In terms of mandatory inspection of charging piles, some charging piles are currently calibrated online using online inspection devices. As a standard instrument, the online inspection device needs to pass the laboratory standard traceability test. The existing online inspection device integrates the temperature sensor on the chip. Due to the slow temperature response speed of the integrated chip, the temperature traceability test time of the online inspection device is as long as more than 8 hours. At the same time, due to the large size of the integrated chip, affected by the size of the high and low temperature chambers of the traceability test, each high and low temperature chamber can only accommodate 5-8 online inspection devices to carry out traceability tests at the same time.

[0026] The utility model provides an online calibration device for charging piles with external temperature sensors. Figures 1 to 4 The temperature sensor external charging pile online calibration device includes:

[0027] The data processing device 100 and the temperature sensor 200 are electrically connected; the data processing device 100 is used to process the temperature data collected by the temperature sensor 200; the data processing device 100 and the temperature sensor 200 can be separated.

[0028] In the above technical solution, the online calibration device for the charging pile with an external temperature sensor includes at least a data processing device 100 and a temperature sensor 200. The key point is that the temperature sensor 200 and the data processing device 100 adopt a split structure, and the two can be separated from each other. When the online calibration device for the charging pile with an external temperature sensor performs online calibration on the charging pile, the temperature sensor 200 can be set inside the charging pile, and the data processing device 100 can be set outside the charging pile. The temperature data collected by the temperature sensor 200 is processed in real time by the data processing device 100, thereby realizing the online calibration of the charging pile. The traditional integrated online calibration device requires that the data processing chip and the temperature sensor 200 be placed in the charging pile at the same time. Compared with the traditional online calibration device, the online calibration device provided by the utility model can avoid the internal temperature of the charging pile from affecting the data processing device 100, thereby improving the data processing speed of the data processing device 100; and avoid the operating temperature of the data processing device 100 from affecting the temperature sensor 200, thereby improving the response speed and measurement accuracy of the temperature sensor 200. Of course, the external charging pile online calibration device provided by the present invention can also place the temperature sensor 200 and the data processing device 100 in the charging pile at the same time when performing online calibration on the charging pile. More importantly, when the temperature sensor external charging pile online calibration device is subjected to a temperature traceability test, the temperature sensor 200 can be set inside a high and low temperature box, and the data processing device 100 can be set outside the high and low temperature box. The high and low temperature box refers to a temperature box with specific different temperature zones. The traditional integrated online calibration device requires that the data processing chip and the temperature sensor 200 be placed in a high and low temperature box at the same time. Compared with the traditional online calibration device, the online calibration device provided by the utility model can avoid the internal temperature of the high and low temperature box from affecting the data processing device 100, thereby improving the data processing speed of the data processing device 100, and thus shortening the duration of the temperature traceability test; and avoiding the operating temperature of the data processing device 100 from affecting the temperature sensor 200, thereby improving the measurement response speed and measurement accuracy of the temperature sensor 200. At the same time, only the temperature sensor 200 is separately arranged in the high and low temperature box, which can greatly reduce the internal space occupied by the high and low temperature box. In a temperature traceability test, the same high and low temperature box can accommodate more temperature sensors 200, so that the temperature traceability test can be performed on more online calibration devices at one time.

[0029] It should be noted that the temperature sensor 200 includes a probe 220 and a main body 210. The main body 210 is the other part of the temperature sensor 200 except the probe 220. For example, the housing and the built-in microprocessor of the temperature sensor 200. The temperature sensor 200 described in this article is placed in a high and low temperature box or a charging pile. The entire temperature sensor 200 can be placed in a high and low temperature box or a charging pile, or only the probe 220 of the temperature sensor 200 can be placed in a high and low temperature box or a charging pile. The latter has a better technical effect.

[0030] Specifically, compared with the traditional online calibration device, the online calibration device provided by the utility model can accommodate 6 times the temperature sensors 200 if only the probe 220 of the temperature sensor 200 is placed in the high and low temperature box during the test, and the measurement response speed of the temperature sensor 200 is increased by 10 times.

[0031] In summary, the temperature sensor external charging pile online calibration device provided by the utility model at least includes a data processing device 100 and a temperature sensor 200 that can be separated from each other. When in use or testing, the temperature sensor 200 can be set only in the charging pile or the high and low temperature box, which can improve the data processing speed of the data processing device 100 and the measurement accuracy of the temperature sensor 200, and can perform temperature traceability tests on more online calibration devices at one time. Therefore, the temperature sensor external charging pile online calibration device provided by the utility model improves the efficiency of temperature traceability tests and solves the problem of low efficiency of temperature traceability tests in existing online calibration devices.

[0032] Specifically, there are at least two different posture relationships between the data processing device 100 and the temperature sensor 200; in at least one of the posture relationships, the data processing device 100 and the temperature sensor 200 are in a separated state.

[0033] Since the temperature sensor 200 needs to be set outside the charging pile or the high and low temperature box and the data processing device 100 needs to be set outside the charging pile or the high and low temperature box during use or testing, the temperature sensor 200 and the data processing device 100 need to have a posture relationship in at least one separated state. During use or testing, the two are switched to the separated state.

[0034] In some of the embodiments, in at least one other posture relationship, the data processing device 100 and the temperature sensor 200 are in a combined state. In order to facilitate the storage of the temperature sensor external charging pile online calibration device, the posture relationship of the data processing device 100 and the temperature sensor 200 in the combined state can also be configured. When not in use or testing, the data processing device 100 and the temperature sensor 200 can be stored in combination.

[0035] Specifically, the data processing device 100 includes a microprocessor.

[0036] In some embodiments, the temperature sensor 200 is connected to the microprocessor via a data transmission line, which has the advantage of being more stable.

[0037] In other embodiments, wireless communication is used between the temperature sensor 200 and the microprocessor. Wireless transmission has the advantage of reducing space occupation. In this embodiment, it is necessary to select a temperature sensor 200 and a microprocessor equipped with a wireless transmission module to establish wireless communication between the two.

[0038] Accordingly, the data processing device 100 further includes a housing for accommodating the microprocessor. In order to realize the combination between the data processing device 100 and the temperature sensor 200, the housing structure is designed so that the temperature sensor 200 can be snapped onto the housing. For example, a slot can be provided on the housing, and the temperature sensor 200 can be snapped into the slot by using an interference fit.

[0039] In some preferred embodiments, the microprocessor is an RN8613 chip, and the temperature sensor 200 is a DHT20 temperature sensor 200. Compared with traditional platinum resistance sensors, the DHT20 temperature sensor 200 has a complete calibration function, a quick response, and strong anti-interference ability. It can maintain long-term working stability in the high voltage and high current environment inside the charging pile, and is therefore more suitable for detecting the internal temperature of the charging pile. At the same time, the RN8613 chip is used as a microprocessor. While meeting the daily data acquisition and processing of the online calibration device for the external temperature sensor charging pile, it has a spare I2C hardware interface in terms of communication, providing a hardware foundation for an external high-precision temperature sensor 200. Therefore, the RN8613 chip includes an I2C hardware interface, and the RN8613 chip is connected to the data transmission line through the I2C hardware interface, that is, the RN8613 chip is connected to the DHT20 temperature sensor 200 through the I2C hardware interface.

[0040] As mentioned above, at least one embodiment of each part of the online calibration device for an external charging pile with a temperature sensor provided by the utility model has been described respectively. It should be noted that the various parts of the online calibration device for an external charging pile with a temperature sensor can be combined using different embodiments to form different embodiments of the online calibration device for an external charging pile with a temperature sensor.

[0041] For example, in a specific overall embodiment, the temperature sensor external charging pile online calibration device includes:

[0042] The data processing device 100 and the temperature sensor 200 are electrically connected; the data processing device 100 is used to process the temperature data collected by the temperature sensor 200; the data processing device 100 and the temperature sensor 200 can be separated. There are at least two different posture relationships between the data processing device 100 and the temperature sensor 200; in at least one of the posture relationships, the data processing device 100 and the temperature sensor 200 are in a separated state; in at least another posture relationship, the data processing device 100 and the temperature sensor 200 are in a combined state. The data processing device 100 includes a microprocessor and a housing, the temperature sensor 200 is connected to the microprocessor by a data transmission line, and the temperature sensor 200 can be snapped onto the housing; the microprocessor is an RN8613 chip, and the temperature sensor 200 is a DHT20 temperature sensor 200; the RN8613 chip includes an I2C hardware interface, and the RN8613 chip is plugged into the data transmission line through the I2C hardware interface.

[0043] The utility model also provides an online calibration system for a charging pile with an external temperature sensor, comprising a charging pile and an online calibration device for the charging pile with an external temperature sensor. The online calibration device for the charging pile with an external temperature sensor is the online calibration device for the charging pile with an external temperature sensor provided by the utility model. When the online calibration system for the charging pile with an external temperature sensor is running, the temperature sensor 200 in the online calibration device for the charging pile with an external temperature sensor is arranged inside the charging pile, and the data processing device 100 in the online calibration device for the charging pile with an external temperature sensor is arranged outside the charging pile.

[0044] In the online calibration system of the temperature sensor external charging pile, since the temperature sensor 200 and the data processing device 100 are in a separated state, they can be respectively arranged inside and outside the charging pile, which can avoid the internal temperature of the charging pile from affecting the data processing device 100, thereby improving the data processing speed of the data processing device 100; and avoid the operating temperature of the data processing device 100 from affecting the temperature sensor 200, thereby improving the response speed and measurement accuracy of the temperature sensor 200.
