However, in the above-mentioned conventional indoor environment monitoring system, since the temperature and humidity control sensor and the monitoring sensor are provided separately, errors occur in the data related to the indoor environment, which reduces the reliability of research data. The problem is that In addition, because it is not possible to systematically investigate the cause of an abnormality, it takes time to investigate the cause.

The present invention solves the above-mentioned problems.The present invention unifies the functions of controlling the indoor environment and monitoring data related to the indoor environment, thereby realizing an indoor environment that is highly functional, space-saving, and cost-saving. The purpose is to provide a monitoring system.

[Means to solve the problem]

To this end, the indoor environment monitoring system of the present invention
An air conditioner 1 and a reheater 6 installed in each of the plurality of rooms 9 to control the temperature and humidity of the room, a valve controller 2B that controls the amount of hot water supplied to the reheater, and a temperature sensor 12 provided in the room. and a humidity sensor 13, a remote station scene 16 that controls the air conditioner and the valve controller based on signals from both sensors, and a central processing unit 19 connected to the remote station scene of the plurality of rooms; By reading the indicated values of the controller 26, the temperature and humidity monitoring data of a plurality of rooms is collected at predetermined time intervals to the central processing unit and is output.

Note that the numbers added to the above configurations are for comparison with the drawings to facilitate understanding, and the configurations of the present invention are not limited thereby.

[Effect]

In the present invention, for example, as shown in FIG. 1, the temperature sensor 12 is used for both temperature control and monitoring, and the sensor instruction value is taken out as an electrical signal from the valve controller 2e, and the data is converted in the remote stationary cylinder 16. Similarly, the humidity sensor 13 and the differential pressure sensor 1
The signal No. 5 is also converted into data. The converted monitoring data is collected by the central processing unit 19 at regular intervals,
The data stored in the auxiliary storage device 22 is stored in the printing device! It is launched by 23. The maximum value, minimum value, and average value of the launch data are output for each room, date and time, and month.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows one of the indoor environment monitoring systems of the present invention.
FIG. 2 is a configuration diagram showing an example.

In the figure, 1 is an air conditioner consisting of a blower fan 2, a cooler 3, and a humidifier 5. The air conditioned by the air conditioner 1 is heated in a reheater 6, and is supplied into a room 9 through a filter 7. be done. A hot water supply pipe 10 is connected to the reheater 6, and the amount of hot water supplied is controlled by a motor valve 11.

Further, inside the room 9, a temperature sensor 12, a humidity sensor 13, and a differential pressure sensor 15 are installed.

Although only one room 9 is shown in the figure, in order to control and monitor the temperature and humidity of multiple rooms, a remote station 16 is provided for each room, and each remote station is connected to a data bus 17. It is connected to the central processing unit 19 that constitutes the building management system via. The central processing unit 19 also includes a display device 20 such as a CRT, an input device 21 such as a keyboard or a light ben,
An auxiliary storage device 122 such as a floppy disk and a printing device 23 are connected.

The temperature sensor 12 is connected to the remote stationary cylinder 16 via a signal converter 25 that converts current to voltage, and the motor valve 11 is also connected via an indicator type valve controller 26. In addition, the humidity sensor 13
and differential pressure sensor 15 are connected, and further, air conditioner 1 is connected via power control panel 27.

The operation of the indoor environment monitoring system of the present invention having the above configuration will be explained.

At the remote station 16, the temperature sensor 12
The signals from the humidity sensor 13 and the humidity sensor 13 are processed, and the output signals are sent to the power control panel 27.
The cooler 3 and humidifier 5 are controlled, and the amount of hot water supplied to the reheater 6 is controlled by driving the motor valve 11 that sends an output signal to the valve controller 26 . In this way, the temperature and humidity in the room 8 are controlled to be within a preset range.

The environment inside the room 9 is monitored as follows.

(2) The temperature sensor 12 is used for both temperature control and monitoring, and takes out the sensor instruction value as an electrical signal from the valve controller 26, and converts the data in the remote station 16. Similarly, remote station 1
6, the signals from the humidity sensor 13 and the differential pressure sensor 15 are also converted into data.

- The upper and lower limits of temperature and humidity are monitored every 5 minutes, and in the event of an abnormality, an alarm will be sounded and a mark will be placed on the printed sheet to be described later. The upper limit value and the lower limit value may be set to two levels, a caution alarm value and an abnormal alarm value, and a chime may be sounded when the caution alarm value is reached, and a bell may be sounded when the abnormal alarm value is set.

■ Valid/invalid registration of a room to be monitored and setting of upper and lower limits are performed using an input device 21 such as a keyboard or a light pen. The converted monitoring data is collected by the central processing unit 19 every 30 minutes and stored in the auxiliary storage device 22.

(2) The accumulated data is printed out by the printer 23 by the operator the next day. The launch data is for each chamber,
The maximum value, minimum value, and average value are output according to date and time and month.

〔Effect of the invention〕

As described above, according to the present invention, by unifying the indoor environment control and indoor environment data monitoring functions and integrating them with the building management system,
It is possible to realize high functionality, space saving, and cost saving, and it is also possible to improve the reliability of monitoring data and research data.
