Product Description

ZDW-F20G GPRS temperature and humidity recorder
I. Introduction
ZDR-F20G-based GPRS temperature and humidity recorder is a large instrument Co., Ltd. Hangzhou Ze developed a new generation of transmitters, while retaining the original recorder function, based on an increase of GSM-GPRS module. No need for wiring and control site computer, GSM-GPRS module can be inserted SIM card, the data transmitted directly to the software to set the IP address and a good phone. Connect to the Internet through mobile networks, without broadband, easy installation, GPRS communications traffic is extremely small, less than traffic on 20M. Automatic time management system server to transmit real-time data and historical data, users can remotely modify the recorder settings. Various kinds of imported original internal or external sensors, data acquisition system is not stored in volatile memory.
Second, functions and features
u live real-time display and record temperature and humidity changes in the scene.
u large screen display, simple operation and reliable performance.
u use GPRS transmission, without on-site wiring. Use of digital sensors, data integration, high precision.
u data can be uploaded regularly to the data server. Use of personnel in accordance with the requirements set upload time interval. Data server can always see through the historical data, curve. Can check any day in January, one year of data.
u have a short message with real-time data query temperature and humidity, excessive SMS alarm function.
u can set the temperature and humidity gauge distance phone alarm on the floor.
u Do not install equipment or metal screen in the corner office block materials, such as can not avoid to use an external antenna (not standard).

V. Installation
1, the proposed monthly fee does not need to buy a GSM mobile phone network card (with no SIM card), China Mobile and Unicom can (preferably monthly GPRS traffic). In the case of no electricity, the SIM card into the SIM card interface can be.
2, if the external sensor, air sensor plug and socket logger connected to the air (note the matching pin and socket), then plug in the power.
3 random with the RS232 communication line to the receiver connected to the computer.
4, installation of officers with special configuration tools on the equipment of the time, upload ID, upload IP, upload interval and other parameters to be configured.
6, running on the computer recorder applications, set up on-site recorder and the necessary parameters of the actual number of units can be.
7, is set up, GPRS transmitter will be fixed in place need to detect from the ground 1.7M office, connected to power.
Select SIM card note the following:
a) can only use GSM mobile phone network card, CDMA Card, 3G can not be used.
b) phone card should be opened Caller ID, or some functions can not be achieved.
c) phone card can not set the boot password, or GSM network can not log in successfully.
d) To ensure this phone card has a certain fund balance to cover the GPRS network to send text messages and landing when the costs incurred.
e) the use of mobile phone cards, before the phone is set up into the short message service center number. Short message service center number is different for each place, the specific can ask the local 10086 or 10010.
 
6, instrument settings, data upload operation method
1, GSM-GPRS module initialization state power status indicator flashes Description:
1). A second flash once, indicating the module is searching for network
2). Three seconds, flash once, indicating the module has successfully landed on the network
2, buzzer sound tips Description:
1). GSM-GPRS module initialization is complete, there will be soon as the buzzer sound prompts.
2). GSM-GPRS module receive SMS, SMS command if correct, would be soon as the buzzer sound prompts.
3). GSM-GPRS module TCP data transmission is successful, there will be soon as the buzzer sound prompts.
4). GSM-GPRS module TCP data transmission failed, the buzzer will sound two audio prompts.
5). GSM-GPRS module failed to send text messages, voice prompts will be three times the buzzer.
3, GPRS network transmission function of the realization of TCP data
1). TCP Data From time to time intervals: the smallest unit is 1 minute, in order to achieve real-time data generated in the whole point, 1 hour less than the time interval must be able to upload divisible by 60. Thus, within 1 hour time interval to be uploaded regularly: 1,2,3,4,5,6,10,12,15,20,30,60 (minutes).
2). In accordance with the time interval will upload the whole point of the beginning of real-time temperature and humidity data to a fixed IP address of the server. Interruption in the transmission network, the restoration of transmission, the automatic replacement of historical data, historical data for replacement of up to 56. Overflow of data, covering the first data according to FIFO.
3) or short message via the serial port command to set the parameters
1 TCP data transmission time interval Upload
2 server IP address and port number
3 TCP send real-time data to enable
Note: serial port settings configuration tool software reference recorder, set the reference below, the short message
4, the realization of short messaging
1) query the current temperature and humidity of real-time data
2) Set the upper and lower limits of temperature and humidity alarm
3) Set the temperature and humidity exceeded alarm switch
4) data level exceeds the short message alarm, if the data has been exceeded, message alarm time interval of 10 minutes, that the next message alarm can be triggered in 10 minutes
5, the short message commands: (not case-sensitive)
1) query temperature and humidity data
 Command format: 000WSD / / return: the current temperature and humidity data.
2) Open-channel exceeded alarm
 On all channels: 000KALLK / / returns: Open success!
 A single channel: 000KCHxK / / returns: Open success!
 Note: x is channel number, example: temperature channel (1): 000KCH1K humidity channel (2): 000KCH2K
3) Close the channel exceeded alarm
 On all channels: 000GALLG / / Return: Close success!
 A single channel: 000GCHxG / / Return: Close success!
 Note: x is channel number, example: temperature channel (1): 000GCH1G humidity channel (2): 000GCH2G
4). Set the channel exceeded the upper and lower limit alarm
   Command format: 000SCHxSyxxxSyxxx where y, x to be variable.
   CHx to access them. Said temperature channel CH1 1, CH2, said humidity channel 2 and so on. Four of a value that yxxx, only that integer. said the sign y, y that is positive for the Z, y for the F express negative. Such as the Z040 that +40; F020 said -20. Value must be an integer.
   Setting is successful, will receive "set successfully!" Prompt text.
   Complete upper and lower alarm settings, the recorder will automatically open the alarm function.
   Example: Set the temperature channel (1) Alarm upper and lower limits: 000SCH1SZ040SZ010
   This command sets the channel temperature alarm limit +40, +10 minimum. Alarm function activates.
5). Short message mobile phone number to set alarm purposes, can be set up to three numbers PHONE
   Command format 000BPnNaaaaaaaaaaaAbbbbbbbbbbbBcccccccccccC
   / / Return: Setting success.
   Note: n number of phone numbers for the set.
 aaaaaaaaaaa, bbbbbbbbbbb, ccccccccccc were three numbers (11 digits).
 If you only set one or two numbers, the remaining number of all filled with 0.
Cases: 000BP3N13173648937A13735552471B15157178385C set three numbers
    000BP1N13173648937A00000000000B00000000000C set up a number
7, system expansion
    GPRS transmitter has been reserved for the air conditioning, dehumidifiers and other equipment of the control interface, providing 24-hour on the measured temperature and humidity controlled environment to ensure that the measured indicators of environmental temperature and humidity within a reasonable range, both not excessive, not too less than the target, can be significant energy savings, cost savings and management costs.
8, Quality Assurance
The company dedicated to customer service, can be designed according to user requirements, processing and production. Three bags of product to do. The user to comply with the prescribed conditions, the instrument year warranty. There are quality issues during the warranty period, free repair.
