The host module embedded program functions as follows:

data acquisition: data acquisition is completed through an RS-485/Modbus bus, and the acquisition objects comprise a digital ammeter, a vibration sensor and the like, and at most 12 Modbus terminal devices.

Forming a data frame: at least two kinds of data frames are required to be formed, wherein one kind of data frame is a large data frame in normal operation, and the other kind of data frame is a small data frame in no commercial power.

Uploading data: one or more of NB-iot, 4G, RJ-45 network port, RS-232 interface upload data according to ROM settings and instructions, where the destination address and port of the first three channels can be set, and the protocol (TCP or UDP) of the 4G and RJ-45 network ports can be set.

Energy conservation: detecting whether the current power supply is commercial power or a battery, if the current power supply is the battery power supply, entering an energy-saving state, and starting up and uploading necessary data at regular intervals in the energy-saving state.

The workflow of the host module is as follows:

2.1 the main parameters that need to be set in flash first include:

basic parameter ID, version number, etc

When the condition is triggered or data exists, repeated receiving, packaging, sending and the like are carried out.

The host module for receiving and processing signals is accessed to various sensors or original facility instrument interfaces for data communication acquisition, analog or digital signals are acquired, are received, processed and packaged by the host module, information is transmitted to a relay or a central server by a wireless network channel through a transmission protocol, and the analog or digital information indirectly or directly reflects the electrical performance parameters of the facility, such as the electric power, the environment, security and protection, and auxiliary facilities (such as an air conditioner, a battery pack, a UPS and the like), is uploaded to the center and converted into readable information, so that managers can control the actual operation condition of remote multiple targets, judge according to big data, issue the information to designated personnel, or send pairs under the command of the center commander, and carry out operation maintenance and emergency treatment. And displaying remote target multi-data summary in real time, and performing equipment inspection and active fault alarm handling. The real-time data helps management personnel to perform decision analysis, can determine the acquired content and frequency according to the monitoring platform instruction, and can upload data to the platform according to an appointed format or push related data to other departments or units to realize data sharing.

The Modbus has the function of multi-channel data concurrent acquisition, and provides various data acquisition through the Modbus industrial bus. The existing power supply battery pack monitoring system is developed to have the advantages of position positioning (GPS or base station positioning), mobile alarm, vibration alarm, electrical parameters (voltage, current and power), environment (temperature and humidity, PM2.5 dust and dangerous water inflow early warning) parameters, switch states (working and non-working, normal and abnormal, fault states and the like), power supply battery pack quality (monitoring voltage, internal resistance and current contact temperature data discrimination), danger (arc light, trip sound and abnormal sound) detection, animal entering and video monitoring, and unattended remote-program inspection is realized.

The universal or improved structure of the upper cover and the lower cover is suitable for monitoring various electrical environments. Only the internal programs or interfaces are changed, more kinds of data acquisition and transmission are realized, and a whole set or part of sensing equipment is customized and produced according to the needs of users.
