Description

Comprehensive gateway device supporting High Performance Liquid Chromatography (HPLC) communication

Technical Field

The utility model relates to a gateway technical field specifically is a support comprehensive gateway device of HPLC communication.

Background

With the rapid development of power grid technology, a large number of things sensing monitoring devices are connected to an electricity utilization network, and different device brands use respective communication protocols due to the lack of unified specifications and management at present. The huge number of devices and different device protocols cause great inconvenience to the unified use of the master station for device data acquisition and management. The gateway can collect and manage the sensing equipment respectively and then report the data to the relay communication equipment of the master station in a unified way, and the gateway can be produced at the discretion. The communication modes used by the current gateway in the using process are various, such as 485 communication, serial port communication, network port communication, switching value signals and the like, in order to support various communication modes, most of the integrated gateways on the market provide support for various communication interfaces, but a gateway product capable of supporting HPLC communication does not exist at present. To this end, we propose an integrated gateway device supporting HPLC communication.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a support comprehensive gateway device of HPLC communication to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a comprehensive gateway device supporting HPLC communication comprises a metal shell, wherein a core circuit board and an interface board are assembled in the metal shell, a CPU module, a power supply module, an HPLC module and an Ethernet module are arranged in the core circuit board, and an interface module and a 4G module are arranged in the interface board.

Preferably, the interface module includes a first port, a second port, a third port, a fourth port, a fifth port and a sixth port mounted on the side wall of the metal housing.

Preferably, an RTC clock function module is disposed in the core circuit board.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a comprehensive gateway device of supporting HPLC communication, sets up HPLC module and interface module rather than the complex in this device, makes this device become the comprehensive gateway equipment that can support multiple communication modes such as HPLC communication mode, has satisfied the access demand of thing allies oneself with sensing equipment of HPLC communication, is applicable to the condition far away between each equipment distance in large-scale garden.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a comprehensive gateway device supporting HPLC communication comprises a metal shell 7, wherein a core circuit board and an interface board are assembled in the metal shell 1, a CPU module, a power supply module, an HPLC module and an Ethernet module are arranged in the core circuit board, and an interface module and a 4G module are arranged in the interface board.

The core circuit board is a circuit board with the model of IAC-IMX6UL-KIT, and a 4-layer PCB high-precision process is adopted, so that the core circuit board has the best electrical performance and anti-interference performance. The CPU, the EMMC, the RAM, the power supply, the crystal oscillator and the like are integrated, up to 160 leading-out pins are led out, and different interface functions can be combined through multiplexing pins.

The power module is a WAB20DI-1205 power module, and when overvoltage is input, the power supply is reliably protected, and the high-voltage working reliability can be improved. When the power output end has overcurrent or short circuit, the power supply can be reliably protected, and the power supply and the system are prevented from being damaged.

The HPLC module adopts a CCO module, and requires a direct current power supply with the voltage of 12V +/-1V, the output current of not less than 400mA, 3.3V +/-0.3V and the current of 150 mA.

The Ethernet module is provided with a standard RJ45 interface with ACT/LINK indicator lights.

The core circuit board is internally provided with an RTC clock function module, the gateway needs time marks for reading data in actual use, and under the condition of network disconnection or power failure, an original network clock can be lost, and the data read later can be incomplete, so that an RTC chip with a battery needs to be selected in the circuit. The clock chip is a DS3231MZ chip with an IIC interface and is provided with a single battery power supply interface, so that the loss of a network clock under the condition of network failure or power failure is avoided.

The interface module comprises a first port 1, a second port 2, a third port 3, a fourth port 4, a fifth port 5 and a sixth port 6 which are assembled on the side wall of a metal shell 7.

The first port 1 is used for DEBUG, the fourth port 4 is used for communicating with the HPLC module, the

third ports

2, 3 and 5 are used for supporting 485 connection communication, and the sixth port 6 is a reserved port and used for communication of other modules in the interface board, such as an LORA module or a bluetooth communication module.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
