Detailed ways

The invention provides a function configuration method of a gas detector and a system thereof. By adding a repeater function (data conversion) to the gas detector, the gas detector can perform three functions (gas detection function, gas detection + data Forwarding function, data forwarding function) can be switched arbitrarily without adding repeaters, which avoids the increase of power consumption. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

Please refer to FIG. 1, the function configuration method of the gas detector provided by the present invention includes:

S100. Configure the device type of the gas detector, and select whether to add the repeater function;

S200, switching between the detection relay function and the relay function according to the disconnection state between the gas detector and the sensor;

S300, the gas detector with repeater function transmits the gas concentration data of other gas detectors to the gas alarm control host.

In this embodiment, by choosing whether to add the repeater function, the gas detector can only maintain the existing gas detection function (that is, the gas detector is only used as a gas detector, and the gas concentration data of the sensor is collected and sent to the gas alarm control host) or increase the repeater function; further select whether it is compatible with the gas detection function and the repeater function at the same time through the disconnection state of the sensor (that is, the gas detector can be used as a gas detector and a repeater at the same time, collecting the sensor Whether the data is sent to the gas alarm control host, and the gas concentration data is forwarded to other devices in the same network (gas detector or gas alarm control host)), or only has the repeater function (that is, the gas detector is used as a repeater) , does not collect the gas concentration data of the sensor, but can only receive the gas concentration data transmitted by other gas detectors and forward it to other devices in the same network).

In this embodiment, the step S100 specifically includes:

Step 110 , when it is detected that the input code key is pressed under the standard interface of the gas detector, the password input interface is entered.

In this step, the gas detector (full name is online wireless gas detector) directly displays the standard interface after it is turned on. Press the input key in this standard interface to enter the password input interface. The code input key is composed of the existing "OK" key and the "M" key on the gas detector. Simultaneously long press the "OK" key and the "M" key to enter the password input interface.

Step 120: Enter the type configuration interface after judging that the inputted password is correct, and configure the corresponding device type according to the inputted parameters.

In this step, first determine whether the entered password is correct, for example, enter the password 1111, and enter the type configuration interface after being correct. Password input can prevent others from tampering with the function of the gas detector and affect the overall work of the system.

In the type configuration interface displayed on the display screen of the gas detector, TP is displayed on the left to indicate that it is an abbreviation of type, and the right side shows the parameters corresponding to a certain type. In this embodiment, the device type corresponding to each parameter is preset. For example, when the parameter is 00, it means that the device type is a gas detector. At this time, the repeater function (the function of the repeater, that is, the data forwarding function) is not added. It has the function of a gas detector; when the parameter is 01, it means that the device type is a dual device, that is, a gas detector + repeater, and the repeater function is added. At this time, it has the functions of a gas detector and a repeater. Enter the corresponding device type by entering the corresponding parameters.

Step 130 , when the detection device type is dual device, configure the ZigBee module in routing mode to increase the repeater function.

In this step, if the parameter detected by the MCU in the gas detector is 01, it means that the repeater function is added to the gas detector. At this time, the MCU sends a configuration command to the ZigBee module, and the ZigBee module can be configured in routing mode. The ZigBee module model is preferably ZM32P2S24E from Zhiyuan Electronics.

The advantage of the ZigBee module is that it still has all the functions of the terminal device (which can receive wireless data and send wireless data) when it is in the routing mode (that is, it has the function of a repeater and can forward data). It is equivalent to integrating the repeater with the gas detector. When the module is arranged on site, the type of ZigBee module can be flexibly set according to the requirements. After this configuration, the gas detector not only has the existing gas detection function, but also has the repeater function (that is, it can receive the data sent by other gas detectors and wirelessly transmit it to the gas alarm control host 6).

It should be understood that the configuration in step S100 is to determine whether to add a repeater function to the gas detector by inputting parameters. After the addition, whether to use the repeater function in the subsequent specific application process, that is, whether to coexist with the gas detection function or to have the repeater function alone, also needs to be realized through the configuration of step S200. The step S200 specifically includes:

Step 210 , enter the mode configuration interface, and input corresponding parameters to set the disconnection state between the gas detector and the sensor.

In this step, on the type configuration interface, the mode configuration interface can be entered by using the infrared remote control to click the up key or the down key. Enter the corresponding parameters in the mode configuration interface to choose whether to connect the sensor.

Step 220 , when the detection gas detector is connected to the sensor, the gas detector is switched to the detection relay function; when the detection gas detector is not connected to the sensor, the gas detector is switched to the relay function.

If the repeater function has been configured in the above step S100, enter 01 on the mode configuration interface (displayed on the right), then the gas detector is set to connect to the sensor, and the gas detector can receive the gas concentration value detected by the sensor and The display is also compatible with the data forwarding function of the repeater, that is, the gas detector is configured to detect the repeater function (gas detector + repeater); the gas concentration is displayed on the left side of the mode configuration interface. Enter 00 on the mode configuration interface, then the gas detector is not connected to the sensor, and the gas detector will not receive the value transmitted by the sensor. At this time, the gas detector is only used as a repeater, on the left side of the mode configuration interface. "-rly-" is displayed. If "-rly-" is displayed as a repeater only, it can ensure that the gas detector can be easily converted to a repeater-only mode, because the device will alarm (sensor failure) when the sensor is not connected, but it is configured as a repeater only. There will be no false alarms after the controller mode is activated.

If the configuration device type in the above step S100 is a gas detector and there is no repeater function, even if 01 is input in this step, the gas detector is set to connect to the sensor, but the gas detector can only receive the gas concentration value detected by the sensor. And display, that has all the functions of existing gas detectors. If you mistakenly input 00 on the mode configuration interface, when the gas detector is not connected to the sensor, because the previous setting does not have the repeater function, it means that the setting is faulty, and the left side of the mode configuration interface displays garbled characters or "error" to prompt The user's parameter input is wrong, thus indirectly prompting the user that the repeater function has not been added before.

It should be noted that, in step S100, 00 and 01 input in the type configuration interface indicate whether to add a repeater function. In step S200, 00 and 01 input in the mode configuration interface indicate whether the sensor is connected. Through the parameter input of different interfaces, the required type of gas detector can be configured on demand, which greatly improves the flexibility of equipment networking, breaks through the limitations of the site, and saves the work of site survey before shipment.

In the specific implementation, when 01 is input on the MCU detection mode configuration interface, it can judge whether the sensor has been connected according to the level signal on the detection pin of the interface connected with the sensor, such as high level means the sensor is connected, low level Level or floating means not connected. If it is judged to be connected at this time, the gas detector works normally; if it is not connected, the MCU alarms. Similarly, when 00 is input on the mode configuration interface, the detection pin is normally low and not connected; if the detection pin becomes high in other circumstances, the MCU will alarm.

As shown in FIG. 2, the first gas detector 1 and the third gas detector 3 are too far away from the gas alarm control host 6, and the fifth gas detector 5 is placed in a position where the first gas detector 1 and the third gas detector can be received. The signals of the three gas detectors 3, therefore, the fifth gas detector 5 can be configured as a dual device type (that is, compatible with the gas detection function and the repeater function), so that the first gas detector 1 and the third gas detector 3 The collected gas concentration data can be forwarded to the gas alarm control host 6 through the fifth gas detector 5 ; the gas concentration data collected by the fifth gas detector 5 can also be directly sent to the gas alarm control host 6 . The second gas detector 2 is far away from the gas alarm control host 6 and the fifth gas detector 5, and no other equipment is placed in the middle. At this time, a fourth gas detector 4 without a gas sensor can be placed, and the It is configured as a repeater (only has repeater function), which can transmit the data of the second gas detector 2 to the gas alarm control host 6; when there is a need for subsequent gas detection, it can also be directly connected to the fourth gas detector. Install sensors in 4 (all sensors in this embodiment are gas sensors). This makes network deployment more convenient, without adding repeaters, avoiding the increase in power consumption, and can arbitrarily adjust type functions to meet different work requirements.

Based on the above-mentioned function configuration method of a gas detector, an embodiment of the present invention further provides a function configuration system for a gas detector. Please continue to refer to FIG. 2 . The function configuration system includes a gas alarm control host 6 and several gas detectors. (1-5); the gas detector configures the device type, and selects whether to add a repeater function; switches between the detection relay function and the relay function according to the disconnection state of the gas detector and the sensor; has a repeater The functional gas detector transmits the gas concentration data of other gas detectors to the gas alarm control host. The gas alarm control host can detect the air quality of the corresponding area according to the gas concentration data, and give an alarm prompt when a certain gas exceeds the standard.

To sum up, the function configuration method and system of the gas detector provided by the present invention are aimed at the problem that the existing repeater only has the function of forwarding data and the increase of the repeater in wireless communication leads to an increase in power consumption. The ZigBee module is added to the detector to choose whether to add the data forwarding function. Combined with whether to connect the sensor, the gas detector can be switched arbitrarily under the three functions (gas detection function, gas detection + data forwarding function, data forwarding function). Using the gas detector as a repeater, there is no need to add an additional repeater during wireless communication, avoiding the power consumption caused by the repeater; it will not affect the existing gas detection function.

The division of the above-mentioned functional modules is only for illustration. In practical applications, the above-mentioned functions can be allocated to different functional modules according to needs, that is, divided into different functional modules to complete all or part of the functions described above.

It can be understood that for those of ordinary skill in the art, equivalent replacements or changes can be made according to the technical solutions of the present invention and the inventive concept thereof, and all these changes or replacements should belong to the protection scope of the appended claims of the present invention.
