In order to enable the product to have good compatibility, the product can be externally connected with sensors of different manufacturers, and a lower computer program does not provide the analysis function of a sensor protocol during design, but an upper computer configures the product through a 4G network. The upper computer program sends a reading protocol of a sensor which needs to be connected at present to a product through a user-defined communication protocol, the product stores the reading protocol after obtaining the reading protocol, then sends 1-4 configured different reading protocols to the sensor on the bus in a polling mode according to needs, directly stores data frames returned by the sensor according to time and a sensor serial number (1-4), uploads data once a day under a default condition, uploads data of the day of 4 devices at the maximum time, uploads the data in 1-4 times, and sends the data frames in 1-2 times each time.
With the fixed location storage mode, the maximum storable single sensor return data frame length does not exceed 76 bytes +1 data length byte.
A maximum of four external devices, one data per hour, 24 hours a day, 365 days a year, 4 x 24 x 356=35040 pieces of data.
And according to the length of the maximum returned data frame, 76 bytes and +1 data length bytes, and the length of the timestamp is calculated according to 8 bytes, so that the daily occupied storage size of each sensor is as follows: (76 +1+ 8) × 24=2040 bytes.
With the W25Q6128 memory (16 Mbytes), each sector can store 48 pieces of data of 2 sensors at most (every day) when erasing operation is carried out on one sector at minimum every 4K, and if 4 sensors are accessed, storage space of two sectors is occupied every day. W25Q128 has 4096 sectors: 4096/2=2048 days; 2048/365 ≈ 5.6 years.
The default collection mode is once per hour, and all data collected on the same day are sent every day.
Can be configured in a 5-N minute timed continuous immediate acquisition mode, where data is sent directly without storage.
Besides the timing collection of 24 times per day, the collector can be controlled to carry out continuous high-density data return by remote commands.
The data inquiry function is provided, data of a certain day can be inquired through a remote command, all data in the storage can be inquired, and the storage can be formatted. A variable frame length protocol is used, since the packet length is unpredictable.
The low-power consumption acquisition equipment provides two sets of output voltages which can be adjusted by software, and the requirements of all sensors can be completely met. The power supply output controlled by the program can supply power to the sensor only when data needs to be acquired, so that the working time of the sensor is greatly reduced, the power consumption is reduced, and the service life of the sensor is prolonged.
When the low-power consumption acquisition equipment is used for building a non-long-term (within 1-2 years) monitoring system, an internal battery can be used for supplying power, external power supply is completely not needed, only the sensor is required to be considered to be embedded, and great convenience is brought to construction.
The solar charging system is arranged in the low-power-consumption acquisition equipment, and only one solar cell panel is externally connected in a system needing long-term monitoring. A whole set of solar power supply system (comprising a solar cell panel, a solar charging controller and a storage battery) is not required to be built. Greatly reducing the construction difficulty.
The low-power consumption acquisition equipment provides a one-to-four bus and a power supply interface for the external connection sensor, so that the complexity of the system is greatly reduced. 4 independent RS485& RS232 buses can let the sensor that connects on it independently use, mutual noninterference, can not influence the normal communication of other sensors when one or more sensor trouble causes the bus short circuit wherein.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
