[0030] The technical solution provided by the present invention will be described in detail below in conjunction with specific embodiments. It should be understood that the following specific implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0031] The external structure of the intelligent data acquisition device for dam safety monitoring with active protection provided by the utility model is as follows: Figure 1-Figure 3As shown, the data acquisition device comprises a box 1, a box cover 2 is provided on the box 1, and a plurality of waterproof joints 3 are provided at the bottom of the box 1. The waterproof joints 3 are connected to the internal components of the box 1 and are used for quick plugging with peripherals. The door magnetic switch slave sensor 4 and the door magnetic switch master sensor 5 are respectively installed on the box cover 2 and the box 1. The master sensor and the slave sensor are used to open and close the box cover, and can monitor and record the opening and closing of the door. The four corners of the box are provided with mounting parts 6, and screw holes are provided on the mounting parts. The box can be installed on other structures by using the mounting parts 6 in combination with bolts.

[0032] like Figure 4 As shown, the data acquisition device box is divided into four layers, which are respectively a power supply layer 7, a communication layer 8, a data acquisition layer 9, and a lightning protection layer 10 from top to bottom, and the layers are separated by fireproof partitions 11.

[0033] A smart socket 12 is installed in the power supply layer. The smart socket has its own wireless transmission communication component, which can remotely control the power on and off of the smart socket. In this example, the model of the smart socket is GN-Y2012. The power supply layer is also equipped with a power module 13, which converts 220V AC into 12V AC. The power module is equipped with a surge protector to prevent damage from power current surges. The power module 13 is inserted into the smart socket. In this example, the power model is CJ60TZ, which has voltage reduction and surge protection functions. The power supply layer is also equipped with a smoke alarm 14, which can monitor whether there is combustion in the box. In this example, the alarm model is NP-Y1-S. The power module supplies power to various components in the data acquisition device.

[0034] The communication layer is equipped with an intelligent gateway 15 and a GPRS 4G communication module 16. The intelligent gateway 15 is used to connect the devices in the data acquisition device through wireless networking. The GPRS 4G communication module 16 is used to connect the intelligent gateway to the public network, upload data to the cloud server, display data on the mobile terminal and PC, and realize remote operation. The GPRS 4G communication module 16 is connected to the antenna 22. The antenna is installed on the top surface of the box. In this example, the model of the intelligent gateway is DMWG03LM; the model of the GPSR 4G module is H7710C.

[0035] The data acquisition layer is equipped with a data acquisition unit 17 and a temperature and humidity sensor 18. The data acquisition unit 17 is used to collect monitoring data. In this example, the data acquisition unit model is G16M. The temperature and humidity sensor 18 monitors the temperature and humidity of the data acquisition layer. In this example, the model is XMWSDJ04MMC. The temperature and humidity sensor is fixed at the bottom of the upper fireproof partition and can sense the burning danger of the communication layer as quickly as possible.

[0036] The lightning protection layer is equipped with a lightning protection channel plate 19 and a water immersion sensor 20. The lightning protection channel plate 19 is connected to the data acquisition unit 17 through a communication flat cable 21 to achieve signal transmission, which can prevent lightning surges from entering the data acquisition device from the monitoring instrument cable and avoid damaging the data acquisition unit 17. Figure 5 , Figure 6 As shown, a set of lightning protection channel panels is composed of a lightning protection channel bottom plate 19-1 and a plurality of lightning protection small plug-in boards 19-2. Figure 5 , Figure 6 As shown, a set of lightning protection channel boards consists of 1, and a plurality of slots 19-3 are arranged on the bottom plate of the lightning protection channel, and the small lightning protection plug board 19-2 is plugged into the slot for easy plug-in and replacement. Each small lightning protection plug board is connected to two slots of the bottom plate of the lightning protection channel. When a lightning surge enters the data acquisition device through a certain channel, it will only damage the small lightning protection plug board of the channel. An instrument terminal 19-4 is arranged at one end of the bottom plate 19-1 of the lightning protection channel. The instrument terminal 19-4 is connected to the waterproof connector at the bottom of the box 1 through a signal cable, and the waterproof connector is connected to the external safety monitoring instrument through a signal cable. The water immersion sensor 20 is used to monitor whether the box of the data acquisition device has water ingress. It is installed at the bottom of the box. Since water always flows downward, the water immersion sensor can collect data as soon as possible when water enters the box. The water immersion sensor and the intelligent gateway are Zigbee networked.

[0037] The connection relationship between the components in the data acquisition device box is as follows Figure 7 The power supply is used for the smoke alarm, smart socket, door magnetic switch, data acquisition unit, water immersion sensor, and temperature and humidity sensor. The smart gateway uses Zigbee to wirelessly network the data acquisition unit, water immersion sensor, temperature and humidity sensor, smoke alarm, smart socket, and door magnetic switch.

[0038] The working principle of the utility model is as follows:

[0039] In the normal operation state of the intelligent data acquisition device for dam safety monitoring with active protection provided by the utility model, the data acquisition unit collects monitoring data and sends it to the cloud through the GPRS 4G communication module. The temperature and humidity sensor monitors the temperature and humidity in the data acquisition device in real time. The temperature and humidity sensor and the intelligent gateway are networked with Zigbee. The temperature and humidity warning values ​​can be set on the mobile terminal or PC terminal. When the temperature and humidity values ​​in the data acquisition device reach the warning value, a reminder is issued. The door magnetic switch will record the opening and closing status of the door of the data acquisition device and monitor the current closing status of the door. The door magnetic switch and the intelligent gateway are networked with Zigbee. The opening and closing status of the door will be transmitted to the cloud server through the intelligent gateway and the GPRS 4G communication module; if the door is not closed for a long time, a reminder will be issued. The function of judging the closing reminder of the door is a simple program and does not require innovative improvements.

[0040] When dangerous events such as fire, flooding, lightning strike, etc. occur, the utility model can effectively deal with them:

[0041] When encountering thunderstorms, the induced current caused by lightning strikes will enter the data acquisition device along the cable. The lightning protection channel board plays a good protective role, and the surge protector will cut off the induced current to ensure the safe operation of the data acquisition unit. When a flooding accident occurs outside the data acquisition device and the water floods to the bottom of the box, the water immersion sensor alarm will be triggered. The water immersion sensor and the smart gateway are networked with Zigbee. The alarm information will be transmitted to the cloud server through the smart gateway and GPRS 4G communication module to issue a reminder. When combustion occurs in the data acquisition device and smoke is generated, the smoke alarm will be triggered. The smoke alarm and the smart gateway are networked with Zigbee. The alarm information will be transmitted to the cloud server through the smart gateway and GPRS 4G communication module to issue a reminder. The smart socket and the smart gateway are networked with Zigbee. The smart socket can be connected to the mobile terminal or PC through the smart gateway and GPRS 4G module. The manager can remotely control the on and off of the socket power supply. When adverse environments such as thunderstorms, flooding alarms, and burning alarms occur, the socket power supply can be remotely cut off. It should be noted that the threshold judgment, data collection, remote signal transmission, reminder issuance, power control on and off, etc. applied in the utility model are all simple programs or built-in programs in smart devices, and no software improvement is required.

[0042] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
