[0022] The installation environment requirements of the data acquisition controller are shown in Table 5: Table 5

[0023] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 2 , is a schematic diagram of an embodiment of a data acquisition and remote monitoring method based on a data acquisition controller in an embodiment of the present invention; the method is applied to an intelligent control box operation and maintenance platform, including: S201, in response to determining that a communication connection request sent by a data acquisition controller in a target area is received, configuring identification information for each data acquisition controller in the target area.

[0024] It is understandable that the execution subject of the present invention can be a data acquisition and remote monitoring method based on a data acquisition controller, or a PLC controller in an intelligent control box operation and maintenance platform, or a terminal or a server, which is not limited here. The embodiment of the present invention is described by taking a server as the execution subject as an example.

[0025] The target area can be a randomly selected area, for example, it can be a factory, a school, etc.; the number of data acquisition controllers can be one or more; each data acquisition controller can be connected to one or more terminal devices; the data acquisition controller and the terminal device are connected by line, and the data acquisition controller and the intelligent control box operation and maintenance platform are connected by communication; the above-mentioned identification information can be the number of the data acquisition controller, and each data acquisition controller has unique identification information.

[0026] Optionally, before the response to determining that a communication connection request sent by a data acquisition controller in the target area is received and configuring identification information for each data acquisition controller in the target area, the method also includes: determining the installation method and installation location information of the data acquisition controller according to the working environment information corresponding to the terminal device; based on the installation method, the installation location information and the interface model of the terminal device, selecting the corresponding interface on the data acquisition controller for connection; in response to determining that the connection is normal, generating a communication connection request, and sending the communication connection request to an intelligent control box operation and maintenance platform that is communicatively connected to the data acquisition controller, wherein the intelligent control box operation and maintenance platform includes a terminal display device and a PLC controller.

[0027] The above-mentioned terminal equipment includes at least one of the following: a controller, an intelligent circuit breaker, a temperature and humidity sensor, a water immersion detection device, a door lock, a power supply and a door magnet, etc.; the above-mentioned working environment information includes the temperature, humidity and other information of the environment where the above-mentioned terminal equipment is located; the above-mentioned installation methods include horizontal installation and non-horizontal installation, etc.; the installation location information can be used to describe the location information where the data acquisition controller can be installed; as an example, the data acquisition controller can be installed in four positions (i.e., installation directions): horizontal direction, vertical direction, top of the electric cabinet and bottom of the electric cabinet. It is recommended to be installed in the horizontal direction. Different installation positions have different requirements for working temperature and its restrictions; the best installation position is horizontal installation, and the heat dissipation design is through natural convection. In order to ensure normal ventilation and heat dissipation and reserve sufficient wiring space, the minimum gap must be retained around it; if there is high-temperature heat source equipment (heater, transformer, large resistor, etc.) in the surrounding area, at least 100mm of gap must be retained between the high-temperature heat source equipment. Different terminal devices select the corresponding port on the data acquisition controller for connection according to the interface model corresponding to the device; after determining that the connection is normal, a communication connection request is generated, and the communication connection request is sent to the intelligent control box operation and maintenance platform that is communicatively connected to the data acquisition controller, wherein the intelligent control box operation and maintenance platform includes a terminal display device and a PLC controller. The above-mentioned communication connection request may be a request initiated during the communication process, which aims to establish a communication link between the data acquisition controller and the intelligent control box operation and maintenance platform. The above-mentioned terminal display device may be a terminal device with display function such as a computer, mobile phone, tablet, etc.; the PLC controller may be a PLC (Programmable Logic Controller), which is a programmable logic controller, which is a digital computing and operating electronic system specially designed for industrial environment applications.

[0028] Optionally, before generating a communication connection request in response to determining that the connection is normal, and sending the communication connection request to an intelligent control box operation and maintenance platform that is communicatively connected to the data acquisition controller, the method also includes: determining a connection mode between the terminal display device and the PLC controller based on network operating environment information in the target area; enabling the PLC controller to access the terminal display device based on the determined connection mode; in response to determining that the access is successful, setting the IP address of the terminal display device on the terminal display device; in response to completion of the IP address setting, testing whether the connection between the terminal display device and the PLC controller is normal; in response to determining that the connection is normal, receiving a communication connection request sent by the data acquisition controller.

[0029] The above network operating environment information can be determined by the needs in the target area. The above connection method can be that the terminal display device and the PLC controller are directly connected, or it can be connected to a router or a switch, and the controller access is achieved by setting the router. As an example, the terminal display device is a computer; the controller is connected with a network cable, and the factory default IP address of this machine is 192.168.1.218. The computer accesses the controller, requiring the computer and PLC to be in the same LAN segment, and the wired network card (note that it is not a wireless network card) is set. The IP address is in the network segment of 192.168.1.XXX; after filling in the computer IP address, test whether the computer and PLC are physically connected normally, open the "Command Line Prompt" on the computer, enter ping192.168.1.218, and press Enter; in response to determining that the access is successful, the PLC returns data and the physical link is normal; the PLC can continue the following access. If the access is unsuccessful, check the computer settings until the ping is successful, and then the following application can be performed.

[0030] S202: Based on the identification information, obtain the real-time operation related information of the corresponding terminal device from each data acquisition controller.

[0031] The execution subject can obtain the real-time operation related information of the corresponding terminal device through each data acquisition controller, and correspond one by one with the identification information. The real-time operation related information can include whether the terminal device is currently in working state, and various data currently detected by the terminal device; S203: Determine the current working state of the terminal device based on the acquired real-time operation related information and the historical operation related information corresponding to the terminal device.

[0032] The above-mentioned execution subject can compare the real-time operation related information with the corresponding historical operation related information. If the operation related information is the same or similar under the same working state, then the current working state of the terminal device is normal, otherwise, the current working state of the terminal device is abnormal. As an example, if the operation related information is the same or similar under the same working state, because the working state of the terminal device refers to the terminal device being in working state and the terminal device not being in working state; the various data currently detected by the terminal device usually refer to input voltage, continuous voltage, etc.; when the working state of the terminal device corresponding to the real-time operation related information refers to the terminal device being in working state, the working state of the terminal device corresponding to the historical operation related information also refers to the terminal device being in working state, determine whether the input voltage and continuous voltage of the two terminal devices are the same or the error is within a certain range; if they are the same or the error is within a certain range, then the current working state of the terminal device is normal, otherwise, the current working state of the terminal device is abnormal. The above-mentioned certain range can be preset manually.

[0033] S204, in response to determining that the current working state is abnormal, generating device warning information, and sending the device warning information to the target terminal device.

[0034] The execution subject may generate device warning information when determining that the current working state of the terminal device is abnormal, and send the device warning information to the target terminal device. The device warning information may be information used to describe the device abnormality and the cause of the device abnormality, and the target terminal device may be a device carried by maintenance personnel or on-duty personnel.

[0035] Optionally, based on the identification information, current working information of each data acquisition controller is obtained, wherein the current working information includes the current working status of the data acquisition controller and the power supply information of the data acquisition controller; it is determined whether the current working status is consistent with the preset working status of the data acquisition controller; in response to determining that the working status is inconsistent, abnormal working information of the data acquisition controller is generated, and the abnormal working information of the data acquisition controller is sent to the target terminal device; based on the power supply information, it is determined whether the power supply of the data acquisition controller needs maintenance; in response to determining that the power supply needs maintenance, power supply maintenance information of the data acquisition controller is generated, and the power supply maintenance information of the data acquisition controller is sent to the target terminal device.

[0036] The above-mentioned current working state can be a working state and a dormant state. For example, when the terminal device is not working, we can remotely control the data acquisition controller to be in a dormant state; the power supply information of the data acquisition controller can be the power information of the battery of the data acquisition controller. In order to ensure that the data acquisition controller can still work in an unexpected situation, the data acquisition controller has its own battery, which can ensure that it can still work for 4-6 hours in the case of power failure, which gives the staff enough time for maintenance. Determine whether the current working state is consistent with the preset working state. If not, generate data acquisition controller work abnormality information, and send the data acquisition controller work abnormality information to the target terminal device; determine whether the power supply of the data acquisition controller needs maintenance according to the power supply information; determine that the power supply needs maintenance, generate data acquisition controller power supply maintenance information, and send the data acquisition controller power supply maintenance information to the target terminal device; under normal circumstances, the data acquisition controller will not use its own power supply. If the power supply is decreasing, it means that there is a problem with the connection power supply of the data acquisition controller and maintenance is required.

[0037] Optionally, in response to determining that the current working state is abnormal, generating equipment warning information, and sending the equipment warning information to the target terminal device, includes: obtaining location information of staff in the target area; in response to determining to generate equipment warning information, obtaining location information of terminal devices corresponding to the equipment warning information; determining the target staff based on the location information of the terminal device and the location information of the staff, and using the terminal device corresponding to the target staff as the target terminal device; and sending the equipment warning information to the target terminal device.

[0038] Because a factory cannot have only one maintenance personnel or on-duty personnel, and each maintenance personnel may work in different places during working hours, the intelligent control box operation and maintenance platform can determine the location information of the maintenance personnel based on the terminal device carried by each maintenance personnel; when determining to generate equipment warning information, determine the location information of the corresponding terminal device; determine the maintenance personnel who is closest to the terminal device at the current time based on the location information of the terminal device, and send equipment warning information to the terminal device carried by the maintenance personnel.

[0039] Optionally, the storage temperature range of the data acquisition controller is -20°C to +60°C; the storage relative humidity range is relative humidity <90%RH.

[0040] Optionally, the operating temperature range of the data acquisition controller is determined according to the installation method of the data acquisition controller, wherein the installation methods of the data acquisition controller include horizontal installation and non-horizontal installation; in response to determining that the installation method of the data acquisition controller is horizontal installation, the operating temperature range of the data acquisition controller is -20°C to +55°C; in response to determining that the installation method of the data acquisition controller is non-horizontal installation, the operating temperature range of the data acquisition controller is -20°C to +45°C.

[0041] Optionally, the data acquisition controller includes: 13 digital inputs, 2 analog inputs, 10 digital outputs, and 1 analog output; 1 network port; 24V power supply; 2 RS458 interfaces; the digital input port of the digital input uses a bidirectional optocoupler internally and supports NPN or PNP input; the analog input uses a high-precision AD and rail-to-rail op amp to achieve low voltage identification.

[0042] Adopting FLASH technology, no battery support is required, and the program is permanently saved; built-in emergency battery, in case of external power failure, the built-in battery can also be used for 4-6 hours; power reverse connection protection design; communication port electrostatic protection design; analog quantity short-circuit protection; the power board is made of solid materials and has sufficient power to meet the power supply of multiple expansions and sensors; it has undergone rigorous industrial field tests and environmental tests.

[0043] As an example, if the terminal device connected to the data acquisition controller is a door lock, the intelligent control box operation and maintenance platform can remotely open the door for the staff based on the staff's location information. If the terminal device connected to the data acquisition controller is a power supply, the intelligent control box operation and maintenance platform can remotely cut off the power.

[0044] In the embodiment of the present disclosure, the method is applied to the intelligent control box operation and maintenance platform, in response to determining that a communication connection request sent by a data acquisition controller in a target area is received, identification information is configured for each data acquisition controller in the target area; based on the identification information, real-time operation related information of the corresponding terminal device is obtained from each data acquisition controller; based on the obtained real-time operation related information and the historical operation related information corresponding to the terminal device, the current working state of the terminal device is determined; in response to determining that the current working state is abnormal, device warning information is generated, and the device warning information is sent to the target terminal device.
