[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0022] like Figure 1 - Figure 3 As shown, this embodiment provides a smoke and high temperature alarm device for an intelligent salt spray chamber, including a smoke and high temperature alarm component 9 for limiting the position of the equipment;

[0023] A temperature sensor 1 6 is installed in the smoke and high temperature alarm component 9, and a temperature sensor 2 8 is installed on both sides of the temperature sensor 1 6. Smoke sensor 2 2 and smoke sensor 1 1 are installed at the openings on both sides of the smoke and high temperature alarm component 9. Smoke sensor 3 5 and smoke sensor 4 7 are installed at the diagonally opposite corners of smoke sensor 1 1 and smoke sensor 2 2. An integrated alarm module 3 and a temperature transmitter 4 are installed on one side of the temperature sensor 6.

[0024] Smoke sensor 1 1 , smoke sensor 2 2 , smoke sensor 3 5 and smoke sensor 4 7 detect the smoke concentration in the smoke and high temperature alarm component 9 .

[0025] Temperature sensor 1 6 and temperature sensor 2 8 are attached to the inner wall of the smoke and high temperature alarm component 9.

[0026] The temperature transmitter 4 converts the signal and transmits it to the integrated alarm module 3.

[0027] The inner side of the smoke and high temperature alarm component 9 is a through-type structure.

[0028] The temperature sensor 2 8 on the temperature sensor 1 6 is a symmetrical installation structure.

[0029] like Figure 1 - Figure 3 As shown, the working process of the smoke and high temperature alarm device of the intelligent salt spray chamber provided in this embodiment is as follows: smoke sensor 1, smoke sensor 2, smoke sensor 3, smoke sensor 5, and smoke sensor 4 7 use high-sensitivity smoke sensors. The smoke sensors transmit analog signals to the MCU, which can monitor the changes in smoke concentration inside the salt spray chamber in real time;

[0030] Temperature sensor 1 6 and temperature sensor 2 8 use high-precision PT100 temperature sensors. PT100 is attached to the inner wall of the salt spray chamber to monitor the temperature of the inner wall of the salt spray chamber and detect the occurrence of high temperature conditions.

[0031] Temperature transmitter 4 is a temperature transmitter. The PT100 signal is first converted into a 4-20ma current signal through the transmitter, and this signal is transmitted to the integrated alarm module 3. The integrated alarm module makes an alarm action based on the collected smoke concentration and temperature. At the same time, the GSM module on the integrated alarm module will automatically send the alarm information to the mobile phone of the person in charge of the equipment.

[0032] Example

[0033] like Figure 1 - Figure 3 As shown, smoke sensor 1 and smoke sensor 2 are respectively installed at the corners on both sides of the smoke and high temperature alarm component 9, a temperature sensor 1 is installed inside the smoke and high temperature alarm component 9, an integrated alarm module 3 and a temperature transmitter 4 are respectively installed on the outside of the temperature sensor 1 6, a smoke sensor 3 5 and a smoke sensor 4 7 are installed at the diagonally opposite corners of the smoke sensor 2 2 and the smoke sensor 1, and a temperature sensor 2 8 is installed on the outside of the temperature sensor 1 6;

[0034] Smoke sensor 1, smoke sensor 2, smoke sensor 3, smoke sensor 5, and smoke sensor 4, smoke sensor 7, use high-sensitivity smoke sensors. The smoke sensors transmit analog signals to the MCU, which can monitor the changes in smoke concentration inside the salt spray chamber in real time.

[0035] Figure 1 The middle temperature sensor 6 and the temperature sensor 2 8 use high-precision PT100 temperature sensors. The PT100 is attached to the inner wall of the salt spray chamber to monitor the temperature of the inner wall of the salt spray chamber and detect the occurrence of high temperature conditions.

[0036] Temperature transmitter 4 is a temperature transmitter. The PT100 signal is first converted into a 4-20ma current signal through the transmitter, and this signal is transmitted to the integrated alarm module 3. The integrated alarm module 3 generates an alarm action based on the collected smoke concentration and temperature. At the same time, the GSM module on the integrated alarm module 3 will automatically send the alarm information to the mobile phone of the person in charge of the equipment.

[0037] An independent 24V DC power supply is connected to the integrated circuit module, and the voltage regulator circuit outputs stable 5V and 3.3V voltages to power the sensor and MCU.

[0038] The four smoke sensors output analog signals to the integrated alarm module 3 through the conversion circuit. The MCU in the integrated alarm module 3 collects the smoke concentration through AD conversion and is used to monitor the smoke concentration in various parts of the salt spray chamber.

[0039] The two PT100s first output a 4-20ma current signal through a temperature transmitter to the integrated alarm module 3, which converts the current signal into a voltage signal. The MCU then collects the temperature through AD conversion to monitor the temperature of the inner wall of the salt spray chamber.

[0040] The integrated alarm module 3 includes an OLED module that can display the collected smoke concentration and temperature on the OLED display screen, making it convenient for users to check at any time;

[0041] The GSM module integrated in the integrated alarm module 3 can send alarm information to the mobile phone of the person in charge of the equipment when the system detects abnormal smoke concentration or temperature, ensuring that the person in charge is aware of the alarm status of the equipment in a timely manner;

[0042] In the integrated alarm module 3, when the system detects abnormal smoke concentration or temperature, a relay in the integrated alarm module 3 will output a signal, which can be converted to the PLC main control of the salt spray chamber so that the salt spray chamber can also respond in time;

[0043] In the integrated alarm module 3, when the system detects that the smoke concentration or temperature is abnormal, a relay in the integrated alarm module 3 will output to the sound and light alarm to generate a sound and light alarm.

[0044] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present invention within the scope disclosed by the present invention, which falls within the protection scope of the present invention.
