Sensors and instruments are the foundation of the Internet of Things

As far as the input end of sensor products is concerned, to be able to adapt to the application requirements of the Internet of Things and the comprehensive perception, the application measurement objects will become very diversified. Compared with the current products of this type, the temperature, pressure, and flow rate are fixedly measured. For several conventional physical quantities, the application scope and functional requirements of its measurement need to be greatly expanded, such as online analysis, optical fiber sensing, etc. This actually depends on the development of sensor MEMS technology.

The finally promoted program mainly focused on the terminal of the heating network, using the household heat metering technology of the on-off time on-off area method to install a thermostat in the residents' indoors. The indoor thermostat can communicate wirelessly with the controller in the tube well to control the opening and closing of the hot water valve to automatically adjust the indoor temperature of the heating level.

In recent years, the demand of the industry is still driving the development of instrumentation. Compared with international enterprises, the development of domestic enterprises has been in pace, but under the impact of new demand, it has become more and more synchronized with the market demand.

The development of the Internet of Things opens up the market breadth. Although from the application point of view, instrumentation is only a product branch under the huge scale of the Internet of Things industry, but the Internet of Things focuses on the characteristics of expanding the application field, which is equivalent to opening up many new markets for the instrumentation industry. The door has created a huge boost for it.

In this regard, Wang Yue, deputy general manager and chief engineer of Beijing Far East Instrument Co., Ltd., said: From the perspective of policy guidelines and national support, the Internet of Things has a huge role in promoting instrumentation. Currently, the Internet of Things is targeting many industries. In addition to the traditional industrial field, it also has many applications in many fields such as public safety, safe production, urban management, energy saving and emission reduction, and each type of demand has different requirements for instrumentation, so the instrumentation industry It can be said that in the face of infinite opportunities.

Application expansion seeks key technologies. In fact, sensors and instruments are the devices that constitute the basic level of the Internet of Things. The key to their technology cannot be separated from data input and output. The development of the Internet of Things, in the face of the vast application industry, also requires that relevant key technologies be resolved.

Wang Yue pointed out that, as far as the input end of sensor products is concerned, to be able to adapt to the application requirements of the Internet of Things and the comprehensive perception, its application measurement objects will become very diverse, relative to the current type of products fixed measurement temperature , Pressure, flow and other conventional physical quantities, the application range and functional requirements of its measurement need to be greatly expanded, such as online analysis, optical fiber sensing, etc. This actually depends on the development of sensor MEMS technology.

At the data output end, data transmission at the network layer is inevitably involved. This requires the output data to be unobstructed. In addition to the current fieldbus, wireless communication will also become an indispensable function for measurement products. At present, although wireless and other technologies have been widely used in some industrial occasions, due to the industry's wait-and-see attitude to its reliability, it is still in a state of being unsupervised.

When it comes to the field of instrumentation, there is still a major problem in the development of the Internet of Things, that is, the problem of interface specifications. The application breadth of the Internet of Things will inevitably involve a lot of protocols, but each manufacturer's product agreement is not the same, and there will be great obstacles in interconnection and interconnection. In addition, some instrument products required by government-led people's livelihood applications require small size, low cost, high reliability, and low power consumption, which depends more on the development of MEMS technology, which is also the future One direction needs to be resolved.

Heating metering system becomes a typical case of energy saving. For this reason, Far East Instruments also established the Internet of Things business department. Its main responsibility is to provide special solutions for applications and needs through the exploration and focus of Internet of Things applications. Among them, energy saving has become an important application field of the Internet of Things. In this respect, the heating metering system that Far East Instruments is vigorously developing and promoting is a typical practical example of energy saving in the civil Internet of Things.

Wang Yue introduced that in the past, the heating system of the residents basically did not undergo any measurement, and the heat supply was relatively extensive; and the current Beijing and other regions through the vigorous promotion of the household heat measurement system, the intention is to use this new measurement system to make full use of resources Effective use, to avoid waste to the greatest extent, and ultimately achieve the purpose of implementing heating and energy saving. On the other hand, self-regulation can be achieved through accurate measurement of residents ’heat supply, gas supply, and even electricity supply, and heat can be used as needed, saving real money for residents.

The finally promoted program mainly focused on the terminal of the heating network, using the household heat metering technology of the on-off time on-off area method to install a thermostat in the residents' indoors. The indoor thermostat can communicate wirelessly with the controller in the tube well to control the opening and closing of the hot water valve to automatically adjust the indoor temperature of the heating level. Using the functions of the entire system, these related data can be automatically fed back to the data collection box, and further summarized to the upper heating data management platform through GPRS and other communication methods.

It is pointed out that compared with the previous fixed heating method, the user can adjust the heat according to the demand to meet the living comfort requirements, causing a fluctuation in the total heating amount macroscopically, and providing energy-saving space for the heat source factory. And it is through the heat metering system that the heat source factory can collect relevant data as a reference, so that the output of the heat source is more reasonable, and ultimately achieve the purpose of energy saving. This is a typical case of the integration of instrumentation into the Internet of Things.

Speaking of, in terms of heating measurement, benefiting from the vigorous promotion of the government society, this type of product is expected to have an explosive demand within five years. He also pointed out that with the increasing application requirements in various fields in the future, instrumentation will continue to face new research and development needs. Still taking the energy-saving and emission-reduction field as an example, many specific applications still lack special instrumentation products, which will promote R & D and industrialization of the instrumentation industry.
