Detailed Description
As shown in fig. 1 and 2, the water leakage monitoring device 1 of the present invention includes a water absorption module 105, a sensing module 106, a microprocessor module 101, and a water leakage signal operation module. The water leakage monitoring device can be used independently or simultaneously with a corresponding water leakage protection mechanism. When the water leakage alarm device is used independently, the water leakage signal action module adopts an alarm module 107; when the water leakage protection device is used together with a mechanism for performing water leakage protection by closing the valve, the water leakage signal action module can adopt the signal transmitting module 105 alone or the combination of the signal transmitting module 105 and the alarm module 107. When the water leakage monitoring device 1 is used alone, when water leakage is detected, the alarm module 107 gives an alarm. When people receive the alarm signal, the valve on the main pipeline can be manually closed, and then the water leakage position is treated. The implementation mode can help users who are inconvenient to install the control valve opening and closing executing mechanism on the main pipeline, and the users can be reminded in time to carry out emergency treatment. The disadvantage of using a single pump is that if the user does not find and close the valve on the main pipe in time, the water leak will continue. When the water leakage protection device is used with an actuating mechanism for performing water leakage protection by closing the valve, the signal transmitting module 105 transmits a corresponding control signal to the actuating mechanism arranged on the main pipeline to close the valve for performing water leakage protection. The water leakage monitoring device 1 is in wireless communication connection with the actuating mechanism, so that the water leakage monitoring device 1 can be placed in any places where power lines and signal lines are inconvenient to arrange.
As shown in fig. 1 and 2, the sensing module 106, the microprocessor module 101, the power module 102, the signal transmitting module 104, the signal matching/testing module 103 and the alarm module 107 are mounted on the PCB between the lower cover 15 and the upper cover 17, and the fixing base 11 is screwed on the lower cover 15. In the present embodiment, the expansion body 12 is used as the water absorption module 105. When the water leakage monitoring device 1 is in a standby state, the expansion body 12 is in a compressed state, and the whole water leakage monitoring device 1 is in a power-off state, so that standby zero power consumption is realized. When the expansion body 12 is contacted with water leakage, the expansion body rapidly expands (mechanically triggers to ensure zero power consumption in a standby state), the triggering induction module 106 is switched on, the power supply module 102 and other modules form a conduction loop to start working, the water leakage monitoring device 1 is changed from a power-off state to a power-on state, the microprocessor module 101 starts power-on working, a signal is transmitted to the execution mechanism through the signal transmission module 104, and meanwhile the alarm module 107 starts alarming. In this embodiment, the sensing module 106 may be a pressure switch or a clarinet, or may be other mechanical trigger structures that do not require power supply, and such a conversion is within the protection scope of the present application. The water leakage monitoring device 1 usually needs to be used in conjunction with an actuator, when the water leakage monitoring device 1 detects water leakage, the signal transmitting module 104 transmits a signal, and the actuator receives the signal and automatically closes a valve on a main pipeline. Meanwhile, the alarm module 107 sends out an alarm signal, so that when the user receives the alarm signal, the water leakage position can be found more quickly and conveniently, and then the water leakage position is treated. Even if the user does not find the alarm signal, the water source of the water leakage is cut off because the valve of the main pipeline is closed, no more water leakage exists, and the loss control caused by the water leakage is ensured to be in the minimum range. The signal transmitting module 104 of the present invention can adopt the following modes besides transmitting wireless signals to the receiving end:
1. the mode without an execution mechanism can be adopted, and the signal transmitting module 104 directly transmits a wifi signal to the gateway, and then transmits a corresponding signal to the mobile phone of the user to give a relevant warning to the user;
2. the signal transmitting module 104 may not directly transmit a signal to the actuator, but may transmit the signal to a relay controller in the belonging area, such as a favorite classmate installed in a family, and the relay controller then transmits a corresponding control signal to the actuator to execute a corresponding action;
3. the signal transmitting module 104 transmits a signal to a corresponding switching device, such as an intelligent socket, and after receiving the signal from the signal transmitting module 104, the intelligent socket turns on the actuator and the socket, so that the actuator performs a corresponding action.
In order to conveniently realize the wireless signal connection between one or more water leakage monitoring devices 1 and the actuating mechanism, a wireless signal matching scheme is adopted.
The method comprises the following specific operations:
1. the matching button of the signal receiving matching module of the actuating mechanism is pressed, the matching indicator light is on,
2. pressing down a test button of a signal matching/testing module 103 of the water leakage monitoring device 1, and enabling a matching indicator lamp to be on;
3. and completing matching.
And (3) signal testing:
after the signal matching is completed, in order to ensure that the position and the distance where the water leakage monitoring device 1 is placed are proper, the wireless signal sent by the water leakage monitoring device 1 can be received by an executing mechanism, and a test operation is required to be performed: the signal matching/testing module 103 of the water leakage monitoring device 1 is provided with a button, when the button is pressed, the water leakage monitoring device 1 sends out a wireless signal, the actuating mechanism receives the wireless signal, and the valve of the actuating mechanism is closed.
As shown in fig. 1 and 2, the power module 102 in this embodiment includes a battery 14 and a power monitoring module for monitoring the power of the battery 14, the power monitoring module is also mounted on the PCB 16, the battery 14 is mounted in a battery slot of the lower cover 15, and the battery cover 13 is covered on the outer side. In order to make the power module stand by with zero power consumption, two measures are adopted: first, the power module 102 and the signal matching/testing module 103 are in an open circuit state in the standby state; second, the power module 102 and the sensing module 106 are in an open circuit state in the standby state. Because power module zero power consumption standby, in order to prevent that long-time standby from leading to power module's battery to exceed the battery shelf life (the kind of battery is many, the battery shelf life of different grade type is different, the shelf life of battery is 3~5 years under the normal condition), and lead to leaking monitoring transmitting terminal 1 and the unable normal work of control protection end that leaks, electric quantity detection button and electric quantity pilot lamp have been set up in power module, long-time standby or accomplish once work (leak monitoring device 1 detects and leaks, and accomplished alarm signal and radio signal transmission), regularly (for example, 1 month) detect the electric quantity (press electric quantity detection button, the green lamp of electric quantity sufficient electric quantity pilot lamp volume, the red lamp of electric quantity insufficient charge pilot lamp volume).
In order to reduce power consumption and ensure wireless signal transmission, a set of wireless signal transmitting and receiving method is designed, and a signal transmitting module and an executing mechanism receiving module of a water leakage monitoring wireless transmitting end both adopt an intermittent working mode; in order to reduce power consumption, guarantee wireless signal intensity simultaneously, and realize longer alarm time, the signal emission module and the alarm module of monitoring wireless transmitting terminal that leak all adopt intermittent type nature working method, have designed one set of alarm signal and signal emission module's wireless signal emission and have worked the mode as follows:
firstly, because the power consumption is large when the wireless signal is transmitted, the total time length of the wireless signal is firstly controlled, that is, the wireless signal output for enough times is ensured to be realized in the total time length, and it is ensured that the water leakage control protection terminal 2 can receive effective signals not less than once in the total time length, that is, the output time length of the signal transmitting module is greater than the total time length of working and intermittence of the signal receiving module in one period (on the premise that the water leakage monitoring device 1 and the executing mechanism are within an effective distance). As shown in fig. 4, in the present embodiment, the total time length of the wireless signal is 2S, and the actuator receives the valid signal twice (the signal cycle time length of receiving one time is 1S). Second, as shown in fig. 3, the wireless signal is output intermittently; thirdly, intermittently outputting an alarm signal; fourthly, in order to enable the wireless signal module and the alarm signal to work at different times, a relay assembly mode is adopted, namely, the wireless signal module is in the intermittence of the alarm signal when transmitting the wireless signal, and the wireless signal module is in the intermittence of the wireless signal when transmitting the alarm signal.
Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many variations or modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
