[0017] The present invention is further described below in conjunction with the embodiments, but is not intended to be a basis for limiting the present invention.

[0018] Embodiment 1. A hydrological intelligent integrated remote control terminal, such as Figure 1 As shown, it includes a power module P, which supplies power to the first control terminal module QICT1, the second control terminal module QICT2 and the data acquisition control module CK respectively. The first control terminal module QICT1 and the second control terminal module QICT2 are respectively connected to the data acquisition control module CK in communication, and the first control terminal module QICT1 and the second control terminal module QICT2 are respectively connected to the switch SW in communication. The first control terminal module QICT1 and the second control terminal module QICT2 can adopt Huawei's intelligent telemetry terminal, and adopt a dual redundant setting to ensure the long-term stable operation of the equipment. The first control terminal module QICT1 and the second control terminal module QICT2 can access the existing water level, rainfall, flow rate and other data monitoring and sensing equipment through the data acquisition control module CK.

[0019] like Figure 2As shown, the data acquisition control module CK includes a control chip MCU, which is respectively connected to a rainfall acquisition interface module DI, an RS232 interface module 1, an RS485 interface module 2, an RS422 interface module 4, a real-time clock module RTC, a wireless communication module LOVA, a switch output module DO, an analog acquisition module ADC-IN, an Ethernet interface module ETH and a USB interface module 3. The control chip MCU adopts an IMX6 chip, and the control chip MCU is also connected to a power supply module POWER and a power output module POWER_OUT. The data acquisition control module CK provides a rich and comprehensive interface that can be connected to various hydrological terminal devices.

[0020] like Figure 3 As shown, the analog quantity acquisition module ADC-IN includes a power switch module composed of a field effect tube Q7, a transistor T8, a first resistor R76, a second resistor R78 and a third resistor R79. The output end of the field effect tube Q7 is filtered by the fifth capacitor C105, the fourth capacitor C104, the third capacitor C103 and the second capacitor C102 to supply power to the isolated power supply U19. The output end of the isolated power supply U19 is filtered by the first capacitor C101 and the sixth capacitor C100 to supply power to the input end of the isolated operational amplifier U18. The input end of the isolated operational amplifier U18 is connected to the signal input end CURR through a current protection module composed of a self-recovery insurance F5, a second diode D12, a fourth resistor R72 and a fifth resistor R73. The output end of the isolated operational amplifier U18 is powered by the field effect tube Q7, and the output end of the isolated operational amplifier U18 is connected to the signal output end AIN2 through a voltage conditioning module composed of a sixth resistor R74, a seventh resistor R75, an eighth resistor R77 and a third diode D13.

[0021] The RS232 interface module 1 is connected to the Beidou communication module, and the RS485 interface module 2 is connected to the water level output module, the profile flow meter, the evaporation sensor, the radar flow meter and the water level sensor.

[0022] The power module P is connected to the first control terminal module QICT1 and the second control terminal module QICT2 through the terminal switch K. The power module P is connected to the terminal switch K. The terminal switch K is connected to the data acquisition control module CK through the first switch K1 and the second switch K2 respectively. The control terminal module and the data acquisition control module CK can be manually powered off through the terminal switch K, the first switch K1 and the second switch K2 respectively.

[0023] The switch SW is connected to the water level camera and the water flow camera, and the data of the water level camera and the water flow camera are transmitted to the first control terminal module QICT1 and the second control terminal module QICT2 through the switch SW and the network cable.

[0024] The power module P is connected to the mains via an intelligent circuit breaker QF. The power module P is also connected to a solar power supply module and a battery module respectively. The intelligent circuit breaker QF is grounded via a lightning protection module BL.

[0025] This hydrological intelligent integrated remote control terminal, the data acquisition control module CK adopts analog acquisition module, USB interface, RS232 interface, RS485 interface and RS422 interface, as well as special interfaces of other existing equipment, which can meet the data access and transmission requirements of various hydrological monitoring instruments and equipment; the power module P supports the status access of the energy power warehouse system (mains power, solar energy, battery module), realizes the remote operation and maintenance of the power system, and provides adaptation to various application scenarios of other professions through powerful capabilities such as interface expansion and edge computing.

[0026] The analog acquisition module ADC-IN of the data acquisition control module CK adopts the isolation amplifier U18 and related circuit design, so that the external signal input terminal is isolated from the internal circuit. The analog quantity acquisition module ADC-IN includes a power switch module composed of a field effect tube Q7, a transistor T8, a first resistor R76, a second resistor R78 and a third resistor R79. The output end of the field effect tube Q7 is filtered by the fifth capacitor C105, the fourth capacitor C104, the third capacitor C103 and the second capacitor C102 to supply power to the isolation power supply U19. The output end of the isolation power supply U19 is filtered by the first capacitor C101 and the sixth capacitor C100 to supply power to the input end of the isolation amplifier U18. The input end of the isolation amplifier U18 is connected to the signal input end CURR through a current protection module composed of a self-recovery fuse F5, a second diode D12, a fourth resistor R72 and a fifth resistor R73. The output end of the isolation amplifier U18 is powered by the field effect tube Q7. The output end of the isolation amplifier U18 is connected to the signal output end AIN2 through a voltage conditioning module composed of a sixth resistor R74, a seventh resistor R75, an eighth resistor R77 and a third diode D13.

[0027] When a 4~20mA signal is normally connected, the current of the signal input terminal CURR returns to the negative electrode of the signal input terminal CURR through the self-recovery fuse F5 to the fourth resistor R72, and the current value can be sampled on the fourth resistor R72. Since the resistance of the fourth resistor R72 is very small, the voltage generated will not exceed 0.7V, so the second diode D12 is equivalent to having no effect when the signal is normal. After being amplified by 8 times by the isolation amplifier U18, the signal voltage is adjusted to the range of 0~3.3V after being conditioned by the sixth resistor R74, the seventh resistor R75, the eighth resistor R77 and the third diode D13. After being filtered by the seventh capacitor C83, the signal is output; at this time, the third diode D13 has no effect.

[0028] If the wires are connected incorrectly, when the high-voltage power supply is connected to the signal input terminal, the self-resetting fuse F5 will be heated by the large current and disconnect the protection. The large current will not continue to flow through the fourth resistor R72, and the fourth resistor R72 is protected. At the moment of wrong connection, the high voltage will be connected in series to the positive end of the second diode D12. Since the voltage is higher than 0.7V, the second diode D12 will be turned on instantly, clamping the voltage signal to 0.7V, and the input end of the isolation amplifier U18 will be protected. The isolation amplifier U18 can use a 2KV isolation element. Even if the high voltage is input to the input end of the amplifier, it will not be connected in series to the core circuit, and the core circuit is also protected.
