Detailed Description
Fig. 1 is a schematic structural diagram of a remote measurement and control terminal with a sensing function according to an embodiment of the present application.
referring to fig. 1, this embodiment provides a remote measurement and control terminal with a sensing function, including: the monitoring circuit 220 is used for monitoring the working condition information of the remote measurement and control terminal 200; and a processor 210 connected to the monitoring circuit 220, wherein an input of the processor 210 is connected to an output of the monitoring circuit 220 and is configured to process the input signals and control the peripheral device 100.
As described in the background art, the existing remote measurement and control terminal has no sensing function and cannot monitor the working condition information (such as temperature, humidity, etc.) of the application environment. Therefore, the remote measurement and control terminal is easy to break down, the measurement and control failure is caused, the service life of the remote measurement and control terminal is short, and the economic and labor cost of maintenance or replacement is increased.
to the technical problem, the remote measurement and control terminal 200 of the present application includes a monitoring circuit 220 for monitoring the operating condition information of the remote measurement and control terminal 200. The output terminal of the monitoring circuit 220 is connected to the input terminal of the processor 210, and the processor 210 periodically reads the condition information (where the condition information may be, for example, temperature or humidity) of the monitoring circuit 220, and if one of the condition information exceeds a predetermined condition threshold, the processor 210 may control the peripheral device 100 to perform related improvement measures or stop part of the non-emergency task according to the priority. The peripheral device 100 may be, for example, a rain gauge or a water level gauge, which are different peripheral devices connected to the remote measurement and control terminal 200 in an actual application scenario.
Therefore, the monitoring circuit is arranged in the remote measurement and control terminal, and the working condition information of the remote measurement and control terminal is monitored by the monitoring circuit. Therefore, the remote measurement and control terminal can perform early warning and improvement measures according to the working condition information monitored by the monitoring circuit, and the remote measurement and control terminal can sense and monitor the working environment. Therefore, the possibility of the remote measurement and control terminal breaking down is reduced, and the service life of the remote measurement and control terminal is prolonged. And reduces the economic and labor costs of repair or replacement.
Optionally, the monitoring circuit 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.
Fig. 2 shows a schematic structural diagram of the monitoring circuit according to this embodiment, and referring to fig. 1 and fig. 2, an output end of the temperature and humidity sensor is connected to an input end of the processor 210.
Therefore, the temperature and the humidity of the remote measurement and control terminal can be monitored according to the temperature and humidity sensor in the monitoring circuit 220, and the temperature and the humidity are the 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 100 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. The remote measurement and control terminal senses and monitors the working environment of the remote measurement and control terminal, and therefore the possibility of faults of the remote measurement and control terminal is reduced.
Optionally, the output end of the temperature and humidity sensor is further connected with a power supply through a resistor.
Referring to fig. 2, the interface of the output end of the temperature and humidity sensor includes a Serial Clock (SCL) interface and a Serial Data (SDA) interface, and the Serial Clock (SCL) interface and the Serial Data (SDA) interface are connected to the processor 210 and are also connected to the power supply through a resistor, so as to meet the pull-up driving requirement of the interface of the temperature and humidity sensor.
Optionally, the temperature and humidity sensor is SHT20, and the resistance value of the resistor is 10K Ω.
specifically, the temperature and humidity sensor SHT20 has the advantages of low cost, stable performance and wide application field.
Optionally, the remote measurement and control terminal 200 further includes: an early warning module 230 coupled to the processor 210.
Fig. 3 shows a schematic structural diagram of a remote measurement and control terminal with a sensing function according to an embodiment of the present application. Referring to fig. 3, the remote monitor and control terminal 200 further includes: an early warning module 230 coupled to the processor 210. In the remote measurement and control terminal 200, the temperature and humidity sensor monitors temperature and humidity, and if one of the monitored temperature value and humidity value exceeds a predetermined working condition threshold (where the working condition threshold is a temperature threshold or a humidity threshold), the processor 210 controls the early warning module 230 to alarm.
Optionally, the early warning module 230 includes an indicator light and a buzzer.
Specifically, for example, when the temperature value or the humidity value exceeds the predetermined operating condition threshold value in the remote measurement and control terminal 200, the processor 210 controls the indicator lamp and the buzzer of the early warning module 230 to alarm, for example, the indicator lamp may flash and the buzzer may sound to alarm.
Optionally, the remote measurement and control terminal 200 further includes: a wake-up circuit 240 coupled to the processor 210; wherein an output of the wake-up circuit 240 is coupled to the processor 210 and configured to wake-up the processor 210 according to a signal of the peripheral device 100.
Referring specifically to fig. 3, the remote measurement and control terminal 200 further includes: a wake-up circuit 240 coupled to the processor 210, wherein an output of the wake-up circuit 240 is coupled to the processor 210, and configured to wake-up the processor 210 according to a signal of the peripheral device 100.
For example, the peripheral device 100 is illustratively selected to be a water level gauge. At this time, the output end of the water level meter is connected to the wake-up circuit 240, the wake-up circuit 240 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. After the water level gauge measures the change of the water level, the level of the output interface of the water level gauge changes, so that the input end of the wake-up circuit 240 generates high-low level jump. Therefore, the output end of the wake-up circuit 240 generates high-low level jump along with the input end thereof, so as to form an external interrupt 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 240 after being woken up. Therefore, the real-time monitoring of the water level change is realized.
Referring specifically to fig. 4, which is a schematic structural diagram of the wake-up circuit 240, the wake-up circuit 240 includes a transparent latch, an 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 is grounded through a capacitor. The model number of the diode is IN4148, the resistance value of the first resistor is 100K omega, the resistance value of the second resistor is 100K omega, the capacitance value of the capacitor is 100nF, and the model number of the transparent latch is 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.
The water level meter is, for example, a gray float water level meter. 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. 4, latch terminal C of transparent latch 74HC573 is coupled to an I/O interface of processor 210, and output terminal Q of the transparent latch is coupled 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 a Gray code output interface of the water level meter, 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 at low level, and at this time, the processor 210 can read the water level data of the current water level meter. Therefore, the remote measurement and control terminal 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: a communication module 250 and a storage module 260 coupled to the processor 210.
optionally, the communication mode of the communication module 250 is wired communication or wireless communication.
Specifically referring to fig. 3, the remote measurement and control terminal 200 further includes: a communication module 250 and a storage module 260 coupled to the processor 210. The storage module 260 may be an SD card, for example. The communication mode of the communication module 250 is wired communication or wireless communication, and the wireless communication may be, for example, a wireless communication mode such as zigbee or bluetooth.
Therefore, the monitoring circuit is arranged in the remote measurement and control terminal, and the working condition information of the remote measurement and control terminal is monitored by the monitoring circuit. Therefore, the remote measurement and control terminal can perform early warning and improvement measures according to the working condition information monitored by the monitoring circuit, and the remote measurement and control terminal can sense and monitor the working environment. Therefore, the possibility of the remote measurement and control terminal breaking down is reduced, and the service life of the remote measurement and control terminal is prolonged.
