On the other hand, since the gateway is a device that needs to run for a long time, it needs to have higher reliability and stability than the [img] eb end, so unit test and integration test are necessary, and code analysis tools are needed to ensure that the code is not available. Any memory and file handle leaks. Even in a garbage collection environment, memory leaks exist, and in embedded systems, due to limited memory, it is particularly vulnerable to leakage. Fortunately, the development of application-side Javascript has been around for a long time. Intelligent hardware can borrow a lot of tools from server development.

The non-transparent transmission mode of intelligent hardware and technology has solved this problem very well. The GRM200 module directly communicates with the PLC through 485, and the real-time communication can be completely guaranteed! Intelligent hardware can realize communication between 1:N, N:N, N:1 between the computer and the module. That is, a PLC can be monitored by configuration software on multiple computers at the same time, and one computer can also wirelessly monitor multiple PLCs at the same time. The module built-in WEB release, only need to use the computer and mobile phone to log in to the cloud monitoring website, the password and serial number of the intelligent hardware input module, and the PLC data can be viewed and modified through the webpage. PLC does not need to write any program, customers do not need to have network knowledge, just familiar with the configuration software, you can complete remote computer monitoring, PLC SMS control, SMS query, SMS alarm, and web monitoring PLC.

GPRS module company quality is good, intelligent hardware company pointed out that GPRS has 171.2kbps access speed compared to GSM 9.6kbps access speed; GSM needs 10-30 seconds in connection connection time, while GPRS only needs pole a short time you can have access to specific request; and for the cost, GSM is based on connection time billing, meter data and GPRS simply press charges; GPRS for network resource utilization and relatively much higher than GSM. GPRS module company relatively low connection cost, high resource utilization in the GSM network, GPRS first introduced the packet switching transmission mode, so that the original GSM transmission data mode using circuit-switched mode has undergone a fundamental change, which is in the wireless resources It is especially important in the case of scarcity. In the circuit-switched mode, the user will occupy the wireless channel alone regardless of whether or not data is transmitted during the entire connection period. During the session, many applications often have a lot of idle time, such as Internet browsing, sending and receiving E-mail, and so on. For the packet switched mode, the user only occupies resources during the transmission or reception of data, which means that multiple users can share the same wireless channel efficiently, thereby improving resource utilization. The billing of GPRS users is based on the amount of data communicated, reflecting the principle of “how much, how much to pay”. In fact, GPRS users may have connection times of up to several hours, but only pay a relatively low connection fee.

Intelligent hardware and online software updates are also one of the basic services provided by Ostro. This is a basic service for the application, which can quickly complete the software update of the device, and only requires a minimum amount of software downloads, only need to restart the necessary devices, without having to restart all devices. Intelligent hardware and online software updates are the core mechanisms for ensuring manageability and maintainability. Through the cooperation of the operating system and the back-end cloud platform, the software of the device is always kept in the latest and most secure state. Ostro base library: The Ostro base library includes the most basic runtime libraries that ship with the Linux kernel, such as the most commonly used C runtime libraries. Intelligent hardware, Ostro can dynamically extend the scope of the basic library as needed. Linux kernel: The Ostro kernel is a general-purpose Linux kernel that includes the most basic driver support, hardware adaptation support, network support, file system, and device management mechanisms. In order to adapt to the application, Ostro has made some fine-tuning of the Linux kernel, so that the kernel can support more sensors (Sensors), and can support more connection types, such as Bluetooth / [img] iFi / Zigbee and so on.

Single Point Load Cell

Single point load cells are a type of weight sensor, also know as parallel beam Load Cell, It will offer high accuracy and high reliability, they are widely used in small bench scales,platform scales, medical scales, light capacity filling machines packaging machines and other weighing devices.
