All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a fire-fighting internet of things signal analog transmission system includes: the system comprises a signal simulation module 1, a signal processing module 2, a communication module 3, a user information transmission device 4 and a simulation cloud platform 5.
The signal simulation module 1 is signal simulation software on a computer, namely a PC, is integrated with various alarm signals of fire alarm controllers of various brands in the prior art, and is used for simulating various alarm signals of the fire alarm controllers of various brands and simulating various alarm signals of the fire alarm controllers of various brands.

The user selects a certain alarm signal of a certain brand of fire alarm controller through the signal simulation module 1, and the signal simulation module 1 sends the alarm signal to the signal processing module 2.
The signal processing module 2 comprises a single chip 21 and a level conversion chip 22. Wherein, the singlechip 21 is an MCS-51 singlechip; the level shift chip 22 is a max232 chip.
After receiving the alarm signal, the single chip microcomputer 21 firstly converts the data format of the alarm signal, and converts the alarm signal into data in a standard format according to a unified standard, wherein the unified standard can be customized according to GBT 26875.3; the GBT 26875.3 defines a protocol structure, a data type and a data definition for data transmission between a user information transmission device and a monitoring center in the urban fire-fighting remote monitoring system through an alarm transmission network. After the data format conversion is completed, the single chip microcomputer 21 encrypts the standard format data to obtain the encrypted standard format data. The single chip microcomputer 21 sends the encrypted data in the standard format to the communication module 3.
When the single chip 21 communicates with the communication module 3 through a serial port, although the single chip 21 has a serial communication function, a signal level provided by the single chip 21 is different from a standard of an RS232 interface on the communication module 3, and therefore, level conversion needs to be performed through the level conversion chip 22. The max232 chip is a single power level conversion chip specially designed for an RS232 standard serial port and is used for performing bidirectional level conversion between TTL and EIA; through level conversion, the single chip microcomputer 21 is ensured to send the encrypted standard format data to the communication module 3.
Similarly, since the signal simulation module 1 is signal simulation software on a PC, the above problem also exists when the single chip microcomputer 21 communicates with the signal simulation module 1 through a serial port, and therefore, the max232 chip is also used for performing level conversion required when the single chip microcomputer 21 communicates with the signal simulation module 1.

In the invention, a real user information transmission device 4 is selected, namely the existing user information transmission device 4 is directly applied to the fire-fighting Internet of things signal simulation transmission system, because the communication protocols and the corresponding interfaces of the fire alarm controllers of different brands are different, the user information transmission device 4 needs to be firstly selected, the user information transmission device 4 is selected according to the communication protocol and the corresponding interface of the fire alarm controller of the brand selected by a user, the user information transmission device 4 capable of being in butt joint with the communication protocol and the corresponding interface is selected, and after the selection is finished, the user information transmission device 4 is configured according to the installation setting specification of the selected user information transmission device 4, and the local IP, the local port, the target IP, the target port and the user code of the user information transmission device 4 are configured, And (4) communication protocol.
After the model selection and configuration are completed, the user information transmission device 4 can receive the standard format data sent by the communication module 3, and after the standard format data are received, the user information transmission device 4 sends the standard format data to the simulation cloud platform 5 through a network.
The simulated cloud platform 5 is test software on a computer, performs data format conversion on standard format data according to the same unified standard as the signal processing module 2, and converts the standard format data into an original signal, namely an alarm signal of the fire alarm controller.
The detection method for the data communication condition between the user information transmission 4 and the fire alarm controllers of various brand types by using the invention comprises the following steps: firstly, the brand, the communication protocol, the communication interface and the model of the user information transmission device 4 of the fire alarm are kept in one-to-one correspondence, and when the alarm signal sent out by the signal simulation module 1 is the same as the alarm signal obtained by the simulation cloud platform 5, the data communication between the user information transmission device 4 and the fire alarm controller of the brand is normal.
