Embodiment 1

[0094] like image 3 As shown, a control method of a sensing quantity monitoring control system includes the following steps.

[0095] S1) The sensing quantity control cabinet 2 sends a reading instruction to read the monitoring information of the sensing quantity to at least one sensing quantity monitoring module 1 through the Modbus protocol.

[0096] S2) At least one sensing quantity monitoring module 1 monitors the monitoring information of the sensing quantity of the device, converts the monitoring information into digital quantity monitoring information, and feeds back the digital quantity monitoring information to the sensing quantity Control cabinet 2.

[0097] S3) The sensing quantity control cabinet 2 receives and processes the monitoring information transmitted by each sensing quantity monitoring module 1, and is used for local display of the processed monitoring information, and the monitoring information Pass it to the local user information module 3.

[0098]S...

Embodiment 2

[0101] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the following steps are also included before the step S1).

[0102] S01) Sensing quantity control cabinet 2 creates a task, the task includes refreshing the display interface of the liquid crystal display 21, detecting the input command of the input interface of the liquid crystal display 21, collecting the monitoring information of the sensing quantity and monitoring the switch quantity.

[0103] S02) The sensing quantity control cabinet 2 selects the data communication mode, and selects the WIFI module 24 or the CAN communication module 25 to realize communication.

[0104] S03) Configure the initialization parameters of the communication module in the communication mode.

[0105] For example, when selecting the WIFI module 24 to realize communication, it is necessary to set the IP address of the network connection of the WIFI module 24, the port number, the router name and the r...

Embodiment 3

[0108] like Figure 5 to Figure 7 As shown, the difference between this embodiment and Embodiment 2 is that the step S1) further includes the following steps.

[0109] S11) When the switch connected to the sensing quantity control cabinet is activated, an external IO interrupt is triggered; the microcontroller processes the IO interruption and reads the action state of the switch quantity;

[0110] When the micro-control unit starts the timer, a timing interruption is triggered, and the timing interruption is triggered every 10 ms, and each time the timing interruption is triggered, the micro-control unit performs an input scan of the display interface;

[0111] At the beginning of the application program of this system, the timer (TM3) will be started, and the highest interrupt priority will be obtained, and it will be interrupted every 10ms.

[0112] S12) In the monitoring information task of collecting sensing quantities, the micro-control unit obtains input instructions f...

Abstract

The invention discloses a sensing quantity monitoring control system which comprises at least one sensing quantity monitoring module, a sensing quantity control cabinet and a local user information module. The sensing quantity monitoring modules are correspondingly mounted on a device needing to be monitored and used for acquiring monitoring information of sensing quantity of the device, transforming the monitoring information into monitoring information of digital quantity and transmitting monitoring information of the digital quantity, the sensing quantity control cabinet is used for receiving and processing the monitoring information transmitted by the sensing quantity monitoring modules, locally displaying processed monitoring information and uploading the processed monitoring information, and the local user information module is connected with the sensing quantity control cabinet and used for receiving and processing monitoring information transmitted by the sensing quantity control cabinet, locally displaying and storing the monitoring information and uploading the monitoring information to a cloud end. The invention further discloses a control method of the sensing quantity monitoring control system.

Description

technical field [0001] The invention relates to the fields of communication, fire protection and the like, in particular to a sensing quantity monitoring and control system and a control method thereof. Background technique [0002] In the fire protection system of a large building, due to the large number of floors and the variety and quantity of fire protection equipment, such as fire elevators, fire hydrants, emergency lighting, fire shutters, etc., in order to ensure fire safety, it is necessary to monitor the fire protection system in real time. In order to ensure that the fire-fighting equipment works normally in the event of a fire-fighting accident. [0003] In a large number of fire monitoring systems, when monitoring fire equipment, it is necessary to monitor the voltage, current, power of the live equipment, and the temperature and humidity of the equipment in the working state. During monitoring, there are often many such as The sensing quantities of pressure, f...
