It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0069] Embodiment 1

[0070] Figure 1 This is a flow chart of a method for identifying a gas appliance exhaust detection device provided by an embodiment of the present invention. This embodiment is applicable to situations where the method can be performed by a gas appliance exhaust detection device identification device provided by an embodiment of the present invention. The device can be implemented by software and / or hardware and is usually configured in an electronic device, such as Figure 1 As shown, the gas appliance exhaust detection device identification method specifically includes the following steps:

[0071] S101. When the gas appliance is powered on for the first time, control the fan of the gas appliance to run at a preset speed.

[0072] In the embodiment of the present invention, the gas appliance may be a gas water heater, a wall-mounted boiler, or other device having a flue and equipped with a fan and an exhaust detection device, which is not limited in the embodiment of the present invention. When the gas appliance is powered on for the first time (for example, the first power-on debugging before leaving the factory), the fan of the gas appliance is controlled to run at a preset speed.

[0073] S102, obtaining a detection signal sent back by the exhaust gas detection device, and if the detection signal meets a preset condition, determining that the exhaust gas detection device is a wind pressure type detection device.

[0074] During the operation of the fan, the detection signal transmitted back by the exhaust detection device is obtained. If the detection signal meets the preset conditions, the exhaust detection device is determined to be a wind pressure type detection device, wherein the preset conditions include that the detection signal is a pulse signal or the state of the detection signal is reversed. The wind pressure type detection device may include a wind pressure switch and a wind pressure sensor. The wind pressure switch is activated when the wind pressure in the flue is lower than the wind pressure threshold, so that the gas appliance is shut down. The wind pressure sensor is used to collect the wind pressure in the flue and feed it back to the controller of the gas appliance. When the wind pressure in the flue is lower than the wind pressure threshold, the controller issues a shutdown command. Exemplarily, the detection signal transmitted back by the wind pressure sensor is a pulse signal, so it can be determined whether the exhaust detection device is a wind pressure sensor based on this. The state of the detection signal transmitted back by the wind pressure switch when the wind pressure in the flue is lower than the wind pressure threshold and when the wind pressure in the flue is higher than the wind pressure threshold will be reversed, so it can be determined whether the exhaust detection device is a wind pressure switch based on this. The wind pressure in the flue is related to the speed of the fan. Therefore, in an embodiment of the present invention, the preset speed needs to be greater than the critical speed corresponding to the wind pressure threshold.

[0075] S103: If the detection signal does not meet the preset conditions, it is determined that the exhaust gas detection device is a temperature control type detection device.

[0076] If the detection signal does not meet the preset conditions, it is determined that the exhaust detection device is a temperature-controlled detection device. The temperature-controlled detection device may include a switch-type thermostat and a thermistor-type thermostat. The switch-type thermostat is activated when the temperature in the flue reaches a temperature threshold, causing the gas appliance to shut down. The thermistor-type thermostat is used to collect the temperature in the flue and feed it back to the controller of the gas appliance. When the temperature in the flue reaches the temperature threshold, the controller issues a shutdown command. Exemplarily, if the detection signal is neither a pulse signal, and the state of the detection signal sent back by the wind pressure switch when the wind pressure in the flue is lower than the wind pressure threshold and when the wind pressure in the flue is higher than the wind pressure threshold does not flip, it can be determined that the exhaust detection device is a temperature-controlled detection device.

[0077] The method for identifying the exhaust detection device of a gas appliance provided in an embodiment of the present invention controls the fan of the gas appliance to run at a preset speed when the gas appliance is powered on for the first time, obtains a detection signal sent back by the exhaust detection device, and if the detection signal meets preset conditions, determines that the exhaust detection device is a wind pressure type detection device. The preset conditions include that the detection signal is a pulse signal or the state of the detection signal is reversed. If the detection signal does not meet the preset conditions, determines that the exhaust detection device is a temperature control type detection device. The method can automatically identify the type of the exhaust detection device based on the detection signal sent back by the exhaust detection device, thereby providing convenience for subsequent program debugging and maintenance and reducing debugging and maintenance costs.

[0101] For example, as described above, the state of the detection signal sent back by the wind pressure switch when the wind pressure in the flue is lower than the wind pressure threshold and when the wind pressure in the flue is higher than the wind pressure threshold will flip. Then, if the first state information and the second state information of the detection signal before and after the fan stops are flipped, it can be determined that the exhaust detection device is a wind pressure switch. If the first state information and the second state information of the detection signal before and after the fan stops are not flipped, it can be determined that the exhaust detection device is a temperature control detection device.

[0130] S501. When the gas appliance is powered on for the first time, control the fan of the gas appliance to run at a preset speed.

[0131] In the embodiment of the present invention, the gas appliance may be a gas water heater, a wall-mounted boiler, or other device having a flue and equipped with a fan and an exhaust detection device, which is not limited in the embodiment of the present invention. When the gas appliance is powered on for the first time (for example, the first power-on debugging before leaving the factory), the fan of the gas appliance is controlled to run at a preset speed.

[0132] S502: Acquire a detection signal sent back by the exhaust gas detection device. If the detection signal meets a preset condition, determine that the exhaust gas detection device is a wind pressure type detection device.

[0133] During the operation of the fan, the detection signal transmitted back by the exhaust detection device is obtained. If the detection signal meets the preset conditions, the exhaust detection device is determined to be a wind pressure type detection device, wherein the preset conditions include that the detection signal is a pulse signal or the state of the detection signal is reversed. The wind pressure type detection device may include a wind pressure switch and a wind pressure sensor. The wind pressure switch is activated when the wind pressure in the flue is lower than the wind pressure threshold, so that the gas appliance is shut down. The wind pressure sensor is used to collect the wind pressure in the flue and feed it back to the controller of the gas appliance. When the wind pressure in the flue is lower than the wind pressure threshold, the controller issues a shutdown command. Exemplarily, the detection signal transmitted back by the wind pressure sensor is a pulse signal, so it can be determined whether the exhaust detection device is a wind pressure sensor based on this. The state of the detection signal transmitted back by the wind pressure switch when the wind pressure in the flue is lower than the wind pressure threshold and when the wind pressure in the flue is higher than the wind pressure threshold will be reversed, so it can be determined whether the exhaust detection device is a wind pressure switch based on this. The wind pressure in the flue is related to the speed of the fan. Therefore, in an embodiment of the present invention, the preset speed needs to be greater than the critical speed corresponding to the wind pressure threshold.

[0134] S503: If the detection signal does not meet the preset condition, control the gas appliance to ignite and burn, and maintain the second preset time.

[0135] S504: Acquire the detection signal sent back by the exhaust gas detection device.

[0136] During the combustion process of the gas appliance, the detection signal sent back by the exhaust detection device is obtained.

[0137] S505: Determine whether the voltage value of the detection signal acquired within the second preset time period changes.

[0138] For example, during the combustion process of the gas appliance, as the high-temperature flue gas is continuously discharged, the temperature in the flue will continue to rise within the second preset time period. If the exhaust detection device is a thermistor type thermostat, the detection signal it sends back is an analog signal, and the analog voltage value of the analog signal will change (for example, continue to increase). Therefore, it can be determined based on this whether the exhaust detection device is a thermistor type thermostat.

[0240] The existing solution is to design a hardware circuit for each exhaust detection device separately and adapt the corresponding driver, which results in the inability to unify and standardize the products, and there are many types of materials, which increases the material cost and management difficulty. The present invention can integrate multiple sets of hardware circuits and multiple sets of driver programs into one control board, automatically identify the type of exhaust detection device based on the detection signal returned by the exhaust detection device, and select the hardware circuit and driver program that are adapted to the judgment result, and then drive the corresponding exhaust detection device, so as to achieve product unification and standardization, and reduce material cost and management difficulty.

[0241] In the aforementioned embodiment, after obtaining the judgment result of the gas appliance exhaust detection device, the judgment result is uploaded to the after-sales service platform. When a failure occurs in the exhaust detection device, the after-sales service platform sends the identification result to the maintenance personnel's terminal so that the maintenance personnel can carry an appropriate exhaust detection device for replacement and carry appropriate maintenance tools, thereby reducing after-sales costs.
