides, dams, etc. to reduce property losses and ensure life safety. At present, in order to meet the 7*24 hours real-time monitoring of the monitored objects, solar energy systems are usually used with batteries to power GNSS equipment, which has high requirements for data real-time performance.

[0003] The average power consumption of GNSS equipment is not high, but it needs to collect data in real time around the clock, so the cumulative power consumption is relatively large. In addition, during the critical time period before and after the danger occurs, the amount of data transmitted is large, and the power consumption also increases accordingly. However, conventional batteries generally have reduced storage capacity in cold winter temperatures, and even in extreme low temperatures, the battery is directly frozen and cannot work normally. Therefore, ensuring a stable power supply for GNSS equipment is critical to the smooth operation of GNSS monitoring equipment, and this is also a problem that needs to be solved urgently. Summary of the invention

[0004] In view of the above problems in the prior art, the utility model provides a GNSS monitoring device with real-time battery heating, which solves the problem of insufficient battery power in low temperature environments, especially in key monitoring time periods, so as to meet the requirements of real-time monitoring data around the clock.

[0009] The built-in thermistor NTC is used to determine the ambient temperature inside the battery pack. When the ambient temperature is lower than the set temperature value, the battery pack heater will automatically heat the battery pack to ensure that the battery pack is always in a relatively constant temperature state; the temperature will not drop to a level where the battery performance decreases to ensure that the GNSS device is always in an ideal battery power supply environment, and the battery performance will not decrease due to low temperature and power outages that prevent it from working normally.

[0029] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0031] like Figure 1 As shown, a GNSS monitoring device with real-time battery heating includes a GNSS signal transmission module and a solar panel 5 arranged on one side of the GNSS signal transmission module. The solar panel 5 converts light energy into electrical energy and stores it in a battery pack to provide electrical energy for the GNSS signal transmission module.

[0032] The GNSS signal transmission module includes a fixing shell 1, a fixing base 2 and a power supply base 3 from top to bottom, and a solar panel 5 is connected to one side of the fixing base 2. A PCB board 21 is provided above the fixing base 2. The fixing base 2 has a stable structure and can ensure the stable connection of the solar panel 5.

[0033] The battery pack 4 of the power supply seat 3 is provided with a heating plate 32 connected to the PCB board 21 on the outside of the battery pack 4, and the battery pack 4 is a lithium battery. The heating plate 32 is a serpentine-wound belt structure and is embedded in the battery pack 4 to ensure stable heating of the battery pack 4.

[0034] In this embodiment, the heating plate 32 is an S-shaped frame structure, and the batteries of the battery pack 4 are orderly distributed inside and outside the heating plate 32, so that the battery pack 4 is always in a stable temperature working environment. Figure 2 As shown, a thermistor 33 connected to the PCB board 21 is provided inside the battery of the battery pack 4. The thermistor 33 is an NTC and can feed back to the PCB board 21 according to the temperature environment around the battery, thereby adjusting the ambient temperature.

[0035] The upper and lower sides of the battery pack 4 of the power supply seat 3 are provided with fixed brackets 34, which provide support for the battery pack 4 to ensure stable connection of the battery. The outer sides of the fixed brackets 34 are provided with insulating sheets 35 to ensure the safety of the battery pack 4. A battery pack main board 39 connected to the battery pack 4 is also provided between the upper insulating sheet 35 and the upper fixed bracket 34, and a support plate 36 located at the bottom of the fixed seat 2 is provided on the outer side of the upper insulating sheet 35, and the support plate 36 further ensures the stability of the battery pack.

[0036] There is a reinforcing strip 37 on the outside of the battery pack 4, and there is a PVC ring 38 on the outside of the reinforcing strip 37. The height of the reinforcing strip 37 is lower than the height of the PVC ring 38, which ensures that the reinforcing strip 37 can stably fix the battery pack 4. The height of the PVC ring 38 ensures that the battery pack 4 is stably inserted therein, and at the same time, the safety performance of the battery pack is further improved. A battery shell 31 connected to the bottom of the fixing seat 2 is provided on the outside of the PVC ring 38, and the height of the battery shell 31 is higher than the height of the PVC ring 38, which ensures the stable connection of the battery pack.

[0037] When the GNSS monitoring device of the utility model is running, in a harsh environment, the heating plate 32 keeps heating the battery pack 4 to ensure the stable performance of the battery pack 4, thereby providing stable power supply to the GNSS monitoring device. The battery pack is left at low temperature for 12 hours. After the temperature reaches -30 degrees, the heating plate 32 starts to work. Temperature probes are placed at seven locations to observe the temperature changes over time. The temperature measurement results are as follows: Figure 3 shown.

[0038] Therefore, the utility model adopts the above-mentioned GNSS monitoring device with real-time battery heating, and judges the ambient temperature inside the battery of the battery pack through the built-in thermistor NTC. When the ambient temperature is lower than the set temperature value, the heating plate will automatically heat the battery pack to ensure that the battery pack is always in a relatively constant temperature state.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model 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 utility model.
