In order to make it easy to understand, being described in detail below for the principle of above-mentioned temperature and humidity remote monitoring instrument.
It is emphasized that the requires of the utility model protection be temperature and humidity remote monitoring instrument composition and structure, into
Row principle when introducing related treatment process can be routine techniques.
As shown in Figure 3, the processing unit in temperature and humidity remote monitoring instrument is the CPU of monitor, by with digital temperature
Humidity sensor communication.
1, under normal condition, external AC power source is converted to direct current by AC-DC power-switching circuit, is that temperature and humidity is remote
Each component of journey monitor is powered, while being charged by charge-discharge circuit to chargeable backup power source.Processing unit acquires number
The real time temperature and humidity data that word formula Temperature Humidity Sensor senses, and preliminary treatment and judgement are carried out, if data are normal,
Then data are shown over the display, while by wireless transport module, the data of acquisition being uploaded in cloud platform in real time.
2, abnormal condition includes two kinds of situations: external AC power failure and communication failure；Under both failures
Treatment process is as follows:
1) external AC power failure.
Processing unit constantly detects external AC supply voltage, when external alternating voltage is too low, it is believed that AC power source event
Hinder external power supply to interrupt, backup power source automatic power；At this point, processing unit can send out power-off report by wireless transport module
Alert information；Meanwhile disconnection of wireless communication module power switch, the power supply to wireless transport module is cut off, to reduce backup power source
(wireless transport module power consumption is larger, larger to the consumption of backup power source, may result in backup power supply and holds time not for consumption
It is enough, if cost and volume can all increase using the backup power supply of larger capacity).Processing unit still continuous collecting simultaneously
Data of the Temperature and Humidity module, and store into memory.When processing unit detection external communication supply voltage restores, processing unit is connected
After the power supply of wireless transport module, with cloud monitoring platform successful connection, the data during power-off are taken out to upload from memory
It is gone on to cloud monitoring platform.
2) communication failure.
Processing unit detects the connection status of wireless transport module and cloud monitoring platform server, if it find that wireless transmission
Collected data of the Temperature and Humidity module, then be directly stored in memory by the monitoring platform server disconnecting of module and distal end,
When wireless transport module and the connection of the monitoring platform server of distal end restore, then by data collected during communication disruption
It is taken out from memory and uploads to monitoring platform up.
As previously mentioned, processing unit can be single-chip microcontroller or embedded system.It will be understood by those skilled in the art that at present
Single-chip microcontroller or embedded system can integrate (loading) in advance and have some conventional processing, testing mechanism, to realize text
In be previously mentioned data acquisition, preliminary treatment and judgement to data, voltage detecting, warning message transmission, be switched off/on nothing
The functions such as the power supply of line transmission module, the detection of connection status.In other words, every processing mentioned in text, testing mechanism be all
It can be realized by routine techniques, the utility model only protects the composition and structure of temperature and humidity remote monitoring instrument.
Property introduction is as it can be seen that above-mentioned temperature and humidity remote monitoring instrument has data temporary and alarms and resume function based on the above principles
Can: by internal chargeable backup power source, power supply is provided in external AC power failure power failure, it is ensured that temperature and humidity prison
Surveying instrument can be with alert, while guaranteeing the data of the Temperature and Humidity module continuous collecting during power-off, and the data of acquisition are stored
In the memory inside temperature-humidity monitoring instrument.Memory inside temperature-humidity monitoring instrument can also be communicated in communication network failure
The data of the Temperature and Humidity module that continuous collecting is saved when interruption, the acquisition of temperature-humidity monitoring data is interrupted when solving the problems, such as to break in the communications.
When external alternating current restores electricity with communication recovery, number that temperature-humidity monitoring instrument will store during power failure or communication disruption
According to uploading on monitoring platform.In addition, can also be supplied to equipment management and maintenance personnel in time in power failure external power supply
Disconnected information alert, improves troubleshooting efficiency, and reduction manages and maintains personnel labor intensity.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
