DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-2This application is described in further detail.
[0030] The present application discloses a remote intelligent water meter reading system. Figure 1 and Figure 2 Each water supply area is equipped with a water meter 1. In some areas, the water meter 1 is not a smart water meter 1. In order to facilitate automatic meter reading, the remote intelligent water meter reading system includes a smart meter reading device 2 respectively installed on each water meter 1. The smart meter reading device 2 modifies the original water meter 1 to improve the automatic processing and recording of data.
[0031] The smart meter reading device 2 communicates with the background service equipment database 3. The smart meter reading device 2 sends the acquired water consumption data to the background service equipment database 3 for storage. In addition, the water terminals 4 belonging to each water management area can access the background service equipment database 3 to obtain the water consumption data of the corresponding water supply area, thereby improving the efficiency of water management.
[0032] The smart meter reading device 2 includes a camera 201, mounted above the dial of the water meter 1, capable of capturing the dial image. The smart meter reading device 2 also includes a main control chip 202. In this embodiment, the main control chip 202 may be an MSP43F449. The main control chip 202 is connected to a data acquisition module 203 and an image recognition module 204. The data acquisition module 203 is connected to the camera 201. When the camera 201 captures an image of the water meter 1, the data acquisition module 203 captures the image and sends it to the main control chip 202. The main control chip 202 then causes the image recognition module 204 to recognize the image and obtain water usage data.
[0033] The main control chip 202 is also connected to a communication module 205. The communication module 205 can use a 4G / 5G communication module 205 or an RS485 communication module to enable the smart meter reading device 2 to communicate with the background service equipment database 3. The main control chip 202 can send water usage data to the background service equipment database 3.
[0034] Furthermore, the main control chip 202 is also connected to a display module 206. In the embodiment of the present application, the display module 206 can be an LCD of model J1747RM. The main control chip 202 enables the display module 206 to display water usage data, which is convenient for staff to check whether the automatic meter reading data is accurate during field investigations.
[0035] In order to facilitate intelligent control of the water meter 1, a valve 207 is provided on the pipeline where the water meter 1 is located. The main control chip 202 is connected to the valve 207 to control the opening and closing of the valve 207. The valve 207 can be a solenoid valve or an electric valve. When the pipeline needs to be controlled to be open or closed, the main control chip 202 controls the opening and closing of the valve 207.
[0036] If the valve 207 is an electric valve, the electric valve includes a motor and a mechanical valve 207, wherein the mechanical valve 207 can be selected from the existing one on the pipeline, and the motor is installed on the original mechanical valve 207, and the main control chip 202 is connected to the motor. The main control chip 202 controls the rotation of the motor, and then the motor drives the mechanical valve 207 to rotate and open.
[0037] The existing mechanical valve 207 may be aging or faulty. To monitor whether the valve 207 is opening and closing properly, the main control chip 202 is connected to a valve monitoring module 208. The valve monitoring module 208 is connected to the motor and uses the motor current to obtain the motor's operating status. When the main control chip 202 controls the electric valve to close, the flow rate of the water meter 1 changes from non-zero to zero, but the motor current is still greater than the preset value, indicating that the mechanical valve 207 is closed but the motor has not stopped. Alternatively, when the main control chip 202 controls the electric valve to open, the flow rate of the water meter 1 changes from zero to non-zero, but the motor flow rate is still greater than the preset value, indicating that the coordination between the motor and the mechanical valve 207 is abnormal. The valve monitoring module 208 then sends a signal to the main control chip 202, causing it to control the motor to stop in a timely manner, protecting the motor and reducing power consumption. On the other hand, when the main control chip 202 controls the electric valve to open or close, the flow of the water meter 1 does not change and the motor current is still greater than the preset value, then the mechanical valve 207 may be aged or faulty and not controlled by the motor. Then the valve monitoring module 208 sends a signal to the main control chip 202, so that the main control chip 202 controls the motor to stop in time.
[0038] Furthermore, the smart meter reading device 2 includes a power supply module 209, which includes a transformer 2091, a rectifier module 2092, and a positive voltage regulator 2093. The transformer is connected to the 220V AC power supply to convert the AC power into 5V AC power. The rectifier module 2092 converts the 5V AC power into 5V DC power. At the same time, the positive voltage regulator 2093 is connected to the rectifier module 2092 to stabilize the 5V DC voltage and convert the 5V DC voltage into 3V DC voltage. The 3V DC voltage is used to power the main control chip 202, and the 5V DC voltage is used to power other modules of the smart meter reading device 2.
[0039] To monitor the stability of the output voltage of power module 209, main control chip 202 is connected to a power supply voltage detection module 210 and an alarm module 211. Power supply voltage detection module 210 monitors the output voltage of power module 209. Main control chip 202 has a preset timer. At each set time, main control chip 202 interrupts monitoring operations, causing the system to enter a low-power state. Power supply voltage detection module 210 monitors the output voltage. If the output voltage falls below a lower limit, main control chip 202 causes alarm module 211 to sound an alarm and transmit an alarm message to backend service device database 3 via communication module 205, causing backend service device database 3 to indicate an undervoltage flag. The lower limit is set to 3V. If the output voltage does not fall below the lower limit, the system is interrupted and the system resumes normal monitoring operations.
[0040] To improve safety, the main control chip 202 is connected to an anti-tamper circuit 212. The anti-tamper circuit 212 includes an operating switch that is normally closed. When the water meter 1 is disassembled, the operating switch needs to be disconnected to close the valve 207 of the water meter 1. If the operating switch is not disconnected, that is, the valve 207 of the water meter 1 is closed, the alarm module 211 will sound an alarm.
[0041] The implementation principle of a remote intelligent water meter reading system in an embodiment of the present application is as follows: an intelligent meter reading device 2 is set up in each water supply area, and collects an image of the water meter 1 through a camera 201. After the data acquisition module 203 obtains the image of the water meter 1, the image recognition module 204 recognizes the image to obtain water consumption data. Then, the intelligent meter reading device 2 sends the water consumption data to the background service device database 3 through the network, so that the water terminal 4 of each water supply area can access the background service device database 3 to view the data of the corresponding water supply area. Therefore, without completely replacing the mechanical water meter 1, the meter reading can be automated, thereby improving the efficiency of water service work and being timely and safe.
[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
