Micro computer radio measuring and control instrument for solar water heater

Abstract

A microcomputer wireless measurement and control instrument for solar water heaters (Fig. 5) consisting of a host (Fig. 1) and a transmitter (Fig. 2). The transmitter is mounted on the solar and the sensor is connected to the transmitter end. The host has a power supply circuit-8, a central processing system-3, a key input circuit-2, a wireless receiving module-6, a scanning display circuit-1, an actuator circuit-7, a sounding circuit-5 and a power-off memory circuit-4. There is a launch module-3 on the launcher. It is characterized in that the transmitter has a data acquisition circuit-5, a central processing system-1, a solar power supply system-4 and a power-off memory circuit-2. There is a wireless communication between the host and the transmitter. There are code sockets on the host and the transmitter (J4 in Figure 1, J1 in Figure 2). The code address can be modified or calibrated through the cable connection, and the data is received by the address code. There is no sensor connection on the main unit, and there is no need to pull cables or punch holes in the wall during installation. It can be installed anywhere in the room, and the operation is very convenient. One or more hosts can receive single-point data, and the use of multiple hosts is especially suitable for users who use a single solar energy on multiple floors.

Description

Technical field [0001] The invention relates to a solar water heater measurement and control device, in particular to a wireless measurement and control instrument with a data acquisition circuit, a central processing system, a solar power supply system and a power-off memory circuit on a transmitter. Background technique [0002] At present, the known solar water heater microcomputer controller all adopts elongated cables to lead the sensor from the solar water heater water tank to the indoor and host to be connected. Operations such as pulling cables and punching holes on the wall are required during installation. The installation of a well-decorated house seems very troublesome, and it is also inconvenient for users who use a single solar water heater on multiple floors. Contents of the invention [0003] In order to overcome the above deficiencies. The invention provides a wireless measuring and controlling instrument. It is composed of host and transmitter. There i...
