[0011] As Figure 1 As shown, the dual wireless temperature and humidity acquisition device with an external battery includes a battery compartment 2 and a main body 1 of the acquisition device. The main body 1 of the acquisition device includes a housing and a circuit board inside. Two battery contacts, positive and negative, are provided on the back of the housing. The battery compartment 2 includes a protective case and a rechargeable battery inside. The rechargeable battery is connected to the battery contacts through elastic metal keys to supply power to the circuit board. A notch is also provided at the upper end of the protective case for exposing the plug 3 that is movably connected to the main body 1 of the acquisition device.

[0012] The protective case wraps the rear panel and the side surface of the main body 1 of the acquisition device. An elastic buckle 6 is provided at the upper end of the protective case, and a bent portion 4 is provided at the lower end for further buckling the main body 1 of the acquisition device. The elastic buckle 6 is used to buckle the upper end of the front panel of the main body 1 of the acquisition device, and the bent portion 4 is used to buckle the lower end of the front panel of the main body 1 of the acquisition device. When placing the main body 1 of the acquisition device into the protective case, the lower end of the main body 1 of the acquisition device is placed on the bent portion 4, and the upper end is pressed into the elastic buckle 6, and the main body 1 of the acquisition device is clamped by the elastic buckle 6; when it is necessary to take out the main body 1 of the acquisition device, the elastic buckle 6 is pulled outward, and the main body 1 of the acquisition device can be taken out from the protective case. On two side surfaces of the protective case, a first groove 7 and a second groove 8 are provided opposite to each other, which is convenient for taking out the main body 1 of the acquisition device. The first groove 7 and the second groove 8 are semi-circular. A wire passing hole 5 is provided at the lower end of the protective case for tying a rope.

[0013] The housing of the main body of the acquisition device includes an upper shell and a lower shell with a snap-fit structure. The snap-fit parts that snap around use a lower convex and upper concave fit. A rubber ring is used for sealing around the snap-fit parts. Through the rubber ring, waterproof sealing inside the shell is achieved, thereby solving the problems of waterproofing and dustproofing in the actual use environment. Only one USB TYPE-C interface is provided on the housing, which is used to insert the USB TYPE-C plug 3. The interface is used to realize three functions: charging, external connection of probe signals, and internal program upgrade. For better waterproof sealing treatment of the interface, a waterproof USB socket is used. A display screen and buttons are provided on the front panel of the housing. By integrally pasting the front panel with a transparent mask with adhesive, sufficient sealing can be ensured.

[0014] Combined with Figure 2As shown in the figure, the circuit board inside the main body of the acquisition device is provided with a CPU control chip, a Lora-RF chip, an LCD module, a storage chip, and a key (KEY) that are respectively connected to the CPU control chip. It also includes a USB TYPE-C interface for providing charging and data transmission and charging. The Lora-RF module uses the SX1278 chip, which is a multi-channel spread-spectrum communication LORA transceiver chip with the characteristics of long communication distance and strong anti-interference ability. The Lora-RF module is connected to the Lora antenna to achieve Lora wireless transmission.

[0015] The CPU control chip uses the CH579M chip. This CPU is a domestic high-performance and low-power 32-bit ARM chip with a built-in Bluetooth transceiver. By connecting to a Bluetooth antenna, it realizes the Bluetooth communication function, which is convenient for signal transmission, on-site setting, and management during use. This Bluetooth function operates with ultra-low power consumption, and the working monitoring state can last for more than one year. In addition to the built-in Bluetooth function, the CPU control chip can also be used to control LORA communication. During the sampling interval, the chip enters the deep sleep state.

[0016] The CPU control chip is also connected to the LCD module of the LCD display through the VKL060 chip. The data display of the LCD display is completed by this ultra-low-power chip for LCD refresh processing. In this way, during the monitoring interval, the CPU control chip can enter the deep sleep state, and only the VKL060 performs the LCD screen display under micro-power consumption. The storage chip uses FLASH Q64 to achieve data storage.

[0017] This utility model is placed outside the medical incubator. The external probe sensor used is a connecting probe with a lead. The probe is connected into the medical incubator to facilitate the measurement of the temperature and humidity inside the medical incubator. This utility model can also switch to an internal probe. At this time, the sensor is installed in the plug, and the entire device is placed inside the medical incubator for use. By using its built-in Bluetooth transceiver, this utility model can conveniently transmit the recorded parameters to a nearby mobile phone, PC, or Bluetooth printer at high speed. Its internal Lora wireless transmission can transmit the collected information to a collection device within 1 kilometer nearby for real-time monitoring.

[0018] On the inner side of the protective case, there is a first groove for buckling the battery cover 9; the inside of the first groove is a second groove for placing a rechargeable battery. The positive and negative electrodes of the rechargeable battery are connected to the elastic metal keys in the middle of the battery cover 9. Figure 3 As shown in the figure, after the rechargeable battery is fixed in the second groove, the battery cover 9 is buckled into the first groove. The part where the battery cover 9 contacts the first groove is fixed with glue, so that the rechargeable battery can be sealed to achieve the first level of waterproof and dustproof.

[0019] After the battery cover 9 is fastened, a rubber waterproof layer 10 is pasted at the joint between the battery cover 9 and the first groove. The rubber waterproof layer 10 is made of rubber material and covers the joint below. When the main body 1 of the acquisition device is located in the protective case, the upper surface of the rubber waterproof layer 10 can contact the rear panel of the main body 1 of the acquisition device, realizing the second level of waterproof and dustproof, and separating the elastic metal keys from the outside connection. Further, the battery cover 9 is provided with a sealing layer 11 on the outer sides of the two elastic metal keys. The sealing layer 11 is made of rubber, and its lower surface is pasted on the battery cover 9. When the main body 1 of the acquisition device is located in the protective case, the upper surface of the sealing layer 11 contacts the rear panel of the main body 1 of the acquisition device, realizing the third level of waterproof and dustproof.

[0020] As Figure 4 shown, there are two elastic metal keys, namely the first metal key 12 and the second metal key 13, which are respectively connected to the positive and negative electrodes of the rechargeable battery. The elastic metal keys are fixedly installed on the battery cover 9. The elastic metal key includes a metal key cap 14 and a metal sheet 17. A spring 16 and a metal wire 15 are arranged between the metal key cap 14 and the metal sheet 17. One end of the metal wire 15 is welded to the metal sheet 17, and the other end is welded to the lower end of the metal key cap 14. Similarly, one end of the spring 16 is welded to the metal sheet 17, and the other end is welded to the lower end of the metal key cap 14. The metal wire 15 is within the range of the spring 16.

[0021] The lower end of the metal key cap 14 is flat, and the upper end is arc-shaped. The upper end can contact the battery contact on the back of the casing. The metal wire 15 can limit the maximum distance between the metal key cap 14 and the metal sheet 17. When the main body 1 of the acquisition device is placed in the protective case, the spring 16 will be compressed. The spring 16 can provide a elastic force to the metal key cap 14, so that the metal key cap 14 can be in close contact with the battery contact. Further, the other side of the metal sheet 17 is connected to the positive or negative electrode of the rechargeable battery.

[0022] The usage steps of the present utility model are as follows: After the device is fully charged, set the monitoring working parameters (sampling interval, sending interval, uploading collector address, etc.), and then connect the built-in sensor or the wired external sensor according to the on-site needs. When it is built-in, put the device into the incubator to be monitored. When it is external, put the device into the fixed bag outside the box, and extend the probe into the incubator. In this way, the device enters the working state of temperature and humidity monitoring and recording. Every time the sampling interval is reached, a set of temperature and humidity data will be collected and stored in the FLASH. When the sending interval is reached, multiple sets of recorded data in the FLASH will be sent to the collector by LORA. When a Bluetooth request interruption occurs during the entire monitoring working state, the interruption will be responded to and the corresponding service program (data uploading or Bluetooth printing) will be executed.

[0023] As Figure 5 shown, the plug 3 has three connection functions (3-in-1 charging + probe + download). To reduce the number of jacks and improve the sealing of the housing, the charging pins of this USB socket are fully compatible with standard USB charging cables, and the present utility model can be charged with a standard USB cable. Additionally, the other unused pins of the USB are defined as functional pins for external probes and pins for downloading programs.

[0024] The 12 pins of the plug are connected to different pins in different usage scenarios:

[0025] 1. When downloading a new program, connect with the pins of a standard USB cable: GND, +5V, D+, D-, RESET.

[0026] 2. When monitoring temperature and humidity, connect with the pins of a dedicated sensor probe connector: GND, VDD, SS-DAT, SS-CLK.

[0027] 3. When the device is charging, connect with the pins of a standard USB cable: GND, +5V.

[0028] This connector supports the plug to be inserted in both forward and reverse directions (directionless).

[0029] The main body of the acquisition device can achieve high-precision acquisition and storage of temperature and humidity information, and perform data transmission through a wireless LORA transceiver and a wireless BLE Bluetooth transceiver. It can collect the recorded monitoring data both at short distances and long distances.

[0030] The present utility model has the following advantages: (1) The external battery used in the battery compartment is a rechargeable battery. The battery compartment is convenient and quick to replace, and the replaced battery compartment can also be charged separately; (2) The capacity of the battery compartment can be made larger, greatly improving the battery life of the dual wireless temperature and humidity acquisition device. Moreover, the connection between the external battery and the dual wireless temperature and humidity acquisition device is convenient and easy to use; (3) A rubber waterproof layer is provided between the battery compartment and the main body of the acquisition device, having a better insulation effect.
