FIG. 1 is a schematic structural diagram of a remote measurement and control terminal system capable of waking up according to water level changes according to the present application.
Referring to fig. 1, this embodiment provides a remote measurement and control terminal system capable of waking up according to water level change, including: a water level gauge 100, and a remote monitor and control terminal 200 connected to the water level gauge 100. Wherein, the water level gauge 100 is used for measuring water level and water level variation; the remote monitor and control terminal 200 includes: a processor 210 configured to process each input signal; and a wake-up circuit 220 connected to an input of the processor 210, wherein an input of the wake-up circuit 220 is connected to an output of the water level meter 100, and an output of the wake-up circuit 220 is connected to an input of the processor 210 and configured to wake up the processor 210 according to a water level change.
as described in the background art, when the existing remote monitoring and controlling terminal system is used for monitoring rainfall and water level, the monitoring is performed at regular time, generally, once monitoring is performed for 5 minutes. Therefore, the water level monitoring device can only monitor the water level at a certain time point, and cannot monitor the water level change in real time, so that the water level monitoring effect is not ideal enough. Especially when the device is applied to a complex environment and needs to pay close attention to water level change, the influence of the water level change which cannot be monitored in real time on monitoring work is larger.
Aiming at the technical problem, the output end of the water level meter 100 is connected with the wake-up circuit 220, the wake-up circuit 220 is configured to wake up the processor 210 of the remote measurement and control terminal 200, and the processor 210 after wake-up reads the measurement data of the water level meter 100. After the water level meter 100 measures the water level change, the level of the output interface of the water level meter 100 changes, so that the input end of the wake-up circuit 220 generates high-low level jump. Therefore, the output end of the circuit generates high and low level jump along with the input end of the circuit, so as to form external interruption to wake up the processor 210 of the remote measurement and control terminal 200, and the processor 210 reads the water level data latched by the wake-up circuit 220 after being woken up. Therefore, the real-time monitoring of the water level change is realized.
Therefore, in the embodiment, the wake-up circuit 220 is arranged in the remote measurement and control terminal system, and the processor 210 of the remote measurement and control terminal 200 is awakened to read water level data according to the water level change measured by the water level meter 100 by using the wake-up circuit 220, so that the real-time monitoring of water level change is realized, and the water level monitoring result is more timely, effective and accurate.
optionally, the wake-up circuit 220 includes a latch circuit 221, wherein an input of the latch circuit 221 is connected to an output of the water level gauge 100 and an output of the latch circuit 221 is connected to an input of the processor 210.
Wherein fig. 2 shows a schematic diagram of the wake-up circuit 220 according to the present application, referring to fig. 2, an input terminal of the latch circuit 221 is connected to an output terminal of the water level meter (gray code float water level meter) 100, and an output terminal of the latch circuit 221 is connected to an input terminal of the processor 210.
Therefore, the present embodiment can cause the level change at the output end of the water level meter 100 according to the water level change measured by the water level meter 100, and the characteristic that the latch circuit 221 is sensitive to the level is utilized, so as to wake up the processor 210 of the remote measurement and control terminal 200 to read the water level data, thereby realizing the real-time monitoring of the water level change, and making the result of the water level monitoring more timely and effective.
Alternatively, the latch circuit 221 includes a transparent latch, an input terminal of which is connected to a diode, wherein the diode is connected in series with one end of a first resistor, and the other end of the first resistor is connected to an input terminal of the transparent latch, and the input terminal of the transparent latch is connected to a power supply through a second resistor, and to ground through a capacitor.
Referring to fig. 2, the latch circuit 221 includes a transparent latch. Wherein the input terminal of the transparent latch is connected to a diode, wherein the diode is connected in series with one end of a first resistor, and the other end of the first resistor is connected to the input terminal of the transparent latch, and the input terminal of the transparent latch is connected to a power supply through a second resistor, and to ground through a capacitor. The power supply and the circuit safety of the latch circuit are ensured through the connection with the power supply and the grounding of the capacitor.
Alternatively, the diode is IN4148 and the first resistor has a resistance of 100K Ω.
Alternatively, the resistance value of the second resistor is 100K Ω, and the capacitance value of the capacitor is 100 nF.
Optionally, the transparent latch is model 74HC 573.
Specifically, the transparent latch with the model 74HC573 is a transparent latch with eight outputs, where OC is an enable terminal, C is a latch terminal, D is an input terminal, and Q is an output terminal. The enable terminal OC is always at a low level, the latch terminal C is always at a high level, and the output terminal Q varies according to the level data of the input terminal D. When the latch terminal C is low, the output terminal Q outputs the data of the input terminal D whose latch is established by the transparent latch.
optionally, the water level gauge 100 is a gray code float water level gauge.
Specifically, when the water level changes by more than 1cm, the level of a gray code output interface of the gray code float water level gauge changes. And the Gray code float water level gauge has good measuring accuracy and working stability.
Referring specifically to fig. 2, latch terminal C of transparent latch 74HC573 is connected to an I/O interface of processor 210, and output terminal Q of transparent latch is connected to an external interrupt interface of processor 210. The I/O interface of the processor 210 holds the latch terminal C of the transparent latch 74HC573 high. When the water level changes by more than 1cm, the level of a Gray code output interface of the Gray code float water level gauge changes. The input end D of the transparent latch generates high-low level jump due to the level change of the Gray code output interface of the water level meter 100, and the output end Q of the transparent latch generates high-low level jump along with the input end D to form an external interrupt awakening processor. When the processor wakes up, the latch terminal C of the transparent latch 74HC573 is controlled to be low, and at this time, the processor 210 can read the current water level data of the water level gauge 100. Therefore, the remote measurement and control terminal system of the embodiment realizes real-time monitoring on water level change.
In addition, referring to fig. 2, the gray code float water level meter of the present embodiment exemplarily shows that the gray code output interface is 13 bits, and the number of the diodes and the first resistors correspondingly connected to the gray code output interface is 13 respectively. The input end of the transparent latch is connected with a power supply through a second resistor and is grounded through a capacitor, wherein the number of the second resistor and the number of the capacitor are respectively 13. Since the 74HC573 transparent latch is a transparent latch with eight inputs and outputs, the present embodiment exemplarily configures two 74HC573 transparent latches to connect a gray code float level meter with 13-bit gray code output. And the input end D left by the 74HC573 transparent latch is grounded.
Optionally, the remote measurement and control terminal 200 further includes: the monitoring circuit 230 connected to the processor 210 is configured to monitor the operating condition information of the remote monitoring and control terminal 200.

The monitoring circuit 230 includes a temperature and humidity sensor, wherein an output terminal of the temperature and humidity sensor is connected to an input terminal of the processor. Therefore, the temperature and the humidity of the remote measurement and control terminal 200 can be monitored according to the temperature and humidity sensor in the monitoring circuit 230 in this embodiment, and the temperature and the humidity are the above-mentioned working condition information. If one of the monitored temperature or humidity values exceeds a predetermined threshold (the threshold is a temperature threshold or a humidity threshold), the processor 210 controls the peripheral device to perform an early warning and improvement measure, wherein the improvement measure may be, for example, to stop part of the non-emergency work tasks according to the priority.
